Abstract: The objective of this study is to explore the influence of psychological capital on job engagement, and the multiple mediating effects of control sense and job insecurity among teachers in Open University, by adopting psychological capital scale, sense of control scale, job insecurity scale and job involvement scale for an anonymous test. The results indicate that 1) psychological capital has a significant predictive effect on job involvement; 2)sense of control and insecurity have a partial mediating effect between psychological capital and job involvement; 3) sense of insecurity has a complete mediating effect between sense of control and job involvement; 4) psychological capital has a significant indirect effect on job engagement through sense of control and insecurity, while sense of control has a significant indirect effect on job engagement through sense of insecurity. The conclusion is thus made 1) sense of control and insecurity play a mediating role in the impact of psychological capital on work engagement; 2) psychological capital can directly affect work engagement, but also indirectly affect work engagement through sense of control and job insecurity. In view of such, suggestions are put forward that in the process of school management in open university 1) we should, on the one hand, improve teachers’ psychological capital, and on the other hand, adopt various strategies to enhance teachers’ autonomy and work initiative, so as to enhance teachers’ sense of self-control, strengthen teachers’ sense of job security, and thus promote work engagement.

Key words: teachers in open university, psychological capital, control sense of work, job involvement, job insecurity
