Psychometric properties of the Persian version of Clinical Perfectionism Questionnaire: Findings from a clinical and non-clinical sample in Iran

Clinical perfectionism has been viewed as a transdiagnostic process for emotional disorders. The aim of the present study was to explore the structural, convergent, divergent, discriminative validity, and reliability of the Persian version of Clinical Perfectionism Questionnaire. A general population sample (n=384) and patients with Major Depressive Disorder (n=40), Social Anxiety Disorder (n=35), Obsessive Compulsive Disorder (n=39), and Eating Disorders (n=38) completed Clinical Perfectionism Questionnaire, Perfectionism Inventory, and Depression, Anxiety, Stress Scale-21. Confirmatory factor analysis showed that the two-factor model provides the best fit with data. These factors showed positive significant correlation with congruent subscales of Perfectionism Inventory. The Evaluative Concern factor had significant correlation with depression, anxiety and stress, while Personal Standards factor did not associate with these symptoms. These factors successfully distinguished clinical groups from general population. Internal consistency of CPQ was acceptable in both samples. Collectively, findings provided promising evidences for the validity and reliability of the Persian version of the Clinical Perfectionism Questionnaire in both general population and clinical group.
