BACKGROUND AND AIMS: Recognizing the ability to adapt coping mechanisms in response to the unique issues present in various Iranian societies underscores the importance of considering culture and religion when interacting with diverse groups of individuals. The objective of this study was to assess the reliability and validity of the fear of progression questionnaire-short form (FoP-Q-SF) in Iranian breast cancer patients. METHODS: In this methodological cross-sectional research design, 400 Iranian breast cancer patients completed the FoP-Q-SF in 2023. We assessed the characteristics, content, and both exploratory and confirmatory construct validity of the measures. To evaluate the reliability and construct validity of the FoP-Q-SF, we calculated Cronbachs α, McDonalds omega, and the Intraclass Correlation Coefficient. RESULTS: The average age of the patients was 49.18 (standard deviation = 16.14) years. The results of exploratory factor analysis revealed that a single-factor structure, specifically the self-efficacy scale, accounted for 65.045% of the total variance. The findings from the confirmatory factor analysis indicated a satisfactory model fit. The reliability analysis indicated that the internal consistency and stability of the measures were acceptable. CONCLUSION: The short Persian version of the FoP-Q-SF exhibits satisfactory validity and reliability. Thus, we recommend using this questionnaire to assess the fear of disease progression among breast cancer patients in Iran.
