Alcohol PBS and Thinking About the Past

The Protective Behavioral Strategy-20 measure is a 20-item questionnaire assessing the use of three types of Protective Behavioral Strategies: serious harm reduction (8 items), stopping/limiting drinking (7 items), and manner of drinking (5 items). Each item has response options consisting of 1 (Never), 2 (Rarely), 3 (Occasionally), 4 (Sometimes), 5 (Usually), 6 (Always); there is also a Do not wish to respond option. Protective Behavioral Strategy Use scores are average scores for each subscale, with minimum scores of 0 and maximum scores of 6. Higher scores indicate greater use of protective behavioral strategies.

The Young Adult Alcohol Consequences Questionnaire is a 48-item questionnaire assessing problems from alcohol consumption within the last three months. Each item is categorized into one of eight problem domains: social/interpersonal, academic/occupational, risky behavior, impaired control, poor self-care, diminished self-perception, blackout drinking, and physiological dependence. For each item, participants select Yes, No, or Do not wish to respond to indicate whether they have experienced each problem from alcohol consumption (e.g., "I have become very rude, obnoxious or insulting after drinking"). If a participant selects Yes that is indicative of the participant having experienced that specific consequence from alcohol consumption.

To assess an individual's contemplation to change their alcohol drinking behavior, a Contemplation to Change Ladder (Biener & Abrams, 1991) will be used. This ladder displays response options on a ladder graphic, with rungs starting at 0 and ending at 10; each rung increases by one point value as you go up the ladder. Anchors with text descriptions are located at points 0 (No thought of quitting), 2 (Think I need to consider quitting someday), 5 (Think I should quit but not quite ready), 8 (Starting to think about how to change my drinking patterns), and 10 (Taking action to quit e.g., cutting down, enrolling in a program). The higher a participant selects a rung on the ladder, the higher the contemplation to change their alcohol drinking behavior.

A measure that assesses an individual's ability to avoid alcohol if they wanted to as well as binge-drinking or the ability to drink less in the next week

The Perceived Behavioral Control questionnaire measure is made up of six items. Three items assess the individual's ability to avoid alcohol if they wanted to and three items assess binge-drinking or the ability to drink less than 7(females) or 10 (males) units in a single session in the next week. Each item is scored on separate 7-point bipolar adjective scales (e.g., "For me to avoid drinking alcohol is…" very difficult to very easy). The six items will be averaged together to obtain an overall score for Perceived Behavioral Control. Higher scores indicate greater perceived behavioral control to control drinking behavior.

A measure of the amount participants discount delayed rewards

Participants responses about whether they did counterfactuals in the past week and their intentions to use those behaviors in the next week.

Participants are asked to indicate how true each statement in the Personal Assessment of Responsible Drinker Identity Scale is of the participant's experiences overall. Each item of this measure has response options ranging from 1 (not at all true) to 5 (completely true). Higher scores reflect greater agreement with identifying as a responsible drinker.

To assess an individual's contemplation to change their alcohol drinking behavior, a Contemplation to Change Ladder (Biener & Abrams, 1991) will be used. This ladder displays response options on a ladder graphic, with rungs starting at 0 and ending at 10; each rung increases by one point value as you go up the ladder. Anchors with text descriptions are located at points 0 (No thought of quitting), 2 (Think I need to consider quitting someday), 5 (Think I should quit but not quite ready), 8 (Starting to think about how to change my drinking patterns), and 10 (Taking action to quit e.g., cutting down, enrolling in a program). The higher a participant selects a rung on the ladder, the higher the contemplation to change their alcohol drinking behavior.
