Abstract
Empirical research spanning the past three decades has consistently upheld that traumatic experiences are prevalent (Gold,
Psychological Trauma Theory Research Practice and Policy, 5(1), 114-124, 2008: Kilpatrick et al. Journal of Traumatic
Stress• 26(5), 537-547. 2013: Resnick, Kilpatrick. Dansky, Saunders. & Best Journal of Clinical and Consulting Psychology
61(6), 984-991, 1993). Therefore. the likelihood of encountering an individual who has experienced significant trauma within
forensic settings is high (Dalenberg. Straus. & Ardill, 2017). Further, forensic psychologists are frequently called upon to assess
the impact of such traumatic events and to opine about their connection to a specific psycho-legal issue such as damages in a civil
case or the presence of extreme emotional disturbance or mitigating factors in criminal matters. Childhood trauma that has
occuned repeatedly and cumulatively, particularly within the context of family relationships, has been referred to as complex
trauma. Complex trauma has been shown to result in significant difficulties in a broad range of capabilities such as affect
regulation. dissociation, identity development. relational capacities, and somatic distress (Courtois and Fond 2009). The author
delineates core ethical principles and challenges encountered in forensic assessment both generally and more specifically in the
forensic assessment of complex trauma and dissociation. She also details practical strategies for responding to those challenges.
In addition, the author identifies essential skills needed for competency in this arena and outlines professional considerations that
arise when working with this population.

Psychologists, mental health professionals. researchers. and
public policy makers are becoming increasingly aware that
exposure to traumatic events is not a rare occurrence and is
related to a number of trauma-related disorders (Gold. 2008).
For example, a national study utilizing a large sample of adults
residing in the USA found that 89.7% had experienced at least
one DSM-5 Criterion A traumatic event and that many had
experienced more than one type of trauma (Kilpatrick et al.,
2013). Another study found that 69% of a sample of over
4000 US women reported having experienced a traumatic
event over the course of their lifetime (Resnick et al.. 1993).
While prevalence rates in community samples are high, stud-
ies of clinical populations have found significantly higher
prevalence rates (Mauritz, Goossens. Draijer• & van
Achterberg• 2013; Shi, 2013). Given the high prevalence rates

of trauma exposure, it is very likely that forensic psychologists
will find themselves involved in civil or criminal matters in-
volving the assessment of an individual who has experienced
at least one significant traumatic event. Although ethical prac-
tice is critical in all aspects of forensic practice. evaluating
individuals who have experienced complex trauma can pres-
ent some unique difficulties that are important for psycholo-
gists to understand. This paper will address those ethical con-
siderations that are critical for any forensic evaluation, as well
as discuss how repeated trauma can increase the complexity of
forensic practice.
Roles of Forensic Psychologists
Forensic psychologists can and frequently do perfonn varied
roles at the point of intersection between psychology and the
law, and there is a myriad of ways in which a forensic psy-
chologist can be called upon to provide specialized expertise
in the areas of trauma, complex trauma, and dissociation. A
forensic evaluator will conduct an independent psychological

evaluation in order to obtain information in response to a
specific psycho-legal question (Dalenberg et al.. 2017). The
evaluator may then be asked to prepare a written report and /or
to provide testimony about that evaluation and their expert
opinions. For example. in civil contexts, they may be asked
to evaluate a plaintiff who has alleged compensable injury as a
result of a traumatic event or series of events. In this example,
the evaluator may be asked to assess the individual's prior
level of functioning, the impact of the traumatic events, and
the extent of halm, or damages incurred as a result (Foote &
Lareau. 2013). Forensic evaluators may also be asked to de-
tennine the time at which an individual reasonably knew or
should have known about a connection between a traumatic
event or events and any alleged resulting injuries. In criminal
cases, forensic evaluators may be called upon to assess an
individual's state of mind at the time of an alleged offense
and to opine about the possible impact of traumatic events
on that person's state of mind. At sentencing hearings, foren-
sic psychologists could be asked to evaluate an individual's
history to identify any potential traumatic events that could be
used as mitigating factors.
In both civil and criminal matters, psychological experts
may also be retained to provide scientific framework testimo-
ny about relevant psychological issues without having evalu-
ated an individual client. This is often referred to as providing
"general scientific testimony" about topics within an individ-
ual's general area of scientific expertise. For example, an ex-
pert witness who has not performed an evaluation of an indi-
vidual may be asked to assist the trier of fact by presenting
scientific data pertaining to issues such as the prevalence of
trauma, the psychological and physical consequences of trau-
ma. traumatic memory. dissociation, grooming behavior, or
issues related to predictions of risk and/or dangerousness
(Brand et al.. 2016; Frankel. 2009). They may also provide
valuable information about ways in which an individual's ex-
periences of traumatic events may influence their participation
with the legal system or may influence the ways in which they
tell their story. The role of the evaluating expert and the expert
providing scientific framework testimony is to provide inde-
pendent scientific information about specific topics to the trier
of fact that fulls within an area of the witness's demonstrated
area of expertise (American Psychological Association.
(APA). 2013; Melton et al., 2018).
In other instances, forensic psychologists are hired as con-
sultants to work with attorneys as part of their legal team, and
in those circumstances. there is no expectation that the psy-
chologist will conduct an evaluation or provide expert testi-
mony. Rather, the psychologist works to assist the attorneys
with their presentation and execution of their client's case.
(Datenberg et al.. 2017). They may be called upon to assist
the attorney with understanding the scientific literature related
to trauma exposure or to help the attorney to make sense of a
traumatized individual's behaviors. Irrespective of the role the
4;3 Springer
forensic psychologist has in a particular matter, it is critical
that they adhere to ethical principles and standards of practice.
