The Health Belief Model in predicting healthcare workers' intention for influenza vaccine uptake in Jordan

The moderating influence of celebrity endorsement on intention to engage in infection prevention behaviours

Although the use of celebrities for communication within social marketing to influence voluntary behaviour change has received significant attention, its application to promote infection preventive behaviours, such as frequent handwashing with soap, has received limited attention. Using the health belief model (HBM), the study examined the moderating effect of celebrity endorsement (CE) on the relationship between the predictors of HBM such as perceived severity, susceptibility, benefits, barriers, self-efficacy and target audiences' intention to avoid handshaking, frequently wash hands with soap and cover mouth with an elbow when coughing. Data from 562 respondents were analysed using PLS-SEM. The result shows that CE significantly moderate the relationship between target audiences' perception of severity, susceptibility, self-efficacy and cues to action and intention to perform the recommended infection preventive behaviours. Thus, when a celebrity is employed as a conduit for delivering a social marketing message, particularly about infection preventive behaviour, target audiences are more likely to take action to perform the recommended behaviour. Theoretically, the study shows that although the HBM has been extensively applied to explain health-related behaviours, using celebrities to endorse the various constructs of the HBM significantly enhances the predictive ability of the model.

Influenza Vaccination of Romanian Medical Students and Resident Physicians-A Matter of Accessibility

In Romania, influenza vaccination of healthcare professionals is recommended, but not mandatory. This study aims to investigate the attitudes and behaviors of medical students and resident physicians-the youngest healthcare professionals-towards influenza immunization, focusing on the barriers and facilitators, as well as on the impact of the COVID-19 pandemic. An anonymous online survey was conducted during the 2021/2022 influenza season, with responses from332 medical students and resident physicians. The majority (73.5%) were not vaccinated against influenza (68% of the students, 52.3% of the residents), although they were vaccinated against COVID-19 (94% students, 94.8% resident physicians) and believed that the pandemic positively influenced their attitude towards influenza vaccination. Vaccine accessibility (p < 0.001) and the necessity to pay for vaccination (p < 0.001) were identified as barriers in both groups, while lack of recommendation from a medical professional/teacher was significant only for students (p < 0.001). Forgetfulness and lack of prioritizations were the most cited reasons for not being vaccinated. These barriers could be diminished through proactive recommendation and simplification of the vaccination process, with accessible vaccination centers and implementation of vaccine reimbursement policies. Improved vaccination rates in young medical professionals are of the utmost importance both in their professional settings and as a model for the general population.

Determinants of influenza and COVID-19 vaccine intent or uptake in Lebanon: a scoping review of the literature

BACKGROUND

Vaccination is essential to protect from influenza and recently from COVID-19, yet uptake in Lebanon is suboptimal. Several factors determine uptake including knowledge, attitude and policies. We conducted a scoping review of the literature to explore the determinants of influenza and COVID-19 vaccine intent or uptake in Lebanon.

METHODS

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines, thirty one peer reviewed studies indexed in six databases Pub Med, EMBASE, Scopus, CINAHL, Medline, and the Cochrane Library were screened. Two students, a senior Librarian and an Associate Professor in nursing searched for eligible studies. The library search strategy followed a combination of three broad concepts (viral influenzas; vaccines; Lebanon). The search timeframe was up till December 31, 2022. Determinants of influenza and COVID-19 vaccine intent or uptake were categorized following the constructs of the Theory of Planned Behavior.

RESULTS

Nine studies investigated influenza vaccine intent or uptake among the public community, parents and healthcare workers. Twenty one studies investigated COVID-19 vaccine intent or uptake among the public community, older refugees, university students, patients with cancer, dentists, and social media users. One study investigated both types of vaccines. A conceptual model of the determinants of vaccine intent and uptake within the Lebanese context was developed. Various determinants included environmental factors, norms, knowledge, perceptions, attitudes, past experiences, behavioral control and hesitancy.

CONCLUSIONS

Research on vaccine intent and uptake in Lebanon is still in its infancy, while that of COVID-19 is on the rise. Multifaceted reasons behind the low vaccination rates were observed yet few attempts were made to target vulnerable groups. Further research studies are needed to target vulnerable groups.

Why should I vaccinate? The role of mindfulness and health-protective behaviours during the COVID-19 pandemic

Objective

Health maintenance of the general public through vaccination is a significant component of controlling the COVID-19 pandemic. This study aims to examine the perception of Nigerians toward the COVID-19 vaccine. Methods: Informed by the Extended Parallel Process Model (EPPM), 793 Nigerian participants completed a cross-sectional self-administered online survey to assess: (1) their perception of COVID-19 based on fear-mongering information on social media (2) the potential relationship between threat perception, efficacy, and fear associated with the COVID-19 vaccine, vaccine hesitancy, and attitudes toward the decision to uptake the vaccine using structural equation modeling (SEM) analysis, and (3) we further employed the use of the hierarchical regression analysis to test the moderating effect of mindful critical thinking between vaccine hesitancy and attitudes toward vaccines.

Results

Most participants (65.7%) intend to uptake the COVID-19 vaccine. However, many people did not fear the disease (19.2%). Threat perception and efficacy were associated with a decision to uptake the COVID-19 vaccine via the mediation of attitudes toward vaccines. Previous vaccine hesitancy has no relationship with uptake decisions. The hierarchical regression analysis showed that participants exhibiting high critical thinking mindfulness were more interested in taking the vaccine.

Conclusions

The findings of this study demonstrate that EPPM constructs are effective predictors of the public's decision to uptake the COVID-19 vaccine. This research highlights the theoretical and practical implications.

