The self-efficacy variables were also tested in the same way. The only admissible model contained the self-efficacy variables at posttreatment and at 15 months. The model containing these variables was an excellent fit to the data (model chi-square = 61.51; df= 52; p > .10; CFI=.99, RMSEA=.05). Self-efficacy at 15 months was a significant predictor PDA slope and was predicted by PDA intercept. As with the IPA and AA variables, the relationships between Treatment and PDA slopes and intercepts disappeared when the self-efficacy variables were in the model.
