Item Population-Level Effects of Human Papillomavirus Vaccination Programs on Infections with Nonvaccine Genotypes.(CDC, 2016-10) Mesher, David; Soldan, Kate; Lehtinen, Matti; Beddows, Simon; Brisson, Marc; Brotherton, Julia M. L.; Chow, Eric P. F.; Cummings, Teresa; Drolet, Mélanie; Fairley, Christopher K.; Garland, Suzanne M.; Kahn, Jessica A.; Kavanagh, Kimberley; Markowitz, Lauri; Pollock, Kevin G.; Söderlund-Strand, Anna; Sonnenberg, Pam; Tabrizi, Sepehr N.; Tanton, Clare; Unger, Elizabeth; Thomas, Sara L.; Department of Pediatrics, IU School of MedicineAfter introduction of vaccination, some prevalences of nonvaccine types changed, without clear evidence for type replacement.Item School-based HPV vaccination positively impacts parents’ attitudes toward adolescent vaccination(Elsevier, 2021-07) Davies, Cristyn; Stoney, Tanya; Hutton, Heidi; Parrella, Adriana; Kang, Melissa; Macartney, Kristine; Leask, Julie; McCaffery, Kirsten; Zimet, Gregory; Brotherton, Julia M. L.; Marshall, Helen S.; Skinner, S. Rachel; HPV.edu Study Group; Pediatrics, School of MedicineIntroduction This qualitative study aimed to explore parental attitudes, knowledge and decision-making about HPV vaccination for adolescents in the context of a gender-neutral school-based Australian National Immunisation Program (NIP). Methods Semi-structured interviews with parents of adolescents eligible for HPV vaccination were undertaken as part of an evaluation of a cluster-randomised controlled trial of a complex intervention in 40 schools (2013–2015). In this qualitative study, we purposively recruited a nested sample of parents from 11 schools across two Australian jurisdictions. Interviews explored parent knowledge and understanding of the HPV vaccine program; HPV vaccination decision-making; their adolescent’s knowledge about HPV vaccination; and their adolescent’s understanding about HPV vaccination, sexual awareness and behaviour. Transcripts were analysed using inductive and deductive thematic analysis. Results Parents’ of 22 adolescents had positive attitudes towards the program; the school-based delivery platform was the key driver shaping acceptance of and decision-making about HPV vaccination. They had difficulty recalling, or did not read, HPV vaccination information sent home. Some adolescents were involved in discussions about vaccination, with parents’ responsible for ultimate vaccine decision-making. All parents supported in-school education for adolescents about HPV and HPV vaccination. Parents’ knowledge about HPV vaccination was limited to cervical cancer and was largely absent regarding vaccination in males. Conclusions Parents’ positive attitudes towards the NIP and inclusion of the HPV vaccine is central to their vaccine decision-making and acceptance. More intensive communication strategies including school education opportunities are required to improve parents’ knowledge of HPV-related disease and to promote vaccine decision-making with adolescents.Item Understanding the Challenges of HPV-Based Cervical Screening: Development and Validation of HPV Testing and Self-Sampling Attitudes and Beliefs Scales(MDPI, 2023-01-15) Tatar, Ovidiu; Haward, Ben; Zhu, Patricia; Griffin-Mathieu, Gabrielle; Perez, Samara; McBride, Emily; Lofters, Aisha K.; Smith, Laurie W.; Mayrand, Marie-Hélène; Daley, Ellen M.; Brotherton, Julia M. L.; Zimet, Gregory D.; Rosberger, Zeev; Pediatrics, School of MedicineThe disrupted introduction of the HPV-based cervical screening program in several jurisdictions has demonstrated that the attitudes and beliefs of screening-eligible persons are critically implicated in the success of program implementation (including the use of self-sampling). As no up-to-date and validated measures exist measuring attitudes and beliefs towards HPV testing and self-sampling, this study aimed to develop and validate two scales measuring these factors. In October-November 2021, cervical screening-eligible Canadians participated in a web-based survey. In total, 44 items related to HPV testing and 13 items related to HPV self-sampling attitudes and beliefs were included in the survey. For both scales, the optimal number of factors was identified using Exploratory Factor Analysis (EFA) and parallel analysis. Item Response Theory (IRT) was applied within each factor to select items. Confirmatory Factor Analysis (CFA) was used to assess model fit. After data cleaning, 1027 responses were analyzed. The HPV Testing Attitudes and Beliefs Scale (HTABS) had four factors, and twenty-two items were retained after item reduction. The HPV Self-sampling Attitudes and Beliefs Scale (HSABS) had two factors and seven items were retained. CFA showed a good model fit for both final scales. The developed scales will be a valuable resource to examine attitudes and beliefs in anticipation of, and to evaluate, HPV test-based cervical screening.
