The Effect of Organizational Culture on Mental Health and Well-Being in the Workplace

Abstract

This study explores the influence of organizational culture on employee mental health and well-being within workplace settings. Drawing on data from 19 employees across various industries in Nigeria, the study employed a mixed-methods approach, integrating quantitative surveys with validated instruments such as the Organizational Culture Assessment Instrument, WHO-5 Well-Being Index, and Depression, Anxiety, and Stress Scale. Descriptive and inferential analyses revealed a generally positive perception of organizational culture and moderate to high levels of well-being among participants. Correlation and regression results demonstrated a significant positive relationship between organizational culture and employee well-being (β = 0.52, p = 0.010), with culture explaining 41% of the variance in well-being outcomes. Although the direct relationship between organizational culture and mental health was not statistically significant, well-being was a strong negative predictor of mental health symptoms (β = -0.61, p < 0.001), accounting for 69% of the variance. The findings suggest that supportive organizational cultures foster well-being, which in turn contributes to improved mental health outcomes. Recommendations include enhancing leadership practices, promoting inclusive communication, and implementing structured well-being and mental health initiatives. Further research with larger and more diverse samples is recommended to validate and extend these insights.
