Coronavirus disease 2019 (COVID-19) was declared a pandemic in March 2020. Several prophylactic vaccines against COVID-19 are currently in development, yet little is known about people's acceptability of a COVID-19 vaccine. We conducted an online survey of adults ages 18 and older in the United States (n = 2,006) in May 2020. Multivariable relative risk regression identified correlates of participants' willingness to get a COVID-19 vaccine (i.e. , vaccine acceptability). Overall, 69% of participants were willing to get a COVID-19 vaccine. Participants were more likely to be willing to get vaccinated if they thought their healthcare provider would recommend vaccination (RR = 1.73, 95% CI: 1.49–2.02) or if they were moderate (RR = 1.09, 95% CI: 1.02–1.16) or liberal (RR = 1.14, 95% CI: 1.07–1.22) in their political leaning. Participants were also more likely to be willing to get vaccinated if they reported higher levels of perceived likelihood getting a COVID-19 infection in the future (RR = 1.05, 95% CI: 1.01–1.09), perceived severity of COVID-19 infection (RR = 1.08, 95% CI: 1.04–1.11), or perceived effectiveness of a COVID-19 vaccine (RR = 1.46, 95% CI: 1.40–1.52). Participants were less likely to be willing to get vaccinated if they were non-Latinx black (RR = 0.81, 95% CI: 0.74–0.90) or reported a higher level of perceived potential vaccine harms (RR = 0.95, 95% CI: 0.92–0.98). Many adults are willing to get a COVID-19 vaccine, though acceptability should be monitored as vaccine development continues. Our findings can help guide future efforts to increase COVID-19 vaccine acceptability (and uptake if a vaccine becomes available). [ABSTRACT FROM AUTHOR]

Sexual minority women (lesbian, bisexual, and other women who have sex with women) are at risk for human papillomavirus (HPV) infection and HPV-related disease, demonstrating the importance of HPV vaccination for these women. We conducted an online survey of sexual minority women ages 18–45 from the United States (n = 505) in October 2019, about two months after HPV vaccine recommendations were expanded to include ages 27–45. Multivariable Poisson regression identified correlates of HPV vaccine initiation (i.e., receipt of at least one HPV vaccine dose). Overall, 65% of participants ages 18–26 and 33% of participants ages 27–45 had initiated the HPV vaccine series. Among participants ages 18–26, initiation was more common among those who had received a healthcare provider recommendation (RR = 2.19, 95% CI: 1.64–2.93) or had disclosed their sexual orientation to their primary healthcare provider (RR = 1.33, 95% CI: 1.07–1.65). Among initiators ages 27–45, a large majority (89%) reported receiving their first dose before turning age 27. Initiation was more common among participants ages 27–45 who had received a healthcare provider recommendation (RR = 3.23, 95% CI: 2.31–4.53) or who reported greater perceived social support for HPV vaccination (RR = 1.22, 95% CI: 1.05–1.40). Several reasons for not yet getting HPV vaccine differed by age group (ages 18–26 vs. ages 27–45; all p < 0.05). Many sexual minority women, particularly those ages 27–45, remain unvaccinated against HPV. Findings provide early insight into HPV vaccine coverage among adult women and highlight key leverage points for increasing vaccination among this population. [ABSTRACT FROM AUTHOR]

Genetic counseling and testing have an important role in the care of patients at elevated risk for breast cancer. However, conventional pre- and post-test genetic counseling is labor and time intensive, less accessible for patients living outside major urban centers, and impractical on a large scale. A patient-driven approach to genetic counseling and testing may increase access, improve patients' experiences, affect efficiency of clinical practice, and help meet workforce demand. The objective of this 2-arm randomized controlled trial is to determine the efficacy of Know Your Risk (KYR), a genetic counseling patient preference intervention. Females (n = 1000) at elevated risk (>20% lifetime) for breast cancer will be randomized to the KYR intervention or conventional genetic counseling. The study will provide comprehensive assessment of breast cancer risk by multigene panel testing and validated polygenic risk score. Primary outcome is adherence to National Comprehensive Cancer Network guidelines for a clinical encounter every 6–12 months and an annual mammogram (breast MRI if recommended) determined by medical record review. Secondary outcomes include adherence to other recommended cancer screening tests determined by medical record review and changes in breast cancer knowledge, perception of risk, post-test/counseling distress, and satisfaction with counseling by completion of three surveys during the study. Study aims will be evaluated for non-inferiority of the KYR intervention compared to conventional genetic counseling. If efficacious, the KYR intervention has the potential to improve patients' experience and may change how genetic counseling is delivered, inform best practices, and reduce workforce burden.

