Study Summary

Indonesia is one of the countries that does not sign The World Health Organization Framework Convention on Tobacco Control (WHO-FCTC), and the numbers of Indonesian smokers increase every year. The Volitional-Help Sheet (VHS) has been used successfully to help people quit smoking, but has not yet been tested in Indonesia. The present study aims to adapt and implement the VHS to promote smoking cessation among smokers aged 20- 45 years. The main outcome measure is smoking abstinence; secondary outcomes are nicotine dependence, and capabilities, opportunities and motivations.

Study Description

The main outcome measure is smoking abstinence; secondary outcomes are nicotine dependence, and capabilities, opportunities and motivations. All participants will be smokers aged 20-45 years who will complete self-report measures of outcomes over three waves of data collection. Once baseline measures are collected, participants will be randomised at wave 1 to intervention versus control condition. Participants in the intervention group will complete the VHS for smoking cessation in addition to the baseline measures. At wave 2, one-month following wave 1, participants will again be randomised to intervention (complete the VHS) and control condition. There will thus be four conditions: control, early intervention, late intervention and repeated intervention. Outcomes will be assessed at wave 3, six-months after wave 2.
