It was expected that personalized risk information generated by genetic discovery would motivate risk-reducing behaviors. However, though research in this field is relatively limited, most studies have found no evidence of strong negative nor positive psychological or behavioral influences of providing genetic information to improve individual health behaviors. As noted by systematic reviews and agenda-setting commentaries, these null findings may be due to numerous weaknesses in the research approaches taken to date. These include issues related to study samples and design, as well as the motivational potency of risk communications. Moreover, agenda-setting commentaries have suggested areas for improvement, calling for expanded consideration of health outcomes beyond health behaviors to include information exchange and information-seeking outcomes and to consider these influences at the interpersonal and population levels.
A new generation of research is adopting these recommendations. For example, there is a growing number of studies that are using communication theory to inform the selection of potential moderating factors and their effects on outcomes in understanding interpersonal effects of shared genetic risk. Researchers are taking advantage of natural social experiments to assess the general public’s understanding of genetics and inform approaches to improve their facility with the information. Additionally, there are examples of risk communication approaches addressing the complexity of genetic and environmental contributors to health outcomes. Although the pace of this translation research continues to lag behind genetic discovery research, there are numerous opportunities for future communications research to consider how emerging genomic discovery might be applied in the context of health promotion and disease prevention.
