OBJECTIVES: This study was conducted to perform an effect size analysis of psychosocial interventions for internet addiction and to identify the intervention moderators applied to school-aged children. METHODS: For the meta-analysis, studies were included that were published in English or Korean until January 2015, without limitation in terms of the year. They were retrieved from 11 electronic databases and by manual searches according to predefined inclusion criteria. RESULTS: A total of 37 studies were selected, which included 11 treatment conditions and covered a total of 1,490 participants. The effect size estimates showed that psychosocial interventions had a large effect for reducing internet addiction (standardized mean difference [SMD], -1.19; 95% confidence interval [CI], -1.52 to -0.87) and improving self-control (SMD, 0.29; 95% CI, 0.11 to 0.47) and self-esteem (mean difference, 3.58; 95% CI, 2.03 to 5.12). The moderator analyses reveals that group treatments, a selective approach, a long duration, a community setting, or higher school grade had a larger effect. CONCLUSIONS: The findings of this review suggest that psychosocial intervention may be used to prevent Internet addiction in school-aged children, although further research should be conducted using a randomized controlled trial design or diverse age groups to provide evidence-based recommendations.

The purpose of this study was to test the Theory of planned Behavior in the prediction of contraceptive behavior among married women. This study used a descriptive correlational design to examine the relationships among the study variables. Eighty married women in Seoul and Kyungki-do participated in this study. Research instruments used were the tool for measuring TPB variables search as attitude toward contraception , subjective norm, perceived behavior control, and intention: and the tool for measuring contraceptive behavior . The former was modified by the researcher according to Ajzen and Fishbein(1980)'s guidelines for tool development and Jee(1993)'s tool. The latter was developed by the research. Data was collected from July 20, 1996 to October 25, 1996. The results are as follows: The three factors, attitude, subjective norm and perceived behavioral control of contraception can explain 30% of the variance in contraceptive intention. Inspection of path coefficient for each of the three predictor variables revealed that subjective norm and perceived behavior control were the predictor variables on intention, while attitude was not ; and intention and perceived behavior control factors can explain 42% of the variance in contraceptive behavior. Inspection of path coefficient for each of the two predictor variables revealed that intention and perceived behavior control were the predictor variables on behavior. In conclusion, this study identified that Theory of Planned Behavior was a useful model in the prediction of contraceptive behavior, and the contraceptive service program based on the TPB variables would be an effective nursing intervention for the change in contraceptive behavior.

PURPOSE: This study was conducted to identify factors affecting health promotion behaviors of upper grade elementary students. METHODS: A descriptive study was carried out with 282 fifth or sixth elementary school students from two cities, Korea. Data were collected using self-administrative questionnaires containing items on health knowledge, attitudes, subjective norms, perceived behavior control and health promotion behavior, and analyzed using descriptive statistics, t-test, ANOVA, Cronbach's α, Pearson Correlation Coefficients, and multiple regression analysis with the SPSS/WIN 21.0 program. RESULTS: There were significant positive correlations between health promotion behavior and health knowledge (r=.36, p<.001), attitudes (r=.41, p<.001), subjective norms (r=.36, p<.001), perceived behavior control (r=.49, p<.001). Perceived behavior control (β=.38, p<.001), health knowledge (β=.26, p<.001), perceived health status - good (β=.15, p=.005) were significant factors affecting health promotion behavior and explained 31%(F=43.29, p<.001) of variance. CONCLUSION: Results indicate that level of health promotion behavior is appropriate and perceived behavior control is the most important factor for health promotion behavior among the predictors. These findings also suggest that it is necessary to promote perceived behavior control and health knowledge in developing health promotion intervention programs for these students, as well as a need to strengthen education on sex behavior and health, accident prevention and first aid.

PURPOSE: The purpose of this study was to define and clarify the concept of volition for health behavior. METHODS: For this study the process of Walker & Avant’s concept analysis was used. Seventeen studies from electronic data basses met criteria for selection. RESULTS: Volition can be defined by the following attributes: 1) planning, 2) maintenance of self-efficacy, and 3) self regulation. The antecedents of volition consisted of: 1) risk awareness, 2) outcome expectation, 3) perceived self-efficacy, and 4) social support. The consequences occurring as a result of volition were: 1) prevention of disability and complications, 2) improvement of functional ability, and 3) enhencement of quailty of life. CONCLUSION: Definition and attributes of volition identified by this results can be applied to develop measurements and intervention programs for chronic patients health behavior.

