RESUMO
BACKGROUND: Mental disorders are currently a global public health concern, particularly after the coronavirus disease 2019 (COVID-19) pandemic. Mental health services gradually transitioned to teleservices, employing various methods like texting and videoconferencing. This meta-analysis aimed mainly to quantify the acceptability of tele-mental health services among both beneficiaries and providers. Secondary objectives included quantifying the usability of and satisfaction with these services. METHODS: We conducted a systematic search of the following databases PubMed Central, SAGE, Google Scholar, Scopus, Web of Science, PubMed Medline, and EBSCO according to Preferred Reporting Items of the Systematic Reviews and Meta-Analysis (PRISMA) guidelines until December 2022. RESULTS: Out of 3366 search results, 39 studies fully met the inclusion criteria. The pooled acceptability of tele-mental health services among beneficiaries was [71.0% with a 95% confidence interval (CI) of 63.0 - 78.5%, I2 = 98%]. Using meta-regression, four key factors contributed to this heterogeneity (R2 = 99.75%), namely, year of publication, type of mental disorder, participant category, and the quality of included studies. While acceptability among providers was [66.0% (95%CI, 52.0 - 78.0%), I2 = 95%]. The pooled usability of tele-mental health services among participants was [66.0% (95%CI, 50.0 - 80.0%), I2 = 83%]. Subgroup analysis revealed statistically significant results (p = 0.003), indicating that usability was higher among beneficiaries compared to providers. CONCLUSIONS: The study highlighted a high acceptability of tele-mental health services. These findings suggest a promising outlook for the integration and adoption of tele-mental health services and emphasize the importance of considering user perspectives and addressing provider-specific challenges to enhance overall service delivery and effectiveness.
