Validity and Reliability of the Farsi Version of the Heartland Forgiveness Scale in Iranian Cardiovascular Patients.

A Farsi version of the Heartland Forgiveness Scale (HFS-F) for assessing forgiveness in Iranian cardiovascular patients was not available. This study aimed to determine the validity and reliability of the Farsi version of HFS in this population. In this methodological cross-sectional research design, 400 Iranian cardiovascular patients completed the HFS-F between October 2019 and January 2020. We assessed the characteristics, content, and both exploratory and confirmatory construct validity of the measures. To evaluate the reliability and construct validity of the HFS-F, we calculated Cronbach's alpha, McDonald's omega, and the Intraclass Correlation Coefficient. Three factors were identified following confirmatory and deterministic factor analyses. The extracted factors demonstrated satisfactory reliability, exceeding a threshold of 0.7. The HFS-F exhibited a robust level of validity and reliability, rendering it a suitable instrument for future research endeavors.
