简要总结
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

研究组 & 干预措施
Smartphone Intervention
The treatment group will receive a 12-week individualized smartphone-based behavioral intervention based on the following strategies. They will be contacted once a week to collect the objective smartphone use patterns and check for compliance of the intervention strategies.
干预措施: Smartphone-based behavioral intervention (Behavioral)
Control
The control group will receive information about the known benefits and risks of SO and activate their smartphones' screentime monitoring setting. They will be contacted once a week to collect the objective smartphone use patterns, but they will self-monitor their smartphone usage.
干预措施: Self-monitoring of smartphone use (Other)
结局指标
主要结局
Number of notifications
时间窗: Baseline, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 weeks, and 12 months
Objective smartphone use data will be collected via smartphone apps (e.g., "ScreenTime" on Apple or "Digital Wellbeing" on Android) to trace the pattern of smartphone use of each participant. Participants will send screenshots of the number of notifications received over the previous 7 days on their phones.
Smartphone dependence
时间窗: Baseline, 13 weeks, and 12 months
To allow for comparisons with existing studies, we will use the Smartphone Addiction Scale - Short Version validated in Hong Kong, which was designed for the assessment of smartphone dependence and showed good reliability and validity. The scale has ten items, such as "Missing planned work due to smartphone use" and "I will never give up using my smartphone even when my daily life is already greatly affected by it". Each item was measured by 6-point scales, from 1= "strongly disagree" to 6 = "strongly agree". Total score on the scale will be used to assess the degree of each participant's smartphone dependence, with suggested cut-off values of smartphone overuse for male and female was 31 and 33, respectively.
Minutes of smartphone use
时间窗: Baseline, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 weeks, and 12 months
Objective smartphone use data will be collected via smartphone apps (e.g., "ScreenTime" on Apple or "Digital Wellbeing" on Android) to trace the pattern of smartphone use of each participant. Participants will send screenshots of the minutes of smartphone use over the previous 7 days on their phones.
Categories of smartphone use
时间窗: Baseline, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 weeks, and 12 months
Objective smartphone use data will be collected via smartphone apps (e.g., "ScreenTime" on Apple or "Digital Wellbeing" on Android) to trace the pattern of smartphone use of each participant. Participants will send screenshots of the distribution of minutes spent according to categories of use (social networking, games, entertainment, productivity, etc.) over the previous 7 days on their phones.
Number of screen unlocks or "pickups"
时间窗: Baseline, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 weeks, and 12 months
Objective smartphone use data will be collected via smartphone apps (e.g., "ScreenTime" on Apple or "Digital Wellbeing" on Android) to trace the pattern of smartphone use of each participant. Participants will send screenshots of the number of screen unlocks or "pickups" over the previous 7 days on their phones.
次要结局
- ADHD symptoms(Baseline, 13 weeks, and 12 months)
- Resting-state EEG frequency(Baseline, 13 weeks, and 12 months)
