Title Percentage of Subjects With a World Health Organization (WHO) Drinking Risk Category Decrease of at Least 1-level
Hide Description

Timeline Follow Back data is used to calculate the % of participants that decrease at least 1-level WHO drinking risk category. The WHO has developed a drinking risk categorical scale that can be used in a responder analysis approach to assess clinically relevant decreases in alcohol consumption (Aubin et al-2015). The WHO 1- and 2-level decrease endpoints are the percentage of subjects experiencing at least 1- and 2-level decrease in WHO levels of alcohol consumption, respectively, from the level at baseline (the period including the 28 days before screening) to the level during the last 4 weeks of the maintenance phase (Study Weeks 22-25). The WHO levels are as follows:

Males Females Low Risk 1 to 40g 1 to 20g Medium Risk 41 to 60g 21 to 40g High Risk 61 to 100g 41 to 60g Very High Risk 101+g 61+g

Title Alcohol Craving Score [Alcohol Craving Scale - Short Form (ACQ-SR-R)]
Hide Description

The ACQ-SR-R contains 12-items adapted from the 47-item ACQ-NOW developed by Singleton et al (1994) to assess craving for alcohol among alcohol users in the current context (right now). Each item has a 1 to 7 raw score (from strongly disagree to strongly agree). Items 3, 8, and 11 are reverse keyed. A general craving index is derived by summing all items and dividing by 12. Minimum score is 1 and maximum score is 7. Higher scores are indicative of higher craving.

Mixed effects models as stated in Section 9.4.3 of the SAP will be generated for the total score and for the 4 subscales. Covariates for these models will be identified

Title Alcohol Related Consequences (ImBIBe) Score
Hide Description

ImBIBe is a 15-item questionnaire in which the subject responds on a 5-point scale (0-4) responses to questions on the consequences of alcohol use. This scale was adapted from the Drinker Inventory of Consequences questionnaire based on FDA recommendations on patient reported outcomes (Miller & Tonigen-1995). The potential range is 0-60. A higher score indicates a worse outcome. The questions are added together. A question that is missing is imputed with the average value of all other questions in the questionnaire.The total score is the sum of the individual item scores.

Mixed effects models as stated in Section 9.4.3 will be generated for the total score. Covariates for these models will be identified

The lower the overall score, the better the person sleeps. The tool has an adequate internal reliability, validity and consistency for clinical and community samples of the various populations. Range is (0-21); >6 indicative of "poor" sleep quality.
