Evaluating the Efficacy of a Text Messaging-based Shisha Smoking Cessation Intervention

The goal of this study is to evaluate the efficacy of a culture specific text-messaging based shisha smoking cessation intervention for young adults in Hong Kong. Participants in the intervention group will receive smartphone text messaging-based intervention and support that contained personalised messages with both text and visual elements over 6 weeks under a manualised programme. Participants in the control group will only receive a leaflet about the health risks of shisha smoking (the exact identical contents received by the participants in the intervention group at a session). All participants will complete a self-administered questionnaire at baseline, 6th- and 12th-week on their self-reported shisha abstinences, knowledge on risk, readiness to quit and attitudes on shisha smoking