Uptake of Influenza Vaccine and Factors Associated with Influenza Vaccination among Healthcare Workers in Tertiary Care Hospitals in Bangladesh: A Multicenter Cross-Sectional Study

Influenza, highly contagious in hospital settings, imposes a substantial disease burden globally, and influenza vaccination is critical for healthcare workers (HCWs) to prevent this illness. This study assessed influenza vaccine uptake, including its associated factors among HCWs of tertiary care hospitals in Bangladesh. Between September and December 2020, this multicenter study included 2046 HCWs from 11 hospitals. Face-to-face interviews were conducted using a semi-structured questionnaire to collect data from physicians, nurses, and cleaning and administrative staff for the survey. Only 13.8% (283/2046) of HCWs received the influenza vaccine, of which the majority (76.7%, 217/283) received it for free from the hospital. Nurses had the highest (20.0%, 187/934) influenza vaccine coverage, followed by physicians at 13.5% (71/526), whereas cleaning staff had the lowest at 6.0% (19/318). Among unvaccinated HCWs, the desire to get vaccinated was high (86.2%), with half of the respondents even being willing to pay for it. The HCWs who were aware of the influenza vaccine were over five times more likely to get the vaccine (OR 5.63; 95% CI: 1.04, 1.88) compared to those who were not. HCWs in Bangladesh were vaccinated against influenza at a very low rate. Free and mandatory influenza vaccination programs should be initiated to optimize vaccine coverage among HCWs.

Health Belief Model Constructs Affect Influenza Vaccine Uptake in Kidney Transplant Recipients

This secondary analysis explored how the constructs of the health belief model affect influenza vaccine uptake in kidney transplant recipients (KTRs). In the parent study, a total of 180 KTRs were recruited at an organ transplant center in South Korea. A nonlinear path analysis using generalized structural equation modeling was performed. Previous influenza vaccination had a direct effect on their behavior, while cues to action alone did not directly affect their behavior. Perceived benefits played a key role as a mediator in improving influenza vaccine uptake in KTRs. This study highlights the need for health professionals to assess perceived benefits at the individual level and provide patient-centered interventions based on a consideration of theoretical mechanisms. As cues to action, recommendations for recipients’ first vaccination after kidney transplant should focus on changing patients’ perceptions of benefits by emphasizing the positive aspects of the influenza vaccine for immunosuppressed patients.

Factors of COVID-19 Vaccination among Hong Kong Chinese Men Who Have Sex with Men during Months 5–8 since the Vaccine Rollout—General Factors and Factors Specific to This Population

This study investigated an under-researched topic regarding the prevalence of COVID-19 vaccination behavior among Chinese men who have sex with men (MSM) and the associations of this with general and MSM-specific perceptions grounded in the health belief model (HBM) and the theory of planned behaviors (TPB). A total of 400 Chinese MSM were recruited from multiple sources (site recruitment, online recruitment, and peer referral) in Hong Kong from July to October 2021, who then participated in a structured telephone interview. Of all the participants, the prevalence of COVID-19 vaccination (i.e., taking at least one dose of COVID-19 vaccination) was 78.3%. Multivariable logistic regression analyses showed that, after adjusting for background factors, (1) the general and MSM-specific HBM variables of perceived benefits and self-efficacy were positively associated with COVID-19 vaccination behavior; (2) the items or scale of general/MSM-specific perceived barriers and social norms were negatively associated with COVID-19 vaccination behavior; (3) the general perceived severity and MSM-specific perceived susceptibility, perceived severity, and cue to action were not significantly associated with COVID-19 vaccination behavior. The findings suggest that the HBM and social norm construct of the TPB only partially explained the participant’s COVID-19 vaccination behavior. Health promotion may need to focus more on modifying perceptions related to COVID-19 vaccination rather than COVID-19.

Regional Disparities in COVID-19 Vaccine Hesitancy: The Moderating Role of Social Distancing and Vaccine Rollout in the U.S

This study examines the relationship between statewide contexts and individuals’ COVID-19 vaccine hesitancy by using the Household Pulse Survey, a national and near real-time data timely deployed by the U.S. Census Bureau. Controlling for the individual- and state-level variables in addition to temporal effect, this study finds that racial and ethnic minorities and COVID-19-infected people are more hesitant than their counterparts to receive a vaccine. Individuals who reside in a state where more stringent social distancing measures – particularly mask mandate – are implemented and vaccine rollout conditions are better appear to be less hesitant to receive a COVID-19 vaccine. Vulnerable subpopulation groups such as people of color and COVID-19-infected individuals are more hesitant to vaccine uptake even if regional circumstances are equal. These findings suggest that the continuation and extension of vaccine campaigns at the regional as well as individual levels are all important for expediting COVID-19 vaccination and reducing vaccine hesitancy as the world is in the middle of the third year of the pandemic.

The Role of Psychological Factors and Vaccine Conspiracy Beliefs in Influenza Vaccine Hesitancy and Uptake among Jordanian Healthcare Workers during the COVID-19 Pandemic

