Interventions

Instant Messaging IMBEHAVIORAL

Smokers can communicate with counsellors in real-time through instant messaging (social media). Our counsellors will trigger the conversation and invite the smokers to response after initial contact. Counsellors will keep contact with the smokers to offer help, positive encouragement, reflections and reminders about SC according to smokers' personal needs and to encourage them to seek SC services. Details of successfully booked SC appointment (e.g. SC services address, contact information, date, appointment number etc.) will be delivered to the smokers using IM. All smokers will receive a reminder-to-attend IM messages 1-3 days before the appointment date.
