Although the benefits of prostate cancer screening are uncertain and guidelines recommend that physicians share the screening decision with their patients, most U.S. men over age 50 are routinely screened, often without counseling. ⋯ Based on its internal consistency and its correlations with measures of physicians' net beliefs and self-reported practices, the knowledge scale developed in this study holds promise for measuring the effects of professional education on prostate cancer screening. The scale deserves further evaluation in broader populations.
