Data of Study: Social Network Intervention to Promote Physical Activity among Adolescents

The data sets contain all data and corresponding code books used for analyses in the research described in the SNIPPAA paper by van Woudenberg and Colleagues. The paper tests a social network intervention to promote physical activity in adolescents. In the study, 190 adolescents (46.32% boys; M age = 12.17, age range: 11–14 years) were randomly allocated to either the intervention or control condition. In the intervention condition, the most influential adolescents (based on peer nominations of classmates) in each classroom were trained to promote physical activity among their classmates. Participants received a research smartphone to complete questionnaires and an accelerometer to measure physical activity (steps per day) at baseline, and during the intervention one month later. The date files contain the physcial activity data per day, the sociometric nominations to determine the influence agents in the social network interventions classrooms, overview of the participants, a short evaluation of the influence agents, and the control variables at baseline and during the intervention (Background, Athletic competence, Attitude, Enjoyment, Intentions, Motivation, Self-reported physical activity, Sporting activities, subjective well-being, and a momentary assessment of happiness).本数据集收录了van Woudenberg及其团队发表的SNIPPAA论文中所述研究用于分析的全部数据及对应编码手册。该论文旨在检验一项用于促进青少年体力活动的社交网络干预方案。本研究共纳入190名青少年（男生占比46.32%；平均年龄为12.17岁，年龄范围为11至14岁），并将其随机分配至干预组与对照组。在干预组中，各班内通过同伴提名法选出的最具影响力的青少年将接受培训，以在同班同学中推广体力活动。参与研究的学生被配备专用研究智能手机以完成问卷，同时佩戴加速度计以测量基线期及干预1个月后的每日体力活动步数。本数据集包含各类数据文件：每日体力活动数据、用于确定社交网络干预班级中影响力主体的社会计量提名数据、参与者概况、对影响力主体的简短评估结果，以及基线期与干预期间的控制变量数据，具体包括背景信息、运动能力、态度、愉悦感、行为意向、动机、自我报告体力活动、体育活动、主观幸福感，以及瞬时幸福感评估。
