Perspectives on decision making about human papillomavirus vaccination among 11- to 12-year-old girls and their mothers

Opportunities for HPV vaccine education in school-based immunization programs in British Columbia, Canada: A qualitative study

Despite the availability of school-based immunization programs (SBIPs) in Canada, human papillomavirus (HPV) vaccine uptake remains suboptimal. Vaccine education may improve vaccine uptake among adolescents. The objective of this qualitative study was to identify opportunities for HPV vaccine education in British Columbia, Canada, by exploring the perspectives of students, parents, school staff, and public health nurses on the current SBIP. Individual semi-structured interviews were conducted with adult participants and focus groups were conducted with grade 6 students between November 2019 and May 2020. The interviews and focus groups were transcribed and then analyzed using reflexive thematic analysis. Opportunities for HPV vaccine education were identified in three themes: 1) making SBIPs student-centered; 2) adopting a collaborative and interdisciplinary approach to vaccine education; and 3) actualizing parent education opportunities. Broad support existed for a formal, collaborative HPV grade 6 vaccine curriculum delivered by teachers and public health nurses to provide evidence-based health information. Participants voiced that the curriculum should integrate students' perspectives on topics of interest and address needle associated pain and anxiety. Parents were identified as the primary vaccine decisionmakers, therefore, participants stated it was crucial to also provide parent-directed vaccine education as part of SBIP. Our findings support the development of a collaborative HPV vaccine curriculum directed to and informed by students and parents to buttress current SBIPs in British Columbia.

A scoping review of the use of parent-adolescent dyads in HPV vaccination research

OBJECTIVE

Parental vaccine hesitancy is a significant contributor to low adolescent HPV vaccination. Shared HPV vaccination decision-making among adolescents and parents is an important determinant of vaccination uptake. We performed a scoping review to identify studies that used parent-adolescent dyads in HPV vaccination research.

METHODS

We searched peer-reviewed articles in PubMed, Embase, and PsychInfo from 2012 to 2023. Randomized or observational studies with parent-adolescent dyads related to HPV vaccination were eligible for inclusion. Articles were coded for the main themes related to use of parent-adolescent dyads in HPV vaccination research.

RESULTS

Fifteen articles met the inclusion criteria and were categorized into two main themes: qualitative decision-making and quantitative vaccination intentions. Dyad members reported substantially different roles, barriers, and facilitators of HPV vaccine decisions and intentions. Dyad members disagreed on who made the final decision. Provider recommendation style and content were important to parental confidence in the vaccine decision.

CONCLUSION

The recent evidence for parent-adolescent HPV vaccination dyad research is sparse but indicates that factors that account for dyad vaccination decisions and intentions often differ between dyad members.

PRACTICE IMPLICATIONS

Studies in this review support ongoing research with parent-adolescent dyads to target HPV vaccine interventions at individual dyad members to increase HPV vaccination.

Parents' COVID-19, HPV, and Monkeypox vaccination intention: A multilevel structural equation model of risk, benefit, barrier, and efficacy perceptions and individual characteristics

OBJECTIVE

This study seeks to comparatively examine parents' intention to vaccinate their children for three infectious diseases, including COVID-19, HPV, and monkeypox.

METHODS

Utilizing a mixed-design survey and multilevel structural equation models, we investigated if perception of the diseases and vaccines explained the variance in parents' vaccine-specific decision-making and population difference in vaccination intention.

RESULTS

Compared with the COVID-19 vaccine, parents were more willing to get an HPV vaccine for their children due to greater perceived benefit and lower perceived barrier. Concerns about vaccine safety and lower disease risk perception were associated with lower intention to get a monkeypox vaccine. Parents of color, less educated, and lower-income parents were less willing to get vaccines for their children due to low benefit perception and high perceived barriers.

CONCLUSION

Parents were motivated by different social and psychological factors when deciding whether to get a COVID-19, HPV, and monkeypox vaccine for their children.

PRACTICE IMPLICATIONS

Vaccine promotion should be tailored to the characteristics of the target population and the vaccines. Underprivileged communities may be better approached with information about vaccine benefit and barriers, and vaccines for unfamiliar diseases may be better communicated with disease risk information.

School Health Service Provider Perceptions on Facilitated Interactive Role-Play Around HPV Vaccine Recommendation

The purpose of this study was to evaluate a facilitated interactive role-playing activity on increasing human papillomavirus (HPV) vaccine recommendation skills for school nurses and school-based health center staff. A 1-day workshop was implemented for school-based clinicians focused on improving HPV vaccination rates in schools. The workshop included a facilitated interactive role-playing activity involving five scenarios related to recommending the HPV vaccine to parents. Participants completed a usability survey with open-ended questions assessing their experience. A general inductive approach was used to examine responses. Sixteen participants completed the usability survey. The major strength identified specific to the activity included opportunity to practice evidence-based recommendation skills (n = 10). Weaknesses of the activity identified included lack of diversity (n = 4) and complexity within the scenarios (n = 2). Results could shift current educational and clinical paradigms through the implementation of hands-on education strategies to effectively train school-based clinicians to strongly recommend the HPV vaccine.

Assessing the Level of Knowledge, Beliefs and Acceptance of HPV Vaccine: A Cross-Sectional Study in Romania

(1) Background: The infection with Human papilloma virus (HPV) is the most common sexually transmitted infection and it has been associated with cervical cancer (CC) in 99.7% of the cases. In Romania, CC is the second most common, with incidence (22.6%₀₀₀) and mortality rates (9.6%₀₀₀) three times higher than any other European country. Our aim was to assess the level of knowledge regarding HPV infection among parents, highschool students, medical students and doctors, with an emphasis on their main source of information—the Internet. (2) Methods: We applied five questionnaires to six categories of respondents: parents of pupils in the 6th–8th grades, medical students, doctors, boys in the 11th–12th grades, girls in the 11th–12th grades and their mothers. (3) Results: We included a total of 3108 respondents. 83.83% of all respondents had known about HPV infection. The level of information about HPV infection and vaccination was either satisfactory, poor or very poor. Their main source of information varied depending on the respondent profile and professional activity. Medical students were informed by doctors and healthcare professionals (53.0%), doctors gathered their information from books, journals and specialized brochures (61.6%). For the other categories of respondents, the Internet was the main source of information. Most respondents answered that doctors and healthcare professionals should provide information on HPV infection and vaccination, but very few of them actually seeked information from their general practitioner. (4) Conclusions: Population adherence to the appropriate preventative programs, as well as relevant information disseminated by the medical staff are key elements towards reducing the risk of HPV-associated cancers. An important role could also be played by schools, where teachers and school doctors could provide relevant information on the general aspects of HPV infection. Additionally, sex education classes and parent-teacher meetings should cover the main characteristics of HPV infection and what preventative measures can be employed against it.

HPV vaccination and cervical screening: the knowledge and attitudes of mothers of adolescent girls

OBJECTIVE

Mothers play a significant role in decision making about human papillomavirus (HPV) vaccination for their daughters and about cervical screening attendance for themselves. This study had three objectives, to explore: (1) mothers' knowledge and attitudes about HPV and HPV vaccination, (2) their knowledge and attitudes about cervical cancer and screening, and (3) whether their daughter's HPV vaccination invitation was an opportunity to nudge mothers to attend screening.

DESIGN

138 women from North Staffordshire completed a cross-sectional survey and 15 took part in follow-up focus groups.

RESULTS

Despite high self-reported engagement with both the cervical screening and HPV vaccination programmes, relatively low levels of knowledge and some uncertainty were evident. There was mixed opinion about the potential of using the vaccination invite as an opportunity to nudge mothers to attend cervical screening.

CONCLUSION

Even amongst women who do engage positively with the programmes, knowledge is not as complete and certain as it could be. Further research is needed with women who are less likely to accept the vaccination for their daughters. Women need to be better informed, which may go some way to reversing the decline in screening and maintaining high levels of vaccination.

Psychosocial and organizational barriers and facilitators of meningococcal vaccination (MenACWY) acceptance among adolescents and parents during the Covid-19 pandemic: a cross-sectional survey

BACKGROUND

This study aimed to identify differences and similarities among adolescents and parents in various psychosocial factors influencing meningococcal ACWY (MenACWY) vaccination acceptance. Besides, the impact of the Covid-19 pandemic was assessed as well as resulting organizational adjustments.

METHODS

We conducted a cross-sectional survey among adolescents that attended the appointment for the MenACWY vaccination in South Limburg between May and June 2020, and their parents. Independent t-tests and χ² test were performed to explore differences in psychosocial and organisational factors between adolescents and parents.

RESULTS

In total, 592 adolescents (20%) and 1197 parents (38%) filled out the questionnaire. Adolescents scored lower on anticipated negative affect towards MenACWY vaccination refusal [t (985.688) = - 9.32; ρ < 0.001], moral norm towards MenACWY vaccination acceptance [t (942.079) = - 10.38; ρ < 0.001] and knowledge about the MenACWY vaccination and meningococcal disease [t (1059.710) = - 11.24; ρ < 0.001]. Both adolescents and parents reported a social norm favouring accepting childhood vaccinations, but adolescent scored higher [t (1122.846) = 23.10; ρ < 0.001]. The Covid-19 pandemic did barely influence the decision to accept the MenACWY vaccination. Only 6% of the participants indicated that Covid-19 influenced their decision. In addition, the individual vaccination appointment was rated very positive. Most adolescents (71.5%) and parents (80.6%) prefer future vaccinations to be offered individually rather than having mass vaccinations sessions.

