Associations between workplace social capital, well-being, and work engagement in medical residents: a multicenter cross-sectional study

Abstract Background Workplace social capital (WSC), a social resource available within work or occupational environments, has been identified as an important factor for employees’ health in fields other than medical education. However, little is known about whether WSC is associated with well-being and work engagement among medical residents. The aim of this study was to examine the relationships between WSC, well-being, and work engagement specifically among medical residents. Methods This cross-sectional study was conducted at 32 hospitals in Japan, assessing WSC with the Japanese medical resident version of the Workplace Social Capital (JMR-WSC) scale. Well-being and work engagement were measured as the primary and secondary outcomes using the Subjective Well-Being Scale and the Japanese version of the Utrecht Work Engagement Scale. Results We analyzed data from 276 residents. Adjusting for possible confounders, the JMR-WSC Scale scores were associated with well-being in a dose-dependent manner (adjusted mean difference 6.55, 95% CI 4.96–8.15 for the WSC highest score quartile, compared with the lowest score quartile). The WSC Scale scores demonstrated a dose-dependent association with work engagement (adjusted mean difference 15.12, 95% CI 11.66–18.57 for the WSC highest score quartile, compared with the lowest score quartile). Conclusions This study showed that WSC was linked to enhanced well-being and work engagement among residents. Our findings offer insights for developing interventions to prevent resident burnout and create an environment conducive to residents’ well-being and engagement.
