Multidimensional Family Therapy

Multidimensional Family Therapy (MDFT) focuses on addressing the needs of adolescents and young adults with substance use, delinquency, mental health, and emotional problems. MDFT is an integrated therapy model that incorporates and supports parents, families, and community partners (e.g., child welfare, schools). MDFT seeks to enhance coping, problem solving, and communication skills; stabilize mental health issues; reduce youth substance use; and improve school achievement among adolescents and young adults. MDFT also aims to improve parenting skills, parental functioning, family communication, attachment, and to reduce parenting stress.

MDFT is rated as a supported practice because at least one study carried out in a usual care or practice setting achieved a rating of moderate or high on design and execution and demonstrated a sustained favorable effect of at least 6 months beyond the end of treatment on at least one target outcome.

Target Population

MDFT serves adolescents and young adults (9 to 26 years old) with substance use, delinquency, mental health, academic/vocational, and emotional problems. At least one parent/guardian or parental figure must also participate in treatment.

Program or Service Delivery and Implementation

Dosage

MDFT intensity varies based on the setting and severity of participants’ needs. The recommended dosage ranges from 1 to 3 weekly sessions over 3 to 6 months. Each session lasts approximately 45 to 90 minutes. Additional support is provided between sessions via text and phone, as well as at community meetings (e.g., school, court, child welfare). Session length and frequency are designed to decrease over time with the goal of reducing to one session per week for the last four to six weeks of treatment. Sessions are divided roughly proportionally among those held with the adolescent/young adult, parents, and families. Additionally, community sessions are held with schools and representatives of other key systems throughout treatment (e.g., child welfare, juvenile delinquency).

Location/Delivery Setting

Recommended Locations/Delivery Settings

MDFT can be delivered in diverse settings and systems of care including clinical offices, in-home, community settings, outpatient, intensive outpatient, inpatient and residential facilities, and schools. The model can also be integrated within non-clinical residential settings, such as boarding schools or detention centers.

Education, Certifications and Training

MDFT is delivered by therapists with master’s degrees in social work, counseling, marriage and family therapy, or related clinical fields. MDFT therapists may receive additional support from therapist assistants with bachelor’s degrees. To deliver services, therapists must participate in approximately 5 months of MDFT-specific training. This training includes three on-site trainings, weekly consultations, online education, video reviews and live supervision of the therapist’s work. Ongoing feedback of therapist adherence and competence is provided using rating systems and written tests. At the end of this training, therapists are eligible to receive an MDFT certification. Supervisor training lasts an additional 4 to 6 months. Therapists and supervisors must re-certify annually. MDFT training is delivered virtually through videoconferencing and in-person at the clinical site.

A basic introduction to MDFT with continuing education units (CEU) is available through a 2-day introductory workshop for agencies and clinicians not seeking full MDFT Certification Training.

There is also an MDFT Train-the-Trainer (TTT) program that includes intensive workshops, live and video review of trainer training, and support with consultation calls.
