The purpose of this study was to examine the effectiveness of a smoking cessation healing camp for male workers. A single group pre-test post-test design was used. An experimental group (n=28) allocated into a smoking cessation healing camp which was provided for two days and one night. Effectiveness of the intervention was measured at soon after smoking cessation healing camp. There were significant differences between pre-test and post-test on readiness to quit smoking(t=-2.64, p=.013), smoking cessation self-efficacy(t=2.42, pp=.022), nicotine dependence(t=2.55, p=.017), and depression(t=2.85, p=.008). In conclusion, the smoking cessation healing camp is effective for male smokers in workplace settings by providing insightful antismoking information and encouraging smoking cessation self-efficacy and readiness to quit smoking.
