Community Interventions in Non-Medical
Settings to Increase Informed Decision
Making for Prostate Cancer Screening

Prostate cancer is the most common non-cutaneous malignancy
diagnosed and is the second leading cause of cancer death among
men in the U.S. In the absence of evidence of the efficacy of
prostate cancer screening, medical organizations advise men to
discuss potential risks and benefits of screening with their
physicians and to make individualized screening decisions. The
overall goal of this study is to develop, implement and evaluate
a worksite model for prostate cancer education designed to
promote informed decision-making regarding screening.
Worksites provide access to a large segment of the at-risk
population, a location in which educational efforts can be
offered repeatedly, and a setting where programs can be
institutionalized and sustained over time. This study employs a
randomized controlled design, where 16 worksites will be
assigned to either a non-intervention control condition, or to
an intervention condition that includes an interactive,
computerized decision aid that will facilitate individualized
screening decisions. The primary outcome is informed decision
making. Secondary outcomes include satisfaction with the
decision-making process and with the decision, as well as
decisional conflict. Outcomes will be measured in a pre/post
self-administered survey conducted among male employees
age 50-65 in participating worksites. A comprehensive process
evaluation system will assess worksite participation rates,
intervention dose delivered, program reach and cost. If proven
effective, this intervention model may easily be adapted for
broad dissemination to other worksites, alternative community
settings, and diverse audiences.