They must be prepared to respond professionally to the pro-
fessional challenges that may arise in the context of a forensic
evaluation generally and a forensic evaluation involving trau-
ma, complex trauma. and/or dissociation more specifically.
Ethical and Professional Considerations
When working as forensic psychologists. as in all areas of
professional work, psychologists are expected to conform
their behavior to the APA Ethics Code, the most recent ver-
sion of which was developed in 2002 and revised in 2010 and
2017 (American Psychological Association [APA). 2017).
While the APA Ethics Code applies to all psychology special-
ty areas, including Forensic Psychology (Bush. Connell, &
Denney, 2020). certain sections of the code may be relevant
for forensic practice, generally. and forensic assessment in-
volving complex trauma, more specifically. The Code is com-
posed of an Introduction, a Preamble. General Principles A-E,
and specific Ethical Standards. The Preamble and General
Principles of the Code, in contrast to the Standards. are aspi-
rational in nature. "Their intent is to guide and inspire psy-
chologists toward the very highest ethical ideals of the profes-
sion- (APA. 2017. p. 3). The General Principles are not meant
to be obligatory in nature but rather provide an overall context
for ethical behavior. The second section of the Code consists
of specific standards for ethical behavior which are "enforce-
able rules for conduct as psychologists" (APA. 2017, p. 3).
In addition to the APA Ethics Code. Forensic Psychologists
can seek guidance from the APA Specialty Guidelines for
Forensic Practice (APA. 2013). These guidelines were original-
ly developed and published in 1991 and have been revised and
updated along with continuing developments in the field (APA.
1991. 2013). The Guidelines specifically state 'The goals of
these Specialty Guidelines for Forensic Psychology ('the
Guidelines') are to improve the quality of forensic psycholog-
ical services: enhance the practice of forensic psychology; en-
courage a high level of quality in professional practice: and
encourage forensic practitioners to acknowledge and respect
the rights of those they serve" (APA. 2013. p. II). Although
the Guidelines are informed by the APA Ethics Code, they are
advisory in nature. and are aspirational in intent. They are not
meant to be used as standards, nor are they intended to be
mandatory or exhaustive.
In addition to the APA Ethics Code and Specialty
Guidelines for Forensic Psychology, forensic psychologists
should also take into account the information, guidelines.
and standards that have been developed, adopted. or endorsed
by scientific and professional organizations within their areas
of specialization (Bush et al.. 2020). For example. within the
areas of forensic assessment of complex trauma, forensic

psychologists should be thoroughly familiar with the relevant
guidelines related to complex trauma and PTSD (Cloitre et al..
2012; International Society for the Study of Trauma and
Dissociation [1SSTD], 2011).
Many of the ethical issues inherent in a forensic evaluation
involving complex trauma and dissociation are common to
forensic psychological practice. In the following sections.
these ethical challenges and professional considerations and
the specific applicable sections of the APA Ethics Code and
the corresponding section of the Specialty Guidelines will be
reviewed. Wherever appropriate, specific applications to the
forensic assessment of complex trauma and dissociation will
be highlighted and explored.
Competence
When initially contacted by an attorney, the forensic psychol-
ogist must clarify the referral question to determine if the
questions asked fall within the evaluator's areas of expertise
and if an evaluation is likely to be able to determine the an-
swers to the questions posed. When undertaking an examina-
tion, it is incumbent upon the evaluator to ensure they have the
requisite skills, training, and level of competence to conduct
the evaluation and provide answers to the relevant psycho-
legal questions. Standard 2.01 (a) of the APA Ethics Code
states "Psychologists provide services, teach, and conduct re-
search with populations and in areas only within the bound-
aries of their competence, based on their education, training.
supervised experience, consultation. study. or professional ex-
perience" (APA. 2017). Guideline 2.01 of the Specialty
Guidelines similarly emphasizes the need for assessing one's
competence:
When determining one's competence to provide ser-
vices in a particular matter, forensic practitioners may
consider a variety of factors including the relative com-
plexity and specialized nature of the service, relevant
training and experience, the preparation and study they
are able to devote to the matter, and the opportunity for
consultation with a professional of established compe-
tence in the subject matter in question. (APA. 2013. p.
9).
Few mental health practitioners have received systematic
training in the assessment and treatment of trauma and its ef-
fects, and even fewer have received training in the area of
complex trauma and dissociation (Brand. 2016). Within the
specialized areas of trauma. complex trauma, and dissociation,
forensic psychologists should therefore seek out relevant train-
ing and supervision in the area of trauma psychology and have
expertise in the psychological assessment of complex trauma.
dissociation. and its effects as well as training and expertise in
the area of forensic psychology more generally (Brand. 2016;
Brand, Schielke. & Brains, 2017a: Dalenberg et al.. 2017).
Minimally, forensic psychologists engaged in this work will
need to be well versed in the scientific literature pertaining to
matters related to following content amts.
Prevalence and Incidence of Traumatic Stress Although the
incidence of traumatic events is high. the prevalence of
Posttraumatic Stress Disorder following a traumatic event is
relatively low. For example, Kilpatrick and colleagues found
that lifetime, past 12-month, and past 6-month prevalence of
PTSD was 8.3%. 4.7%. and 3.8% respectively (2013). In spite
of the relatively low incidence of PTSD among trauma survi-
vors, individuals who have experienced traumatic events are
likely to be overrepresented within forensic settings. For ex-
ample, Dalenberg et al. (2017) contacted two large law firms
in California in 2016 and found that the attorneys estimated
that over 80% of law suits included allegations of trauma.
