McGain, B. & McKinzey, R. K., (1995). The efficacy of group treatment in sexually abused girls. Child Abuse & Neglect, 19, 1157-1169.

Examined the efficacy of outpatient, once-a-week group treatment for 30 sexually abused females (aged 9-12 yrs), using a pre-post, matched control/treatment design. Ss were within 1 yr of trauma and were screened for psychosis. The Quay Revised Behavior Problem Checklist (RBPC) and the Eyberg Child Behavior Inventory (ECBI) were used as dependent measures, and given 6 mo apart. Depending on the scale, and excepting the RBPC's Psychotic Behavior Scale, 60-100% of Ss had abnormal scores pretreatment, with no significant differences between the 2 groups. Significant treatment effects were found. After treatment, 0-33% of treated Ss had abnormal scores, while 60-100% of controls continued to have abnormal scores.
