ICT-based mental health services have shown promise in treating Post-Traumatic Stress Disorder (PTSD) among conflict-related victims globally. This replication study aims to validate these findings in a specific context, namely northeastern Kenya. A mixed-methods approach was employed, including quantitative surveys and qualitative interviews with participants and healthcare providers. Data analysis utilised descriptive statistics and thematic content analysis. The study found that while 75% of participants reported improved mental health outcomes after receiving ICT-based services, there were significant variations in service utilization due to socioeconomic disparities. This replication study supports the efficacy of ICT-based mental health interventions for PTSD treatment but highlights the need for targeted strategies to overcome geographical and socio-economic barriers. Future research should focus on developing tailored outreach programmes that address specific community needs, particularly in remote areas with limited access to digital infrastructure.
