人生意义感对戒毒人员复吸风险的影响:自尊和抑郁感的链式中介作用

The effect of meaning in life on drug relapse risk:The mediating roles of self-esteem and depression

目的:探讨人生意义感对戒毒人员复吸风险的影响,以及自尊、抑郁感在两者关系中的中介作用。方法:采用人生意义感量表(MLQ)、自尊量表(SES)、简版流调中心抑郁量表(CES-D-10)和毒品复吸高危量表对255名强制戒毒人员进行调查。结果:①人生意义感与自尊显著正相关(r=0.240,P<0.001),与抑郁感、复吸风险显著负相关(r=-0.300,-0.208;P<0.001);自尊与抑郁感、复吸风险显著负相关(r=-0.387,-0.281;P<0.001);抑郁感与复吸风险显著正相关(r=0.591,P<0.001);②人生意义感不能显著直接影响复吸风险,但可以通过抑郁感的中介作用,以及自尊和抑郁感的链式中介作用间接地影响复吸风险;③抑郁感的中介效应值为-0.130,占总效应的68.783%;自尊-抑郁感的链式中介效应值为-0.046,占总效应的24.339%。结论:人生意义感通过两条路径影响戒毒人员的复吸风险,一条是通过抑郁感的中介作用负向影响复吸风险,另一条是通过自尊和抑郁感的链式中介作用负向影响复吸风险。

Objective:To explore the relationship between drug abstainers’ meaning in life and drug relapse risk,and the possible mediating role of self-esteem and depression between them.Methods:A total of 255 drug abstainers under compulsory rehabilitation were surveyed with the Meaning in Life Questionnaire,Self-esteem Scale,Short Version of Center for Epidemiological Studies Depression Scale(CES-D-10)and Drug Relapse Risk Scale.Results:①Drug abstainers’ meaning in life was positively correlated with self-esteem(r=0.240,P<0.001),and was negatively correlated with depression and drug relapse risk(r=-0.300,-0.208;P<0.001);Self-esteem was negatively correlated with depression and drug relapse risk(r=-0.387,-0.281;P<0.001);Depression was positively correlated with drug relapse risk(r=0.591,P<0.001).②Meaning in life influenced drug relapse indirectly through the mediating role of depression and through the chain mediating role of both self-esteem and depression.③The mediation effect size of depression was-0.130,which accounted for 68.783% of the total effect.The chain mediation effects size of both self-esteem and depression was-0.046,which accounted for 24.339% of the total effect.Conclusion:Meaning in life affects drug relapse risk through two indirect paths:Through the mediating role of depression and the chain mediating role of both self-esteem and depression.
