新型冠状病毒肺炎疫情期间亲子关系与初三学生自杀意念:成长型思维的中介效应与久坐时间的调节效应

Parent-child relationship on suicidal ideation of middle school students during COVID-19 epidemic:A moderated mediation model

目的:探究新型冠状病毒肺炎疫情背景下中学生自杀意念与亲子关系,并着重考察成长型思维及久坐时间在其中所起的作用,揭示中学生自杀意念的发生机制,为减少中学生自杀意念提供科学依据。方法:采用一般情况调查问卷、成长型思维量表(Growth Mindset Scale,GMS)、自杀意念量表(Positive and Negative Suicide Ideation,PANSI)调查湖北省某市17所中学3952名初三学生。结果:(1)男女生的亲子关系(t=-2.24,P<0.05)、成长型思维(t=7.88,P<0.001)、自杀意念(t=-5.49,P<0.001)等方面差异显著;(2)不同来源地学生的久坐时间差异显著(F=102.87,P<0.001);(3)亲子关系不仅直接显著负向预测中学生自杀意念,还通过成长型思维部分中介自杀意念;(4)亲子关系对自杀意念的中介作用受久坐时间的调节,对高久坐时间者的中介作用更强。结论:亲子关系通过成长型思维的中介作用以及久坐时间的调节作用影响中学生自杀意念。减少中学生久坐时间可降低青少年自杀意念。

Objective:To explore the relationship between suicidal ideation and parent-child relationship,growth mindset and sedentary time of middle school students in COVID-19 epidemic,so as to provide a basis for reducing the sedentary time of middle school students and making daily physical exercise plans.Methods:A questionnaire survey was conducted among 3952 junior middle school students from 17 middle schoolsin Hubei province.The process model was used to analyze the direct and indirect effects of growth mindset on suicidal ideation of middle school students.Results:(1)There were significant differences in parent-child relationship(t=-2.24,P<0.05),growth mindset(t=7.88,P<0.001),suicidal ideation(t=-5.49,P<0.001)in different genders.(2)There were significant differences in the sedentary time of students from different places of origin(F=102.87,P<0.001).(3)Parent-child relationship could significantly negatively predict the level of suicidal ideation of middle school students,and influenced suicide ideation through the mediating effect of growth mindset.(4)The mediating effect of parent-child relationship on suicidal ideation was regulated by sedentary time.For individuals with high sedentary time,the mediating effect was stronger.Conclusion:Parent-child relationship can influence the suicidal ideation of middle school students through the mediate effect of growth mindset and the moderate effect of sedentary time.Reducing sedentary time of students,can decrease the suicidal ideation.
