Abstract

This study tested the plausibility of a theoretical model of change for the Penn Resiliency Program (PRP), a cognitive-behavioral (CB) depression prevention program for adolescents. Middle school students (N = 697) were randomized to PRP, an assessment-only control condition (CON), or a placebo-control condition (PLA). Explanatory style and depressive symptoms were evaluated over 24 months of follow-up. Relative to both CON and PLA, there were significant indirect effects of PRP on 12-month levels of depressive symptoms through improvements in explanatory style in two of three participating schools. Within a third school, where PRP was not effective in targeting depressive symptoms (Gillham et al., 2007), there was no evidence of group differences in growth in explanatory style or indirect effects. When effective, PRP's CB training provides incremental value over non-specific components and there are indirect effects on depressive symptoms through improvements in explanatory style.

Keywords: depression; explanatory style; mediators; placebo-control; prevention.

Two-Stage Piecewise Parallel Process Model. This model tested the primary hypotheses that, in schools A and B, there would be indirect effects of PRP vs. CON (IND1) and PRP vs. PLA (IND2) on 12-month levels of depressive symptoms (“Intercept CDI”) through improvements in the rate of change in explanatory style from baseline through 12 months (“Initial Slope CPCN”). This model also tested competing hypotheses that, in schools A & B, there would be indirect effects of PRP vs. CON (IND3) and PRP vs. PLA (IND4) on 12-month levels of explanatory style (“Intercept CPCN”) through reductions in depressive symptoms (“Initial Slope CDI”). For simplicity, only parameter estimates that were part of the indirect effects are depicted here.
