大学生领悟社会支持和自尊在被动性社交网站使用与抑郁情绪间的链式中介效应

Chain mediating effect of perceived social support and self-esteem between passive social network site use and depression among college students

目的:考察领悟社会支持和自尊在被动性社交网站使用与抑郁情绪间的作用。方法:采用社交网站使用量表、领悟社会支持量表、自尊量表和流调中心抑郁量表对1393名大学生进行问卷调查。采用SPSS 20.0和AMOS 21.0软件,分别进行描述性分析、Pearson相关分析、中介效应检验和结构方程模型建构。结果:被动性社交网站使用、领悟社会支持、自尊和抑郁情绪的总分分别为(13.96±3.47)分、(61.04±12.03)分、(27.28±4.35)分、(31.18±8.74)分。被动性社交网站使用组在领悟社会支持[(60.03±12.25)分]、自尊[(27.03±4.34)分]和抑郁情绪[(31.53±9.06)分]得分上与主动性社交网站使用组[领悟社会支持(63.61±11.03)分、自尊(27.91±4.31)分和抑郁情绪(30.31±7.82)分]差异有统计学意义(t=-5.04,P<0.01;t=-3.39,P=0.001;t=2.35,P<0.01)。控制性别变量后,被动性社交网站使用与抑郁情绪呈正相关(r=0.053,P<0.01),与领悟社会支持和自尊呈负相关(r=-0.157,-0.088,均P<0.01),领悟社会支持与自尊呈正相关(r=0.450,P<0.01)。领悟社会支持和自尊在被动性社交网站使用与抑郁情绪间起部分中介效应。中介效应包括两条路径:一是领悟社会支持的单独中介效应;二是领悟社会支持和自尊的链式中介效应,分别占总效应的27%和25%。结论:被动性社交网站使用可通过领悟社会支持或领悟社会支持和自尊的链式中介间接影响抑郁情绪。

Objective To investigate the role of perceived social support and self-esteem between the passive social network site use and depression among college students.Methods Totally 1393 college students were investigated by social website use scale,perceived social support scale,self-esteem scale and center for epidemiologic studies depression scale.SPSS 20.0 and Amos 21.0 softwares were used for descriptive analysis,Pearson correlation analysis,mediating effect test and structural equation model construction.Results The total scores of passive social network site use,perceived social support,self-esteem and depression were(13.96±3.47),(61.04±12.03),(27.28±4.35)and(31.18±8.74)respectively.The scores of passive social network site use group in perceived social support(60.03±12.25),self-esteem(27.03±4.34)and depression(31.53±9.06)were statistically different with those in the active social network site use group(perceived social support(63.61±11.03),self-esteem(27.91±4.31)and depression(30.31±7.82),t=-5.04,P<0.01,t=-3.39,P=0.001,t=2.35,P=0.019).After controlling gender variables,the use of passive social network sites was positively correlated with depression(r=0.053,P<0.01),while negatively correlated with perceived social support and self-esteem(r=-0.157,-0.088,P<0.01).Perceived social support was positively correlated with self-esteem(r=0.45,P<0.01).Perceived social support and self-esteem played a partial mediating role between passive social network site use and depression.The mediating effect includes two paths:one was the separate mediating effect of social support,and the other was the chain mediating effect of perceived social support and self-esteem,which accounted for 27%and 25%of the total effect respectively.Conclusion The use of passive social networking sites can indirectly affect depression through the perceived social support or the chain mediating of social support and self-esteem.
