About this study
Official title: Comparing Psychosocial Supports for Adolescents With ADHD: What Works Best for Whom and Why?
This randomized control trial comparing Organizational Skills Training (OST) and Mindfulness-Based Intervention (MBI) among adolescents with a pre-existing ADHD diagnosis presenting to the Duke ADHD Program.
Both treatments are eight 90 minute sessions.
The research component will involve a pre-treatment assessment and post-treatment assessment. Both assessments will involve adolescents and one caregiver to complete questionnaires over REDCap. Rating scales will include ADHD symptom severity (Conners 3: self and parent report), functional impairment (IRS: self and parent report), executive functioning (BRIEF-2: parent report), emotion dysregulation (DERS: self and parent report), trait mindfulness (FFMQ: self report), organizational skills (BRIEF-2: parent report), treatment satisfaction (self report and parent report) and credibility (self report and parent report). Post-treatment assessments for feasibility will include attendance (measured over the course of treatment) and homework completion rates on a scale of 1 to 5 in which 5 indicates higher homework completion. We will also assess acceptability via individual items on a Likert scale (self report): overall satisfaction, how much was learned about ADHD, usefulness of information learned, content relevance to individual experience, comprehension of strategies, confidence about using strategies, likelihood of using strategies, helpfulness to share with the group, benefits from hearing from other group members, willingness to recommend the same treatment to others, and whether or not treatment was beneficial.
Read the detailed description
This will be a randomized controlled trial in which incoming patients (N=36) who have been referred for ADHD psychosocial treatment at the Seattle Children's Behavior, Attention, Management clinic between ages 13-17 will be offered the opportunity to participate in this study.
If they wish to participate, they will be randomly assigned to receive the MAPA MBI or to receive Organization Skills Training (TOPS) at the clinic. Both groups will be 8-week, 90 groups that will run simultaneously via telehealth delivered by routine clinicians in the BAM clinic. Both groups will have one "pre-session" that parents join that explains the purpose of the group and what parents and teens can do to work together and support home practice of skills learned during the group. We will collect baseline and post-treatment ratings of outcome measures. There will be two cohorts (fall and winter and each cohort will enroll 18 youth for random assignment at a 1:1 ratio). Incoming patients who do not wish to participate in the study will still be eligible to enroll in standard psychosocial treatment groups at the BAM clinic that they would otherwise be eligible for (i.e., declining to participate will not delay the treatment they otherwise would receive in the clinic).

What is being measured
The primary outcome is the main question the study is designed to answer.
ADHD symptoms
Measured using the Conners 3 self and parent reports from the pre- and post- treatment questionnaires. Participants will rate several statements using a scale ranging from 0 to 3 (from Not True at All to Very Much True). Higher scores indicate more behavioral, emotional, or ADHD-related concerns.
Measured: From enrollment to the end of treatment at 8 weeks
Functional Impairment
Measured using the Impairment Rating Scale [IRS]: self and parent reports from the pre-and post-treatment questionnaires. Each item rated 0-6; total or mean scores vary by scoring method, with higher scores indicating greater functional impairment.
Measured: From enrollment to the end of treatment at 8 weeks.
Executive Functioning
Measured using Behavior Rating Inventory of Executive Functioning [BRIEF-2]: parent report from pre-and post-treatment questionnaires. Participants will rate several behaviors on a scale of 1-3 depending how often that behavior occurs. Higher scores indicate higher executive functioning difficulties.
Measured: From enrollment to the end of treatment at 8 weeks.
Emotion Dysregulation
Measured using Difficulties in Emotion Regulation Scale [DERS]: self and parent reports from pre-and post-treatment questionnaires. Each item on the DERS is rated using a 5-point Likert scale, with higher scores indicating greater difficulties with emotional regulation.
Measured: From enrollment to the end of treatment at 8 weeks.
Trait Mindfulness
Measured using the Five Facet Mindfulness Questionnaire [FFMQ]: self report given during the pre-and post-treatment questionnaires. Each item on the FFMQ is rated using a 5-point Likert scale, with a higher total score indicating greater mindfulness.
Measured: From enrollment to the end of treatment at 8 weeks.
Organizational Skills
Measured using the Behavior Rating Inventory of Executive Functioning (BRIEF-2): parent report given during the pre- and post- treatment questionnaires. Participants will rate several behaviors on a scale of 1-3 depending how often that behavior occurs. Higher scores indicate higher executive functioning difficulties.
Measured: From enrollment to the end of treatment at 8 weeks.