Claims of emotional injury involving pain and suffering can
be raised in cases involving harassment, discrimination, rape
and sexual assault, personal injury, and disability. In these
cases, forensic psychologists are frequently called upon to
assess the impact and emotional damage resulting from a spe-
cific traumatic event or events and may need to opine about
the relative impact and sequelae of a number of traumatic
events that have occurred over the course of an individual's
lifetime. It is also important to understand that many of the
prevalence studies do not evaluate the frequency with which a
particular trauma happened. with many repotting the number
of categories rather than how many instances of a particular
trauma are present (see Bailey & Brown this issue).
Revictimization Given that childhood victimization has
been found to increase vulnerability for subsequent
rev ictimization (Classen, Palesh, & Agganval, 2005;
Widom, Czaja, & Dutton, 2008), forensic psychologists
may also be asked to assess the impact of traumatic
events that have occurred during adulthood when there
is also a prior history of other traumatic events (See
Brown, this issue, for further discussion.). They may
also need to address the sequelae of traumatic events
that have occurred during childhood and draw conclu-
sions about ways in which those traumatic events have
impacted the individual's life trajectory. Within the
criminal arena, forensic psychologists may be called up-
on to assess the impact of traumatic events on an indi-
vidual's state of mind at the time a crime occurred or to
help to explain their behavior during of following the
commission of an alleged criminal act. They may also
be asked to elaborate upon the presence of traumatic
events as mitigating factors to be taken into account
during sentencing. However, it is important to note that
much of the research has been completed on single-
incident trauma survivors and, therefore. may not well

represent individuals with repeated and/or ongoing trau-
ma exposure.
Complex Trauma Complex trauma is trauma involving harm
or abandonment by caregivers that occurs during a develop-
mentally vulnerable time period in an individual's life, espe-
cially during childhood, and that involves repetitive or
prolonged exposure to multiple traumatic stressors that is per-
petrated by caregivers over a prolonged period (Counois &
Ford. 2013). Exposure to this type of repeated trauma has been
shown to increase the likelihood of chronic and complex is-
sues. as well as significantly increased risk for further victim-
ization (Briere, Age. & Dietrich, 2016; Briere. Kaltman. &
Greene, 2008; Cloitre et al.. 2011: Courtois & Ford. 2013:
Herman, 1992). The proposed clinical syndrome describing
the constellation of difficulties experienced by adults who
were severely and repeatedly traumatized during childhood
is referred to as complex posttraumatic stress disorder
(cPTSD) (Courtois, 2008: Herman. 1992). A study of the
prevalence of complex PTSD as defined in the ICD-1 I found
prevalence rates of 0.6% in a representative community sam-
ple of US adults and 13% in a sample of US trauma exposed
military veterans (Wolf et al.. 2015).
Authors have conceptualized cPTSD as "involving patho-
logical dissociation; emotion dysregulation; somatization, and
altered core schemas about the self. relationships. and sustain-
ing beliefs (i.e.. morality, spirituality) in the aftermath of ex-
posure to traumatic interpersonal victimization" (van Dijke,
Ford. Frank. & van der Hart, 2015. p. 429). In their book on
the treatment of complex trauma. Courtois and Ford describe
the ways that complex trauma can result in major changes in
the following "seven key domains of an individual's develop-
ment: emotional regulation, memory. attention, and con-
sciousness, self-perception. perceptions of the perpetrator, re-
lationships with others, somatic symptoms and/or medical
problems, and sense of meaning in self, others, and the world"
(Courtois & Ford, 2013. In a literature review. Bailey and
Brand (2017) have further delineated the connections among
and between childhood traumatic events and the development
of enduring and severe sequake, including cPTSD and disso-
ciation. It is critical that forensic evaluators are aware of the
connection between trauma and dissociation because individ-
uals who have been diagnosed with cPTSD have been found
to experience trauma-related dissociation with more severity
and frequency than other populations (Brand, Schielke,
Brains. & DiComo. 2017b: Hyland, Shevlin, Fyvie, Cloitre,
& Karatzias. 2019).
Dissociation Dissociation is defined in the Diagnostic and
Statistical Manual of Mental Disorders (5th ed) as "a disrup-
tion and/or discontinuity in the normal integration of con-
sciousness, memory, identity, emotion, perception. body rep-
resentation, motor control, and behavior" (American
Springer
Psychiatric Association [APA], 2013, p. 291). It is often con-
ceptualized as an adaptive response designed to assist with
coping with trauma when physical escape is not possible
(Daknberg et al.. 2012). Although dissociation can be present
in a variety of clinical presentations. such as somatic, sub-
stance use, and psychotic disorders, it is most commonly re-
lated to trauma (Bailey, Boyer. & Brand, 2018: Lyssenko
et al., 2018). Dissociative disorders are more prevalent than
is commonly realized (See Bailey et al., 2018: Bailey &
Brand, 2017; Loewenstein. 2018). In his recent review.
Loewenstein (2018) found prevalence rates in the general
population ranging from 9.1 to 18.3% and prevalence rates
in clinical populations ranging from 4.6 to 48% across diverse
samples. Given that dissociation has been associated with a
range of functional impairments, as well as poor prognosis
and lower quality of life, it is particularly important that fo-
rensic evaluators involved in the assessment of trauma also
assess for dissociative symptoms (Brand. Schielke, & Brams,
2017a: Brand, Schielke, Brains, & DiComo, 2017b; Frankel,
2009). Assessment of complex trauma and dissociation in a
forensic context is a highly specialized area that requires ex-
pertise and training in both forensic psychology and trauma
psychology (Brand, 2016; Dalenberg et al., 2017).
