Data collection for adolescents and college students was conducted online, while older adults participated through paper-and-pencil tests, facilitated by social workers. The adolescent participants were recruited from two secondary schools in Xinjiang (n = 526) and Gansu (n = 618), with 45.4 % male (n = 522). Baseline data (T1) were collected in September 2020, with follow-up data (T2) gathered in February 2021. The sample from two universities in Gansu comprised the college student group, with males constituting 57.1 % (n= 518) of this cohort. Data collection for this group occurred in April 2021 (T1) and October 2021 (T2). The elderly group, sourced from a community in Jiangsu, had a male representation of 46.4% (n= 212). For these participants, T1 data were collected in September 2020 and T2 data in March 2021.本数据集的研究样本包含1150名青少年（年龄范围13~19岁，平均年龄M=15.95）、907名大学生（年龄范围17~24岁，平均年龄M=20.33）以及457名老年人（年龄范围60~101岁，平均年龄M=85.00）。青少年与大学生的数据采集均通过线上方式完成，而老年参与者则由社会工作者协助完成纸笔测试。青少年参与者招募自新疆的2所中学（n=526）与甘肃的2所中学（n=618），其中男性占比45.4%（n=522）。基线数据（T1）采集于2020年9月，追踪数据（T2）采集于2021年2月。大学生群体的样本取自甘肃的2所高校，该群体男性占比为57.1%（n=518），其数据分别于2021年4月（T1）与2021年10月（T2）完成采集。老年群体样本取自江苏某社区，男性占比为46.4%（n=212），该群体的T1数据采集于2020年9月，T2数据采集于2021年3月。
