Network effects on physical activity through interpersonal vs. masspersonal communication with the core and acquaintance networks

Abstract

This study extended the conceptual model of network influence on health behavior by establishing the correspondence between types of social networks (i.e., core and acquaintance networks) and psychosocial processes (i.e., social control and awareness of healthy behaviors) that facilitate increased physical activity among college students. Using an online survey, we identified college students' types of social networks based on their offline and social media activities. Data about psychosocial processes and their physical activity were also collected. Communication with one's core and acquaintance network was related to social control from and awareness of healthy behaviors of both the core and acquaintance network. Nevertheless, only awareness of healthy behaviors from the core network was related to increased physical activity.
