“…The VAX-I also demonstrated satisfactory construct validity (H3 supported). The Italian VAX-I scale exhibited a negative and significant correlation with the general perception of health (GHP), and intention to get the flu vaccination– consistent with previous studies (Huza, 2020 ; Martin & Petrie, 2017 ), and trust in health authorities. Those with higher VAX-I scores also reported being more sensitive to medicines in general.…”

“…The results of the parallel factor analysis indicated that the Italian VAX-I scale has four distinct, but correlated factors confirming the original version of the VAX scale: (F1) mistrust of vaccine benefit, (F2) worries about unforeseen future effects, (F3) concerns about commercial profiteering, and (F4) preference for natural immunity. Furthermore, in line with the original study and the findings reported in previous translation and validation studies (Huza, 2020 ; Martin & Petrie, 2017 ; Yildiz et al, 2021 ), the confirmatory factor analysis indicated that the four-factor model provided the best fit to the current data (H1 was supported). In the present study, the results of the item-total correlation, Cronbach’s alpha, and McDonald’s omega coefficients indicated excellent internal consistency reliability of the VAX-I scale.…”

“…Recently, the VAX scale has been successfully validated in other languages, such as Romanian (Huza, 2020 ), Hebrew (Shacham et al, 2021 ), Spanish (Paredes et al, 2021 ), Turkish (Yildiz et al, 2021 ), and Telugu (Godasi et al, 2021 ). In addition, the VAX scale has also been adapted to specifically assess attitudes towards vaccines against COVID-19 (Shacham et al, 2021 ; Taylor et al, 2020 ).…”

Despite the massive volume of scientific evidence on the benefits of immunisation, vaccine hesitancy is still a global health threat and represents an obstacle to controlling the spread of viruses such as SARS-CoV-2 and its associated COVID-19. Thus, the present study aimed to adapt and validate an Italian version of the Vaccination Attitudes Examination (VAX) scale. The Italian version of the scale (VAX-I), along with validation measures (general health perceptions, perceived sensitivity to medicines, intention to get the flu vaccine, and trust in health authorities) were administered to a sample of 534 Italian participants aged 18 to 87 (M = 32.41, SD = 15.35). The original version of the VAX scale was translated into Italian using a back-translation method. The parallel and confirmatory factor analyses showed that the scale’s four-factor structure fits the data well, as in the original version. Reliability coefficients indicated that the VAX-I scale showed good internal consistency and measurement invariance results demonstrated that the VAX-I scale is stable across gender. Construct validity was supported by the significant negative correlation with general health perceptions, intentions to get the flu vaccine, and trust in health authorities, and the weak but significant and positive correlation with perceived sensitivity to medicines. Overall, the VAX-I scale appears to be a valid instrument to assess vaccine hesitancy in the Italian context.

“…The findings contribute to metrics which aim to assess vaccine hesitancy (Betsch et al, 2018;Huza, 2020;Martin & Petrie, 2017;Wood et al, 2019) through demonstrating that both the 5C and VAX are reliable and valid measures for use with an older adult (65+) population. Such measures can be used to inform targeted public health action to increase vaccine uptake with older adults, using appropriate strategies, policies, and interventions to reduce vaccine hesitancy (Frank et al, 2020;Jarrett et al, 2015;Nicholls et al, 2021).…”

Older adults are particularly vulnerable to vaccine-preventable diseases (VDU), due to decreased immunity and increased comorbidity. Vaccination can support healthy ageing and help reduce morbidity, mortality, and loss of quality of life associated with VPDs. Despite the availability of effective vaccines, many countries, including the UK, fail to reach recommended coverage levels. Psychosocial factors are recognised as providing important insights into the determinants of vaccination uptake. Little research has sought to establish psychometrically sound scales of vaccine attitudes with older adults. In the present study, a total of 372 UK-based participants (65-92 years, M = 70.5 yrs, SD = 4.6) completed a cross-sectional, online survey measuring health and socio-demographic characteristics in relation to vaccination uptake for influenza, pneumococcal and shingles. Two recently developed vaccination attitude scales, the 5C scale and the Vaccination Attitudes Examination (VAX) scale, were also administered to test their reliability and validity for use with an older adult population. Additional scales used to examine convergent and discriminant validity, the Beliefs about Medicines Questionnaire, the Perceived Sensitivity to Medicines Scale, the Medical Mistrust Index, the Perceived Stress Scale, and the Interpersonal Support Evaluation List, were included. The factor structure of the 5C and VAX scales was confirmed. Both scales showed good internal reliability, convergent, discriminant and concurrent validity, supporting their use with older adult populations. The 5C and VAX scales were found to be reliable and valid psychosocial measures of vaccine hesitancy and acceptance within a UK-based, older adult population. Future research could use these scales to evaluate the impact of psychological antecedents of vaccine uptake, and how concerns about vaccination may be understood and addressed among older adults.

“…The VAX scale has been translated and validated into several languages including Turkish [28] , Spanish [25] , and Romanian [29] . However, there is currently no French version of the VAX scale although French is the fifth most widely spoken language in the world.…”

Over the past decades, vaccination has proven to be largely beneficial to global health. Despite vaccine efficacy, the French population has been recently affected by more anti-vaccination attitudes and vaccine refusal, and it is therefore necessary to develop and validate tools to study this health issue. The Vaccination Attitudes Examination scale is a brief 12-item questionnaire targeting adults, that assesses general attitudes towards vaccination. The aims of the study were (1) to translate and adapt the original English version of the scale into French and (2) to test the psychometric properties of the scale in a French population-based sample of adults. We included 450 French speaking adults that completed the French Vaccination Attitudes Examination scale and other questionnaires in order to assess convergent and divergent validities. Exploratory and confirmatory factor analyses showed that the French version of the Vaccination Attitudes Examination scale replicated the factorial structure of the original scale. Moreover, it demonstrated high internal consistency, good convergent and divergent validities, and excellent temporal stability. Also, scores on the scale differentiated vaccinators from non-vaccinator respondents. Results on the scale provides us with insight into factors involved in vaccine hesitancy in France, therefore allowing French authorities and policy makers to address these specific concerns and by consequence improve vaccine acceptance rates in this country.
