McNeil CJ, Barr B, Munawar I, DeWitt ME, Myers JS, Shetty AK. Assessing Barriers to Human Papillomavirus (HPV) Vaccination in At-Risk Rural Communities of Western North Carolina, United States. Vaccines (Basel) 2023; 11:1785. [PMID: 38140189 PMCID: PMC10747883 DOI: 10.3390/vaccines11121785] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2023] [Revised: 11/18/2023] [Accepted: 11/21/2023] [Indexed: 12/24/2023] Open
Abstract
Human papillomavirus (HPV) vaccination among adolescents in rural, western North Carolina (NC) remains suboptimal. Data are needed to understand the barriers to HPV vaccination in these communities. We conducted a cross-sectional pilot study of parental attitudes and provider practices regarding HPV vaccination in rural western NC counties with lower HPV vaccination rates. Eight health department clinics were enrolled in the study. Further, 29 provider and 32 parent surveys were analyzed along with environmental scans. Median provider comfort regarding knowledge of HPV-associated diseases was 85% (IQR = 75-95), on a scale of 0-100% (100% representing complete comfort). Median parental comfort level regarding knowledge of HPV-associated diseases and the HPV vaccine was 75% (IQR = 50-89) and 75% (IQR = 49-96), respectively. Less than 25% of parents rated the HPV vaccine as 'extremely effective' against genital (16.7%) and anal cancers (17.9%). Parents were more likely to rate the vaccine as 'extremely effective' to 'very effective' if their child was female. There was no significant difference between parental- and provider-reported comfort with knowledge about HPV-associated diseases (p = 0.0725) and the HPV vaccine (p = 0.167). This study identified multiple opportunities to increase HPV vaccine coverage among unvaccinated adolescents at parental, provider, and clinic levels. Health education of rural NC residents and providers in public health settings may identify future interventions to increase HPV vaccine uptake.

Human Papillomavirus Vaccine Acceptance (HPV-VA) and Vaccine Uptake (HPV-VU): assessing the impact of theory, culture, and trusted sources of information in a Hispanic community. BMC Public Health 2023; 23:1781. [PMID: 37710232 PMCID: PMC10500881 DOI: 10.1186/s12889-023-16628-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Accepted: 08/26/2023] [Indexed: 09/16/2023] Open
Abstract
BACKGROUND Human papillomavirus (HPV) is the most common sexually transmitted infection and is associated with many types of cancers that disproportionately impact Hispanics. An HPV vaccine is available for individuals ages 9-45 that can prevent up to 90% of HPV-associated cancers. The current study investigates factors associated with accepting the HPV vaccine in a predominately Hispanic community. METHODS A cross-sectional study design with an online questionnaire was used to collect data from a community sample of adults between the ages 18-65 residing in a U.S./Mexico border city, El Paso, Texas. Theory-based factors (e.g., the Health Belief Model), culture-based factors (e.g., familism), and trusted sources of information were examined as predictors of HPV-vaccine acceptance (HPV-VA) and HPV-vaccine uptake (HPV-VU). RESULTS Community members (N = 602, Mage = 34.65, SD = 9.79) who were predominately Hispanic (89.4%) and female (79.6%) participated in the study. Linear regression models revealed that HPV-VA was associated with household size, primary language, engagement in organizational activities, health-related community stigma, government trust, and the HBM theory-based factors: perceived benefits, perceived harm, and perceived severity. Logistic regression analyses revealed that HPV-VU was associated with household size, engagement in non-organizational activities, HPV trusted sources of information, and perceived safety. CONCLUSIONS Adequate HPV vaccination uptake among all vaccine-eligible Hispanics is an important step to lessen the HPV-attributed cancer burden. Our hypothesis that theory-based factors would be associated with HPV-VA and HPV-VU was supported. Our findings have implications for designing trusted, theory-based, and culturally sensitive health communications and interventions to promote vaccines in minority underrepresented communities.

