Factors influencing baby boomers' intention to choose a dish featuring plant-based meat alternatives (PBMA) at a restaurant: Findings from an online panel study.

The purpose of this study is to examine the psychosocial determinants of baby boomers'-born between 1946 and 1964- intention to choose a menu item featuring plant-based meat alternatives (PBMA) when dining out. The specific objectives are as follows: 1) to identify the baby boomer generation's health-related perceptions about PBMA, and 2) to examine the factors that influence baby boomers' intention to choose a dish featuring PBMA at a restaurant. A total of 174 responses obtained using the Qualtrics panel were analyzed with content analysis and partial least squares structural equation modeling (PLS-SEM). The findings identified various underlying perceptions of baby boomers toward PBMA, such as perceived health outcomes, perceived availability, and willingness to purchase. Furthermore, subjective norm, cues to action, and self-identity were found to be significant predictors of the intention to choose a menu item featuring PBMA when dining out. Theoretical and practical implications are discussed.

Evaluation of an Educational Intervention Based on Theory of Planned Behavior to Reduce Suicidal Ideation and Attempts in Drug Addicts Receiving Methadone: A Quasi-Experimental Study.

BACKGROUND: Drug addiction can lead to suicidal ideation or suicide attempt so that half of those who attempt suicide have a history of substance abuse. The purpose of this study was to investigate the effect of educational intervention based on Theory of Planned Behavior (TPB) on reducing suicidal ideation and suicide attempt of addicts. METHODS: A longitudinal quasi-experimental educational intervention was conducted on 200 methadone-treated addicts with suicidal ideation under the auspices of government addiction centers of Shiraz city from 2021 to 2022. Baseline data on demographic characteristics, suicidal ideation, and TPB questionnaire were collected from two groups at the beginning of the study and then three months after the intervention. The experiment group received educational intervention including sessions of individual and group counseling, training and organizational supports. The questionnaire was completed by both the experimental and control groups before the educational intervention and three months after the educational intervention. Data were analyzed using SPSS 22 software through independent t-test, Chi-square and paired t-test (p = 0.05). RESULTS: The mean age of addicts in the experimental and control groups was 38.80 ± 11.64 and 39.41 ± 11.18 years, respectively (p = 0.206). 22% of the experimental group and 18% of the control group had a history of suicide. According to the results, there was no significant difference between the experimental and control groups in terms of knowledge, attitude, subjective norms and perceived behavioral control before the educational intervention, however, the mentioned variables increased significantly in the experimental group three months after the educational intervention. There was no significant difference in suicide attempt and suicidal ideation between the experimental and control groups before the educational intervention, however, there was a significant change in the experimental group after the educational intervention. CONCLUSION: The results of the present study showed the effect of educational intervention on the knowledge, attitude, subjective norms, perceived behavioral control, suicidal ideation and suicidal attempt of addicts, thus confirming the effectiveness of the TPB-based intervention on reducing suicide of addicts.

Examining Individual and Service Delivery Context Variables and Their Association with the Effectiveness of QPR Suicide Prevention Gatekeeper Training.

Suicide prevention training programs have spread rapidly within child and public-serving organizations, due to the alarming increase in youth suicide rates. Yet, within these organizations, roles and responsibilities can shape attitudes and intentions related to suicide prevention, thereby influencing the uptake of prevention efforts. As such, various organizational and individual factors can predict uptake, adoption, and maintenance of prevention efforts (Fixsen et al., 2005). To date, few studies have examined the service delivery context in understanding training effectiveness, especially as it relates to QPR (Question Persuade and Refer), one of the most widely disseminated suicide prevention gatekeeper programs. The purpose of this longitudinal study was to evaluate whether individual and organizational characteristics influenced the effectiveness and sustainability of training outcomes, and whether such differences existed among diverse child and public-serving delivery sectors. Several training outcomes that align with the Theory of Planned Behavior (Ajzen, 1991) were examined, including confidence, attitudes, social norms, and suicide prevention behaviors. Measures were assessed prior to and 90 days after the QPR program among a sample of 858 professionals. Community support personnel uniquely showed improvements on social norms while juvenile justice and child welfare workers engaged in more suicide prevention behaviors post training. While trainees across sectors had improved suicide prevention attitudes, law enforcement personnel were the exception. Organizational climate predicted change in suicide prevention attitudes, confidence, and social norms. Trainees who were older, Latinx, and Black had the most improvement on several training outcome variables, but these findings also varied within service sectors.