Introduction: Concomitant (same-day) delivery of two or more vaccines to adolescents is effective, safe, and efficient. Increasing concomitant vaccination could improve coverage for recommended adolescent vaccines, but little is known about who receives vaccines concomitantly.Methods: Data came from healthcare provider-verified records on 70,144 adolescents (aged 13-17 years) in the 2008-2012 versions of the National Immunization Survey-Teen who had received at least one dose of tetanus, diphtheria, and acellular pertussis (Tdap) booster; meningococcal conjugate vaccine (MenACWY); or human papillomavirus (HPV) vaccine. Separately for each vaccine, multivariable logistic regression identified adolescent and household correlates of concomitant versus single vaccination, stratified by adolescent sex. Vaccination took place in 2007-2012, data collection in 2008-2012, and data analysis in 2015.Results: Among vaccinated adolescents, 51%-65% of girls and 25%-53% of boys received two vaccines concomitantly. Concomitant uptake of each vaccine increased over survey years (e.g., 2012 vs 2008: girls' Tdap booster, OR=1.88, 95% CI=1.56, 2.26; boys' Tdap booster, OR=2.62, 95% CI=2.16, 3.16), with the exception of HPV vaccination among boys. Additionally, concomitant vaccination was less common as adolescents got older and in the Northeast (all p<0.05). For MenACWY and HPV vaccine, concomitant uptake was less common for girls whose mothers had higher versus lower education and for boys who lived in metropolitan versus non-metropolitan areas (all p<0.05).Conclusions: Missed opportunities for concomitant adolescent vaccination persist, particularly for HPV vaccine. Future interventions targeting groups with low rates of concomitant vaccination could improve population-level coverage with recommended vaccines. [ABSTRACT FROM AUTHOR]

Rationale Recommendations from healthcare providers are one of the most consistent correlates of adolescent vaccination, but few studies have investigated other elements of patient-provider communication and their relevance to uptake. Objective We examined competing hypotheses about the relationship of patient-driven versus provider-driven communication styles with vaccination. Methods We gathered information about vaccine uptake from healthcare provider-verified data in the 2010 National Immunization Survey-Teen for tetanus, diphtheria, and pertussis (Tdap) booster, meningococcal vaccine, and human papillomavirus (HPV) vaccine (initiation among females) for adolescents ages 13–17. We categorized communication style in parents' conversations with healthcare providers about vaccines, based on parents' reports (of whether a provider recommended a vaccine and, if so, if conversations were informed, shared, or efficient) ( N = 9021). Results Most parents reported either no provider recommendation (Tdap booster: 35%; meningococcal vaccine: 46%; and HPV vaccine: 31%) or reported a provider recommendation and shared patient-provider communication (43%, 38%, and 49%, respectively). Provider recommendations were associated with increased odds of vaccination (all p s < 0.001). In addition, more provider-driven communication styles were associated with higher rates of uptake for meningococcal vaccine (efficient style: 82% vs. shared style: 77% vs. informed style: 68%; p < 0.001 for shared vs. informed) and HPV vaccine (efficient style: 90% vs. shared style: 70% vs. informed style: 33%; p < 0.05 for all comparisons). Conclusion Efficient communication styles were used rarely (≤2% across vaccines) but were highly effective for encouraging meningococcal and HPV vaccination. Intervention studies are needed to confirm that efficient communication approaches increase HPV vaccination among adolescents. [ABSTRACT FROM AUTHOR]

