Trial summary

Impulsivity, a well-known risk factor predicting negative outcomes, refers broadly to a proclivity towards rapid action with a suboptimal regard for future consequences. Importantly, impulsivity is a multidimensional construct incorporating generalized and behavioral facets. Read more about this study

About this study

Official title: Individual Differences in the Effects of Alcohol (IDEA) Study

Impulsivity, a well-known risk factor predicting negative outcomes, refers broadly to a proclivity towards rapid action with a suboptimal regard for future consequences. Importantly, impulsivity is a multidimensional construct incorporating generalized and behavioral facets. However, underlying mechanisms linking facets of impulsivity to high-risk drinking remain uncertain. Such mechanisms, if uncovered, may be more appropriate intervention targets than impulsivity directly.

Similar to impulsivity, subjective response to alcohol (SR), or individual differences in sensitivity to the pharmacologic effects of alcohol, is an established risk factor for alcohol use disorder. Specifically, experiencing heightened rewarding stimulation and dampened aversive sedation from alcohol are related to high-risk drinking. Theory and recent findings indicate SR and impulsivity may be related, suggesting SR may be a mechanism linking facets of impulsivity to high-risk drinking. However, findings linking impulsivity to SR were all from secondary data analyses and most studies reported on only a single measure of impulsivity. For these reasons, an original data collection using laboratory alcohol administration methods is needed to address which facets of impulsivity are related to SR among young adult drinkers and whether these effects manifest while blood alcohol concentrations are increasing or declining.

This study will utilize a laboratory alcohol administration design to investigate whether distinct facets of impulsivity (i.e., generalized, choice, response) are related to subjective responses (i.e., stimulation and sedation) following alcohol administration.

Read the detailed description

Young adult heavy drinkers, aged 21-30, will enroll in a laboratory alcohol administration study. In a simulated bar laboratory, participants will be administered oral alcohol with three vodka-based drinks. This procedure will allow collection of several measures, notably a widely used, validated measure of self-reported SR and multiple measures capturing facets of impulsive behavior prior to and following alcohol administration. Participants will be recruited through a number of means. Flyers will be posted and handed out in and around the various colleges, universities and technical schools in the Gainesville area as well as in other public areas. The study team will utilize the internet by posting brief solicitation messages on social media, newspaper sites, and classified advertising sites. These same brief messages will also be disseminated to students at the local colleges, universities and technical schools in the area via batch emails and list servs. When permitted, brief recruitment talks will be given verbally during class meetings at these local institutions. Verbal recruitment messages will contain the same material in the appended flyers and other advertisements. Copies of flyers will also be provided at the conclusion of these brief recruitment talks. Potential participants will complete an initial eligibility questionnaire over the phone or online. Participants who appear eligible based on the phone/web screen will be invited to attend an in-person screening appointment. If eligible, participants will be scheduled for two alcohol drinking sessions separated by a minimum of one and a maximum of seven days. After the second drinking session, participants will be scheduled for a follow-up appointment.

What is being measured

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

  1. Biphasic Alcohol Effects Scale

    Biphasic Alcohol Effects Scale is a 14-item, 2-factor model including stimulant and sedative alcohol effects. The minimum value for each of the 2 factors is 0 and the maximum is 70. Higher scores indicate greater stimulation and sedation for each factor, respectively.

    Measured: Up to 6 hours

Secondary outcomes (2)
  1. Subjective Effects of Alcohol Scale

    The Subjective Effects of Alcohol Scale is a 14-item, 4-factor model including low and high arousal positive and negative alcohol effects. The current study assesses specifically high arousal negative (e.g., aggressive) and low arousal positive (e.g., relaxed) alcohol effects.The factor concerning high arousal negative alcohol effects ranges from 0 - 30, with higher scores indicating greater high arousal negative alcohol effects (e.g., aggression). The factor concerning low arousal positive alcohol effects ranges from 0 - 40, with higher scores indicating greater low arousal positive alcohol effects (e.g., relaxed).

    Measured: Up to 6 hours

  2. Alcohol Reward

    The Drug Effects Questionnaire will be used to assess the extent to which participants like the effects of alcohol they are experiencing at the time, rated on a 100-mm line (from "not at all" to "very much") and how much they want more alcohol at the time, also rated on a 100-mm line (from "not at all" to "very much").

    Measured: Up to 6 hours

Why it stopped: The COVID-19 outbreak began, precluding further participant recruitment for this protocol, which could only be conducted in-person. A decision was made that ample data was available to end data collection earlier than anticipated.

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Alcohol in people with Alcohol Use Disorder (AUD) and Subjective Response to Alcohol (SR), run by University of Florida 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 4 inclusion and 3 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: stopped early, as of the sponsor's last update on 6 Dec 2023. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: The COVID-19 outbreak began, precluding further participant recruitment for this protocol, which could only be conducted in-person. A decision was made that ample data was available to end data collection earlier than anticipated.). Results are not available in the source record.

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?

Biphasic Alcohol Effects Scale (time frame: Up to 6 hours). 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 6 Dec 2023.
