Despite advances in evidence-based treatments (EBTs), research suggests these interventions are not utilized in practice settings. This study examined implementation of multi-family psychoeducational psychotherapy (MF-PEP), an EBT for childhood mood disorders, in two outpatient community clinics. Fifteen community therapists facilitated MF-PEP. Twenty community clinicians referred 40 children ages 8–12 with mood disorders and their parents who participated in MF-PEP. Preliminary descriptive findings based on observations and self-report questionnaires demonstrated implementation outcomes of acceptability, adoption, appropriateness, feasibility, implementation cost, penetration, and sustainability of MF-PEP at these clinics. Parents also demonstrated significant improvement in knowledge of mood disorders posttreatment. Preliminary results support implementation of MF-PEP in practice settings and suggest community-based MF-PEP may be associated with improvement in clinical outcomes.
