Evidence for the validity of the Clinical Perfectionism Questionnaire in a nonclinical population: more than just negative affectivity.

This study examined the validity of the Clinical Perfectionism Questionnaire (CPQ; Fairburn, Cooper, & Shafran, 2003) in a nonclinical sample of 61 men and 182 women. Consistent with expectations, we found that scores on the CPQ were positively associated with scores on common measures of maladjustment, namely, depressive symptoms, anxious symptoms, and stress. In addition, results from regression analyses indicated that the CPQ accounted for additional variance in each of the 3 indexes of maladjustment beyond what was accounted for by multidimensional perfectionism and negative affectivity. Accordingly, our findings provide promising support for the validity of the CPQ in a nonclinical population.
