Designing Social Media Messages to Promote Action by Suicide Gatekeepers.

Objective: Suicide prevention professionals and programs have focused on reaching not only individuals with suicide ideation, but also family, friends, and other acquaintances, referred to as suicide gatekeepers. Social media provide platforms that allow health communicators to reach a large population. This research focuses on examining and testing the most effective message framing (how the message provides a reward or consequence for the receiver) and message construct (precise focus and wording of a message) for social media posts intended to positively influence suicide gatekeeper intervention behavior on behalf of a friend or peer.

Method: An experiment tested the influence of message construct (between subjects) and message frame (within subjects). The experiment randomized the 1285 participants between the ages of 18 and 34 into the three message construct conditions (significance, preventability, and beneficence).

Results: The results suggest gain-framed messages have a more positive influence than loss-framed messages on all social media message outcome variables (likelihood of social media message engagement, perceived message effectiveness, self-efficacy, response efficacy, empathy, and behavioral expectation), and state empathy mediates the relationship between message frame and these variables. Message construct condition and other mediation results were less substantial, although some evidence suggests that the significance message construct may increase social media message sharing and perceived message effectiveness.

Conclusion: Results show strong evidence of the effectiveness of using gain frames in social media messages aimed at suicide gatekeepers. Other considerations include highlighting the significance of suicide and utilizing empathy appeals to strengthen social media message engagement and behavioral intention.
