Addictions Neuroclinical Assessment (ANA)
An observational study of Normal Physiology and Alcohol Use Disorder, run by National Institute on Alcohol Abuse and Alcoholism (NIAAA) at 1 site in United States.
Trial summary
Background: Alcohol use disorder (AUD) is a major public health problem. In the U.S., 16 to 18 million adults have an AUD. Researchers want to test an assessment tool called the ANA. It uses self-report and behavioral measures to assess 3 neuroscience domains of addiction. Read more about this study

- Ages 18 to 99 years
- All sexes
- Healthy volunteers accepted
- Adult, Older adult
Study population: The target population for this study includes adults across the spectrum of alcohol use who have been screened under the NIAAA screening protocol (14-AA-0181). This sample includes non-drinkers, light drinkers, non-treatment-seeking heavy drinkers, and treatment-seeking individuals with alcohol use disorder. Recruitment will be open to all participants from the NIAAA screening protocol.
Who may be able to join
- In order to be eligible to participate in this study, an individual must meet both of the following criteria:
- Participants must be > 18 years of age
- Participants must have enrolled in the NIAAA Screening Protocol (14-AA-0181).
Who cannot join
- There are no formal exclusionary criteria for this study. Based on enrollment criteria for the NIAAA Screening Protocol, individuals less than 18 years of age, or prisoners will not be enrolled in this study.
- Outpatients will be tested for acute intoxication/impairment at the time of consent and study procedures using an alcohol breathalyzer and a clinical evaluation. Individuals with a positive breath alcohol concentration (BrAC), or those who are determined to be acutely intoxicated or impaired by the clinicians will be re-scheduled or withdrawn from the study.
- In addition, individuals who are determined by the clinicians to be uncooperative or unable to provide consent, will not be invited to participate in this study. Individuals who report not being able to use a mouse and keyboard, or who are determined by the clinical research team to be unable to use a mouse and keyboard, will not be invited to participate in this study.

About this study
Official title: Addictions Neuroclinical Assessment
Background:
Alcohol use disorder (AUD) is a major public health problem. In the U.S., 16 to 18 million adults have an AUD. Researchers want to test an assessment tool called the ANA. It uses self-report and behavioral measures to assess 3 neuroscience domains of addiction. They hope to better understand, manage, prevent, and treat AUD.

Objective:
To learn how people s brains function related to their drinking.
Eligibility:
People ages 18 years and older who have enrolled in NIAAA natural history study 14-AA-0181.
Design:
Participants will complete surveys and tasks on a computer. The surveys and tasks assess a range of aspects of thinking and making decisions. The surveys and tasks also assess behaviors and feelings about alcohol and other rewards, and negative emotions. Participants will spend 90 minutes on the computer. Then they will take a break. In total, they will spend 4 blocks of time on the computer. Each block will last 90 minutes. They will take a break in between each block of time. They can take more breaks if needed.
Outpatient participants and healthy volunteers will complete this study in 1 visit. It will last about 6 hours. A second visit may be scheduled if needed. Outpatient participants will take a breath alcohol test. If their test is positive, their visit may be rescheduled or they may be withdrawn from the study.
Inpatient participants will complete this study over several days.
Data collected from participants in this study may be combined and analyzed with their data from NIAAA study 14-AA-0181 and/or NIAAA imaging study 14-AA-0080....

Study Description:
This is a protocol examining a battery of assessments designed to study three neurofunctional domains relevant to alcohol use disorder (AUD), negative emotionality, incentive salience and executive function. The study will examine the relationships among the three ANA domains with the goal of identifying sub-types of AUD based on variation in the ANA domains.
Objectives:
Primary Objectives:
- To examine the relationship between the three ANA domains (i.e. Negative Emotionality, Incentive Salience, Executive Function).
- To identify the different subtypes of AUD based on variation in the ANA domains.
Secondary Objectives: None
Endpoints: Primary Endpoint: Latent factors of each of the ANA domains:
- Negative emotionality
- Incentive Salience
- Executive Function
Secondary Endpoints: None
- Conditions
- Normal Physiology, Alcohol Use Disorder
- Keywords
- Executive Function, Incentive Salience, Negative emotionality, Neurobiology, Alcohol Use Disorder, Natural History

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| non-treatment-seeking individuals | Participants across the spectrum of drinking (from non-drinkers to heavy drinkers) who are not interested in treatment for alcohol use disorder | |
| treatment-seeking individuals with alcohol use disorder | Volunteers with an AUD diagnosis who are seeking treatment for the condition |
What is being measured
The primary outcome is the main question the study is designed to answer.
To examine the relationship between the three ANA domains (i.e. Negative Emotionality, Incentive Salience, Executive Function).
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.
Measured: 1 visit
To identify the different subtypes of AUD based on variation in the ANA domains.
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.
Measured: 1 visit

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?
To examine the relationship between the three ANA domains (i.e. Negative Emotionality, Incentive Salience, Executive Function). (time frame: 1 visit). The study lists 2 primary outcomes in all. 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 NCT04946851, which also lists 3 linked publications.

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 Nov 2026.
