CPNF Intervention Development and Testing

Not Applicable

• Conditions: Alcohol Use

• Registration Number: NCT07036198
• Lead Sponsor: University of Washington

Brief Summary

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.

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
Alcohol use - Peak drinks & peak BAC	Screening, Baseline, Follow-ups, an average of 3 months	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.
Alcohol use - Heavy episodic drinking	Screening, Baseline, Follow-ups, an average of 3 months	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.
Alcohol use - drinks per month	Screening, Baseline, Follow-ups, an average of 3 months	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.
Alcohol use - Quantity per occasion	Screening, Baseline, Follow-ups, an average of 3 months	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.
Alcohol use - Alcohol Use Disorders Identification Test	Baseline, Follow-ups, an average of 3 months	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.
Alcohol use - Brief Young Adult Alcohol Consequences Questionnaire	Baseline, Follow-ups, an average of 3 months	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.

Secondary Outcome Measures

Name	Time	Method
Perceived descriptive norms for each normative referent group	Baseline, Follow-ups, an average of 3 months	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.
Perceived injunctive drinking norms for typical students at UW	Baseline, Follow-ups, an average of 3 months	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.
