The purpose of this study was to investigate sodium consumption and related psychosocial factors among hypertensive patients and normal adults through questionnaire development. The Theory of Planned Behavior provided the basis for the study. The mean blood pressure of subjects was 117. 1 mmHg/78.55mgHg in normal adults(N-218), 159.65mmHg/102.05mmHg(systolic/diastolic) in hypertensive group(N=219) and the sodium consumption was 5219.4${\pm}$1821.3mg in normal adults and 4631.4${\pm}$1749.1mg in hypertensive group. The results of Multiple logistic regression analysis showed that the odds of being hypetensive group were increasd as subjects felt that dalty food (OR=1.5) (OR=0.8). The odds of beign hypertensive group increased as subject received more support. With respect to perceived control, the odds of being hypertensive group were increased as subjects felt more confident in contolling salty intake when spouse likes to take salty food(OR=1.4). In contrast, subjects felt less confident in contolling sodium consumption when they took medicine(OR=0.8). Study findings revealed that all three factors, attitudes, subjective norms, and perceived control contributed to the model for explaining intentions, with subjective norms being most important. This findings provided the empirical evidence for the TPB in explaining salt intake. This study suggest that educational interventions for hypertension patients focus on changing sodium consumption through changing attitude toward high sodium consumption, subjective norms, perceived control over reducing sodium consumption of specific situations, specially subjective norms and perceived control. In addition, interventions may include strategies to change attitudes toward sodium consumption by helping hypertensive patients realize negative beliefs and modifying positive beliefs and to elicit and maintain subjective norm from doctors, family and neighbors, and to increase control beliefs for reducing sodium consumption.(Korean J Nutrition 33(8) : 833-839, 2000)

The purpose of this study was to determine the factors related to eating breakfast for middle and high school students in Seoul using the Theory of Planned Behavior. Out of 2,280 questionnaires distributed to 22 schools, 2,060 were returned (90.4% response rate) and 1,899 were analyzed (83.3% analysis rate). Gender, self-perceived household income level and mother's working status were examined as demographic factors. "Attitude", "Subjective norm", "Perceived difficulty in access to breakfast", "Perceived time restriction" and "Self restriction to breakfast" were extracted as psychosocial factors as the results of factor analysis and reliability test using 17 items. In case of middle school students, boys were more likely to skip breakfast than girls. The students perceiving their household income level "low or middle low" were more likely to skip breakfast than those who perceived their household income level "high or middle high". The students whose mother had a job tended to skip breakfast than those whose mother had no job. In case of high school students, the students perceiving their household income level "low or middle low" tended to skip breakfast than those perceiving their household income level "high or middle high". The results of analysis of variance, all the psychosocial factors examined in this study-"Attitude", "Subjective norm", "Perceived difficulty in access to breakfast", "Perceived time restriction" and "Self restriction to breakfast"- were related to the frequencies of eating breakfast during weekdays in both the middle and high school students.

Purpose: The purpose of this study was to explore the intentions and influencing factors of intentions to care for New Influenza A ($H_1N_1$) patient Methods: This study involved a descriptive design using self-administered questionnaire. Intentions to care for H1N1 patient was evaluated by prediction tool, based on the Theory of Planned Behavior (TPB). The data were analyzed by SPSS 17.0 using descriptive statistics, t-test, ANOVA with a Scheffe test, Pearson's correlation and multiple regression analysis. Results: The level of intention was high, attitude was negative, subjective norm was high, and perceived behavioral control was moderate. The general regression model with intention as a dependent variable was statistically significant (F=39.31, p<.001). 28.1% of variance in intention was explained by subjective norm (t=8.75, p<.001), and perceived behavioral control (t=4.28, p<.001). Among the predictors, subjective norm had the greatest effect on intention (${\beta}=.44$). The nurse with the higher subjective norm and more positive perceived behavioral control reported the higher intention. Conclusion: The findings of this study suggested that the various aspects of nurse's characteristics should be considered when establishing strategies to improve the nurse's intention for care of infectious disease.

