Brief Summary

This study aims to create and test an intervention that helps college students re-evaluate their beliefs about food and alcohol disturbance (FAD) and, in turn, reduce how often they engage in it or intend to in the future. The main questions it aims to answer are:

1. 1.Does the intervention help students have less positive beliefs about the effects of FAD and more negative beliefs about its effects?
2. 2.If college students' beliefs about FAD change, does that lead them to engage in it less often or plan to do it less?
3. 3.Will college students who engage in FAD sign up for the study, complete it, and feel that the intervention is helpful and valuable?

Outcome Measures

Primary Outcomes (4)

• Food and Alcohol Disturbance Expectancy Questionnaire

  The Food and Alcohol Disturbance Expectancy Questionnaire is a 30-item self-report questionnaire that assesses positive and negative expectancies for FAD. Participants will be asked to indicate the extent to which they believe or expect each FAD-related outcome to occur if they engaged in FAD, using a five-point scale from 0 (Strongly Disagree) to 5 (Strongly Agree). Scores on each factor will be summed and averaged, with higher scores indicating stronger expectancies.

  This measure will be administered to all participants at baseline, immediately post-intervention, and at the study's one-month follow-up

• Food and Alcohol Disturbance Intentions Questions

  Two questions will be used to assess intentions to engage in FAD for both caloric compensation and alcohol enhancement motives. Items will be rated on a scale from 0 (Very unlikely) to 10 (Very likely), with higher scores indicating greater intentions to engage in FAD.

  This measure will be administered to all participants at baseline, immediately post-intervention, and at the study's one-month follow-up

• College Eating and Drinking Behaviors Scale

  The CEDBS is a 21-item questionnaire that measures the frequency of past-month FAD. Items are rated on a scale from 1 (Never) to 6 (Always), with higher scores indicating more frequent FAD.

  This measure will be administered at baseline and at the one-month follow-up

• Food and Alcohol Disturbance Timeline Followback

  This measure will assess past-month FAD frequency, including FAD motives and compensatory behaviors. The number of days that participants reported engaging in FAD will be summed, with higher scores indicating more frequent FAD.

  This measure will be administered at baseline and at the one-month follow-up

Secondary Outcomes (1)

• Brief Young Adult Alcohol Consequences Questionnaire

  This measure will be administered at baseline and at the one-month follow-up

Study Arms (2)

FAD Expectancy Challenge Condition

EXPERIMENTAL

Participants in the experimental condition will be delivered the FAD expectancy challenge intervention.

Behavioral: Food and alcohol disturbance expectancy challenge

Disordered Eating Psychoeducation

NO INTERVENTION

Participants in the control condition will receive psychoeducation on disordered eating behaviors, with only a brief mention of FAD, and excluding any discussion of expectancies and consequences.

Interventions

Food and alcohol disturbance expectancy challenge BEHAVIORAL

The intervention will focus on strengthening negative FAD expectancies and weakening positive FAD expectancies.
