Abstract: Objective To explore influences of organizational support and career success on retention intention among male nurses and to provide evidences for clinical male nurses management.Methods With overall purposive sampling,610 clinical male nurses from 45 third-level grade A hospitals in Tianjin municipality were surveyed with Perceived Organizational Support Scale,Career Success Scale,and Retention Intention Scale.Data analysis and path analysis were carried out with SPSS 17.0 and AMOS 17.0.Results The retention intention score of the male nurses was 3.40±0.65.Correlation and regression analyses showed that all dimensions of organizational support and career success dimensions are significantly correlated with retention intention (r=-0.24-0.71,P<0.01).In addition,career success plays an intermediary effect between organizational support and retention intention among the male nurses(β=0.22-0.65,P<0.05).A well fitted model for the relationship between organizational support,career success and retention intention among the male nurses was established,with the indexes values of 2.904 for minimum value of the discrepancy (chi-square value) divided by degrees of freedom (CMIN/df),0.962 for adjusted goodness of fit index (AGFI),0.999 for goodness of fit index (GFI),0.970 for relative fit index (RFI),0.999 for incremental fit index (IFI),0.999 for normed fit index (NFI),0.980 for non-normed fit index (NNFI),0.005 for root mean squared residual (RMR),and 0.056 for root mean square error of approximation (RMSEA),respectively.Conclusion The model established could be used in studies about promoting retention intention of clinical male nurses.
