Abstract
Background: The Cognitive Fusion Questionnaire (CFQ) has two versions (trait and state) that assess taking thoughts literally and thinking as likely to dominate behavior. Objectives: The current study modified original version of CFQ, which was translated previously in Iran and have used CFQ and modified version as known as the State Cognitive Fusion Questionnaire (SCFQ) for psychometrically evaluated these measures. Methods: A sample of individuals with mental disorders (N = 196) completed the CFQ, SCFQ, and other measures of interest. Results: One-factor models emerged for each measure, and each demonstrated good internal consistency. The CFQ versions were associated with psychopathology, experiential avoidance, and life satisfaction measures. Conclusions: These findings provide initial support for using these measures in research and clinical contexts to further our understanding of cognitive fusion in the Iranian mental disorder population.
