Dissociative experiences of adolescents with borderline personality disorder: description and prediction

Aims: The first purpose of this study was to assess the severity of dissociative experiences reported by adolescent inpatients with borderline personality disorder (BPD). The second purpose was to compare the severity of their dissociative symptoms to those reported by a sample of adult inpatients with BPD. The third purpose of this study was to assess a range of clinically meaningful predictors of the severity of dissociation in adolescents and adults with BPD.

Methods: The Dissociative Experiences Scale (DES) was administered to a total of 89 hospitalized girls and boys aged 13-17 with BPD and 290 adult inpatients with BPD. Predictors of the severity of dissociation in adolescents and adults with BPD were assessed using the Revised Childhood Experiences Questionnaire (a semi-structured interview), the NEO, and the SCID I.

Results: Borderline adolescents and adults had non-significant differences on their overall DES scores and subscale scores. They also had a non-significant distribution of low, moderate, and high scores. In terms of multivariate predictors, neither temperament nor childhood adversity was a significant predictor of the severity of dissociative symptoms in adolescents. However, co-occurring eating disorders were found in multivariate analyses to be the only bivariate predictor to significantly predict this outcome. In adults with BPD, however, both the severity of childhood sexual abuse and co-occurring PTSD were significantly related to the severity of dissociative symptoms in multivariate analyses.

Conclusions: Taken together, the results of this study suggest that the severity of dissociation is not significantly different in adolescents and adults with BPD. However, the etiological factors differ substantially.
