Objective To examine the prevalence of compulsory citizenship behavior and turnover intentions among nurses and analyze the impact of compulsory citizenship behavior on turnover intention. Methods A survey was conducted with 341 practicing nurses. The Compulsory Citizenship Behavior Scale and the Turnover Intention Scale were used. Results The total score for nurses′ compulsory citizenship behavior was (20.65±2.87), while the total score for the turnover intention was (17.76±3.28). Compulsory citizenship behavior positively correlated significantly with turnover intention (P<0.05). Furthermore, compulsory citizenship behavior accounted for 30.9% of the variance in turnover intention. Conclusion The compulsory citizenship behavior and turnover intention levels among clinical nurses are notably high. To alleviate turnover intentions, managers should focus on reducing nurses′ compulsory citizenship behavior.
