Abstract Background Polycystic ovary syndrome is the most common endocrine disorder among adolescents and adults. Given the importance of healthy nutritional behaviors in management of this disease, the present study was conducted to determine the impact of an educational intervention program based on the theory of planned behavior on the nutritional behaviors of adolescents and young adults with polycystic ovary syndrome. Methods In this field trial study, 72 participants aged between 15 and 21 years old from four gynecology clinics in Shiraz, Iran, were assigned into the intervention and control groups. Educational intervention program was implemented based on the theory of planned behavior over 4 sessions during two weeks. The data collection tools were researcher-made questionnaires of demographic information, knowledge assessment, and assessment of theory of planned behavior constructs, as well as a questionnaire for assessing consumption of food groups, fast food, and snacks. The data were collected at two stages (once at baseline and once three months after the intervention), and then the changes in knowledge, attitude, subjective norms, the perceived behavioral control, behavioral intention, and nutritional behavior were analyzed using descriptive and inferential statistical methods (t-test, Chi-square, Mann- Whitney U, and Wilcoxon tests; as well as one- way ANOVA, repeated measures ANOVA, and ANCOVA, respectively). Results Statistically significant increases were observed in the mean scores of knowledge, attitude, subjective norms, the perceived behavioral control, behavioral intention, and nutritional behavior in the intervention group by passing three months from the intervention compared to the scores before the intervention (P < 0.001). However, these differences were not statistically significant in the control group (P > 0.05). Moreover, the mean scores of knowledge, attitude, subjective norms, perceived behavioral control, behavioral intention, and nutritional behavior had no statistically significant difference before the intervention between the two groups; however, this was statistically significant by passing three months from the intervention (P < 0.001). Conclusion Considering the effect of an educational intervention program based on the theory of planned behavior on creating healthy nutritional behaviors in adolescents and young adults with polycystic ovary syndrome, it is recommended to use it in order to improve the nutritional health of them.

Purpose This paper aims to examine travelers` behavioral intention of traveling in the period of coronavirus by employing the theory of planned behavior. The framework incorporates attitude, subjective norms, perceived behavioral control and a very crucial construct, i.e. perceived risk, as per the current critical scenario of COVID-19. Design/methodology/approach Data was collected using a survey instrument on the internet by posting the questionnaire link over social network web pages of online traveling websites. The data was analyzed using structural equations modeling with AMOS 22.0 and SPSS software, and the proposed hypotheses were statistically tested. The sample under consideration constitutes 417 responses. Findings Empirical findings suggest that attitude, perceived behavioral control and perceived risk are significant for predicting behavioral intention while subjective norms do not. And these variables explained about 35 percent of the variance in behavioral intention of traveling in the period of coronavirus. Research limitations/implications This study can benefit travelers, tourism and hospitality industry, governments, aviation industry and other relevant organizations as this paper offers the latest updates and essential information regarding traveler`s intention of traveling in the period of coronavirus. The study mainly focuses on India, so the generalizations of results to other countries are unwanted. Originality/value The primary value of this paper is that it tested the theory of planned behavior by incorporating perceived risk in the context of COVID-19. To the best of authors’ knowledge, in Indian context, there is no study which has tested the TPB by adding perceived risk in explaining the Indian citizens’ behavioral intention of traveling in the period of Coronavirus.

Moderating Role

This study extends the theory of planned behavior by taking communication factors into account to examine the determinants of pro-environmental behavioral intention in haze mitigation. Unlike other theory of planned behavior (TPB) extension studies, we shift the focus of inquiry from examining the mediating role of TPB variables to investigating the moderating role in promoting pro-environmental behavior. Using an online survey in China, the results indicated that attitude, subjective norms, perceived behavioral control, and attention to haze-related efficacy messages were positively associated with pro-environmental behavioral intention. Notably, attention to haze-related threat messages had no significant relationship with behavioral intention. Moreover, moderation analyses revealed that the interaction effects between attention to efficacy messages and attention to threat messages on behavioral intention vary among people with different attitude, subjective norms, and perceived behavioral control. Theoretically, this study contributes to the literature of the TPB by analyzing its moderating role in promoting behavior change. Findings from this study suggest the importance of disseminating distinctive media messages to audiences with different personality traits, which is beneficial for practitioners to tailor specific messages in environmental campaigns.