Vaccination to prevent influenza virus infection and to lessen its severity is recommended among healthcare workers (HCWs). Health professionals have a higher risk of exposure to viruses and could transmit the influenza virus to vulnerable patients who are prone to severe disease and mortality. The aim of the current study was to evaluate the levels of influenza vaccine acceptance and uptake as well as its determinants, among Jordanian HCWs over the last influenza season of 2021/2022. This study was based on a self-administered electronic survey that was distributed in March 2022. Psychological determinants of influenza vaccine acceptance and vaccine conspiracy beliefs were assessed using the previously validated 5C scale questionnaire (confidence, complacency, constraints, calculation and collective responsibility) and the vaccine conspiracy beliefs scale. The study sample comprised a total of 1218 HCWs: nurses (n = 412, 33.8%), physicians (n = 367, 30.1%), medical technicians (n = 182, 14.9%), pharmacists (n = 161, 13.2%) and dentists (n = 87, 7.1%), among others. About two-thirds of the study sample expressed willingness to receive influenza vaccination if provided free of charge (n = 807, 66.3%), whereas less than one-third were willing to pay for the vaccine (n = 388, 31.9%). The self-reported uptake of the influenza vaccine in the last influenza season was 62.8%. The following factors were significantly associated with higher acceptance of influenza vaccination if provided freely, as opposed to vaccine hesitancy/rejection: male sex; physicians and dentists among HCW categories; higher confidence and collective responsibility; and lower complacency, constraints and calculation. Higher influenza vaccine uptake was significantly correlated with nurses and physicians among HCW categories, older age, a higher monthly income, higher confidence and collective responsibility, lower complacency and constraints and lower embrace of general vaccine conspiracy beliefs. The results of the current study can provide helpful clues to improve influenza vaccine coverage among HCWs in Jordan. Consequently, this can help to protect vulnerable patient groups and reserve valuable resources in healthcare settings. Psychological determinants appeared to be the most significant factors for vaccine acceptance and uptake, whereas the embrace of general vaccine conspiracy beliefs was associated with lower rates of influenza vaccine uptake, which should be considered in educational and interventional measures aiming to promote influenza vaccination.

Prevalence and factors of influenza vaccination during the COVID-19 pandemic among university students in China

BACKGROUND

Previous outbreaks of emerging infectious diseases (e.g., SARS) had increased the uptake of influenza vaccination (IV). It is uncertain whether such was also true for COVID-19. This study hence investigated prevalence of IV behavior/intention prior to and during the COVID-19 pandemic and associated cognitive factors.

METHODS

A self-administered, online, and anonymous cross-sectional survey was conducted among 6,922 university students of five provinces in China during November 1-28, 2020 (response rate: 72.3%).

RESULTS

Of all the participants, 35.1% self-reported behavioral intention of IV (next 12 months), while 62.9% reported an increased intention of IV due to COVID-19. However, only 4.7% and 2.9% had taken up IV during the 12-month period prior to the outbreak (1/2019-12/2019) and during the COVID-19 outbreak (1-11/2020), respectively. Adjusted for the background factors, the multivariable logistic regression analysis showed that in general the COVID-19 related perceptions (perceived susceptibility, perceived severity, and perceived chance of having another wave of COVID-19 outbreak) were significantly and positively associated the IV behavior (during the COVID-19 outbreak) and intention of IV uptake in the next 12 months.

CONCLUSIONS

The COVID-19 pandemic may have influenced actual behavior and intention of IV uptake among university students during the pandemic. Efforts are warranted to reduce the intention-behavior gap of IV uptake; modification of perceived susceptibility and perceived severity regarding COVID-19 may help. Future longitudinal and intervention studies are needed to confirm the findings of this study and explore other factors affecting IV uptake during the COVID-19 period.

Factors Associated with COVID-19 Vaccine Acceptance in Morocco: Applying the Health Belief Model

To identify factors that influenced Moroccans’ intention to get a COVID-19 vaccine, a cross-sectional survey among a Moroccan sample was conducted based on Health Belief Model constructs. Participants’ sociodemographic characteristics, perceived susceptibility, perceived severity, perceived barriers, perceived benefits, self-efficacy, cues to action, and intention to receive vaccine data were collected and analyzed using a structural equation model (SEM). The survey was completed by 3800 individuals; 57.2% were men, 44.5% were aged 30 to 44, and 44.6% were married. After controlling for confounders, being a woman and having a chronic disease were associated with higher acceptance of the COVID-19 vaccine. The strongest predictor for the intention of receiving a vaccine was participants who were married. Most of the HBM constructs were shown to be significantly associated with vaccine acceptance. Susceptibility and Benefits were the strongest predictors of acceptance of the COVID-19 vaccine (standardized path coefficient, SPC = 0.23), followed by Severity (SPC = 0.22). Conversely, given the negative correlation between barriers and intention (SPC = −0.08), it is necessary to maintain a high level of transparency regarding the vaccines’ safety. Our study provides guidance for an implementation of vaccination strategies, intending to bolster the overall COVID-19 immunization program.

Using Integrative Behavior Model to Predict COVID-19 Vaccination Intention among Health Care Workers in Indonesia: A Nationwide Survey

Background: Health care workers (HCWs) are a high-priority group for COVID-19 vaccination for several reasons. Health behavior theory-based studies on the intention or acceptability of COVID-19 vaccination among Indonesian HCWs is lacking. Using an integrated behavioral model, this research sought to identify Indonesian health care workers' intentions to obtain COVID-19 vaccines. Methods: A countrywide cross-sectional questionnaire-based survey was conducted. The questionnaire was constructed on the basis of IBM (integrated behavioral model) constructs and scored on a seven-point bipolar scale. A hierarchical multivariable regression was used to evaluate the fit of the predictor model as well as the correlations between variables in the study. Results: 3304 people responded to the survey. A model combining demographic and IBM characteristics predicted 42.5 percent (adjusted R2 = 0.42) of the COVID-19 vaccination intention. Vaccination intention was associated with favorable vaccine attitudes, perceived norms, and self-efficacy. Among the determining constructs, behavior belief predicted vaccination intention the best. Being female, being married, having a history of COVID-19 infection, living outside Java Island, and having a low income were all linked to lower vaccination intentions. Conclusions: This study confirms the IBM model's robustness in predicting health care workers' intention to vaccinate against COVID-19.

