About this study
Official title: Digital Mindfulness-Based Treatment for Individuals in Early Recovery From Substance Use Disorders
The goal of this clinical trial is to evaluate the feasibility and acceptability of a digital mindfulness-based treatment for individuals in early recovery from substance use disorders. Participants are randomized to treatment-as-usual (TAU) or TAU plus the digital mindfulness-based treatment. The digital treatment will be completed over an 8-week period.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Treatment-as-Usual (TAU)Behavioural
TAU consists of weekly outpatient-based group therapy for substance use disorder
Digital Mindfulness TreatmentBehavioural
The digital mindfulness-based treatment is a multimedia app-based program teaching mindfulness skills to facilitate recovery from substance use disorder
| Study group | Role | What they receive |
|---|---|---|
| Treatment-as-Usual (TAU) | Active comparator | TAU consists of weekly outpatient-based group therapy Receives: Behavioral: Treatment-as-Usual (TAU) |
| TAU Plus Digital Mindfulness-Based Treatment | Experimental | TAU consists of weekly outpatient-based group therapy. The digital mindfulness-based treatment is multimedia app-based program teaching mindfulness skills. Receives: Behavioral: Treatment-as-Usual (TAU); Behavioral: Digital Mindfulness Treatment |
What is being measured
The primary outcome is the main question the study is designed to answer.
Adherence to the Digital Treatment
Number of randomized participants completing 50% or more of the digital treatment modules. This outcome was only assessed in the digital mindfulness arm.
Measured: 8-week treatment period that begins on the day participants are randomized
Completion Rates for the Post-treatment Assessment Visit
Percentage of participants that completed post-treatment assessment visit of all randomized participants
Measured: Approximately 9 weeks after randomization
Completion Rates for the 2-month Follow-up Assessment Visit
Percentage of participants that completed 2-month post-treatment assessment visit of all randomized participants
Measured: 2-month post-treatment follow-up (approximately 16 weeks post-randomization)
Completion Rates for Ecological Momentary Assessment at Baseline
Percentage of participants that completed 50% or more of EMA surveys at baseline of all randomized participants
Measured: 2-week period at baseline prior to randomization
Completion Rates for Ecological Momentary Assessment Post-treatment
Percentage of participants that completed 50% or more of EMA surveys post-treatment of all randomized participants
Measured: Post-treatment during weeks 10 and 11 post-randomization
Dimensions of Treatment Acceptability
Single-items measuring ratings of acceptability dimensions for the digital treatment, including willingness to engage, usability, understandability, engage-ability, visual appeal, helpfulness, skill acquisition, and confidence implementing skills. Scores for each item range from 1 to 5, with higher scores indicating better acceptability.
Measured: Ratings made at the post-treatment assessment, which is approximately 9 weeks after randomization
Secondary outcomes (4)
Change in Percent Days of Any Substance Use
The Timeline Follow Back, a calendar-based interview, will be used to assess substance use. A T-statistic of 0 indicates no change; more positive scores indicate a better outcome.
Measured: Baseline, at end-of-treatment (end of week 8 post-randomization) and at the 2-month follow-up period (weeks 9 to 16 weeks post-randomization)
Change in Percent Days of Primary Substance Use
The Timeline Follow Back, a calendar-based interview, will be used to assess substance use. A T-statistic of 0 indicates no change; more positive scores indicate a better outcome.
Measured: Baseline through end-of-treatment (end of week 8 post-randomization) and through the 2-month follow-up period (weeks 9 to 16 weeks post-randomization)
Change in Substance-related Problems
Short-inventory of problems Revised (SIP-R), a self-report questionnaire of substance-related problems. Total score range from 0 to 51, with higher scores indicating greater substance related problems. A T-statistic of 0 indicates no change; more positive scores indicate a better outcome.
Measured: Baseline through end-of-treatment (end of week 8 post-randomization) and through the 2-month follow-up period (weeks 9 to 16 weeks post-randomization)
Change in Brief Symptom Inventory (BSI) Score
BSI assesses psychiatric distress using a 5-point Likert scale, ranging from 0 ("not at all") to 4 ("extremely"). Higher scores indicate more distress. A T-statistic of 0 indicates no change; more positive scores indicate a better outcome.
Measured: Baseline through end-of-treatment (end of week 8 post-randomization) and through the 2-month follow-up period (weeks 9 to 16 weeks post-randomization)