Background Many youth with special health care needs (YSHCN) have not received recommended adolescent vaccines, yet data are lacking on correlates of vaccination among this population. Such information can identify subgroups of YSHCN that may be at risk for under-immunization and strategies for increasing vaccination. Methods We analyzed weighted data from a population-based sample of parents with an 11- to 17-year-old child with a special health care need from the 2010–2012 North Carolina Child Health Assessment and Monitoring Program ( n = 604). We used ordinal logistic regression to identify correlates of how many recommended vaccines (tetanus booster, meningococcal, and HPV [at least one dose] vaccines) adolescents had received. Results Only 12% of YSHCN (18% of females and 7% of males) had received all three vaccines. More YSHCN had received tetanus booster vaccine (91%) than meningococcal (28%) or HPV vaccines (32%). In multivariable analyses, YSHCN who were female (OR = 2.59, 95% CI: 1.57–4.24), ages 16–17 (OR = 2.06, 95% CI: 1.10–3.87), or who had a preventive check-up in the past year (OR = 2.98, 95% CI: 1.24–7.21) had received a greater number of the vaccines. YSHCN from households that contained a person with at least some college education had received fewer of the vaccines (OR = 0.57, 95% CI: 0.33–0.96). Vaccine coverage did not differ by type of special health care need. Conclusions Vaccine coverage among YSHCN is lacking and particularly low among those who are younger or male. Reducing missed opportunities for vaccination at medical visits and concomitant administration of adolescent vaccines may help increase vaccine coverage among YSHCN. [ABSTRACT FROM AUTHOR]

Abstract: Purpose: Schools are increasingly a part of vaccine provision, because of laws mandating provision of information by schools about vaccination, school entry requirements, and mass vaccination campaigns. We examined preferences for programmatic aspects of voluntary school mass vaccination programs (i.e., “vaccination days”). Methods: We analyzed data from a national sample of United States parents of adolescent males ages 11–19 years (n = 308) and their sons (n = 216), who completed an online survey in November 2011. Results: Sons believed that adolescents should be able to get vaccinated without parental consent at a younger age than parents did (p < .001) and were more willing to participate in vaccination days without a parent present (p = .04). Parents perceived school vaccination days to be a more convenient way to get their sons recommended vaccines if they were younger parents, had older adolescent sons, supported laws letting schools share vaccination records with health care providers, or had sons who were previously immunized at school (all p < .05). Parents of older sons were less likely to want their sons' vaccination records sent home (odds ratio [OR] = .47; 95% confidence interval [CI], .29–.77) or to their sons' physicians (OR = .61; 95% CI, .37–.98) compared with parents of younger sons, but more likely to prefer their sons' records be entered in an immunization registry (OR = 1.66; 95% CI, 1.05–2.63). Conclusions: Sons' age had an important role in support for vaccination days and preferences for sharing vaccination information with health care professionals. Parents and sons had similar beliefs about vaccination in schools, but the sons' responses suggested an interest in greater autonomy. [Copyright &y& Elsevier]

Abstract: Limited research has examined HPV vaccination in Appalachia, a region with cervical cancer disparities. We analyzed 2008–2010 National Immunization Survey-Teen data for adolescent females ages 13–17 from Appalachia (n =1951) to identify correlates of HPV vaccination and reasons why their parents do not intend to vaccinate. HPV vaccine initiation was 40.8%, completion was 27.7%, and follow-through was 67.8%. Vaccination outcomes tended to be higher among females who were older, had visited their healthcare provider in the last year, or whose parents reported receiving a provider recommendation to vaccinate. Only 41.0% of parents with unvaccinated daughters intended to vaccinate in the next year. The most common reasons for not intending to vaccinate were believing vaccination is not needed or not necessary (21.5%) and lack of knowledge (18.5%). Efforts to reduce missed opportunities for vaccination at healthcare visits and address reasons why parents are not vaccinating may help increase HPV vaccination in Appalachia [Copyright &y& Elsevier]

