Validity of the Snyder's Adult Hope Scale (AHS) among Iranian Women with Breast Cancer

Background: Cancer has experienced an alarming growth in the last two decades and is considered a pressing health problem of modern life. This study investigated the validity of Snyder's Adult Hope Scale (AHS) in Iranian women with breast cancer. Methods: ۱۷۷ Iranian women with breast cancer were randomly selected for the present descriptive cross-sectional study. Participants completed a demographic questionnaire and the Persian version of Snyder's Adult Hope Scale (AHS), the DASS-۲۱. The psychometric properties of the AHS were examined using confirmatory factor analysis (CFA) and discriminant validity using analysis of the DASS-۲۱. Results: The results of CFA showed that the two-factor provided an excellent fit to the data. All items of the loadings delivered a significant factor. These results are acceptable because the factor loadings of all items were significant, and the factor load of all items other than item ۱ is higher than ۰.۵, indicating the model's optimal fit. There was a significant negative relationship between AHS and DASS-۲۱ scores for anxiety (r=-۰.۴۹), depression (r=-۰.۵۱), and stress (r=-۰.۴۷), indicating acceptable divergent validity. Conclusion: Snyder's Adult Hope Scale (AHS) can be used as a valid and appropriate tool in clinical and educational settings to assess the hope of women with breast cancer and prepare treatment and prevention programs.
