About this study
This study will test whether a peer-delivered intervention for high school students with ADHD outperforms enhanced school services as usual. Ninth grade students with ADHD (N=72) will be randomly assigned to the intervention (summer STRIPES) or the enhanced school services control group (SSU plus). Students will be assessed in the spring of 8th grade, fall of ninth grade, and spring of ninth grade. Primary outcomes will be GPA, Class Attendance, and ADHD symptoms (parent and teacher report).
Read the detailed description
The proposed study will adapt and test a low resource school-based intervention to prepare students with ADHD for the transition to high school-a point of vulnerability for youth with ADHD. The resulting intervention will be delivered as a peer-delivered orientation to high school (1-2 weeks for 4 hours a day) with weekly peer-delivered support during the first 16 weeks of the ninth grade year. Intervention development will involve scaling down an intensive Summer Treatment Program for adolescents with ADHD, using its core components (i.e., daily skills training and repetition, parent coaching in contingency management, engaging recreational activities) to bolster a promising peer-delivered school-based intervention for ninth graders with ADHD. The resulting intervention (summer STRIPES) will target three mechanisms that are critical markers of high school success: (a) intrinsic motivation, (b) extrinsic motivation, and (c) executive functions (EFs). Y01, will use a stakeholder informed process to iteratively adapt the intervention with input from two partnering high schools (i.e., administrators, counselors, teachers, parents, students) and content experts (Sibley, Langberg, Sasser, Aaronson). Two manuals that are individualized for each school will emerge. A total of 72 rising ninth grade students with ADHD will be recruited in Y02 and Y03 (36 per year; 18 per school) from two high schools randomly assigned (within school) to receive summer STRIPES or enhanced school services as usual (SSU plus). A school staff summer STRIPES sponsor at each school will oversee training and supervision peer interventionists with support from investigators. Peer interventionists will receive a three-day training and weekly supervision. Study assessments will occur at baseline and three follow-up points throughout the ninth grade year. To test the intervention's preliminary effectiveness, the study will examine treatment effects on GPA, class attendance, and disciplinary incidents. Preliminary effectiveness will also be measured through indices of engagement (parent, adolescent, peer attendance, ratings of satisfaction, perceived utility, and therapeutic alliance) and school fit (treatment fidelity, peer attitudes toward treatment). To detect whether therapeutic mechanisms (intrinsic motivation, extrinsic motivation, EFs) are engaged by summer STRIPES, the investigators will test for group differences on multi-method indices of these mechanisms, as well as the extent to which hypothesized mechanisms affect meaningful change on study outcomes. This project represents the first attempt to utilize a peer-delivered model for ADHD intervention in a high school orientation context. If summer STRIPES participants show meaningful improvements in functioning and engagement and school fit are strong, an R01 will be planned to fully evaluate the effectiveness of this approach. To inform this future trial, attention will be given to developing an optimal measurement battery, treatment delivery model, and recruitment strategy for rising ninth graders.

Enhanced School Services as UsualOther
Also called SSU plus
see arm description.
| Study group | Role | What they receive |
|---|---|---|
| Summer STRIPES | Experimental | Up to two weeks of daily high school orientation (four hours per day) immediately prior to the start of ninth grade, staffed by peer interventionists (2:1 ratio + extra interventionist in case of absences) and a school staff member. Two sessions of summer parent training. During the school year, ninth grade students will continue to meet weekly with their peer interventionists in a group setting under the supervision of the school staff sponsor. School year follow-up component of summer STRIPES will occur for 16 weeks and will include weekly 30 minute meetings between peer and target students. Parent components during the school year will include optional monthly group problem solving sessions with the school staff sponsor and school mental health liaison and a weekly phone call (up to five minutes) from the school staff sponsor to discuss home contingency management. Receives: Behavioral: Summer STRIPES |
| Enhanced School Services as Usual | Active comparator | Students who are assigned to the SSU plus group will be referred to their identified school counselor for referral to services available in the school setting. The counselor will be provided with a report from the student's intake assessment that summarizes the student's symptoms and presenting problems. The student will also receive new school supplies at the beginning of ninth grade. In our past trials, SSU plus students typically received subject-specific tutoring or after-school homework help. We will systematically track services received by students in the SSU plus condition. Receives: Other: Enhanced School Services as Usual |
What is being measured
The primary outcome is the main question the study is designed to answer.
Grade Point Average
Report cards were obtained directly from schools. GPA for each quarter was calculated by converting academic grades (e.g., English, Math, Science, Social Studies) to a 5-point scale (i.e., 4.0=A to 0.0=F). Grades were not weighted for class difficulty.
Measured: Change from Baseline to End of 9th grade, an average of 1 year
Class Attendance
Number of Class Absences per Academic Quarter
Measured: Change from Baseline to End of 9th grade, an average of 1 year
Attention Deficit Hyperactivity Disorder Symptom Severity
Parent and Teacher Rated ADHD Symptoms on DSM-5 ADHD Checklist, 0=minimum, 3=maximum, Higher score means worse outcome
Measured: Change from Baseline to End of 9th grade, an average of 1 year

Questions about this trial
What is this clinical trial studying?
A study testing Summer STRIPES and Enhanced School Services as Usual in people with ADHD, run by Seattle Children's Hospital at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 5 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 5 Mar 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Grade Point Average (time frame: Change from Baseline to End of 9th grade, an average of 1 year). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04571320, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Mar 2026.
