Development of the End-of-Life Care Nursing Attitude Scale for Japanese Geriatrics.

This study aimed to develop an end-of-life (EOL) care nursing attitude scale for Japanese geriatric nurses (ELNAS-JG). The items of the ELNAS-JG were developed to cover important topics related to EOL care (eg, motivation for providing EOL care, pain and symptom management, and decision-making support care for older adults). Participants were 1663 nurses employed in 32 institutions across Japan. Of these, 1298 participants were analyzed. An exploratory factor analysis of the 26 scale items revealed a 3-factor solution describing the concepts of responsibility, willingness, and confidence: responsibility and willingness were captured in factor 1 (16 items), and confidence was split into factor 2 (6 items) and factor 3 (4 items) to capture individual and collaborative behaviors. The overall Cronbach α coefficient for the 26 items was 0.95, and the intraclass correlation coefficient was 0.83. Overall, the ELNAS-JG was confirmed to have good internal consistency, test-retest reliability, content validity, known-groups validity, and construct validity. It can comprehensively measure nurses' attitudes toward EOL care for older adults in any EOL setting. Furthermore, this scale can be used to evaluate educational programs aimed at improving care quality and encouraging related activities in facilities that provide EOL care.
