Measuring psychosocial determinants of vaccination behavior in healthcare professionals: validation of the Pro-VC-Be short-form questionnaire

A systematic review of measures of healthcare workers' vaccine confidence

Healthcare workers (HCW) perceptions toward vaccines influence patient and community vaccine decision making. In an era of rising vaccine hesitancy, understanding HCW vaccine confidence is critical. This systematic review aims to review instruments that have been validated to measure HCW vaccine confidence. We conducted a search in five databases in June 2023. Data was descriptively synthesized. Twelve articles describing 10 different tools were included. Most tools included dimensions or items on vaccine knowledge (n = 9), safety (n = 8), vaccine usefulness (n = 8), recommendation behavior (n = 8), and self-vaccination practice (n = 7). All, except one study, were conducted in high-income countries. There was variability in the quality of the validation process. There is limited existing literature on development and validation of tools for HCW vaccine confidence. Based on the tools currently available, the Pro-VC-Be tool is the most well validated. Further research needs to include low- and middle-income contexts.

Motivational interview training improves self-efficacy of GP interns in vaccination consultations: A study using the Pro-VC-Be to measure vaccine confidence determinants

Immunization-specific motivational interviewing (MI), a patient-centered communication style used to encourage internal motivation for attitudinal and behavioral change, can provide healthcare professionals (HCPs) with the skills and practice required to respond to patients' doubts and concerns related to vaccines. We sought to assess the impact of an MI-training of General Practitioner (GP) interns on the psychosocial determinants of their vaccine confidence and behaviors. French GP interns participated in a virtual three-day MI-workshop in southeastern France. We used the validated Pro-VC-Be questionnaire - before and after the MI-workshop spanning over three months - to measure the evolution of these determinants. Scores before and after workshop trainings were compared in pairs. Participants' scores for commitment to vaccination (+10.5 ± 20.5, P = .001), perceived self-efficacy (+36.0 ± 25.8, P < .0001), openness to patients (+18.7 ± 17.0, P < .0001), and trust in authorities (+9.5 ± 17.2, P = 0.01) significantly increased after the training sessions, but not the score for confidence in vaccines (+1.5 ± 11.9, P = .14). The effect sizes of the four score improvements were moderate to large, with self-efficacy and openness to patients having the largest effect sizes (P = .83 and 0.78, respectively). This study provides evidence that certain determinants of overall vaccine confidence in HCPs, reflected respectively in the openness to patients and self-efficacy scores of the Pro-VC-Be, improve after immunization MI-training workshops. Incorporating immunization-specific MI-training in the curriculum for HCPs could improve several necessary skills to improve HCP-patient relationships and be useful for vaccination and other healthcare services.

Vaccine hesitancy among nursing and midwifery undergraduate students in Switzerland: protocol for an online national study

Background

Vaccine hesitancy is a persistent challenge in public health, exacerbated by the proliferation of anti-vaccine sentiments facilitated by social networks. The COVID-19 pandemic has underscored the importance of addressing vaccine hesitancy, designated by the WHO as a top global health threat. This study explores vaccine hesitancy among nursing and midwifery undergraduate students in Switzerland-a cohort crucial to public health given their future roles as healthcare professionals-with a particular emphasis on the HPV vaccine, which exhibits lower confidence levels compared to other vaccines.

Methods

This study will employ an online questionnaire distributed to nursing and midwifery undergraduate students from various healthcare universities. The questionnaire will collect data on vaccine hesitancy (general confidence in vaccines and specifically in the HPV vaccine), HPV vaccine coverage, socio-demographics, likelihood to recommend vaccines to patients, perception of vaccination education and interest in complementary medicine.

Conclusion

The study's findings will contribute to our understanding of vaccine hesitancy among nursing and midwifery undergraduate students, providing insights that can inform targeted interventions and education strategies to bolster vaccine confidence among future healthcare professionals, thereby enhancing public health efforts.

Pharmacists' approaches to vaccination consultations in Switzerland: a qualitative study comparing the roles of complementary and alternative medicine (CAM) and biomedicine

BACKGROUND

Many community pharmacies in Switzerland provide complementary and alternative medicine (CAM) approaches in addition to providing biomedical services, and a few pharmacies specialise in CAM. A common perception is that CAM providers are sceptical towards, or opposed to, vaccination.

OBJECTIVES

Key objectives of this study are to examine the potential roles of biomedically oriented and CAM-specialised pharmacists regarding vaccine counselling and to better understand the association between vaccine hesitancy and CAM.