CONCLUSIONS

This study provides an indication of which psychosocial and organisational factors should be addressed in future MenACWY vaccination campaigns. Individual vaccination appointments for adolescents should be considered, taking the costs and logistical barriers into account.

What do adolescents think about vaccines? Systematic review of qualitative studies

Adolescence presents a key opportunity to build vaccine-related health literacy and promote vaccine confidence and uptake. Although adolescents are central to vaccination programs, their views around vaccines are frequently underrepresented in qualitative literature. We reviewed qualitative studies to systematically identify and summarize existing evidence on adolescents' own understanding of vaccines and experiences with vaccine decision-making, including self-consent when applicable. CINAHL; Embase; Ovid Medline; and Psych Info database searches were last updated on May 28, 2022. Data pertaining to general study characteristics, participant demographics, and qualitative content were extracted independently by two reviewers and analyzed using textual narrative synthesis. Out of 3559 individual records, 59 studies were included. The majority of the studies were conducted in high-income countries and 75% focused on human papilloma virus vaccines, with the remaining studies looking at COVID-19, meningococcal, hepatitis B and influenza vaccines or adolescent experiences with vaccines in general. Adolescent self-consent was explored in 7 studies. Perspectives from sexual and gender minorities were lacking across studies. Adolescents often had limited understanding of different vaccines and commonly perceived vaccine information to be directed towards their parents rather than themselves. Many adolescents felt school-based vaccine education and information available through healthcare providers were insufficient to make informed decisions about vaccines. While adolescents described obtaining vaccine information from traditional and online media, face-to-face interactions and opinions from trusted adults remained important. Adolescents generally relied on their parents for vaccine-decision making, even when self-consent was an option. A notable exception to this included marginalized adolescents who could not rely on parents for health-related advice. Qualitative literature about adolescent vaccines would be enriched by studies examining vaccines other than the HPV vaccine, studies examining adolescent vaccine programs in low and middle-income countries, and by deliberately eliciting vaccine experiences of adolescent with diverse sexual orientation and gender identities.

Effect of a School-Based Educational Intervention About the Human Papillomavirus Vaccine on Psychosocial Outcomes Among Adolescents: Analysis of Secondary Outcomes of a Cluster Randomized Trial

IMPORTANCE

Delivery of vaccination to adolescents via a school-based program provides an opportunity to promote their involvement in health decision-making, service provision, and self-efficacy (belief in one's ability to perform a certain behavior).

OBJECTIVE

To examine the effect of a human papillomavirus (HPV) vaccination education and logistical intervention on adolescent psychosocial outcomes.

DESIGN, SETTING, AND PARTICIPANTS

In this cluster randomized trial and process and qualitative evaluation, adolescents aged 12 to 13 years (first year of high school) were recruited at high schools in Western Australia (WA) and South Australia (SA) in 2013 and 2014. Statistical analysis was performed from January 2016 to December 2020.

INTERVENTIONS

The complex intervention consisted of an adolescent intervention to promote knowledge and psychosocial outcomes, shared decisional support tool, and logistical strategies.

MAIN OUTCOMES AND MEASURES

Prespecified secondary outcomes were assessed. The HPV Adolescent Vaccination Intervention Questionnaire (HAVIQ) was used to measure changes in adolescent knowledge (6-item subscale), fear and anxiety (6-item subscale), self-efficacy (5-item subscale), and decision-making (8-item subscale). The hypothesis was that the intervention would improve adolescent involvement in vaccine decision-making (measured before dose 1 only), improve vaccine-related self-efficacy, and reduce vaccine-related fear and anxiety (measured before doses 1, 2, and 3). Mean (SD) scores for each subscale were compared between intervention and control students. In the process evaluation, focus groups were conducted. Analyses of the HAVIQ data were conducted from 2016 to 2020. Qualitative analyses of the focus groups were undertaken from 2017 to 2020.

RESULTS

The trial included 40 schools (21 intervention and 19 control) across sectors with 6967 adolescents (mean [SD] age, 13.70 [0.45] years). There were 3805 students (1689 girls and 2116 boys) in the intervention group and 3162 students (1471 girls and 1691 boys) in the control group. The overall response rate for the HAVIQ was 55%. In WA, where parental consent was required, the response rate was 35% (1676 of 4751 students); in SA, where parental consent was not required, it was 97% (2166 of 2216 students). The mean (SD) score for decision-making in the intervention group before dose 1 was 3.50 (0.42) of 5 points and 3.40 (0.40) in the control group, a small but significant difference of 0.11 point (95% CI, 0.06 to 0.16 point; P < .001). There was a small difference in favor of the intervention group in reduced vaccination-related anxiety (pre-dose 1 difference, -0.11 point [95% CI, -0.19 to -0.02 point]; pre-dose 2 difference, -0.18 point [95% CI, -0.26 to -0.10 point]; pre-dose 3 difference, -0.18 [95% CI, -0.24 to -0.11]) and increased vaccination self-efficacy (pre-dose 1 difference, 4.0 points; [95% CI, 1.0 to 7.0 points]; pre-dose 2 difference, 4.0 points [95% CI, 2.0 to 6.0 points]; pre-dose 3 difference, 3.0 points [95% CI, 1.0 to 5.0 points]). Focus group data from 111 adolescents in 6 intervention and 5 control schools revealed more confidence and less anxiety with each vaccine dose.

CONCLUSIONS AND RELEVANCE

In this cluster randomized trial, there was a small difference in adolescent decisional involvement and vaccine-related confidence and reduced vaccination-related fear and anxiety that was maintained throughout the vaccine course in the intervention vs control groups. Guidelines for vaccination at school should incorporate advice regarding how this outcome can be achieved.

Multistakeholder knowledge levels and perspectives of human papillomavirus and its vaccination: An exploratory qualitative study

OBJECTIVE

This qualitative study was an integral part in the development of a multidisciplinary team-led school-based human papillomavirus vaccination health-promotion programme (MDL-SHPVP) aiming to increase HPV vaccine uptake in Hong Kong. Study findings will inform the design of the MDL-SHPVP by drawing on interview data regarding the expectations and needs of key stakeholders and potential programme users.

METHODS

Eight mother-daughter dyads, four secondary school teachers, two school principals, three social workers and one school nurse were interviewed. All interviews were audio-recorded and transcribed verbatim for thematic analysis.

RESULTS

Most participants had misconceptions about HPV and the vaccine. Alhough there was no immediate perceived need for the vaccination, most participants had favourable attitudes towards HPV inoculation and vaccines in general. Factors affecting vaccine uptake included perceptions about risk of infection, vaccine availability, and cost. Participants were largely open to suggested MDL-SHPVP components (videos, digital game, and group discussions).

CONCLUSION

Findings have highlighted knowledge gaps among potential users and key stakeholders and will be used to inform the design of the MDL-SHPVP to ensure that their needs and expectations are addressed. Study findings may also aid future HPV vaccine promotion efforts and boost HPV vaccine uptake among youth in the city.

Race, Nativity, and Sex Disparities in Human Papillomavirus Vaccination Among Young Adults in the USA

Research has demonstrated that the human papillomavirus (HPV) vaccine is a safe and effective way to decrease HPV-related cervical cancers; however, the vaccination rate in the USA is suboptimal. The current study examined racial and ethnic disparities in HPV vaccination among a nationally representative sample, including Native Hawaiian and Pacific Islanders (NHPI). This study also investigated the associations between nativity and vaccination, and sex differences between race/ethnicity and vaccination and nativity and vaccination. A cross-sectional study was conducted with a sample of adults aged 18-26 years drawn from the 2014 NHPI National Health Interview Survey (n = 2590) and the general 2014 National Health Interview Survey (n = 36,697). Log-binomial models were fitted to examine differences in vaccination. There was a statistically significant racial/ethnic difference in HPV vaccination (p = 0.003). More women than men were vaccinated (41.8% vs. 10.1%) (p < 0.001). There was a significant difference in HPV vaccination based on nativity: 27.4% of adults aged 18 to 26 years who were born in the USA and 27.7% born in a US territory received the HPV vaccine compared with 14.3% among those not born in the USA or a US territory (p < 0.001). The association of HPV vaccination with nativity and race/ethnicity differed by sex and showed several nuanced differences. Overall, the prevalence of HPV vaccination was low. The study's findings demonstrate the need for public health strategies to increase vaccination rates among all populations, with the critical need to identify strategies that are effective for men, racial/ethnic minorities, and immigrant women born outside the USA.

