“…Leveraging social media research, we divide OHC use into active (i.e., information sharing) and passive (i.e., information consumption) use i [e.g., 12,52,82] and examine how the way that people use OHCs can increase or decrease the social support they receive. We build on research that finds that group dynamics factors and social relationships can mediate the relationships between personal and situational characteristics and outcomes [e.g., 45,53,62,116] and posit that the relationship between use and received OHC social support is mediated by the nature of the OHCs. To study the nature of the OHCs, we draw on group dynamics research from psychotherapy research that has explained the importance of the three group dynamics of cohesiveness, altruism, and universality in increasing the effectiveness of group therapy [79,123].…”
