Effectiveness of digital psychological interventions for mental health problems in low-income and middle-income countries: a systematic review and meta-analysis
The effectiveness of digital psychological interventions in low-income and middle-income countries remains unclear. We searched databases for articles published in English from inception to March 2020. The primary outcome was post-intervention mental health problems, measured by self-reporting instruments or clinical interviews. Heterogeneity between studies was substantial and there was no evidence of publication bias.