The role of maturity in adolescent decision-making around HPV vaccination in France

Mothers are often responsible for vaccination decisions in the household. However, their confidence in certain vaccines such as Human Papillomavirus (HPV) vaccines is eroding in some countries. France is one of the countries with the lowest HPV vaccine uptake in Europe, with parents delaying or refusing the vaccine for their adolescent daughters due to safety- and effectiveness-related concerns. Although parental consent is required for vaccination, adolescents' involvement in HPV vaccination decision-making could improve vaccine uptake, with self-consent procedures already introduced in some countries. Adolescents' capacity to engage in decision-making is influenced by their maturity and autonomy in health. This study explored the role of maturity in decision-making around HPV vaccination in France through qualitative interviews with adolescent girls (n = 24) and their mothers (n = 21) and two focus groups with adolescent girls (n = 12). A codebook approach to thematic analysis revealed that adolescent girls' involvement in HPV decision-making is a process that evolved with maturity. As adolescents progressed towards maturity at different speeds, some expressed childlike traits such as impulsive decisions and others described more rational, reflective decision-making. Despite these differences, most adolescents in this study described a passive role in HPV vaccination decision-making, following their parents' lead. However, their expressed desire for information and involvement in discussions indicates that their lack of engagement may not only be due to a lack of maturity but also a result of mothers and doctors excluding them from getting involved. Furthermore, as health behaviours are shaped during adolescence, the influence of vaccine hesitant mothers on their daughters' own views and beliefs could be significant, together with exposure to regular controversies in the mainstream media. Individualised approaches to engage adolescents in decision-making around their own health are needed, for example through strengthening discussions and information around HPV vaccination with parents and doctors.

Factors Associated With African American Mothers' Perceptions of Human Papillomavirus Vaccination of Their Daughters: An Integrated Literature Review

PROBLEM IDENTIFICATION

African American (AA) women have a higher mortality rate for cervical and other cancers and are less likely to have received the human papillomavirus (HPV) vaccine than White women. Mothers play a significant family role and have a unique relationship with their daughters. Mothers' positive views on HPV vaccination may enhance the HPV vaccination rate among their daughters.

LITERATURE SEARCH

The review was conducted by searching literature in PubMed®, CINAHL®, ScienceDirect, Ovid MEDLINE®, and ProQuest databases. The search was limited to studies conducted in the United States and published since the inception of the HPV vaccine in 2006.

DATA EVALUATION

Of 10,566 publications retrieved, 28 articles were included in the final sample.

SYNTHESIS

Factors associated with HPV vaccination were approval and disapproval of HPV vaccination from physicians, family, and friends; HPV knowledge; attitude and belief about HPV vaccination; benefits of vaccination; and challenges of and barriers to HPV vaccination.

IMPLICATIONS FOR PRACTICE

Understanding factors related to HPV vaccination decisions among AA mothers will inform healthcare providers of the best approach to improving vaccination rates among this high-risk population.

From knowledge to a gendered event and trustful ties: HPV vaccine framings of eligible Finnish girls and school nurses

In the present study, we examine socio-cultural and practical aspects of human papillomavirus vaccination (HPVV) through a multi-sited study of framings. We ask how HPVV is framed in the daily lives of vaccination-aged Finnish girls and in school nurses' everyday work. We then mirror these framings against both each other and Finland's official vaccination campaign. Based on analysis of interviews with 24 nurses and 12 girls and the campaign materials, we argue first that the campaign frames vaccination as an individual, knowledge-based decision reflecting the informed consent principle. Second, however, the vaccination is framed in the everyday lives of eligible girls through gendered social ties and as a gendered and cohort-specific event pivoting around the needle prick. Third, HPVV is not primarily framed in the school nurses' work as preparing the girls for the vaccination decision by sharing official information but through trust-based social relationships with the girls and their parents. We conclude that, as the vaccination is not an issue of individually reflected and knowledge-based decision-making for the two interviewed key groups, the official Finnish HPVV campaign and the undergirding informed consent principle drift into problems in their practical implementation.

Who knows best? Health risks and digital media engagement in Discourses relating to human papillomavirus vaccination

In Denmark, parents have needed to deal with inconsistent presentations of risk regarding the human papillomavirus (HPV) vaccination. This has complicated the parents' task of making a decision about having their daughters vaccinated. In this article, I analyse how Danish parents engage with digital media when making this decision. The results are based on interviews with 18 Danish parents of girls aged 10-13 years old. In my analysis of the interviews, I found that parents align with one of two Discourses when engaging with digital media in relation to HPV vaccination: one centralised and one decentralised. In the centralised Discourse, parents leave it up to other actors such as health authorities to manage the risks of vaccination, thus limiting the experienced need to engage with digital media; in the decentralised Discourse, however, parents themselves assess potential risks, thereby increasing the need to engage with digital media. As a result, I discuss why some parents can consider it necessary to struggle to engage in literacies when making decisions about complex health topics, even when there are clear government recommendations.

Human papillomavirus vaccination uptake: a longitudinal study showing ethnic differences in the influence of the intention-to-vaccinate among parent-daughter dyads

INTRODUCTION

It is unclear what role daughters play in the decision-making process regarding HPV vaccination. Therefore, we explored the impact of HPV vaccination intention among parents and their 12-13 year-old daughters on HPV vaccination uptake.

METHODS

In February 2014 parents/guardians and their 12-13 year-old daughters were invited to complete a questionnaire about socio-psychological determinants of the decision-making process regarding HPV vaccination. Vaccination status of the daughter was retrieved from the national vaccination database after the last possible vaccination date in 2014. The association between HPV vaccination uptake and intention, and determinants of intention, was jointly assessed using a generalized structural equation model, stratified by origin of parents (Dutch versus non-Dutch).

RESULTS

In total, 273 Dutch parent-daughter dyads and 165 non-Dutch dyads were analyzed for this study. HPV vaccination uptake was 90% (246/273) and 84% (139/165) in the Dutch and non-Dutch group, respectively. In the Dutch group, high parental intention (β = 2.3, 95%CI 1.2-3.3) and high daughters' intention (β = 1.5, 95%CI 0.41-2.6) were significantly associated with HPV vaccination uptake. In the non-Dutch group, high daughters' intention (β = 1.2, 95%CI 0.16-2.2) was significantly associated with HPV vaccination, but high parental intention was not (β = 0.52, 95%CI -0.47-1.5). Attitude was the most prominent socio-psychological determinant associated with vaccination intention among all groups.

CONCLUSION

In the non-Dutch group, only daughters' intention was significantly associated with HPV vaccination uptake, whereas in the Dutch group both the parents' and the daughters' intention were significantly associated with uptake. The role of the child in the decision-making process might need to be taken into account when developing new interventions focused on increasing HPV vaccination uptake, especially among individuals of non-Dutch origin.

Understanding How Adolescents Think about the HPV Vaccine

Despite educational efforts, Tennessee human papillomavirus (HPV) vaccination rates are 43%, among the lowest in the United States. This study examined how adolescents think about the HPV vaccine to identify patterns and misconceptions to enhance educational efforts. Adolescents (ages 11–12) (N = 168) responded to open-ended questions regarding their thinking about the HPV vaccine. Data were analyzed and interpreted using qualitative thematic analysis. Three domains of themes emerged from responses: (1) characteristics of HPV vaccination, (2) knowledge-related themes, and (3) beliefs-related themes. Prevention of HPV and cancer was the most referenced characteristic of HPV vaccination followed by HPV vaccine rates and HPV vaccine efficacy. Student inquiries were mostly centered on HPV vaccine composition, administration, duration and how the vaccine interacts with the body. Some responses indicated a desire for more information about HPV not specific to the HPV vaccine. Overall, adolescent attitudes were positive towards the HPV vaccine. This study highlights specific questions adolescents have about the vaccine that can be used to tailor future HPV educational efforts, empowering adolescents with the knowledge to be more active students in the decision-making process. In addition, the potential for adolescents to serve as community advocates for the vaccine should be considered for future interventions.

Calling the Shots? Adolescents' Influence on Human Papillomavirus Vaccine Decision-Making During Clinical Encounters

PURPOSE

The aim of the study was to examine adolescents' influence on human papillomavirus (HPV) vaccine decision-making and receipt during clinical visits.

METHODS

We recruited English- and/or Spanish-speaking parents and their adolescent children aged 9-17 years who were eligible for the first HPV vaccine dose and seeking routine care at pediatric and family medicine clinics in the Greater Boston area enrolled in a multilevel intervention to improve HPV vaccination coverage. Parents completed previsit surveys that included parental intention to vaccinate. We coded transcripts of adolescents' clinical encounters to define adolescents' participation in vaccine discussions and cooperation with immunization. Adolescents' influence on vaccine decision-making was determined based on analyses of their participation in discussions and parents' previsit vaccine intentions.

RESULTS

A total of 113 adolescents and their parents participated. Eighty-seven percent of adolescents received their first HPV vaccine dose during the visit. Most reactions were negative (23% mild, 23% moderate, and 10% extreme); nearly all objections were concerns related to the pain of injection rather than specific to HPV vaccination. A minority of reactions were positive (12%), 33% were neutral, and 12% did not participate in vaccine discussions. All adolescents with positive or neutral reactions received vaccination, as did 91% of those with negative reactions. After accounting for parents' previsit vaccine intentions and analyzing discussions during clinical encounters, only 5% of adolescents appeared to influence vaccination either positively (n = 3) or negatively (n = 3).

