结构方程模型在医学生心理健康影响因素分析中的应用

目的：利用结构方程模型深入探讨医学生的心理健康的影响因素。方法：用SCL-90、青少年生活事件调查表、简易应对疗式问卷等工具对480名医学大学生进行调查，并对他们的生活事件、对专业的满意度、应对方式及心理症状进行模型似定和验证。结果：学习压力、人际关系、对专业的态度及应对方式与心理健康状况紧密相关。方程拟合效果良好，拟合优度指数、调整拟合优度指数均大于0．90。结论：结构方程模型存使用上比很多传统的统计方法更具有优势，但使用时要与专业知识相结合。

Structural Equation Modeling for Analyzing the Influential Factors of Mental Health in Medical Students

Objective: To deeply investigate the influential factors of mental health in medical students by structural equation modeling.Methods: 480 medical students were tested with SCL-90,adolescent self-rating life events check list and simplified coping style questionnaire,then theoretical model were established and confirmed for the relationships of life events,satisfaction degree with their profession,coping styles and mental health.Results: Study stress,human relations,satisfaction degree towards their profession and coping styles closely correlated with mental health status,and the structural equation modeling fitted the data very well,GFI and AGFI were both larger than 0.90.Conclusion: Use of structural equation modeling has more advantages than the traditional statistical methods,but it should combine with professional knowledge when it is used.
