NOTE: Models estimated with 1000 bootstrap replications and adjusted for all covariates in first-stage models. Percent change was calculated by taking (direct effect-total effect)/total effect, total effect of treatment on BPI: Boys b(SE): .271(.065); total effect of treatment on Distress: Boys b(SE): .140(.060); Girls b(SE): -.123(.060).
