Alcohol DependencePhase 4NCT01168960
Identifying Multiple Mechanisms of Change in Alcoholism Treatment
A Phase 4 study testing Cognitive behavioral therapy for alcohol dependence in people with Alcohol Dependence, run by State University of New York at Buffalo at 1 site in United States.
Trial summary
Cognitive-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. Read more about this study

About this study
Cognitive-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).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Cognitive-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).

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Cognitive behavioral therapy for alcohol dependence in people with Alcohol Dependence, run by State University of New York at Buffalo at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Dec 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Timeline Followback for alcohol (time frame: 3-months posttreatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01168960, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Dec 2014.