Highlights: [•] HPV vaccination is low among adolescent males, with less than 10% vaccinated. [•] Healthcare provider recommendation is key to increasing HPV vaccination among males. [•] Continued efforts are needed to monitor HPV vaccination among males. [ABSTRACT FROM AUTHOR]

Abstract: Purpose: Electronic cigarettes (e-cigarettes) are a new type of device that delivers vaporized nicotine without the tobacco combustion of regular cigarettes. We sought to understand awareness of and willingness to try e-cigarettes among adolescent males, a group that is at risk for smoking initiation and may use e-cigarettes as a “gateway” to smoking. Methods: A national sample of 11–19-year-old males (n = 228) completed an online survey in November 2011. We recruited participants through their parents, who were members of a panel of U.S. households constructed using random-digit dialing and addressed-based sampling. Results: Only two participants (< 1%) had previously tried e-cigarettes. Among those who had not tried e-cigarettes, most (67%) had heard of them. Awareness was higher among older and non-Hispanic adolescents. Nearly 1 in 5 (18%) participants were willing to try either a plain or flavored e-cigarette, but willingness to try plain versus flavored varieties did not differ. Smokers were more willing to try any e-cigarette than nonsmokers (74% vs. 13%; OR 10.25, 95% CI 2.88, 36.46). Nonsmokers who had more negative beliefs about the typical smoker were less willing to try e-cigarettes (OR .58, 95% CI .43, .79). Conclusions: Most adolescent males were aware of e-cigarettes, and a substantial minority were willing to try them. Given that even experimentation with e-cigarettes could lead to nicotine dependence and subsequent use of other tobacco products, regulatory and behavioral interventions are needed to prevent “gateway” use by adolescent nonsmokers. Campaigns promoting negative images of smokers or FDA bans on sales to youth may help deter use. [Copyright &y& Elsevier]

Abstract: Objective: To evaluate a brief intervention to increase provision of adolescent vaccines at health centers that reach the medically underserved. Method: In April 2010, clinical coordinators from 17 federally qualified health centers (serving 7827 patients ages 12–17) participated in a competition to increase uptake of recommended adolescent vaccines: tetanus, diphtheria, and pertussis booster; meningococcal conjugate; and human papillomavirus. Vaccination coordinators attended a webinar that reviewed provider-based changes recommended by the CDC''s Assessment, Feedback, Incentives, and eXchanges (AFIX) program and received weekly follow-up emails. Data on vaccine uptake came from the North Carolina Immunization Registry. Results: Uptake of targeted adolescent vaccines increased during the one-month intervention period by about 1–2% (all p <.05). These small but reliable increases were greater than those observed for non-targeted vaccines (measles, mumps, and rubella; hepatitis B; and varicella). Conclusion: This AFIX webinar led to small increases in provision of targeted adolescent vaccines over a one-month period. Similar, sustainable programs at healthcare facilities, including federally qualified health centers that function as safety net providers for medically underserved populations could help reach populations with great need.

Abstract: Purpose: We examined parents'' and adolescents'' preferences regarding potential strategies to increase human papillomavirus (HPV) vaccination rates, including offering the vaccine in alternative settings, concomitant administration of vaccines, and optimizing the structure of vaccination medical visits. Methods: A national sample of U.S. parents of adolescent boys aged 11–17 years (n = 506) and their sons (n = 391) completed online surveys in August and September 2010. We used analysis of variance for mixed designs to examine preferences for vaccination settings. Results: Parents and sons were most comfortable with sons receiving HPV vaccine in a doctor''s office. Parents of sons who had not visited their regular health care providers in the past year were more comfortable with sons receiving HPV vaccine at a public clinic (p < .001) or school (p < .05) compared with parents whose sons had recent visits. Results from the son survey showed a similar pattern. Parents and sons reported moderate levels of acceptability of concomitant administration. They most preferred to have the three HPV vaccine shots administered during brief nurse visits. Conclusions: Offering HPV vaccine in alternative settings and administering it with other recommended adolescent vaccines may increase uptake among adolescent boys. Parents and sons may prefer HPV vaccines be administered during brief nurse visits. [ABSTRACT FROM AUTHOR]