Unfortunately. there is an overall lack of training and educa-
tion about trauma and dissociation, and the information is
often missing or inaccurate in many psychology textbooks
and training programs (Commis & Gold, 2009).
Cultural Competence Within the context of complex trauma
and cPTSD, issues pertaining to cultural competency and di-
versity must be attended to. particularly when the examiner
and evaluee are from different ethnic. socioeconomic, and/or
racial backgrounds. Principle E of the APA Ethics Code states
that:
Psychologists respect the dignity and worth of all peo-
ple.... Psychologists are aware of and respect cultural.
individual and role differences, including those based on
age. gender. gender identity. race, ethnicity. culture. na-
tional origin, religion, sexual orientation, disability, lan-
guage. and socioeconomic status, and consider these
factors when working with members of such groups.
Psychologists try to eliminate the effect on their work
of biases based on those factor... (APA, 2017, p. 4).
When evaluating a trauma survivor. the evaluator must also
attend to the ways in which that individual's cultural back-
ground is impacted by and impacts their experiences of the
alleged traumatic events and their interactions with the legal
system. As outlined by Brown. "Responding to trauma in a
culturally competent manner requires the psychotherapist to
understand how those added meanings that derive from con-
text and identity make each instance of trauma unique-
3502-027

Psychol. Inj and Law
(Brown, 2008. p. 4). In addition, various aspects of identity
can increase the likelihood of experiencing a traumatic event
and developing dissociative symptoms, particularly when an
individual identifies with a group that is relatively
disempowered within the dominant culture (Bailey et al.,
2018). Sensitivity and understanding are similarly required
in a forensic context, especially when there is a need to delin-
eate the specific impact and potential harm experienced as a
result of a traumatic event. Forensic psychologists must also
be aware of the power imbalance inherent in the relationship
between psychologist and evaluee and the ways in which that
power imbalance may impact the evaluee's behavior and state
of mind throughout the evaluation (Bailey et al., 2018)
Potential Role Conflicts
As described earlier, forensic psychologists can take on a va-
riety of roles when working within the legal system. including
evaluators, scientific framework experts providing general
scientific testimony. and consultants (Bush et al., 2020;
Gottlieb & Coleman 2012). While both types of testifying
experts, evaluators and scientific framework experts, speak
with attorneys and educate them about trauma and dissocia-
tion. their role is to provide independent and scientifically
informed information rather than advocacy. They should be
free of conflicts, and their opinions should not vary depending
upon the retaining party. In contrast a forensic psychologist
hired as a consultant may be retained to work with the legal
team to assist with their preparation and execution of their side
of the case, and there is no expectation that they will evaluate
the individual or provide testimony. In their capacity as foren-
sic consultants, they may work with the legal team to assist
them in their understanding of the psycho-legal issues and in
evaluating opposing expert depositions and reports. They may
also assist with legal strategy such as jury selection and prep-
aration of questions for deposition or direct or cross examina-
tion of witnesses. However, in this role, they do not provide
expert witness testimony or conduct evaluations. They are
considered a member of the legal advocacy team and do not
have the same expectations of independence and objectivity as
those providing expert testimony.
It is also critical to understand the distinctions between
clinical and forensic roles (Greenberg & Shuman, 1997). In
their influential article. Greenberg and Shuman enumerate ten
specific differences between clinical and forensic roles and
outline the numerous ethical difficulties and conflicts that in-
terfere with the ability of a clinician's ability to offer a forensic
opinion about their client. They highlight the necessity of
respecting these role differences and argue convincingly that
ignoring the role conflict jeopardizes both the therapeutic and
forensic endeavors for the patient as well as the rights of all
involved parties. Since this article's publication, there has also
been increased awareness of the ethical challenges presented
when forensic psychologists are asked to assume a clinical
role after the conclusion of the legal matter (Durgin 2019;
Melton et al.. 2018).
The importance of paying attention to potential role con-
flicts is similarly emphasized in APA Ethics Code Standard
3.05: "A psychologist refrains from entering into a multiple
relationship if the multiple relationship could reasonably be
expected to impair the psychologist's objectivity, competence.
or effectiveness in performing his or her functions as a psy-
chologist" (APA, 2017, p. 6). Similarly. Guideline 4.02 of the
Specialty Guidelines for Forensic Psychologists, states that "A
multiple relationship occurs when a forensic practitioner is in
a professional role with a person and, at the same time or at a
subsequent time, is in a different role with the same person"
(APA, 2013, p. 11). Guideline 4.02.01 further states that
"Providing forensic and therapeutic psychological services
to the same individual or closed related individuals involves
multiple relationships that may impair objectivity and/or cause
exploitation or other harm" (APA, 2013, p. 11).
When conducting any forensic evaluation, it is
essential to clarify the forensic psychologist's role in the
case and to determine "who is the client?' Unlike in clin-
ical settings, the person being evaluated in a forensic eval-
uation is not the client and is not the individual (or agen-
cy) to whom the psychologist owes the primary responsi-
bility. One must therefore first ascertain who the individ-
ual client is. In most civil evaluations, the client will be an
attorney, either for the defense or for the plaintiff.
However, the client could also be the court, in cases of
a court-ordered evaluation. At the time of the initial con-
tact with the retaining party, the forensic psychologist
should also determine who is involved in the case in order
to identify any potential conflicts (Foote & Lareau, 2013).
Ethics Code Standard 3.06 also clarifies obligations relat-
ed to conflict of interest and Standard 3.07 deals with
third-party requests for services (APA, 2017). Ensuring
that the role of the evaluator is clearly explained is even
more critical when evaluating a trauma survivor because
they frequently present difficulties with establishing trust,
particularly when a power differential is present (Courtois
and Ford 2009).
