Development of a Japanese Benefit Finding scale (JBFS) for patients with cancer.

The primary aim of this study was to develop a scale to evaluate benefits for patients with cancer under treatment in Japan (the Japan Benefit Finding scale [JBFS]). The participants were 98 patients with cancer who completed the JBFS, which has 26 items, the General Health Questionnaire short version (GHQ 12). Factor analysis, structural equation modeling (SEM), and correlation analysis were performed. Three key domains were identified: ''Recognition of one's role in the family and priorities,'' ''Appreciation for life,'' and ''Faith.'' Validity was confirmed by SEM. There was a significant correlation between the JBFS and GHQ 12. The reliability and validity are adequate, and the JBFS shows that Japanese patients who found benefits in cancer were able to adjust to their disease.
