Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Two hundred and ninety-three college students who reported drinking in the past month were randomly assigned to condition in a 2 (self-affirmation: values vs. control writing task) x 2 (implementation intentions: formed vs. not formed) between-subjects factorial design. Participants first completed a self-affirmation or control writing task, then read an article describing the risks of drinking. Next, all participants reported their common drinking behaviors and contexts, and then selected two harm-reduction strategies making either general intentions to use the strategies or making implementation intentions to use the strategies. Alcohol consumption was measured 1 and 2 weeks after the experimental session.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

SA and II

Combined self-affirmation and implementations intention arm

Group Type EXPERIMENTAL

SA and II

Intervention Type BEHAVIORAL

Self affirmation intervention where participants rank 11 values, then write about why their top ranked value is important AND Implementation intentions intervention where participants form two implementation intentions (If/then) statements regarding drinking behavior and write why these are important

SA and No II

Self-affirmation and control intentions condition

Group Type EXPERIMENTAL

SA and No II

Intervention Type BEHAVIORAL

Self affirmation intervention where participants rank 11 values, then write about why their top ranked value is important AND No implementation intentions intervention where participants write why selected health strategies are important (and do nothing else)

No SA and II

Implementation intentions intervention and control writing task

Group Type EXPERIMENTAL

No SA and II

Intervention Type BEHAVIORAL

Control writing intervention where participants rank 11 values, then write about why their 10th ranked value is important to someone else AND Implementation intentions intervention where participants form two implementation intentions (If/then) statements regarding drinking behavior and write why these are important

No SA and No II

Control writing task and control intentions condition

Group Type EXPERIMENTAL

No SA and No II

Intervention Type BEHAVIORAL

Control writing intervention where participants rank 11 values, then write about why their 10th ranked value is important to someone else AND No implementation intentions intervention where participants write why selected health strategies are important (and do nothing else)
