Pathways to dissociation: intrafamilial versus extrafamilial trauma in juvenile delinquents.

Dissociation is postulated to occur as a function of particular types of child abuse or chronic abuse. Additionally, there is an ongoing controversy examining the perpetrator's relationship to the victim in the development of dissociation. In this study, reports of traumatic events experienced both in the family environment and in the community were used to examine the relationship between dissociative disorder as defined by DSM-IV (pathological dissociation), and dissociation as a defense mechanism. The first objective was to identify whether the site of the trauma or the quantity of trauma correlated more significantly with symptoms of dissociation. The second objective was to explore a potential correlation between topics that participants choose to disclose during a standardized Stress Inducing Speech Task (SIST), and symptoms of dissociation. The third objective was to examine the relationship between the age of occurrence, the duration of trauma, and symptoms of dissociation. Fifty-two delinquent juveniles completed measures (including the SCID-D, REM-71, CTQ, CTI, SIST) assessing traumatic experiences, psychopathological dissociation, and dissociation as defense mechanism. Blind raters scored the SIST for intrafamilial and extrafamilial trauma. The perpetrator's relationship to the victim, site of the trauma, quantity of the trauma, age of occurrence, and duration of the trauma were analyzed by descriptive statistics and Pearson partial correlations. Significant correlations were found between symptoms of pathological dissociation and intrafamilial trauma. Significant correlations were not found between extrafamilial trauma and pathological dissociation and dissociation as defense mechanism. All these correlations held constant the chronicity of traumas reported. The results obtained in this study through blind and independent assessment suggest that special trauma characteristics (i.e., childhood trauma perpetrated by a family member) rather than sheer cumulative effects of trauma may have greater implications for the development of pathological dissociation. The relationships to dissociation as a defense were much weaker.
