The present cross-sectional study examined the relations of bedtime mobile phone use to cognitive functioning, academic performance, and sleep quality in a sample of undergraduate students. Three hundred eighty-five undergraduate students completed a self-administered questionnaire containing sociodemographic variables, bedtime mobile phone use, the Pittsburgh Sleep Quality Index, and the Cambridge Neuropsychological Test Automated Battery (attention and verbal memory). At bivariate level, increased scores in bedtime mobile phone use were significantly correlated with decreased scores in academic performance and sleep quality. Our multivariate findings show that increased scores in bedtime mobile phone use uniquely predicted decreased scores in academic performance and sleep quality, while controlling for gender, age, and ethnicity. Further untangling the relations of bedtime mobile phone use to academic performance and sleep quality may prove complex. Future studies with longitudinal data are needed to examine the bidirectional effect that bedtime mobile phone use may have on academic performance and sleep quality.
本横断面研究调查了大学生样本中睡前使用手机与认知功能、学业成绩和睡眠质量的关系。385 名大学生完成了一份自我管理的问卷，其中包含社会人口统计学变量、睡前手机使用、匹兹堡睡眠质量指数和剑桥神经心理学测试自动电池（注意力和言语记忆）。在双变量水平上，睡前手机使用评分的增加与学业成绩和睡眠质量的降低呈显著相关。我们的多元分析结果表明，在控制性别、年龄和种族后，睡前手机使用评分的增加可预测学业成绩和睡眠质量的降低。进一步厘清睡前手机使用与学业成绩和睡眠质量的关系可能很复杂。需要进行具有纵向数据的未来研究，以检验睡前手机使用对学业成绩和睡眠质量可能产生的双向影响。
