Adolescents are spending considerable time on social media, yet it is unclear whether motivations for social media use drive different forms of social media engagement, and their relationships with body satisfaction and well-being. This study tested a proposed model of the relationships between motivations for social media use, types of social media engagement and body satisfaction and well-being. Responses to an online survey from 1432 Australian adolescents (M = 13.45 years, SD = 1.14, range 11-17; 55.4% boys) were collected. Structural equational modelling indicates excellent model fit. Specifically, motivations for social media use (information sharing, passing time, escapism, social interaction, social capital and appearance feedback) were associated with engagement (intensity, photo-based use, active use, passive use and liking use) and revealed mixed associations with body satisfaction and well-being. The findings support the importance of considering motivations for social media use in future research.
青少年在社交媒体上花费了相当多的时间，但目前尚不清楚社交媒体使用的动机是否会促使他们以不同的形式参与社交媒体，以及这些动机与身体满意度和幸福感之间的关系。本研究检验了一个关于社交媒体使用动机、社交媒体参与类型与身体满意度和幸福感之间关系的假设模型。研究从澳大利亚 1432 名青少年（M=13.45 岁，SD=1.14，范围 11-17；55.4%为男生）中收集了在线调查的回复。结构方程模型表明该模型拟合度非常好。具体而言，社交媒体使用动机（信息分享、消磨时间、逃避现实、社交互动、社交资本和外观反馈）与参与度（强度、基于照片的使用、积极使用、被动使用和喜欢使用）相关，并与身体满意度和幸福感呈混合关联。研究结果支持在未来研究中考虑社交媒体使用动机的重要性。
