目的 基于结构式方程模型评价分析男性产业工人人格特质、生活事件与抑郁症状的相关性,识别抑郁症状高危因素.方法 对首钢迁安公司工人分层随机整群抽样,通过生活事件量表(LES)、大五人格简表(NEO-FFI)以及流调用抑郁自评量表(CES-D)进行评价;应用最大似然法估计结构式方程模型参数,通过修正指数确定最终模型.结果 本研究中抑郁症状(CES-D≥16分)检出率为41.05％,神经质、外向性、宜人性以及负性生活事件对抑郁症状有显著预测作用(r=0.356、-0.304、-0.135、0.227);正性与负性生活事件、神经质与外向性、外向性与责任感、神经质与宜人性共变关系显著,相关系数分别为0.614、-0.469、0.432、-0.402,抑郁症状测量模型中情绪症状、躯体症状及人际关系症状因素载荷分别为0.779、0.678、0.464.结论 男性产业工人抑郁症状发生与神经质、外向性、宜人性以及负性生活事件有关,相关部门应当采取措施对高危工人进行疏导和干预,加强抑郁症的预防.“,”Objective To analyze correlations between personality traits,life events and depressive symptoms based on structural equation model and to identify risky factors of depressive symptoms.Methods Using stratified random cluster sampling method,industrial workers recruited from Shougang Qianan corporation received questionnaire survey consisted of LES,NEO-FFI and CES-D.Maximum likelihood method was applied to calculate parameters of structural equation model,then the final model was confirmed based on modification indices.Results Depressive symptom(CES-D ≥ 16) prevalence was 41.05％ among industrial workers in current study.Neuroticism,extraversion,agreeableness and negative life events were significantly predictive to depressive symptoms (r=0.356,-0.304,-0.135,0.227).Positive and negative life events,neuroticism and extraversion,extraversion and conscientiousness,neuroticism and agreeableness presented high correlation,with coefficients 0.614,-0.469,0.432 and 0.402 respectively.The regression weight of affective symptoms,somatic symptoms and interpersonal relationship in measurement model were 0.779,0.678,0.464.Conclusion The onset of depressive symptoms among industrial workers is remarkably related to neuroticism,extraversion,agreeableness and negative life events.Certain measures are supposed to be conducted for mental nursing and intervention in order to strengthen depression prevention.