The interpersonal nature of complex trauma and the inher-
ent violations of trust and safety involved make it particularly
important that forensic psychologists evaluating complex
trauma and dissociation maintain clear and consistent bound-
aries and be wary of potential role conflicts in their work in
order to avoid doing further harm (Dalenberg et al., 2017). In
addition, the evaluator may need to clarify these critical dis-
tinctions between therapist and expert and the problems asso-
ciated with role conflicts with attorneys; in this writer's expe-
rience, attorneys often mistakenly believe that a therapist is the
"best" person to testify on behalf of their clients and benefit
from education about why these roles should not be blurred.

Legal and Jurisdictional Issues
In addition to identifying potential conflicts, psycholo-
gists need to be certain that they are able to practice in
the jurisdiction of the case. Licensure laws vary from
state to state, as do the requirements and permissions
related to temporary practice and the issue of practicing
forensic psychology in states where one is not licensed
is controversial (Heilbrun, Grisso, & Goldstein, 2009).
While many states do allow for limited temporary prac-
tice, a significant minority of states do not (Tucillo,
DeFilippis, Denney, & Dsurney, 2002). Standard
2.01(f) of the Ethics Code requires that "When assum-
ing forensic roles, psychologists are or become reason-
able familiar with the judicial or administrative rules
governing their roles" (APA, 2017, p. 5). Similarly,
Specialty Guideline 2.04 states:
Forensic practitioners recognize the importance of
obtaining a fundamental and reasonable level of knowl-
edge and understanding of the legal and professional
standards, laws. rules and precedents that govern their
participation in legal proceedings and that guide the im-
pact of their services on service recipients (APA, 2013,
P. 9).
Given the specialized nature of the forensic assessment of
trauma and dissociation, and the relative lack of training in this
area. psychologists who have that specialization may find
themselves contacted by attorneys from multiple jurisdictions.
It is therefore imperative that practicing forensic psychologists
are aware of the laws that apply in the jurisdictions in which
they intend to practice: however, information regarding tem-
porary practice can be vague and difficult to obtain (Shuman,
Cunningham. Connell, & Reid. 2003). It is therefore recom-
mended that the forensic evaluator contact the licensing board
of the state in which they intend to conduct an evaluation if
they are not licensed in that jurisdiction.
Fees and Engagement Agreement
The specific terms of the engagement agreement between the
hiring party (generally the attorney) and the psychologist
should be clearly delineated, ideally, in writing. Guideline
4.01 of the Specialty Guidelines states that:
At the initiation of any request for service, forensic prac-
titioners seek to clarify the nature of the relationship and
the services to be provided including the role of the
forensic practitioner... which person or entity is the
client; the probable uses of the services provided or in-
formation obtained; and any limitations to privacy, con-
fidentiality, or privilege (APA, 2013, p. II).
4!I Springer
Similarly. the Ethics Code Standard 3.07 states that "When
psychologists agree to provide services to a person or entity at
the request of a third patty. psychologists attempt to clarify at
the outset of the service the nature of the relationship withal
individuals or organizations involved" (APA, 2017. p. 6). The
engagement agreement should specifically address the com-
ponents of the evaluation, the fee agreement. and the
timeframe. Specialty Guidelines 5.01 and 5.02 specifically
deal with determination of fees and the need to clarify with
the client the likely cost of services, respectively (APA, 2013,
p. 12). The attorney should also be given guidance regarding
the anticipated total time required for the evaluation and for
writing a report. if needed.
Clients who are severely traumatized and experiencing
symptoms of dissociation may require a longer period
of time in order to adequately review their histories. In partic-
ular, clients who have experienced multiple episodes of trau-
ma beginning in early childhood will likely have more com-
plex and lengthier relevant background information that will
need to be reviewed and potentially documented in a report. In
addition, given the potentially triggering nature of the infor-
mation being reviewed, when possible. evaluees may benefit
from multiple. shorter appointments rather than one long
meeting for the evaluation. The complex nature of these eval-
uations can therefore add significantly to the time required for
an evaluation of complex trauma and dissociation, and this
will need to be explicitly discussed with the retaining party
prior to the evaluation.
Although the Ethics Code does not specifically refer to the
issue of payment on a contingent basis, Specialty Guideline
5.02 specifies that "Because of the threat to impartiality pre-
sented by acceptance of contingent fees and associated legal
prohibitions, forensic practitioners strive to avoid providing
professional services on the basis of contingent fees- (APA.
2013, p. 12).
The specifics of the engagement agreement should also
take into account the relevant legal requirements per the laws
in the specific jurisdiction. for example, federal law generally
requires production of a report as do evaluations conducted of
plaintiffs by forensic examiners retained by defense counsel
(Melton et al.. 2018).
Multiple Sources of Information
In keeping with Forensic Guideline 9.02 which states that
"Forensic practitioners ordinarily avoid relying solely on one
source of data, and corroborate important data whenever feasi-
ble" (APA. 2013, p. 15). a comprehensive forensic mental
health assessment (FMHA) requires multiple sources of infor-
mation (Heilbrun et al.. 2009). The psychologist should make it
clear to the retaining party at the outset of the evaluation that
they will require access to all documents pertaining to the case
and will need to conduct collateral interviews as pan of the

evaluation. The evaluator should not only take care to thor-
oughly review all documents provided but will also need to
request specific other documents. For example, when evaluat-
ing damages following a traumatic event or series of events. the
evaluator will need to review independent sources of infomta-
tion regarding the individuals' prior and current level of func-
tioning (Foote & Lareau. 2013). Such documentation may in-
clude. but is not limited to. school records, employment records
and performance evaluations, any prior psychological testing.
psychotherapy and medical records, arrest and prison records.
and possibly records related to involvement with foster care or
the state's department of children, youth, and families.