Effect of educational intervention based on theory of planned behaviour on promoting preventive behaviours of oral cancer in rural women.

BACKGROUND: Oral cancer has created an alarming situation around the world, and being the 16th most common cancer worldwide, it has become a global concern. The present study aimed to investigate the effect of educational intervention based on a theory of planned behavior (TPB) on promoting preventive behaviors of oral cancer in rural women. METHODS: This quasi-experimental study was conducted on 120 female hookah users referring to rural health centers in Fasa and Shiraz city, Fars province, Iran. The subjects were divided into experimental and control groups by simple random sampling. The educational intervention for the experimental group consisted of 8 training sessions of 50 min. Both groups completed a questionnaire including demographic characteristics and constructs of TPB before and four months after the educational intervention. Data were analyzed using SPSS 22 software through independent t-test, chi-square, and paired t-test (p = 0.05). RESULTS: The mean age of the experimental and control group subjects were 41.12 ± 8.86 and 40.63 ± 9.62 years, respectively (p = 0.185). The mean age of onset of hookah use in the experimental and control group was 24.16 ± 9.50 and 23.35 ± 9.44 years, respectively (p = 0.182). Also, before the educational intervention, there was a significant difference between the experimental and control groups in terms of knowledge (p < 0.189), attitude (p < 0.122), perceived behavioral control (p < 0.142), subjective norms (p < 0.236), behavioral intention (p < 0.126), oral cancer prevention behaviors (p < 0.108) and nicotine dependence (p < 0.218); however, four months after the educational intervention, there was a significant increase in the experimental group in all variables except nicotine dependence (p < 0.005). CONCLUSION: Due to the alarming situation of oral cancer and the prevalence of hookah use among women, educational programs based on TPB could effectively prevent hookah use and oral cancer.

Do British and Chinese adolescents snack for different reasons? A cross-country study using the Theory of Planned Behaviour and eating styles.

Snacking is prevalent in adolescents and can have significant health impacts, but there is considerable individual and cross-country variation in determinants on adolescent snacking. The present study examined the role of eating styles (i.e. restrained eating, emotional eating, external eating, mindful eating) and the constructs of an extended Theory of Planned Behaviour (TPB) (i.e. attitudes, subjective norms, perceived behavioural control, habit strength) in predicting adolescent snacking, and the moderating effects of country. A survey was completed by adolescents aged 16-19 years from China (N = 182; mean age = 16.13, SD = 0.87) and England (N = 96; mean age = 17.04, SD = 0.74). Compared to British adolescents, Chinese adolescents showed higher restrained eating (p = .009), lower external eating (p = .004), less positive attitudes (p < .001) and subjective norms (p = .007) to, and less strong habit strength (p = .005) for unhealthy snacking. Mindful eating significantly predicted lower consumption of unhealthy snacks (p = .008) and beverages (p = .001), while restrained eating predicted higher consumption of fruit (p < .001) and vegetables (p < .001), regardless of country. Country showed significant moderating effects of TPB constructs on unhealthy beverages (p = .008) and fruit (p < .001) consumption, and effects on unhealthy snack (p = .023) and vegetable (p = .015) consumption approaching significance. Subjective norms predicted unhealthy snacking frequency regardless of country (p = .001). Habit strength predicted consumption of beverages (p < .001) and fruit (p < .001) only in English adolescents. Mindful eating may be a positive intervention approach to help reduce adolescent unhealthy snacking. TPB-based snacking interventions should carefully consider the country context. Acknowledging country-specific determinants of snacking are recommended.

