Impact of Sense of Coherence on Work Ability: A Cross-sectional Study Among Croatian Nurses.

Introduction: Aimed at preparing the basis for planning evidence-based public health measures for preservation/ improvement of nurses' work ability (WA), the objective was to assess the relationship between WA and sense of coherence (SOC).

Methods: A cross-sectional study was conducted in 2018 among 713 nurses in Croatia. The association between poor WA index (PWAI) and SOC score (SOCS), adjusted for possible confounders, was determined by binary logistic regression analysis.

Results: The results of univariate logistic regression analysis showed a statistically significant negative association between SOCS and PWAI (OR=0.977, 95% CI 0.968 - 0.986, p<0.001). The results of multivariate logistic analysis showed an even stronger statistically significant negative association between SOCS and PWAI (OR=0.966, 95% CI 0.954 - 0.977, p<0.001) when adjusted for confounders.

Conclusions: The present study suggested SOC as an important health promoting resource of nurses which might offer protection regarding work-related stress. Weak SOC could be an important explanatory factor of poor WA. Accordingly, improving SOC by implementing health promotion measures in nurses' workplace could be an important way to increase the WA among nurses.
