Abstract

Project Tech Support2 was a randomized controlled trial that tested three methods of text message delivery for reducing methamphetamine use and HIV risks among MSM. From March 2014 to January 2016, 286 methamphetamine-using MSM were randomized into: (1) interactive text conversations with Peer Health Educators, plus five-times-a-day automated theory-based messages, plus a weekly self-monitoring text-message assessment (TXT-PHE; n = 94); or, (2) the daily automated messages and weekly self-monitoring assessment (TXT-Auto; n = 99); or, (3) weekly self-monitoring assessment only (AO; n = 93). All three conditions demonstrated reductions in methamphetamine use (coef. = - 0.10), sex on methamphetamine (coef. = - 0.09), and condomless anal intercourse (CAI) with casual male partners (coef. = - 0.06). Only participants in TXT-PHE and TEXT-Auto also reduced CAI with main male partners (coef TXT-PHE = - 0.19; coef.TXT-Auto = - 0.16), and only TEXT-Auto participants reduced CAI with anonymous male partners (coef. = - 0.05). Additionally, both theory-based text-messaging interventions achieved sustained reductions in five of the six outcomes through 9 months. Overall, automated delivery outperformed peer-delivered messaging.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
