About the trial

What the trial wants to find out

The intersection of smoking and HIV/AIDS poses a serious public health threat in Vietnam. Vietnam is dealing with these two challenges with parallel rather than integrated plans. Using a computer-tailored texting intervention, study investigators seek to promote the use of an underused, available, government-funded resource (the Quitline) and Nicotine Replacement Therapy (NRT) that the quitline provides, thus, promoting cessation among PLWH.

The 2 groups in the trial

  • InterventionTreatment being tested

    The M2Q2-HIV intervention includes 3 functions: 1) Extended CHW services, 2) M2Q2 computer-tailored peer messaging, and 3) texting facilitation to quitline use and the quitline intervention. Our goals are to promote the use of an underused, available, government-funded resource for public health (quitline) and NRT that the quitline provides, thus promoting smoking cessation among PLWH.