The purpose of this study was to understand the structures underlying Korean elementary teachers' attitudinal beliefs toward reform-oriented mathematics instruction and predict their intentions to change traditionally-oriented teaching practice. The theory of planned behavior (TPB) developed by Fishbein and Ajzen provided a conceptual framework for the examination of factors that influence Korean teachers' beliefs, attitudes, subjective norms and perceptions of control factors. Data were gathered through a survey instrument from 281 teachers who teach mathematics in a metropolitan city of Korea. Descriptive statistics and multiple regression analyses were conducted to analyze the data. Findings indicate that Korean elementary teachers' change in Instructional practice is based primarily on their judgements regarding the likelihood of occurrences of certain consequences if they engage in teaching mathematics in a reform-oriented way. Teachers' perceptions of important others regarding the reform-oriented mathematics instruction seem to play a minor role in teachers' instructional change. Teachers' perceptions about control factors that prohibit or help teach mathematics in a reform-oriented way do not seem to make significant improvement in predicting their intentions to change traditionally-oriented teaching practice.

The main objective of this paper is to examine the applicability of Linan and Chen's entrepreneurial intention model (EIM) in predicting the entrepreneurial intention. EIM is an adaptation of the Theory of Planned Behavior that focuses on entrepreneurial intention and hypothesizing slightly different patterns of relationship with regards to subjective norms. The model also includes human capital and demographic factors. Snowball sampling method was used to collect data using the entrepreneurial intention questionnaire (EIQ) through several social media platforms. The survey indicates that the overall entrepreneurial intention of Saudi students is high (mean = 5.41). Eight out of the seventeen hypothesized relationships were found to be significant. Among the demographic variables, gender-personal attitude was significant whereas self employment experience and years of business education were found to be significantly related with perceived behavioral control. The statistical analysis using partial least square structural equation modelling validated the model. All the three antecedents of entrepreneurial intention were significantly related with entrepreneurial intention. The results of this study will help policy makers to get deep understanding into the phenomenon of entrepreneurship among Saudi university students and thereby develop a conducive environment. This study also validates the entrepreneurial intention model in a different cultural context.

Financial preparation for retirement means making financial plans by predicting expected incomes and expenditures needed for maintaining success in later life. Because this preparation needs long-term planning, preparing as early as possible is recommended. This study, therefore, uses theory of planned behavior for examining the intention of financial preparation for retirement of consumers in their 20s and 30s. By using financial education and its understanding as additional variables, this study also intends to examine the ultimate effects on the intention. The following is a summary of the main results and suggestions. First, the level of consumer financial education is lower than the average. The level of understanding finance is lower than the average, and particularly, the level of understanding retirement related finance is much lower. Second, the more the attitude of financial preparation for retirement is positive, and the higher the level of subjective norm or perceived behavioral control is, the level of the intention of financial preparation for retirement tends to be more higher. Therefore, relevant efforts to encourage this preparation are needed. Third, the level of the intention of financial preparation for retirement is higher than the average, whereas financial education has no effects on the intention. This means that despite the importance of the financial education, its current implementation has many problems. The suggestions of this study are as follows. First of all, this study can provide preliminary data for developing retirement planning programs. In addition, in terms of the policy, given that this study targets relatively young consumers in their 20s and 30s, it can provide preliminary data for making policies for their future retirements.

