An interventional study of Customizable personalized normative feedback (CPNF) and Personalized normative feedback (PNF) in Alcohol Use, sponsored by University of Washington. Enrolling by invitation at 1 site in United States. Open to participants aged 18 Years to 24 Years. Per ClinicalTrials.gov, last updated 2026-07-14.
Sponsored by University of Washington · Not applicable, Interventional, and Prevention
The project will develop brief interventions that allow participants to customize which groups they receive feedback for in relation to things such as drinking norms for younger or older students, student athletes, etc. The goal is to provide content that is meaningful and engaging to all users.
The project will develop and pilot test an innovative paradigm for leveraging social norms within brief interventions that entails user customization of which (and how many) normative referent groups they receive feedback for so that the content is meaningful and engaging to all users.

Exclusion Criteria:
N/A
Customizable personalized normative feedback (CPNF) intervention whereby individuals can explore normative feedback for a wider variety of referent groups so that PNF is a truly personalized and engaging experience.
Behavioral: Customizable personalized normative feedback (CPNF)
Standard personalized normative feedback.
Behavioral: Personalized normative feedback (PNF)
Attention-matched control.
Behavioral: Attention-Matched Control (AMC)
The CPNF intervention allows individuals to explore normative feedback for a wider variety of referent groups so that PNF is a truly personalized and engaging experience.
Correcting misperceptions about peers' alcohol use behaviors and contrasting one's own use to the actual norms of their peers.
Participants in the AMC condition will complete all measures at the same time as participants in the CPNF condition but will not receive any information on drinking norms. Instead, participants in the AMC will receive normative feedback on sleep health, video game use, and gambling behaviors, and will similarly be able to choose the normative referent groups they wish to view feedback on for these behaviors. The AMC will thus serve as a non-treatment comparison that controls for assessment reactivity and effects of history and maturation.
Alcohol use - drinks per month
Daily Drinking Questionnaire will assess drinks on average over the past month by recording the number of drinks consumed on each day of a typical week. Response options range from 0 drinks to 25+ drinks. Lower score is a better outcome, higher score is a worse outcome.
Time frame: Screening, Baseline, Follow-ups, an average of 3 months
Alcohol use - Quantity per occasion
Quantity/Frequency/Peak Alcohol Use Index will assess amount of alcohol consumed over the past month with how many days alcohol was consumed, average consumption, and peak consumption. Response options range from 0 to 30 days for frequency, and 1 to 12+ drinks for quantity and peak. Lower score is a better outcome, higher score is a worse outcome.
Time frame: Screening, Baseline, Follow-ups, an average of 3 months
Alcohol use - Heavy episodic drinking
Heavy Episodic Drinking measure will assess how many times over the past month heavy drinking episodes occurred, defined as 4 or more drinks (females) or 5 or more drinks (males) on a single occasion. Response options range from 0 to 7 days. Lower score is a better outcome, higher score is a worse outcome.
Time frame: Screening, Baseline, Follow-ups, an average of 3 months
Alcohol use - Peak drinks & peak BAC
Electronic Blood Alcohol content will be assessed and calculated using peak drinks over x amount of time. A lower BAC is a better outcome, a higher BAC is a worse outcome.
Time frame: Screening, Baseline, Follow-ups, an average of 3 months
Alcohol use - Alcohol Use Disorders Identification Test
The AUDIT is a 10-item self-report screening tool assessing hazardous and harmful alcohol use over the past year. Items are rated on varying 5-point Likert-type scales assessing frequency, quantity, and consequences of alcohol use. Lower score is a better outcome, higher score is a worse outcome.
Time frame: Baseline, Follow-ups, an average of 3 months
Alcohol use - Brief Young Adult Alcohol Consequences Questionnaire
The Brief YAACQ is a 24-item assessment of alcohol-related consequences in young adults. Response options for the items are yes or no. Higher score (i.e. more 'yes' responses) is a worse outcome, lower score (i.e. more 'no' responses) is a better outcome.
Time frame: Baseline, Follow-ups, an average of 3 months
Perceived descriptive norms for each normative referent group
Gathered via Shortened Drinking Norms Rating Form. 7 items assess belief for what's an acceptable number of drinks each day of the week with responses ranging from 0 to 25+ drinks.
Time frame: Baseline, Follow-ups, an average of 3 months
Perceived injunctive drinking norms for typical students at UW
Gathered via the Injunctive Drinking Norms Rating Form. 7 items assess belief for what a typical UW college student drinks on each day of each day of the week with responses ranging from 0 to 25+ drinks.
Time frame: Baseline, Follow-ups, an average of 3 months
Plan to share: Yes — All scientific data (qualitative interview transcriptions, survey response data) will be both preserved and shared. Data will be made publicly available to the research community. This will include but may not be limited to (a) semi-structured interview questions, (b) survey items and corresponding response options (including missingness coding), (c) a codebook for scoring survey items and composite scales, (d) a detailed description of internally computed variables (e.g., time spent viewing intervention content), and (e) documentation of intervention components that participants were exposed to (both treatment and control conditions). Public use and restricted access study data and associated documentation will be made available to the research community free of charge through the NIAAA Data Archive.

Time frame: Data will be shared with the general research community at the time of an associated publication, or the end of the award/support period, whichever comes first.
Access criteria: The data will be made available for sharing with the general research community via the NDA website. Investigators at institutions with a Federal Wide Assurance (FWA) will be able to gain access to NDA data by submitting a data access request in accordance with applicable NDA policies.

Started Jun 2026 (actual). Primary completion is estimated for Nov 2026, 4 months after the start.
Of 328 non-industry interventional studies with no phase under Alcohol Drinking, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 45. This study's planned 4 months is below that.
Counting every sponsor, half of 336 studies reached it within 24 months; a quarter within 10 and three quarters within 45.
