Research suggests there is an association between high levels of recreational screen time and depression among adolescents; however, mechanisms driving this association remain unknown. The present study examined appearance and weight satisfaction and disordered eating behaviors as mediators in the relationship between recreational screen time and depressive symptoms in adolescents.
Longitudinal data on screen time, depressive symptoms, disordered eating behaviors, and appearance and weight satisfaction from 304 adolescents (194 females, M = 13.40) were analyzed through a moment structure model.
Results revealed appearance dissatisfaction mediated the direct effect of recreational screen time on depressive symptoms (Estimate = 0.48, SE = .18, 95% CI [0.12, 0.84]), and that recreational screen time was significantly related to lower appearance satisfaction (Estimate = -0.06, SE = .02, 95% CI [-0.10, -0.01]), which was significantly predictive of more severe depressive symptoms (Estimate = -1.49, SE = .62, 95% CI [-2.71, -0.28]).
These findings suggest that modulating screen time may be an efficacious strategy to reduce appearance dissatisfaction and depressive symptoms during adolescence.
研究表明，青少年娱乐性屏幕使用时间过长与抑郁症之间存在关联；然而，导致这种关联的机制尚不清楚。本研究将外表和体重满意度以及饮食失调行为作为青少年娱乐性屏幕使用时间与抑郁症状之间关系的中介因素进行了考察。
通过矩结构模型分析了304名青少年（194名女性，平均年龄13.40岁）关于屏幕使用时间、抑郁症状、饮食失调行为以及外表和体重满意度的纵向数据。
结果显示，外表不满介导了娱乐性屏幕使用时间对抑郁症状的直接影响（估计值=0.48，标准误=0.18，95%置信区间[0.12, 0.84]），并且娱乐性屏幕使用时间与较低的外表满意度显著相关（估计值=-0.06，标准误=0.02，95%置信区间[-0.10, -0.01]），外表满意度显著预测更严重的抑郁症状（估计值=-1.49，标准误=0.62，95%置信区间[-2.71, -0.28]）。
这些发现表明，调整屏幕使用时间可能是减少青少年外表不满和抑郁症状的有效策略。