COVID-19 Vaccination Behavior Among Frontline Healthcare Workers in Pakistan: The Theory of Planned Behavior, Perceived Susceptibility, and Anticipated Regret

Healthcare workers in Pakistan are still fighting at the frontline to control the spread of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and have been identified as the earliest beneficiaries for COVID-19 vaccination by the health authorities of the country. Besides, the high vaccination rates of frontline healthcare workers (FHWs) are essential to overcome the ongoing pandemic and reduce the vaccines hesitancy among the general population. The current research employed the theory of planned behavior (TPB) to investigate the COVID-19 vaccination behavior among FHWs in Pakistan as well as the predictors of such behavior. Following the epidemic control and prevention policies, a sample of 680 FHWs were accessed to fill in the questionnaire evaluating the components of the TPB. Moreover, the potential role of anticipated regret (AR) and perceived susceptibility (PS) on COVID-19 vaccination behavior was also assessed. The partial least square structural equation modeling (PLS-SEM) results revealed that the TPB components, as well as the AR, have positive associations with the COVID-19 vaccination behavior. The results further confirmed that PS positively affects the anticipated regret, attitude (ATT), and subjective norm (SN) to vaccinate against SARS-CoV-2. The perceived susceptibility also has a positive association with COVID-19 vaccination behavior through the mediation of anticipated regret, ATT, and SN. Our findings highlighted the importance of COVID-19 vaccination among healthcare workers, which can be applied to reduce vaccine hesitancy among the general public.

COVID-19 Vaccine Hesitancy among Adolescents: Cross-Sectional School Survey in Four Chinese Cities Prior to Vaccine Availability

To address the novel coronavirus disease (COVID-19) pandemic, development and regulatory evaluations have been accelerated for vaccines, authorizing emergency use. To anticipate vaccine preparedness in adolescents, we studied COVID-19 vaccination awareness and willingness to vaccinate before the vaccine became available. We conducted a cross-sectional survey among 9153 (4575 boys, 50%) students with a mean age of 14.2 years old in four cities in China to collect information on demographic characteristics and their COVID-19 vaccination concerns. Multinomial logistic regression was used to analyze the influencing factors of vaccine hesitancy (“not sure”) and resistance (“do not want it”). The results showed that 2891 (31.6%) were hesitant and 765 (8.4%) were resistant to being vaccinated. Additionally, multivariable analyses showed that vaccine hesitancy and vaccine resistance were associated with living in the Beijing area (OR = 1.62; 95% CI: 1.40–1.88; OR = 1.81; 95% CI: 1.44–2.28), lack of influenza vaccination experience (OR = 1.33; 95% CI: 1.14–1.55; OR = 1.57; 95% CI: 1.25–1.98), no perceived susceptibility (OR = 1.72; 95% CI: 1.50–1.97; OR = 3.57; 95% CI: 2.86–4.46), and perceiving no cues to action (OR = 3.24; 95% CI: 2.56–4.11; OR = 27.68; 95% CI: 21.81–35.13). Postulating a highly effective vaccine (OR = 0.84; 95% CI: 0.72–0.98; OR = 0.66; 95% CI: 0.52–0.83) decreased both vaccine hesitancy and resistance. Vaccine hesitancy alone was associated with girls (OR = 1.21; 95% CI: 1.09–1.36) and was less common among students boarding at school (OR = 0.79; 95% CI: 0.68–0.92), postulating convenient vaccine access (OR = 0.84; 95% CI: 0.73–0.96), and having doctors’ recommendation (OR = 0.86; 95% CI: 0.76–0.98). In conclusion, the results of the study showed that vaccine hesitancy among students in China was associated with limited health literacy and lower risk awareness. Our findings in China suggest that educating youth regarding COVID-19 and the safety and effectiveness of immunization help reduce concerns and increase vaccine confidence and acceptance.

Determinants of acceptance of Coronavirus disease-2019 (COVID-19) vaccine among Lebanese health care workers using health belief model

Since Health care workers (HCWs) are at high occupational risk for COVID-19, they are prioritized for immunization. This study aimed to assess the acceptance rate of the COVID-19 vaccine among HCWs and to identify its determinants. A web-based cross-sectional study was conducted between10 and 31 December 2020 among Lebanese HCWs. The Health Belief Model (HBM) was used as a theoretical framework. Multivariable logistic analyses were carried out to identify the factors associated with the acceptance of the COVID-19 vaccine among HCWs. A total of 1800 HCWs have completed the survey. Around half (58.10%) of them were frontline HCWs and aged between (30-49) years old. Over two-thirds (67.33%) of the participants have received the seasonal influenza vaccine. The acceptance rate of the COVID-19 vaccine among surveyed HCWs was 58%. HCWs who were male (aOR = 1.99, 95% CI (1.41-2.80)), working in the frontlines (aOR = 1.61, 95% CI (1.17-2.21), and those who have received influenza vaccination for the current year (aOR = 1.38, 95% CI(0.99-1.92)) were more willing to get the COVID-19 vaccine. However, factors such as living in rural areas (aOR = 0.61, 95% CI (0.44-0.84)), and being previously diagnosed with COVID-19 (aOR = 0.66, 95%CI (0.45-0.96) were found negatively associated with vaccine acceptance. In terms of health beliefs items, concerns related to the novelty of vaccine (aOR = 0.42, 95% CI (0.25-0.71)), side effects/vaccine safety (aOR = 0.41, 95% CI (0.23-0.73), reliability of manufacturer (aOR = 0.43, 95% CI (0.30-0.63)), and the number of required doses (aOR = 0.58, 95% CI (0.40-0.84)) were also negatively associated with the willingness to get vaccinated against COVID-19. Remarkably, concerns such as the limited accessibility (aOR = 1.68, 95% CI (1.14-2.47)), and availability of vaccines (aOR = 2.16, 95% CI (1.46-3.20)) were associated with an increased likelihood of willingness to receive the COVID-19 vaccine. With regards to cues of action, receiving reliable and adequate information about the vaccine (aOR = 1.98, 95% CI (1.36-2.88)), recommendation by health authorities (aOR = 1.93, 95% CI(1.33-2.81)), and recommendations from health facilities (aOR = 2.68, 95% CI(1.80-3.99)) were also positively associated with vaccine acceptance. Lastly, perception of COVID-19 vaccine benefits by HCWs in terms of protecting them and their close contacts (patients, family members, and friends) from COVID-19 infection (aOR = 4.21, 95% CI (2.78-7.11)) was associated with an increased likelihood of vaccine uptake. The moderate acceptance rate of the COVID-19 vaccine among HCWs found in our study could have broader extents. Understanding and pointing out factors impairing vaccine acceptance such as concerns about the novelty of vaccine and manufacturers' reliability are required to reach a higher vaccination rate.

