JRCT ID: jRCT1030230169

Registered date:25/06/2023

Basic Information

• Recruitment status: Complete
• Health condition(s) or Problem(s) studied: Smoking Cessation
• Date of first enrollment: 25/06/2023
• Target sample size: 200
• Study type: Interventional

Intervention(s)

The study will measure the effectiveness of smoking cessation in a randomised controlled trial design, in which employees who have indicated their willingness to participate in a company smoking cessation programme will be randomly divided into two groups: an intervention group (140 participants) who are eligible for the programme and a control group (60 participants) who are not eligible.
The study schedule is based on an annual employee survey in September, followed by in-house recruitment of participants for the smoking cessation support programme. Among potential subjects, employees randomly assigned to the intervention group will be asked to participate in a six-month smoking cessation support programme. The smoking cessation programme provides information on the health hazards of smoking and passive smoking through pamphlets and videos, and fully subsidises the cost of outpatient smoking cessation visits, including a total of five standard smoking cessation treatments over a 12-week period, as well as the transportation costs for the visits (provided they are covered by health insurance, excluding online).
The costs of outpatient smoking cessation visits and transport costs will only be paid if the patient has undergone a total of five standard smoking cessation treatments over a 12-week period until the end of the visit, and will not be paid if the visit is interrupted.
Before and after the experiment, information on the individual's and family members' smoking frequency, a test to determine nicotine dependence (Tobacco Dependence Screener: TDS), and psychological characteristics and preference parameters such as time discount rate and risk aversion will be obtained through a questionnaire survey (answers in about 10-15 minutes).
Outcomes for measuring the effectiveness of smoking cessation include information on engagement and satisfaction with work and life workload and stress reactions at the workplace from the employee survey, and information on name, gender, educational background, age, tenure, position, job title, assignment history, attendance information (sick-leave days and overtime including working at late nights and on holidays), and employee ID from the personnel database. The two groups will be compared after the programme is completed, and a follow-up survey will be conducted for up to three years afterwards.
