: No standardized instruments, to our knowledge, exist to assess attitudes and beliefs about human papillomavirus (HPV) vaccination.
: We developed the Carolina HPV Immunization Attitudes and Beliefs Scale (CHIAS), using data collected on 783 parents who had not yet vaccinated their daughters against HPV. We conducted a principal components analysis of 16 HPV vaccine attitude and belief items, assessed the scale's psychometric properties, and used linear regression to examine the relationship of CHIAS factors and parents' vaccination intentions.
: Analyses identified 4 CHIAS factors, all of which had acceptable scale alphas and 1-year test-retest reliability. In multivariate models, higher vaccination intentions were associated with: believing HPV vaccine is effective (β = 0.06) or has less harmful effects (β = -0.47), perceiving more barriers to access (β = 0.18), and having less uncertainty about the vaccine (β = -0.23) (all P < 0.05).
: Findings suggest that parent attitudes about HPV vaccine are important to their intentions to vaccinate their adolescent daughters against HPV. The CHIAS offers researchers a compact, standardized measure of important HPV vaccine attitudes and beliefs.

    • "Using items based on the Carolina HPV Immunization Attitudes and Beliefs Scale (CHIAS) [32], the parent survey measured perceived potential harms of HPV vaccine (5 items, ˛ = 0.57, possible range = 1–5), perceived barriers to getting sons HPV vaccine (2 items, ˛ = 0.62, possible range = 1–3), and uncertainty about HPV vaccine (3 items, ˛ = 0.55, possible range = 1–5). We assessed parents' anticipated regret if their sons received HPV vaccine and fainted (possible range = 1–4) and if their sons did not get vaccinated and later developed an HPV infection (possible range = 1–4).

    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.

    • "Questions were related to knowledge of HPV and the vaccine, health care and provider characteristics, attitudes about HPV vaccine, vaccine uptake by daughters, and intention to vaccinate daughters. Most questions were taken or adapted from measures used in previous studies [13] [14] [15]. "

    ABSTRACT: We assessed human papillomavirus (HPV) vaccine uptake among adolescent girls, parents' intentions to vaccinate daughters, and barriers and facilitators of vaccination in a population at elevated risk for cervical cancer. Between October 2007 and June 2008, telephone surveys were conducted with randomly selected parents/guardians of 11-18 year old girls attending public middle and high schools serving economically disadvantaged populations in Los Angeles County. We surveyed 509 predominantly Hispanic (81%) and African American (16%) parents; 71% responded in Spanish. Overall, 23% reported their daughter had received ≥ 1 dose of HPV vaccine. Although 93% of daughters had seen a doctor in the past year, only 30% reported that a provider recommended HPV vaccine. Characteristics positively associated with odds of having initiated HPV vaccine were having heard of the vaccine (adjusted odds ratio [aOR] 2.6), belief in vaccine effectiveness (aOR 2.9), and doctor recommendation (aOR 48.5). Negative attitudes toward HPV vaccine (aOR 0.2) and needing more information about it (aOR 0.1) were negatively associated with vaccine initiation. Of those with unvaccinated daughters (n=387), 62% said they "probably/definitely will" vaccinate within the next year and 21% were undecided or didn't know; only 11% said they definitely won't. About one-quarter of adolescent girls in this at-risk community had initiated HPV vaccine by mid-2008. Provider recommendation was the single most important factor associated with vaccination. Because a substantial proportion of parents remain undecided about HPV vaccine, health care providers can play a key role by providing needed information and offering HPV vaccine to all eligible adolescents.

    ABSTRACT: The paper presents the first results from the European project VACSATC which aimed to track parental attitudes on vaccinations across several European countries. We compared five cross-sectional surveys of parents with children less than 3 years of age in England, Norway, Poland, Spain and Sweden carried out during 2008-2009. Data were collected from 6611 respondents. Two countries used face-to face interviews, one used telephone interviews, and two other countries used mail-in questionnaires. In all countries health professionals were indicated as the most important and trusted source of information on vaccination. The study results also show that parental attitudes on vaccinations in the childhood vaccination programs are generally positive. However, there were differences in attitudes on vaccination between the five countries, possibly reflecting different methods of sampling the respondents, context-specific differences (e.g. level of activity of governmental agencies), but also individual-level parental variation in demographic and socioeconomic status variables.
