A Correlation Analysis between the Parent Attitudes about Childhood Vaccines Short Scale and the Vaccination Confidence Scale Open Access
Amobi, Chimora (Spring 2018)
Identifying vaccine-hesitant parents is important to deliver interventions that will boost vaccine acceptance and prevent progression to complete vaccine refusal. There is a need to identify an effective survey tool that can aid in classification of vaccine hesitancy among both parents of young children and parents of adolescents. The five-item Parental Attitudes about Childhood Vaccines (PACV) short scale is easier to administer, can be integrated into the clinical setting, and can be used for national surveillance but requires further testing and validation This analysis assessed the correlation between the PACV short scale and the Vaccination Confidence Scale.
By conducting a secondary analysis of baseline data collected for a Human Papillomavirus (HPV) vaccine uptake intervention trial, we assessed correlation using the Spearman correlation coefficient, the Cochran-Mantel-Haenszel statistic, and the Kappa coefficient. Logistic regression models were then developed to assess the associations between the PACV categories, the VCS categories and an outcome of the respondent’s intent to vaccinate their daughter against HPV.
1421 participants were included in the analysis. The PACV and VCS categories were strongly correlated with each other (Spearman correlation coefficient = 0.69, p <.0001), and the Cochran-Mantel-Haenszel test of association showed a significant relationship (CMH statistic = 797.81, df = 4, p <.0001). Both tools were also found to have similar associations with an intent to vaccinate against HPV, indicating similar abilities in classifying vaccine confidence.
The PACV short scale and VCS tools showed similar abilities in identifying and classifying vaccine-hesitant parents, as well as estimating intent to vaccinate against HPV among parents of female young children and adolescents. The PACV short scale is an effective tool. The VCS may be used effectively to assess vaccine confidence among parents of young children as well as parents of adolescents.
