Abstract

Background: Suicide rates have significantly increased in South Korea, yet many individuals lack adequate support. Barriers such as reluctance to seek mental health help and fear of social stigma contribute to this gap. A mobile app focused on suicide risk awareness could provide accessible support, though none are currently available for public use in South Korea. This study conducted a usability test on a newly developed suicide risk awareness app using a mixed methods approach.

Methods: Thirty-eight students from a large university in South Korea participated in the study, with 19 in a high-risk suicide group and 19 in a nonrisk suicide group. After using the app for 2 weeks, all participants completed an online usability survey, and 19 students took part in individual interviews.

Results: Independent samples t-tests showed that participants, regardless of risk group, rated the app positively for ease of use, accessibility, design, perceived learning, and satisfaction. Regression analysis identified perceived learning as the strongest predictor of satisfaction, followed by ease of use. The qualitative analysis highlighted areas for improvement, including providing direct and guided feedback on suicide risk.

Conclusion: The study demonstrated the potential of a mobile app to enhance suicide risk awareness among young adults in South Korea. Moreover, user engagement with the app can be improved by ensuring confidentiality and fostering perceived learning.
