To evaluate the impact of a theory-based health education intervention on awareness of prostate cancer and intention to screen among men in Western Jamaica. One hundred and eighty-eight men attending outpatient clinics in a hospital in Western Jamaica completed an interviewer-administered pretest survey. Following the pretest, participants received a health education intervention related to prostate cancer and an immediate post-test survey There were statistically significant increases in the percentage of correct responses between the pretest and post-test (p < 0.05). The greatest improvement was among items measuring knowledge of prostate cancer screening tests. Participants moved across the Stages of Change theoretical constructs indicating intention to screen. The sample was receptive to information about prostate cancer and the use of a theory-based educational intervention positively influenced knowledge of prostate cancer risk factors, symptoms, and types of screenings. Practice implications: This theory-based patient education programme can be replicated to promote awareness of prostate cancer and informed screening methods including potential risk associated with screening behaviours.
