About this study
Official title: Mobile Phone Based Personalized and Interactive Augmented Reality (AR) Pictures on Enhancing Brief Advice Model for Smoking Cessation: a Pilot Randomized Controlled Trial
This pilot randomized controlled trail aims to test the effects of AR enhanced pictorial effects in harms of smoking and benefit of smoking cessation.
Read the detailed description
Conventional health warnings on smoking harms mostly include pictures showing smoking consequences such as lung diseases, peripheral vascular diseases, aging, skin lesions, and benefit of quitting such as improved cardiopulmonary functions, skin conditions and risk of diseases, etc. The effects of the information are limited by the generic messages, unattractive images, and lack of interaction. This proposal aims to enhance the "Warn" and "Advice" materials using mobile phone-based augmented reality (AR) technologies to provide personalized, interactive, and attractive images to encourage smokers to quit smoking.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Brief AWARD advice and active referral to somking cessation servicesBehavioural
The AWARD advice includes: (1) Ask about smoking history; (2) Warn about the high risk of smoking; (3) Advise to quit or reduce smoking as soon as possible; (4) Refer smokers to smoking cessation services (with a referral card); (5) Do it again: to repeat the intervention.
Chat-based support through Instant Messaging appsBehavioural
Participants in the intervention group will receive 3 months of chat-based support through Instant Messaging apps (e.g., WhatsApp, WeChat). The support mainly includes (1) regular messages on health warnings, benefits and methods of quitting, coping craving approach, and promotion to use the SC services; (2) real-time, personalized, and interactive behavioral and psychosocial support through Instant Messaging apps.