Predicting intentions to get the COVID-19 vaccine in India: An integration of theory of planned behaviour and health belief model.

The aim of the study was to determine intention to receive Coronavirus disease-19 (COVID-19) vaccination in India. An integrated model of Theory of Planned behaviour (TPB) and Health Belief Model (HBM) was used. Online survey was conducted in Delhi NCR region to find out the intention to receive vaccination. Data was collected from 845 respondents during 15 February 2021-15 March 2021, just after COVID-19 vaccination became available in the India. Partial Least Square-Structural Equation Modelling was used to establish the relationships. The results of the analysis show that proposed framework is significant and explained 71% variance in intentions. Attitude, subjective norm, perceived behaviour control and self-efficacy from the TPB had direct (or significant independent) effects on intention and perceived benefits, perceived susceptibility from the HBM have indirect effect on the intentions through attitude. The present study can be used to maximise the uptake of vaccination in any future pandemic. This theoretically-driven model can be used to guide health policy makers and health care providers to increase the uptake of vaccination.

The risk-taking behavioural intentions of pilots in adverse weather conditions: an application of the theory of planned behaviour.

This paper examined pilots' risk-taking behavioural intentions based on the theory of planned behaviour, as well as the impact of experience on behavioural intentions in adverse weather conditions. Two hundred and seventy-three airline pilots and flying cadets were divided into two groups and asked to complete a questionnaire based on two decision-making scenarios. This questionnaire measured pilots' intentions to take risks, along with the attitude towards the behaviour, subjective norms, perceived behavioural control (PBC), risk perception, and self-identity. The results showed that attitude, subjective norm, PBC, and risk perception explained 52% of the variance in behavioural intentions. Additionally, pilots' risk-taking decisions can be influenced by experience. Inexperienced pilots had a relatively stronger intention to take risks and a more favourable attitude towards risky behaviour. Moreover, pilots were more likely to rely on their own direct experience in the decision-making process. Practitioner summary: This study examined the pilots' risk-taking intentions under adverse weather conditions using a questionnaire based on the TPB theory. Results demonstrated that the TPB model can be applied to the risk-taking scenario and that experience can influence pilots' decisions. These findings have implications for improving flight safety and lowering accident rates.

Development and Evaluation of the Teacher Reporting Questionnaire for South African Foundation Phase Educators (TRQ-SA) in Measuring Teachers' Intentions to Report Child Sexual Abuse Suspicions.

Globally teachers are mandated by law to report suspected child sexual abuse (CSA). The Teachers' Reporting Questionnaire (TRQ) was constructed to assess teachers' intentions to report CSA suspicions in Australia. The current research examines the development of the Teacher Reporting Questionnaire for South African foundation phase educators (TRQ-SA) and provides an evaluation of the TRQ-SA as a survey instrument for utilization in other studies. The TRQ-SA is a self-administered survey instrument used in a cross-sectional quantitative study that investigated teacher reporting intentions using the theory of planned behavior (TPB). A stratified random sample of 399 teachers from the eight school districts in the Western Cape province of South Africa was achieved. Before the TRQ-SA was developed, a qualitative elicitation study was conducted. Once developed, the questionnaire was pre-tested before the quantitative central study survey was administered. Cronbach's alpha was used to indicate reliability of scales, where a minimum α coefficient of .7 is considered acceptable. In the quantitative survey, the TRQ-SA had the following results: α = .74 was achieved for the attitude towards reporting scale, α = .78 for the subjective norm scale, α = .74 for the perceived behavioral control scale and α = .79 for the intention to report scale. The TRQ-SA achieved good internal consistency for all its TPB scales. The TRQ-SA is a valid and reliable survey instrument which could be used "as is" or amended in similar settings and countries testing the TPB in their own contexts.

A comparative study of eight COVID-19 protective measures and their impact on Swiss tourists' travel intentions.

