Purpose This study examined the moderating and mediating effects of self-efficacy on the relationships between predictor variables (decisional balance and processes of change) and the outcome variable(stages of change) using the Transtheoretical Model. Design Cross-sectional data were collected from 147 current and former smokers at three vocational technical high schools in Korean metropolitan areas. Methods The survey instruments included decisional balance, self-efficacy, processes of change (behavioral and experiential), and stages of change. Regression analyses were used to identify the mediating effects of self-efficacy. Results Self-efficacy mediated the relationships of decisional balance and behavioral processes with stages of change, but not that of experiential processes with stages of change. Conclusions The study results will provide valuable information regarding how each predictor variable is connected and path through adoption of smoking cessation behavior. By understanding mechanisms of behavior change, health professionals could develop effective smoking cessation interventions with consideration of roles of self-efficacy in the smoking cessation behavior change.

Purpose: The purpose was to evaluate the effects of a transtheoretical model (TTM) based exercise counseling offered with music skipping rope exercise on components of the TTM (stages of change, decisional balance, and self-efficacy), body mass index, glucose, and lipid profile of overweight/obese children in Korea. Methods: This study used a nonequivalent pretest and posttest experimental study design. A total of 75 overweight/obese children participated in the study. Eight sessions of exercise counseling combined with music skipping rope exercise for 12 weeks were offered for children in the experimental group, while one session of exercise counseling with music skipping rope exercise for 12 weeks was offered for children in the control group. Outcomes were measured at baseline, and 6 months after the intervention. Results: After the intervention, self-efficacy significantly improved among children in the experimental group (p = .049), while these children maintained their baseline BMI at 6-month follow-up (p > .05). Among children in the control group, BMI significantly increased (p < .05). Fasting blood sugar significantly increased for both groups after the intervention (p < .05). However, a greater increase was observed for the control group. Conclusions: Our study partially supports the hypothesis that a TTM-based exercise intervention is effective in maintaining BMI and improving self-efficacy of overweight/obese children. The TTM-based counseling combined with exercise classes has potential to control weight among overweight/obese children, while involvement of parents and children in the development of the theory-based intervention may generate further benefits regarding health and well-being of overweight/obese children.

Purpose: This purpose of this study was to examine the differences of BSE(Breast-Self Examination) performance and health beliefs between single and married women who lived in Busan Metropolitan area and to identify which factors influence the BSE. Method: The study subjects were recruited from both single(N=178) and married (N=143) women. Data were collected using structured self-administered questionnaires and the subjects were also asked whether or not they did a BSE in the last year? Data were analyzed by descriptive statistics, t-test, x2-test and logistic regression analysis. Result: The married women who performed the BSE was statistically higher than that of single women. Regarding to the BSE-related health belief the score of seriousness and motivation was significantly higher in married women. The score of barriers was significantly higher in single women. Significant influencing factors on BSE performance were 'Seriousness', 'barriers' and 'benefits' and those variables explained 18.8% of variance in performance of BSE. Conclusion: There was a differences in BSE-related health belief and performance between single and married women. Among health belief variables, seriousness, barriers and benefits were core variables predicting the BSE performance of single and married women together. 본 연구는 일 지역에 거주하는 20-39세 미혼여성과 기혼여성의 유방자가검진 수행정도, 유방암에 대한 지식과 건강신념을 비교하고, 유방자가검진수행에 영향을 미치는 예측변인을 확인하는 횡단적 조사연구(cross-sectional survey design)이다. 연구결과 기혼여성의 유방자가검진수행 정도가 미혼여성에 비하여 통계적으로 높게 나타났으며, 유방암 지식은 통계적으로 차이가 없었다. 또한 건강신념에 있어서는 유방자가검진에 대한 심각성과 건강관심도가 미혼여성에 비하여 기혼여성에서 통계적으로 유의하게 높았고, 장애성은 통계적으로 낮게 나타났다. 유방자가검진 수행에 영향을 미치는 예측요인으로는 심각성, 장애성, 유익성이 통계적으로 유의한 영향을 미치는 변인으로 나타났다.
