Spanish-language Executive Function Intervention for Children With Autism and/or ADHD

The goal of this clinical trial is to learn whether the Spanish-language version of Unstuck and On Target (SL-Unstuck), an executive functioning (EF) intervention, is feasible, acceptable, and effective for Spanish-speaking caregivers and their neurodivergent children (ages 8-11) in the U.S.. The main questions it aims to answer are: * Is SL-Unstuck acceptable to Spanish-speaking caregivers and children? * Does SL-Unstuck improve child EF, caregiver EF knowledge, and caregiver strain? Researchers will compare families randomly assigned to immediate SL-Unstuck versus waitlist control to see if participating in the intervention improves EF and family outcomes. Participants will: * Attend 8 weekly SL-Unstuck sessions at a clinic (parallel child and caregiver groups) * Complete pre- and post-intervention assessments on child EF, caregiver strain, and satisfaction * Participate in a focus group to share feedback on the intervention

Central Executive Training and Parent Training for ADHD

The goal of the current project is to combine two evidence- based treatments for school-aged children with ADHD: Central Executive Training (CET) and Behavioral Parent Training (BPT). CET is a computerized training intervention that improves ADHD symptoms and academic functioning by improving children's working memory abilities. BPT is a therapeutic intervention that improves family functioning and child oppositional-defiant (ODD) symptoms by changing parenting behaviors. Their combined use is expected to provide complementary and additive benefits, particularly if CET is delivered before BPT.

ADHD&me: Targeting Self-esteem in Youth With ADHD

The goal of this clinical trial is to learn whether the ADHD\&me (ADHD\&ik) intervention can improve self-esteem in youth aged 16-25 years with Attention Deficit Hyperactivity Disorder (ADHD). The ADHD\&me program is a cognitive behavioral therapy (CBT)-based intervention designed to help people with ADHD to develop a more positive view of themselves in their transition to adulthood. The main questions it aims to answer are: * Does the ADHD\&me intervention improve self-esteem in youth with ADHD, and are these effects maintained over time? * Does the intervention also improve related outcomes, such as masking of ADHD-related behaviors and co-occurring mental health symptoms including anxiety, depression, and stress? In this RCT, participants are assigned either to immediate treatment or to a waitlist control condition, with the latter receiving the intervention after an eight-week delay. Participants will: * Take part in seven individual therapy sessions according to the ADHD\&me intervention. * Complete questionnaires about self-esteem, masking of ADHD-related behaviors, ADHD symptoms, and co-ccurring mental health symptoms at several time points. * Complete short daily assessments (ecological momentary assessment) during one week at the start of the study and one week after the intervention or waitlist period to report momentary self-esteem, emotions, distress, and activities.

Testing a Measurement Feedback App to Improve Data Quality, Supervision & Outcomes in Behavioral Health

The goal of this clinical trial is to test whether a smartphone-based data collection and feedback application ("Footsteps") improves the quality of behavioral data collected by one-to-one aides and leads to better youth mental health outcomes in school-aged youth (ages 4-17) who receive one-to-one support in schools. The main questions it aims to answer are: 1. Does the Footsteps app improve aides' data collection quality (i.e., consistency, timeliness, and completeness)? 2. Does Footsteps use lead to improved youth behavioral health outcomes (e.g., SDQ, YTP, GAS scores)? 3. Does Footsteps improve communication and supervision processes between aides and clinical supervisors? Researchers will compare aides using Footsteps to those using a "data collection only" control app to see if Footsteps leads to higher quality data collection, enhanced supervisory communication, and better youth outcomes. Participants will: * Use either Footsteps or a control app to record de-identified data on one client's behaviors and skills over 12 weeks * Complete biweekly online surveys about data collection experiences, youth progress, and aide-supervisor communication * Participate in a virtual intake and post-trial meeting * (For a subset) Participate in a 30-45 minute qualitative interview about their experience using the app

