The Role of Leadership in Moderating the Effect of Interprofessional Collaboration on Training Quality at Bali Mandara Eye Hospital

Abstract

This study examines the effects of interprofessional collaboration (IPC) and leadership on training quality and tests whether leadership moderates the IPC-training quality relationship at Bali Mandara Eye Hospital. A quantitative cross-sectional survey was conducted among health professionals and other health-related personnel. From a population of 163 employees, 116 respondents were selected using proportionate stratified random sampling. Data were collected through a structured five-point Likert-scale questionnaire and supported by documentation, observation, and interviews. Partial Least Squares-Structural Equation Modeling showed that IPC positively and significantly affected training quality (β = 0.455, t = 4.920, p < 0.001), while leadership also had a positive and significant direct effect (β = 0.434, t = 4.663, p < 0.001). The interaction between IPC and leadership was positive but not significant (β = 0.028, t = 0.613, p = 0.540). Leadership therefore functioned as a predictor moderator: it independently improved training quality but did not strengthen or weaken the effect of IPC. The findings indicate that hospitals should reinforce cross-professional partnership, cooperation, and coordination while improving leaders' individualized support and integrating leadership practices into interprofessional training design.
