Psychometric properties of the cognitive fusion questionnaire

The purpose of the present study was to examine psychometric properties of the Cognitive Fusion Questionnaire (CFQ) in Shahid Beheshti University of Medical Sciences students.
To this end, 324 university students from Shahid Beheshti University of Medical Sciences were selected via cluster sampling method and participated in the present study through complete cognitive fusion questionnaire (CFQ), believability of anxious feelings and thoughts questionnaire, acceptance and action questionnaire-II, social anxiety-acceptance and action questionnaire, social interaction anxiety scale, valued living questionnaire and quality of life. Factor analysis by principle component analysis method and convergent and divergent validity was conducted to examine the validity of the CFQ. To calculate the reliability of the CFQ, Cronbach’s alpha and test-retest reliability were used.
Results from factor analysis by principle component analysis method yielded one factor that explained 54.89% of the variance. Support for the convergent and divergent validity of the CFQ via its positive correlations with the believability of anxious feelings and thoughts questionnaire, acceptance and action questionnaire-II, social interaction anxiety scale, and negative correlations with social anxiety-acceptance and action questionnaire, valued living questionnaire and WHOQOL-BREF was obtained. The reliability of the CFQ via calculating Cronbach’s alpha and test-retest coefficients yielded 0.86 and 0.86, respectively.
The Iranian version of the CFQ has acceptable levels of validity and reliability in university students. The CFQ is a valid and reliable measure to be utilized in research investigations and therapeutic interventions.
