Indiana University-Purdue University Indianapolis (IUPUI) / Women who are medically underserved may be less likely to obtain provider-based
cervical cancer screening because of structural and intrapersonal barriers. Self-collection
for human papillomavirus (HPV) testing, a method for women to collect their
own sample through a vaginal swab or urine collection, has accuracy comparable to
provider-based cervico-vaginal HPV testing and may be useful in overcoming barriers to
provider-based cervical cancer screening. The purpose of this dissertation study is to
examine factors associated with self-collection for HPV testing, psychometrically test
Diffusion of Innovations (DOI) instruments, and identify preferences for self-collection
for HPV testing. Three distinct aims were developed: 1) factors (sociodemographic,
health-related, and theoretical variables) associated with mailed return of vaginal self-collection
for HPV testing, 2) psychometric examination of DOI ÷instruments (relative
advantages and complexity), and 3) dimensions of self-collection and characteristic
preferences to self-collection for HPV testing stratified by age cohorts.
This dissertation involved two cross-sectional studies. In Chapters 2-3, data were
collected from women (n=168) at food pantries and online. Women were eligible if they
were: 1) female, 2) between the ages of 30-65, 3) could read and speak English, and 4) at
2019 federal poverty guidelines for income and family size as defined by the Department
of Health and Human Services. Women were not eligible if they had a history of
hysterectomy or were adherent to cervical cancer screening guidelines. Logistic
regression analyses, item analysis, Cronbach’s alpha, exploratory factor analysis, and
tests were used to analyze data. Chapter 4 involved collection of data from an online
survey with a sample (n=878) provided by Dynata. Participants evaluated 9 scenarios that
varied along 4 attributes: HPV self-collection kit type (vaginal swab or urine collection),
HPV self-collection kit delivery (mail, pharmacy pick-up, or clinic pick-up), HPV self-collection
kit return (mail, pharmacy drop-off, or clinic drop-off), and HPV test result
communication (mail, phone call, or text message). Ratings-based conjoint analysis
(RBCA) determined how each attribute influenced the ratings of each scenario.
