<qa>  What is the purpose of the study?In this study, we propose to: 1 develop an interactive computer-based decision aid DA to promote IDM for CaP screening; and 2 conduct a randomized controlled worksite trial to evaluate the impact the DA intervention on employed mens ability to make informed decisions regarding CaP. This work is designed to be responsive to recent calls for IDM interventions in community settings among diverse populations. If successful, our findings could validate the effectiveness of DAs to promote IDM for CaP and serve as a model for widespread dissemination, thus improving quality of care.
