The "Quit-for-Kids" Project: to Increase Abstinence and Protect Children From Tobacco Smoke Exposure

Summary

This project aims to test the effectiveness of an integrated intervention of brief cessation advice (AWARD), Nicotine Replacement Therapy, and Instant Messaging support compared with waitlist control participants among adult daily smokers who lived with their children and non-smoking partners.

Conditions

• Second Hand Tobacco Smoke

Interventions

BEHAVIORAL

Brief cessation advice (AWARD)

DRUG

Nicotine Replacement Therapy (NRT)

1-week sampling of Nicotine Replacement Therapy (NRT) will be provided to support quit attempt. Full pharmacological treatment (12-week) will be available if needed.

BEHAVIORAL

Instant messaging Support (IM)

Chat-based mHealth personalized psychosocial and behavioural counselling (smoking cessation and SHS exposure reduction messages will be derived from previously tested interventional studies) using baseline children health and biofeedback data to support quitting throughout the intervention period of 3 months.

BEHAVIORAL

Financial Incentive (FI)

A financial incentive (vouchers) of HK$ 500 will be provided for biochemically validated smoking abstinence at 3- and 6-month follow-up. Considering a possibly low engagement rate of the smokers in mHealth-based support (17% in our previous trial, non-engagement mostly due to busy work), additional HK$ 200 will be provided for participants who actively engaged in the mHealth counselling (defined by have discussed quitting process for \>2 times) at 3-month follow-up.

A well-designed self-help booklet will be provided to guide and provide detailed information on smoking cessation. The contents include information about the benefits of quitting, smoking and diseases, methods to quit, how to handle withdrawal symptoms, declaration of quitting, etc.

BEHAVIORAL

Environmental assessment derived intervention

In a selected subgroup of 50 families with an additional signed consents, four home visits will be done to: 1. Setup an indoor air quality (IAQ) monitor to collect 24hr air quality data (2 weeks), 2. Collect the monitor for data retrieval, 3. Setup the monitor at 6 months follow-up (2 weeks), 4. Collect the monitor for data retrieval.
