摘要
目的探讨大学生手机依赖与自伤行为的关系,以及反刍思维的中介作用和非恢复性睡眠的调节作用。方法2024年12月,采用手机依赖指数量表、反刍思维量表、非恢复性睡眠量表(NRSS)和青少年非自杀性自伤行为评定问卷,对广东省3所高校4560名大学生进行问卷调查,采用SPSS 29.0软件和PROCESS v4.2宏程序进行数据分析,并使用Bootstrap法检验中介效应和调节效应。结果大学生手机依赖的检出率为34.5%(1572/4560),自伤行为的检出率为14.8%(673/4560)。其中,有手机依赖学生的自伤行为检出率(21.2%,333/1572)高于无手机依赖的学生(11.4%,340/2988)(χ^(2)=78.71,P<0.01);有手机依赖的学生和无手机依赖的学生在反刍思维[(44.19±14.24)分,(35.93±12.37)分,t=19.47,P<0.01]和NRSS[(40.63±5.64)分,(45.12±5.84)分,t=-24.97,P<0.01]的评分上差异有统计学意义。对手机依赖学生群体的分析显示,手机依赖程度与反刍思维(r=0.33,P<0.01)和自伤行为(r=0.13,P<0.01)均呈正相关,反刍思维和自伤行为呈正相关(r=0.32,P<0.01),NRSS总分与手机依赖(r=-0.29,P<0.01)、反刍思维(r=-0.37,P<0.01)和自伤行为(r=-0.26,P<0.01)均呈负相关。手机依赖对自伤行为有正向预测作用(β=0.30,P<0.01);反刍思维在手机依赖与自伤行为之间发挥部分中介作用,中介效应量为0.15,占总效应的50.00%(0.15/0.30);非恢复性睡眠调节了手机依赖通过反刍思维影响自伤行为的前半段路径,当非恢复性睡眠较严重时,手机依赖对反刍思维的正向预测作用明显增强(β_(simple)=0.45,P<0.01,95%CI=0.37~0.53);非恢复性睡眠还调节了手机依赖通过反刍思维影响自伤行为的后半段路径,当非恢复性睡眠较严重时,反刍思维对自伤行为的正向预测作用明显增强(β_(simple)=0.29,P<0.01,95%CI=0.20~0.38)。结论大学生手机依赖会加重反刍思维,从而增加自伤行为的风险;对非恢复性睡眠严重的学生,这一影响路径的效应更强。
Objective To explore the relationship between mobile phone addiction and self-injurious behavior among college students,as well as the mediating effect of rumination and the moderating effect of non-restorative sleep.Methods In December 2024,a questionnaire survey was conducted among 4560 students from three universities in Guangdong,using the mobile phone addiction index,ruminative responses scale,non-restorative sleep scale(NRSS)and adolescent non-suicidal self-injury assessment questionnaire.Data analysis was performed using SPSS 29.0 software and the PROCESS v4.2 macro program,with the Bootstrap method used to test mediating and moderating effects.Results The prevalence of mobile phone addiction among college students was 34.5%(1572/4560),and the prevalence of self-injurious behavior was 14.8%(673/4560).The detection rate of self-injurious behavior in college students with mobile phone addiction(21.2%,333/1572)was higher than that in students without mobile phone addiction(11.4%,340/2988)(χ^(2)=78.71,P<0.01).Compared with students without mobile phone addiction,the college students with mobile phone addiction had statistically significant differences in scores of rumination((44.19±14.24),(35.93±12.37),t=19.47,P<0.01))and NRSS((40.63±5.64),(45.12±5.84),t=-24.97,P<0.01)).Analysis of the students with mobile phone addiction showed that the degree of mobile phone addiction was positively correlated with rumination(r=0.33,P<0.01)and self-injurious behavior(r=0.13,P<0.01).Rumination was positively correlated with self-injurious behavior(r=0.32,P<0.01).The total score of NRSS was negatively correlated with mobile phone addiction(r=-0.29,P<0.01),rumination(r=-0.37,P<0.01),and self-injurious behavior(r=-0.26,P<0.01).Mobile phone addiction had a positive predictive effect on self-injurious behavior(β=0.30,P<0.01).Rumination partially mediated the relationship between mobile phone addiction and self-injurious behavior,with a mediating effect size of 0.15,accounting for 50.00%(0.15/0.30)of the total effect.Non-restorative sleep moderated the first stage of the pathway through which mobile phone addiction affected self-injurious behavior via rumination.When non-restorative sleep was more severe,the positive predictive effect of mobile phone addiction on rumination was significantly strengthened(β_(simple)=0.45,P<0.01,95%CI=0.37-0.53).Non-restorative sleep also moderated the second stage of the pathway through which mobile phone addiction affected self-injurious behavior via rumination.When non-restorative sleep was more severe,the positive predictive impact of rumination on self-injurious behavior became significantly stronger(β_(simple)=0.29,P<0.01,95%CI=0.20-0.38).ConclusionMobile phone addiction exacerbates rumination,thereby increasing the risk of self-injurious behavior among college students.This effect is stronger among students with severe non-restorative sleep.
