目的采用结构方程模型(SEM)中的交叉滞后模型探讨青少年抑郁情绪和睡眠问题之间的关系。方法采用中国科学院心理研究所全国青少年心理健康数据库的追踪数据,对其中1006名(12-18岁)青少年的三轮追踪数据进行分析。采用流调中心抑郁量表(CES—D)简版和睡眠质量问卷(PSQI)测量青少年的抑郁情绪和睡眠问题,三年追踪研究中,中间平均间隔12个月进行测量。结果T1、T2、T3测量的抑郁情绪得分分别为(5.55-4.70)分、(6.68+5.68)分、(7.00+5.41)分;T2、T3测量的睡眠问题得分分别为(5.01±2.72)分、(5.25±2.76)分。相关分析表明,抑郁情绪与睡眠问题在横向和纵向研究中都显著相关(r=0.20-0.56,P〈0.05);交叉滞后分析发现,青少年的抑郁情绪对下一年的睡眠问题有显著的预测作用(β=0.30,0.11;P〈0.05),同时睡眠问题也对下一年的抑郁情绪也有显著预测作用(β=0.09;P〈0.05);多组比较显示,这种双向预测关系在性别上差异无统计学意义(△χ^2=6.01,P〉0.05)。结论青少年时期的抑郁情绪和睡眠问题之间存在着跨时间且稳定的双向关系,在此发展时期两者能够对彼此产生预测作用。

Objective To explore the bidirectional relationship between adolescent depression and sleep problems using the structural equation model (SEM) approach in a cross-lagged model. Methods The three-round longitudinal data of 1006 adolescents (aged from 12 to 18) were analyzed which were drawn from a longitudinal study named Chinese Adolescent Mental Health Research Program.The adolescents were assessed with the Center for Epidemiological Studies Depression Scale (CES-D) and Pittsburgh Sleep Quality Index (PSQI). The studies were conducted about every 12 months in three years. Results The scores of depression were 5.55±4.70 at first round,6.68±5.68 at the second round and 7.00=t:5.41 at the third round.The scores of sleep problems were 5.01±2.72 at the second round and 5.25±2.76 at the third round. The correlation analyses showed that there were significant cross-sectional and cross-waves correlations between depres- sion and sleep problems ( r= 0.20- 0.56, P〈0.05 ).The cross-lagged model showed that the depression of ado-lescents can predict their sleep problems in the next year(β= 0.30,0.11 ; P〈0.05 ). Meanwhile, sleep problems also had a significant predicted effect on adolescent depression in the next year(β= 0.09; P〈0.05) , the multi-group comparison showed that the bidirectional relationship of prediction had no statistically significant in gender difference( AX2= 6.01, P〉0.05). Conclusion There is a stable bidirectional relationship between adolescent depression and sleep problems across time instead of a one-way relationship. Adolescent depres- sion and sleep problems can predict each other during adolescent development.
