What this trial studies
This intervention aims to evaluate the effectiveness of a self-determination theory-based approach combined with instant messaging to assist smokers diagnosed with cancer in quitting smoking. Participants will be allowed to choose their quit schedule and will receive regular instant messaging support. The study will involve a randomized controlled trial with 1448 smokers attending outpatient clinics at five major acute care hospitals in Hong Kong. The intervention includes a brief advice session using the AWARD model, followed by follow-up support through instant messaging.
Who should consider this trial
Good fit: Ideal candidates are smokers aged 18 and above, diagnosed with any stage of cancer, who can communicate in Cantonese and use instant messaging.
Not a fit: Patients with unstable medical conditions, poor cognitive states, or mental illnesses may not benefit from this intervention.
Why it matters
Potential benefit: If successful, this approach could significantly improve smoking cessation rates among cancer patients, enhancing their quality of life.
How similar studies have performed: Previous studies using similar self-determination and brief intervention approaches have shown promising results in smoking cessation.
