AimsTo explore the impact of psychological empowerment on nurses' intent to stay in military hospitals as well as the mediating effects of the practice environment and burnout in this context.DesignThis study employed a cross‐sectional survey approach and followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines for reporting.MethodsA total of 1225 nurses from nine military hospitals were recruited via convenience sampling. Questionnaires were distributed and collected via the Questionnaire Star platform. The study variables, including psychological empowerment, the practice environment, burnout and intent to stay, were assessed via self‐report questionnaires. SPSS 23.0 software was used to conduct descriptive and correlation analyses. Additionally, PROCESS Model 6 was employed to examine the mediating effects.ResultsPsychological empowerment is positively associated with nurses' intent to stay. Mediation analysis revealed that the practice environment, burnout and the chain mediating effect of the practice environment and burnout accounted for 54.5%, 2.8% and 1.5% of the total effect respectively.ConclusionPsychological empowerment affects nurses' intent to stay not only directly but also indirectly via the practice environment and burnout.Implications for the ProfessionNursing managers may consider utilising psychological empowerment as a management strategy to enhance nurses' perceived practice environment, reduce burnout and ultimately increase nurses' intent to stay. This approach has the potential to lower turnover rates among nurses.Patient or Public ContributionQuestionnaires completed by nurses were used to explore the relationships among psychological empowerment, the practice environment, burnout and intent to stay in this context.
