Psychometric Properties of the Dutch Cognitive Avoidance Questionnaire.

Various psychological disorders, such as major depressive disorder and anxiety disorders, share cognitive avoidance as one of the main mechanisms underlying symptom severity and maintenance. A valid and reliable measure that covers a broad array of cognitive avoidance strategies is therefore instrumental, though currently greedily missing. The Questionnaire d'Évitement Cognitif (QEC) was developed as a comprehensive instrument measuring five cognitive avoidance strategies. The current study aimed to evaluate the psychometric properties of the Dutch Cognitive Avoidance Questionnaire (CAQ-NL) in three samples (N sample 1 = 607; N sample 2 = 357; N sample 3 = 448). Confirmatory factor analysis supported the hypothesized five-factor structure of the CAQ-NL. Reliability analysis showed good to excellent internal consistency for the CAQ-NL and its five subscales. Furthermore, Multi-Group CFA revealed that the CAQ-NL demonstrated configural and metric invariance across the three samples. Convergent validity of the CAQ-NL was supported by substantial correlations with brooding, with more cognitive avoidance being related to more brooding. In addition, cognitive avoidance was negatively associated with psychological well-being and positively with symptoms of depression and anxiety, which corroborates the instrument's concurrent validity. Moreover, the CAQ-NL was predictive of depressive symptoms six months later, supporting its predictive validity. In sum, results of the present study provide support for the validity and reliability of the CAQ-NL.
