About this trial
This study will develop and evaluate a smartphone-based behavioral intervention for adolescents with Attention-Deficit Hyperactive Disorder (ADHD) and smartphone overuse in Hong Kong. The main questions it aims to answer are:
* Can a smartphone-based intervention lower self-reported smartphone dependence and objective smartphone usage? * Can a smartphone-based intervention lower parent-rated and self-rated ADHD symptoms? * Are there differences in electroencephalogram (EEG) in the smartphone salient vs smartphone non-salient conditions after intervention?
Adolescent participants will:
* report weekly smartphone use patterns based on app screencap for 12 weeks * complete online surveys on smartphone dependency and ADHD symptoms for 3 times * receive 10-minute EEG recordings to gather resting-state EEG data in a natural and relaxing state for 3 times
Parent participants will:
* provide a valid clinical report to confirm the adolescent's diagnosis of ADHD * complete online surveys to report on the adolescent's smartphone usage and ADHD symptoms for 3 times
