The psychosocial work environment factors are a key determinant of healthcare professionals' subjective well-being (SWB); however, the mechanisms through which these factors operate remain insufficiently understood. This study aimed to develop and validate a context-specific measurement instrument and to examine how psychosocial work-environment factors influence SWB, focusing on psychological mechanisms. A cross-sectional study was conducted among healthcare professionals (N = 333) in a Latvian inpatient healthcare institution. The sample was randomly split for exploratory (n = 140) and confirmatory (n = 193) factor analyses. Psychosocial work environment factors were assessed using an author-developed instrument grounded in the Job Demands-Resources (JD-R) model, while SWB was measured using the WHO-5 Well-Being Index. Structural equation modeling (SEM) with a robust estimator (WLSMV) was applied. The final measurement model demonstrated good fit (CFI = 0.979; TLI = 0.970; RMSEA = 0.059; SRMR = 0.055). Psychosocial work environment factors explained up to 40% of SWB variance. Organisational support and trust (β = 0.420, p < 0.001) and professional fulfilment (β = 0.311, p < 0.001) emerged as significant predictors. Job demands and other factors were not directly associated with SWB. Mediation analysis showed that professional fulfilment partially mediated the relationships between organisational support and trust (31.2%) and perceived professional value (42.3%) with SWB. Sociodemographic variables were not significant. These findings suggest that SWB among healthcare professionals is primarily shaped by psychosocial job resources. Professional fulfilment is a central mechanism linking work environment conditions to well-being. The validated instrument provides a robust tool for assessing psychosocial work environments.