Aging Well

The predictive value of the Theory of Planned Behavior (TPB) on intention and physical activity (PA) over time was examined. Data from the Aging Well and Healthily intervention program (targeting perceived behavioral control and attitude, not subjective norm) were analyzed, including pretest (T0), posttest (T1, except subjective norm) and 4–6 months follow-up (T2, PA outcomes only) (N = 387, M age 72 years). Structural equation modeling was used to test a TPB model. PA was measured subjectively using the Voorrips sports subscale (T0 and T2), items measured perceived increase in PA (T1), and adherence to exercises (T1 and T2). Model fit was good. The TPB explained variation in intention well (R2 .54–.60) and some PA behavior (R2 .13–.16). The intervention successfully got participants to exercise independent of the measured TPB concepts. More TPB studies in the context of interventions are needed.

Introduction: Overweight adolescents have been reported to struggle in losing weight. However, their intention to engage in weight loss practice remains unclear. Therefore, the aim of this qualitative study was to understand the factors that lead to the intention of weight loss practice among overweight adolescents using the Theory of Planned Behavior (TPB). Methods: Thirty-three overweight adolescents aged between 13 to 17 years old were recruited from three secondary schools in Selangor. They responded to a semistructured interview based on TPB that has three core antecedents; i) Attitude toward the behavior, ii) Subjective norm, and iii) Perceived behavioral control. Results: There is a high possibility that overweight adolescents will perform weight loss practice if the diet plans they followed, or physical activity they performed, or slimming product they consumed prove to make them lose some kilograms (Attitude). Besides that, the social pressure received from social interactions with parents and peers in a form of weightrelated criticisms and weight-related teasing may encourage overweight adolescents to be thin and reducing weight (Subjective norm). Finally, the emergence of intention that subsequently lead to weight loss practice is either driven by social interactions and media influences, or limited by some of the identified barriers (Perceived behavior control). Conclusions: The TPB is suggested to be an effective framework to understand the intention of weight loss practice among overweight adolescents, allowing for the development of obesity intervention program.

Patient safety is an important healthcare issue worldwide, and patient accidents in the operating room can lead to serious problems. Accordingly, we investigated the explanatory ability of a modified theory of planned behavior to improve patient safety activities in the operating room. Questionnaires were distributed to perioperative nurses working in 12 large hospitals in Korea. The modified theory of planned behavior data from a total of 330 nurses were analyzed. The conceptual model was based on the theory of planned behavior data, with two additional organizational factors—job factors and safety management system. Individual factors included attitude, subjective norms, perceived behavioral control, behavioral intention, and patient safety management activities. Results indicated that job factors were negatively associated with perceived behavioral control. The patient safety management system was positively associated with attitude, subjective norm, and perceived behavioral control. Attitude, subjective norm, and perceived behavioral control were positively associated with behavioral intention. Behavioral intention was positively associated with patient safety management activities. The modified theory of planned behavior effectively explained patient safety management activities in the operating room. Both organizations and individuals are required to improve patient safety management activities.

Abstract Background The prevalence of chronic diseases is increasing worldwide. Implementing educational programs is an important step in prevention of chronic diseases in the community setting. This study was conducted to assess the effect of educational program based on the Theory of Planned Behavior (TPB) on the osteoporosis preventive behaviors in middle-aged individuals. Methods A randomized clinical trial was conducted on 64 middle-aged individuals presenting to primary care centers. A researcher-made questionnaire developed according to “a guide for compiling and analyzing the questionnaire based on TPB” was used for data collection. Random block sampling was applied to assign participants to control and intervention groups after ensuring the validity and reliability. An educational program on osteoporosis prevention was conducted in six educational sessions based on the TPB constructs for the intervention group in primary care centers. Control group received routine education about lifestyle changes including osteoporosis by primary care centers. Eight weeks after the intervention, the questionnaires were completed again and the data were analyzed using the SPSS V16 software. Results Independent t-test found no significant difference in the mean score of knowledge, osteoporosis preventive behavior, attitude, subjective norms, perceived behavioral control and behavioral intention between intervention and control groups before intervention (p > 0.05). After the intervention, however, a significant difference was found in the mean score of knowledge, attitude, subjective norms, perceived behavioral control and behavioral intention between the cases in intervention and control groups (P < 0.05). In addition, based on repeated measurement ANOVA, the intervention had a significant effect on knowledge, preventive behaviors, attitude, subjective norms, perceived behavioral control, and behavioral intention (P < 0.05). Conclusions The results of the present study showed that implementation of an educational intervention based on the Theory of Planned Behavior significantly increased the knowledge along with all constructs of TPB in osteoporosis preventive behaviors.