Abstract
Human papillomavirus (HPV) vaccine uptake among adolescents remains suboptimal in the US. The COVID-19 pandemic posed new challenges to increase HPV vaccination rates. To characterize parent-reported barriers to obtain HPV vaccination for their children and to identify psychosocial factors associated with parents' intention to vaccinate their children for HPV, we administered parent surveys between April 2020 and January 2022 during a randomized pragmatic trial assessing the impact of evidence-based implementation strategies on HPV vaccination rates for adolescent patients at six Mayo Clinic primary care practices in Southeast Minnesota. A total of 342 surveys were completed (response rate 34.1%). Analyses were focused on parents of unvaccinated children (n = 133). The survey assessed the main reason the child did not receive the HPV vaccine, parental beliefs about the vaccine, and the parent's intention to vaccinate the child for HPV in the next 12 months. Frequently reported awareness and access barriers to HPV vaccination included not knowing the child was due (17.8%) and COVID-19 related delay (11.6%). Frequently reported attitudinal barriers include the belief that the child was too young for the vaccine (17.8%) and that the vaccine is not proven to be safe (16.3%). Injunctive social norm (Adjusted-OR = 3.15, 95%CI: 1.94, 5.41) and perceived harm beliefs (Adjusted-OR = 0.58, 95%CI: 0.35, 0.94) about the HPV vaccine were positively and negatively associated with HPV vaccination intention, respectively. Our findings suggest that continued efforts to overcome parental awareness, access, and attitudinal barriers to HPV vaccination are needed and underscore the importance of utilizing evidence-based health system-level interventions.

Factors related to human papillomavirus vaccine uptake and intentions among adults aged 18-26 and 27-45 years in the United States: A cross-sectional study. Cancer 2023; 129:1237-1252. [PMID: 36759972 PMCID: PMC10470643 DOI: 10.1002/cncr.34680] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2022] [Revised: 09/20/2022] [Accepted: 09/22/2022] [Indexed: 02/11/2023]
Abstract
BACKGROUND The current study examined self-reported human papillomavirus (HPV) vaccination uptake and intentions, and associations with psychosocial constructs among United States adults aged 18 to 26 and 27 to 45 years. METHODS Data were collected via an online survey from participants recruited from a research panel. Outcomes were HPV vaccination uptake and intentions. Multivariable binary and ordered logistic regression models were used to examine associations between HPV vaccination outcomes and psychosocial constructs, sociodemographics, and previous health behaviors. RESULTS HPV vaccination uptake in both age cohorts (N = 2722) was associated with multiple variables, including but not limited to: provider recommendation (adjusted odds ratio [aOR], 11.63 [95% CI, 7.70-17.56] and aOR, 14.26 [95% CI, 9.52-21.38], for those aged 18 to 26 and 27 to 45 years, respectively) and positive HPV vaccine attitudes (aOR, 2.40 [95% CI, 1.70-3.40] and aOR, 1.46 [95% CI,1.06-2.02]). Among those who did not report or were unsure of prior HPV vaccination (N =1894), only 4.6% and 8.1% (aged 18-26 and 27-45 years, respectively) reported being very likely to receive the HPV vaccine in the next year. Increased intentions were associated with more positive vaccine attitudes (aOR, 2.45 [95% CI, 1.91-3.15] and aOR, 2.19 [95% CI, 1.72-2.78]) and provider recommendation (yes vs no; aOR, 1.97 [95% CI, 1.38-2.83] and aOR, 1.82 [95% CI, 1.31-2.52]; don't know/can't remember vs no; aOR, 1.38 [95% CI, 1.03-1.84] and aOR, 1.60 [95% CI, 1.17-2.18]). Sociodemographics and health behaviors associated with increased intentions differed for each age cohort. CONCLUSIONS Individual and interpersonal factors were associated with HPV vaccination uptake and intentions. Findings reveal the need for targeted interventions to improve HPV vaccination rates among these age groups.

Is tailored messaging more effective? An analysis of a digital health intervention to promote HPV vaccination intent among Latinx. J Behav Med 2022; 46:335-345.

