Article Abstract
This study explores the roles of perceived message importance, health anxiety, and health literacy in the relationship between message factors (message label and message valence) and behavioral intentions for rumor verification and sharing. 660 Twitter users responded to unverified information regarding the influenza vaccine. A 3 (label: none vs. news vs. rumor) × 2 (valence: positive vs. negative) online semi-experiment, with a survey to measure health anxiety and health literacy, showed the following results: First, perceived message importance mediated the relationship between message factors and behavioral intentions: only in the condition of the negative message, participants considered a news-labeled message more important than a rumor-labeled or a no-label message. Perceived message importance was associated with intentions to verify and share the message. Second, health anxiety interacted with perceived message importance only when predicting an intention to share the message. Last, healthy literacy interacted with perceived message importance when predicting intentions to both verify and share the message. The results will provide implications for health communication research and practices, especially on managing and controlling rumor dissemination on social media.

While research has explored the use of mHealth in breast cancer prevention, care management, and survivorship, few studies have examined patients' experiences with mobile interventions during the perioperative phase of breast cancer treatment.

We also tested whether lower generalized self-efficacy is associated with higher dementia information avoidance, as the former might be a point of intervention for decreasing defensive information avoidance.

Background: According to the standard definition, a hallucination is 1) a perceptual experience occurring in the absence of a relevant perceptual object, 2) it has the sense of reality of a veridical perception, and 3) it is unwilled and not under voluntary control of the hallucinator.
