Social Identity, Online Peer Pressure, and Self-Esteem: A Multi-Group SEM Study of Gender Differences among Emerging Adults in Indonesia

This dataset comprises survey responses from 592 Indonesian emerging-adult university students (ages 18–25) across Jakarta, Surabaya, and Bali, including demographics, academic year, primary social media platform, and daily social media usage hours. It contains item-level measures for Social Identity (6 items, 5-point Likert), Online Peer Pressure (6 items, 5-point), and Self-Esteem (7 items, 4-point with two reverse-keyed items), suitable for multi-group SEM by gender examining the relations between social identity, online peer pressure, and self-esteem.本数据集包含来自印度尼西亚雅加达、泗水与巴厘岛三地的592名成年初期大学生（年龄18~25岁）的问卷回复数据，涵盖人口统计学特征、学年、主要社交媒体使用平台及每日社交媒体使用时长等信息。数据集包含社会认同（Social Identity）、网络同伴压力（Online Peer Pressure）与自尊（Self-Esteem）的条目级测量指标：其中社会认同量表含6个条目，采用5级李克特（Likert）量表计分；网络同伴压力量表含6个条目，采用5级计分；自尊量表含7个条目，采用4级计分，且包含2个反向计分条目。该数据集适用于按性别分组开展多组结构方程模型（Structural Equation Modeling，SEM）分析，以探究社会认同、网络同伴压力与自尊三者间的关联关系。