Abstract
Latinx populations have unique barriers to HPV vaccination. In the current study, we assessed the effectiveness of an online intervention to increase HPV vaccination intentions among patients of clinics that principally serve a Latinx population (n = 85%) as part of a randomized control trial (RCT). Participants viewed on an iPad either an individually tailored educational website (CHiCOS) or untailored information derived from the Vaccine Information Sheet (VIS) for HPV. Vaccination intention and related covariates were assessed via survey items administered before (pre-test) and after (post-test) viewing the material. No statistically significant differences were seen in changes of intention to vaccinate between groups (N = 1294). However, 16% of all (tailored and untailored combined) participants increased in their intention to vaccinate, while 7% decreased in intention. Overall 72% of participants had high intentions to vaccinate, yet far fewer actually received a vaccine dose. The current study explores implications of the demonstrated intention-behavior gap. As such, it presents opportunities to improve future interventions-specifically those that employ tailored messaging.

Abstract
Human Papillomavirus (HPV) vaccine uptake among adolescents is influenced by their views and perceptions of the vaccination. The modified Carolina HPV Immunisation Attitudes and Beliefs Scale (CHIAS) is a well-established instrument to measure adolescents’ views of HPV vaccination. However, there is currently no Chinese version available to inform HPV vaccination promotion efforts among Chinese adolescents. This study aimed to translate and validate the Chinese version of the modified CHIAS (CHIAS-C). A cross-sectional descriptive study was carried out with 212 female adolescents recruited from secondary schools. Internal consistency, convergent validity, and construct validity were examined. Cronbach’s alpha of the five domains ranged from 0.60 to 0.89, suggesting acceptable internal consistency. Both positive and negative correlations were found between CHIAS-C domains and HPV vaccination intention, indicating convergent validity. Factorial validity was established through confirmatory factor analysis. Our findings suggest that adolescents had generally positive perceptions of HPV vaccination and were likely to accept vaccination if given more relevant information. It was found that most adolescents had neither attended any school talks about HPV nor spoken about the vaccination with healthcare providers. This illustrates that adolescents experience a lack of communication and education about HPV vaccination, both of which can be enhanced in order to persuade adolescents to receive the vaccination. The results suggest that the CHIAS-C is a reliable and valid tool to measure adolescents’ views of HPV vaccination. The translated scale may therefore be used in future adolescent research and to inform the development of interventions to increase HPV vaccine uptake.

Abstract
BACKGROUND Cervical cancer is a type of cancer caused by human papillomavirus (HPV). OBJECTIVE To determine the relationship between awareness of cervical cancer and HPV infection and attitudes towards HPV vaccine among women aged 15-49 years. DESIGN AND SETTING Cross-sectional study conducted at Karabük Training and Research Hospital, Turkey. METHODS 500 women who visited the gynecology outpatient clinic of a public hospital between July 15 and December 31, 2019, were selected through random sampling. Data were collected using a sociodemographic questionnaire comprising nine questions (created by the researchers), the HPV and Cervical Cancer Awareness Questionnaire and the Carolina HPV Immunization Attitudes and Beliefs Scale. RESULTS The relationship between the awareness questionnaire and the beliefs scale was explained through simple effect modeling of a structural equation. The women's knowledge score regarding cervical cancer and HPV infection was 4.69 ± 4.02 out of 15. Women were afraid of being diagnosed with cervical cancer and HPV infection, but they did not have sufficient information. They had poor information about the HPV vaccine, did not know how to obtain the vaccine and did not have enough information about its benefits and harmful effects. Women who were afraid of getting cervical cancer, and who thought that they were at risk, had more information about the HPV vaccine. CONCLUSION Women need information about cervical cancer, HPV infection and the HPV vaccine. Midwives, nurses and physicians who provide healthcare services in gynecological follow-ups should provide information to women about the HPV vaccine and cervical cancer.

