The adaptation of an evidence-based brief intervention for substance-using adolescents and their caregivers.

Objective: Adolescent substance use is prevalent and associated with additional risk behaviours. Research shows that evidence-based brief interventions with adolescents and their main caregiver may mitigate the progression of substance use. Method: We used the ADAPT-ITT framework to develop a needs-based, culturally-sensitive intervention. Five focus groups with adolescents (n = 30), three focus groups with separate main caregivers of adolescents who use substances (n = 21), key informant interviews and an expert meeting, were conducted. Results: Adolescents described the need to decrease risk behaviours, while adolescents and caregivers requested additional support. The core components of the original intervention were retained, with some additions. The newly adapted RAD-PAL intervention was viewed as acceptable. Conclusion: Despite apparent acceptability, we need to test feasibility and efficacy in a trial.