CONCLUSIONS

In this study, adolescents rarely influenced parents' vaccine decision-making, although many exhibited distress over the pain of injections. This suggests that increasing adolescents' involvement in vaccine discussions may have limited effects on vaccination rates.

Relationship between Mothers&apos; Diagnosis of Cervical Cancer and Attitudes toward Preventing Cervical Cancer in Their Pubertal Daughters

PURPOSE

This study was conducted to examine the relationship between a mother's diagnosis of cervical cancer and attitudes toward cervical cancer prevention in their daughters. Their intention to recommend human papillomavirus (HPV) vaccination for their daughters, their confidence in 8 methods for cervical cancer prevention with their daughters, and their negative emotions about the assumption of their daughter's HPV infection.

METHODS

This study was a secondary analysis of data from the study of maternal health beliefs about preventing cervical cancer. The study sample were women who reported whether ever diagnosed with cervical cancer, who had pubertal daughters (n=1,578). Data were analyzed by cross-tabulation analysis, Spearman's rank correlation analysis, and logistic regression.

RESULTS

Mothers diagnosed with cervical cancer were more confident in using methods to prevent cervical cancer in their daughters (Z=-4.42, p<.001) and were more likely to feel negative emotions about the assumption of their daughters' HPV infection (Z=-2.44, p=.015) than mothers who were not diagnosed. Significant factors influencing their intention to recommend the HPV vaccination to their daughters were the mother's confidence in preventing cervical cancer in their daughters (odds ratio [OR], 1.003; 95% confidence interval [CI], 1.002-1.004) and their negative emotions about the assumption of their daughters' HPV infection (OR,1.016; 95% CI, 1.004-1.028).

CONCLUSION

For the early prevention of cervical cancer in pubertal daughters, the education of their mothers should include interventions to increase confidence in preventing cervical cancer in their daughters and sensitivity of HPV infection toward daughters.

Beliefs around childhood vaccines in the United States: A systematic review

BACKGROUND

While childhood vaccines are safe and effective, some parents remain hesitant to vaccinate their children, which has led to outbreaks of vaccine preventable diseases. The goal of this systematic review was to identify and summarize the range of beliefs around childhood vaccines elicited using open-ended questions, which are better suited for discovering beliefs compared to closed-ended questions.

METHODS

PubMed, Embase, and PsycINFO were searched using keywords for childhood vaccines, decision makers, beliefs, and attitudes to identify studies that collected primary data using a variety of open-ended questions regarding routine childhood vaccine beliefs in the United States. Study designs, population characteristics, vaccine types, and vaccine beliefs were abstracted. We conducted a qualitative analysis to conceptualize beliefs into themes and generated descriptive statistics.

RESULTS

Of 1727 studies identified, 71 were included, focusing largely on parents (including in general, and those who were vaccine hesitant or at risk of hesitancy). Seven themes emerged: Adverse effects was most prominent, followed by mistrust, perceived lack of necessity, pro-vaccine opinions, skepticism about effectiveness, desire for autonomy, and morality concerns. The most commonly described beliefs included that vaccines can cause illnesses; a child's immune system can be overwhelmed if receiving too many vaccines at once; vaccines contain harmful ingredients; younger children are more susceptible to vaccine adverse events; the purpose of vaccines is profit-making; and naturally developed immunity is better than that acquired from vaccines. Nearly a third of the studies exclusively assessed minority populations, and more than half of the studies examined beliefs only regarding HPV vaccine.

CONCLUSIONS

Few studies used open-ended questions to elicit beliefs about vaccines. Many of the studies that did so, focused on HPV vaccine. Concerns about vaccine safety were the most commonly stated beliefs about childhood vaccines, likely because studies were designed to capture barriers and challenges to vaccination.

Evaluation of Educational Interventions to Enhance Adolescent Specific Vaccination Coverage

BACKGROUND

In this study, we assessed impact of two educational interventions designed to increase coverage of three vaccines recommended during adolescence among Georgia middle and high school students (tetanus diphtheria pertussis [Tdap], meningococcal [MenACWY], and human papillomavirus [HPV] vaccines).

METHODS

We randomized 11 middle and high schools in one school district into one of three arms: (1) control; (2) educational intervention for parents only (P only); and (3) multicomponent educational intervention for parents and adolescents (P + A), which consisted of educational brochures for parents about vaccines recommended during adolescence and a vaccine-focused curriculum delivered to adolescents by science teachers. We obtained vaccination coverage data during intervention years from the state immunization registry.

RESULTS

Odds of receiving at least one vaccine during the study were higher among adolescents in P + A arm compared to control (Odds Ratio [OR]: 1.4; 95% Confidence Interval [CI]: 1.1-2.0). Adolescents in P + A arm had greater odds of receiving at least one vaccine compared with those in P only arm (OR: 1.4; 95% CI: 1.1-1.7).

CONCLUSIONS

A multicomponent educational intervention for adolescents and parents increased adolescent vaccination uptake. Results suggest similar interventions can increase awareness and demand for vaccines among parents and adolescents.

What kind of 'a girls' thing'? Frictions and continuities in the framing and taming of the HPV vaccine in Finland

This article focuses on two different ways of framing and taming the uncertainties of the human papillomavirus (HPV) vaccine in the context of the Finnish welfare state: the bio-medical rationale of population-level cancer reduction based on epidemiological assessments, and the meaning formation of Finnish vaccination-aged girls. Epidemiologists run analyses estimating the cost-effectiveness and public health benefit of vaccinations, while the adolescent girls face the burdensome choice of whether to undergo vaccination. The processes of framing the complexities and actively taming them are analysed utilising a cultural-sociological framework. Firstly, the taming work of the epidemiologists is examined by focusing on the creation of the vaccination campaign. The aetiological complexities between some HPV types and cervical cancer are tamed into a clear campaign message of vaccination as a scientifically proven protection against deadly cancer. Secondly, the girls' own ways of framing the complexities of the HPV vaccine and taming the decision whether to undergo vaccination or not are analysed based on their comments in an Internet discussion forum. Finally, the framings and tamings of both sites are discussed together, and some interesting continuities and disjunctions between the two are revealed.

Sense & sensibility: Decision-making and sources of information in mothers who decline HPV vaccination of their adolescent daughters

•

A good first and overall impression is key to vaccine uptake.

•

GP recommendation increases the likelihood of HPV vaccination.

•

Mothers with a higher educational level are likely to accept HPV vaccination.

•

Fathers taking part in the decision increases the likelihood of HPV vaccination.

•

Valuing news and media stories decreases the likelihood of HPV vaccination.

Background

Vaccination against human papillomavirus (HPV) has been part of the Danish Childhood Vaccination Programme (CVP) since 2009 and initially had a high uptake. Following an intense public debate on the alleged side-effects to the vaccine in 2015, coverage rates declined dramatically leaving the current coverage at 54%.

The main aim of this study was to identify differences in the sources of information and factors of importance in mothers’ decision to have or not to have their adolescent daughters vaccinated against HPV.

Methods

This cross-sectional study was based on survey and register data from 3,558 mothers of daughters born in 2003 living in the Central Denmark Region. The survey examined, among others, sources of information and factors of value in the decision-making process. Socioeconomic register data were retrieved from Statistics Denmark.

Pearson's chi-squared test was used to determine differences in socioeconomic distribution between both respondents and non-respondents, and mothers who had their daughters vaccinated versus those who did not. Associations between vaccination status and various events were estimated using logistic regression.

Results

A strong association was found between vaccine uptake and general practitioner (GP) recommendation (odds ratio (OR) 0.17, 95% confidence interval (CI) 0.10; 0.30), seeking GP guidance (OR 0.63, 95% CI 0.50; 0.78) and agreeing with the daughter’s father to vaccinate (OR 0.60, 95% CI 0.37; 0.96). Inversely, vaccination decline was associated with a negative first impression of HPV vaccination (OR 4.05, 95% CI 3.28; 5.00), valuing media stories (OR 3.57, 95% CI 2.63; 4.85) and distrusting the first source of information (OR 2.49, 95% CI 1.92; 3.23).

Conclusions

The results indicate that the impression left behind by information sources is more important in determining vaccination status than the information sources themselves, indicating that mothers are liable to make healthcare decisions based on sensibility rather than sense.

Persuasive messaging for human papillomavirus vaccination by adolescent providers in a five-country multi-site study

OBJECTIVE

Strong persuasive messaging by providers is a key predictor for patient acceptance of prophylactic human papillomavirus vaccination. We aimed to determine optimal messaging to promote human papillomavirus adolescent vaccination across different geographical sites.

METHODS

Adolescent providers (n = 151) from Argentina, Malaysia, South Africa, South Korea, and Spain were surveyed on messages, family decision makers, and sources of communication to best motivate parents to vaccinate their adolescent daughters overall, and against human papillomavirus. Multivariate logistic regression assessed the likelihood of recommending messages specifically targeted at cervical cancer with providers' characteristics: gender, medical specialization, and previous administration of human papillomavirus vaccination.