Perceived Behavioral Control

Korean duty-free shops sales rank first among duty-free shops around the world (Generation Research, 2018) and have become a target of interest for academics and industry observers. In particular, attention has been focused on variables affecting the shopping behavior of this fast-growing segment of online duty-free shop users. In this research, the main variables of the technology innovation acceptance model and the target-oriented behavior model are added. Focus is placed on the decomposed theory of planned behavior, and the variables affecting the behavioral intention are identified. A survey is conducted with users of online duty-free shops (Internet, mobile) as targets, and an analysis of the structural equation model is utilized. Among the technology innovation acceptance variables, the factors affecting attitude are compatibility and perceived usefulness. It is determined that only perceived behavioral control has a significant effect on behavioral intention, which is a dependent variable of the decomposed theory of planned behavior, and the attitude and subjective norms are found to have a significant effect on both desire and behavioral intention. Thus, it is confirmed that attitude is a key variable in explaining this research model. This research has academic implications because it examines variables affecting the behavioral intention of online duty-free shop users by integrating the theory of technology innovation acceptance and the decomposed theory of planned behavior, with the addition of a desire variable. Moreover, there are practical implications in that online duty-free shop operators have provided meaningful basic data to establish differentiated marketing strategies from offline duty-free shops with the goal of expanding use. The results of this study are expected to serve as basic data for increasing the behavioral intention of online duty-free shop users and promoting the sustainable development of online duty-free shops in South Korea.

Lifestyle Related Diseases

BACKGROUND Health activities should be tailored to individual lifestyles and values. To raise awareness of practical health behaviors, various practices related to health education, such as interactive activities among individuals with different backgrounds, have been developed. Moreover, serious games have been used as a tool for facilitating communication. However, studies that investigated the mechanisms of behavioral intention change in relation to health through serious games based on the framework of the theory of planned behavior are few. OBJECTIVE The study aims to investigate the mechanisms of behavioral intention change among participants of various age groups after intervention using a serious game called “Negotiate Battle,” which is established to increase awareness of lifestyle-related diseases. METHODS Three age groups (i.e., adults, university students, and high school students) played the serious game and answered a questionnaire before, immediately after, and 2–4 weeks after the game. The questionnaire was composed of four factors according to the theory of planned behavior. The study employed structural equation modeling and compared the results of the three groups. RESULTS The study found that perceived behavior control was the key factor of behavioral intention change. Immediately after the game, causal relationship from perceived behavioral control to behavioral intention was enhanced or maintained for all groups. Analysis of free descriptions after intervention suggested that experiencing dilemma is related to learning and behavioral intention. CONCLUSIONS The study revealed that the serious game changed the behavioral intention of adolescents and adults regarding lifestyle-related diseases, and changes in perceived behavioral control mediated the alteration mechanism.

From an environmental standpoint, ecotourism has been drawn to attention by diverse communities all around the world. This empirical study aims to evaluate the behavioral intention of students by adopting an extended theory of planned behavior model by incorporating environmental concern and environmental knowledge from a developing country perspective. To get realistic output, structural equation modeling has been incorporated for systematic statistical analysis through using SMARTPLS 3.0, where data have been collected from 393 university students through a survey method. From an ecotourism point of view, a number of findings have been revealed in this study, such as students' attitude and perceived behavioral control have significant positive impacts on the behavioral intention towards ecotourism; results further proponed that environmental concerns have a significant effect on attitude, subjective norm, perceived behavioral control, and behavioral intention towards ecotourism, environmental knowledge had no significant effect on the behavioral intention towards ecotourism. Finally, it had a positive impact on attitude towards ecotourism, subjective norm, and perceived behavioral control. On the basis of constructive analysis, theoretical and practical implications are depicted in the form of a contribution of knowledge, which will add value to the decision-making process of various stakeholders.

Attitudes Toward Smoking

This study employed the Theory of Planned Behavior to examine the differences between adolescent ( n = 182) and young adults ( n = 209) in their intention to smoke and examined possible differences. Analysis showed that young adults had more positive self-reported attitudes toward smoking than adolescents, had higher intentions to smoke, lower perceived behavioral control over smoking and perceived they were more informed about smoking. The Theory of Planned Behavior provided good prediction of intention for both young adults ( R2 = .70, attitudes, information, and past behavior significant) and adolescents ( R2 = .68, attitudes, past behavior significant). For both samples attitudes were the strongest predictor of intentions to smoke. Implications for understanding intention toward smoking between adolescents and young adults are discussed.
