The purpose of this study was to qualitatively assess attitudes associ
ated with the willingness of African-Americans to participate in prost
ate cancer clinical trials, Fifty-six African-American males, 40 years
of age and older, were recruited from South Central Los Angeles. Resp
ondents were divided into lower or middle socio-economic groups based
on education and occupation. Focus group discussions were conducted to
assess their knowledge about prostate cancer and willingness to parti
cipate in prostate cancer clinical trials. In addition, information wa
s obtained to identify their incentives and barriers toward participat
ing in prostate cancer research. Middle socio-economic respondents exp
ressed a greater willingness to participate in prostate cancer clinica
l trials than did men of lower socio-economic status. Many indicated t
hat they would be more likely to participate if they were encouraged t
o do so by a physician or researcher who was viewed as being competent
and compassionate. Barriers to participation in prostate cancer clini
cal trials included concerns about drug toxicity, medical experimentat
ion and distrust of the medical establishment. Endeavors aimed at incr
easing minority representation in prostate cancer clinical studies sho
uld address these issues.
