Individual-level positive psychological capital that enhances managers' transformational leadership effectiveness on nurse career success.

Comprehensive efforts to highlight managers' transformational leadership and staff nurses' positive psychological capital can enhance subjective career success, which in turn improve nurses' job performance and intention to stay. Nursing policymakers should value transformational leadership among managers so nurses can achieve their subjective goals. An organization-wide institutional system should be developed so nurses can receive support to strengthen their positivity. Future research should include interventions to foster managers' leadership and nurses' positive capital.
