Chatbot Intervention to Reduce Common Digital Addictions, Sedentary Behaviors and Mental Distress Among Adolescents

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.
