Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Hypothesis: The intervention group will show a greater reduction in rates of IGD and/or SMA at post-treatment and 3-month follow-up than the control group.
Design and subjects: A two-armed RCT between the intervention group and psycho-educational control group for adolescents aged 10-19 with excessive screen time. Screening, baseline, post-programme, and 3-month follow-up evaluations will be conducted.
Participants will:
Be randomly assigned to online brief intervention or psycho-educational control
Complete questionnaires evaluating 1 ) Primary outcomes (IGD, SMA), 2) Secondary outcomes (sedentary lifestyle, mental distress, quality of life, eHealth literacy) and 3) Mediators/mechanisms (autonomy, competence)

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Control
Participants will receive educational but not SoC and MI-based materials about excessive digital use, IGD, and SMA. Such psycho-educational interventions are widely used in behavioral/mental health promotion and have been demonstrated to be effective in increasing knowledge and awareness of behavioral and mental problems. Based on a comprehensive literature review and our previous psycho-educational programs for behavioral/mental health promotion, the research team will design the psycho-educational materials. Themes include definitions, factors, and health consequences of excessive digital use, IGD, and SMA, information on healthy lifestyles, self-regulation skills, and help-seeking resources.
Control
The intervention includes five modules based on the five stages of Stages of change. Chatbots will build up a rapport with the participants, monitor their stage with a few simple questions based on previous Stages of Change studies, and provide stage-tailored packages of response, advice, and feedback (one of the five modules) accordingly to enhance their motivation and self-efficacy each week. For those who click 'yes' to a question assessing the first stage of change (PC), Chatbot will make a record and automatically ask questions assessing the next stage; for those who click 'no', Chatbot will automatically send them the module corresponding to their SoC via WhatsApp. Each module will take 10-15 minutes. In total, it will take 1 hour to complete all the modules.
