Treatment and study plan

LDART

Device

Let's Do Addiction Recovery Together! (LDART) is a web-based intervention grounded in social cognitive theory that is designed to reduce hazardous alcohol use. It has three active ingredients: 1) daily recovery goal setting and tracking, 2) motivational video, audio, and written messages from individuals in recovery, and 3) information on several community-based recovery groups (e.g., mutual-help groups, recovery community centers) that provide free, publicly available meetings and activities. Participants receive a text message reminder each night to go to the website to complete the activities, and a text message reminder each morning of the goal they set for themselves, with the option to change it. It only takes a few minutes to use LDART each day over the 4-week intervention period.

Psychoeducational Control

Behavioral

This is a 20-page psychoeducational booklet created by the National Institute on Alcohol Abuse & Alcoholism (NIAAA) called "Rethinking Drinking". It contains several suggestions, strategies and resources for helping people who want to reduce their alcohol use. Participants will be encouraged to access the booklet for a few minutes each night over the 4-week intervention period.

Primary outcomes

  1. Recruitment rate

    Time frame: From enrollment to the final assessment time point (Day 56)

    The percentage of eligible participants who are enrolled relative to the total number of eligible potential participants who completed the screening.

  2. Accrual rate

    Time frame: From enrollment to the final assessment time point (Day 56)

    The rate of enrollment, defined as number of participants enrolled per month.

  3. Retention rate

    Time frame: From enrollment to the final assessment time point (Day 56)

    The percentage of enrolled participants who complete all study-related procedures (i.e., assessments at 3 monthly time points).

  4. Intervention engagement

    Time frame: From beginning the intervention (Day 1) to the end of the intervention period (Day 28)

    Number of nights that participants in the active condition completed the activities on the LDART website, out of 28 nights.

  5. Intervention acceptability

    Time frame: The second assessment time point (post-intervention, Day 28)

    Rating scores on the end-user version of the Mobile App Rating Scale (uMARS). Total score range 1-5 with higher scores indicating a better quality app.

Secondary outcomes

  1. Change from baseline in number of drinking days

    Time frame: Baseline (Day 0), Post-intervention (Day 28), 1-month post-intervention (Day 56)

    Change in self-reported number of drinking days in the past 28 days, as measured using the Timeline Follow-back.

  2. Change from baseline in number of heavy drinking days

    Time frame: Baseline (Day 0), Post-intervention (Day 28), 1-month post-intervention (Day 56)

    Change in self-reported number of heavy drinking days (defined as 4 or more drinks for women or 5 or more drinks for in one sitting) in the past 28 days, as measured using the Timeline Follow-back.

  3. Change from baseline in number of hours spent engaging with recovery groups

    Time frame: Baseline (Day 0), Post-intervention (Day 28), 1-month post-intervention (Day 56)
