About this study

Official title: Alcohol Metabolism and Disease Risk in Asians: Examining the Impact of Personalized Phenotypic/Genotypic Feedback on Early Drinking Trajectories

The goal of this study is to examine the effects of providing personalized information about behavioral, physical, and genetic factors that are associated with elevations in risk for some health problems. The main research question is: can we affect young adult behaviors through communication about these health-related risks? Participants will be asked to complete an in-person baseline session where they provide a DNA sample, complete online surveys, and do a brief interview. They will then receive one of several brief online information sessions and be followed in online surveys approximately every 3 months over the next 2 years.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PHEN feedbackBehavioural

    Feedback on alcohol response (phenotype)

  • PHEN+GENE FeedbackGenetic

    Feedback on both phenotype and genotype (PHEN+GENE)

  • ControlOther

    Feedback that serves as control

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Drinking frequency

    Number of days consumed alcohol

    Measured: up to 2 years post-intervention

  2. Average alcohol quantity

    Average amount of alcohol consumed on drinking days

    Measured: up to 2 years post-intervention

Secondary outcomes (4)
  1. Amount of alcohol consumed

    Total number of drinks consumed

    Measured: up to 2 years post-intervention

  2. Maximum daily alcohol

    Highest number of drinks consumed on one day

    Measured: up to 2 years post-intervention

  3. Use of flush cures

    Proportion of drinking days used flush cures

    Measured: up to 2 years post-intervention

  4. Use of drinking behavioral strategies

    Proportion of drinking days used behavioral strategies

    Measured: up to 2 years post-intervention

Questions about this trial

What is this clinical trial studying?

A study testing PHEN feedback and PHEN+GENE Feedback in people with Healthy and Alcohol Consumption, run by University of Southern California 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: opening soon, as of the sponsor's last update on 18 Jun 2026. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Susan Luczak, PhD (2137402203, luczak@usc.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Drinking frequency (time frame: up to 2 years post-intervention). 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?
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 18 Jun 2026.
