This study aimed to evaluate the relationship between group exercise membership, social network characteristics, and general state anxiety in a sample of college students. Participants: 490 undergraduates from a private university in the southern US participated in the study. Methods: An egocentric network analysis was conducted to test whether demographic variables, leisure-time physical activity, group exercise membership, flourishing scores, and network variables were related to anxiety. Results: Regression analyses (R² = .174, F = 7.650, p < .0001) suggest group exercise membership (β = −.105, p = .034) and flourishing scores (β = −.342, p < .0001) were related to lower anxiety scores, while being a racial/ethnic minority (β = .094, p = .036), and having personal networks composed of more people who exercise often (β = .100, p = .025), were related to higher anxiety scores in this sample …
