Exercise Counseling Via Mobile Chat for Older Cancer Survivors

The 12 weeks of messages will be sent by a trained counsellor. At baseline, participants will select their desired IM application (WhatsApp/WeChat), timing of messages (morning/noon/afternoon), message format (audio/text), and language style (spoken/written). The message library, established in the HMRF-funded study, consists of messages in text and pre-recorded voice message formats, images, videos, and stickers. Each week starts with messages on factual information and ends with a question to initiate conversations to clear any queries; counsellor will provide real-time replies. The 12-week messages are structured based on the M-PAC framework.
