The goal of this clinical trial is to assess the effectiveness of the Digi-Coach chatbot for reducing physical and psychological distress in people undergoing radiotherapy for head and neck cancer. The main question it aims to answer is: How effective is the Digi-Coach chatbot in reducing physical and psychological distress? Researchers will compare Digi-Coach chatbot to usual nursing care to see if Digi-Coach chatbot is effective for reducing physical and psychological distress in people undergoing radiotherapy for head and neck cancer. Participants will have access to the Digi-Coach chatbot during radiotherapy in addition to usual care. The research nurse will provide training on how to navigate the chatbot and ask participants to query all their cancer-related concerns in the chatbot.
