Brief Summary:
Randomized pilot study of a device (smartphone app) that poses non-significant risk to participants and is exempt from Investigational Device Exemption regulations [21 Code of Federal Regulations 812.2(c)

Condition or disease Intervention/treatment Phase
Alcohol Use Disorder Behavioral: DynamiCare Rewards Not Applicable

Detailed Description:
To test the feasibility/acceptability and efficacy of a minimum viable product (MVP) of a smartphone app for patients with alcohol use disorder who are in active treatment and recovery to perform self-tracking of their recovery behavior (e.g., abstinence) and focus on their motivation to maintain their desired health behaviors (i.e., abstinence).

Arm Intervention/treatment
Experimental: DynamiCare Rewards
The study will test the feasibility/acceptability and efficacy of DynamiCare Rewards™. DynamiCare Rewards is an iOS/Android app which automates Contingency Management (CM) to help the patient self-monitor and focus attention on his/her behavioral goals (i.e., abstinence) for alcohol or other substance use disorders.
Behavioral: DynamiCare Rewards

Participants assigned to the DynamiCare Rewards group will receive the following:

  1. App on their smartphone
  2. Substance Testing Devices: BACTrack Mobile Pro - submits BAC results directly to smartphone via Bluetooth and Saliva Test Kits.
  3. Next Step debit card to receive financial incentives
  4. Participant will be prompted via the app to conduct breathalyzer/saliva tests, using the devices camera to take "selfie" photo/videos to prevent cheating.
  5. Negative tests result in participant receiving electronic virtual "coins", which can be transferred from reserve account (reserve account inaccessible to participant) to the spendable Next Step debit card.
  6. The amount of coins and funds are available on a progressive variable reward schedule.

No Intervention: Control
Treatment as usual

Primary Outcome Measures :
  1. Percent of participants abstinent from alcohol at each monthly assessment time point (negative urine test and self-report of no use in past 30 days) [ Time Frame: 12-week intervention period ]
    The pilot efficacy study will utilize alcohol abstinence at each assessment time point as the primary outcome. This is defined as a negative ethyl glucuronide urine test (witnessed) at the monthly assessment time points and self-report of no alcohol use in the past 30 days.

Secondary Outcome Measures :
  1. Percent of participants abstinent from all drugs at each monthly assessment time point (negative urine test and self-report of no use in past 30 days) [ Time Frame: 12-week intervention period ]
    Groups will be compared using Generalized Estimating Equation (GEE) analysis on the percent of participants abstinent over time at each time point.

  2. Longest continuous period of abstinence from alcohol and from drugs and alcohol [ Time Frame: 12-week intervention period ]
    Groups will be compared using GEE analysis on the percent of participants abstinent over time at each time point.

  3. Retention in treatment [ Time Frame: 12-week intervention period ]
    Groups will be compared on the number of days retained in treatment according to the site's Electronic Health Record data, and also on the graduation rate from treatment vs. leaving against medical advice.
