title: Translating medical evidence to promote informed health care decisions.
abstract: 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).
  
  
  METHODS
  Nonequivalent control group time series design collecting primary data in late 2004 and 2005.
  
  
  METHODS
  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.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