DESIGN

We conducted semistructured, qualitative interviews. Transcripts were coded and analysed using thematic analysis. Interview questions were related to: type of pharmaceutical care practised, views on CAM and biomedicine, perspectives on vaccination, descriptions of vaccination consultations in community pharmacies and views on vaccination rates.

SETTING

Qualitative interviews in three language regions of Switzerland (German, French and Italian).

PARTICIPANTS

We interviewed 18 pharmacists (N=11 biomedically oriented, N=7 CAM specialised).

RESULTS

Pharmacist participants expressed generally positive attitudes towards vaccination. Biomedically oriented pharmacists mainly advised customers to follow official vaccination recommendations but rarely counselled vaccine-hesitant customers. CAM-specialised pharmacists were not as enthusiastic advocates of the Swiss vaccination recommendations as the biomedically oriented pharmacists we interviewed. Rather, they considered that each customer should receive individualised, nuanced vaccination advice so that customers can reach their own decisions. CAM-specialised pharmacists described how mothers in particular preferred getting a second opinion when they felt insufficiently advised by biomedically oriented paediatricians.

CONCLUSIONS

Vaccination counselling in community pharmacies represents an additional option to customers who have unmet vaccination consultation needs and who seek reassurance from healthcare professionals (HCPs) other than physicians. By providing individualised vaccination counselling to vaccine-hesitant customers, CAM-specialised pharmacists are likely meeting specific needs of vaccine-hesitant customers. As such, research and implementation efforts should more systematically involve pharmacists as important actors in vaccination provision. CAM-specialised pharmacists particularly should not be neglected as they are important HCPs who counsel vaccine-hesitant customers.

Healthcare professionals' attitudes to mandatory COVID-19 vaccination: Cross-sectional survey data from four European countries

Mandatory vaccinations are widely debated since they restrict individuals' autonomy in their health decisions. As healthcare professionals (HCPs) are a common target group of vaccine mandates, and also form a link between vaccination policies and the public, understanding their attitudes toward vaccine mandates is important. The present study investigated physicians' attitudes to COVID-19 vaccine mandates in four European countries: Finland, France, Germany, and Portugal. An electronic survey assessing attitudes to COVID-19 vaccine mandates and general vaccination attitudes (e.g. perceived vaccine safety, trust in health authorities, and openness to patients) was sent to physicians in the spring of 2022. A total of 2796 physicians responded. Across all countries, 78% of the physicians were in favor of COVID-19 vaccine mandates for HCPs, 49% favored COVID-19 vaccine mandates for the public, and 67% endorsed COVID-19 health passes. Notable differences were observed between countries, with attitudes to mandates found to be more positive in countries where the mandate, or similar mandates, were in effect. The associations between attitudes to mandates and general vaccination attitudes were mostly small to neglectable and differed between countries. Nevertheless, physicians with more positive mandate attitudes perceived vaccines as more beneficial (in Finland and France) and had greater trust in medical authorities (in France and Germany). The present study contributes to the body of research within social and behavioral sciences that support evidence-based vaccination policymaking.

International adaptation and validation of the Pro-VC-Be: measuring the psychosocial determinants of vaccine confidence in healthcare professionals in European countries

BACKGROUND

Healthcare professionals (HCPs) play an important role in vaccination; those with low confidence in vaccines are less likely to recommend them to their patients and to be vaccinated themselves. The study's purpose was to adapt and validate long- and short-form versions of the International Professionals' Vaccine Confidence and Behaviors (I-Pro-VC-Be) questionnaire to measure psychosocial determinants of HCPs' vaccine confidence and their associations with vaccination behaviors in European countries.

RESEARCH DESIGN AND METHODS

After the original French-language Pro-VC-Be was culturally adapted and translated, HCPs involved in vaccination (mainly GPs and pediatricians) across Germany, Finland, France, and Portugal completed a cross-sectional online survey in 2022. A 10-factor multigroup confirmatory factor analysis (MG-CFA) of the long-form (10 factors comprising 34 items) tested for measurement invariance across countries. Modified multiple Poisson regressions tested the criterion validity of both versions.

RESULTS

2,748 HCPs participated. The 10-factor structure fit was acceptable to good everywhere. The final MG-CFA model confirmed strong factorial invariance and showed very good fit. The long- and short-form I-Pro-VC-Be had good criterion validity with vaccination behaviors.

CONCLUSION

This study validates the I-Pro-VC-Be among HCPs in four European countries; including long- and short-form tools for use in research and public health.
