Objective Home-visit nurses play a key role in supporting the spouses of terminal cancer patients and encouraging positive perspectives of the caregiving experience. This study aimed to develop a scale to support nurses in self-assessing their practice around this important role. Design Cross-sectional questionnaire study. Setting The Home Nursing Scale to Help Spousal Caregivers (HNS-HSC) questionnaire for self-assessment of home-visit nursing to spouses was developed based on interviews with spouses and literature reviews. Participants Overall, 1500 home-visit nurses nationwide who had experience in supporting spousal caregivers and their patients in the predeath and postdeath periods were approached for participation. Main outcome measure Planned exploratory and confirmatory factor analyses were used to assess the underlying dimensions of the HNS-HSC; Cronbach’s α was used to determine the reliability. The Japanese version of Frommelt Attitude Toward Care of the Dying Scale Form B (FAT-COD-B-J) and Grief Care scale were administered to assess convergent and discriminant validity. Results Exploratory and confirmatory factor analyses identified 26 items on five factors: ‘helping spouses plan their futures’ ‘helping caregivers alleviate any regrets regarding their care’, ‘understanding the bond between a couple’, ‘providing support for anticipatory grief’, and ‘addressing spousal caregivers’ emotions after their spouses’ deaths’. The final model showed acceptable goodness-of-fit indices. The Cronbach’s α for the entire scale was 0.949 and exceeded 0.822 for each factor. The correlation coefficient with the FAT-COD-B-J, which served as an external validation, was 0.35. The correlation coefficients for the three grief care scales were 0.64, 0.45 and 0.72, respectively. Conclusions This scale is a reliable and valid tool for visiting nurses to self-assess their knowledge, skills and practice around helping spousal caregivers. By using this scale, it is expected to change nursing practice in pursuit of improving quality of life of spouses.
