Who's most at risk of poor body image? Identifying subgroups of adolescent social media users over the course of a year

Abstract

Types and stability of appearance-related social media use patterns remain under-explored despite established links between social media use and wellbeing. This study aimed to identify subgroups of social media users, and explore whether subgroup membership was stable over time and associated with body image-related outcomes. Adolescents (N = 766; Mage = 12.76, SD = 0.73; 49.40% female) completed four surveys across 1-year, reporting several social media use indices, body dissatisfaction, dietary restraint, and strategies to increase muscle. Latent profile analyses identified two subgroups (moderate and high users), that remained reasonably stable over time. The high subgroup exhibited poorer body image at baseline, though differences seemed to dissipate somewhat over 1-year. Examination of subgroup transition over time showed more rapid increases in poor body image outcomes among social media increasers and more rapid declines for reducers. Prevention programs which aim to reduce high levels of social media use among children, young adolescents, and high-risk individuals (i.e., appearance-focused users) appear warranted.
