Outcome Measures

Primary Outcomes (1)

  • K-BRIEF-2 (Behavior Rating Inventory of Executive Function, Second Edition)

    The K-BRIEF-2 consists of 63 items rated on a 3-point scale (Never, Sometimes, Often). The K-BRIEF-2 comprises 9 scales (Inhibit, Self-Monitor, Shift, Emotional Control, Initiate, Working Memory, Plan/Organize, Task-Monitor, Organization of Materials) organized under 3 index scores (Behavior Regulation, Emotion Regulation, Cognitive Regulation). The 9 scales collectively yield the Global Executive Composite (GEC), which reflects overall executive functioning. Higher T scores indicate greater executive function difficulties.

    Baseline (V2,V4), Day 42 (V4,V6)

Secondary Outcomes (9)

  • K-ARS-5 (Korean ADHD Rating Scale, 5th Edition)

    Baseline (V2,V4), Day 42 (V4,V6)

  • K-VABS-II (Korean Vineland Adaptive Behavior Scales-II)

    Baseline (V2,V4), Day 42 (V4,V6)

  • KAT (Korean Attention Test System)

  • Participant and parent (or legal guardian) voluntarily decide to join the trial and provide written informed consent
  • Participants willing to comply with the clinical trial procedures

You may not qualify if:

  • A risk of clinically significant behavioral problems, emotion regulation problems, psychotic symptoms, self-harm, or other harm at a level that affects the treatment process
  • Severe acute/chronic medical or mental illness
  • Serious trauma or surgery performed within 4 weeks before the screening date
  • Participants with other disabilities such as severe neurological diseases (e.g. brain lesions, mental disorders, etc.)
  • Participants who are currently participating in another clinical trial or have participated in another clinical trial within 30 days before the screening date
  • Change in the dosage or regimen of medications that may significantly affect cognitive function within 4 weeks prior to the baseline visit
  • Change in participation in treatment/education/rehabilitation programs that may significantly affect cognitive function within 4 weeks prior to the baseline visit
  • Participation in a clinical trial of, or prior experience using, cognitive improvement or daily living improvement software within 12 weeks prior to the baseline visit
  • In other cases where the investigator determines that participation in the clinical trial is inappropriate due to ethical reasons or the possibility of influencing the results of the clinical trial
