RESUMEN
BACKGROUND: The World Health Organization's (WHO) Mental Health Gap Action Programme (mhGAP) aims to provide evidence-based guidelines for the management of mental, neurological, and substance use disorders in non-specialized healthcare settings. However, implementing these guidelines remains a challenge due to various factors, including limited training opportunities for primary care providers. This study con the effectiveness of a social media-delivered distance education program on the mhGAP intervention guide, to overcome barriers of technology access and digital literacy, providing a familiar and accessible platform for primary care providers in Jalisco. METHODS: A quasi-experimental study with a pre-test/post-test design was conducted. Primary care providers from Jalisco were invited to participate in a distance education program on the mhGAP intervention guide. The program consisted of online modules, webinars, and discussion forums facilitated by mental health experts. Knowledge assessments were conducted before and after the intervention using a standardized questionnaire. Participant satisfaction and perceived utility were also evaluated through surveys and focus group discussions. RESULTS: A total of 1,096 primary care providers completed the program. The mean knowledge score significantly improved from 58.2% (SD = 12.8%) in the pre-test to 81.4% (SD = 9.6%) in the post-test (p < 0.001), with a large effect size (Cohen's d = 2.04). Subgroup analyses revealed consistent knowledge gains across different demographic and professional characteristics. Participant satisfaction was high, with 92% rating the program's overall quality as "good" or "excellent." Qualitative findings highlighted the benefits of accessibility, flexibility, interactivity, and practical applicability of the distance education approach. CONCLUSIONS: The social media-delivered distance education program on the mhGAP intervention guide effectively improved the knowledge of primary care providers in Jalisco, Mexico. Participants reported high levels of satisfaction and perceived utility. This study demonstrates the potential of distance education strategies to disseminate evidence-based guidelines and enhance mental health service delivery in primary care settings, particularly in resource-limited areas.
