摘　　要：目的分析电子制造服务业(EMSI)流水线员工抑郁症状与职业紧张、心理资本的关系,探讨心理资本在职业紧张和抑郁症状间的中介效应。方法采用横断面调查方法,以北京市、江苏省和广东省的9家EMSI企业2 269名流水线员工为研究对象。采用《患者健康问卷》《付出-回报失衡问卷》《心理资本问卷》分别进行抑郁症状、职业紧张和心理资本调查;采用层次回归分析探讨职业紧张与心理资本对员工抑郁症状的影响,采用渐进-再抽样策略检验心理资本在职业紧张与抑郁症状间的中介作用。结果研究对象抑郁症状检出率为26. 0%(589/2 269);付出-回报失衡模式职业紧张检出率为26. 6%(603/2 269)。抑郁症状总分与职业紧张的付出和内在投入维度得分均呈正相关[Spearman相关系数(rS)分别为0. 22、0. 34,P <0. 01),与职业紧张的回报维度得分、心理资本总分均呈负相关(rS分别为-0. 37、-0. 39,P <0. 05)。心理资本在职业紧张的付出、回报维度与抑郁症状间起部分中介作用,中介效应百分比分别为14. 8%和23. 7%。结论 EMSI流水线员工心理资本在职业紧张的付出、回报与抑郁症状的关系中发挥部分中介效应;提高其心理资本水平,将有助于缓解抑郁症状。Objective To analyze the association of depressive symptoms,occupational stress and psychological capital( Psy Cay) in employees working in an assembly-line of electronic manufacturing service industry( EMSI),and discuss the mediating effect of Psy Cap in occupational stress and depressive symptoms. Methods A total of 2269 employees who work in an assembly-line from 9 EMSI enterprises in Beijing City,Jiangsu and Guangdong Provinces were selected as study subjects by a cross-sectional survey method. The Patient Health Questionnaire,Effort-Reward Imbalance Scale and Psy Cap Questionnaire were used to investigate their depressive symptoms,occupational stress and Psy Cap. The hierarchical regression analysis was used to explore the effects of occupational stress and Psy Cap on depressive symptoms. The mediating role of Psy Cap was examined using asymptotic and resampling strategies. Results The detection rate of depressive symptoms was 26. 0%( 589/2 269),and the detection rate of effort-reward imbalance model occupational stress was 26. 6%( 603/2 269). The total score of depression symptoms was positively correlated with the scores of the occupational stress effort and over-commitment dimensions [Spearman correlation coefficient( rS) were 0. 22 and 0. 34,respectively,P < 0. 01),and negatively correlated with the scores of the occupational stress reward dimension and the total score of Psy Cay( rSwere-0. 37 and-0. 39,respectively,P < 0. 05). Psy Cap plays a partial mediating role between the dimensions of effort and reward of occupational stress and depressive symptoms,and the mediating effect percentage was14. 8% and 23. 7% respectively. Conclusion The Psy Cap of employees of EMSI assembly-line plays a partial mediating effect in occupational stress effort,reward and depressive symptoms. Increased levels of Psy Cap will help alleviate depressive symptoms.