Abstract: Purpose: The Internet is an increasingly common source of health-related information. We sought to examine associations between parents’ Internet information-seeking and their knowledge, attitudes and beliefs about human papillomavirus (HPV) vaccine. Methods: We interviewed parents within a year after approval of HPV vaccine for females and males. Participants were North Carolina parents with daughters ages 10–18 surveyed by telephone in Fall 2007 (n =773); and a national sample of parents with sons ages 11–17 surveyed online in Fall 2010 (n =115). We used multivariate regression to examine associations of past and intended Internet seeking for HPV vaccine information with knowledge and health belief model-related constructs. Results: Among parents of daughters, having heard of HPV vaccine through the Internet (8%) was associated with higher HPV knowledge, perceived likelihood of HPV, and vaccination willingness, and with receiving a doctor''s recommendation. It was also associated with lower perceived vaccine harms, uncertainty, and anticipated regret. Parents of sons who heard of HPV vaccine through the Internet (10%) perceived greater barriers to vaccination than parents who learned about HPV vaccine for males through other sources. Intended future Internet information-seeking among parents of daughters (69%) was more likely if they perceived a lower likelihood that their daughters would get HPV if they were vaccinated (all p <.05). Conclusions: Our findings suggest a positive influence of accessing information on the Internet about HPV vaccine. It was associated with higher knowledge and mostly positive parental attitudes and beliefs. [Copyright &y& Elsevier]

Abstract: In 2009, the United States approved quadrivalent HPV vaccine for males 9–26 years old, but data on vaccine uptake are lacking. We determined HPV vaccine uptake among adolescent males, as well as stage of adoption and vaccine acceptability to parents and their sons. A national sample of parents of adolescent males ages 11–17 years (n =547) and their sons (n =421) completed online surveys during August and September 2010. Analyses used multivariate linear regression. Few sons (2%) had received any doses of HPV vaccine, and most parents and sons were unaware the vaccine can be given to males. Parents with unvaccinated sons were moderately willing to get their sons free HPV vaccine (mean=3.37, SD=1.21, possible range 1–5). Parents were more willing to get their sons vaccinated if they perceived higher levels of HPV vaccine effectiveness (β =0.20) or if they anticipated higher regret about their sons not getting vaccinated and later developing an HPV infection (β =0.32). Vaccine acceptability was also modest among unvaccinated sons (mean=2.98, SD=1.13, possible range 1–5). Sons were more willing to get vaccinated if they perceived higher peer acceptance of HPV vaccine (β =0.39) or anticipated higher regret about not getting vaccinated and later developing an HPV infection (β =0.22). HPV vaccine uptake was nearly nonexistent a year after permissive national recommendations were first issued for males. Vaccine acceptability was moderate among both parents and sons. Efforts to increase vaccine uptake among adolescent males should consider the important role of peer acceptance and anticipated regret. [Copyright &y& Elsevier]

Abstract: Purpose: Parent–child conversations about human papillomavirus (HPV) vaccine may provide parents with the opportunity to talk with their daughters about sexual health. We sought to characterize mothers'' communication with their adolescent daughters about HPV vaccine. Methods: We surveyed 609 mothers of girls aged between 11 and 20 years living in North Carolina in Fall 2008. We used logistic regression to identify the correlates of mother–daughter communication. Results: Most mothers (81%) reported having discussed HPV vaccine with their daughters. For almost half of these families (47%), discussion of HPV vaccine led to a conversation about sex. This was more common among mothers who believed that their daughters may be sexually active (odds ratio [OR]: 1.88; 95% confidence interval [CI]: 1.25–2.83), had greater knowledge of HPV vaccine (OR: 2.46; 95% CI: 1.07–5.64), lived in urban areas (OR: 1.75; 95% CI: 1.21–2.54), or reported being born-again Christians (OR: 1.74; 95% CI: 1.17–2.58). Most mothers who talked with their daughters about HPV vaccine reported having discussed the reasons for and against getting vaccinated (86%). Mothers most commonly reported having discussed the potential HPV vaccine benefits, usually protection against cervical cancer (56%), and less frequently reported having discussed the perceived disadvantages of HPV vaccine. Conclusions: HPV vaccine conversations may provide opportunities for sexual health promotion and sexually transmitted infection (STI) prevention. [ABSTRACT FROM AUTHOR]

