Psychosocial and Medication Treatment for Anxiety in Alcoholism

Study Overview
=================
Brief Summary
-----------------
The proposed project is written as a typical clinical practice test and is a fully-controlled trial of a combined anxiety-focused CBT and pharmacotherapy (venlafaxine; CBT-VEN) delivered for patients with comorbid alcohol-use and anxiety disorders. The CBT and pharmacotherapy will be contrasted with relaxation training and placebo medication. One hundred and eighty participants will be recruited and, subsequent to a platform of outpatient treatment for alcoholism, will be randomly assigned to a 12-week treatment condition. All treatment conditions will begin with a 1-week placebo run-in, after which participants will begin a trial of venlafaxine or placebo. The treatments will conclude with a 2-week medication/placebo taper. Follow-up assessments will be conducted at post-treatment and at 3, 6, 9, and 12-months. The long-term objectives of this research are to develop a real-world combination of psychosocial and pharmacological treatments for patients with comorbid alcohol-use and anxiety disorders that compromise prognosis, and to evaluate the effectiveness of combined psychosocial and pharmacological treatments that target anxiety among patients with this comorbidity.

Detailed Description
-----------------
Difficulties in anxiety management are frequent causes of relapse to alcohol use. Empirical data support the role of anxiety in alcohol relapse, and both psychosocial and pharmacological treatments for alcohol problems increasingly address the role of negative affect in alcohol-use disorders. Due to the lack of large, well-controlled treatment outcome trials, the optimal treatment (or combination of treatments) remains unknown. Real world practice in the treatment of alcohol-use disorders frequently begins with brief detoxification and stabilization, and is often followed by some combination of CBT and pharmacotherapy for patients complaining of mood difficulties while attempting early abstinence from alcohol. The purpose of the present study is to evaluate the relative benefits of psychosocial and psychopharmacological therapy for the treatment of co-morbid anxiety and alcohol dependence among patients attempting early abstinence from alcohol. We will address the following four questions: During the course of intervention, is treatment of anxiety disorders with combined treatments of established utility (among non-alcohol-use-disordered patients) superior in managing both return to drinking and anxiety symptoms than either monotherapy, or a fully inactive control treatment? During the follow-up period, will patients who received the combined active treatments fare better in maintaining abstinence relative to the single active treatments, and those in the control condition? What psychosocial variables (such as increases or lapses to elevated anxiety) mediate return to pre-treatment levels of alcohol use? Will baseline indices of alcohol dependence and anxiety disorder severity moderate the relationship between treatment and outcome during both the acute and follow-up phases of the study?

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Clinical Global Impression Scale-I (CGI-I) | Global improvement of alcohol dependence: Rate the total improvement in the participant's alcohol dependence symptoms whether or not, in your judgment, it is due entirely to treatment. Compared to his/her admission to the project, how much has s/he changed? (1-Not assessed, first rating, 2-Very much improved, 3-Much improved, 4-Minimally improved, 5-Unchanged, 6-Minimally worse, 7-Much worse, 8-Very much worse) | Session 1 (Baseline) , Session 8 (8 weeks of treatment), Session 11 (11 weeks of treatment) | 
| Clinical Global Impression Scale-S (CGI-S) | Global severity of alcohol dependence: Considering your total clinical experience with the alcohol dependent population how severe are his/her alcohol dependence symptoms at this time? (1-Normal, no symptoms, 2-Borderline symptoms, 3-Mild symptoms, 4-Moderate symptoms, 5-Marked symptoms, 6-Severe symptoms, 7-Among the most extreme symptoms) | 1 (Baseline) , Session 8 (8 weeks of treatment), Session 11 (11 weeks of treatment) | 
| Craving Desire Scale (CDS) | The Craving Desire Scale (CDS) is a 3-item scale (1. I do want to drink now, 2. I crave a drink right now, 3. I have a desire for a drink right now) used to identify the degree of current alcohol craving, with responses provided on a Likert scale of 1-7: with 1 meaning strongly disagree, and 7 meaning strongly agree to each of the 3 items. Total scores can range from 3 to 21 with higher scores indicating greater craving for alcohol. | 1 (Baseline) , Session 8 (8 weeks of treatment), Session 11 (11 weeks of treatment) | 
| Number of Participants Abstinent | Abstaining from the consumption of intoxicating beverages. | Session 8 (8 weeks of treatment) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Treatment Completion | The number and percent of participants that completed the treatment in each arm of the study. | 12 months | 
| Medication Compliance Rates | The medication compliance rate is the percentage of participants in each study arm who took their medication based on pill counts. | 12 months | 
| DASS Stress Subscale Score | DASS (Depression Anxiety Stress Scales) assesses depression, anxiety and stress responses. Each of the three DASS scales contains 14 items, divided into subscales of 2-5 items with similar content. The stress subscale was used which assesses difficulty relaxing, nervous arousal, and being easily upset/agitated, irritable/over-reactive and impatient. Subjects are asked to use 4-point severity/frequency scales to rate the extent to which they have experienced each state over the past week. Stress scores can range form 0-56 with 0-14=normal, 15-18=mild, 19-25=moderate, 26-33=severe. and 34+=extremely severe stress. | Session 1 (baseline), Session 11 (11 weeks of treatment) | 
| HAM-A Scale | The Hamilton Anxiety Rating Scale (HAM-A) is a psychological questionnaire used by clinicians to rate the severity of a patient's anxiety. The HAM-A probes 14 parameters each item is scored on a 5-point scale, ranging from 0=not present to 4=severe. total scores can range from 0 to 56.where <17 indicates mild anxiety, 18-24 moderate anxiety and 25-30 severe anxiety. Higher scores reflect more anxiety. | Session 1 (baseline), Session 8 (8 weeks of treatment) | 
| HAM-D Scale | HAM-D (Hamilton Rating Scale for Depression) is a multiple item questionnaire used to provide an indication of depression, and as a guide to evaluate recovery. The scoring is based on 17 items. Eight of the items are scored on a 5-point scale, ranging from 0 = not present to 4 = severe. Nine items are scored on a 3 point scale from 0-2 where 0=none or absent and 2= severe. The total scores for the HAM-D can range from 0 to 50. The total scores are interpreted as: 0-7=normal, 8-13=mild, 14-18= moderate, 19-22= severe, and 23+=very severe depression. The higher the score the more severe the participant's depression. | Session 1 (baseline), Session 8 (8 weeks of treatment) |
