Objective. To examine the effects of a community-based intervention on decisions about prostate-specific antigen (PSA) screening using multiple measures of informed decision making (IDM).
Data Sources/Study Setting. Nonequivalent control group time series design collecting primary data in late 2004 and 2005.
Study Design. We developed a multimodal intervention designed to convey the medical uncertainty about the benefits of PSA screening and early treatment and the limited predictive ability of both the PSA test and pathological specimens collected from prostate biopsy. We examined (1) patients' recognition that there is a decision to be made about PSA screening, (2) prostate cancer knowledge levels, (3) their preferred and actual levels of participation in decision making about screening at three points in time, and (4) screening decision.
Data Collection. Baseline data collection occurred in community-based organizations. These organizations served as recruiting sources and as sites for the intervention. We collected follow-up data by mail with telephone reminders.
Principal Findings. Our intervention was associated with greater recognition of the PSA test as a decision to be made, levels of knowledge, both preferred and actual levels of involvement in decision making, but did not have an impact on the screening decision.
Conclusions. Community-based interventions can influence key measures of IDM about PSA screening.
