Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Aim 1 will conduct qualitative, formative work to identify desirable provider- and client-side characteristics of a confidential SMS-based HIV testing referral system.
Aim 2 will adapt an existing mHealth system (mParis) to add CONSORT functionality.
Aim 3 will pilot-test the CONSORT system to collect preliminary data on the system's acceptability, performance, and potential efficacy.
Aim 4 will evaluate the acceptability and efficacy of CONSORT in a randomized controlled trial.
Aim 5 will evaluate the incremental cost-effectiveness of CONSORT vs. other referral options.
If CONSORT is shown to be acceptable, effective, and cost-effective, such mobile-phone supported, chain-referral methods could greatly improve the cost-effectiveness of HIV testing efforts.