Abstract: Purpose: To examine correlates of human papillomavirus (HPV) vaccine awareness and information sources in a state requiring schools to inform parents about HPV vaccine. Methods: Telephone survey of a North Carolina population-based sample of 696 parents of females aged 10–17 years about HPV vaccine awareness and information sources (daughters'' schools, healthcare provider, drug company advertisements, news stories) was conducted. Results: Overall, 91% of parents had heard of HPV vaccine. Parents were more likely to be aware if they had household incomes of $50,000 or higher, were women, had non-Hispanic white daughters, or had daughters vaccinated against meningitis. Information sources included drug company advertisements (64%), healthcare providers (50%), news stories (50%), and schools (9%). Only parents who heard from their children''s healthcare providers were more likely to initiate HPV vaccine for their daughters. Conclusions: Parents had rarely heard of the vaccine through schools. The only source associated with vaccine initiation was hearing from a healthcare provider. [Copyright &y& Elsevier]

Abstract: We examined mothers’ willingness to get their adolescent sons HPV vaccine. In December 2009, 2 months after approval of HPV vaccine for males, we surveyed a national sample of mothers with sons aged 9–18 (n =406). More mothers were definitely or probably willing to get their sons HPV vaccine if the vaccine were free (47%) than if it cost $400 out of pocket (11%). The importance of HPV vaccine possibly protecting their sons’ future female partners from HPV-related disease was the strongest correlate of willingness. These findings are important to increasing acceptability to parents of HPV vaccine for their sons. [ABSTRACT FROM AUTHOR]

Abstract: We examined the prevalence of reported pain following human papillomavirus (HPV) vaccination and whether it differed from that for other adolescent vaccines or affected completion of the HPV vaccine regimen. In 2008, we conducted cross-sectional surveys with parents of adolescent girls aged 11–20 living in areas of North Carolina with elevated cervical cancer rates who had received at least one dose of HPV vaccine. Pain from HPV vaccination, while commonly reported by parents, was less frequent compared to other adolescent vaccines and did not appear to affect vaccine regimen completion. These findings may be important to increase HPV vaccination coverage. [Copyright &y& Elsevier]

Abstract: Though many studies have documented correlates of HPV vaccine acceptability, our study is one of the first to examine correlates of vaccine initiation. The current study aimed to identify modifiable correlates of HPV vaccine initiation among adolescent girls in high risk communities and whether correlates varied by race and urban/rural status. In 2007, we conducted a cross-sectional survey of 889 parents of adolescent girls aged 10–18 living in areas of North Carolina, USA with high cervical cancer rates. We analyzed data using logistic regression. Health Belief Model constructs were associated with HPV vaccine initiation in multivariate analyses, including doctor''s recommendation to get HPV vaccine, perceived barriers to obtaining HPV vaccine, and perceived potential vaccine harms. While exploratory stratified analyses suggested that many of the same parent beliefs were important correlates of HPV vaccine initiation regardless of racial group or urban/rural status, a few differences did exist. These potentially modifiable beliefs offer well-defined targets for future interventions designed to increase HPV vaccine coverage. However, the beliefs'' relative importance may differ between racial groups and regions. [Copyright &y& Elsevier]

Abstract: To assess HPV vaccine acceptability, focus groups of women (18–26 years), parents, community leaders, and healthcare providers were conducted throughout Ohio Appalachia. Themes that emerged among the 23 focus groups (n =114) about the HPV vaccine were: barriers (general health and vaccine specific), lack of knowledge (cervical cancer and HPV), cultural attitudes, and suggestions for educational materials and programs. Important Appalachian attitudes included strong family ties, privacy, conservative views, and lack of trust of outsiders to the region. There are differences in HPV vaccine acceptability among different types of community members highlighting the need for a range of HPV vaccine educational materials/programs to be developed that are inclusive of the Appalachian culture.

