- The University of Hong Kong
- Brief Summary
The study aims to explore the effectiveness of neurofeedback training on improving attention and inhibitory control of children with attention-deficit/hyperactivity disorder (ADHD) in Hong Kong. This study will contribute to the current understanding of the alternative treatments for ADHD, and hopefully help to mobilize more resources to support children with ADHD. The programme includes the following components:
Participants will be randomly assigned to the neurofeedback training group (with virtual reality \[VR\] technology applied), the computerized cognitive training group, or the waitlist control group. All participants will complete a total of 16 training sessions in 8 weeks (twice a week), and each session will last around 35 to 60 mins.
To investigate the intervention effectiveness, children will be asked to complete a set of cognitive tests covering inhibitory control, attention, and working memory prior to the intervention (i.e., Time 1), immediately after the 8-week training (i.e., Time 2), and 2 months after the training (i.e., Time 3, a 2-month follow up). The assessment will take around 1 hour and it will be conducted at the laboratory at the University of Hong Kong. Also, parents and teachers will be asked to complete a questionnaire assessing children's behaviours at home and schools at 3 timepoints.

Group Intervention Description Active Control Group: Computerized Cognitive Training Group Computerized Cognitive Training The computerized cognitive training group will receive 16 sessions of training, 35 minutes each, conducted twice per week over a period of 8 weeks. Participants will be asked to complete a set of computerized tasks using Cogmed, a digital training programme which is proven to enhance working memory and attention level in children. Waitlist Control Group Computerized Cognitive Training The waitlist control group will not receive any intervention until the intervention arms complete their training. Depending on the availability, either the fNIRS Neurofeedback-VR Training or the Computerized Cognitive Training will be offered to this group. Experimental Group: fNIRS Neurofeedback-VR Training Group fNIRS Neurofeedback-VR Training The experimental group will receive 16 sessions of training, 1 hour each, conducted twice per week over a period of 8 weeks. A classroom setting will be stimulated using VR and participants will be asked to complete some academic-related tasks during the stimulated lessons. The sensor on the neurofeedback device worn by the participants will detect changes in the blood oxy-hemoglobin level in brain cortical tissue and feedback to the participants via visual images or auditory sounds from the computer. Through practice, participants will learn to manipulate their attention, presumably by altering brain activities. Waitlist Control Group fNIRS Neurofeedback-VR Training The waitlist control group will not receive any intervention until the intervention arms complete their training. Depending on the availability, either the fNIRS Neurofeedback-VR Training or the Computerized Cognitive Training will be offered to this group.
- Primary Outcome Measures
Name Time Method Conners Continuous Performance Test 3rd Edition (CPT 3) Delayed Post-intervention Assessment (a 2-month follow up after the completion of the intervention) A standardized computerized test on sustained attention and inhibitory control
Creature Counting subtest of the Test of Everyday Attention for Children (TEA-CH) Delayed Post-intervention Assessment (a 2-month follow up after the completion of the intervention) A measure of attentional control and switching that requires children to repeatedly switch between two simple activities, counting upward and counting downward.
Number subtest of Children's Memory Scale (CMS) Delayed Post-intervention Assessment (a 2-month follow up after the completion of the intervention) A verbal working memory test using digit span, with a higher score indicating a higher level of verbal working memory. The total score of this test ranges from 0 to 30.
Opposite Worlds subtest of the Test of Everyday Attention for Children (TEA-CH) Delayed Post-intervention Assessment (a 2-month follow up after the completion of the intervention) A measure of attentional control/switching that requires the child to make cognitive reversals.
Functional NIRS Delayed Post-intervention Assessment (a 2-month follow up after the completion of the intervention) The levels of oxygenated and deoxygenated hemoglobin of the prefrontal cortex will be measured throughout the training sessions and direct assessments using functional NIRS.
- Secondary Outcome Measures
Name Time Method Behavioural ratings on children's executive functions Delayed Post-intervention Assessment (a 2-month follow up after the completion of the intervention) Parents and teachers will be asked to complete Behavior Rating Inventory of Executive Function, Second Edition (BRIEF2) measuring a range of executive functions, including behavioural, emotional and cognitive regulation
Children's ADHD symptoms Delayed Post-intervention Assessment (a 2-month follow up after the completion of the intervention) Parents and teachers will be asked to complete the Swanson, Nolan, and Pelham Version IV Scale (SNAP-IV) measuring children's inattentive, hyperactive and impulsive symptoms with a 4-point Likert scale (ranges from 0 to 3). The minimum total score is 0 while the maximum total score is 78, with a higher score indicating a higher level of inattentive, hyperactive and impulsive symptoms.
