Personalized Support Using Instant Messaging Applications to Increase

Status Recruiting

Clinical Trial Summary

This study aims to assess the effect of personalized support using instant messaging application on smoking cessation in smokers proactively recruited from smoking hotspots in Hong Kong.

Clinical Trial Description

Detailed Description: With the advancement of information communication technologies (ICTs), instant messaging applications (IM Apps, e.g. WhatsApp and WeChat) can be used for providing synchronous, personalized, interactive interventions for health promotion. This study proposes to apply IM Apps for enhancing our tested brief smoking cessation (SC) intervention model from AWARD to e-AWARD (AWARD: Ask, Warn, Advise, Refer, Do-it-again,) without medications to increase SC in smokers proactively recruited in smoking hotspots in Hong Kong. Such smokers are the majority and have low quit rate. IM Apps allows trained SC advisors to proactively deliver personalized SC advices, response to smokers' needs promptly, and provide psychosocial support. No similar trials are found in PubMed, Cochrane Library and trial registries (ClinicalTrials.gov & ISRCTN) (except the pilot trial of this study). The aims of this study are as follows:

1. To assess the main effect of the personalized support using instant messaging applications (Intervention) vs. Control group on biochemical validated smoking abstinence at 6-month and 12-month.

2. To assess the effects on self-reported past 7-day abstinence, 24-week continuous abstinence, smoking reduction, self-efficacy of quitting, intention to quit, quit attempts and SC medications and services use at 6-month and 12-month.

3. To identify the mediators, which can inform mechanisms of the intervention on SC.

4. To evaluate the cost-effectiveness of the above interventions.

5. To understand the effects subjects' experience of IM support on SC using a qualitative study approach. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