Abstract: Telephone interviews of health department personnel in six states and review of an immunization database from one state were conducted to assess human papillomavirus (HPV) vaccine availability, recommendations, cost, policies, and educational materials in health departments in seven Appalachian states. Most (99.1%) health departments (n =234) reported receiving patient requests for the HPV vaccine, and only two (1%) health departments reported that they did not provide the vaccine for patients. HPV vaccine supply was reported to not meet the demand in 10.5% (24/228) of health departments due to high costs. Level (state, region, county) at which policy about the HPV vaccine was determined, vaccine recommendations, costs, and available educational materials varied among states. This study documented variation in vaccine availability, recommendations, cost, policies, and educational materials in Appalachian health departments that could significantly affect vaccine distribution. Findings highlight the need for more comprehensive and consistent policies that maximize accessibility of the HPV vaccine to women, especially those in underserved areas. [Copyright &y& Elsevier]

Purpose The success of national immunization programs depends on the public's confidence in vaccines. We sought to develop a scale for measuring confidence about adolescent vaccination in diverse populations of parents. Methods Data came from 9623 parents who completed the 2010 National Immunization Survey-Teen, an annual, population-based telephone survey. Parents reported on a 13- to 17-year-old child in their households. We used exploratory and confirmatory factor analysis to identify latent constructs underlying parents’ responses to 8 vaccination belief survey items (response scale 0–10) conceptualized using the Health Belief Model. We assessed the scale's psychometric properties overall and across demographic subgroups. Results Parents’ confidence about adolescent vaccination was generally high. Analyses provided support for three factors assessing benefits of vaccination (mean = 8.5), harms of vaccination (mean = 3.3), and trust in healthcare providers (mean = 9.0). The model showed good fit both overall (comparative fit index = 0.97) and across demographic subgroups, although internal consistency was variable for the three factors. We found lower confidence among several potentially vulnerable subpopulations, including mothers with lower levels of education and parents whose children were of Hispanic ethnicity (both p < 0.05). Conclusions Our brief, three-factor scale offers an efficient way to measure confidence in adolescent vaccination across demographic subgroups. Given evidence of lower confidence by educational attainment and race/ethnicity, program planners should consider factors such as health literacy and cultural competence when designing interventions to promote adolescent vaccination to ensure these programs are fully accessible.

Highlights • We tested a web-based HPV vaccination intervention for young gay and bisexual men. • Findings demonstrate positive effects on HPV vaccination attitudes and beliefs. • The intervention was highly acceptable to participants. Abstract Background Effective interventions to promote human papillomavirus (HPV) vaccination are needed, particularly among populations at increased risk of HPV-related disease. We developed and pilot tested a web-based intervention, Outsmart HPV, to promote HPV vaccination among young gay and bisexual men (YGBM). Methods In 2016, we recruited a national sample (n = 150) of YGBM ages 18–25 in the United States who had not received any doses of HPV vaccine. Participants were randomized to receive either standard HPV vaccination information (control) or population-targeted, individually-tailored content (Outsmart HPV intervention). We assessed between group differences in HPV vaccination attitudes and beliefs immediately following the intervention using multiple linear regression. Results There were no differences in HPV vaccination attitudes, beliefs and intentions between groups at baseline. Compared to participants in the control group, intervention participants reported: greater perception that men who have sex with men are at higher risk for anal cancer relative to other men (b = 0.34); greater HPV vaccination self-efficacy (b = 0.15); and fewer perceived harms of HPV vaccine (b = −0.34) on posttest surveys (all p <.05). Overall, intervention participants reported high levels of acceptability and satisfaction with the Outsmart HPV intervention (all > 4.4 on a 5-point scale). Conclusions Findings from this study provide preliminary support for a brief, tailored web-based intervention in improving HPV vaccination attitudes and beliefs among YGBM. An important next step is to determine the effects of Outsmart HPV on HPV vaccine uptake. Clinical trials registration ClinicalTrials.gov identifier NCT02835755. [ABSTRACT FROM AUTHOR]

