The Student Human Papillomavirus Survey: Nurse-Led Instrument Development and Psychometric Testing to Increase Human Papillomavirus Vaccine Series Completion in Young Adults

Abstract

Background and purpose: The Student Human Papillomavirus Survey (SHPVS) was developed to examine students' perceived benefits or barriers to human papillomavirus (HPV) vaccination.

Methods: Survey development included (a) 2-phase integrative literature reviews; (b) draft of survey items based on the literature; (c) critique of survey items by young adults, nursing and psychology faculty, and health care providers; and (d) pilot testing. The psychometric properties of the SHPVS were evaluated using classical item analysis and exploratory factor analysis (EFA) among a sample of 527 university students' ages 18-24 years.

Results: The estimated Cronbach's alpha for the SHPVS is .74.

Conclusions: The SHPVS is a measure of young adults HPV perceived vulnerability, perceived severity, perceived barriers, and perceived benefits of HPV vaccination.
