Integration of Village Public Broadcasting and the Role of Village Health Volunteers (VHVs) in Suicide Prevention in Nong Ki District, Buriram Province.

Abstract

     This study aimed to evaluate the effectiveness of integrating village public broadcasting and the role of Village Health Volunteers (VHVs) in suicide prevention and surveillance, as well as the use of QR Code-based mental health screening to enhance public awareness, knowledge, attitudes, and behaviors. This survey research conducted in Thung Kratat Phatthana Subdistrict, Nong Ki District, Buriram Province, Thailand. The sample includes 357 community members and 30 VHVs. Data collection methods consist of pre- and post-intervention surveys (Pre-test and Post-test), in-depth interviews, and focus group discussions. Quantitative data were analyzed using t-tests and ANOVA, while qualitative data were analyzed using Thematic Analysis.

     The results showed a significant improvement in the perceived role of VHVs, with the mean score increasing from 3.4 to 4.47 (p < 0.001). Public knowledge about suicide prevention increased across all age groups, with the most significant improvement among individuals aged 50 years and above (p < 0.001). Public attitudes toward mental health improved, especially among those aged over 50 years (mean score increased from 3.58 to 4.35). Mental health surveillance behaviors also improved, particularly among individuals under 30 years (2.47 to 4.11). Community members who regularly listened to public broadcasts demonstrated higher awareness of VHVs' roles and more positive attitudes compared to those who listened occasionally.The QR Code-based mental health screening system facilitated public mental health self-assessment, revealing that 5.71% of respondents showed signs of depression, and 1.90% were at risk of self-harm.
