Reliability and Validity of the Cognition Checklist With Psychiatric Outpatients

The Cognition Checklist Anxiety scale (CCL-A) and Depression scale (CCL-D) were administered to psychiatric outpatients with panic disorder ( n = 51), major depression ( n = 44), or panic disorder and major depression ( n = 38). Both scales showed good internal consistency and moderately high levels of test-retest reliability. The scales generally had good convergent and discriminant validities, except that the CCL-D had a moderate-sized correlation with fear of negative evaluation, and the CCL-A was uncorrelated with fear of negative evaluation. The CCL-D showed good criterion-related validity, whereas the CCL-A was weaker in this regard. The CCL scales showed good factorial validity. In all, the results suggest the CCL scales generally have adequate psychometric properties for research purposes.
