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.
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.

the TOVA API
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.

The ADHD-Rating Scale
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)
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
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.
