Relation of family history of prostate cancer to perceived vulnerability and screening behavior

Men with a positive family history of prostate cancer are known to be at increased risk for the disease; however, relatively little is known about their risk perceptions or screening behavior. To address these issues, the current study examined the relationship of family history of prostate cancer to perceived vulnerability of developing prostate cancer and prostate cancer screening practices. Participants were 83 men with a positive family history of prostate cancer and 83 men with a negative family history of prostate cancer. As predicted, men with a positive family history reported greater (p< or =0.05) perceived vulnerability of developing prostate cancer and stronger intentions to undergo screening (p< or =0.05). They also reported greater past performance of prostate-specific antigen screening and were more likely to request information about prostate cancer (p< or =0.05). Additional analyses indicated that perceived vulnerability mediated the relation between family history and intentions to undergo prostate cancer screening. Findings confirm the increased likelihood of men with a positive family history to undergo prostate cancer screening and suggest that heightened concerns about developing the disease are an important motivating factor.