RESULTS

Mothers were considered the most important human papillomavirus vaccination decision makers for their daughters (range 93%-100%). Television was cited as the best source of information on human papillomavirus vaccination in surveyed countries (range 56.5%-87.1%), except Spain where one-on-one discussions were most common (73.3%). Prevention messages were considered the most likely to motivate parents to vaccinate their daughters overall, and against human papillomavirus, in all five countries (range 30.8%-55.9%). Optimal messages emphasized cervical cancer prevention, and included strong provider recommendation to vaccinate, vaccine safety and efficacy, timely vaccination, and national policy for human papillomavirus vaccination. Pediatricians and obstetricians/gynecologists were more likely to cite that the best prevention messages should focus on cervical cancer (OR: 4.2, 95% CI: 1.17 to 15.02 vs other medical specialists).

CONCLUSIONS

Provider communication messages that would motivate parents to vaccinate against human papillomavirus were based on strong recommendation emphasizing prevention of cervical cancer. To frame convincing messages to increase vaccination uptake, adolescent providers should receive updated training on human papillomavirus and associated cancers, while clearly addressing human papillomavirus vaccination safety and efficacy.

Cancer Prevention Education for Providers, Staff, Parents, and Teens Improves Adolescent Human Papillomavirus Immunization Rates

OBJECTIVE

To develop a program to educate providers, office staff, patients, and parents on life-long cancer prevention strategies, including the use of human papillomavirus (HPV) vaccine to improve adolescent HPV vaccination rates.

STUDY DESIGN

A 2-phase program was implemented at 6 pediatric practices across upstate New York. Phase 1 included provider and staff education regarding practice-specific vaccination challenges and discussion of the contents of a study-specific cancer-prevention booklet, which included HPV vaccine information. Throughout phase 2, the booklets were distributed to all adolescents and their parents during office visits over a 12-month period. Practice-specific, countywide, and statewide HPV vaccination rates were assessed before phase 1, and 6 and 12 months after the launch of phase 2.

RESULTS

One year after implementing phase 2 in 6 practices, adolescent HPV vaccine series initiation increased by at least 10% in 3 practices, and at least 5% in 5 practices. Similarly, adolescent vaccine series completion rates increased by more than 10% in 3 practices. The percent change in vaccine series completion rates across all study sites postintervention ranged from 12% to 20% for 11- to 12-year-olds, and from 7% to 23% for 13- to 18-year-olds.

CONCLUSIONS

Cancer prevention education targeting providers, office staff, patients, and parents was modestly effective for improving adolescent HPV vaccination rates.

Human papillomavirus vaccine motivators and barriers among community college students: Considerations for development of a successful vaccination program

BACKGROUND

Previous interventions in colleges to improve human papillomavirus (HPV) vaccination have not been highly successful. Although barriers have been assessed in traditional colleges, less is known about vaccination barriers in community colleges.

METHODS

We approached students aged 18-26 years old enrolled at a community college for an in-person semi-structured qualitative interview on HPV vaccination and health, with questions guided by the Theory of Planned Behavior. Data collection took place between April 2015 and December 2015. Thematic analysis techniques were used to analyze the data.

RESULTS

During interviews with 19 students, 4 themes emerged, including: general vaccine attitudes, barriers to HPV vaccination, motivators to HPV vaccination, and social influences. Participants felt that vaccines were beneficial, but were concerned about side effects. They felt that getting the HPV vaccine would be inconvenient, and they did not know enough about it to decide. Most would not trust their friends' opinions, but would want to know about side effects that their vaccinated friends experienced.

CONCLUSIONS

Successful interventions at community colleges should include several components to increase convenience as well as utilize interactive methods to promote HPV vaccine awareness.

Parents' Views on the Best and Worst Reasons for Guideline-Consistent HPV Vaccination

Background: Human papillomavirus (HPV) vaccination could prevent most HPV-associated cancers, but few U.S. adolescents are vaccinated according to guidelines. To inform efforts to counsel parents more effectively, we sought to quantify their views on the best and worst reasons for guideline-consistent HPV vaccination. We hypothesized that parents' views would differ according to their vaccination confidence.Methods: We developed a best-worst scaling experiment to evaluate 11 reasons healthcare providers commonly give for HPV vaccination. The instrument was administered in 2016 via a national online survey to 1,177 parents of adolescents. Parents completed 11 choice tasks of 5 reasons each, indicating the best and worst reason in each task. We used conditional logistic regression to rank reasons for the sample overall and by vaccination confidence (low/high).Results: Parents viewed cancer prevention as the best reason for HPV vaccination (P < 0.001). Other commonly endorsed reasons were preventing a common infection, having lasting benefits, or being a safe vaccine (all P < 0.001). Reasons viewed as worst were: It is a scientific breakthrough; I got it for my own child; and your child is due (all P < 0.001). Stratified analyses indicated small differences in how often parents with low versus high vaccination confidence endorsed messages (P < 0.001), but the two groups ranked reasons similarly overall.Conclusions: Parents prioritized cancer prevention as the best reason for guideline-consistent HPV vaccination. Several other common reasons, including having vaccinated one's own child, may warrant additional testing.Impact: Providers should emphasize cancer prevention when discussing HPV vaccination, as recommended by the Centers for Disease Control and Prevention, the President's Cancer Panel, and others.

Barriers to HPV Vaccination Among Unvaccinated, Haitian American College Women

Background: Haitian women residing in the United States are disproportionately affected by cervical cancer. Human papillomavirus (HPV) vaccine has been licensed in the United States since 2006. Vaccination rates are less than optimal overall, and the rates are particularly low among young black women. We investigated barriers to HPV vaccination in a sample of Haitian American college women. Methods: Thirty self-identified Haitian American women, aged 17-26 years, were recruited from a large university campus in southeastern United States (n=30). They completed in-depth face-to-face interviews. The research team analyzed the transcripts using thematic analysis. Results: More than half of the participants (n=18) had not yet initiated the HPV vaccine series. Most of the unvaccinated participants stated that they had received a provider recommendation for the vaccine. Lack of provider recommendation, negative vaccine perception and attitudes, and side effect concerns constituted barriers to vaccination. Conclusions: Haitian American college women at high risk of cervical cancer have cited several barriers to HPV vaccination, with the most prominent being lack of physician recommendation. Healthcare providers should continue recommending the vaccine to college women as many of them may not have received a recommendation. When recommending the HPV vaccine, discussions should be framed with the intent to positively influence HPV vaccine perceptions and ultimately vaccine attitudes.

Factors that Predict Parental Willingness to Have Their Children Vaccinated against HPV in a Country with Low HPV Vaccination Coverage

Background: Adolescent HPV (Human Papilloma Virus) vaccination is yet to be introduced as a mandatory program in Poland. Polish literature on factors associated with adolescent HPV vaccination is scant, despite the fact that uptake is one of the poorest in the European Union. Objectives: To assess HPV awareness and identify independent predictors for parental willingness to have their children vaccinated against HPV. Methods: All parents of first grade students from three selected high schools in Zgorzelec, Poland, who participated in parent–teacher meetings at the time the study was conducted, had their children unvaccinated regarding HPV, and who gave informed consent to participate were included. There were 600 first grade students; 9 were vaccinated against HPV. This left 591 parents who met the eligibility criteria; the response rate was 76.1%. Results: Awareness of HPV was reported by 55.3% of 450 parents (mean age 42 years, 70.9% females); 85.1% expressed their willingness to vaccinate their children against HPV; 31.3% identified HPV as a sexually transmitted pathogen, and 36.2% identified it as a risk factor of cervical cancer. Multivariable logistic regression analyses indicated that being employed (OR 2.09; 95% CI: 1.10–3.86), having positive attitudes toward vaccines (OR 3.02; 95% CI: 1.34–6.49), previous information about HPV (OR 2.02; 95% CI: 1.17–3.51), and concerns about the side effects of the HPV vaccine (OR 0.60; 95% CI: 0.35–0.99) were independent predictors of parents’ willingness to vaccinate. Conclusions: Attitudes regarding their child being vaccinated against HPV were positive among Polish parents, even though awareness and knowledge of HPV in this group were low. Most of the significant factors that influenced their willingness were modifiable, such as being informed about HPV and having positive attitudes toward vaccines. Future interventions should focus specifically on vulnerable subgroups, such as unemployed parents.

