Effect of CBT Microinterventions on Mechanisms of Behavior Change Among Adults With AUD

Not Applicable

Completed

• Conditions: Alcohol Use Disorder

• Registration Number: NCT03661853
• Lead Sponsor: University of Massachusetts, Worcester

Brief Summary

This proposed R21, Effect of CBT Microinterventions on Mechanisms of Behavior Change among Adults with AUD: Using Eye Tracking to Measure Pre-Post Cognitive Control, uses a translational team science approach to isolate and examine the effect of three different Cognitive Behavioral Therapy (CBT) interventions (functional analysis (FA), cognitive restructuring for alcohol related thoughts (CR), and dealing with cravings (DC)) on specific hypothesized mechanisms (cognitive control, stimulus salience, or craving/arousal, respectively).

Detailed Description

This R21 uses an innovative paradigm pairing a "microintervention" design with eye tracking laboratory tasks used successfully to show deficits of cognitive control over cocaine and nicotine cues, and to objectively measure stimulus salience and craving/arousal in response to alcohol cues. To achieve the study's two specific aims, participants with AUD will be assessed with antisaccade (to measure cognitive control) and attentional bias (to measure stimulus salience and pupil diameter) eye tracking tasks.

Specific Aim 1. To isolate and preliminarily assess the impact of specific CBT microinterventions on potentially malleable hypothesized mechanisms of change in drinking using a novel laboratory paradigm and conducted by a translational science team.

Specific Aim 2. To test specificity of CBT interventions' effect on particular Mechanisms of Behavioral Change, the investigators will test each microintervention's effects on all three purported mechanisms (as stated in "Brief Summary".)

Primary Outcome Measures

Name	Time	Method
Changes in Drinking Behavior	Weekly for up to 3 weeks	Changes in drinking behavior are measured by tracking eye movement patterns using antisaccade + attentional bias eyetracking tasks. Specifically, outcome mediators include changes in cognitive control (# of errors in antisaccade eye-tracking task), changes in stimulus salience (stimulus dwell time measurements), and changes in craving/arousal (pupil diameter changes in response to stimuli presentation.)

Secondary Outcome Measures

Name	Time	Method
Alcohol Use Questionnaire (AUQ)	Weekly for up to 3 weeks	AUQ is an 8-item questionnaire that measures self-reported craving for alcohol. Item scores range from 1-7 and a total score, ranging from 8-56, is calculated by summing all values. Higher scores indicate greater craving.
