Abstract
Background: Human papillomavirus (HPV) is the most common sexually transmitted infection in the U.S. Cervical cancer (CC) is the most common HPV-associated cancer, and Korean Americans (KAs) experience one of the highest CC incidence and mortality rates among Asian Americans. Awareness and knowledge of HPV and HPV vaccine are essential in preventing HPV-associated cancers; however, studies emphasize low HPV awareness and knowledge among KAs. Although HPV causes cancers in both men and women, there exist misconceptions that the HPV vaccine is only for women and not for men. Furthermore, research on HPV vaccination among KAs has been conducted mostly among women. The health belief model (HBM) is a value-expectancy theory that is used to explain and predict individual changes in health behaviors and has been used in multiple studies that aimed to understand HPV vaccination behavior. Purpose: The purpose of this study is to develop an HBM guided text messaging program to increase HPV awareness, knowledge, and HPV vaccination among Korean young adults in the U.S. Methods: A total of 10 Korean young adults between the ages of 18 and 26 completed the mixed methods study. The survey examined HPV, HPV vaccine, and cervical cancer awareness and knowledge, beliefs, and vaccination intention. The qualitative interview with cognitive response testing (CRT) of the text messages, which were preconstructed based on previous literature and six constructs of HBM, allowed participants to provide feedback on the comprehension and emotional response to the messages, and any other recommendations to improve the content and delivery of the messages. Results: All participants (N=10) indicated to have never received the HPV vaccine and most participants had no intention to receive the HPV vaccine within one year. Although most of the participants were aware of HPV and HPV vaccine, overall knowledge of HPV, HPV vaccine, and cervical cancer were low. The interviews revealed that reasons for vaccine hesitancy and non-vaccination included cost, inconvenience, and low perceived susceptibility. Especially, there was low perception of the importance of HPV vaccination for males. Overall, findings from the CRT showed that there was a clear understanding of the preconstructed text messages. There was a consensus on the duration and timing of the messages and participants provided recommendations on the content, tone, and structure of the messages. Using the HBM, participants’ feedback on HPV awareness, knowledge, and vaccination intention, the text messaging library was revised and includes a total of 9 text messages over the four days. Conclusions: This study provides important insights into the development of an educational text messaging program among Korean young adults in the U.S. Current study will build a foundation for an educational mobile health program to help increase awareness and knowledge of HPV and HPV-associated cancers, as well as HPV vaccination intention, and impact HPV-associated cancer rates among KAs through vaccination in the long term.