Knowledge, Attitudes, and Practices of Healthcare Workers in Jordan towards the COVID-19 Vaccination

The rapid development of COVID-19 vaccines raises concerns over vaccine hesitancy among healthcare workers (HCWs) and the general public, which made understanding the factors influencing hesitancy crucial in the maintenance of a solid healthcare system. This cross-sectional study investigated the knowledge, attitudes, and perceptions (KAP) of Jordanian HCWs to the COVID-19 vaccine from February to March 2021, using a self-administered questionnaire validated by a panel of public health experts. A total of 364 Jordanian HCWs were included in the final analysis, in which women accounted for 48.8% of the total sample. HCWs subjected to the seasonal flu vaccine were significantly more likely to uptake the COVID-19 vaccine. In comparison to nurses, physicians were significantly more likely to take or register for the vaccine. They demonstrated significantly higher knowledge of the vaccine’s effectiveness, side effect profile, recommended doses, and target population. Among our participants, the most common reasons for vaccine hesitancy include a lack of confidence, inadequate knowledge, and disbelief in effectiveness. Vaccine hesitancy among Jordanian HCWs is low, with discrepancies between nurses and physicians. It is pertinent for independent committees and trusted authorities to provide interventions and raise awareness regarding the vaccine’s safety and efficacy.

A multi-method analytical approach to predicting young adults' intention to invest in mHealth during the COVID-19 pandemic

Mobile-based health (mHealth) systems are proving to be a popular alternative to the traditional visits to healthcare providers. They can also be useful and effective in fighting the spread of infectious diseases, such as the COVID-19 pandemic. Even though young adults are the most prevalent mHealth user group, the relevant literature has overlooked their intention to invest in and use mHealth services. This study aims to investigate the predictors that influence young adults' intention to invest in mHealth (IINmH), particularly during the COVID-19 crisis, by designing a research methodology that incorporates both the health belief model (HBM) and the expectation-confirmation model (ECM). As an expansion of the integrated HBM-ECM model, this study proposes two additional predictors: mobile Internet speed and mobile Internet cost. A multi-method analytical approach, including partial least squares structural equation modelling (PLS-SEM), fuzzy-set qualitative comparative analysis (fsQCA), and machine learning (ML), was utilised together with a sample dataset of 558 respondents. The dataset-about young adults in Bangladesh with an experience of using mHealth-was obtained through a structured questionnaire to examine the complex causal relationships of the integrated model. The findings from PLS-SEM indicate that value-for-money, mobile Internet cost, health motivation, and confirmation of services all have a substantial impact on young adults' IINmH during the COVID-19 pandemic. At the same time, the fsQCA results indicate that a combination of predictors, instead of any individual predictor, had a significant impact on predicting IINmH. Among ML methods, the XGBoost classifier outperformed other classifiers in predicting the IINmH, which was then used to perform sensitivity analysis to determine the relevance of features. We expect this multi-method analytical approach to make a significant contribution to the mHealth domain as well as the broad information systems literature.

Determinants of COVID-19 Vaccine Acceptance among the Adult Population of Bangladesh Using the Health Belief Model and the Theory of Planned Behavior Model

Vaccination is undoubtedly one of the most effective strategies to halt the COVID-19 pandemic. The current study aimed to investigate the acceptance of COVID-19 vaccination and its associated factors using two health behavior change frameworks: the Health Belief Model (HBM) and the Theory of Planned Behavior (TPB). A total of 639 Bangladeshi adults (mean age: 24 years) participated in a cross-sectional online study between July and August 2021. The questionnaire covered questions regarding vaccine intentions, sociodemographic features, health status, perceived trust in/satisfaction with health authorities, reasons for vaccine hesitancy, and factors related to the health behavior change frameworks. Hierarchical logistic regression was employed to determine associations between these predictors and vaccine acceptance. The intention to get a COVID-19 vaccination was expressed among 85% of the participants. In fully adjusted models, students and respondents with more normal body weights reported higher intentions to get vaccinated. Respondents were also more likely to seek vaccination if they reported greater levels of perceived susceptibility, benefits, and cues to action, as well as lower levels of barriers and self-efficacy. Fear of future vaccine side effects was the most common reason for COVID-19 vaccine hesitancy and was expressed by 94% of the vaccine-hesitant respondents. These factors should be considered by health authorities in Bangladesh and perhaps other countries when addressing the plateauing COVID-19 vaccination rates in many populations.

