job performance and psychological capital in a population of kindergarten teachers.Methods Based on the use of Job Satisfaction Questionnaire（JSQ）

Psychological Capital Questionnaire（PCQ）

and Job Performance Questionnaire（JPQ）

a total of 312 teachers from 16 kindergartens in Guizhou Province were surveyed.The mediation effect of psychological capital in the relationship between job satisfaction and job performance was assessed using sequential testing and the Bootstrap analysis

which was based on latent variable modeling.Results The overall PCQ score among these kindergarten teachers was 3.97±0.43

and the scores in dimensions of self-efficacy

resilience

hope

and optimism were3.95±0.47

3.93±0.56

3.92±0.48

and 4.06±0.50

respectively;their JSQ and JPQ scores were 3.98±0.70 and 3.70±0.58

respectively.Correlation analysis showed that

psychological capital and its dimensions were positively correlated with job performance（P<0.01）as well as job satisfaction（P<0.01）;job performance was also positively correlated with job satisfaction（P<0.01）.According to multiple stepwise regression analysis

psychological capital and job satisfaction had significant predictive effects on job performance（P<0.05）.The test for mediation effect revealed that

psychological capital had a partial mediation effect on the relationship between job satisfaction and job performance

accounting for 57.38% of the overall effect.Conclusion Among kindergarten teachers

job satisfaction not only directly affects job performance

but also has an indirect effect on job performance via psychological capital.
