Multimodal Assessment of Dissociation in
Adolescents: Inpatients and Juvenile Sex Offenders
William N. Friedrich,
Paul N. Gerber,
and Dennis Franckowiak
Two samples of adolescents were studied to assess the validity of several measures
of dissociation. The ﬁrst sample included 70 males from a residential treatment
program for adolescent sex offenders (ASO). The second were 47 psychiatric inpa-
tients. Themeasures includedthe DSM-IVﬁeld trialquestionnaire forDissociative
Disorders ofChildhood,Child DissociativeChecklist,Adolescent-Dissociative Ex-
periences Schedule,Trauma Symptom Checklist for Children, and the Dissociation
Research scale. Ten of the 70 adolescent sex offender subjects (14.3%) were iden-
tiﬁed as meeting DSM-IV criteria for a Dissociation-spectrum disorder diagnosis
and two (4.2%) of the psychiatric patients. Between-groups analyses with the ASO
revealed signiﬁcant differences on the Child Dissociative Checklist and the Disso-
ciation Research Scale. Cumulative trauma did not differ signiﬁcantly between the
dissociative and nondissociative groups of ASO, but physical abuse was related to
a diagnosis of dissociation in this sample. The dissociation measures were highly
intercorrelated for both groups, and suggest that they measure a similar construct.
KEY WORDS: adolescent sex offenders; dissociation; multimodal screening; trauma.
Dissociation is a complex phenomenon that includes features of amnesia or
memory loss, absorption, and depersonalization (American Psychiatric Associa-
tion [APA], 1994). It is related to traumatic experiences and is thought to character-
ize a percentage of victims of childhood violence, including sexual abuse (Putnam,
1989). The literature on dissociation suggests that individuals with this disorder
have experienced more than the usual amount of trauma, and that it typically has
been chronic and overwhelming (Ogawa, Sroufe, Weinfeld, Carlson, & Egeland,
1997; Steinberg, 1995).
