Brief summary

In this study, participants will be asked to wear a wrist alcohol biosensor for 30 days and report alcohol use using a ecological momentary assessment (EMA) app. A subset of the sample will be micro-randomized to test two engagement strategies--reciprocity and personalized feedback via the eWrapper app to promote their engagement with the biosensor.

Detailed description

YPLWH (N = 160, 136 after 15% attrition, 18-29 years of age, estimated to include 73% male, 26% female, 1% transgender, 70% racial and ethnic minorities) will be asked to wear a wrist alcohol biosensor (BACtrack Skyn) for 30 days and report their alcohol use using daily ecological momentary assessment (EMA). A subset of the sample will also be assigned to use an app called the eWrapper app that is a game app designed to promote engagement with the Skyn sensor via reciprocity and personalized feedback.

Interventions

BEHAVIORALeWrapper-Engagement strategies to facilitate alcohol biosensor wearing

The eWrapper app includes two engagement strategies (reciprocity and personalized feedback) and implements a micro-randomized trial (MRT) design to test whether the strategies work.

Intervention model description

Participants at the beginning of the trial were not given the eWrapper engagement strategy. Once the eWrapper was fully developed, all participants were then assigned to the eWrapper arm to assess feasibility and acceptability of the eWrapper component.

Design outcomes

Primary

MeasureTime frameDescription
Engagement in Biosensor Wearing30 daysThe percentage of Skyn sensor wearing will be the primary outcome. We will calculate the percentage of time participants wear the sensor during the 30 days, and compare whether this differs between those who have access to the eWrapper vs. those who do not.

Secondary

MeasureTime frameDescription
Feasibility/Acceptability of Biosensor Wearing30 daysSurvey adapted from the System Usability Scale (Brooke, 1986) will be used to assess participant perception of feasibility of wearing the alcohol biosensor. This survey was administered at the conclusion of the 30 day trial. Items in the System Usability Scale were measured on a five-point Likert scale from 1-strongly disagree to 5-strongly agree. The Mean score was calculated to form a total scale score, with a higher number indicating higher overall usability/acceptability. No subscale scores were calculated.
Feasibility/Accessibility of eWrapper30 daysSurvey adapted from the System Usability Scale (Brooke, 1986) will be used to assess participant perception of the eWrapper app. Survey is administered upon conclusion of 30 day trial. Items in the System Usability Scale were measured on a five-point Likert scale from 1-strongly disagree to 5-strongly agree. The Mean score was calculated to form a total scale score, with a higher number indicating higher overall usability/acceptability. No subscale scores were calculated.

Recruitment details

Participants were recruited in Florida both virtually and through clinic partner sites. Recruitment began on February 1, 2023 and concluded on November 30, 2024.

Pre-assignment details

Of the 66 participants who consented and enrolled, only 39 completed the post baseline survey assessment onboarding session for the 30-day Skyn sensor use period, resulting in no group assignment for 27 consented participants.
