农村初中留守儿童自我调节疲劳、抑郁情绪与短视频使用的交叉滞后研究OA

Objective:To explore the causal relationship between self—regulated fatigue,depression and short video use among left—behind children in rural middle schools.Methods:A two—stage longitudinal follow—up investigation was conducted in 259 left—behind children in junior middle school for 16 weeks with self—regulation fatigue scale,depression scale and short video use intensity scale.Results:①There was a significantly positive correlation between self—regulated fatigue and depression among left—behind children in rural middle schools(T1:r=0.69,P＜0.01;T2:r=0.70,P＜0.01);There was a significantly positive correlation between self—regulation fatigue and short vid-eo use among left—behind children in rural middle schools(T1:r=0.33,P＜0.01;T2:r=0.40,P＜0.01).②There were gender differences between self—regulation fatigue and short video use among left—behind children in rural middle schools,and the score of girls was higher than that of boys.③After controlling for pre—test self—regulation fatigue and short video use,pre—test depression significantly positively predicted post—test self—regulation fatigue(β=0.16,P＜0.05);After controlling for pre—test self—regulation of fatigue and depression,pre—test short videos used significantly positive predicted post—test depression(β=0.29,P＜0.001).Conclusion:This study reveals the dy-namic relationship between self—regulated fatigue,depression and short video use of left—behind children in rural middle schools,which has certain guiding value for short video use and psychological development of left—behind children in rural middle schools.