Factors associated with Turkish pharmacists' intention to receive COVID-19 vaccine: an observational study

Background Pharmacists have been taking part in vaccination services during the COVID-19 pandemic. However, research identifying pharmacists’ intention to get COVID-19 vaccine is limited. Aim The objective of this study was to determine the intention to receive COVID-19 vaccine and to identify the factors related to it based on the Health Belief Model framework among Turkish pharmacists. Method This is an observational study conducted between December 2020 and January 2021. The online survey was sent to all hospital and community pharmacists working in Turkey. Transtheoretical Model of Behaviour Change and Health Belief Model were used for the development of the questionnaire. Univariate and multivariate logistic regression analyses were conducted to identify factors associated with the intention to receive COVID-19 vaccine. Results Among all participants (n = 961), 74.7% had an intention to receive the COVID-19 vaccine. In model 1, perceived susceptibility, perceived severity, perceived benefits, and perceived barriers were associated with their intention to receive the COVID-19 vaccine (p < 0.05). In model 2, the intention to receive COVID-19 vaccine was associated with being male, years of experience in the professional field, not having contracted COVID-19, having a pharmacy staff who had contracted COVID-19, and having had received seasonal flu shot within the previous year (p < 0.05). Conclusion This study highlights the factors related to the intention of the pharmacists to receive COVID-19 vaccines. Health Belief Model is the strongest predictor for vaccination intention and could be used to develop behavioural change techniques to promote vaccination.

A predictive model for identifying low medication adherence among older adults with hypertension: A classification and regression tree model

Various individual characteristics may affect medication adherence; however, few studies have investigated the effect of interrelationships among these various individual characteristics on medication adherence. This cross-sectional study explored the interrelationships among risk factors for medication adherence and established a predictive model of low medication adherence among older adults with hypertension. Convenience sampling was used to recruit 300 older adults with hypertension. The following parameters were recorded: demographic and disease characteristics, health beliefs, self-efficacy, social support, and medication adherence of antihypertensive drugs. Classification and regression tree (CART) analysis was performed to develop a predictive model of low medication adherence. The CART model revealed that health belief, disease duration, self-efficacy, and social support interacted to contribute to various pathways of low medication adherence. The predicted accuracy of the model was validated with a low misclassification rate of 26%. The proposed classification model can help identify risk cases with low medication adherence. Suitable health education programs based on these risk factors to manage and improve medication adherence for older adults with hypertension could be considered.

Health Belief Associated with Adherence to Health Protocol in Preventing Coronavirus Diseases on Patients’ Family

BACKGROUND: Adherence with health protocols during the Coronavirus disease (COVID-19) pandemic is very important to prevent transmission. However, it is obtained that adherence with health protocols is still not optimal. The hospital environment is an area that is at high risk of transmission. AIM: The purpose of this study is to analyze the relationship between health belief and adherence with the health protocol in the patient’s family. METHODS: Quantitative research is correlated with a cross-sectional approach. The sample is the family of patients at the hospital, which was taken with simple random sampling technique as many as 100 people. Research variables include perceived susceptibility, perceived severity, perceived benefits, perceived barrier, self-efficacy, and adherence with health protocols. Data collection was using questionnaire instruments. Data analysis was using Fisher test with a significance level of 95%. RESULTS AND DISCUSSION: Fisher’s test results obtained data that there is a relationship between health belief in the dimensions of perceived susceptibility (p = 0.007), perceived severity (p = 0.027), perceived benefits (p = 0.003), perceived barriers (p = 0.021), and self-efficacy (p = 0.002) with adherence with health protocols in an effort to prevent the transmission of COVID-19. The patient’s family will be willing to implement health protocols if they have a high health belief in efforts to prevent the transmission of COVID-19. This health belief includes the belief that COVID-19 disease is easily contagious and serious; adherence will provide benefits for health. CONCLUSION: Health beliefs are significantly related to adherence with health protocols in the prevention of COVID-19 transmission in the patient’s family.

Factors associated with COVID-19 vaccination intentions and attitudes in France

Objectives

The objective of the study is to investigate the factors associated with COVID-19 vaccination intentions and attitudes in France.

Study design

An online cross-sectional study was conducted among a representative sample of the French population between November 20th and 23rd 2020 (N = 1146).

Methods

Factors associated with the intention to get vaccinated and with COVID-19 vaccine attitudes were estimated using ordered logistic and multinomial logistic regressions, respectively. Independent variables of interest include COVID-19 and vaccine perceptions, trust, endorsement of COVID-19 conspiracy theories and time/risk preferences.

Results

Only 30.5% of our respondents would agree to get vaccinated against COVID-19 during the first semester of 2021 while 31.1% declare being unsure of their vaccination intentions. COVID-19 risk perceptions are associated with vaccination intentions and attitudes. Individual and collective benefits of the vaccine and the concerns over its safety are strongly associated with COVID-19 vaccination intentions and attitudes. Vaccine acceptors are more willing to take risks in the health domain compared with vaccine hesitant respondents which indicates that the COVID-19 vaccine is perceived as a greater health risk than the COVID-19 itself by some respondents. We also find a positive association between future preference and the willingness to get vaccinated.

Conclusion

Awareness campaigns should be conducted to enhance vaccination uptake among vaccine hesitant individuals. These campaigns could highlight the positive benefit-risk balance of the COVID-19 vaccines or the short-term benefits of vaccination and should reinsure the public on the safety of the COVID-19 vaccines.

Exploring the behavioral determinants of COVID-19 vaccine acceptance among an urban population in Bangladesh: Implications for behavior change interventions

BACKGROUND

While vaccines ensure individual protection against COVID-19 infection, delay in receipt or refusal of vaccines will have both individual and community impacts. The behavioral factors of vaccine hesitancy or refusal are a crucial dimension that need to be understood in order to design appropriate interventions. The aim of this study was to explore the behavioral determinants of COVID-19 vaccine acceptance and to provide recommendations to increase the acceptance and uptake of COVID-19 vaccines in Bangladesh.