PURPOSE: The purpose of this study was to analyze the effects of academic stress among middle school students to their smartphone addiction while exploring the moderating effect of self-esteem and self-control in the relationship between academic stress and smartphone addiction. METHODS: A descriptive research design was used. The participants were 398 middle school students from one middle school in Seoul. A self-administered questionnaire was used to measure academic stress, self-esteem, self-control, and smartphone addiction. Data were analyzed with the SPSS/WIN 21.0 program. RESULTS: Smartphone addiction significantly differed according to gender, duration of smartphone use and average monthly amount of use. The hierarchical regression analyses revealed significant positive relations between academic stress and smartphone addiction. On the other hand, self-esteem and self-control were negatively related to smartphone addiction. Self-control appeared to have moderating effects in the relationship between academic stress and smartphone addiction. CONCLUSION: It is important when developing smartphone addiction prevention programs to consider self-control that showed moderating effects.

PURPOSE: This study aimed to examine the effects of an adolescent obesity management educational program (AOMEP) on middle and high school teachers. METHODS: A quasiexperimental, pretest post-test design was performed to test primary variables, including adolescent obesity management knowledge, attitudes, perceived behavioral control, and behavioral intention based on the concepts presented in the Theory of Planned Behavior. RESULTS: A total of 61 teachers participated. The experimental group (n = 30) received 15 hours of AOMEP, whereas the control group (n = 31) did not receive any. The experimental group showed significant improvement in knowledge (t = 2.53, d = .65, p = .014) and attitude (t = 2.77, d = .71, p = .008) toward adolescent obesity management compared to the control group. However, there were no significant differences in perceived behavioral control or behavioral intention between the groups. CONCLUSIONS: AOMEP may be utilized as an effective obesity management program for adolescent students in schools.

PURPOSE: The purpose of this study was to identify effects of attitude, subjective norm, and perceived behavior control toward Human Papillomavirus (HPV) on HPV vaccination intention in female high school students. METHODS: Subjects of this study were female students aged 16 to 17 years, the optimal age group of HPV vaccination, arbitrarily selected from three high schools in B city. A total of 140 students agreed to participate in this study. Data were analyzed using descriptive statistics, t-test, ANOVA, correlation, and stepwise multiple regression. RESULTS: Attitude, subjective norm, and perceived behavior control toward HPV were factors influencing HPV vaccination intention of subjects. Perceived behavior control toward HPV vaccination was the most influential factor. These factors accounted for 49% of HPV vaccination intention. CONCLUSION: These results suggest a need to increase perceived behavior control to increase HPV vaccination intention. The government needs to establish a national policy system such as financial support for HPV vaccines and free vaccinations so that students are aware that HPV vaccines can be easily inoculated.

PURPOSE: To investigate factors that affect behaviors of reducing exposure to endocrine disrupting chemicals (EDCs) in breastfeeding mothers. METHODS: Subjects were 166 breastfeeding mothers who were recruited from January 25 to April 15, 2018. The questionnaire consisted of items associated with behaviors of reducing exposure to EDCs, attitude to behaviors of reducing exposure, subject norms of behavior of reducing exposure, and perceived behavior control. Data were analyzed by t-test, ANOVA, Pearson correlations, and stepwise multiple regression. RESULTS: Factors influencing behaviors of reducing the exposure to EDCs were attitude toward behaviors of reducing exposure, perceived barrier, and period of lactation. The more positive the attitude toward behaviors of reducing exposure was, the lower the perceived barrier. The longer the feeding period, the higher the behaviors of reducing the exposure to EDCs. CONCLUSION: To enhance behaviors of reducing the exposure to EDCs, it is necessary to develop a positive educational program in breastfeeding department to improve attitude toward behaviors of reducing the exposure to EDCs, decrease perceived barrier, and increase the breastfeeding period.

PURPOSE: This study was carried out to find factors affecting weight-control behavior intention in female college students based on the theory of planned behavior. METHODS: The subjects were 453 female students from everywhere other than the Gangwon Province and Jeju Island. Data were collected by using a questionnaire. RESULTS: The factors affecting weight-control behavior intention in female college students within 2 weeks were attitudes and subjective norms. These two factors accounted for 20.0% of weight-control behavior intention. Also, when body shape satisfaction and BMI were added to variables of the theory of planned behavior like attitudes, subjective norms, and perceived behavior control, these 5 factors accounted for a total of 34.1%. CONCLUSION: Due to their distorted perception in preferring skinny body shapes, female college students are likely to attempt at inappropriate weight control behavior. Through intervention with such factors as attitudes and body image satisfaction, which have been derived from the results of this study, healthy weight control behavior should be pursued in practice.