The evaluator will also need to identify individuals who
have potentially useful information with whom to conduct
collateral interviews. Specialty Guideline 8.03 states that
"Forensic practitioners strive to access information or records
from collateral sources with the consent of the relevant attor-
ney or the relevant party..." (APA. 2013. p. 14). In matters
involving the assessment of complex trauma, these individ-
uals will typically include those who have known the evaluee
over a long period of time, ideally before. during, and atter the
alleged incidents, as well as individuals who can provide in-
formation about the individuals previous and current levels of
functioning and performance (Foote & Lareau. 2013). These
individuals may include parents. siblings, other family mem-
bers, friends, coworkers, supervisors. therapists. and mentors.
among others. The individuals contacted for collateral inter-
views should be asked about their observations of the
evaluee's performance, functioning and symptoms, as well
as any other relevant information they are able to provide
(Foote & Lareau. 2013). However, particularly when
interviewing family members, it is also critical to understand
that some of these individuals may be perpetrators of past or
ongoing trauma, even if the evaluee is not willing to discuss
this with the examiner.
Informed Consent and Limits of Confidentiality
Once the evaluator has reviewed relevant documents and dis-
covery materials. upon meeting with the evaluee, it is essential
to obtain informed consent. The APA Ethics code 3.10(c)
specifies that psychologists must obtain informed consent
and that when services are court ordered or otherwise mandat-
ed. -psychologists inform the individual of the nature of the
anticipated services, including whether the services are court
ordered or mandated and any limits of confidentiality. before
proceeding." Standard 3.10(d) further specifies that consent
must be appropriately documented (APA. 2017, p. 7).
Standard 9.03 clarifies issues pertaining to the informed con-
sent process in assessments (APA, 2017. p. 13). Consent
should be obtained in writing and it is essential that the indi-
vidual being evaluated understand fully the process of the
evaluation, the role of the evaluator, the limits of
confidentiality, and the differences between a forensic evalu-
ation and treatment. The process should also delineate clearly
how the information will be utilized and to whom it will be
provided.
Standard 4 of the Ethics Code specifies the obligation of
psychologists to - take reasonable precautions to protect con-
fidential intonation- and to discuss with persons "the rele-
vant limits of confidentiality" and the "foreseeable uses of the
information generated" (APA. 2017. p. 7). This informed con-
sent process should also be repeated when conducting any
collateral interviews, as it is essential that any person with
whom the forensic evaluator interacts understand the purpose
of the interview and the limits of confidentiality.
When evaluating individuals who have experienced com-
plex trauma, and who may be exhibiting symptoms of disso-
ciation. it is particularly important to keep in mind that issues
related to informed consent may need to be addressed fre-
quently over the course of the evaluation. In addition, forensic
psychologists will need to take into account the pacing of the
evaluation, and ensure that the individual being evaluated
understands the nature of the questions that will be asked.
and the information that will be discussed. Further, the
evaluee should be prepared for the potential difficulty of the
evaluation, given the need to disclose trauma-related informa-
tion in a time-limited setting (flalenberg et al.. 2017).
Use of Appropriate Assessment Tools
The APA Ethics Code and Specialty Guidelines for Forensic
Psychology both include statements emphasizing the impor-
tance of using assessment tools that are appropriate for
assessing the matter at hand. Standard 9.01 emphasizes the
need to base opinions "on information and techniques suffi-
cient to substantiate their findings, and Standard 2.04 states
that "Psychologists' work is based upon established scientific
and professional knowledge of the discipline" (APA, 2017,
pp. 12, 09). Specialty Guideline 9.01 states that "Forensic
practitioners strive to utilize appropriate methods and proce-
dures in their work" (APA. 2013. p. 14), and Specialty
Guideline 10.02 states that "Forensic practitioners use assess-
ment procedures in the manner and for the purposes that are
appropriate in light of the research on or evidence of their
usefulness and proper application" (APA. 2013, p. 15).
In the case of the forensic assessment of complex trauma
and dissociation, the evaluator generally includes assessment
tools that are global measures of personality and potentially
cognitive functioning, as well as assessment tools that are
trauma specific (Brand, Schielke, Brams, & DiComo.
2017b: Brown. 2009; Dalenberg et al.. 2017). When using
general measures of personality, such as the PAI or the
MMPI, the psychologist must be well versed in the ways in
which trauma survivors respond to these measures. both on
validity and on clinical scales (Brand et al.. in press; Brand.

Psychol. Inj. and Law
Schielke, Brains, & DiComo. 20176; Brown. 2009: Eakin,
Weathers, Benson. Anderson. & Fundetburk. 2005; Lange,
Sullivan. & Scott, 2010). In accordance with Ethical
Standards 9.08 and 9.09, tests utilized should be current, and
if test scoring and interpretation services are utilized, the psy-
chologist must ensure that the interpretations are based upon
accurate data and norms that have been validated for use
with the population being evaluated (APA, 2017).
In addition to the use of general measures, a competent and
ethical forensic evaluation of trauma and dissociation will need
to include measures that specifically evaluate these
traumatic experiences and symptoms (Brand. Schielke,
Brains. & DiComo. 20176; Brown, 2009; Dalenberg et al.,
2017; Foote & Lareau. 2013; Frankel. 2009). Careful selection
of these trauma-specific measures will assist the evaluator in
using measures appropriately named and validated and those
that have demonstrated efficacy in evaluating trauma-related
symptomatology. Several of these, such as the TS1-2. also con-
tain validity measures. All instruments utilized should of course
be carefully and properly scored using appropriate norms.
