Results of a linear mixed model that includes fixed effects for stratification factors (disorder and site), as well as the baseline value of the outcome as a covariate. DF are (6, 149). Predictor refers to variable×time term; Moderator refers to the variable×treatment×time term. A statistically significant predictor term in a model where there was also a significant moderator term was not considered. Triple interactions are illustrated in Figures 2 and 3.
Statistically Significant effects are bolded.
Variable was square-root transformed for analysis.
Higher values of predictor are associated with more and faster improvement, regardless of treatment assignment. See Figure 1.
Not employed versus employed full or part time.
High school diploma or less versus some college or more.
