The Relationship Between Sense of Coherence and Occupational Burnout Among Psychiatric Nurses: A Cross-Sectional Study in Inpatient Psychiatric Wards in Poland.

Background: Sense of coherence constitutes a significant personal resource that underpins the harmonious professional functioning of nurses employed in psychiatric inpatient wards. It serves as a protective factor, enabling effective coping with the psychophysical burden arising from a demanding and stress-inducing work environment, while also supporting the maintenance of a high level of job satisfaction. Regular assessment of the sense of coherence among psychiatric nursing staff is essential for the early identification of individuals at risk of developing occupational burnout. The aim of the present study was to determine the relationship between the level of sense of coherence and the degree of occupational burnout among nurses working in inpatient psychiatric units. Methods: The study employed a cross-sectional design and utilized standardized psychometric instruments, including The Sense of Coherence Questionnaire (SOC-29) to assess the level of coherence, and the Maslach Burnout Inventory (MBI) to measure occupational burnout. Additionally, a self-developed questionnaire was used to collect sociodemographic data. The research was conducted in five psychiatric hospitals in Poland between January and June 2023. The sample consisted of 555 nurses (449 women and 106 men) employed in inpatient psychiatric wards. Statistical analyses included descriptive statistics, Pearson's correlation coefficients to examine relationships between variables, and multiple linear regression to identify predictors of burnout dimensions. Significance level set at p < 0.05. Results: The mean global sense of coherence score among psychiatric nurses was 124.68 (SD = 45.81), with manageability scoring highest among subscales (43.83, SD = 16.28). Average occupational burnout scores were emotional exhaustion 28.75 (SD = 16.39), depersonalization 13.55 (SD = 9.71), and reduced personal accomplishment 23.61 (SD = 11.11). Significant negative correlations were found between sense of coherence (and its components) and all burnout dimensions (p < 0.001). Manageability was the strongest predictor of lower emotional exhaustion (β = -0.73), depersonalization (β = -0.65), and reduced personal accomplishment (β = -0.65), while meaningfulness predicted depersonalization (β = 0.37, p = 0.012). These results indicate that higher sense of coherence, especially manageability, is linked to reduced burnout among psychiatric nurses. Conclusions: The study revealed significant negative associations between sense of coherence and all dimensions of occupational burnout, with manageability emerging as the strongest protective factor. Nurses with higher levels of sense of coherence reported lower emotional exhaustion, depersonalization, and reduced personal accomplishment. These findings highlight the importance of incorporating sense of coherence assessment into strategies for identifying individuals at increased risk of burnout.