A comparative vignette-based experimental survey design incorporating various socio-psychological factors, linked to the Theory of Planned Behavior (TPB), the Health Belief Model (HBM) and the Domain-Specific Risk-Taking scale (DOSPERT) was carried out to test variations in eight travel-related COVID-19 protective measures on Swiss tourists' travel intentions. Among the tested measures, vaccination passports, surgical masks and quarantining are those that stand out the most, with surgical masks having the greatest acceptance and willingness to adopt while traveling. Quarantining, on the other hand, appears to have a deterrent influence on travel intentions, and vaccination passports have the lowest perceived barriers during travel, but the highest perceived benefits in mitigating the spread of the infection. The discussion of individual differences has specific implications for tourism management against the background of our empirical findings.

What makes residents more willing to participate in source separation of waste masks under the COVID-19 pandemic?

With the outbreak of the novel coronavirus (COVID-19), the generation of a large amount of medical waste brought a rude shock to the existing solid waste management system. Since masks constitute the most common household medical waste under the COVID-19 pandemic, their effective collection and treatment can significantly reduce the potential risks for secondary transmission, and this concern has attracted worldwide attention. Taking Macau City as a case study, this research tried to identify factors that can influence residents' behavioral intentions toward the source separation of COVID-19 waste masks. The extended theory of planned behavior (TPB) model is used to examine the influence factors of the source separation behaviors of 510 respondents. The results show that the main factors that positively affected respondents' behavioral intentions toward waste-mask source separation are: cognitive attitude, convenience, and perceived behavioral control, and among these, cognitive attitude has the highest influence. Subjective norm is also proved to be the weak factor to improving behavioral intention. Policy advocacy, and demographic variables have no significant effect on behavioral intention. The results of this study can help decision makers and managers formulate effective strategies to increase residents' participation in the source separation of waste masks. Supplementary Information: The online version contains supplementary material available at 10.1007/s10163-022-01513-7.

Physical activity behavior during Covid 19 pandemic among Iranian dwellers in Southern Iran based on planned behavior theory: a SEM analysis.

BACKGROUND: The COVID-19 pandemic restrictions curtailed physical activity. The current study applied an integrated Theory of Planned Behavior to identify the determinants of physical activity behavior and the processes involved in the COVID-19 pandemic. METHODS: A cross-sectional study was conducted in Shiraz city, Southern Iran, among 2500 people who met the inclusion criteria were included in the study. Data were collected using the demographic information questions and questionnaire based on the Theory of Planned Behavior (TPB) constructs. The Questionnaire via WhatsApp, emails, and SMS was shared. Data analysis was performed using SPSS26 and Amos version 24. Mean and standard deviation was used to describe the data. Also, one-way ANOVA and structural equation analysis were used to analyze the data. The significance level in all the tests was considered to be 0.05. RESULTS: One thousand one hundred sixty-nine samples (46.8%) said they had been exercising less than 3 days a week, and 47.6% of them did not have any exercise or physical activities (n = 1191). The mean score of attitudes, SN, PBC, and intention were 9.38 ± 2.07, 9.27 ± 2.03, 9.32 ± 2.05, and 12.29 ± 2.35, respectively. The effect size values demonstrate the independent variables' high coefficient of influence on explaining the theoretical model. According to the results, the factors play an important role in samples' intention (η2 ≥ 0.2, p ≤ 0.05). The effect size of intention on doing physical activities and exercise during the SARS-CoV-2 pandemic is Eta square = 0.777, which means the measure was high. The obtained model was good based on the main goodness of fit indices (Chi2 = 108.6, df = 25, n = 2500, Chi2/df = 4.344, RMSEA = 0.036, AGFI = 0.92, CFI = 0.95, GFI = 0.90, Fornell-Larcker criterion = 0.87, HTMT = 0.89). CONCLUSION: The TPB provides a useful framework to explore psychosocial determinants of physical activity behavior during the pandemic and identify key strategies for program planning aimed at improving exercise among people who were already influenced by quarantine and lockdown restrictions.

Menu labeling influence on purchase behaviors: Applying the theory of planned behavior and health consciousness.

