Interventions to improve nurses' job satisfaction: A systematic review and meta-analysis.

The current nursing shortage and increased turnover intentions are proving to be a global problem. For this reason, it is imperative that nurse managers plan strategies to improve nurses´ job satisfaction. The effective interventions detected in this study are a first step for developing human resource strategies for healthcare organizations. These findings propose that extrinsic factors (e.g., salary and rewards) will never be as effective in maintaining job satisfaction as intrinsic factors (e.g., spiritual intelligence, professional identity, and awareness).
