Servant Leadership as a Driver of Team Cohesion and Conflict Mitigation: The Mediating Role of Psychological Safety

Team-based nursing care depends on cohesive relationships and minimal interpersonal conflict, yet the leadership practices that nurture these conditions in resource-constrained hospitals remain underexplored. Guided by servant-leadership theory and the concept of psychological safety, this study examined whether servant leadership (SL) enhances team cohesion (TC) and mitigates conflict (CM) among nurses in Sukkur, Pakistan and whether psychological safety (PS) mediates these effects. Proportionate stratified random sampling yielded 221 usable surveys from four public and private nursing institutions. Standardized scales for SL, PS, TC, and CM were analyzed with SmartPLS 4. The measurement model met reliability and validity criteria (α ≥ .85; AVE ≥ .60). Structural-model bootstrapping (5,000 resamples) showed SL exerted significant positive effects on TC (β = 0.45, p < .001) and CM (β = 0.34, p < .001) and strongly predicted PS (β = 0.52, p < .001). Psychological safety, in turn, related positively to TC (β = 0.30) and CM (β = 0.28), partially mediating the SL→TC (indirect β = 0.16) and SL→CM (indirect β = 0.15) paths. The model accounted for 50 % of the variance in cohesion and 43 % in conflict mitigation. Findings highlight servant leadership as a potent lever for fostering psychologically safe, harmonious nursing teams in low-resource settings. Leadership development initiatives that emphasize humility, empowerment, and follower well-being, coupled with practices that reinforce interpersonal safety, are recommended to improve teamwork and care quality.
