Objective: Screening asymptomatic men for prostate cancer is controversial and informed decision making is recommended. Within two prostate cancer screening programs, we evaluated the impact of a print-based decision aid (DA) on decision-making outcomes. Methods: Men (N = 543) were 54.9 (SD = 8.1) years old and 61% were African-American. The 2(booklet type: DA vs. usual care (UC)) x 2(delivery mode: Home vs. Clinic) randomized controllea trial assessed decisional and screening outcomes at baseline, 2-months, and 13-months. Results: Intention-to-treat linear regression analyses using generalized estimating equations revealed that DA participants reported improved knowledge relative to UC (B =.41, p <.05). For decisional conflict, per-protocol analyses revealed a group by time interaction (B = -.69,p <.05), indicating that DA participants were less likely to report decisional conflict at 2-months compared to UC participants (OR=.49, 95% CI:.26-.91, p <.05). Conclusion: This is the first randomized trial to evaluate a DA in the context of free mass screening, a challenging setting in which to make an informed decision. The DA was highly utilized by participants, improved knowledge and reduced decisional conflict. Practice implications: These results are valuable in understanding ways to improve the decisions of men who seek screening and can be easily implemented within many settings.
