Does the relative importance of MMR vaccine concerns differ by degree of parental vaccine hesitancy?: An exploratory study.

ABSTRACT:

Background

There has been a rise in the number of vaccine-hesitant parents (VHPs) in the US, many of whom express reservations about administering the MMR vaccine to their children. We studied the relative importance of attitudinal barriers to MMR vaccination among VHPs with differing levels of MMR vaccine-hesitancy.

Methods

We performed a cross-sectional exploratory analysis of a parental survey that assessed common vaccination barriers among MMR vaccine-hesitant parents in Michigan. The outcome of interest was parental MMR vaccination intention, measured on an 11-point scale, with higher numbers corresponding to greater intent. The relative importance of identified barriers to MMR vaccination was assessed across levels of vaccine hesitancy. Exploratory factor analysis was performed to identify underlying attitudinal constructs and assess if these constructs' importance varied depending on the degree of parental vaccine hesitancy.

Results

Our study population included 79 Michigan parents who initially screened positive for MMR vaccine-hesitancy. Within this sample, 47% of parents were unsure about their vaccination intentions and 20% expressed negative intentions, while a third (33%) of parents had positive vaccination intentions when further questioned. After grouping the barriers in our study into four underlying factors, parents with negative vaccination intentions had statistically significant higher factor score for the factor "risks versus benefits" and a statistically significant lower mean score for "vaccine importance," compared with parents with unsure or positive intentions.

Conclusions

In this exploratory study we found that vaccine-specific concerns have varying salience for parents based on their vaccination intention. Thus, future educational programs likely should tailor messages based on the degree of vaccine hesitancy expressed in their target populations in order to improve their overall effectiveness.

Project description:BACKGROUND:Human papillomavirus (HPV) vaccine hesitancy among parents contributes to low vaccination coverage in adolescents. To improve health care provider communication and vaccine recommendation practices with hesitant parents, it is important to understand how providers perceive parental HPV vaccine hesitancy. OBJECTIVE:This study aimed to characterize perceived reasons for parental HPV vaccine hesitancy and identify factors associated with perceived parental hesitancy among providers at community-based pediatric clinics. METHODS:In 2018, providers in 23 community-based pediatric clinics in Tennessee were invited to complete a Web-based baseline survey as part of a larger quality improvement study focused on HPV vaccine uptake. These survey data were used for a cross-sectional, secondary data analysis. Scale scores ranging from 0 to 100 were calculated for provider self-efficacy (confidence in ability to recommend HPV vaccine), provider outcome expectations (expectations that recommendation will influence parents' decisions), and perceived parental HPV vaccine hesitancy. Provider confidence in HPV vaccine safety and effectiveness were categorized as high versus low. Clinic-level exposures examined were clinic size and rural-urban location. Descriptive analyses were used to characterize perceived parental barriers by provider type. Mixed-effects linear regression models were fit taking one exposure variable at a time, whereas controlling for provider type, age, gender, and race to identify provider- and clinic-level factors associated with perceived parental barriers to HPV vaccination. RESULTS:Of the 187 providers located in the 23 clinics, 137 completed the survey. The majority of physician providers were white and female, with a higher percentage of females among nurse practitioners (NPs) and physician assistants (PAs). The most common parental barriers to HPV vaccination perceived by providers were concerns about HPV vaccine safety (88%), child being too young (78%), low risk of HPV infection for child through sexual activity (70%), and mistrust in vaccines (59%). In adjusted mixed models, perceived parental HPV vaccine hesitancy was significantly associated with several provider-level factors: self-efficacy (P=.001), outcome expectations (P<.001), and confidence in HPV vaccine safety (P=.009). No significant associations were observed between perceived parental HPV vaccine hesitancy and clinic-level factors clinic size nor location. CONCLUSIONS:Researchers developing provider-focused interventions to reduce parental HPV vaccine hesitancy should consider addressing providers' self-efficacy, outcome expectations, and confidence in HPV vaccine safety to help providers communicate more effectively with HPV vaccine hesitant parents.
