Identifying Subtypes of Women Survivors of Childhood Sexual Abuse: An MMPI-2 Cluster Analysis

This paper investigated subtypes of women childhood sexual abuse (CSA) survivors through a cluster analysis of their Minnesota Multiphasic Personality Inventory-2 (MMPI-2) clinical and validity scales. Participants were 117 women in outpatient treatment for CSA aftereffects at a university-affiliated community mental health center. Three well-fitting MMPI-2 cluster solutions were evaluated with discriminant analyses and MANOVAs; a 5-cluster solution was deemed optimal. Follow-up analyses demonstrated significant between-cluster differences on the Impact of Event Scale, Beck Depression Inventory, Dissociative Experiences Scale, and nearly all Symptom Checklist-90-Revised subscales. No differences emerged when comparing clusters on the Family Environment Scale and their CSA characteristics. Implications were considered for research and clinical practice, using the MMPI-2 with CSA survivors
