Multisystemic Therapy for Youth With Problem Sexual Behaviors (MST-PSB) – Multisystemic Therapy for Youth with Problem Sexual Behaviors (MST–PSB) is an adaptation of MST aimed at adolescents who have committed sexual offenses and demonstrated other problem behaviors. MST–PSB is designed to reduce problem sexual behaviors, antisocial behaviors, and out-of-home placements. The program targets factors underlying problematic juvenile sexual behavior, primarily by addressing a youth’s socialization processes and interpersonal transactions. Program staff provides treatment within the adolescent’s natural environment—that is, where the youth lives. As a result, program staff members also work directly with the youth’s family and directly or indirectly with others in the youth’s community, such as peers, teachers, or probation officers. One goal of this work with the youth’s family is to empower the parents by providing them the skills and resources needed to raise their adolescent.
