Bridging Leadership Competency Gaps and Staff Nurses’ Turnover Intention: Dual-Rater Study in Saudi Tertiary Hospitals

<b>Background</b>: Nurse-manager competencies shape workforce stability, yet role-based perception gaps between managers and staff may influence staff nurses' turnover cognitions. <b>Objectives</b>: To (1) compare nurse managers' self-ratings with staff nurses' ratings of the same managers on the Nurse Manager Competency Inventory (NMCI); (2) compare both groups' perceptions of staff nurses' turnover intention (EMTIS); (3) examine domain-specific links between perceived competencies and perceived turnover intention; and (4) explore demographic influences (age, education, experience) on these perceptions. <b>Methods</b>: Cross-sectional dual-rater study with 225 staff nurses and 171 nurse managers in two tertiary hospitals in Saudi Arabia. Data were collected from August to November 2024. Managers completed NMCI self-ratings, and staff nurses rated their managers on the same NMCI domains; both groups rated staff nurses' turnover intention using EMTIS. Between-group differences were tested with one-way ANOVA (two-tailed α = 0.05), and associations were examined with Pearson's r (95% CIs). <b>Findings</b>: Managers consistently rated themselves higher than staff rated them across all nine NMCI domains; the largest descriptive gaps were in Promoting Staff Retention, Recruit Staff, Perform Supervisory Responsibilities, and Facilitate Staff Development (e.g., overall NMCI: managers M = 3.67, SD = 0.61 vs. staff M = 3.04, SD = 0.74; F = 0.114, <i>p</i> = 0.73)with comparatively smaller divergence for Ensure Patient Safety and Quality. Managers and staff did not differ significantly on EMTIS (overall EMTIS: managers M = 3.16, SD = 1.28 vs. staff M = 3.00, SD = 1.15; F = 21.32, <i>p</i> = 0.173). Specific competency domains-retention, supervision, staff development, safety/quality leadership, and quality improvement-showed small inverse correlations with EMTIS facets (typical r ≈ -0.11 to -0.19; <i>p</i> < 0.05), whereas the global NMCI-overall EMTIS correlation was non-significant (r = -0.077, <i>p</i> = 0.124). Effect sizes were modest and should be interpreted cautiously. <b>Conclusions</b>: Actionable signals reside at the domain (micro-competency) level rather than in global leadership composites. Targeted, continuous, unit-embedded development in human- and development-focused competencies-tracked with dual-lens (manager-staff) measurement and linked to retention KPIs-may help nudge turnover cognitions downward. Key limitations include the cross-sectional, perception-based design and two-site setting. Findings nonetheless align with international workforce challenges and may be transferable to similar hospital contexts.
