About

This study aims to examine the feasibility and acceptability of a mobile health intervention to reduce alcohol use and related consequences among young adults. Participants will be randomly assigned to either receive access to the mobile health intervention or receive only generic study surveys. Participants will receive text message surveys sent to their personal cellphone for 4 weeks per their assigned trial arm. All participants will receive a post-survey 30 days after their final weekly survey text.

Full description

This study aims to determine whether a mobile health intervention to reduce alcohol use and related consequences is acceptable and feasible among young adults who engage in high-intensity drinking (HID; 8+/10+ drinks per drinking occasion for females/males, respectively). The investigators aim to recruit 40 adults between 18-25 years of age who report at least one HID episode in the past 30 days.

After providing informed consent, participants will be randomly assigned to receive the mobile health intervention or control surveys only.

Participants will attend one online study visit to enroll in the study and be assigned to their study arm. All subsequent study activities will be completed asynchronously. Participants will then receive text message prompts and/or surveys to their personal cellphone either Wednesday or Thursday through Sunday for four consecutive weeks. Participants will receive a post-test survey 30 days after their final weekly survey.
