Specifically, Bonferroni post-hoc comparisons revealed a significant difference (p < .001) between the average change scores of the internet tailored PDS (M = 0.12, 95% CI [0.08, 0.17]) versus CG conditions (M = 0.01, 95% CI [−0.03, 0.04]), and also (p = .03) between internet tailored and non-tailored PDS groups (M = 0.05, 95% CI [0.00, 0.09]).
The average change score at each time point was significantly different from baseline (p < .0001), with the average change score ranging from 8.4 to 19 (Fig. 5).