Mixed findings have been reported in the literature on the effectiveness of menu labeling in assisting consumers to make informed purchase decisions when eating out. Therefore, this study examined factors that influenced consumers' intentions to use menu labeling and whether these intentions influenced caloric purchases relative to actual caloric needs. While other researchers have assessed impacts of menu labeling on total calories purchased, our study assessed the impact relative to caloric needs, therein recognizing that each consumer has different caloric needs. An extended theory of planned behavior (TPB) incorporating health consciousness served as the theoretical underpinning. The TPB addresses reasons why an individual takes action on a certain behavior; in the case of this research, that behavior was purchasing food. Food purchases were further operationalized using the calorie content of foods and comparing that number of calories to caloric needs. Two-step structural equation modeling was used to analyze 316 surveys from restaurant consumers. Results indicated that attitudes, subjective norms, and health consciousness positively influenced intentions to use menu labeling. Intentions to use menu labeling also significantly influenced actual purchase behaviors (measured as the difference between caloric purchases and caloric needs). Overall, the current research findings provide novel insights for researchers to further explore the role of menu labeling on purchase behavior by using the TPB model with integration of health consciousness.

U.S. Political Partisanship and COVID-19: Risk Information Seeking and Prevention Behaviors.

The global pandemic caused by SARS-CoV-2 (COVID-19) poses serious health risks to humans; yet, despite recommendations by governments and health organizations, a significant number of Americans are not engaging in preventive behaviors. To understand and explain this phenomenon, we seek guidance from a theoretical model that merges the risk information seeking and processing model and the theory of planned behavior. Furthermore, given the politicized nature of the pandemic in the U.S., we pose different information seeking patterns according to media partisanship, asserting that partisanship is likely to affect cognitive structures regarding COVID-19 decision making. Our results suggest two distinct routes for information seeking to decision-making. Conservative media use is directly associated with preventive behavior avoidance, while liberal media use is indirectly associated with preventive behavior engagement. This work contributes to our collective understanding of what drives preventive behaviors in the context of health risk, particularly in the case of a highly politicized national health crisis with global implications.

Patient Trust in Physicians Matters-Understanding the Role of a Mobile Patient Education System and Patient-Physician Communication in Improving Patient Adherence Behavior: Field Study.

BACKGROUND: The ultimate goal of any prescribed medical therapy is to achieve desired outcomes of patient care. However, patient nonadherence has long been a major problem detrimental to patient health and, thus, is a concern for all health care providers. Moreover, nonadherence is extremely costly for global medical systems because of unnecessary complications and expenses. Traditional patient education programs often serve as an intervention tool to increase patients' self-care awareness, disease knowledge, and motivation to change patient behaviors for better adherence. Patient trust in physicians, patient-physician relationships, and quality of communication have also been identified as critical factors influencing patient adherence. However, little is known about how mobile patient education technologies help foster patient adherence. OBJECTIVE: This study aimed to empirically investigate whether and how a mobile patient education system (MPES) juxtaposed with patient trust can increase patient adherence to prescribed medical therapies. METHODS: This study was conducted based on a field survey of 125 patients in multiple states in the United States who have used an innovative mobile health care system for their health care education and information seeking. Partial least squares techniques were used to analyze the collected data. RESULTS: The results revealed that patient-physician communication and the use of an MPES significantly increase patients' trust in their physicians. Furthermore, patient trust has a prominent effect on patient attitude toward treatment adherence, which in turn influences patients' behavioral intention and actual adherence behavior. Based on the theory of planned behavior, the results also indicated that behavioral intention, response efficacy, and self-efficacy positively influenced patients' actual treatment adherence behavior, whereas descriptive norms and subjective norms do not play a role in this process. CONCLUSIONS: Our study is one of the first that examines the relationship between patients who actively use an MPES and their trust in their physicians. This study contributes to this context by enriching the trust literature, addressing the call to identify key patient-centered technology determinants of trust, advancing the understanding of patient adherence mechanisms, adding a new explanation of the influence of education mechanisms delivered via mobile devices on patient adherence, and confirming that the theory of planned behavior holds in this patient adherence context.

