Attachment-Based Family Therapy
Attachment-Based Family Therapy (ABFT) is a mental health program designed to treat depression in adolescents and young adults. ABFT aims to repair trust between adolescents and their parent(s) and re-establish parents as a source of support for the adolescent. By promoting secure relationships (i.e., attachment) between an adolescent and their parents, ABFT aims to help adolescents regulate emotional distress and promote autonomy.
The ABFT model consists of five treatment tasks. In Task 1, the relational reframe task, the adolescent and parents meet with the therapist with the goal of shifting the focus from the adolescent’s behavior to improving family relationships. In Task 2, the adolescent alliance-building task, the adolescent meets with the therapist to assess what has damaged trust and impaired the adolescent’s attachment to their parents. In Task 3, the parent alliance-building task, one or both parents meet with the therapist to discuss how current stressors and the parents’ own attachment history affects their parenting. In Task 4, the repairing attachment task, the adolescent and parents meet with the therapist to discuss issues of trust, betrayal, and commitment. The adolescent describes unmet needs, and the therapist guides the parents on how to be supportive and empathetic. In Task 5, the promoting autonomy task, the family, which may include siblings and other supportive people in the adolescent’s life, meets with the therapist to practice problem-solving skills, such as handling peer conflicts. The family negotiates solutions to difficult day-to-day challenges that promote autonomy while maintaining attachment.
ABFT is rated as a promising practice because at least one study achieved a rating of moderate or high on study design and execution and demonstrated a favorable effect on a target outcome.

Target Population
ABFT is designed for adolescents and young adults with depression and their parent(s).
Dosage
Therapists deliver ABFT over 12–16 weeks. Sessions are 60–90 minutes each. Task 1 involves one session, Task 2 involves 2–4 sessions, Task 3 involves 2–3 sessions, Task 4 involves 1–3 sessions, and Task 5 involves 8–9 sessions.
Location/Delivery Setting
Recommended Locations/Delivery Settings
Therapists can deliver ABFT in person in outpatient, inpatient, and community settings, or online.

Education, Certifications and Training
Therapists must have at least a master’s degree in social work, mental health counseling, clinical or counseling psychology, or couples and family therapy. The ABFT manual recommends that therapists have basic knowledge of and experience with family therapy.
The ABFT program offers three levels of training, with the third level culminating in certification. To achieve Level I status, therapists must complete a 3-day introductory workshop available online or in person that provides an overview of ABFT’s model and its procedures and process. Once participants achieve Level I status, they can describe themselves as an ABFT Trained (not certified) Therapist and begin to apply ABFT to their current cases.
To become a Level II Trained ABFT Therapist, therapists must complete supervision and an additional 3-day advanced workshop, available online or in person. Supervision involves 22 sessions of 60-minute individual or group case consultation video-conferencing with an ABFT-certified consultant. At the 3-day advanced workshop, participants discuss therapist issues, learn about the use of emotion-deepening skills, role-play, and receive supervision from a certified ABFT trainer. Other actions required for Level II include presenting at least four cases, showing two video excerpts of their cases, and completing the ABFT exam with a score of 80% or higher.
To achieve Level III status and become an official ABFT Certified Therapist, therapists submit a minimum of 10 video recordings of ABFT sessions they have conducted to ABFT Certified Supervisors. Therapists must also provide a case write-up for each submission with self-reflective feedback on how they might have improved the sessions and self-ratings of each session’s adherence to ABFT interventions. ABFT Certified Supervisors review the recordings and provide in-depth written feedback, rate session recordings on adherence to ABFT interventions, and if needed they offer a 20-minute phone consultation.

Note: For the effect sizes and implied percentile effects reported in the table, a positive number favors the intervention group and a negative number favors the comparison group. Effect sizes and implied percentile effects were calculated by the Prevention Services Clearinghouse as described in the Handbook of Standards and Procedures, Version 1.0, Section 5.10.4 and may not align with effect sizes reported in individual publications. The Prevention Services Clearinghouse uses information reported in study documents and, when necessary, information provided by authors in response to author queries to assign study ratings and calculate effect sizes and statistical significance (see Section 7.3.2 in the Handbook of Standards and Procedures, Version 1.0). As a result, the effect sizes and statistical significance reported in the table may not align with the estimates as they are reported in study documents.
Only publications with eligible contrasts that met design and execution standards are included in the individual study findings table.
Full citations for the studies shown in the table are available in the "Studies Reviewed" section.
The participant characteristics display is an initial version. We encourage those interested in providing feedback to send suggestions to preventionservices@abtglobal.com.
The table below displays locations, the year, and participant demographics for studies that received moderate or high ratings on design and execution and that reported the information. Participant characteristics for studies with more than one intervention versus comparison group pair that received moderate or high ratings are shown separately in the table. Please note, the information presented here uses terminology directly from the study documents, when available. Studies that received moderate or high ratings on design and execution that did not include relevant participant demographic information would not be represented in this table.
