SECONDARY outcome

Timeframe: 8 week outcome period

Population: Participants who were randomized and received treatment.

Alcohol craving assessed using the weekly Obsessive Compulsive Drinking Scale (OCDS). This 14-item scale is a quick and reliable self-rating instrument that provides a total and two subscale scores that measure some cognitive aspects of alcohol "craving". Obsessive subscale is the summation of items 1-6 with score range 0-24. Compulsive subscale is the summation of items 7-14 with score range 0-32. Total score range 0-40. Higher scores indicate more obsessions and compulsions with alcohol.

SECONDARY outcome

Timeframe: assessed weekly, score at week 8 reported

Population: Participants who were randomized and received treatment.

The Hospital Anxiety and Depression Scale (HADS) will be used; it has 2 subscales (one for depression and one for anxiety) each with 7 items. It is a brief measure of generalized symptoms of anxiety and fear. Respondents indicate how they currently feel and responses are rated on a 4-point Likert scale with total score range from 0 to 21. Total scores are the sum of all items. Total scores are reported. Higher scores indicate higher levels of depression or anxiety.