Factors influencing farmer and resident willingness to adopt an agri-environmental scheme in Israel.

Providing for growing food demand while minimizing environmental degradation is a major contemporary environmental challenge. Agri-environmental schemes (AESs) are often promoted to meet this challenge by providing subsidies to farmers who adopt agri-environmental practices (AEPs). The success of these schemes depends on the ability to engage farmers, thus understanding farmers' perceptions about AEPs is pivotal. Yet, current knowledge is limited as most research explores farmer's attitudes towards existing AESs, often based on subsidies. We explored the attitudes of farmers and their communities towards five different AEPs, and towards a potential AES, in an area of intensive agriculture in Israel, where currently no AES are implemented. We conducted five focus group sessions with 41 farmers, 12 follow-up interviews, and a survey with 296 community members. Findings indicate that farmers' willingness to implement AEPs was driven by environmental, personal, and social considerations, particularly perceptions of "good farming" practices, such as community cohesiveness and maintaining control of one's field. Farmers' lack of trust in the government, and lack of personal or local experience with specific AEPs, are other major barriers for joining a potential AES. Farmers perceived financial compensation as a safety net, but placed social and cultural values on par with, or above, financial considerations for joining an AES. Farmers' communities demonstrated high support for implementing AEPs, indicating that communities could be an asset for AES development. Therefore, while incentives for many AESs are based primarily on monetary compensation, to achieve their desired long-term results they should also focus on farmer resilience, independence, knowledge creation, and socio-cultural capital development.

Small RNA-directed DNA elimination: the molecular mechanism and its potential for genome editing.

Transposable elements have both detrimental and beneficial effects on their host genome. Tetrahymena is a unicellular eukaryote that deals with transposable elements in a unique way. It has a separate somatic and germline genome in two nuclei in a single cell. During sexual reproduction, a small RNA directed system compares the germline and somatic genome to identify transposable elements and related sequences. These are subsequently marked by heterochromatin and excised. In this Review, current knowledge of this system and the gaps therein are discussed. Additionally, the possibility to exploit the Tetrahymena machinery for genome editing and its advantages over the widely used CRISPR-Cas9 system will be explored. While the bacterial derived CRISPR-Cas9 has difficulty to access eukaryotic chromatin, Tetrahymena proteins are adept at acting in a chromatin context. Furthermore, Tetrahymena based gene therapy in humans might be a safer alternative to Cas9 because the latter can trigger an immune response.

The effect of educational program based on beliefs, subjective norms and perceived behavior control on doing pap-smear test in sample of Iranian women.

OBJECTIVE: Cervical cancer is considered treatable as long as it is detected early and managed effectively. Pap smear test is a screening tool that plays an important role in the early detection, prevention and can prevent any early cervical cell changes from becoming cancer. This study aims to survey the effect of educational programs based on beliefs, subjective norms, and perceived behavior control on doing the pap-smear test in a sample of Iranian women. MATERIALS AND METHODS: This experimental interventional study was performed on 300 women admitted to Fasa City, Fars Province, Iran health centers in 2018-2019. A questionnaire consisting of demographic information, knowledge, Health Belief Model, and Theory of Planned Behavior constructs were used to measure on doing of Pap smear test in women before and after 6 months' educational intervention. RESULTS: The results revealed that 6 months after the intervention, 108 women (72%) in the experimental group and only 9 women (6%) in the control group received the Pap smear test. CONCLUSIONS: The current research results revealed that education based on the combination of the health Belief model and theory of planned behavior might be promoting participation and an increasing rate of receiving Pap smear tests in women.

Effect of educational program based on theory of planned behavior on promoting nutritional behaviors preventing Anemia in a sample of Iranian pregnant women.

