Summary
A video intervention effectively improved prostate cancer screening knowledge for African American men, regardless of their health literacy levels. The study found the educational video to be highly credible and understandable.
Area of Science:
- Public Health
- Health Communication
- Health Disparities
Background:
- Prostate cancer screening decisions require informed consent, particularly among African American men who face higher incidence and mortality rates.
- Health literacy significantly impacts understanding and engagement with health information, potentially creating disparities in informed decision-making for cancer screening.
Purpose of the Study:
- To assess the applicability of an evidence-based video intervention designed to enhance informed decision-making for prostate cancer screening.
- To evaluate the intervention's effectiveness across African American men with varying levels of health literacy.
Main Methods:
- A pretest-posttest study design involving 49 African American men.
- Health literacy assessed using the Test of Functional Health Literacy in Adults.
- Repeated measures ANCOVA and binomial distributions used to analyze knowledge changes; descriptive statistics for participant perceptions.
Main Results:
- Men with functional health literacy initially had higher prostate cancer screening knowledge than those with inadequate literacy.
- The video intervention reduced pre-existing knowledge gaps between groups, indicating improved understanding across literacy levels.
- Over 94% of participants found the video credible, trustworthy, understandable, and complete.
Conclusions:
- The video intervention is suitable for promoting informed decision-making regarding prostate cancer screening in African American men with diverse health literacy.
- Further research is recommended to examine the intervention's influence on screening intentions and actual screening behaviors.
