Amplification of Positivity for Alcohol Use — AMP-A  

Depression Clinical Trial

Official title: Developing and Evaluating a Positive Valence Treatment for Alcohol Use Disorder With Anxiety or Depression

Status Recruiting

Clinical Trial Summary

The proposed study consists of two phases. During Phase 1, the investigators will recruit a small sample of participants to complete a psychosocial intervention termed Amplification of Positivity (AMP) for individuals experiencing comorbid depression or anxiety disorders and alcohol use disorder (AMP-A). These participants will be asked to provide both qualitative and quantitative input about the AMP-A intervention. Based on their input and clinician input, the AMP-A manual will be modified for use in Phase 2. The goal is to recruit up to 20 participants in order to ensure there will be at least 8 participants who complete all sessions of AMP-A. Phase 2 is a randomized clinical trial (RCT) protocol in which individuals experiencing comorbid depression or anxiety disorders and alcohol use disorder will be randomized to complete AMP-A or an evidence-based cognitive-behavioral therapy (CBT) intervention. Up to 100 participants will be recruited in order to reach a target of N=60. Assessed outcomes will include participant acceptability and completion rates, participant compliance with the intervention, positive and negative affect, substance use- and depression and anxiety-related symptom severity, functional disability, and neural reactivity to reward and alcohol cues during functional magnetic resonance imaging (fMRI).

Clinical Trial Description

Substance use disorder, including alcohol use disorder, is characterized by enhanced neural responsivity to drug (alcohol) cues, but reduced neural responsivity to non-drug reward cues. These effects may be exacerbated by comorbid major depressive disorder (MDD) or symptoms of anhedonia, comorbidities which are particularly high amongst alcohol use disorder. Response rates for current interventions with alcohol use disorder are rather poor, with only 58% experiencing benefits greater than control conditions. There is a need to identify interventions that may target reward responsivity in a way that would promote recovery, reduce affective disturbance, and support better long-term functioning for individuals experiencing alcohol use disorder and comorbid depression and anxiety disorders. Positive affect interventions have recently been developed and tested in other populations (i.e., HIV, anxiety/depression) as a way of enhancing positive valence and reward processing. These interventions have shown significant promise in these populations but have yet to be examined in the context of alcohol use disorder.

The current study would test the feasibility and acceptability of a 12-session protocol focused on amplification of positivity with populations experiencing comorbid alcohol use disorder and depression or anxiety disorders and explore the impact of the intervention on positive affect, negative affect, alcohol use and craving, and neural response patterns during reward and drug cue processing. The proposed project would support the final stages of intervention development. First, an initial pilot study will be conducted to obtain qualitative and quantitative input from N=8 participants with Alcohol Use Disorder (AUD) + Anxiety/Depression (ANX/DEP) who are asked to engage in the amplification of positivity for AUD intervention (AMP-A) and their clinicians to inform modifications to the AMP-A manual. Then, a pilot randomized clinical trial (RCT) will be conducted in which N=60 individuals with Alcohol Use Disorder (AUD) + Anxiety/Depression (ANX/DEP) will be randomized to complete the modified AMP-A intervention or a cognitive behavioral therapy (CBT)intervention. Intervention will consist of 12 sessions that may be done virtually or in-person. Participation in both phases will include completion of interview-based and self-report measures at pre-treatment, weekly during treatment, at post-treatment, and at 3-month follow-up. ;
