Brief Summary

This clinical trial studies how well an educational intervention works in increasing knowledge about prostate cancer in high-risk neighborhoods. Learning about prostate cancer and the pros and cons of screening for prostate cancer may increase knowledge about prostate cancer while decreasing anxiety and concerns about prostate cancer screening.

Outcome Measures

Primary Outcomes (2)

• Change in Prostate Cancer Knowledge as Measured by the Decisional Conflict Scale

  The Decisional Conflict Scale (DCS) measures uncertainty in health decision-making. It includes 16 items rated on a 5-point Likert scale. Scores are calculated by averaging item responses and multiplying by 25, yielding a range from 0 (no conflict) to 100 (high conflict). Lower scores indicate greater clarity, confidence, and satisfaction with the decision. Higher scores reflect uncertainty, lack of information/support, and low confidence. The self-efficacy subscale assesses confidence in decision-making with responses like "a lot confident," "a little confident," or "not at all confident."

  4 months

• Intent to Screen for PCa

  Estimated mean changes from baseline assessment in likelihood of screening by study group from baseline to 4 month follow up. Intent to screen for prostate cancer was measured on a 5 point Likert Scale (1= very unlikely to 5=very likely). Results represent estimated mean change and 95% Confidence Interval from baseline in intent-to-screen score.