In any forensic evaluation, where there may be external mo-
tivation to either exaggerate or minimize symptoms and psy-
chopathology. it is essential that the possibility of malingering
and overall response style both be carefully evaluated (Heilbrun
a al.. 2009; Melton et al.. 2018). There have been many articles
written about the assessment of malingering in trauma survi-
vors. and it is essential that the evaluator ensure that they are
using measures that have been appropriately named and vali-
dated in traumatized populations (Brand, Schielke, Brains. &
DiComo. 20176; Brand. Tursich, Tzall. & Loewenstein, 2014;
Brown, 2009; Rogers. Payne. Correa, Gillard. & Ross, 2009).
In addition, it is critical that forensic evaluators be aware of
ways in which the responses of complex trauma survivors can
appear to be exaggerated or feigned (Brown. 2009).
Record Keeping
Over the course of the evaluation. the evaluator should take
care to keep careful and accurate records. They will need to
make note of both what is observed throughout the evaluation
and what is reported by the evaluee. and these behavioral
observations should be accurately labelled as such (Brand,
Schielke. Brams, & DiComo. 20176: Dalenberg et al.. 2017;
Foote & Lareau. 2013: Heilbrun et al.. 2009; Melton et al.,
2018). In addition, it is critical that the evaluator retain a copy
of the engagement agreement with the attorney. carefully and
thoroughly document everything reviewed as part of the eval-
uation, and maintain a complete record of all testing and notes
taken dining the evaluation.
Brand and colleagues (Brand. Schielke. & Brains, 2017a)
and Brown (2009) provide guidance on the importance of
recording observations, particularly when assessing an indi-
vidual who has experienced complex trauma and dissociation.
cal Springer
This recommendation is consistent with the Ethics Code
Standard 6.01 regarding documentation of professional work
and records maintenance (APA, 2017. p. 9), and with
Specialty Guideline 10.06 which states that "Forensic practi-
tioners are encouraged to recognize the importance of
documenting all data they consider with enough detail and
quality to allow for reasonable judicial scrutiny and adequate
discover by all parties" (APA, 2013. p. 16). The evaluator will
also likely be required to provide a copy of their entire file to
the court and to the opposing attorneys.
Finally, when preparing and copying the record, attention
should be given to the maintenance of test security in accor-
dance with Ethics Code Standard 9.11 which specifies the
need for maintaining test security (APA, 2017). as well as
any copyright regulations pertaining to the test materials being
replicated.
Impact of Trauma Exposure on the Individual Being
Evaluated and the Evaluator
Additional areas for consideration that are specific to a foren-
sic evaluation involving the assessment of complex trauma
and dissociation include awareness of ways in which the
evaluee's individual history and experiences may impact them
throughout the course of the evaluation (Brand. Schielke. &
Brains. 2017a: Brand. Schielke. Brains. & DiComo. 20176;
Dalenberg et al.. 2017). For example, victims of complex
trauma may have significant difficulties with trust and with
feelings of shame. and may rely upon coping strategies such
as minimization, denial, or avoidance, that could significantly
impact their responses during the evaluation (Dalenberg et al..
2017).
The very nature of a forensic evaluation requires review of
a great deal of potentially traumatic information over a very
brief period. often only 1-2 days. This type of intense expo-
sure can be potentially overwhelming for the individual being
evaluated. As a result. the evaluator needs to pay attention to
the pacing of the evaluation and may need to offer frequent
breaks. In addition, the evaluator needs to pay attention to the
ways in which the individual being evaluated in responding to
questions and to the degree to which they are present and
grounded. They will need to work to help the individual being
evaluated remain within a window of affect tolerance, in order
to maximize the quality and accuracy of the data being gath-
ered (Brand. Schielke, & Brams, 2017a: Brand. Schielke.
Brains. & DiComo, 20176). This may seemingly put the fo-
rensic evaluator at odds with the role of the forensic evaluator
as an objective investigator, and the evaluator must take care
not to blur their role between forensic evaluator and treating
clinician. However, a competent forensic assessment will re-
quire use of both clinical and assessment skills, particularly
when evaluating a survivor of complex trauma. In many cir-
cumstances. the evaluee may be in therapy. and it is prudent to
3502-027

Psychol. Inj. and law
request that the therapist be "on call" and available to the
individual to assist them with issues related to safety. stabili-
zation. and distress tolerance during and following the evalu-
ation. In those circumstances where the evaluee is incarcerat-
ed, it is helpful to consider that overt distress can make some-
one a target and ensure that there is sufficient time to help the
individual regulate before returning to their cell.
It is also important to be aware of and to communicate with
the retaining attorney the ways that the trauma survivor's ex-
periences may impact their interactions with the legal system
as well as their response to the demands of the evaluation and
to testifying. For example. individuals with cPTSD may be
very hesitant to discuss or even to disclose their experiences to
their attorneys. and their use psychological defenses such as
minimization, compartmentalization. or denial may make it
more difficult for their attorneys to successfully advocate on
their behalf. In addition, difficulties with emotional regulation
and management of impulses. as well as engagement in high-
risk behaviors such as self-injury or substance use. may also
interfere with their interactions with the legal system (Brand.
