Strategic Family Therapy and Substance Abuse focuses on helping families address adolescent substance abuse issues. It is based on the work of Milton Erickson and developed further by Jay Haley. Brief Strategic Family Therapy involves 9-12 sessions to help families help themselves by preserving the family unit. It uses a strategic approach focused on the family system and identifying repetitive patterns of interaction rather than the content of discussions. The goal is to eliminate or reduce the adolescent's substance use and associated problem behaviors.
