目的：探索中小学生媒体多任务行为与抑郁的关系，并明确其与自我控制、基本心理需求的关系。方法：通过问卷调查方式，采用随机抽样方法，在成都及重庆城区中小学校收集了有效问卷总共2147份。使用媒体多任务问卷测查媒体多任务使用情况，使用儿童抑郁量表、青少年自我控制双系统量表和基本心理需要满足量表测查个体抑郁水平、冲动控制性、及基本心理需要情况。结果：（1）媒体多任务行为与抑郁得分呈正相关（r=0.341，P<0.01），媒体多任务行为与基本心理需要（r=-0.352，P<0.01）、自我控制呈负相关（r=-0.262，P<0.01）。（2）中介效应结果表明，中小学生媒体多任务行为对抑郁情绪的直接效应显著，效应值为0.045，基本心理需要和自我控制在媒体多任务行为与抑郁之间起到部分中介作用，效应值分别为0.038和0.007，中介效应占比61.290%和11.290%；基本心理需要的中介效应显著大于自我控制。结论：中小学生媒体多任务行为能预测抑郁；控制力强，基本心理需要满足高的个体倾向于进行单一媒体操作，抑郁风险低。
