Moderating effects of interprofessional collaboration on the relationship between moral sensitivity and job satisfaction among nursing assistants: A cross-sectional study.

Objectives: This study aimed to examine the moderating effect of interprofessional collaboration (IPC) on the association between moral sensitivity and job satisfaction among nursing assistants (NAs) in Japan. Methods: A cross-sectional survey was conducted. We recruited 375 NAs using a convenient sampling method from 14 hospitals in Okinawa, Japan, from June to July 2024. Data were collected using a self-administered questionnaire including demographic and work-related variables, the 20-item short form of the Minnesota Satisfaction Questionnaire, the Japanese version of the Revised Moral Sensitivity Questionnaire, and the 24-item Revised Otsuka Interprofessional Work Competency Scale. Hierarchical multiple regression analysis and simple slope analysis were used to investigate moderating effects. Results: The mean scores for job satisfaction and IPC were 59.50 ± 10.86 and 52.75 ± 15.08, respectively. The mean scores for moral responsibility, moral strength, and sense of moral burden were 7.38 ± 1.49, 11.43 ± 2.85, and 16.60 ± 3.42, respectively. Job satisfaction was positively correlated with IPC ( Conclusions: A sense of moral burden may enhance job satisfaction when supported by strong IPC. Enhancing both moral sensitivity and IPC may improve job satisfaction among NAs and support patient-centered care in Japan's rapidly aging society.
