Brief Summary

The aim of this project is to promote and evaluate a smoking cessation intervention through the "Quit to Win" Contest organised in correctional institutions in Hong Kong. The aim of this project is to promote and evaluate a smoking cessation intervention through the "Quit to Win" Contest organised in correctional institutions in Hong Kong. The specific objectives of the study are:

  1. 1.To test the effectiveness of face-to-face brief cessation advice and video education for smoking cessation among current smokers at the correctional institutions in Hong Kong;

Outcome Measures

Primary Outcomes (2)

  • Biochemical validated quit rate at 6-month follow-up

    The primary outcome is biochemically validated quit rates (exhaled CO \< 4 ppm and salivary cotinine \< 10 ng/ml) at 6-month

    6-month follow-up

  • Biochemical validated quit rate at 3-month follow-up

    The primary outcome is biochemically validated quit rates (exhaled CO \< 4 ppm and salivary cotinine \< 10 ng/ml) at 3-month

    3-month follow-up

Secondary Outcomes (4)

  • Smoking quit rate change from baseline at 3-month follow-up

    3-month follow-up

  • Smoking quit rate change from baseline at 6-month follow-up

  • Smoking reduction rate change from baseline at 3-month follow-up

Study Arms (1)

Group A

EXPERIMENTAL

CSD participants will receive a combined intervention: 1. Brief intervention using AWARD advice at baseline, 2. Video-based health education

Behavioral: AWARD adviceBehavioral: Video-based health education

Interventions

AWARD adviceBEHAVIORAL

Ask about smoking history, Warn about the high risk of smoking, Advise to quit as soon as possible, Refer to the smoking cessation services, and Do it again (if the smokers refused to set quit date)

Group A
Video-based health educationBEHAVIORAL

Educational videos on smoking and health will be developed to improve the knowledge of CSD smokers. The videos aim to raise their awareness on these important health topics and acquire effective cessation methods. The effectiveness of the educational videos will be evaluated by pre- and post-tests through a self-administered survey that assess the changes in knowledge related to smoking hazards, benefits of quitting, and methods to quit smoking.