Abstract
In India, cervical cancer associated with human papillomavirus (HPV) infection is a leading cause of cancer-related mortality among women. However, uptake of the vaccine in India is low. We assessed knowledge and attitudes towards HPV, assess participants' willingness to accept the vaccination for themselves and their children, and determine factors associated with intention to receive the HPV vaccine among women in Mangalore, India. This cross-sectional study surveyed a convenient sample of 237 women aged 18-45 years using a semi-structured questionnaire. All respondents reported being aware of HPV infection. However, 22.36% (n = 53) of the respondents have never heard about genital warts and 18.57% (n = 44) have never heard about HPV vaccine. Participants displayed good general knowledge of HPV infection (median score, 1.26; Interquartile Range (IQR): 1.04-1.52) and average knowledge of HPV vaccine (e.g., median score, 1.18; IQR: 0.73-1.45). HPV general knowledge and vaccine knowledge were associated with intention to receive the HPV vaccine and recommend it to children. Participant awareness of the HPV vaccine predicted vaccine intent for themselves. Participants' willingness to recommend the vaccine for their children was associated with older age, married status, having one or more children, and having a college education. Lack of awareness about genital warts was strongly associated with participants' refusal to get the HPV vaccine or recommend it for their own children (Relative Risk Ratio RRR: 12.21; 95% C.I.: 2.33-63.99). Our study validated the questionnaire as a reliable tool for assessing HPV and HPV vaccine knowledge, attitudes, awareness, and vaccine intentions in women aged 18-45 years. Public health education should focus on increasing awareness of genital warts as a sequela of HPV, as well as promote awareness of role and safety of HPV vaccination in -children.

Abstract
BACKGROUND To understand how human papillomavirus (HPV) screening results, HPV-related knowledge and attitudes are related to vaccination intention in three cost ranges and the actual vaccination behavior in a community sample of men who have sex with men (MSM). METHODS MSM aged 20 years of age or older were recruited between October 2015 and May 2016 from community health centers that provide HIV testing and consultation services in Southern Taiwan and on social media. MSM were seen at baseline and again at 6 months after baseline in a cohort study. The baseline study included 253 individuals; 182 of them returned for the 6th-month follow-up. At each visit, MSM were asked to receive HPV screening and filled out a questionnaire. Structural equation modeling was used to test whether attitudinal factors and HPV screening results from the baseline affect their self-reported actual vaccine uptake at the in 6th-month follow-up. RESULTS Our research included 171 participants from the cohort because they had full information of the study variables (mean ± SD age = 29.21 ± 6.18). Our model showed good model fit using indices such as the comparative fit index (value = 0.998) and root mean square error of approximation (value = 0.013). HPV knowledge can predict those who have intention to take up HPV vaccine no matter what the price (p = .02), and then predict vaccine uptake at the follow-up (p < .001). A positive HPV screening result can predict vaccine uptake at the follow-up (p = .004). CONCLUSION Our findings highlight the impact of vaccine price and HPV screening results on the intention and uptake of HPV vaccine. It is important to raise awareness of HPV in male populations. Clinicians and health educators should establish a safe and private environment for male patients for inquiring about HPV vaccine and HPV-related cancers.

Abstract
Narratives can have a powerful impact on our health-related beliefs, attitudes, and behaviors. The human papillomavirus (HPV) vaccine can protect against human papillomavirus that leads to different types of cancers. However, HPV vaccination rates are low. This study explored the effectiveness of a narrative-based interactive game about the HPV vaccines as a method to communicate knowledge and perhaps create behavioral outcomes. We developed a serious storytelling game called Vaccination Vacation inspired by personal narratives of individuals who were impacted by the HPV. We tested the game using a randomized control study of 99 adult participants and compared the HPV knowledge and vaccine beliefs of the Gamer Group (who played the game, n = 44) and the Reader group (who read a vaccine information sheet, n = 55). We also evaluated the usability of the game. In addition to high usability, the interactive game slightly impacted the beliefs about the HPV vaccine over standard delivery of vaccine information, especially among those who never received the HPV vaccine. We also observed some gender-based differences in perception towards usability and the likelihood of frequently playing the game. A narrative-based game could bring positive changes to players' HPV-related health beliefs. The combination of more comprehensive HPV vaccine information with the narratives may produce a larger impact. Narrative-based games can be effectively used in other vaccine education interventions and warrant future research.

