The purpose of this study was to test the reliability and validity of a self efficacy scale which was revised for Korean adolescents. The self efficacy scale was based on 48 smoking situations, developed by Best and Hakstian (1978), and was revised according to situations which tempt Korean adolescents to smoke. The 18 situations which were believed to have true characteristics of a temptation to smoke for Korean adolescents. The psychometric evaluation was done on 281 high school adolescents. The result revealed a high internal consistency Alpha coefficient of .97, Principal Component Factor Analysis with a varimax rotation which resulted in 3 factors with more than 1.0 of eigen value. The three factors were 'negative feelings, interpersonal relationship', 'dependence ', and 'self image'. There was a significant positive correlation of r=.290 between this self efficacy scale and the scale of intention for smoking cessation, and a significant negative correlation of r=-.330 between number of cigarettes they smoked. The result indicated that the self efficacy scale measuring adolescents' degree of efficacy in a smoking tempted situation was reliable and valid. Further application of research in the various age and sex groups was recommended for a generalization of the scale.

PURPOSE: The purpose of this study was to identify the degree of attaining a smoking cessation goal when an agreement on means to achieve smoking cessation among male college student smokers was established. METHOD: This study was planned as a nonequivalent control group non-synchronized design and the sample was divided into an agreement group and a comparison group by convenience sampling in a college of G city. The data was analysed with SPSS Win10.0 using a Likelihood chi2-test, Odds ratio, Paired t-test and ANCOVA. RESULT: The theory that the degree of smoking cessation will be higher in the agreement group than the Comparison group was rejected (delta = 2.567, p = .055). The theory that nicotine dependency will be lower in the agreement group than the comparison group was supported (F = 3.965, p = .049); however, the theory that the number of cigarettes smoked per day will be lower in the agreement group than the comparison group was rejected (F = 1.342, p = .252). CONCLUSION: It has been shown that an agreement on means to achieve smoking cessation goals is a key factor to success in quitting smoking.

OBJECTIVETo estimate the mediating effect of smoking abstinence self-efficacy (SASE) on the association between awareness of smoking hazard and successful smoking cessation.

METHODSA community-based case-control study was conducted in 642 smokers who successfully stopped smoking, and 700 smokers who failed in smoking cessation were used as controls. The awareness of smoking hazard was evaluated by total score of 12 items. The SASE was assessed by using Smoking Abstinence Self-Efficacy (ASES-S). The total effect was classified as direct effect and indirect effect through logistic regression analysis based on the KHB method.

RESULTSAfter adjusting the potential confounders, including age, age of smoking initiation, occupation, educational level and marital status, the mediating effect of SASE accounted for 6.03% among the total effect of awareness of smoking hazard in those who successfully stopped smoking while the direct effect accounted for 93.97% among the total effect. In the three specific situation of SASE, the mediating effect of SASE accounted for 6.80% (positive/social situations), 3.08% (negative/affective situations) and 2.32% (habit/addictive situations) among the total effect, respectively.

CONCLUSIONSASE has part mediating effect to influence on the association between the awareness of smoking hazard and successful smoking cessation. Improving smokers' awareness of smoking hazard may not only promote successful smoking cessation directly, but also contribute to quit smoking through improving the score of SASE.

BACKGROUND: The level of urine cotinine is an indicator of tobacco smoke exposure. The purpose of this study is to investigate urine cotinine for the purpose of assessing the smoking status of Korean smokers and non-smokers exposed to tobacco smoke. METHODS: The subjects were identified from the 2007-2009 and the 2010 data sets of the Korea National Health and Nutrition Examination Survey (KNHANES). They were assigned as non-smokers, current smokers and ex-smokers. Non-smokers were also divided into three subset groups according to the duration of smoke exposure. Each group was stratified by gender prior to analysis. RESULTS: The median value of urine cotinine in the male current smokers was 1,221.93 ng/mL which was the highest among all groups. The difference between levels of urine cotinine for male and the female groups was statistically significant (p<0.01). In the female group, passive smoke exposure groups reported higher urine cotinine levels than non-exposure groups (p=0.01). The cutoff point for the discrimination of current smokers from non-smokers was 95.6 ng/mL in males and 96.8 ng/mL in females. The sensitivity and specificity were 95.2% and 97.1%, respectively, in males, 96.1% and 96.5% in females. However, the determination of urine cotinine level was not useful in distinguishing between passive smoke exposure groups and non-exposure groups. CONCLUSION: Urine cotinine concentration is a useful biomarker for discriminating non-smokers from current smokers. However, careful interpretation is necessary for assessing passive smoke exposure by urine cotinine concentration.

PURPOSE: This study examined the effectiveness of an Adolescent Motivational Interviewing Cessation program on smoking cessation change. The study was done with a nonequivalent control group pretest-posttest design. METHODS: The participants were 39 high school students from G city, who were in school from September 1 to October 30, 2009. The students were assigned to the experimental group (20) and participated in the motivational interviewing cessation program or to the control group (19) who did not participate. Data analyses involved chi2-test, independent t-test, Repeated Measures ANOVA, and utilized the SPSS program. RESULTS: The experimental group had significantly less daily smoking, nicotine dependence and smoking temptation in comparison to the control group. The experimental group had significantly higher stage of change in comparison to the control group. CONCLUSION: The results of the study indicate that a motivational interviewing cessation program delivered to adolescents who smoke is an effective method of encouraging cessation, and can be utilized as an effective nursing intervention for adolescents who smoke.

