ABSTRACT

OBJECTIVE: To explore the effects of psychological capital on occupational stress of employees in labor-intensive electronic enterprises. METHODS: A total of 1 723 employees in 5 labor-intensive electronic enterprises were selected as study subjects by cluster sampling method. The Psychological Capital Questionnaire and Simple Job Stress Questionnaire were used to investigate their psychological capital and job demand-control( JDC) occupational stress. The effect of psychological capital on occupational stress was analyzed. RESULTS: Total average score of psychological capital of the study subjects was( 4. 4 ± 0. 7). The average scores of self-efficacy,hope,resilience,optimism dimensions were( 4. 3 ± 0. 9),( 4. 5 ± 0. 8),( 4. 5 ± 0. 8) and( 4. 4 ± 0. 7),respectively. The proportions of active,relaxed,nervous and passive occupational stress accounted for 24. 2%,24. 7%,23. 5% and 27. 6% respectively. The detection rate of JDC mode high occupational stress was 68. 7%( 1 184/1 723). The proportion of active occupational stress of the low-psychologicalcapital group was lower( 28. 3% vs 20. 2%,P < 0. 001),the proportion of passive occupational stress was higher( 23. 4% vs 31. 7%,P < 0. 001),the positive rate of JDC high occupational stress was higher( 63. 3% vs 74. 1%,P <0. 01),compared with the high-psychological-capital group. The multivariate logistic analysis showed that the risk of JDC high occupational stress in the low-psychological-capital group was higher than that in the high-psychological-capital group( P < 0. 01),after eliminating the confounding factors such as length of service,education level and personal monthly income. CONCLUSION: The psychological capital of employees in labor-intensive electronics enterprises was associated with the occupational stress of the JDC model. The occupational stress can be reduced by improving the psychological capital of workers.
