p < .05.
In the second hierarchical regression analysis, the Big Five personality factors accounted for a significant incremental proportion of the variance in practitioner ratings of adherence over and above age and sex, R2change = .16, F(5, 96) = 3.07, p = .006. Openness to experience (β = .24, p = .01) and conscientiousness (β = .35, p < .001) were significant predictors of SIRAS scores, with positive associations obtained for both factors.