BACKGROUND: Iron deficiency anemia (IDA) is one of the most common problems during pregnancy. The aim of this research was to determine the effect of educational program based on Theory of Planned Behavior (TPB) on promoting nutritional behaviors preventing anemia in a pregnant woman in Shiraz city, Iran. METHODS: This quasi-experimental study was done on 150 pregnant women (75 experimental and 75 control groups) who were selected using randomly sampling method in in Shiraz city, Iran, in 2020-2021. The educational intervention for the experimental group included six educational sessions for 50 or 55 min-based TPB model. A questionnaire consisted of items about demographic information, TPB constructs (attitude, perceived behavioral control, subjective norms and behavioral intention) was used to measure the nutritional behaviours preventing iron deficiency anemia in pregnancy women before and 3 months after the intervention. RESULTS: The results showed that before the educational intervention, there was no significant difference between the two groups in terms of knowledge, attitude, perceived behavioral control, subjective norms, behavioral intention and nutritional performance; however, three months after the educational intervention, the experimental group showed a significant increase in each of the mentioned variables. For example the mean and standard deviation score of behavioral intention after intervention in the experimental group was significantly increased (25.57 ± 1.66, P = 0.001),and the mean and standard deviation score of performance after intervention in the experimental group was significantly increased (31.03 ± 2.19, P = 0.001), (P < 0.05). CONCLUSIONS: After the educational intervention, the experimental group showed a significant increase in of the knowledge, attitude, perceived behavioral control, subjective norms, behavioral intention and nutritional performance. Therefore the results of the study showed positive effect of nutrition educational intervention program base on TPB model on improvement of iron deficiency anemia preventive behaviours in the pregnancy women.

Help-seeking intention among Chinese college students exposed to a natural disaster: an application of an extended theory of planned behavior (E-TPB).

PURPOSE: Professional mental health help-seeking is generally low among Chinese populations with mental problems, and this may also the case following natural disasters. The help-seeking intention within Chinese populations exposed to natural disaster remain unclear. This study aims to explore the intention to seek professional mental health help utilizing an extended theory of planned behavior (E-TPB) model among Chinese college students exposed to Typhoon Hato. METHODS: In total, 1876 Chinese participants were recruited using convenience sampling at baseline and 817 participants (mean age = 20.9 years, SD = 2.8, 28.4% male) were followed up 6 months later. The online questionnaire was applied to measure six constructs including help-seeking intention, attitude, subjective norm, perceived behavioral control, self-stigma, and social stigma. RESULTS: Structural equation modeling showed the subjective norm (ß = 0.374, p < 0.001) was the strongest predictor of help-seeking intention, followed by attitude (ß = 0.271, p < 0.001) and perceived behavioral control (ß = 0.213, p < 0.001), and self-stigma (ß = - 0.117, p = 0.006). Unexpectedly, public stigma was not significantly associated with help-seeking intention. Moreover, multi-group analyses revealed paths of the E-TPB model were invariant across gender. CONCLUSION: These results supported the efficacy of the E-TPB model in explaining help-seeking intention and emphasized the importance of subjective norm (e.g., support or disproval from significant others or society) in influencing help-seeking intention among Chinese young adults exposed to a natural disaster.

Consumer's over-ordering behavior at restaurant: Understanding the important roles of interventions from waiter and ordering habits.

In China, approximately half of total food waste is generated from the foodservice sector, which largely results from irresponsible consumer behavior when ordering food. Therefore, the purpose of this study was to better understand and intervene in Chinese consumers' ordering behavior in restaurants, ultimately contributing to minimizing food waste in China. Thus, the current study proposed a comprehensive model which incorporated habitual processes (individual ordering habits) and situational constraints (interventions from waiters) into the original theory of planned behavior (TPB) and the norm-activation (NAM) theoretical framework. This comprehensive model was tested on a sample of 527 consumers from Mainland China and was compared with the more mature models: TPB, NAM, and a combined model of both. Results showed that the comprehensive model explained the highest degree of variation in over-ordering behavior. Individual ordering habits and interventions from the waiter were proven to be crucial in understanding the complicated decision-making process of ordering foods in restaurants. Based on the model, implications for research and practice are also discussed.
