• Registration Number: NCT06570070
• Lead Sponsor: Beijing Normal University

Brief Summary

This study aims to explore the feasibility and preliminary effectiveness of AI-powered chatbot support in community smokers.

Detailed Description

Smoking cessation remains one of the most significant public health challenges worldwide, with tobacco use being a leading cause of preventable death and disease. Despite extensive efforts, the success rates of smoking cessation programs remain low, necessitating innovative approaches to support individuals in their journey to quit smoking. Recently, artificial intelligence (AI) has opened new possibilities in healthcare, including the development of AI-powered chatbots that assist individuals in behavior change, such as quitting smoking.

This randomized controlled trial aims to investigate the effectiveness of AI-powered chatbot that simulates human counselors, compared to traditional human counseling in promoting smoking cessation among community smokers. The AI-powered chatbot, equipped with personalized interactions and real-time support, offers scalable and cost-effective assistance, potentially making it an accessible alternative to human counseling. However, human counselors provide empathy, tailored advice, and a nuanced understanding of human behavior that AI may not fully replicate. This study will explore which approach is more effective in helping individuals achieve long-term smoking cessation.