The study purpose was to investigate psychosocial factors related to smoking among adolescent boys. The Theory of Planned Behavior provide the basis for the study. Twenty-five attitudinal beliefs, 9 normative beliefs and 20control beliefs were identified through questionnaire development. The data were analyzed using t-test and χ2-test. Thirty-three percent of 300 students were smokers. Most of the beliefs examined were significantly different between smokers(n=92) and nonsmokers(n=92). With respect to attitudinal beliefs, smokers responded less negatively on the items of bad health effects of smoking such as sore throat, headache, chest pain, risk of cancer and bad blood circulation(p<0.001), and decreased physical strength(p<0.05). Smokers believed less negatively on the items that smoking leads to bothering others, bad breath, yellow teeth and making them spend money(p<0.001). In contrast, smokers felt more positively on smoking as a means of stress management, relaxing, helping digestion(P<0.001). Smokers felt less pressure for not smoking from significant others. Especially mother, siblings, friends, girl friends, seniors of school were important sources of influence regarding subject's smoking. Smokers felt less confident in controlling the urge to smoke in several situations including; when they were with friends or asked to smoke by friends; after the meal, or drinking; when they were bored or stressed, upset, and when they felt unstable(p<0.001). Smokers also scored lower on specific skills to quit or control the urge to smoke as well as overall perceived control, compared to nonsmokers(p<0.001). These results suggest that interventions for adolescents incorporate diverse strategies to increase the perceived control over smoking in specific situations as well as overall perceived control, to help them realize and modify attitudinal beliefs, and to elicit support from significant others for not smoking.

Purpose: This study was performed to examine motivational factors affecting sweetness preference in Korean and Japanese children. We identified meaningful variables that could be targeted to nutrition education interventions designed to overcome innate barriers and reduce sweetness preference and sweet food intake in Korean and Japanese children. Methods: Questionnaire surveys and sweetness preference test were conducted to examine variables affecting behavioral intention (BI) regarding sweetness preference. Questionnaire variables were based on the theory of planned behavior. Participants were recruited from one urban school from each country. In total, 166 children (mean age: 8.4 years) and their guardians (n = 166) participated in the study. A trained research assistant provided all children with personal guidance regarding completion of the sweetness preference test and survey questionnaire at school. The data were analyzed using Pearson's correlation coefficients, t tests, repeated measure ANOVA, and stepwise multiple regression analysis (significance level: p < 0.05). Results: Perceived behavioral control (PBC) and parenting practice were significantly associated with BI in both groups. Motivation to comply affected BI only in Japanese children, whereas affective attitude was associated with BI only in Korean children. In predicting sweetness preference, BI was associated only in Japanese children, whereas sweets consumption frequency had a significant effect in Korean children. Conclusion: The study shows similarities and differences in motivational factors, which could be considered when developing nutrition education programs in Korea and Japan. PBC and parenting practice were common factors in predicting BI. In predicting sweetness preference, BI had a significant effect on Japanese children, whereas sweets consumption frequency was the greatest contributor in Korean children.

This study was done to compare nutrient intakes, anthropometric indices, and psychosocial factors related to smoking by smoking status among adolescent girls in Seoul. Subjects were high school students, and smokers were 17.6%. Nutrient intakes were analyzed by convenient method, and anthropometric measurements were done by Inbody 2.0. Psychosocial factors of smoking were examined based on the Theory of Planned Behavior : 26 attitudinal, 9 normative, and 17 control beliefs were used. Smokers smoked 5-7 cigarettes a day on average, with 1.26 pack-years of smoking, There were no significant differences in anthropometric characteristics, except fat distribution, between smoking(n=92) and nonsmoking(n=92) and nonsmoking(n=94) group. The percentage of alcohol groups. Especially, caloric intake (63.6% of RDA) were much below the recommended level. With respect to psychosocial factors, 18 out of 26 attitudinal beliefs were significantly different between smokers and nonsmokers. Smokers responded less negatively on the items of bad health effects of relax(p<0.001). In addition, smokers were more convinced of advantages of smoking (test, etc.)but responded less negatively on the disadvantages of smoking(bothering others, yellow teeth, bad breath, etc.). Smokers expressed less pressure for not smoking from siblings, friends, school seniors than nonsmokers. In addition, smokers, expressed less confidence in controlling the urge to smoker or quitting smoking in several situations, such as 'after a meal', 'feel bored', 'with friends', 'when angry' offered a cigarette by friends', 'drinking coffee or tea', 'drinking alcohol', 'seeing others smoke'(p<0.001). Smokers also felt less developing in applying specific skills for controlling the urge to smoker or quitting smoking. These findings suggest the need for developing smoking cessation programs for adolescent females, focusing on specific beliefs identified in this study.
