This descriptive cross-sectional study aimed to assess the quality of work life (QWL) and investigate the relationships between personal characteristics, organizational climate, organizational support, and overall QWL among personnel working in sub-district health promoting hospitals (SHPH) in Nakhon Pathom province. A total of 297 persons (96.12% response rate), who have worked in SHPH for at least six months were included in this study. Data were collected from July 17 to August 31, 2023, using a self-administered questionnaire. Descriptive statistics, chi-square tests, Spearman’s rank correlation, and multiple linear regression were employed for data analysis, with a significance level set at 0.05. The results showed that the QWL was at a high level (Mean = 3.82, S.D. = 0.41). Social support (r = 0.746, p < 0.001) and organizational climate (r = 0.724, p < 0.001) were significantly associated with QWL. However, no significant association was found between personal characteristics and QWL. Social support and organizational climate were significant predictors of the QWL, jointly accounting for 66.9% of the variance in QWL (R2 adj = 0.669).The SHPH directors and public health administrators should focus on improving the organizational climate and social support through clear and practical policies to enhance the quality of working life among personnel.application/pdfengผลงานนี้เป็นลิขสิทธิ์ของมหาวิทยาลัยมหิดล ขอสงวนไว้สำหรับเพื่อการศึกษาเท่านั้น ต้องอ้างอิงแหล่งที่มา ห้ามดัดแปลงเนื้อหา และห้ามนำไปใช้เพื่อการค้าQuality of working lifeSocial supportOrganizational climateSub-district health promoting hospitalPersonnelResearch ArticleDepartment of Public Health Administration Faculty of Public Health Mahidol UniversityDepartment of Biostatistics Faculty of Public Health Mahidol UniversityDepartment of Family Health Faculty of Public Health Mahidol University
