医学生物质主义价值观和抑郁:生命意义感的中介作用

目的探讨医学生物质主义价值观、抑郁和生命意义感之间的关系。方法采用物质主义倾向量表（MTS）、简版生活目的量表（PIL-SF）、患者健康问卷-9（PHQ-9）对某医科大学1158名医学生进行调查。结果17.33%的医学生有明显抑郁症状；医学生物质主义与生命意义感之间呈显著负相关（r=-0.229，P<0.01），生命意义感与抑郁之间呈显著负相关（r=-0.476，P<0.01），物质主义与抑郁之间呈显著正相关（r=0.246，P<0.01）；生命意义感在物质主义和抑郁之间起部分中介作用，中介效应占总效应比例为41.2%。结论物质主义价值观可直接影响医学生的抑郁水平，也可通过生命意义感的中介作用间接影响其抑郁水平。