METHODS

We employed a Barrier Analysis (BA) approach to examine twelve potential behavioral determinants (drawn from the Health Belief Model [HBM] and Theory of Reasoned Action [TRA]) of intended vaccine acceptance. We conducted 45 interviews with those who intended to take the vaccine (Acceptors) and another 45 interviews with those who did not have that intention (Non-acceptors). We performed data analysis to find statistically significant differences and to identify which beliefs were most highly associated with acceptance and non-acceptance with COVID-19 vaccines.

RESULTS

The behavioral determinants associated with COVID-19 vaccine acceptance in Dhaka included perceived social norms, perceived safety of COVID-19 vaccines and trust in them, perceived risk/susceptibility, perceived self-efficacy, perceived positive and negative consequences, perceived action efficacy, perceived severity of COVID-19, access, and perceived divine will. In line with the HBM, beliefs about the disease itself were highly predictive of vaccine acceptance, and some of the strongest statistically-significant (p<0.001) predictors of vaccine acceptance in this population are beliefs around both injunctive and descriptive social norms. Specifically, Acceptors were 3.2 times more likely to say they would be very likely to get a COVID-19 vaccine if a doctor or nurse recommended it, twice as likely to say that most people they know will get a vaccine, and 1.3 times more likely to say that most close family and friends will get a vaccine. The perceived safety of vaccines was found to be important since Non-acceptors were 1.8 times more likely to say that COVID-19 vaccines are "not safe at all". Beliefs about one's risk of getting COVID-19 disease and the severity of it were predictive of being a vaccine acceptor: Acceptors were 1.4 times more likely to say that it was very likely that someone in their household would get COVID-19, 1.3 times more likely to say that they were very concerned about getting COVID-19, and 1.3 times more likely to say that it would be very serious if someone in their household contracted COVID-19. Other responses of Acceptors on what makes immunization easier may be helpful in programming to boost acceptance, such as providing vaccination through government health facilities, schools, and kiosks, and having vaccinators maintain proper COVID-19 health and safety protocols.

CONCLUSION

An effective behavior change strategy for COVID-19 vaccines uptake will need to address multiple beliefs and behavioral determinants, reducing barriers and leveraging enablers identified in this study. National plans for promoting COVID-19 vaccination should address the barriers, enablers, and behavioral determinants found in this study in order to maximize the impact on COVID-19 vaccination acceptance.

University students' perspectives, planned uptake, and hesitancy regarding the COVID-19 vaccine: A multi-methods study

PURPOSE

To investigate university students' willingness to receive a COVID-19 vaccine when it becomes available to them.

METHOD

A multi-methods approach was used-online convenience sample surveys and semi-structured interviews-of young adults attending a large Canadian public university. Two survey samples were collected (June 20-July 28, 2020 and September 22-October 17, 2020). Semi-structured interviews were conducted following each survey, interviewing 20 students in each round.

RESULTS

In June 77.8% of surveyed students (n = 483) were willing to get the COVID-19 vaccine; in September 79.6% were willing (n = 1269). Multinomial and binary logistic regression analyses found that increasing perception of the severity of COVID-19 predicted the likelihood that a respondent was willing to get the COVID-19 vaccine in both surveys. In the latter survey students who indicated they would be encouraged to get the COVID-19 vaccine if their doctor/pharmacist recommended it were 76 times more likely to be willing to get the vaccine than those who would not be encouraged by medical advice. Interviews revealed concerns about the speed of the vaccine roll out, safety, and efficacy.

CONCLUSIONS

The majority of university students intend to get the COVID-19 vaccine, but there are nuanced concerns about efficacy and safety that must be taken into account by public health authorities as the vaccine becomes available to this group. Ensuring that family doctors, pharmacists, and other front-line healthcare workers have consistent and clear information regarding the benefits of vaccination will be critical to encouraging uptake among young adults.

COVID-19 vaccine hesitancy among health care workers in Palestine: A call for action

With the planned COVID-19 vaccine, vaccine hesitation is a great challenge, particularly for healthcare professionals. In this study, we examined the acceptance of the COVID-19 vaccine by health care workers, their concerns about it, and the reasons that might prevent them from getting vaccinated. We conducted a cross-sectional study using an anonymous online survey from December 25, 2020, to January 6, 2021. The questionnaire consisted of demographic characteristics (age, gender, profession, sector, medical history, and general health), COVID-19 related knowledge, and personal history of influenza vaccination. The intention to get the vaccine once it is available was directly asked, and attitudes towards the diseases and the vaccine were studied using a four-point Likert scale statement based on the health belief model's constructs. The study included 1159 HCWs; 62.9% were females, and 52.5% were between the ages of 30-49 years. The intention to get vaccinated was only 37.8% [95%CI: 35.0%-40.6%], while 31.5% were undecided, and 30.7% planned to refuse it. Higher levels of intention were reported among males (OR; 2.7, 95%CI: 2.0-3.7), younger ages (OR 1.7, 95%CI: 1.1-2.8), physicians (OR; 2.9, 95%CI: 2.0-4.0), HCWs at non-governmental settings (OR; 1.4, 95%CI: 1.1-1.9), those who previously received the influenza vaccine (OR 4.0, 95%CI: 2.3-7.1), and those who had higher COVID-19 related knowledge (OR; 1.7, 95%CI: 2.3-7.1). In conclusion, vaccine acceptance among HCWs was much lower than expected, which would greatly diminish the role of vaccination in reducing the burden of the COVID-19 pandemic throughout the community.

