Understanding Alcohol Use Disorder with the ANA Assessment

This study is using a set of assessments called the Addictions Neuroclinical Assessment (ANA) to better understand alcohol use disorder (AUD). Researchers want to see how different brain functions, like emotions, motivation, and decision-making, are related to drinking. They hope to find different types of AUD based on how people score on these assessments. This could help improve how AUD is managed, prevented, and treated. You can join if you are 18 or older and are already part of another study called NIAAA Screening Protocol (14-AA-0181). The study is currently unclear on its recruitment status.

Study design
This is an observational study planning to enroll 1400 participants. It is not testing a new treatment, but rather observing and collecting information.
What's involved
You will complete surveys and tasks on a computer during one visit. These will assess your thinking, decision-making, feelings about alcohol, and emotions.
Compensation
Not stated in the trial record.
Follow-up
The primary goals of the study are measured at one visit, so there is no specified follow-up period.

What this trial measures

  • To examine the relationship between the three ANA domains (i.e. Negative Emotionality, Incentive Salience, Executive Function).1 visit

    Once the latent factors associated with each of the three ANA domains are identified, structural relationships between the latent factors can be modeled and described.

  • To identify the different subtypes of AUD based on variation in the ANA domains.1 visit

    Additionally, once the latent factors are identified, they can be used to categorize individuals into latent groups (AUD subtypes) based on the variation of their scores on each of the domains.
