Attention Deficit Disorder With or Without Hyperactivity (ADHD)

This study will evaluate if a specific treatment for emotion regulation in ADHD, GEARS, effectively reduces symptoms of emotional dysregulation. GEARS will be evaluated through a randomized controlled trial (RCT) and a qualitative interview study. This project aims to investigate two main questions: 1. Is GEARS an effective treatment for emotion regulation difficulties in adult ADHD patients? 2. How do participants perceive the impact of completing the GEARS treatment? Study 1 investigates research question 1 through an RCT comparing GEARS to a passive control group. Data are collected using validated measures before and after treatment/waiting period, as well as at six and 12 months follow ups. Sample size: 150 participants, ensuring sufficient statistical power to detect significant between-group differences, even with some attrition. Study 2 examines the patients' perspectives on the treatment by interviewing 15-20 participants about their experience with GEARS. The interviews focus on GEARS' perceived impact. Interviews will be recorded, transcribed, and analyzed using thematic analysis to identify key recurring themes.

Attention Deficit Disorder with or without Hyperactivity (ADHD) is a neurodevelopmental disorder characterized by a triad of symptoms combining inattention, hyperactivity, and/or impulsivity. It causes developmental and functional disturbances (cognitive, behavioral, and emotional) that have a detrimental impact on the child's family, school, and/or social life. Treatment requires psychoeducation for the child and their parents, individual treatment for the child, and finally family treatment, particularly through specific parenting skills training programs (such as the Barkley program, 1997). It is sometimes necessary to combine this with medication (psychostimulants). This care pathway can be complex to implement in practice, due to lack of regional actors (CMPPs, medical-psychological-educational centers) and a decrease in the number of child psychiatrists in hospital services. Recently, digital applications enabling the digitization of the psychotherapeutic approach have been developed to complement and reinforce the care provided to these children, offering an immediately available non-pharmacological alternative. LUSHA is a digital application (digital game) developed in collaboration with healthcare professionals. It aims to motivate the children to change their behavior and help parents to interact with them. The goal of this observational study is to evaluate the adoption of LUSHA app by children with Attention deficit disorder with or without Hyperactivity (ADHD) and their parents : * The primary objective of this study is to assess adherence/use of a digital application among children with ADHD and their parents over a period of 90 days * The secondary objectives are to assess the clinical impact of the LUSHA digital application using validated questionnaires (i.e quality of life, behavioural, family functioning). Participating children and their parents will be asked to use the LUSHA digital application during 3 months and to answer online surveys.

The aim of this protocol is to disentangle the links between symptoms of emotion dysregulation, sleep disorders and cognitive deficits by measuring the effects of an emotional induction task on childrens' sleep with autism spectrum disorders (ASD) and attention deficit hyperactivity disorder (ADHD).
