Abstract:
|
Large treatment effects are difficult to find when evaluating the effects of substance abuse treatment modalities among adolescent clients. It is hypothesized that client heterogeneity could explain this in so far as the effects of treatment may be greatest for a subgroup of patients. Most analyses examining moderation effects of treatment focus on moderation by time-invariant characteristics of patients measured at baseline. However, most clients in substance abuse treatment experience multiple treatment episodes over time, and time-varying moderators of treatment effects (e.g., severity of substance use problems after different treatment episodes) may exist. We employ the structural nested mean model to estimate the causal effect of additional treatment on longitudinal substance use outcomes, and to identify possible time-varying moderators of these effects.
