The sample consisted of 67 treatment providers from Parents United, 13 from private practice settings, 14 from prisons, and 4 from forensic mental health centers. These 98 providers ranged in age from 23 to 73, were largely full-time staff, and were 53 percent male and 47 percent female. About 79 percent held master's degrees or higher, most often in social work and psychology. Seventy-one percent had training or experience related to working with incest perpetrators. Group therapy was the most common treatment modality, with individual therapy and couple therapy also in extensive use. However, only about half of the providers used family therapy. Treatment providers in both community and institutional settings most often used a combination of treatment approaches, especially cognitive and behavioral therapy. Treatment length ranged from 2 to 5 years. Providers had many recommendations for improving treatment. Tables and 23 references.
