Our findings suggest that the race and sex of a patient independently influence how physicians manage chest pain.

Addressing health disparities has been a national challenge for decades. The National Institutes of Health-sponsored Centers for Population Health and Health Disparities are the first federal initiative to support transdisciplinary multilevel research on the determinants of health disparities. Their novel research approach combines population, clinical, and basic science to elucidate the complex determinants of health disparities. The centers are partnering with community-based, public, and quasi-public organizations to disseminate scientific findings and guide clinical practice in communities. In turn, communities and public health agents are shaping the research. The relationships forged through these complex collaborations increase the likelihood that the centers' scientific findings will be relevant to communities and contribute to reductions in health disparities.

Standard educational approaches may be equally effective as expanded counseling approaches in enhancing knowledge. Since knowledge is a key aspect of medical decision-making, standard education may be adequate in situations where genetic testing must be streamlined. On the other hand, it has been argued that optimal decision-making requires not only knowledge, but also a reasoned evaluation of the positive and negative consequences of alternate decisions. Although the counseling approach is more likely to achieve this goal, it may not diminish interest in testing, even among women at low to moderate risk. Future research should focus on the merits of these alternate approaches for subgroups of individuals with different backgrounds who are being counseled in the variety of settings where BRCA1 testing is likely to be offered.

One of the greatest challenges facing health promotion and disease prevention is translating research findings into evidence-based public health and clinical practices that are actively disseminated and widely adopted. Despite the tremendous strides made in developing effective disease prevention and control programs, there has been little study of effective dissemination of evidence-based programs to and adoption by community, public health, and clinical practice settings. This special section provides a venue in which to highlight exemplary dissemination research efforts while also identifying limitations in research to date and framing important future research questions. This issue establishes a resource for investigators interested in dissemination research, with relevance to health psychology. In this sense, it can serve as a benchmark by which to examine subsequent progress. The 6 articles reflect the state of the science in dissemination research for the promotion and adoption of health behavior change interventions.
