Abstract:

Objective To understand the current job stability of space medical workers,explore the relationship between organizational commitment and job satisfaction in perceived organizational support and turnover intention,and provide theoretical basis for improving the working environment of space medical workers and improving the stability of space medical team in the future. Methods From January to March 2024,740 medical workers in the aerospace system of Beijing and Wenchang City of Hainan Province were selected as the research objects by the cluster sampling method.The organizational support,organizational commitment,turnover intention and job burnout scales were used as the research tools to qualitatively and qualitatively describe the organizational commitment,job satisfaction,job burnout and turnover intention of the respondents.The multiple linear regression model was used to analyze the influencing factors of turnover intention,and Bootstrap method was used to test the mediating effect. Results The total scores of scales in 740 aerospace medical workers in Beijing and Wenchang City of Hainan Province were:organizational commitment(91.70±15.69)points,job satisfaction(59.87±21.58)points,job burnout(35.03±9.97)points,and turnover intention(10.42±4.65)points.The predictive effects of organizational commitment,job satisfaction and job burnout on turnover intention of aerospace medical workers were statistically significant(all P<0.05).The job satisfaction and job burnout formed a chain mediating effect in the process of organizational commitment affecting turnover intention,the effect value was -0.029(95%CI:-0.065--0.007),and the contribution rate accounted for 31.52% of the total effect. Conclusions The organizational commitment of aerospace system medical workers has a significant negative predictive effect on turnover intention,in which job satisfaction and job burnout constitute a dual mediating path. The path analysis showed that the two variables not only have an independent mediating effect between organizational commitment and turnover intention,but also form a chain mediating model.

Key words: Aerospace system medical workers, Job satisfaction, Job burnout, Turnover intention, Organizational commitment, Mediating role