Abstract
Human Papillomavirus (HPV) is the most common sexually transmitted infection (STI) in the United States. Despite numerous studies proving the safety and efficacy of the HPV vaccine, immunization rates remain low, especially among underserved populations. To identify factors contributing to low HPV vaccination rates, patients at a federally qualified health center in Kalamazoo MI were surveyed. Surveys were administered during routine patient visits to determine self-reported vaccination status and vaccination barriers. A total of 98 vaccine-eligible (males/females, ages 9-26 years old) patients/guardians completed the survey. In all, 46% of respondents completed the multi-dose vaccination course, and 56% of those identified as female. White patients reported higher vaccination rates (50%) than patients of color (45%). Of those vaccinated, the most common reason was "physician recommendation" (39%). Those not fully vaccinated most commonly reported being "too young" (39%). Importantly, individuals who had begun, but not completed, the vaccination course reported that their provider had not spoken to them about future vaccines in the series (74%). This study revealed disparities in vaccination rates between the sexes and racial groups, and emphasized the influential role of physician's recommendation on vaccination. Interestingly, other frequently cited barriers to vaccination-an association with sex, personal/religious beliefs, efficacy-proved to be insignificant barriers for this population. Instead, age-related misunderstandings and lack of consistent physician communication about vaccination provided significant barriers. Based on our results, education and reminders about the HPV vaccine by providers is a significant tool to maximize vaccination coverage.

Abstract
Human papillomavirus (HPV) is the most common sexually transmitted disease in the U.S. Data on knowledge, attitudes, and beliefs related to HPV vaccination among college students are limited. The purpose of this study was to provide a comprehensive description of the variables influencing HPV vaccination uptake and intention among college students. This study employed a cross sectional descriptive quantitative design. Survey data were collected online from the 181 college students, aged 18-25 years. The data were analyzed to identify the students' attitudes toward HPV vaccine (perceived potential harm, effectiveness, barriers, and uncertainty), knowledge of HPV and HPV vaccine, and their intention of receiving the vaccine in the next 6 months. Descriptive statistics, Chi-square tests, ANOVA, and logistic regressions were conducted to examine the correlates of vaccination intention and uptake. Among 181 participants, 101 (55.8%) were had received at least one dose of HPV vaccine, 52 (28.7%) intended to receive HPV vaccine, and 28 (15.5%) did not intend to receive HPV vaccine. On average, participants responded correctly to less than half of the questions on the HPV knowledge and HPV vaccine knowledge scales, and those who were vaccinated were significantly more knowledgeable than their counterparts. Multivariate logistic regression showed HPV vaccine knowledge and uncertainty were significant factors associated with HPV vaccine uptake. Providing education designed to improve HPV and HPV vaccination knowledge and decrease feelings of uncertainty could improve college students' HPV vaccination uptake.

Abstract
INTRODUCTION Evidence has consistently shown the high efficacy of human papillomavirus (HPV) vaccines in preventing cervical cancers. However, the HPV vaccine uptake rate in Hong Kong is very low. We will develop and evaluate an innovative, theory-based multidisciplinary team-led school-based HPV vaccination health-promotion program (MDL-SHPVP), engaging female adolescents, parents/guardians, and secondary school personnel in multicomponent educational strategies and interactive discussions. METHODS AND ANALYSIS A cluster randomized controlled trial is proposed. We will recruit 2520 female adolescents and their parents/guardians from 18 secondary day schools. The MDL-SHPVP is underpinned by the Health Belief Model and Precaution Adoption Process Model. Multicomponent interventions will be offered, including education sessions with small group dialogues with a registered nurse and trained healthcare and lay volunteers, and educational computer games. A team of volunteers will be established to raise HPV, cervical cancer, and HPV vaccine awareness. Outcomes include adolescents' uptake of the HPV vaccine, adolescents' intention to receive HPV vaccination, vaccine acceptance among parents/guardians, and parents'/guardians' and adolescents' HPV knowledge, attitudes, and beliefs. Data will be collected at baseline, 1 month, and 1 year after intervention. The generalized estimating equations analysis will be used for comparing the outcomes between the 2 groups. ETHICS AND DISSEMINATION Ethical approval was obtained from the Joint Chinese University of Hong Kong-New Territories East Cluster Clinical Research Ethics Committee (Ref. no.: 2019.055). We will disseminate the study findings via peer-reviewed publications and presentations at relevant events and international and local conferences.

