A Framework for Introducing Global Health Innovations to the US.

Background: Across the globe, there are successful health innovations that could help improve public health in US communities at lower cost and with higher effectiveness than standard practice. However, which factors should be considered to heighten the likelihood of successful transfer of global health ideas to the US still warrants more empirical investigation.

Objective: This study aimed to develop a conceptual framework delineating important factors to be considered for successful introduction of global health innovations to US communities, based on diffusion of innovations literature and case studies of global health innovations that have been adopted in US communities.

What Debunking of Misinformation Does and Doesn't.

A web-based experiment ( = 960) examined how debunking of publicly shared news on social media affects viewers' attitudes toward the source who shared the fake news, their agreement with the news position, and perceived credibility of social media as a news platform. Exposure to debunking information did not lower participants' agreement with the news position, but led them to derogate (1) the source who shared the misinformation and (2) social media as a news platform. However, participants who initially favored the source were less likely to attribute the sharing of fake news to the source's dispositions, rather than situational factors, thereby maintaining their positive attitudes toward the source.

Online Self-Tracking Groups to Increase Fruit and Vegetable Intake: A Small-Scale Study on Mechanisms of Group Effect on Behavior Change.

Background: Web-based interventions with a self-tracking component have been found to be effective in promoting adults' fruit and vegetable consumption. However, these interventions primarily focus on individual- rather than group-based self-tracking. The rise of social media technologies enables sharing and comparing self-tracking records in a group context.

Are they talking to me? Cognitive and affective effects of interactivity in politicians' twitter communication.

The present study investigated when and how the level of interactivity in politicians' Twitter communication affects the public's cognitive and affective reactions. In a Web-based experiment (n=264), participants viewed a high profile male politician's Twitter page, wherein he was either actively responding to his followers' questions (high interactivity) or mostly posting messages on his own (low interactivity). Exposure to the high-interactivity Twitter page induced a stronger sense of direct conversation with the candidate (social presence), but only among less affiliative individuals who usually avoid social interaction.
