A community-based randomised controlled trial of three different educational resources for men about prostate cancer screening

Randomised evaluations of resources to facilitate informed decisions about prostate cancer screening are rarely conducted. In this study, 421 men recruited from the community were randomly allocated to receive a leaflet (n = 140) or one of two resources meeting criteria for a decision-aid: a video (n = 141) or an evidence-based booklet, developed by the authors (n = 140). Men in all three groups demonstrated significant increases in knowledge scores from pre to post-test. Scores were significantly higher at post-test amongst those who had received our evidence-based booklet compared with men who received the leaflet or video (P < 0.001). Scores were significantly modified by men's preferences for decisional control (P = 0.002). Decisional conflict was significantly lower amongst men receiving the evidence-based booklet (P = 0.038). Men receiving the evidence-based booklet also were less likely to accept a recommendation by a GP to undergo prostate-specific-antigen (PSA) screening (P = 0.003). Men require detailed information about the pros and cons of PSA screening in order to make an informed decision. Resources are not equivalent in achieving these outcomes.