Knowledge and Attitudes of Postpartum Mothers towards Immunization of Their Children in a Lithuanian Tertiary Teaching Hospital

Background: Sufficient vaccination coverage among children depends on parents' knowledge and attitudes towards immunization and their intention to have their children vaccinated. The objective of the study was to evaluate postpartum mothers' knowledge and attitudes towards children's immunization. Methods: It was a cross-sectional survey. The anonymous questionnaire was handed out to postpartum mothers selected at random in the Hospital of Lithuanian University of Health Sciences Kauno Klinikos from March to July of 2014. In total, 300 women were surveyed. Results: The majority (63%) of respondents had higher education. The child was the first one for 49.7% of the mothers. The women indicated that their main sources of information about children's vaccination were the doctor, the Internet and mass media. Most respondents (87.3%) considered vaccine-preventable diseases to be dangerous but only 57.3% of them knew that vaccines provided efficient protection. Only 57% of the respondents considered vaccines to be safe but 75.3% thought that the benefits of vaccines were greater than the risks. We evaluated the knowledge as good in 36.3%, average in 41.3% and poor in 22.3% of mothers. Most of the respondents (81.3%) planned to immunize their child in the future with all the vaccines included in the national immunization program, however, 72.7% were worried about possible adverse events following vaccination. Of the mothers whose knowledge was evaluated as good, 74.8% had never refused or had doubts about having their child immunized (τ = -0.198, p < 0.001). The mothers with better knowledge were also less likely to be concerned (τ = 0.211, p < 0.001). Conclusions: Evaluation of postpartum mothers' knowledge and attitudes towards children's immunization could be the tool for better communication between health professionals and parents leading to increased vaccination rates.

Parents' knowledge, beliefs, and acceptance of the HPV vaccination in relation to their socio-demographics and religious beliefs: A cross-sectional study in Thailand

Thailand has one of the world's highest prevalence of cervical cancer, mainly caused by the human papillomavirus (HPV). HPV infections can successfully be prevented by vaccination, which is available at a cost but not yet implemented in the national vaccination program. Parents play a critical role in deciding whether to vaccinate their child against HPV. Thus, the aim was to examine the association between parents' knowledge, beliefs, and acceptance of the HPV vaccination for their daughters, considering their socio-demographics and religious beliefs. A cross-sectional design was used among three schools in Thailand: Nakorn Phatom province (suburban) and Bangkok (urban). Parents of 9-12-year-old daughters completed the questionnaires, guided by the Health Belief Model. In total, 359 parents completed the questionnaires; of those, 301 were included in the final analyses. The ordinary least squares (OLS) regression analysis showed that background knowledge of HPV and the HPV vaccine was positively related to knowledge of HPV and cervical cancer. For beliefs, knowledge was positively associated with susceptibility (i.e., parents' perceived risk of an HPV infection/ related disease), severity, and benefit. However, knowledge was not significantly related to barriers. For acceptance, higher susceptibility and benefit were related to higher acceptance, and greater knowledge was associated with higher acceptance. Thus, we found associations between parents' knowledge, beliefs, and acceptance of the HPV vaccination for their daughters, considering their socio-demographics and religious beliefs. Parents, who reported religion as important, as opposed to those who did not, were more favorable toward the HPV vaccination. Four out of ten mothers had never undergone a cervical cancer screening, but most had accepted previous childhood vaccinations for their daughters. The overall acceptance of the vaccine was high, and we believe our results are promising for future implementation of the HPV vaccination in the national childhood vaccination program in Thailand.

Adolescent-Parent Dyad Descriptions of the Decision to Start the HPV Vaccine Series

STUDY OBJECTIVE

To examine how adolescent-parent dyads describe decision-making regarding initiation of the human papillomavirus (HPV) vaccine series, specifically who they viewed as making the final decision.

DESIGN

Semistructured interviews with adolescent-parent dyads were audio-recorded and transcribed. Responses to the question: "How did you make a decision about whether or not to receive the HPV vaccine series?" were content-coded for each individual member of the dyad.

SETTING

Adolescent medicine clinics of 2 large urban medical centers and through snowball sampling.

PARTICIPANTS

Adolescents 14-17 years of age and a parent (N = 262). Qualitative analyses were conducted for those who agreed that they were offered and started the HPV vaccine series (n = 109).

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

Descriptions of the decision-making included 1 person (adolescent or parent) making the decision or joint decision-making by the adolescent and parent together.

RESULTS

More than half of the dyads did not agree on who made the decision to start the vaccine. Most adolescents and parents described a similar account about when they were offered the HPV vaccine, although the interpretation of the event in terms of the decision-maker might have differed. More than half of adolescents and parents individually mentioned the health care provider in their description of the HPV vaccine decision-making process even though they were not queried about the role of the provider.

CONCLUSION

Understanding the range of descriptions of these dyads is helpful to guide interventions to promote vaccine uptake in a manner that balances provider expertise, adolescent autonomy, and parental involvement.

To vaccinate or not to vaccinate? Perspectives on HPV vaccination among girls, boys, and parents in the Netherlands: a Q-methodological study

BACKGROUND

Despite the introduction of Human papillomavirus (HPV) vaccination in national immunization programs (NIPs), vaccination rates in most countries remain relatively low. An understanding of the reasons underlying decisions about whether to vaccinate is essential in order to promote wider spread of HPV vaccination. This is particularly important in relation to policies seeking to address shortfalls in current HPV campaigns. The aim of this study was to explore prevailing perspectives concerning HPV vaccination among girls, boys, and parents, and so to identify potential determinants of HPV vaccination decisions in these groups.

METHOD

Perspectives were explored using Q-methodology. Forty-seven girls, 39 boys, and 107 parents in the Netherlands were asked to rank a comprehensive set of 35 statements, assembled based on the health belief model (HBM), according to their agreement with them. By-person factor analysis was used to identify common patterns in these rankings, which were interpreted as perspectives on HPV vaccination. These perspectives were further interpreted and described using data collected with interviews and open-ended questions.

RESULTS

The analysis revealed four perspectives: "prevention is better than cure," "fear of unknown side effects," "lack of information and awareness," and "my body, my choice." The first two perspectives and corresponding determinants of HPV vaccination decisions were coherent and distinct; the third and fourth perspectives were more ambiguous and, to some extent, incoherent, involving doubt and lack of awareness and information (perspective 3), and overconfidence (perspective 4).

CONCLUSIONS

Given the aim of publically funded vaccination programs to minimize the spread of HPV infection and HPV-related disease and the concerns about current uptake levels, our results indicate that focus should be placed on increasing awareness and knowledge, in particular among those in a modifiable phase.

Human Papillomavirus Vaccination: What Are the Reasons for Nonvaccination Among U.S. Adolescents?

PURPOSE

Human papillomavirus (HPV) vaccination is recommended for 11- to 12-year-old U.S. adolescents. Unfortunately, HPV vaccine rates have been suboptimal. Parents are key decision agents regarding their adolescents' health; thus, it is necessary to understand their reasons for not vaccinating their adolescents. The purpose of this study was to compare parents' primary reasons for non-HPV vaccination by calendar year, sex of the child, and level of vaccine hesitancy.

METHODS

The National Immunization Survey-Teen 2012-2015 was subset to parents who did not intend for their adolescent to receive the HPV vaccine in the next 12 months (N = 59,897). Survey-weighted logistic regression models assessed the impact of year, sex, and level of hesitancy on main reasons for nonvaccination.

RESULTS

Not receiving a recommendation and lack of knowledge were significantly more likely to be the reasons for nonvaccination in 2012 and 2013 compared with 2015. The following reasons were significantly less likely to be reported for females compared with males: not recommended (odds ratio [OR] = .63, 95% confidence interval [CI], .58-.69) and lack of knowledge (OR = .86, 95% CI, .79-.94). In contrast, parents of females were more likely to state they were concerned about safety and side effects (OR = 2.19, 95% CI, 1.98-2.41). Differences in reasons for nonvaccination were observed between those who were unlikely and unsure regarding receiving the HPV vaccine.

CONCLUSIONS

Findings indicate that U.S. parental attitudes about HPV vaccination have changed over time and reasons for nonvaccination vary based on the sex of the adolescent and the level of hesitancy of the parent. This information can shape how providers respond to parental concerns and HPV vaccine hesitancy.

Cervical Cancer Prevention in Malaysia: Knowledge and Attitude of Undergraduate Pharmacy Students Towards Human Papillomavirus Infection, Screening and Vaccination in Malaysia

This study was conducted to evaluate knowledge of undergraduate pharmacy students about human papillomavirus infection and their attitude towards its prevention. A cross-sectional survey was conducted in 270 undergraduate pharmacy students using a validated questionnaire to assess knowledge about human papillomavirus infection and cervical cancer and their attitudes towards human papillomavirus vaccines. Eighty-one percent of the respondents knew that human papillomavirus is a cause of cervical cancer, and 87.8 % knew that this infection is preventable. The gender of the respondents showed the strongest correlations with human papillomavirus knowledge. There were no significant correlations between the ethnic group of the respondents and their human papillomavirus-related knowledge. Higher perceptions of risk were associated with relationship status, and respondents who were in a relationship showed greater interest in vaccinating themselves; relationship status emerged as a unique predictor. The results indicated a moderately high level of knowledge and positive attitude towards human papillomavirus vaccination with few disagreements. The results of this study will help to develop and plan appropriate education campaigns for pharmacy students that aim to reduce human papillomavirus infection and, consequently, the incidence of and mortality caused by cervical cancer in Malaysia.

