Digital therapy
Brief summary
This study is designed to explore the effect of Multitask game-based digital therapy versus Schulte Grid digital game on attentional functioning (measured by the TOVA), ADHD symptoms, executive functioning, and clinical impairment, in children diagnosed with ADHD. Investigators will also evaluate the safety of digital therapy for intervention treatment of childhood attention deficit hyperactivity disorder.
Detailed description
ADHD is a common neurodevelopmental disorder characterized by a persistent pattern of inattention and/or hyperactivity and impulsivity, resulting in functional impairment in multiple settings.The prevalence in China is estimated to be 6.26%. Front-line intervention for ADHD includes pharmacological and non-pharmacological interventions, which have shown short-term efficacy.There are limitations to current best practices for the treatment of ADHD. Relating to pharmacotherapy, they are accompanied by adverse events in many children, do not normalize functioning , and adherence rates over time are generally low. Pharmacotherapy may not be suitable for some patients.Relating to non-pharmacological interventions, barriers to access limit the use of non-pharmacological interventions, given a shortage of properly trained paediatric mental health specialists and variability in insurance coverage for such services. Digital therapy for ADHD may address these limitations with improved access, minimal side-effects, and low potential for abuse.There are studies show that digital intervention can significantly increase attentional functioning of children with ADHD.At present, there are few related researches on digital therapy in China.The total number of ADHD children is large in China, and electronic products are very popular in Chinese families.If digital therapies suitable for ADHD children in China can be developed, it will be of great significance for the promotion of human health. Therefore, investigators designed the study to explore the effect of Multitask game-based digital therapy versus Schulte Grid digital game on attentional functioning (measured by the TOVA), ADHD symptoms, executive functioning, and clinical impairment, in children diagnosed with ADHD in China.Safety, tolerability, and compliance were also assessed. The study will be a blinded (investigators and outcome assessors), randomized, parallel group, follow-up study of the sustained effects of 28 days of treatment with either Multitask game-based digital therapy or Schulte Grid digital game. The trial will consist of 3 visits: Screening, FU-Day 14 visit and FU-Day 28 visit.

Inclusion criteria
* Age 8 years to 12 years, inclusive, at the time of parental informed consent. * Male or female. * Confirmed ADHD diagnosis , any presentation , at Screening based on DSM-V criteria and established via the MINI-KID administered by a trained clinician. * Screening/Baseline score on the clinician-rated ADHDRS-IV score 24. * Screening/Baseline score on the TOVA API -1.8. * Not undergoing pharmacological treatment with methylphenidate or amphetamine-based products at time of Screening ; or, if undergoing pharmacolog ical treatment , must be willing and appropriate (i.e. not optimally treated in the investigator's judgment) to wash out of current regimen. * Estimated IQ score\~ 80 as assessed by Wechsler Intelligence Scale for Children-Fourth Edition ,WISC-IV. * Ability to comply with all the testing and requirements.
Exclusion criteria
* Current, controlled (requiring a restricted medicatio n) or uncontrolled, comorbid psychiatric diagnosis , based on MINI-KID and subsequent clinical interviewing, with significant symptoms including but not limited to post-traumatic stress disorder , psychosis, bipolar illness, pervasive developmental disorder, severe obsessive compulsive disorder, severe depressive or severe anxiety disorder , conduct disorder , or other symptomatic manifestatio ns that in the opinion of the Investigator may confound study data/assessments . * Children who are currently at risk of suicide or have attempted suicide; children who have a history of suicide or are currently exhibiting active suicidal ideation or self-harm. * Unable to stop taking ADHD medication. * Motor condition (e.g., physical deformity of the hands/arms ; prostheses) that prevents playing the digital therapy as reported by the parent or observed by the investigator . * Recent history (within the past 6 months) of suspected substance abuse or dependence. * History of seizures (exclusive of febr ile seizures) , or significant motor or vocal tics, including but not limited to Tourette 's Disorder. * Diagnosis of or parent-reported color blindness. * Uncorrected visual acuity (Confirmed in-clinic via ability of subject to play the game). * With severe mental retardation. * Any other medical condition that in the opinion of the investigato r may confound study data/assessments.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| the TOVA API | Baseline | The primary outcome measure was the mean change in The Attention Performance Index (API) of TOVA. The TOVA is a validated, computerised, continuous performance test that objectively measures attention and inhibitory control, normalised by age and sex. The API is calculated from variability, response time, and d' (D Prime) using the following formula: API = Response Time Z score (Half 1) + d' Z score (Half 2) + Variability Z score (Total) + 1.80 API tells how similar the score is to the ADHD profile. A score of less than 0 indicates that the subject had similar performance to a normative ADHD population. A lower score indicates a more severe ADHD profile. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The ADHD-Rating Scale | Baseline | The ADHD-Rating Scale is an 18-item scale assessing the frequency of each ADHD symptom based on DSM-IV criteria. The scale consists of 2 subscales: inattention (9 items) and hyperactivity-impulsivity (9 items). Each item is scored on a 4-point scale ranging from 0 (rarely or never) to 3 (very often) with total scores ranging from 0-54. A higher score indicates more severe ADHD symptoms and behaviors. |
| The Clinical Global Impression Scale - Improvement (CGI-I) | 14 days after enrollment | The Clinical Global Impression Scale - Improvement (CGI-I) is a clinician's comparison of the participant's overall clinical condition at follow up to the overall clinical condition at baseline. The CGI-S is a 7-point scale where 1 = Very much improved, 2=Much improved, 3=Minimally improved, 4=No change, 5=Minimally worse, 6=Much worse, and 7=Very much worse. A score of 1, 2, or 3 would indicate overall improvement of ADHD severity. |
| BRIEF Inhibit Percentile | Baseline | The Behavior Rating Inventory of Executive Function (BRIEF) is a parent-rated form that assesses everyday behavior associated with specific domains of the executive functions of their child. The BRIEF working memory metacognition subscale measures the participants ability to hold information when completing a task in a sequential manner. A lower subscale score indicates better ability of working memory. |
| Adverse Device Effects | 14 days after enrollment | The expectedness of an ADE shall be documented in case Report Form（CRF）. 1. Dizziness,2. Nausea,3. Headache,4. Increased and unusual levels of frustration during game play. |