Health Belief Model in Hospitals: Determining the Effective Factors on Influenza Vaccination

: The need for extensive vaccination of health care workers (HCWs) is felt more than ever. The aim of this study was to investigate the determinants of influenza vaccination using HBM in HCWs of Jahrom hospitals. This cross-sectional study was performed by multicenter method on 614 HCWs in Jahrom, southern Iran, in 2020. Data collection tools included Demographic and researcher-made Influenza Vaccination in HCWs Based on HBM Questionnaires whose validity and reliability were measured and evaluated. Analyzes have been performed using SPSS 21. Increasing age (P < 0.001) and perceived barriers (P < 0.001) have increased influenza vaccination, but perceived benefits (P = 0.002), cues to action (P = 0.001), and self-efficacy (P < 0.001) have had a negative impact on influenza vaccination among HCWs. Perceived severity (P = 0.7) was higher in people with a history of influenza vaccination, while such a difference was not observed in perceived susceptibility. Higher mean age, previous vaccination history, and perceived barriers are predictors of influenza vaccine participation behavior.

Understanding the Influence of Individual and Systemic Factors on Vaccination Take-Up in European Citizens Aged 55 or Older

Background: High vaccination coverage provides extensive public health benefits. Hence, increasing vaccination rates is an important policy goal within the EU and worldwide. We aim to evaluate individual and systemic parameters associated with vaccination in European Union citizens aged 55 or older, using data from the Special Eurobarometer 488. Methods: Linear probability and probit models are estimated to analyze the determinants of vaccination take-up. Further, descriptive analyses are used to explore how the reasons for not having a vaccination differ by welfare regime. Results: High knowledge about the effectiveness and safety of vaccination increases the probability of receiving a vaccination during the past five years by 26 percentage points (pp), medium knowledge increases it by 15 pp. Focusing on the specific case of the flu, official recommendations increase this probability by, on average, 6 pp; while having to pay out-of-pocket for a recommended vaccination decreases it by, on average, 10 pp. Furthermore, the differences for no vaccination differ widely across welfare systems and television is the primary source for information about vaccination. Conclusions: Reported vaccination rates in Europe fall far below targets set by official recommendations. Increasing vaccination knowledge and offering vaccinations free of charge can help to increase vaccination rates. A specific focus should be put on reaching individuals with potential difficulties of access such as those living alone and unemployed.

Predictors of adherence with home quarantine during COVID-19 crisis: the case of health belief model

Although Jordan has applied lockdown in response to COVID-19 pandemic, many people were not adherent to the quarantine. We aimed to examine the attitudes of the Jordanians and how these attitudes can predict their adherence using the health belief model (HBM). A cross-sectional study of 5057 participants using an internet-based questionnaire was conducted during lockdown. Multivariable ordinal regression analyses were used to estimate predictors of adherence to home quarantine. Overall, 646 (12.8%), 2078 (41.2%), and 2317 (46%) of participants showed poor, intermediate, and strict adherence, respectively. Of the HBM constructs, seriousness (β= 0.116, 95% CI 0.027 to 0.205), benefits (β= 0.056, 95% CI 0.002 to 0.110) and barriers (β= -0.025, 95% CI -0.035 to -0.015) were significant predictors. We identified income insecurity (β= -0.096, 95% CI -0.144 to -0.046), social withdrawal (β= -0.062, 95% CI -0.121 to -0.004), religious concerns (β= -0.149, 95% CI -0.202 to -0.096) and health consequences (β= 0.065, 95% CI 0.011 to 0.11) as barriers. Governmental instructions were the only predictive external cue (β= 0.055, 95% CI 0.004 to 0.014). Our findings suggest that a high number of Jordanians are adherent with the quarantine, demonstrating the ability of governmental policies in tackling potential barriers.

Willingness to Receive Periodic Health Examination Based on the Health Belief Model Among the Elderly in Rural China: A Cross-Sectional Study

PURPOSE

This study aimed to explore factors affecting behavioral intention of receiving periodic health examinations (hereafter, BIE) among people aged 60 and over in rural China, namely, Shandong Province, using the extended health belief model (EHBM).

PATIENTS AND METHODS

Participants were selected using stratified multi-stage random sampling. Three cities were selected based on economic level. Subsequently, three counties and three villages were selected from each sample city and county. Finally, 30 respondents were selected from each sample village. Face-to-face surveys were conducted using a structured questionnaire between March and September 2017. Multiple linear regression was conducted to investigate the association between BIE and eight dimensions of EHBM: perceived susceptibility, perceived severity, perceived benefits, perceived barriers, perceived self-efficacy, cues to action, health knowledge, and social support.

RESULTS

Of the 509 rural respondents aged 60 years and older, the average score of behavioral intention was 4.43±0.80. Multivariate linear regression analysis demonstrated poor BIE among participants who were men, were current smoker, were current drinker, were aged 70 years or over, had lower social support, and perceived lower self-efficacy, less benefits, and more barriers. Among them, barriers were found to have the strongest association with BIE (B'=-0.556; p<0.001). Qualitative interviews revealed that reasons for not receiving periodic health examinations (PHE) included pain, cost, difficulty in finding a health care provider, time and scheduling, potential lack of trust in the physician, and value of the PHE.

CONCLUSION

This study highlighted the importance of psychological variables in the acceptance of PHE among the elderly in rural China and provided insights for further intervention designs targeting identified groups and performed by general practitioners. Addressing medical mistrust, strengthening, and enhancing one's social support network and health communication channels, such as bulletin boards, may serve to facilitate BIE.
