Identifying Multiple Mechanisms of Change in Alcoholism Treatment
Alcohol DependenceCognitive-behavioral therapy (CBT) is an effective treatment for alcohol dependence, but little is known about how CBT works to achieve these effects. Although several possible mechanisms have been proposed to explain the effects of CBT, it is rare that more than one mechanism is studied. However, it may be the case that similar outcomes (e.g., abstinence) may be reached through multiple paths. Therefore, essential to conducting work on behavioral change mechanisms is distinguishing different courses or paths and moderating influences (Kazdin, 2007). In the present study, we will focus on 2 key mechanisms posited to underlie the effectiveness of CBT specifically, increasing self-efficacy and self-confidence and reducing positive outcome expectancies for alcohol use, and 2 key mechanisms posited to underlie the effectiveness of a wide range of therapeutic interventions, increasing the therapeutic alliance and reducing/regulating negative emotional states. For the present study, participants will be 72 alcohol dependent men and women who agree to participate in a 12-week trial of CBT for alcohol dependence. In addition, comprehensive research assessments will be conducted with patients at baseline, end of treatment, and 3-months posttreatment. Specific Aim 1. To examine the within-treatment week-to-week relationship between ratings of 4 key therapeutic mechanisms and alcohol involvement (operationalized as percent days abstinent {PDA} and drinks per drinking day {DDD}) during treatment. It is hypothesized that self-efficacy, outcome expectancies, therapeutic alliance (as rated by the patient and therapist), and negative affect assessed after any given treatment session will each predict alcohol involvement during the following week. Exploratory analyses also will investigate the relationship of a given week's alcohol involvement on each of the four key variables as assessed the following week. Specific Aim 2. To examine profiles of the four key mechanisms over the course of treatment in relation to alcohol involvement during treatment and during the 3-month follow-up period. These analyses will be descriptive/exploratory. It is expected that profiles will emerge with the key mechanisms that are associated with decreased alcohol involvement (for example, when the alliance is relatively strong throughout treatment or when the alliance grows stronger over the course of treatment, or when positive outcome expectancies grow weaker over the course of treatment, etc.). Similarly, it is hypothesized that profiles will emerge that are associated with little improvement in alcohol involvement (for example, when negative affect is relatively high throughout treatment or when self-efficacy weakens over the course of treatment).
Sweet Preference and Alcohol Craving
Alcohol DependenceAlcohol AbusePurpose: The proposed 2-year investigation will be the first double-blind, placebo-controlled trial examining the hedonic response to sweet taste (HRST) as a phenotypic predictor of naltrexone (NTX) response in alcohol dependence. HRST yields two primary phenotypes-Sweet Likers (SL) and Sweet Dislikers (SDL). Based on preliminary findings, HRST will be examined in conjunction with craving for alcohol to assess whether the two factors together provide a more robust predictor of NTX response. The identification of methods to predict naltrexone response in alcohol dependence is an important goal for alcohol treatment research. Currently naltrexone is not being used nearly as much as it should be, in part because clinicians do not believe it is very effective. The development of tools that would identify which patients are more likely to have a robust response to naltrexone should lead to increased use of the medication. This could help many patients who are not now having the opportunity of trying naltrexone. There are two principal Specific Aims for the study: Specific Aim 1. To test the hypothesis that a combination of SL/SDL status and initial alcohol craving will predict % abstinent days (%ABST) during treatment with naltrexone. Specific Aim 2. To test whether a combination of SL/SDL status and initial alcohol craving predict % heavy drinking days (%HDD) during treatment with naltrexone.
HBPL Study of the Impact of the NK1 Antagonist Aprepitant
Cocaine DependenceAlcohol DependenceThe proposed research will focus on investigating the determinants and consequences of CAD via measurement of physiological, behavioral and subjective effects of physiologic and psychologic stress cues in CAD volunteers in the laboratory, and through examination of the effects of the effects of Aprepitant, an NK1 antagonist, on the above effects. This study will examine the effects of the above stress cues on cocaine and alcohol craving under acute Aprepitant dosing, and under placebo conditions. The study is a within-subjects crossover design using 24 subjects.
Helping Problem Drinkers on the Internet
Alcohol DependenceThe main aim of this study is to compare the impact of a minimal and a full Internet-based self-help intervention for problem drinkers in the general population.
Varenicline Treatment in Alcohol and Nicotine Dependent Patients With Schizophrenia
SchizophreniaSchizoaffective Disorder2 moreThe aim of the proposed pilot study is to find out whether varenicline (ChantixTM) treatment decreases alcohol use and smoking in patients with schizophrenia or schizoaffective disorder. Varenicline may also improve cognition (memory and concentration) and negative symptoms (e.g. poor attention, poverty of speech, apathy, affective flattening, anhedonia) in patients with schizophrenia and comorbid nicotine and alcohol dependence.
Combined Treatment for Alcohol-Dependent Individuals With PTSD
Stress DisordersPost-Traumatic2 moreThis treatment intervention trial is designed for men and women with either alcohol misuse (e.g. hazardous or binge drinking) or alcohol use disorders (alcohol abuse or dependence) and comorbid PTSD. Participants will be randomly assigned to one of two treatments (a cognitive behavioral treatment intervention called "Seeking Safety" + Medication ("Zoloft") or Seeking Safety + placebo) and will be evaluated at baseline, at completion of the treatment (12 sessions over 12 weeks), and again at 6 months and 12 months post-treatment.
Prometa Protocol for Alcohol Dependence
Alcohol DependenceThis is a placebo controlled trial (some people receive active and some people receive inactive medication) to evaluate the effectiveness of a new protocol to treat alcohol dependence. Two main medications (plus ancillary non-placebo controlled medications) and their placebos (inactive drugs) will be utilized to treat both alcohol withdrawal, promote abstinence, and reduce drinking over approximately a six-week treatment period. All participants will meet criteria for Alcohol Dependence and be drinking heavily up until 72 hours prior to receiving the first study drug. They will be injected one drug (flumazenil or placebo) over a two day period and receive the second one (gabapentin or placebo) by mouth for 39 days. The main hypothesis is that this protocol will reduce early alcohol withdrawal symptoms and will reduce relapse to drinking and promote abstinence compared to the placebo (inactive) drug group. Secondary outcomes that will be evaluated include reduction in craving, improvement in sleep, brain activity and mood.
