Intended Outcomes:FFT is a phasic program with steps, which build upon each other. Each phase has a specific goal/outcome. The following are the phases and their associated goals:
- Engagement: Enhancing family members' perceptions of therapist responsiveness and credibility.
- Motivation: Creating a positive motivational context by decreasing family hostility, conflict, and blame while increasing hope and building balanced alliances with family members.
- Relational Assessment: Analyzing the patterns of interaction within the family to understand the relational "functions"—or the interpersonal motives behind individual family members' behaviors.
- Behavior Change: Reducing or eliminate adverse behaviors by improving family functioning and individual skill development. 5. Generalization: Extending the improvements made during the Behavior Change phase into multiple areas and planning for future challenges.
Continuum of Care:
Behavioral Health/Mental Health, Disruptive Behaviors, Substance Use
Significant and well-articulated attention was given to disparities in outcomes
FFT works primarily with 11 to 18-year-old youth who have been referred for behavioral or emotional problems by the juvenile justice, mental health, school or child welfare systems. Services are conducted in both clinic and home settings, and can also be provided in schools, child welfare facilities, probation and parole offices/aftercare systems and mental health facilities.
FFT’s recommendation is to use at least master’s level therapists unless extraordinary circumstances require the use of bachelor's level therapists. It is the responsibility of the provider to meet or exceed local licensure and certification requirements.

Rationale for Rating:
Most effective outcomes are in probation completion, decrease recidivism, reduction in use of illicit substances with court involved youth. The majority of studies either do not measure or do not show sustained behavioral change past an 8 month period. Most of the research supporting Functional Family Therapy in the other national databases was from 1970s-2000s.
