A Qualitative Analysis of Knowledge Levels, Perceived Susceptibility, and Perceived Severity Surrounding Anal Cancer and Human Papillomavirus.

Abstract

When examining health literacy and disease specific knowledge levels across ethnicities and communities, ethnic minority groups are known to be at a higher risk of being below the average health literacy threshold which is a factor linked to poor health status and higher mortality rates. This study examined disease specific knowledge levels, perceived severity, and perceived susceptibility surrounding anal cancer and HPV-related screening behaviors. The following research questions were explored: (1) "What are the common themes and/or beliefs when asked about anal cancer, HPV, and preventive screening?" and (2) "What are the common themes and beliefs surrounding the severity and susceptibility of contracting anal cancer?". This study utilized a cross-sectional design to survey 26 individuals regarding their knowledge level and perspectives regarding anal cancer and HPV. An 8-question survey was developed de novo based on an application of the Health Belief Model (HBM) elements. This study employed thematic analysis to explore critical themes to construct a model to understand knowledge levels, attitudes, and risk perceptions regarding anal cancer and intention to participate in preventive screenings. The fundamental attitudes and themes related to anal cancer risk and intention to participate in preventative screenings were elicited using a qualitative descriptive technique. Coded data was utilized to analyze themes based on (1) knowledge and (2) perceived risk, both severity and susceptibility. Overall, the findings indicate very low levels of knowledge regarding screening, anal cancer, and HPV across all genders. The low levels of anal cancer and HPV knowledge were seen in 13 coded segments (50% of surveys) which showed no familiarity with or comprehension of HPV, and 4 coded segments indicated no familiarity with anal cancer. In addition, 15 respondents (57%) had low or no preventive or screening-related knowledge. While some respondents (46%) illustrated high perceived severity for anal cancer, only 23% indicated high perceived susceptibility for anal cancer. The results from this study may be used to inform practitioners, providers, and policymakers in developing interventions addressing low levels of understanding and disease specific knowledge surrounding anal cancer in support of creating a standardized health screening procedure.
