Abstract

Suicide remains a critical public health issue, particularly among young adults, despite declining overall rates in Hong Kong. This study integrates findings from two randomized controlled trials (RCTs) to explore the efficacy of community-based and technology-enhanced interventions in reducing suicide risk and self-harm behaviors among young adults.

The first RCT evaluated a combined approach of a self-help mobile app and volunteer support for a total of 40 post-discharge patients aged 18-45 with self-harm episodes or suicide attempts. Participants were randomly assigned into three groups: mobile app + TAU, mobile app + volunteer support + TAU, and TAU only. Findings revealed that the combination of volunteer care and use of mobile app was effective in improving service compliance and reducing perceived burdensomeness and thwarted belongingness, which led to transient improvements in hopelessness and suicide risk. This underscores the value of technology-enhanced, community-driven care in supporting individuals during the transition from hospital to community settings.

The second RCT examined the impact of a competency-based module (CbM) combined with online social work treatment-as-usual (OSW) for young men aged 18-34 reporting suicide risk. A total of 54 participants was recruited via online forums and assigned to either OSW or OSW+CbM groups in the 2-arm, 4-wave randomized waitlist-controlled trial. Results revealed that the CbM significantly improved self-respect, self-worth, and reduced suicide risk and depression symptoms. Thus, the potential benefits of adopting gender-sensitive interventions in enhancing mental health outcomes have been highlighted.

These studies emphasize the importance of integrating gender-specific, community-based, and technology-enhanced strategies in suicide prevention efforts. The findings advocate for tailored interventions that address psychosocial needs and leverage digital tools to strengthen the continuity of care. This research contributes to advancing intervention designs, informing mental health policies, and inspiring further exploration of innovative approaches to improve the quality of life for young adults – specifically young men – at risk of suicide.
