Dissociative Symptoms in Complex Posttraumatic Stress Disorder: A Systematic Review.

The 11th revision of the International Classification of Diseases (ICD-11) introduced Complex Posttraumatic Stress Disorder (CPTSD) as a sibling disorder to PTSD. Dissociative symptoms have been implicated in the severity of ICD-11 CPTSD; however, no reviews have investigated how dissociation has been measured in studies investigating CPTSD, nor the relationship between CPTSD and dissociation. This systematic review aimed to identify measures used to assess dissociative symptoms in studies that have assessed CPTSD according to ICD-11 criteria and to synthesize the relationship between these constructs. PsycINFO, PubMed, Scopus and Web of Science were searched on March 31, 2021. Seventeen articles met inclusion criteria. CPTSD was most frequently measured by a version of the International Trauma Questionnaire. Twelve measures were used to assess for dissociative symptoms, the most common being the Dissociative Symptoms Scale and the Dissociative Experiences Scale. The relationship between CPTSD and dissociative symptoms was moderate-to-strong, but inconsistently reported. Further research is needed to determine the most appropriate measure(s) of dissociation in CPTSD.

Dissociation training and symptom identification accuracy among Australian psychologists.

OBJECTIVE: Dissociation is a common but underrecognized sequelae of trauma exposure. We investigated Australian psychologists' training in dissociation, assessment practices, and accuracy in identifying dissociation symptoms. METHOD: Participants in this cross-sectional study of Australian psychologists (N = 280) were recruited through publicly available email addresses, graduate psychology programs, and social media. Participants estimated the percentages of their clients who had experienced trauma and had dissociative symptoms, their confidence in assessing and treating trauma and dissociation, their training in trauma and dissociation, and their dissociation screening practices. Participants were also asked to identify dissociation symptoms (per the Dissociative Experiences Scale-II and Somatic Dissociation Questionnaire-5) from a list of trauma-related symptoms. RESULTS: Although 99% of participants reported treating trauma-exposed clients, only 59.6% and 41.1% reported formal training in trauma or dissociation during their psychology qualification, respectively. One in five participants correctly identified all psychoform and somatoform symptoms as dissociation. Accurately identifying psychoform dissociation symptoms was associated with confidence in treating dissociation (p = .048) and having informal peer consultation on dissociation (p = .032). Accurately identifying somatoform dissociation was associated with confidence assessing (p = .006) and treating (p = .009) dissociation and having completed professional development on dissociation (p = .047). CONCLUSIONS: Most psychologists demonstrated inaccuracies in their knowledge of dissociation, which raises concern that dissociation may not be recognized in clinical practice and thus go untreated. Training on dissociation should be incorporated into psychology curricula, particularly at the graduate level, and accessible, cost-effective professional development programs for practicing clinicians are needed.