Associations of trust and healthcare provider advice with HPV vaccine acceptance among African American parents

OBJECTIVE

Healthcare providers (HCPs) are advised to give all parents a strong recommendation for HPV vaccination. However, it is possible that strong recommendations could be less effective at promoting vaccination among African Americans who on average have greater mistrust in the healthcare system. This study examines the associations of parental trust in HCPs and strength of HCP vaccination recommendation on HPV vaccine acceptance among African American parents.

METHODS

Participants were recruited from an urban, academic medical center between July 2012 and July 2014. We surveyed 400 African American parents of children ages 10-12years who were offered HPV vaccine by their HCPs to assess sociodemographic factors, vaccine beliefs, trust in HCPs, and the HPV vaccine recommendation received. Medical records were reviewed to determine vaccination receipt.

RESULTS

In multivariable analysis, children whose parents were "very strongly" recommended the HPV vaccine had over four times higher odds of vaccine receipt compared with those whose parents were "not very strongly" recommended the vaccine. Having a parent with "a lot of" versus "none" or only "some" trust in HCPs was associated with over twice the odds of receiving HPV vaccine. Very strong HCP recommendations were associated with higher odds of vaccination among all subgroups, including those with more negative baseline attitudes toward HPV vaccine and those with lower levels of trust. Adding the variables strength of HCP recommendation and parental trust in HCPs to a multivariable model already adjusted for sociodemographic factors and parental vaccine beliefs improved the pseudo R² from 0.52 to 0.55.

CONCLUSIONS

Among participants, receiving a strong vaccine recommendation and having a higher level of trust in HCPs were associated with higher odds of HPV vaccination, but did not add much to the predictive value of a model that already adjusted for baseline personal beliefs and sociodemographic factors.

Parents who refuse or delay HPV vaccine: Differences in vaccination behavior, beliefs, and clinical communication preferences

BACKGROUND

We sought to estimate the national prevalence of HPV vaccine refusal and delay in a nationally-representative sample of parents of adolescents. We also compared parents who refused versus delayed HPV vaccine in terms of their vaccination beliefs and clinical communication preferences.

METHODS

In 2014 to 2015, we conducted an online survey of 1,484 US parents who reported on an 11- to 17-year-old child in their household. We used weighted multinomial logistic regression to assess correlates of HPV vaccine refusal and delay.

RESULTS

Overall, 28% of parents reported that they had ever "refused or decided not to get" HPV vaccine for their child, and an additional 8% of parents reported that they had "delayed or put off getting" HPV vaccine. Compared to no refusal/delay, refusal was associated with lower confidence in adolescent vaccination (relative risk ratio [RRR] = 0.66, 95% confidence interval [CI], 0.48-0.91), lower perceived HPV vaccine effectiveness (RRR = 0.68, 95% CI, 0.50-0.91), and higher perceived harms (RRR = 3.49, 95% CI, 2.65-4.60). In contrast, delay was associated with needing more information (RRR = 1.76, 95% CI, 1.08-2.85). Most parents rated physicians and information sheets as helpful for making decisions about HPV vaccination, although parents who reported refusal endorsed these resources less often.

CONCLUSIONS

Our findings suggest that HPV vaccine refusal is common among parents of adolescents and may have increased relative to previous estimates. Because the vaccination beliefs and communication preferences of parents who refuse appear to differ from those who delay, targeted communication strategies may be needed to effectively address HPV vaccine hesitancy.

Expectation prior to human papilloma virus vaccination: 11 to 12-Year-old girls' written narratives

Expectations prior to needle-related procedures can influence individuals' decision making and compliance with immunization programmes. To protect from human papilloma virus (HPV) and cervical cancer, the immunization needs to be given before sexual debut raising interest for this study's aim to investigate how 11 to 12-year-old girls narrate about their expectations prior to HPV vaccination. A total of 27 girls aged 11 to 12 years participated in this qualitative narrative study by writing short narratives describing their expectations. The requirement for inclusion was to have accepted HPV vaccination. Data were subjected to qualitative content analysis. Findings showed the following expectations: going to hurt, going to be scared and going to turn out fine. The expectations were based on the girls' previous experiences, knowledge and self-image. The latent content revealed that the girls tried to transform uneasiness to confidence. The conclusion drawn from this study is that most girls of this age seem confident about their ability to cope with possible unpleasantness related to vaccinations. However, nurses need to find strategies to help those children who feel uneasy about needle-related procedures.

Provider communication about HPV vaccination: A systematic review

BACKGROUND

Improving HPV vaccination coverage in the US will require healthcare providers to recommend the vaccine more effectively. To inform quality improvement efforts, we systematically reviewed studies of provider communication about HPV vaccination.

METHODS

We searched MEDLINE, CINAHL, EMBASE, and POPLINE in August 2015 to identify studies of provider communication about HPV vaccination.

RESULTS

We identified 101 qualitative and quantitative studies. Providers less often recommended HPV vaccine if they were uncomfortable discussing sex, perceived parents as hesitant, or believed patients to be low risk. Patients less often received recommendations if they were younger, male, or from racial/ethnic minorities. Despite parents' preference for unambiguous recommendations, providers often sent mixed messages by failing to endorse HPV vaccine strongly, differentiating it from other vaccines, and presenting it as an "optional" vaccine that could be delayed.

CONCLUSION

Interventions are needed to help providers deliver effective recommendations in the complex communication environment surrounding HPV vaccination.

Influence of sources of information about influenza vaccine on parental attitudes and adolescent vaccine receipt

In 2011-2012, only 34% of 13-17 years olds in the United States (US) received seasonal influenza vaccine. Little is known about the link between parents' sources of health information, their vaccine-related attitudes, and vaccination of their adolescent against influenza. This study seeks to determine the relationship between number of sources of information on influenza vaccine, parental attitudes toward influenza vaccine, and influenza vaccine uptake in adolescents. We conducted a telephone and web-based survey among US parents of students enrolled in 6 middle and 5 high schools in Georgia. Bivariate and multivariable analyses were conducted to examine associations between the number of information sources about influenza vaccine and vaccine receipt and whether parent vaccine-related attitudes act as a mediator. The most commonly reported sources of information were: a physician/medical professional (95.0%), a family member or friend (80.6%), and television (77.2%). Parents who had higher attitude scores toward influenza vaccine were 5 times as likely to report their adolescent had ever received influenza vaccine compared to parents who had lower attitude scores (adjusted odds ratio (aOR) 5.1; 95% confidence intervals (CI) 3.1-8.4; P < 0.01). Parent vaccine-related attitudes were a significant mediator of the relationship between sources of information and vaccine receipt. In light of the low response rate and participation in an adolescent vaccination intervention, findings may not be generalizable to other populations. This study shows the importance of multiple sources of information in influencing parental decision-making about influenza vaccine for adolescents. Harnessing the power of mass media and family members and friends as health advocates for influenza vaccination can potentially help increase vaccination coverage of adolescents.

Student HPV vaccine attitudes and vaccine completion by education level

PURPOSE

We describe HPV vaccine attitudes among students of different education levels.

METHODS

High school, college, and graduate-level health care professional students were surveyed regarding HPV vaccine knowledge, attitudes, and receipt. Relationships between categorical variables were analyzed using chi-square tests of independence and z-tests for proportions. Means for quantitative variables were compared using t-tests and one-way analysis of variance.

RESULTS

57% and 42% of the 889 students reported starting and completing HPV vaccine series, respectively, with no statistical difference by education level. 61% of students who reported receiving a provider recommendation had completed the series, compared to 6% of those who did not receive recommendation (p<0.001). The belief that HPV vaccine prevents cancer was strongly associated with vaccine completion (p=0.003).

CONCLUSION

HPV vaccine coverage rates remain suboptimal. Future interventions should focus on improving provider recommendation and patient belief that HPV vaccine prevents cancer.

Awareness and acceptance of human papillomavirus vaccination among health sciences students in Malaysia

The major cause of cervical cancer is human papillomavirus (HPV) for which vaccination is available. The success HPV vaccination programme largely depend on the degree of knowledge of the healthcare providers who can recommend to the public. Health sciences students as future healthcare providers play a major role in HPV vaccination initiatives. The objective of this study was to evaluate the knowledge, attitude, practice and to find out the willingness to pay for HPV vaccination among the health sciences students in a private university. The cross-sectional study was conducted among the university students studying health sciences program using a validated questionnaire to measure their awareness and acceptance of HPV vaccination. The students demonstrated moderate knowledge about HPV infection and vaccination with mean knowledge scores of 9.3 out of 17. Students were showing positive attitude towards HPV vaccination with mean scores of 3.80 out of 5. However, low HPV vaccination uptake rate was reported among the students. Most of the students were willing to recommend HPV vaccine. The participants felt that the cost is the major barrier towards HPV vaccination and they felt the government should cover the cost of vaccination for all. The results of this study may be helpful in establishing educational policies on cervical cancer-related topics in the universities.

