We then examined whether PFI efficacy was different across the BMI and WF conditions depending on individual and situational factors. In other words, we tested for moderation effects (i.e., differential efficacy of the PFI types by individual and situational factors). In addition to the six individual and situational factors, we examined baseline levels of HED and AP as potential moderators. All continuous variables were centered in order to avoid potential multicollinearity problems, and interaction terms were created with centered variables. We added each interaction term one at a time to the final multivariate model shown in Table 3.
