Outcome Measures

Primary Outcomes (1)

  • Alcohol Use Assessed by Ethyl Glucuronide (EtG) Detection in Urine

    Proportion of uEtG negative samples during weeks 5-16 of treatment. (EtG \<150 ng/mL = EtG-negative)

    During weeks 5 -16 of treatment

Secondary Outcomes (13)

  • Positive and Negative Syndrome Scale

    At baseline, week 4, 8, 12, 16 through study completion

  • Urinanalysis for Drug Use

    Baseline, during 4-week induction period and 16 weeks of treatment (repeated measure)

  • Addiction Severity Index (ASI)

    Baseline, week 4, 8, 12, 16 through study completion

  • Alcohol and Cigarette Timeline Followback

    Baseline, during 4-week induction period and 16 weeks of treatment (repeated measure)

  • Fagerstrom Test of Nicotine Dependence

    Baseline, week 4, 8, 12, 16 through study completion

  • +8 more secondary outcomes

Study Arms (3)

Usual CM

EXPERIMENTAL

Participants will earn at least 3 prize draws each time they submit an alcohol negative urine samples during weeks 5-20, plus treatment as usual

Behavioral: Usual CM

High-Magnitude CM

EXPERIMENTAL

Participants will earn twice as many prize draws than those in the Usual CM for alcohol abstinence during weeks 5-20, plus treatment as usual.

Behavioral: High-Magnitude CM

Shaping CM

EXPERIMENTAL

Participants will earn prize draws for light drinking during weeks 5-8 instead of alcohol abstinence and will then earn prize draws for abstinence during weeks 9-20, plus treatment as usual.

Behavioral: Shaping CM

Eligibility Criteria

Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

  • A significant risk of medically dangerous alcohol withdrawal (e.g. a history of seizures in the last 12 months, participant or clinician concern that abstinence will induce dangerous alcohol withdrawal).
  • Any medical/psychiatric condition, or severity of that condition, that in the opinion of the PI, would compromise safe study participation.
