Low-intensity Ecological Momentary Assessment (EMA) for Smoking Cessation Intervention and Tobacco Control Policy Evaluation: a Randomized Controlled Trial Nested Within an EMA-based Observational Study

The University of Hong Kong·interventional·Posted Jan 28, 2022·Updated Jan 3, 2025

In Brief

A clinical study evaluating EMA-based intervention for Smoking Cessation. Completed, enrolled 459 participants across 1 site.

Detailed Summary

The EMA-based intervention in this proposal is aimed to motivate the majority of smokers who do not prefer to use traditional cessation aids for quitting and help them quit smoking. The smartphone application (app) and the EMA-based phone reminders at low cost and short intervention time make this approach attractive for the majority of smokers. Identification of accurate and specific pro-smoking cues in the real-word and real-time environmental cues via the app will provide valuable information to guide new tobacco control policies.

Interventions

EMA-based interventionbehavioral

A personal quit plan includes (1) self-help techniques on handling craving; (2) suggestions to avoid the reported pro-smoking cues; (3) whether to quit progressively or abruptly; (4) referral for existing smoking cessation service; and (5) instruction of using over-the-counter (OTC) nicotine replacement therapy (NRT), if OTC-NRT is preferred by the participant will be designed and give to the participants via a nurse-led phone call.

EMA-based interventionbehavioral

Participants will receive 10-week tailored quitting reminder instant messages via WhatsApp and voluntarily discuss their quit plan with the research staff.
