Study Population	Sample Size	Percent Expressing Interest in Genetic Testing	Other Findings
Prostate screening clinic participants [17]	342 men aged 40 to 97 years	89%	28% did not demonstrate an understanding of the concept of inherited predisposition to cancer
General population; 9% with positive family history [8]	12 focus groups with a total of 90 men aged 18 to 70 years	All focus groups
African American men [18]	320 men aged 21 to 98 years	87%	Most participants could not distinguish between genetic susceptibility testing and a prostate-specific antigen blood test
Men with and without first-degree male relatives with prostate cancer [9]	126 men older than 40 years; mean age 52.6 years	24% definitely; 50% probably
Swedish men with a FDR with prostate cancer [3]	110 men aged 40 to 72 years	76% definitely; 18% probably	89% definitely or probably wanted their sons to undergo genetic testing
Sons of Swedish men with prostate cancer [10]	101 men aged 21 to 65 years	90%; 100% of sons with 2 to 3 family members affected with prostate cancer	60% expressed worry about having an increased risk for prostate cancer
Healthy outpatient males with no history of prostate cancer [19]	400 men aged 40 to 69 years	82%
Healthy African American males with no history of prostate cancer [20]	413 African American men aged 40 to 70 years	87%	Belief in the efficacy of and intention to undergo prostate cancer screening was associated with testing interest