Parental intention regarding the administration of the HPV vaccine for adolescent daughters in Taiwan

This study aimed to investigate parental intention regarding the human papilloma virus (HPV) vaccination for adolescent daughters. Parents or guardians of adolescent girls, aged 12-14 years, from junior high schools in Taiwan participated and completed a HPV vaccination intention survey based on the Theory of Planned Behavior. The survey was conducted from October to November, 2009. Most, 78%, of the respondents reported a high intention to vaccinate daughters against HPV. A high intention of vaccination was associated with a family history of gynecological tumors (adjusted odds ratio [OR]: 2.22, 95% confidence interval [CI]: 1.10-4.51) and HPV awareness (adjusted OR: 2.33, 95% CI: 1.45-3.76). Higher parental intention was reported by respondents with a positive attitude toward the HPV vaccine (adjusted OR: 6.83, 95% CI: 4.16-11.22), perceived greater influence of subjective norms (adjusted OR: 121.23, 95% CI: 42.69-344.21), greater perceived behavioral control (adjusted OR: 67.69, 95% CI: 16.40-279.41), and perceived that the vaccine had limited influence on adolescent sexual behavior (adjusted OR: 2.24, 95% CI: 1.41-3.78). Health-care professionals must be knowledgeable about the HPV and actively promote vaccination among adolescent girls. Improvements in vaccination can be achieved through recommendations by physicians and nurses.

Medical and sociodemographic factors associated with human papillomavirus (HPV) vaccination adherence among female survivors of childhood cancer

BACKGROUND

Among those 9-26 years of age, vaccination can prevent specific types of genital human papillomavirus (HPV), the most common sexually transmitted infection and cause of cervical and other cancers. The objective of this study was to estimate the prevalence of and factors associated with HPV vaccine initiation and completion among females surviving childhood cancer.

PROCEDURE

One-hundred fourteen young adults and 230 mothers with daughters surviving childhood cancer completed surveys querying HPV vaccination history along with medical and sociodemographic factors potentially associated with vaccination outcomes. Vaccination rate differences by age necessitated analysis of outcomes by age group: 9-13 years (preadolescents), 14-17 years (adolescents), and 18-26 years (young adults). Multivariable logistic regression was utilized to identify factors associated with HPV vaccination outcomes.

RESULTS

Overall, 34.6% (119/344) of survivors initiated and 20.9% (72/344) completed HPV vaccination. Preadolescents were least likely to have initiated vaccination (P < 0.001). Physician recommendation was associated with initiation across age groups (OR = 6.81-11.96, Ps < 0.001-.01), whereas older age at diagnosis (≥12 years of age) was associated with lower vaccination initiation among young adults only (OR = 0.28; 95%CI, 0.10-0.76, P = 0.012). Physician recommendation (OR = 7.54; 95%CI, 1.19-47.69, P = 0.032; adolescent group) and greater treatment intensity (OR = 5.25; 95%CI, 1.00-27.61, P = 0.050; young adult group) were associated with vaccine completion, whereas being non-White was associated with decreased vaccination completion (OR = 0.17; 95%CI, 0.05-0.66, P = 0.010; adolescent group).

CONCLUSIONS

A minority of youths surviving childhood cancer have initiated or completed HPV vaccination. Strategies to increase vaccination among survivors are discussed.

HPV Vaccine Public Awareness Campaigns: An Environmental Scan

Human papillomavirus (HPV) vaccination rates are significantly lower than recommended targets. Public awareness campaigns can raise awareness of the severity and prevalence of HPV infection and the cancer prevention benefits of the vaccine. We conducted an environmental scan of HPV vaccine public awareness campaigns during the summer of 2014. We used online search strategies and expert input to identify candidate campaigns. Multiple study investigators reviewed all data abstraction and analysis. After applying our inclusion criteria, we identified 14 campaigns with parents or teenagers as the target audience. We characterized campaign messages according to constructs of the Health Belief Model. Most messages focused on the cancer prevention benefits of HPV vaccine; few addressed psychological or practical barriers to getting or completing the vaccine. Four of 14 campaigns had pre- or postcampaign data readily available, only 2 used vaccine outcomes in their evaluations. We concluded there was a high prevalence of HPV vaccine public awareness campaigns but little available evidence on their impact on intermediate or vaccine outcomes.

Effect of the decision-making process in the family on HPV vaccination rates among adolescents 9-17 years of age

The purpose of this study was to examine the relationship between human papillomavirus (HPV) vaccine uptake among adolescents aged 9-17 years and the decision-making process used by families in determining whether to vaccinate their children against HPV. A cross-sectional sample of women with at least one child aged 9-17 years (n = 1256) was recruited from 3 reproductive health clinics in Southeast Texas during 2011-2013. Self-administered survey included questions about the HPV vaccination decision-making process, HPV vaccine uptake (initiation and 3-dose series completion), and demographics. Among mothers with at least one 9 to 17-year-old daughter (n = 783), 40% independently decided whether or not to vaccinate their daughter against HPV, 22% involved their husbands/partners, and 31% their daughters. Only 7% of respondents reported other formats in the decision-making (husband/partner alone or daughter alone). Similarly, for women with at least one eligible son (n = 759), 39% decided alone, 30% with their husbands/partners, 24% with their sons, and 7% reported other formats. Among mothers with a daughter, those who made the decision independently were more likely to report that their daughters had initiated the HPV vaccine series (30%) compared with women who included their husbands/partners (10%) or daughters (20%) in the decision process or stated other types (18%) of decision making (P < 0.001). The respective figures for the completion of the entire series among daughters were 16%, 6%, 11%, and 11% (P = 0.012). Among mothers with a son, a similar scenario was observed for vaccine initiation (17%, 4%, 10%, and 0%, respectively) (P < 0.001) and completion (7%, 1%, 4%, and 0%, respectively) (P = 0.003). These associations remained significant after adjusting for confounder variables. Awareness programs to increase HPV vaccine uptake should include both parents and children, as all have an important role in deciding whether or not children will be vaccinated.

Do parental education and income matter? A nationwide register-based study on HPV vaccine uptake in the school-based immunisation programme in Norway

OBJECTIVE

Vaccine against human papillomavirus (HPV) has been offered free of charge to all 12-year-old girls in Norway since 2009. Nevertheless, the uptake of HPV vaccine is lower than for other childhood vaccines. The aim of this study was to examine whether parental education and income are associated with initiation and completion of HPV vaccination.

DESIGN

Nationwide register-based study.

SETTING

Publicly funded childhood immunisation programme in Norway.

PARTICIPANTS

91,405 girls born between 1997 and 1999 and registered in the Norwegian Central Population Registry were offered HPV vaccine during the first 3 programme years. Of these, 84,139 had complete information on all variables and were included in the study.

MEASUREMENTS

Information on HPV-vaccination status was obtained from the Norwegian Immunisation Registry. Data on socioeconomic factors were extracted from Statistics Norway. Risk differences (RDs) and CIs were estimated with Poisson regression.

RESULTS

In the study sample, 78.3% received at least one dose of HPV vaccine and 73.6% received all three doses. High maternal education was significantly associated with lower probability of initiating HPV vaccination (multivariable RD=-5.5% (95% CI -7.0% to -4.0%) for highest compared with lowest education level). In contrast, high maternal income was significantly associated with higher probability of initiating vaccination (multivariable RD=10.1% (95% CI 9.0% to 11.3%) for highest compared with lowest quintile). Paternal education and income showed similar, but weaker, associations. The negative association between education and initiation was only seen for incomes below the median value.

CONCLUSIONS

In spite of the presumably equal access to HPV vaccine in Norway, we found socioeconomic disparities in vaccine uptake. More studies are needed to explain the underlying factors responsible for the observed socioeconomic differences. Insight into these factors is necessary to target information and increase vaccination coverage to ultimately reduce HPV-related disease across socioeconomic barriers.

Effective dual method contraceptive use and HPV vaccination among U.S. adolescent and young adult females

BACKGROUND

Problem Behavior Theory posits that risky behaviors cluster in individuals, implying that protective behaviors may follow a similar pattern. The purpose of this study was to determine whether the protective behavior of effective dual method contraception use at first and most recent sexual intercourse is associated with HPV vaccination among adolescent and young adult females.

METHODS

National Survey of Family Growth (2006-2010) data were used to examine the association between women's contraception use during first and most recent sexual intercourse and HPV vaccination. Women aged 15 to 24 years (n = 1,820) served as the study sample.

FINDINGS

At first and last sexual intercourse, effective dual method contraception use was reported by 15.3% and 16.8% women, respectively; 27.8% reported receiving at least one dose of the human papillomavirus (HPV) vaccine. Higher HPV vaccination rates were observed among dual method users at first and last sexual intercourse (36.4% and 48.2%, respectively). This trend was also observed across age groups (15-19 year olds vs. 20-24 year olds). In adjusted models, among all respondents, dual users at last sexual intercourse were significantly more likely to be vaccinated, whereas at first sexual intercourse only younger dual users were more likely to report HPV vaccination.

CONCLUSIONS

Findings suggest that the protective behavior of dual method contraceptive use at first and most recent sexual intercourse may serve as a predictor of another complementary health behavior, HPV vaccination, particularly among adolescent females. More research is needed to understand behavioral clustering to design related multi-focused women's health interventions.
