Interventions

  • Contingency Management — BEHAVIORAL
    Contingency Management (CM) is an intervention that uses positive reinforcement (e.g. gift cards) to reinforce a desired behavior (e.g. negative alcohol biomarker tests) on a frequent (e.g. weekly), escalating (e.g. $5/week) schedule (e.g. 26 weeks) in order to increase the occurrence of that behavior (e.g. long term alcohol abstinence or reduction in drinking).
  • Computer Based Training for Cognitive Behavioral Therapy for AUD (CBT4CBT) — BEHAVIORAL
    CBT4CBT is an evidence-based online intervention that teaches CBT principles and skills to help people with alcohol use disorder reduce their drinking. CBT4CBT teaches CBT principles through video, graphics, audio instruction, and interactive exercises. Modules include video-based examples to emphasize learning of behavioral, cognitive, and affective strategies, with an emphasis on learning from examples of individuals using skills in a range of situations. Skills taught include functional analysis, coping with craving and emotions, problem solving, decision making, challenging thoughts, and assertive alcohol refusal. Interactive exercises and homework are used to encourage skills learning and practice.

Study Details

The overall objective of this program of research is to utilize phosphatidylethanol (PEth), a blood-based biomarker that can detect alcohol use for up to 28 days to deliver a feasible telehealth-based 26-week CM intervention. This study will test a telehealth PEth-based CM model in a sample of adults with AUD (n=200), recruited via online platforms by randomizing individuals to six months of 1) an online cognitive behavioral therapy for AUD (CBT4CBT) and telehealth PEth-based CM (CM condition) or 2) CBT4CBT and reinforcers for submitting blood samples (no abstinence required) (control condition). Investigators will assess group differences in PEth-defined abstinence and regular excessive drinking (PEth \>= 200 ng/mL), and alcohol-related harms (e.g., smoking, drug use). This study will address important gaps in CM research by assessing outcomes during a 12-month follow-up, which is much longer than most previous CM studies; using a conceptual model to identify predictors of post-treatment abstinence. Investigators will conduct an economic analysis to place the cost of this model in the context of downstream CM-associated cost-offsets and improvements in personal and public health.

Arms

  • Active Comparator: Control Condition (Non-contingent Incentives + CBT4CBT)
    Participants will receive 8 weeks of Computer Based Training for Cognitive Behavioral Health (CBT4CBT). CBT4BCT is a self paced web-based program that uses videos and lessons to help people learn skills they can use to cut down or stop drinking. Participants will receive a $10 e-gift card for every PEth sample submitted within 48 hours of the visit regardless of the result. Participants will receive gift card incentives when they attend visits and provide blood samples (PEth Samples). Participants will submit PEth samples weekly for the first four weeks of the study, then every two weeks (weeks six, eight), then every four weeks (weeks 12,16, 20, 24), and at week 26. Each time they submit a PEth sample, they will receive gift cards equal to the average CM earnings during the previous month, resulting in total average earnings equivalent to the CM group. This group will receive incentives regardless of the results of their PEth tests.
  • Experimental: CM Condition (Contingency Management + CBT4CBT)
    Participants will receive 8 weeks of CBT4CBT and incentives for timely shipping. In addition, those in the CM Condition will receive at least $20 for each PEth-negative sample. Participants will receive an additional $5 for each week of consecutive negative PEth tests, with a $90 cap. In Initiation Phase, participants will attend virtual visits, provide PEth samples, and be rewarded for a decrease in PEth weekly. Maintenance Phase will begin when a participant's PEth sample is \< 20 ng/mL. In Maintenance Phase, participants will attend visits and submit PEth samples every two weeks for four weeks (i.e., weeks 6 \& 8). They will then attend visits and submit PEth samples every four weeks (weeks 12, 16, 20, 24), and on week 26. If participants submit a positive PEth sample, they will return to Initiation Phase and receive $20 for their next negative sample. Participants will attend visits and submit samples weekly until their PEth level is \< 20 ng/mL and they restart Maintenance Phase.

Primary Outcome Measure