Abstract
Purpose Cervical, oropharyngeal and anogenital cancers are vaccine-preventable diseases, but human papillomavirus (HPV) vaccination coverage in the US remains poor overall with regional variations in vaccination rates. We explore the acceptability by adolescents and their parents of HPV vaccination and text message reminders in the non-traditional setting of the emergency department (ED). Patients and Methods The modified validated Carolina HPV Attitudes and Beliefs Scale (CHIAS) survey was administered at two urban EDs to adolescents aged 13–18 years and their parents. Demographic information was collected for each participating adolescent. Recruitment occurred with consecutive eligible participants on the ED census list approached within 4-hour blocks from 8am to 8pm. Results Ninety-six adolescents completed the survey. The mean adolescent and parental knowledge scores were 63% (SD=29.7) and 60% (SD=22.1), respectively. The higher the HPV knowledge score among both adolescents and parents, the more likely they were to accept HPV vaccine in ED. Among the 10 cases where the parents disagreed to the HPV vaccine and the adolescents agreed to the HPV vaccine, the mean knowledge score among parents disagreeing was 47 compared to 62 among the remaining parents (p=0.04). Sixty-seven percent of adolescents and 68% of parents were agreeable to the adolescent receiving vaccination in the ED (kappa = 0.24). Seventy-five percent of adolescents and 71% of parents reported being agreeable to receiving text reminders for HPV vaccines (kappa = 0.20). Adolescent agreement with receiving a text message reminder corresponded with an increased willingness to be vaccinated (OR=3.21, 95% CI=1.07–9.57, p-value=0.0368). Sexually active adolescents were older (mean age, 17 years) than those who reported no sexual activity (mean age, 15 years) (p<0.0001). Conclusion Increased knowledge about HPV influences vaccine acceptance. Parents and adolescents may disagree in accepting HPV vaccination. A majority of adolescents and their parents were agreeable to receiving HPV vaccination in the ED and subsequent text message reminders. The ED should be explored further as a non-traditional healthcare setting for HPV vaccination of adolescents.

Abstract
The human papillomavirus (HPV) vaccine is the most effective way to prevent HPV-related cancers. Integrating provider vaccine counseling is crucial to improving HPV vaccine completion rates. Automating the counseling experience through a conversational agent could help improve HPV vaccine coverage and reduce the burden of vaccine counseling for providers. In a previous study, we tested a simulated conversational agent that provided HPV vaccine counseling for parents using the Wizard of OZ protocol. In the current study, we assessed the conversational agent among young college adults (n=24), a population that may have missed the HPV vaccine during their adolescence when vaccination is recommended. We also administered surveys for system and voice usability, and for health beliefs concerning the HPV vaccine. Participants perceived the agent to have high usability that is slightly better or equivalent to other voice interactive interfaces, and there is some evidence that the agent impacted their beliefs concerning the harms, uncertainty, and risk denials for the HPV vaccine. Overall, this study demonstrates the potential for conversational agents to be an impactful tool for health promotion endeavors.

Abstract
Few studies have assessed adolescent human papillomavirus (HPV) vaccine attitudes and whether they are associated with vaccination uptake. This study characterized HPV vaccine attitudes among male and female adolescents, identified factors associated with attitude changes, and examined associations between attitudes and vaccination receipt. Surveys were administered to adolescents aged 15-16 years who had not completed the HPV vaccine series. A modified version of the Carolina HPV Immunization Attitudes and Beliefs Scale (CHIAS) was employed to assess barriers, harms, ineffectiveness, and uncertainties scores. Surveys were available from 108 participants; 63% were male and 33% had initiated the HPV vaccine series at baseline. CHIAS scores significantly decreased (i.e., became more favorable) between baseline and follow-up for barriers (p = 0.01) and uncertainties (p < 0.01). At least one sociodemographic/clinical factor was associated with changes in each score. Attitude changes were not associated with receipt of HPV vaccine, although adolescents with higher baseline harms scores were significantly less likely to receive an HPV vaccine dose (OR = 0.67). Adolescents' HPV vaccine attitudes slightly improved over a one-year period during which an intervention was implemented. More research is needed to learn how parent and adolescent HPV vaccine attitudes form, and how best to address concerns about vaccine harms.

