Reliability and validity of a survey to identify vaccine hesitancy among parents in Changxing county, Zhejiang province

Abstract

Background: To evaluate the validity and reliability of a survey to identify vaccine hesitancy among parents. Methods: Cross-sectional survey of parents of 19-35 month old children was conducted in Changxing County, Zhejiang Province, through a questionnaire developed for the survey of the vaccine hesitancy. Construct validity was assessed by linking parental responses to their child's immunization record. The association between mean% of days of under-immunization and the parental socio-demographics and the individual item response was explored via the univariate and multivariate analyses. Factor analysis was applied to confirm survey sub-domains and Cronbach's α to determine the internal consistency reliability of sub-domain scales. Results: We approached 336 households while 285 of them agreed to participate in this study. Education level and the parental 'score of vaccination hesitancy' were significantly associated with the mean% of days of under-immunization. Cronbach's coefficients for the 3 sub-domain scales created by regrouping the questionnaire's items were 0.71, 0.83, and 0.72, respectively. Conclusions: The survey represented a valid and reliable instrument to identify VHPs and it could help to screen parents to receive an intervention aimed at increasing acceptance of vaccinations.

Vaccine Hesitancy: COVID-19 and Influenza Vaccine Willingness among Parents in Wuxi, China—A Cross-Sectional Study

“…The type I error ( ) was 0.05, the precision ( d ) was 0.04, and the design effect (deff) was 2 [ 16 , 23 ]. A 50% vaccine hesitancy rate (to get the largest sample size) was used because this number was not given in the previous study.…”

“…In China, vaccine hesitancy needs attention: 24.9% of parents showed hesitancy to get all the recommended vaccinations for their child(ren) [ 16 ]. Meanwhile, the influenza vaccine is not regarded as important.…”

Indecisión a las vacunas: una revisión sistemática para abordar el fenómeno en Latinoamérica

“…Group agregando que es un fenómeno complejo y específico de un contexto que cambia con el tiempo, lugar y el tipo de vacuna. Los cuestionarios o escalas utilizadas que sufrieron modificación para su uso fueron: Parental Attitudes About Childhood Vaccines (PACV) n=12 (12,15,16,(18)(19)(20)(21)(22)25,27,29,30) Vaccine Hesitancy Scale (VHS) n= 5 (13,14,24,26,28) Survey of Vaccine Hesitancy n= 1 (17) y un estudio comparativo entre el PACV y Healt Styles Survey adoptadas del análisis de Gust et al (23) , n= 1.…”

“…El instrumento desarrollado en China, Survey of Vaccine Hesitancy tiene un total de quince ítems, agrupados en tres factores: "conductas" con alfa de Cronbach 0,71, "seguridad y eficacia" con 0,83, y "actitudes" con 0,72 (17) .…”

“…Las variables sociodemográficas de interés en los estudios fueron el género, edad, educación, ingresos económicos, número de hijos, edad de los hijos, empleo y estado civil. Otras variables de estudio fueron el estado de vacunación del hijo y si habían retrasado o rechazado alguna vez la administración de al menos una vacuna, la percepción de las EPV y ESAVI se emplearon de forma correlacional y predictiva, es decir si el resultado obtenido de los instrumentos puede tener efecto en el estado de vacunación del hijo y la probabilidad de que retrasen o rechacen en algún momento la administración de alguna vacuna (15,17,18,23,25,(27)(28)(29)(30) .…”
