A study involving the use of text messages for tele-therapy found that the majority of those receiving text therapy vs no therapy at all reported doing better.

From the article abstract: "We searched for randomised trials of interventions to promote antiretroviral adherence within adults in Africa. We searched AMED, CINAHL, Embase, Medline (via PubMed), and ClinicalTrials.gov from inception to Oct 31, 2014, with the terms "HIV", "ART", "adherence", and "Africa". We created a network of the interventions by pooling the published and individual patients' data for comparable treatments and comparing them across the individual interventions with Bayesian network meta-analyses. The primary outcome was adherence defined as the proportion of patients meeting trial defined criteria; the secondary endpoint was viral suppression."
