Treated 14 female sex offenders (SOFs) convicted of child sexual abuse in a 3-yr demonstration project in a state prison. Treatment included developing an effective group psychotherapy model, a sex education program, implosive sexually explicit sensitization programs for staff and inmates, a community aftercare program, and family and couple therapy. Ecological in orientation, the treatment program was designed to modify victim-perpetrator dynamics among inmates and between inmates and staff. Data collected were (1) pre- and postintervention psychological evaluations of the inmates and (2) outside evaluation of the treatment program. Data led to development of hypotheses such as (1) female SOFs differ from male SOFs in some characteristics, (2) female SOFs are developmentally delayed, and (3) traditional methods for working with SOFs appear to be inappropriate with females.
