简要总结
The goal of this study is to determine whether intravenous infusion of allopregnanolone (ALLO) attenuates stress-induced craving and stress-induced anxiety in a clinical laboratory setting. The secondary objective of this project is to characterize the behavioral effects of ALLO in heavy drinkers.
详细描述
This is a double-blind, placebo-controlled study that will randomize heavy "at risk" drinkers to 2 groups: targeted dose of 100 nM of ALLO or placebo. Participants will receive a continuous infusion of ALLO (or placebo) for approximately 175 min. Sixty minutes after the start of the infusion, when ALLO levels are relatively stable, the stress induction paradigm will be introduced. Participants will be presented with a stress cue and a neutral cue in random order. Stress and neutral cues will consist of personalized 5-minute scripts created prior to testing. Measures of stress-induced craving and stress-induced anxiety will be presented before the cue (pre), immediately following the cue (post) and 10 minutes after (recovery). An alcohol infusion (40mg%) begins at approximately 120 minutes into ALLO Infusion. Once the alcohol infusion has reached the targeted dose of 40mg% the infusion is clamped for approximately 20 minutes. The study outcomes will include measures of stress-induced craving and stress-induced anxiety as well as measures of subjective mood effects, cognitive performance, and motor coordination.

Alcohol Urge Questionnaire (AUQ) Pre-script
时间窗: Pre-Script 40 minutes before trauma/neutral script is presented
The Alcohol Urge Questionnaire (AUQ) is an 8-question, self-administered measure of drinking urges. Questions are in the form of a 7-point scale with participants endorsing the extent to which they agree or disagree with statements relating to desire to drink (4 items), expectation of a desired outcome from drinking (2 items), and inability to avoid drinking if alcohol was available (2 items). Total scores range from 8 (strongly disagree) to 56 (strongly agree).

Total scores range from 8 (strongly disagree) to 56 (strongly agree).
The State-Trait Anxiety Inventory (STAI-6) I Feel Upset - Pre-Script
时间窗: Pre-Script 40 minutes before trauma/neutral script is presented
The State Trait Anxiety Inventory (STAI-6) is a 6-item self-rated instrument used to assess anxiety state. The STAI-6 questions included: 1. "I feel calm"; 2. "I am tense"; 3. "I feel upset"; 4. "I am relaxed"; 5. "I feel content"; 6. "I am worried". Each of these questions were rated as: a) "not at all"; b) "somewhat"; c) "moderately"; d) "very much". For questions 2, 3, and 6, the scoring was a = 1, b = 2, c = 3, and d = 4. For the other 3 questions, the scoring was a = 4, b = 3, c = 2, and d = 1. This outcome is for 3. "I feel upset" (scored individually): the scoring for "I feel upset is: a = 1, b = 2, c = 3, and d = 4 (1 not at all upset to 4 very much upset)
