Brief summary

The goal of this study is to evaluate the feasibility, acceptability, and preliminary efficacy of a digital intervention called LDART in adults with stimulant use disorder.

Interventions

DEVICELDART

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.

BEHAVIORALPsychoeducational booklet

This is a 10-page PDF on stimulant use disorder created by the American Society of Addiction Medicine and American Academy of Addiction Psychiatry. It contains information about stimulant intoxication and withdrawal and treatment options. Participants will be encouraged to access this booklet for a few minutes each night over the 4-week intervention period.

Design outcomes

Primary

MeasureTime frameDescription
Recruitment rateFrom 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.
Accrual rateFrom enrollment to the final assessment time point (Day 56)The rate of enrollment, defined as number of participants enrolled per month.
Retention rateFrom enrollment to the final assessment time point (Day 56)The percentage of enrolled participants who complete all study-related procedures (i.e., all three assessments).
Intervention engagementFrom beginning the intervention (Day 1) to the end of the intervention period (Day 28)Number of nights enrolled participants completed the activities on the LDART website, out of 28 nights.
Intervention acceptabilityThe 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

MeasureTime frameDescription
Change from baseline in stimulant use frequencyBaseline (Day 0), Post-intervention (Day 28), 1-month post-intervention (Day 56)Change in self-reported number of days when any stimulants were used in the past 28 days, as measured using the Timeline Follow-back.
Change from baseline in number of hours spent engaging with recovery groupsBaseline (Day 0), Post-intervention (Day 28), 1-month post-intervention (Day 56)Self-reported number of hours spent engaging with recovery groups in the past 28 days, as measured using a modified Timeline Follow-back
