Psychometric Properties of the Persian Version of Cognitive Fusion Questionnaire-Chronic Illness in Multiple Sclerosis

Cognitive fusion is a substantial variable of acceptance and commitment therapy (ACT). Recently, various instruments have been developed to assess cognitive fusion, including a version relevant to medical illness referred to as the Cognitive Fusion Questionnaire-Chronic Illness (CFQ-CI).

This study aimed to assess the validity and reliability of the Persian version of CFQ-CI in multiple sclerosis (MS) patients.

In a cross-sectional study, the Persian version of CFQ-CI and several other measures that assessed self-compassion, depression, and social anxiety symptoms were administered on 195 MS patients in Shiraz Emam Reza Clinic. Exploratory factor analysis (EFA), internal consistency, and convergent validity were used for data analysis.

EFA revealed a 1-factor model. The Cronbachα was 0.92. As to the convergent validity, CFQ-CI had positive associations with measures of depression and social anxiety and negative associations with self-compassion.

Overall, this research supports the psychometric properties of the Persian version of CFQ-CI.
