“…These interventions have been successfully applied to areas such as smoking cessation (Valente, Hoffman, Ritt-Olson, Lichtman, & Johnson, 2003), HIV prevention (Kelly, Murphy, & Sikkema, 1997; McKirnan, Tolou-Shams, & Courtenay-Quirk, 2010; NIMH Collaborative HIV/STD Prevention Trial Group, 2010; Safren, et al, 2011), and suicide prevention (Greene, et al, 2011). Because community-based studies often require considerable economic resources, Internet researchers have attempted to use chat rooms and informational websites to reach at-risk participants (Harvey-Berino, et al, 2010; Lipman, Kenny, & Marziali, 2011; Ramadas, Quek, Chan, & Oldenburg, 2011; Rhodes, et al, 2010). Social networking technologies, as a result of their exponential growth and utility in providing social interaction, might be particularly effective platforms for scaling peer-led health education to at-risk populations.…”
