Psychometric Properties and Factorial Validity of the Dyadic Coping Inventory –the Persian Version

Abstract

This study seeks to investigate the factor structure, convergent validity, and reliability of the Persian version of the Dyadic Coping Inventory in an Iranian sample. The sample consisted of 816 participants were involved in a questionnaire study. Factor analysis was used to evaluate the psychometric properties of the Dyadic Coping Inventory. Results showed that internal consistency of this scale by using Cronbach’s Alpha was 0.84, and the internal consistency the subscales ranged from .64 to .81.The findings support the hypothesized five-factor structure (stress communication; emotion-focused dyadic coping; problem-focused dyadic coping; delegated dyadic coping; and negative dyadic coping) for the DCI and self- and other-perception. The psychometric properties of the DCI and its criterion validity with The Relationship Assessment Scale (RAS) were good. This study indicated satisfactory reliability and factor structure for the Persian version of the Dyadic Coping Inventory (DCI). Furthermore, DCI can be utilized for research and therapeutic purposes and it can inspire cross-cultural studies.
