Abstract
This paper reports on the 6-month follow-up outcomes of an effectiveness study testing a multiple family group (MFG) intervention for clinic-referred youth (aged 7-11) with disruptive behavior disorders (DBDs) and their families in socioeconomically disadvantaged families compared to services-as-usual (SAU) using a block comparison design. The settings were urban community-based outpatient mental health agencies. Clinic-based providers and family partner advocates facilitated the MFG intervention. Parent-report measures targeting child behavior, social skills, and impairment across functional domains (i.e., relationships with peers, parents, siblings, and academic progress) were assessed across four timepoints (baseline, mid-test, post-test, and 6-month follow-up) using mixed effects regression modeling. Compared to SAU participants, MFG participants reported significant improvement at 6-month follow-up in child behavior, impact of behavior on relationship with peers, and overall impairment/need for services. Findings indicate that MFG may provide longer-term benefits for youth with DBDs and their families in community-based settings. Implications within the context of a transforming healthcare system are discussed.
