Suicide remains a public health concern, and social media platforms have become spaces where suicidal thoughts and behaviors are expressed and observed. This research examines how young adults interpret and respond to suicide-related content on social media. In Study 1 (N = 709), participants viewed mock posts and identified those indicating suicidality; 77% were accurately recognized, particularly those with photos of lethal means. However, 23% of suicidal posts were missed, revealing detection gaps. Study 2 (N = 722) used a within-subjects design to examine how post features (e.g., explicit language, temporal immediacy, and photo inclusion) influence threat appraisal and intervention. Posts were perceived more high risk when they included such factors. Additionally, participants were more likely to report a willingness to engage in indirect responses than direct intervention. Findings emphasize the importance of multimodal cues in online risk detection and the need for interventions that promote effective digital bystander responses.
