四川省1312名中学生非自杀性自伤行为检出率及其危险因素研究

目的 了解中学生非自杀性自伤行为的检出率及其危险因素.方法 采用青少年危险行为评定量表(RBQ-A)、家庭环境量表简式(FES-F)、调查用抑郁白评量表(CES-D)、青少年生活事件量表(ASLEC)、青少年社会支持量表(SSSA)及自制的一般情况调查量表,于2011年4月以多阶段抽样的方法对四川省彭州市和三台县抽取的1312名中学生进行调查,收回有效问卷1288份;采用多因素logistic回归分析,筛选出中学生非自杀性自伤行为的主要危险因素.结果 1288名中学生中,有22.67％的人在近一年内曾有过非自杀性自伤行为,男女生检出率分别为22.70％、22.64％,两者差异无统计学意义(P＞0.05).有63.36％的人曾采用多种不同的方式进行自我伤害,割伤或烫伤自己者中以男生居多,为26.88％,女生为11.36％.有非自杀性自伤行为者的ASLEC、CES-D的量表分数较无自伤行为者高,而SSSA量表分数则低于无白伤者.logistic回归分析结果显示,家庭矛盾、抑郁情绪、负性生活事件、社会支持少是中学生发生非自杀性白伤行为的主要危险因素.结论 当地中学生非自杀性自伤行为发生率很高,应依据其主要危险因素采取必要的干预措施.

Study on the detection rate and risk factors regarding non-suicidal serf-injurious behavior in middle school students

Objective To understand the prevalence and risk factors of non-suicidal self-injury in middle school students.Methods 1312 middle school students of Pengzhou and Santai were selected to fill in a Risky Behavior Questionnaire for Adoluscents (RBQ-A),Family Environment Scale ( FES ),Center for Epidemiological Survey,Depression Scale (CES-D),Adolescent Self-Rating Life Events Check List (ASLEC),Social Support Scale for Adolescents (SSSA) and self-administered questionnaire.In all the research subjects,1288 were qualified for the study in April 2011 before the risk factors for non-suicidal self-injury were identified by logistic regression.Results In 1288 middle school students,22.67％ had a history of non-suicidal self-injury,with 22.70％ in boys and 22.64％ in girls.63.36％ of students had injured themselves through variouslyways,more seen in boys (26.88％) than in girls (11.36％ ) who cut or burnt themselves.The scores of ASLEC and CES-D in non-suicidal self-injury group appeared higher than that in the control group and the score of SSSA was found higher in the control group.The main risk factors for non-suicidal self-injuries were family conflict,depressive emotion,negative life events and receiving less social support.Conclusion The prevalence of non-suicidal self-injury among middle school students in Pengzhou was high,whicn called for more attention.
