Dataset belonging to Siebers et al. (2024) Adolescents' digital nightlife: The comparative effects of day- and nighttime smartphone use on sleep quality

The four datasets 'phone', 'game', 'social', and 'video' are the processed datasets that are used as input files for the Mplus models (but then in .csv instead of .dat format). The dataset 'phone' contains all data related to the main analyses of daytime, pre-bedtime and post-bedtime smartphone use. The datasets 'game', 'social', and 'video' represent the data related to the exploratory analyses for game app, social media app, and video player app use, respectively. The dataset 'timeframes' contains information about respondents' bedtime and wake-up time, which is required to calculate the three timeframes (daytime, pre-bedtime, and post-bedtime).------------------The materials used, including the R and Mplus syntaxes (https://osf.io/tpj98/) and the preregistration of the current study (https://osf.io/kxw2h/) can be found on OSF.

本研究所用的四个数据集分别为"phone"、"game"、"social"与"video"，均为经过预处理的数据集，可作为Mplus模型的输入文件，其格式为.csv而非原始的.dat格式。其中，"phone"数据集涵盖了与日间、睡前及睡后智能手机使用情况的核心分析相关的全部数据。"game"、"social"及"video"数据集则分别对应游戏应用、社交媒体应用与视频播放应用使用情况的探索性分析所需数据。"timeframes"数据集收录了受访者的就寝时间与起床时间信息，该信息是计算日间、睡前及睡后三个时间区间的必要依据。
本研究使用的全部相关材料，包括R语言与Mplus语法文件（https://osf.io/tpj98/）以及本研究的预注册方案（https://osf.io/kxw2h/），均可在开放科学框架（Open Science Framework，简称OSF）平台获取。如需获取更多相关信息，请通过邮箱[e-mail]或[e-mail]联系本文作者。
