摘　　要：目的 探索内在投入在职业应激外源性因子与职业倦怠关联中的中介效应,为明确内在投入的健康效应提供循证依据.方法 于2015年6至7月,对广东省电子制造服务业员工进行分层整群抽样调查,共纳入1994名研究对象.采用知情同意自填问卷进行信息收集,采用付出-回报失衡问卷和职业倦怠通用调查量表分别对电子制造服务业员工的职业应激和职业倦怠进行测量.采用线性分层回归分析和Bootstrap法对内在投入中介效应进行验证.结果 在校正性别、年龄和岗位后,电子制造服务业员工的付出、回报与内在投入标准化回归系数分别为0.28（95％CI：0.24～0.33）和-0.37（95％CI：-0.42～-0.33）,均有统计学意义（P＜0.05）.付出与职业倦怠情感耗竭、人格解体和个体成就感的标准化回归系数分别为0.63 （95％CI：0.54～0.71）、0.18 （95％CI：0.10～0.26）、0.32（95％CI：0.21～0.43）,均有统计学意义（P＜0.05）;回报与职业倦怠情感耗竭、人格解体和个体成就感的标准化回归系数分别为-0.60（95％CI：-0.68～-0.52）、-0.93（95％CI：-1.01～-0.86）、-0.46（95％CI：-0.35～-0.58）,均有统计学意义（P＜0.05）.内在投入中介效应强度为0.093 ～0.218 （P＜0.05）.结论 内在投入可能作为中介变量介导职业应激外源性因子工作付出-回报对职业倦怠的影响效应.Objective To explore the mediating role of over-commitment in the relationship between occupational stressors and job burnout,and to offer more specificevidence-based information in exploring the work related health effects of over-commitment.Methods A total of 1994 samples from electronic manufacturing service industry were collected in Guangdong province based on self-rated questionnaire after written consent from June to July,2015.The Effort-Reward Imbalance questionnaire and Maslach Burnout Invertory-General Survey were used for the measurement of occupational stress and job burnout.And hierarchical regression and Bootstrap test were conducted for data analysis.Results High effort （0.28,0.24-0.33） and low reward （-0.37,-0.42--0.33） were significantly associated with high over-commitment when gender,age and position had been controlled.Standardizedregression coefficient of effort to emotional exhaustion,depersonalization and personal accomplishment were 0.63 （95%CI：0.54-0.71）、0.18 （95%CI：0.10-0.26） 、0.32 （95%CI：0.21-0.43）,P〈0.05;and standardized regression coefficient of reward to emotional exhaustion,depersonalization and personal accomplishment were-0.60 （95%CI：-0.68--0.52） 、-0.93 （95%CI：-1.01--0.86） 、-0.46 （95% CI：-0.35--0.58）,P〈0.05.Bootstrap test indicated the mediation of over-commitment were statistically significant,and mediating effect ranges from 0.093 to 0.218 （P〈0.05）.Conclusion Over-commitment can mediate the relationship between occupational stressors （job effort and reward） and burnout,and the effect varies from different workingconditions.