Abstract
Background Each year, human papillomavirus (HPV) causes 30,000 cancers in the USA despite the availability of effective and safe vaccines. Uptake of HPV vaccine has been low and lags behind other adolescent vaccines. This protocol describes a multilevel intervention to improve HPV vaccination rates. Methods Using a cluster randomized trial, we will evaluate the independent and combined impact of two evidence-based implementation strategies with innovative enhancements on HPV vaccination rates for female and male patients. The clusters are six primary care sites providing care to pediatric populations. We will use a stepped-wedge cluster randomized design, including process evaluation, to test the hypothesis that compared with the current course of care and a practice-level intervention using reminder-recall interventions coupled with provider-level audit and feedback with education increases HPV vaccination rates in exposed clusters. The factorial design allows us to use a single trial to test these two interventions and to assess each individually and in combination. Our design has four 12-month steps. The first step will be a baseline period; data collected during it will provide a within-practice control group for each cluster. Second, two clusters will be randomly assigned to receive intervention 1 (reminder and recall), and two clusters will be randomly selected to receive intervention 2 (audit and feedback with education). Third, the other two clusters will be randomly allocated to intervention 1 or 2. Clusters initially with intervention 1 will be randomly allocated to 1 + 2 or 1; clusters initially with intervention 2 will be randomly allocated to 1 + 2 or 2. Fourth, all clusters will receive both interventions. To ensure balance of patient numbers across interventions, we will use block randomization at the first step, with the six clusters grouped into three pairs according to volume. Our primary outcome will be vaccination rates. Discussion Results of our clinical trial and process evaluation will provide evidence showing whether practice- and provider-level interventions improve HPV vaccination rates and will offer insight into contextual factors associated with direction and magnitude of trial outcomes.

Abstract
BACKGROUND Anti-vaccination attitudes are important predictors of vaccination behavior. Existing measures of vaccination attitudes focus on specific age groups and/or particular vaccines; a more comprehensive measure would facilitate comparisons across studies. PURPOSE The aim of this study was to develop a short measure of general vaccination attitudes and establish its reliability and validity. METHODS Two studies were conducted using the VAX scale. For Study 1, participants were 409 individuals (53% female), with a mean age of 34.5 years. For Study 2, participants were 92 individuals (67% female) with a mean age of 28.6. Participants answered paper-and-pencil questions about their attitudes toward vaccines, prior and expected-future vaccination behaviors, perceived sensitivity to medicines, online behavior, and basic demographic information. Exploratory and confirmatory factor analyses were conducted with correlations and t tests then used to assess the scale's reliability and validity. RESULTS Four distinct but correlated vaccine attitudes were identified: (1) mistrust of vaccine benefit, (2) worries about unforeseen future effects, (3) concerns about commercial profiteering, and (4) preference for natural immunity. These factors were significantly related to prior vaccination behavior, future intentions to obtain recommended vaccinations, perceived sensitivity to medicines, and the tendency to obtain health information online. CONCLUSIONS The VAX scale provides an efficient method for identifying those with vaccination resistance, and the four subscales enable a more nuanced understanding of the nature of those views. It should be noted, however, that the strong correlations amongst the four subscales suggest that interventions should target all four attitude areas, and it remains to be seen whether differential emphasis across the four areas is warranted.

Abstract
INTRODUCTION The SAGE Working Group on Vaccine Hesitancy developed a vaccine hesitancy measure, the Vaccine Hesitancy Scale (VHS). This scale has the potential to aid in the advancement of research and immunization policy but has not yet been psychometrically evaluated. METHODS Using a cross-sectional design, we collected self-reported survey data from a large national sample of Canadian parents from August to September 2016. An online questionnaire was completed in English or French. We used exploratory and confirmatory factor analysis to identify latent constructs underlying parents' responses to 10 VHS items (response scale 1-5, with higher scores indicating greater hesitancy). In addition to the VHS, measures included socio-demographics items, vaccine attitudes, parents' human papillomavirus (HPV) vaccine decision-making stage, and vaccine refusal. RESULTS A total of 3779 Canadian parents completed the survey in English (74.1%) or French (25.9%). Exploratory and confirmatory factor analysis revealed a two-factor structure best explained the data, consisting of 'lack of confidence' (M = 1.98, SD = 0.72) and 'risks' (M = 3.07, SD = 0.95). Significant Pearson correlations were found between the scales and related vaccine attitudes. ANOVA analyses found significant differences in the VHS sub-scales by parents' vaccine decision-making stages (p < .001). Independent samples t-tests found that the VHS sub-scales were associated with HPV vaccine refusal and refusing another vaccine (p < .001). Socio-demographic differences in the VHS were found; however, effect sizes were small (η2 < 0.02). CONCLUSIONS The VHS was found to have two factors that have construct and criterion validity in identifying vaccine hesitant parents. A limitation of the VHS was few items that loaded on the 'risks' component and a lack of positively and negatively worded items for both components. Based on these results, we suggest modifying the wording of some items and adding items on risk perceptions.

