The main objective of this pilot study is to provide insight into the process of prenatal genetic counseling that can both inform the practice of prenatal genetic counseling and serve as the springboard to a later, more comprehensive study. The research participants will all be practicing prenatal genetic counselors recruited from regional meetings and a national meeting of the National Society of Genetic Counselors. Participating genetic counselors will be asked to perform a prenatal genetic counseling session with a simulated client (an actor) or simulated clients (actor and actor posing as spouse) presenting with the indication of advanced maternal age. The participating genetic counselors will also be asked to address cystic fibrosis carrier testing within the course of this session. This session will be videotaped. In addition, both the genetic counselor and simulated client will be asked to fill out questionnaires related to characteristics of the counselor and the session itself. The process and content of the genetic counseling communication will be analyzed qualitatively and quantitatively (using Roter Interaction Analysis System). Through these analyses, we hope to both describe the nature of prenatal genetic counseling communication in a relatively large sample and to determine the ways in which a variety of client and counselor factors affect the communication process itself (determined through changes in the RIAS communication codes). In addition, we hope to provide information on the logistics of data collection in order to inform a similar larger study planned to look at the impact of communication on client outcomes.