PURPOSE: The present study aimed at developing an integrative stage model of smoking cessation behavior by combining highly predictable constructs extracted from previously verified health behavior models. The fitness of the hypothetical model was also tested. METHODS: The study participants were 214 Chinese students studying in Korea, presenting high smoking rates. Perceived severity, benefit, barrier, self-efficacy, and social support were measured using the modified AttitudeseSocial InfluenceseSelf Efficacy Questionnaire. Demographic and smoking-related characteristics were also evaluated. RESULTS: Results showed that the hypothetical model provides a good fit. Significant psychosocial predictors of smoking cessation stage were perceived benefit (p = .050), barrier (p = .003), and social support (p = .003). Among demographic and smoking-related characteristics, gender (p = .030), duration of smoking (p = .010), and previous smoking cessation experience (p = .020) were found to influence smoking cessation stage. In addition, gender, age, number of cigarettes smoked, previous smoking cessation experience, smoking-related symptoms, and smoking cessation education needs were found to influence psychosocial constructs significantly. CONCLUSION: The significant psychosocial predictors and demographic and smoking-related characteristics defined in the present study appear to be potent and promising predictors of smoking cessation behavior stages for a cohort of Chinese students studying in Korea.

PURPOSE: This study was done to evaluate the predictive value of aspects of the Transtheoretical model (TTM) of behavior change as applied to smoking cessation in a rural population. METHOD: A convenience sample was recruited from a public health center in a community. A total of 484 participants were recruited, including 319 smokers, 116 ex-smokers and 49 non-smokers. A cross-sectional and descriptive design was used in this study. Data was analyzed using descriptive statistics, frequency statistics, ANOVA and Logistic regression. RESULT: The major findings were 1) The participants were assessed at baseline for their current Stage of Change resulting in a distribution with 42.1% in Precontemplation, 24.1% in Contemplation, 9.7% in Preparation, 6.2% in Active, and 17.9% in the Maintenance stage. 2) There were statistically significant differences of processes of change, decisional balance and situational temptation across the stages of change. 3) The main factors that affect smoking cessation were age, number of years smoking, age when began smoking, self-liberation and negative/affective situations, which combined explained 33.2% of the smoking cessation. CONCLUSION: TTM variables measured prior to a smoking cessation program added little predictive value for cessation outcome beyond that explained by demographic and smoking history variables.

PURPOSE: The purpose of this study was to identify the effects of a smoking cessation program on the amount of smoking and nicotine dependence and the self-efficacy of smoking cessation for smoking workers. METHODS: The total number of subjects was 38 smokers and was divided into two: 16 smokers were placed in the experimental group and 22 in the control group. A nonequivalent control group pretestposttest design was used. The smoking cessation program consisted of two sessions and was implemented for two hours daily for five days. Data was analyzed by using the SPSS/WIN 11.0 program with Chi2-test, t-test or Mann-Whitney U and ANCOVA. RESULTS: After the treatment, those belonging to the experimental group showed a significantly decreased amount of smoking, a decreased nicotine dependency and increased self-efficacy compared to the control group. CONCLUSION: The smoking cessation program was effective for diminishing the amount of smoking, decreasing nicotine dependence and improving self-efficacy. Therefore, this program is recommended as a smoking cessation strategy for adult smokers.

Nicotine, the primary psychoactive components of tobacco smoke, produce diverse neurophysiological and behavioral effects through several brain regions and neurochemical pathways. It acts as an agonist to activate and desensitize nicotinic acetylcholine receptors. Nicotinic signaling leads to activation of reward centers in the CNS, including the mesoaccumbens dopamine system, which ultimately leads to behavioral reinforcement and addiction. Indeed, the actions of nicotine on many systems, including brainstem cholinergic, GABAergic, glutaminergic, noradrenergic, and serotonergic systems, may help to mediate nicotine effects related to addiction. And many years of smoking induces neuroadaptations in acetylcholine and dopamine systems. Moreover, the long-term synaptic changes results in learned behaviors and memory which are associated with smoking. We reviewed the nicotinic synaptic mechanisms in midbrain dopaminergic areas. In summary, nicotine as obtained from tobacco interacts with multiple nicotinic acetylcholine receptor subtypes on dopamine, GABA, glutaminergic neuron to produce not only the acute positive reinforcement but also the synaptic changes associated with learning and memory.

OBJECTIVETo reduce tobacco consumption and exposure to passive smoking in China.

METHODSDiscussion consisting of 80 focus groups and 35 interviews were held in three rural intervention counties of Jiangxi, Henan, and Sichuan Provinces. Participants came from hospitals, schools, rural areas, and urban areas.

RESULTSTobacco use and exposure to passive smoking were widely prevalent in the investigated schools, hospitals, county towns, and rural areas. Knowledge of the risks for passive smoking on health is lacking, especially in rural areas. Barriers to the control of tobacco use in public places include reluctance of administrators to implement tobacco control policies, lack of consistent policies, difficulties with regulations and enforcement, and reluctance of non-smokers to exercise their right to clean air.

CONCLUSIONTo curb the current tobacco epidemic in China, tobacco control efforts must focus on reducing exposure to passive smoking. A strategy should be formulated to reduce the factors that contribute to tobacco use and exposure to passive smoking.
