心理病理症状在母亲教养方式与大学生非自杀性自伤行为关联中的中介作用分析

目的 探讨大学生心理病理症状在母亲教养方式与非自杀性自伤（non-suicidal self-injury，NSSI）行为之间的中介作用。方法 采用渥太华自伤量表（ottawa self-injury inventory，OSI）中的自伤判断条目、青少年亚健康多维评定问卷（multidimensional sub-health questionnaire of adolescents，MSQA）、父母教养方式量表（egna minnen av barndoms uppfostran，EMBU）对4 000名大学生进行调查。结果 大学生NSSI的检出率为10.20%。母亲教养方式、心理病理症状与非自杀性自伤之间均呈正相关（均有P<0.05）。Logistic回归分析结果显示，在控制相关因素影响后，不良母亲教养方式（OR=3.56，95%CI:2.71~4.67，P<0.001）、心理病理症状（OR=1.71，95%CI:1.56~1.88，P<0.001）能正向预测NSSI行为发生。Bootstrap法检验结果显示，心理病理症状在母亲教养方式与NSSI行为之间的中介效应占总效应的41.75%。结论 不良的母亲教养方式可能通过心理病理症状影响NSSI行为的发生，帮助该群体正确对待心理病理问题可能有利于其NSSI的预防和控制。

The mediating effect of psychopathological symptoms between mothers' parenting style and non-suicidal self-injury in college students

Objective To explore the mediating effect of psychopathological symptoms between mothers' parenting style and non-suicidal self-injury(NSSI) in college students.Methods Multidimensional sub-health questionnaire of adolescents (MSQA),egna minnen av barndoms uppfostran (EMBU) and some entries from the ottawa self injury scale (OSI) were used to survey 4 000 university students.Results 10.20％ of college students reported to engage in NSSI.Both mothers' parenting style and psychopathological symptoms had significantly positive correlation with non-suicidal selfinjury (all P ＜ 0.05).Logistic regression analysis showed that mothers' parenting style (OR =3.56,95 ％ CI:2.71-4.67,P ＜ 0.001) and psychopathological symptoms (OR =1.71,95％ CI:1.56-1.88,P ＜ 0.001) could positively predict the occurrence of NSSI.The results of Bootstrap test showed that the mediating effect of psychological symptoms between mothers' parenting style and NSSI accounted for 41.75％ of the total effect.Conclusions Poor mothers' parenting styles may affect the occurrence of NSSI through psychological symptoms.Helping the self-injury people deal with the psychopathological problems may be favourable to prevent and control NSSI.
