Brief Summary

The prevalence of Attention Deficit/ Hyperactivity (ADHD) varies between 3 and 10% depending on the studies. Comorbidities are frequently associated, in particular anxiety disorders. School, social and family consequences of ADHD can be major, especially in the presence of a comorbidity. The study goal is to evaluate, through questionnaires, the effect of self-hypnosis via a smartphone application, on the symptoms of inattention and anxiety in children with ADHD in addition to their treatment by methylphenidate. Parents and children complete the study questionnaires four times.

  • T0: at inclusion
  • T1 (T0+6 weeks): after 6 weeks of using the self-hypnosis application 5 days out of 7 for group 1 in parallel with the usual treatment / after 6 weeks of usual treatment for the group 2
  • T2 (T0+8 weeks): after a wash-out period of 2 weeks (usual treatment only) for both groups
  • T3 (T0+14 weeks): after 6 weeks of use of the self-hypnosis application 5 days out of 7 for group 2 in parallel with the usual treatment / after 8 weeks of usual treatment for the group 1, following the 6 weeks of use of the application.

Outcome Measures

Primary Outcomes (1)

  • Change in severity of attention deficit

    The severity of attention deficit is assessed with the Conners 3 questionnary. It provide information's for information for 11 scales and includes 110 questions. Our research will focus on the T-score of inattention scale (mean=100, standard deviation=10). The higher the score is, the severed the symptom is. The change of the inattention scale T-score from base line at 6 weeks and 14 weeks will be used as primary outcome.

    Day 0, 6 weeks, 8 weeks, 14 weeks

Secondary Outcomes (2)

  • Change in severity of anxiety with a self-questionnaire

    Day 0, 6 weeks, 8 weeks, 14 weeks

  • Change in severity of anxiety with a hetero-questionnaire

    Day 0, 6 weeks, 8 weeks, 14 weeks
