Background: Quit-Calendar has been developed and initially tested in Phase I for the Quit-For-King project. The effectiveness and satisfaction of its properties were later investigated among village health volunteers.

Objective: To investigate the Quit-Calendar effectiveness, factors related to quit success, and its satisfaction under the ‘Quit-For-King’ Project.

Materials and Methods: One hundred eleven current smokers underwent the program. Each participant needed to go ‘cold turkey’ technique, which mean to stop smoking at once, then received 5A counseling and a Quit-Calendar. The measuring parameters included continuous abstinence rate (CAR) and point prevalence abstinence rate (PAR), investigated at 2-weeks, 1-, 3-, and 6- month periods via statistical analysis.

Results: Most of the participants were males (96.4%), smoked 10 cigarettes per day (53%), heavy smokers. They were mostly in ‘preparation stage’ of change (49%). CAR was 26.11% and PAR values increased by the end of the 6-month. There were statistically significant differences between the numbers of quitters using Quit-Calendar (p<0.001). Only three factors, including numbers of cigarettes, minor illness, and levels of readiness to quit significantly affected quit success (p<0.001). The smokers stated that the Quit-Calendar could possibly help them to quit smoking. Nonetheless, some limitations need to be resolved.

Conclusion: Quit-For-King project has been successful over a 3-year period. The Quit-Calendar is one of the cessation aids that promote quit success and help quitters to overcome nicotine withdrawal.
