| 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. |
| Measure | Description | Time Frame |
|---|---|---|
| Recruitment rate | The percentage of eligible participants who are enrolled relative to the total number of eligible potential participants who completed the screening. | From enrollment to the final assessment time point (Day 56) |
| Accrual rate | The rate of enrollment, defined as number of participants enrolled per month. | From enrollment to the final assessment time point (Day 56) |
| Retention rate | The percentage of enrolled participants who complete all study-related procedures (i.e., all three assessments). | From enrollment to the final assessment time point (Day 56) |
| Intervention engagement | Number of nights enrolled participants completed the activities on the LDART website, out of 28 nights. | From beginning the intervention (Day 1) to the end of the intervention period (Day 28) |
| Intervention acceptability | 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. | The second assessment time point (post-intervention, Day 28) |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline in stimulant use frequency | Change in self-reported number of days when any stimulants were used in the past 28 days, as measured using the Timeline Follow-back. | Baseline (Day 0), Post-intervention (Day 28), 1-month post-intervention (Day 56) |