Identification of Early Biomarkers of Pre-school ADHD

ADHD affects around 5% of children and manifests itself as hyperactivity, attention difficulties and motor control and balance problems. The prevalence of ADHD is particularly high in certain populations, affecting up to 25-30% of children born prematurely and around 20% of children with neurological conditions such as epilepsy. This disorder is officially diagnosed from the age of 6, according to current criteria. However, its clinical manifestations appear much earlier, having a significant impact on all aspects of the child's life, particularly in the most severe forms, which are often unrecognised due to a lack of clinical resources, and therefore without appropriate treatment. The creation of a platform dedicated to children at risk of ADHD will enable specific clinical expertise to be developed, with the aim of proposing early targeted interventions and positively influencing the development of their trajectory. This platform will also aim to develop new diagnostic methods, based on indirect measures of attentional and executive processes, balance and the development of a risk measurement scale. This development is essential, as the assessment tools currently available lack specificity. In order to demonstrate the reliability of the innovative diagnostic methods proposed, a comparative pilot study between children from the first clinical cohort (N=30) and a group of healthy children of the same age (N=30) will be carried out. This will enable us to study the discrimination of our tools and make any necessary adjustments. This pilot study also includes a longitudinal re-evaluation, at 12 months, of the children in the ADHD cohort, in order to study changes in these biomarkers over time.

Improving ADHD Symptoms and Quality of Life Through Diet

The goal of this randomised controlled trial is to evaluate whether a specific dietary intervention can reduce core symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD) in adults aged 18 to 50 years. The study also aims to understand how changes in diet may influence quality of life, neurocognitive function, and gut-brain signaling through the microbiota. The main questions it aims to answer are: 1. Does a high-fiber, fermented food-based diet reduce ADHD core symptoms over a 12-week period, as measured by the Conners' Adult ADHD Rating Scale (CAARS)? 2. Does the diet improve neurocognitive function, mood, food reward, individual goals, and other quality-of-life outcomes? 3. How does the diet affect gut microbial composition, inflammation, and stress-related biomarkers? 4. Is the diet well-accepted and feasible to follow? Researchers will compare a combination intervention diet (high in fiber and fermented foods) to a control diet based on general healthy eating guidelines to assess differences in symptom improvement and biological outcomes. Participants will: 1. Complete six study visits over a 24-week period (screening, baseline, weeks 4, 8, 12, and optional follow-up at week 24). 2. Be randomly assigned to one of two dietary groups after baseline assessments. 3. Provide stool, saliva, urine, and blood samples at multiple timepoints. 4. Undergo cognitive testing and EEG recording to assess brain function. 5. Wear a wristband to track sleep and activity patterns. 6. Use a nutrition app to log dietary intake and receive weekly dietary support. 7. Complete validated questionnaires on ADHD symptoms, mood, eating behavior, gastrointestinal health, sleep, and lifestyle factors. Feasibility and acceptability of following the diet will also be self-reported. This study includes both adults diagnosed with ADHD and matched controls without a psychiatric condition to better understand the mechanisms and potential differential responses to dietary intervention.

Fidgeting and Attentional and Emotional Regulation in ADHD

This project will study how fidgeting relates to cognitive and emotional functioning in adults with attention-deficit/hyperactivity disorder (ADHD). It will determine, in a laboratory setting, whether movement and access to a "fidget device" providing sensory and motor stimulation can improve cognitive and emotional regulation (including on physiological measures) in adult ADHD. The investigators will also acquire pilot data for machine learning analyses to be used in future, large scale studies to identify gestures and touch characteristics associated with improved cognitive and emotional regulation to see if the data can predict and subsequently develop recommendations to improve performance and emotional control in natural settings (e.g., home, office, college classroom) for adult ADHD.

Digital Health Intervention for Children With ADHD

To conduct an RCT to evaluate the efficacy of the system, we will recruit 60 children (ages 8-12) with ADHD who will be randomized to either immediate (n=30) or delayed (n=30) treatment (i.e., a wait-list control group). Among those randomized to immediate treatment, half will be assigned to DHI (delivered via a smartwatch and smartphone application) and half will be assigned to an active control treatment as usual (TAU) group who will receive the smartwatch with no assigned activities, applications, or interventions on the devices. The intervention period will last 16 weeks; after a participant has been in the delayed treatment group for 16 weeks and has completed the post-waiting period assessment, he or she will be assigned to either the intervention or active control group. Thus, 30 participants will complete the intervention and 30 will complete the active control, with half of the total sample also completing a wait-list period.

Comparative Efficacy of Organizational Skills Training (OST) and Mindfulness-Based Intervention (MBI)

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.
