Examining In-Session Group Leader Predictors of Adolescent Responsiveness to a Family-Based Universal Substance Use Prevention Program

Implementation challenges associated with low community effectiveness rates include low levels of client responsiveness to the intervention, less than ideal intervention fidelity, and low levels of provider quality of intervention delivery. The literature is mixed on how group leader fidelity/quality of delivery are associated with client responsiveness, and research on adolescents and ethnoracially diverse clients is particularly lacking. The current study examined group leader fidelity and quality of delivery as predictors of adolescent in-session group responsiveness to the first session of the Bridges intervention which is a universal, family-based, substance use prevention program delivered in Title I middle schools. Participants consisted of 325 adolescents across 30 intervention groups. Three separate observational coding teams coded group leader fidelity, group leader quality of delivery, and adolescent in-session group responsiveness to the program. Overall percentage of fidelity met was calculated. Next, two confirmatory factor analysis models were conducted on the responsiveness and quality of delivery data of session 1, and factor scores were extracted. Hierarchical linear regression was then conducted to predict adolescent responsiveness with group leader fidelity in step 1 and group leader quality of delivery in step 2. There were no significant associations between predictor variables and adolescent in-session group responsiveness. Findings suggest that group leader implementation constructs do not appear to account for a significant amount of the variance in adolescent group responsiveness during the first session. Future research should examine other variables that are relevant in influencing adolescent program engagement with larger sample sizes.
