Outcome Measures

Primary Outcomes (2)

  • Startle Potentiation During Stress Reactivity Task

    Startle potentiation is used to study anxiety and fear with No-shock, Predictable-shock, Unpredictable-shock (NPU) task; a common, well-validated laboratory stressor task. In the Predictable condition of the NPU task, shocks are 100 percent predictable and occur at a consistent, known time. In the Unpredictable condition of the NPU task, shocks are fully unpredictable. A higher score on startle potentiation means a higher stress reactivity response for the given condition.

    4 weeks

  • Number of Participants Reporting Any Heavy Drinking Days

    Timeline-followback (TLFB) was administered twice at 4 weeks and 8 weeks. Participants reported the number of drinks per day for each previous 30 day period. Any heavy drinking was scored "yes" if participant reported any days of heavy drinking (\> 4/3 standard drinks for men/women) during the total 8 week assessment period; "no" if no heavy drinking was reported

    8 weeks
