This study aimed to assess the relationship between the Communication skill scale for Home-Visiting Staff (CHVS;Watanabe, Shimazaki, & Takenaka, 2021), psychosocial factors, and intention to leave by following the job demand-resource model (Bakker & Demerouti, 2007). CHVS consisting of two scales, CHVS-user (α=.96) and CHVS-coworker(α=.95), was newly developed to assess communication skills of home-visiting staff with users and co-workers due to a high demand for home-visiting services. A total of 432 home-visiting staffs (Female=212, M=49.43 years old, SD=12.11) answered the online questionnaires about social support from co-workers and supervisors, job satisfaction, job engagement, well-being, and stress. The results showed significant differences of CHVS in gender, age, and employment status but not regarding job experiences and taking communication classes. The path analysis conducted after calculating a partial correlation coefficient between CHVS and the variables demonstrated that the former influences job satisfaction through a mediating function of social support.The stepwise regression analysis showed that job satisfaction significantly influences the intention to leave. Finally, the importance of communication skills and social support is discussed to improve retention of home-visiting staff.