Abstract: Background: Patient navigation (PN) is a system-level strategy to decrease cancer mortality rates by reducing barriers to cancer care. Barriers to resolution among participants in the PN intervention arm with a breast or cervical abnormality in the Patient Navigation Research Program and navigators' actions to address those barriers were examined. Methods: Data from seven institutions (2005–2010) included 1,995 breast and 1,194 cervical patients. A stratified Cox proportional hazards regression model was used to examine the effects of barriers on time to resolution of an abnormal screening test or clinical finding. Findings: The range of unique barriers was 0 to 12 and 0 to 7 among participants with breast and cervical abnormalities, respectively. About two thirds of breast and one half of cervical participants had at least one barrier resulting in longer time to diagnostic resolution among breast (adjusted hazard ratio [HR], 0.744; p < .001) and cervical (adjusted HR, 0.792; p < .001) participants. Patient- and system-level barriers were most common. Frequent navigator actions were making arrangements, scheduling appointments, referrals, and education. Conclusions: Having a barrier resulted in a delay in diagnostic resolution of an abnormal screening test or clinical finding. Health care systems can use these findings to improve existing PN programs or when developing new programs. [Copyright &y& Elsevier]

Background Human papillomavirus (HPV) infection and associated cervical disease are common among all women, regardless of sexual identity, yet limited research has examined HPV vaccination among lesbian and bisexual women. Methods A national sample of lesbian and bisexual women ages 18-26 (n = 543) completed our online survey during Fall 2013. We used multivariable logistic regression to identify correlates of HPV vaccine initiation (receipt of at least 1 dose) and completion (receipt of all 3 recommended doses among initiators). Results Overall, 45% of respondents had initiated HPV vaccine and 70% of initiators reported completing the series. HPV vaccine initiation was higher among respondents who were students, had received a healthcare provider's recommendation, perceived greater positive social vaccination norms, or anticipated greater regret if they did not get vaccinated and later got HPV. Initiation was lower among those who perceived greater HPV vaccine harms or greater barriers to getting the vaccine (all p < .05). HPV vaccine completion was higher among initiators who had a college degree while it was lower among those who perceived a greater likelihood of acquiring HPV or who anticipated greater regret if they got the vaccine and fainted (all p < .05). Among HPV vaccine initiators who had not yet completed the series, about half (47%) intended to get the remaining doses. Conclusions Many lesbian and bisexual women are not getting vaccinated against HPV. Healthcare provider recommendations and women's health beliefs may be important leverage points for increasing vaccination among this population. [ABSTRACT FROM AUTHOR]

Abstract: HPV vaccination rates among adolescents in the United States lag behind some other developed countries, many of which routinely offer the vaccine in schools. We sought to assess mothers’ willingness to have their adolescent daughters receive HPV vaccine at school. A national sample of mothers of adolescent females ages 11–14 completed our internet survey (response rate=66%). The final sample (n =496) excluded mothers who did not intend to have their daughters receive HPV vaccine in the next year. Overall, 67% of mothers who intended to vaccinate their daughters or had vaccinated their daughters reported being willing to have their daughters receive HPV vaccine at school. Mothers were more willing to allow their daughters to receive HPV vaccine in schools if they had not yet initiated the vaccine series for their daughters or resided in the Midwest or West (all p <.05). The two concerns about voluntary school-based provision of HPV vaccine that mothers most frequently cited were that their daughters’ doctors should keep track of her shots (64%) and that they wished to be present when their daughters were vaccinated (40%). Our study suggests that most mothers who support adolescent vaccination for HPV find school-based HPV vaccination an acceptable option. Ensuring communication of immunization records with doctors and allowing parents to be present during immunization may increase parental support. [Copyright &y& Elsevier]
