Abstract
Introduction: The aim of this study was to examine the factor structure, reliability, and validity of the Persian version of the Unforgiveness Scale among Iranian university students. Method: The present study was applied in terms of its objective and employed a descriptive-correlational design for data collection. To this end, 450 students from Jundishapur University of Medical Sciences in Ahvaz were selected using a multistage cluster sampling method during the 2023–2024 academic year and responded to the Unforgiveness Scale. The factor structure of the scale was analyzed using exploratory and confirmatory factor analysis. Internal consistency was assessed through Cronbach’s alpha, and validity was examined using convergent and divergent validity methods, employing the Resentment Questionnaire and the Trait Forgiveness Scale, respectively. Results: All confirmatory factor analysis indices, including CFI, NFI, IFI, and TLI, indicated an acceptable and appropriate fit for the scale. The overall Cronbach’s alpha coefficient of the scale was 0.93, demonstrating high internal consistency. Statistically, all factor loadings were above 0.55 and significant at the 0.001 level. Pearson’s correlation between the total score of this scale and the Resentment Questionnaire was 0.65, while its correlation with the Trait Forgiveness Scale was -0.59, both significant at the 0.001 level, indicating satisfactory convergent and divergent validity. Conclusion: Given the satisfactory model fit, appropriate validity and reliability, and high credibility of the Unforgiveness Scale, it can be utilized for assessing and measuring interpersonal unforgiveness in the Iranian population.
