TRIS: Contingency Management App for Alcohol Use Disorder
Sponsor: University of Sao Paulo General Hospital
Summary
Alcohol Use Disorder (AUD) is a major public health concern associated with substantial morbidity, mortality, and impaired social and occupational functioning. Contingency Management (CM) is an evidence-based behavioral intervention that provides incentives contingent on abstinence and has demonstrated effectiveness in the treatment of substance use disorders. This study will evaluate the efficacy of Tratamento Remoto com Incentivos à Sobriedade (TRIS), a Brazilian mobile health application that integrates a smartphone app with a Bluetooth-enabled breathalyzer (BACtrack) to deliver remote CM for AUD. Participants will be randomized to receive either standard outpatient treatment plus TRIS-based CM or standard outpatient treatment with remote alcohol monitoring only. The primary objective is to determine whether TRIS-based CM increases biochemically verified alcohol abstinence compared with standard outpatient treatment alone.

Interventions
Remote Contingency Management (CM)
Remote contingency management delivered through the TRIS mobile application. Participants submit three daily breath alcohol concentration (BrAC) samples using a Bluetooth-enabled BACtrack breathalyzer. Monetary incentives ranging from R$5.00 to R$15.00 per day are provided contingent on verified alcohol abstinence.
Treatment as Usual (TAU)
Standard outpatient treatment for Alcohol Use Disorder provided at the participating outpatient clinics. Participants also use the TRIS mobile application and a Bluetooth-enabled BACtrack breathalyzer for remote alcohol monitoring but do not receive contingency management incentives.