Schielke, & Brams. 2017a; Brand, Schielke. Brams, &
DiComo, 20176). Judges and juries may have difficulty un-
derstanding the apparent lack of emotional response of an
individual who is testifying about their experiences, and the
testifying forensic expert will need to clearly explain the indi-
vidual's behavior in a way that helps the triers of fact make
sense of what they are seeing.
In addition to attending to the impact of the evaluation on
the individual being evaluated, a significant component of
competency for the forensic evaluation of complex trauma
involves an awareness of how the demands and content of
the evaluation will impact the evaluator. Standard 2.06(a)
and 2.06(6) of the Ethics Code state that psychologists should
not initiate professional activities when they know or should
know that their personal problems will interfere with perfor-
mance and that when experiencing personal problems with the
potential to interfere with competency. they - take appropriate
measures such as obtaining professional consultation or assis-
tance and determine whether they should limit suspend, or
terminate their work-related duties" (APA. 2017, p. 5).
The nature of a forensic assessment of complex trauma and
its effects is such that the evaluator will be exposed to explicit
details about traumatic events and their effects in a relatively
brief period of time. In addition, the evaluator will not have the
benefits of eliciting the information in the context of a thera-
peutic relationship that occurs over time, which may increase
vulnerability to vicarious traumatization. Vicarious traumati-
zation. which is distinct from burnout and compassion fatigue.
can produce in the evaluator (or therapist) the same symptoms
experienced by the trauma survivor (Pearlman & Saakvitne,
1995: Saakvitne & Pearlman. 1996). Similarly. Dalenberg
(2000) addresses the impact of countertransference on the
therapist's ability to hear and understand what the trauma
survivor is trying to communicate. Considering the risks of
vicarious traumatization and their potential negative impact on
the psychologist and on the forensic evaluation, it is impera-
tive that the forensic evaluator engage in self-care. Clinician
self-care can include things such as diet, exercise, sleep, and
time off, as well as consultation and personal therapy
(Frankel, 2017: Saakvitne & Pearlman. 1996).
Report Writing and Testimony
Following the completion of the evaluation, the forensic psy-
chologist will typically provide feedback to the retaining party
and may then be required or asked to prepare a written report.
The report should carefully describe the assessment process
and the bases for the conclusions made. As highlighted by
Brand and colleagues (Brand, Schielke. & Brains. 2017a;
Brand, Schielke. Brains, & DiComo. 20176), in the context
of the forensic assessment of complex trauma and dissocia-
tion. it is particularly important that the forensic psychologist
be prepared to present accurate information in a manner that is
both readily comprehensible and evidence-based. The psy-
chologist should also be prepared to dispel myths and correct
mis-information, and to present all information in a scientifi-
cally informed manner.
In accordance with Ethical Standard 9.01(a)"Psychologists
base the opinions contained in their recommendations. re-
ports. and diagnostic or evaluative statements, including fo-
rensic testimony on information and techniques sufficient to
substantiate their findings" (APA, 2017. pp. 12-13). The eval-
uator should be certain to limit their conclusions to those re-
sults supported by the evaluation, and not go beyond the data
when explaining assessment results. As specified in Specialty
Guideline 11.02. care should also be taken to carefully "dis-
tinguish observations, inferences, and conclusions. Forensic
practitioners are encouraged to explain the relationship be-
tween their expert opinions and the legal issues and facts of
the case at hand" (APA. 2013. p. 16).
The evaluator may also experience pressure from the
retaining attorney to add or to withhold statements that the
attorney sees as potentially damaging or disadvantageous to
their client. This is especially true when the plaintiff has a long
and extensive history of complex trauma, and the attorney is
concerned that discussion of the individual's past trauma
could be harmful to the case. It is critical that the forensic
psychologist make it clear to the attorney that all relevant
history will need to be explored and disclosed. and that the
psychologist's role is to provide an independent evaluation,
not an advocacy report The psychologist should be guided by
the Ethical principle B of Fidelity and Responsibility as well
as Principle C: Integrity in adhering to the standard 5.01 re-
gaiding the avoidance of false or deceptive statements (APA,
2017). In addition, Specialty Guidelines 11.01 and 11.04 pro-
vide guidance regarding accuracy. fairness and avoidance of

Association, 2013).
Conclusions
This ankle has highlighted key ethical and professional consid-
erations in a forensic psychological evaluation generally and
more specifically in the assessment of complex trauma and dis-
sociation. In particular. the recognition of trauma psychology and
forensic psychology as specialized areas of practice has been
emphasized. Therefore, forensic practitioners who wish to eval-
uate victims of complex trauma and trauma specialists who wish
to become involved with forensic practice both will require spe-
cialized training. education, and professional consultation. as
well as ongoing continuing education in order to maintain the
requisite competencies. Forensic practitioners need to remain
aware of the relevant laws and regulations governing the juris-
dictions in which they intend to practice and remain aware of
potential role conflicts. In addition the need for cultural compe-
tency as well as an ongoing awareness of ways that exposure to
trauma will impact the individual being evaluated and their par-
ticipation in the legal system as well as the forensic psychologist
are essential. Forensic psychologists should rely upon evidence-
based and trauma-informed assessment tools and make use of
multiple data sources when conducting evaluations. Knowledge
and comfort with the appropriate use of measures specific to
trauma and dissociation as well as awareness of the ways in
which complex trauma survivors that respond to broad-based
measures are also essential. An evaluator who attends to these
ethical and professional considerations can contribute greatly to
the field of forensic psychology. As concluded by Dalenberg
et al.. 'Taking into account the devastating consequences that
trauma can produce. as well as the resilience of the human spirit
the forensic evaluator can help the court come to a just and
balanced solution in civil and criminal matters- (2017. p. 556).
