摘要:
目的 探讨童年逆境对中学生拖延症的影响,并分析近期压力事件在其中的中介效应及交互作用,为制定青少年拖延症的预防和干预策略提供科学依据。 方法 2023年3月,采用多阶段整群随机抽样方法抽取广州市9所初、高中3 167名学生进行调查,采用自填式问卷调查法收集研究对象人口学特征、童年逆境、拖延症和近期压力、生活事件等情况。运用广义线性混合模型分析童年逆境与中学生拖延症之间的关联,并构建中介模型和相乘交互项及相加交互变量,探讨近期压力事件在其中的中介和交互作用。 结果 有28.8%的中学生报告以前曾遭受过至少1种童年逆境,中学生近期压力事件和拖延症平均得分分别为(18.85±16.69,23.13±9.25)分。调整年龄、性别、学校、家庭居住情况和经济状况、父母文化程度、抑郁症状等因素后,广义线性混合模型分析结果显示,童年逆境及其各维度均与中学生拖延症呈正向关联(β=0.83~3.27,P值均 < 0.05)。中介分析结果显示,近期压力事件在童年逆境和中学生拖延症之间起部分中介作用,中介效应占比为26.7%。交互作用结果显示,童年逆境与中学生近期压力事件的交互作用无统计学意义[交互项OR=0.98,95%CI=0.60~1.36;相对超额危险度(95%CI)=0.87(-0.22~1.96),P值均>0.05]。 结论 童年逆境是中学生拖延症的潜在风险因素,近期压力事件在该关联中发挥部分中介作用。 Abstract:Objective To investigate the influence of childhood adversity on procrastination of middle school students, and to analyze the mediating effect and interaction of recent stressful events, providing a scientific basis for developing prevention and intervention strategies for procrastination behavior in adolescents. Methods In March 2023, a multi-stage cluster random sampling method was used to select 3 167 students from 9 junior and senior high schools in Guangzhou for investigation. Self-administered questionnaires were used to gather information on demographic characteristics, childhood adversity, procrastination and recent stressful life events. Generalized linear mixed models were employed to analyze the association between childhood adversity and procrastination among middle school students. Mediation analysis with multiplicative and additive interaction models were constructed to examine the mediating and interactive effects of recent stressful events. Results Among the middle school students, 28.8% reported experiencing at least one type of childhood adversity. The mean scores for recent stressful events and procrastination were (18.85±16.69) and (23.13±9.25), respectively. After adjusting for age, sex, school, household living conditions and economic status, parental education level, and depressive symptom, generalized linear mixed model analysis revealed that childhood adversity and its subdimensions were positively associated with procrastination among middle school students(β=0.83-3.27, all P < 0.05). Mediation analysis indicated that recent stressful events partially mediated the relationship between childhood adversity and procrastination among middle school students, accounting for 26.7% of the total effect. Interaction analysis showed no statistically significant interaction between childhood adversity and recent stressful events among middle school students[OR(95%CI)=0.98(0.60-1.36), RERI(95%CI)=0.87(-0.22-1.96), both P>0.05]. Conclusion Childhood adversity is a potential risk factor for procrastination among middle school students, and recent negative life events partially mediate this association. -
