Transformational Leadership, Organizational Commitment, OCB, and Performance Among Leprosy Control Managers: A SmartPLS Study
Abstract
This study examined the effects of transformational leadership and organizational commitment on the performance of leprosy program managers and tested Organizational Citizenship Behavior (OCB) as a mediating mechanism. A cross-sectional quantitative survey was conducted among 174 civil servants responsible for leprosy control programs across 17 district and city health offices in Southeast Sulawesi Province, Indonesia. Respondents were selected using proportionate simple random sampling. Data were collected using a structured five-point Likert-scale questionnaire and analyzed through Partial Least Squares Structural Equation Modeling (PLS-SEM) in SmartPLS 4 with 5,000 bootstrap subsamples. Transformational leadership had significant positive effects on employee performance (β = 0.236, p < 0.001) and OCB (β = 0.395, p < 0.001). Organizational commitment significantly predicted OCB (β = 0.537, p < 0.001) but had no significant direct effect on performance (β = 0.066, p = 0.206). OCB strongly predicted employee performance (β = 0.678, p < 0.001). The indirect effects confirmed that OCB partially mediated the relationship between transformational leadership and performance (β = 0.268, p < 0.001) and fully mediated the relationship between organizational commitment and performance (β = 0.364, p < 0.001). These findings identify OCB as a key behavioral mechanism through which transformational leadership and organizational commitment enhance the performance of leprosy program managers. The study provides practical implications for strengthening leadership practices, employee involvement, and extra-role behavior in public health organizations.
Keywords: Transformational leadership; organizational commitment; organizational citizenship behavior; employee performance; leprosy control; public health management; PLS-SEM.
