Fostering informed decisions: A randomized controlled trial assessing the impact of a decision aid among men registered to undergo mass screening for prostate cancer

Abstract

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)). ×. 2(delivery mode: Home vs. Clinic) randomized controlled 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