Abstract
BACKGROUND Parents' human papillomavirus (HPV) vaccination decision-making is strongly influenced by their attitudes and beliefs toward vaccination. To date, psychometrically evaluated HPV vaccination attitudes scales have been narrow in their range of measured beliefs and often limited to attitudes surrounding female HPV vaccination. The study aimed to develop a comprehensive, validated and reliable HPV vaccination attitudes and beliefs scale among parents of boys. METHODS Data were collected from Canadian parents of 9- to 16-year-old boys using an online questionnaire completed in 2 waves with a 7-month interval. Based on existing vaccination attitudes scales, a set of 61 attitude and belief items were developed. Exploratory and confirmatory factor analyses were conducted. Internal consistency was evaluated with Cronbach's α and stability over time with intraclass correlations. RESULTS The HPV Attitudes and Beliefs Scale (HABS) was informed by 3117 responses at time 1 and 1427 at time 2. The HABS contains 46 items organized in 9 factors: Benefits (10 items), Threat (3 items), Influence (8 items), Harms (6 items), Risk (3 items), Affordability (3 items), Communication (5 items), Accessibility (4 items), and General Vaccination Attitudes (4 items). Model fit at time 2 were: χ/df = 3.13, standardized root mean square residual = 0.056, root mean square error approximation (confidence interval) = 0.039 (0.037-0.04), comparative fit index = 0.962 and Tucker-Lewis index = 0.957. Cronbach's αs were greater than 0.8 and intraclass correlations of factors were greater than 0.6. CONCLUSIONS The HABS is the first psychometrically-tested scale of HPV attitude and beliefs among parents of boys available for use in English and French. Further testing among parents of girls and young adults and assessing predictive validity are warranted.

Abstract
Any sexually active person has the possibility of contracting the human papillomavirus (HPV) sometime in their lifetime. HPV vaccines are effective in preventing HPV if obtained prior to viral exposure. Research on knowledge and beliefs of HPV and HPV vaccination among college students in Vietnam is significantly scarce. The purpose of this study is to examine the knowledge and beliefs about HPV among college students in Vietnam compared to college students in the US. This cross-cultural comparison will fill a void in current research on this subject. Over 900 college students (N=932: n=495 in Vietnam and n=437 in the US) participated in a self-administered survey on the knowledge and beliefs about HPV in September and October 2016. Vietnamese participants reported lower levels of knowledge and experiences with the HPV virus and vaccines (p<0.01). Additionally, Vietnamese participants also exhibited more barriers in obtaining the vaccination, as well as, HPV risk denial (p<0.01). The level of knowledge is an important predictor of barriers (p<0.01; ηp2=0.022) and risk denial (p<0.01; ηp2=0.116). On average, both Vietnamese and US participants could correctly answer less than half of the survey questions regarding HPV knowledge. Additionally, provider recommendations are potentially more important than informal connections (e.g. friends, family) to reduce barriers to HPV vaccination (p<0.01; ηp2=0.035) and denial of HPV risks (p<0.05; ηp2=0.008). The increase of knowledge about HPV prevention, including and vaccination, has the potential to be improved through provider interventions. Vietnam could take action toward promoting HPV vaccinations not only at an individual level but also at a national or local level. Further research may examine the effects of a lack of knowledge on HPV-related health outcomes.
