ABSTRACT
Background:
Ascertaining prior immunization with human papillomavirus (HPV) vaccine can be challenging and resource-intensive. Computer-assisted self-interviewing (CASI) instruments have the potential to address some of the challenges of self-report, and may also reduce the time, costs, and efforts associated with ascertaining immunization status.
Objective:
This study assesses both the feasibility and the accuracy of a CASI instrument to ascertain history of immunization with HPV vaccine.
Methods:
We developed a survey and a web-based data-collection system using CASI to ascertain self-reported HPV vaccine immunization history. We implemented the instrument in a sample of adult women enrolled in an ongoing study of HPV vaccine. Vaccine records of prior sources of care were reviewed to verify reported immunization history.
Results:
Among the 312 participants who provided HPV vaccine immunization history by self-report, almost all (99%) were able to do so using the CASI instrument. The accuracy of self-report was 84%; sensitivity was 89%; specificity was 80%; and the negative predictive value was 92%.
Conclusions:
We found that it is feasible to collect history of immunization with HPV vaccine using a CASI instrument. This approach is likely to be acceptable to adult women and is reasonably accurate in a clinical research setting.
