Social Comparison and State–Trait Dynamics: Viewing Image-Conscious Instagram Accounts Affects College Students’ Mood and Anxiety

The present experiment examined the extent to which appearance-focused accounts on Instagram (a photo-sharing social-media platform) negatively influence people’s moods and anxiety levels. Undergraduates at the University of Florida (N = 81, ages 18–30 years, M = 19.07, SD = 1.56) were randomly assigned to scroll through Instagram accounts with either image-conscious photos (fitness, model, and beauty-blogging accounts) or control photos (food, nature, home-decor accounts). Before (Time 1) and after (Time 2) the experimental manipulation, participants completed state-based mood and anxiety measures, and a one-time measure of trait anxiety. Controlling for Time-1 measures, regression results showed that viewing photos from image-conscious accounts related to decreased positive mood and increased negative mood and anxiety at Time 2. Exploratory analyses showed that people with lower trait anxiety were especially susceptible to feeling more state anxiety after viewing image-conscious photos. These findings advance theory by suggesting that state–trait anxiety dynamics are important to understanding how people react to viewing image-conscious Instagram accounts. Further, a social comparison theory of viewing image-conscious photos online should integrate information about people’s short-term reactions (states, moods) and long-term predispositions (traits, individual differences).
