A Naturalistic Study of Treatment Outcome for Patients with Dissociative Disorders

This study is based on archival data completed by 424 participants ranging in age from 13 to 68 who had received or who were receiving treatment for dissociative disorders with comorbid symptoms at various clinical settings in the United States. The participants completed measures describing their treatment and degree of relief for their symptoms. Seven separate regression analyses were conducted. In each analysis, 14 predictor (i.e., treatment) variables were entered simultaneously. The dependent variable in each analysis was a symptom cluster identified by factor analysis of the symptom checklist completed by participants. The results of this study identify the unique treatment variables that predict specific client outcomes and are consistent with extant research indicating that treatment improves client functioning.
