Abstract

Genetic counseling can result in better outcomes when clients understand what to expect, and at least theoretically, at some point in their lifespan, anyone could be referred for or benefit from genetic counseling. Thus, in order to identify (and ultimately address) issues around awareness of genetic counseling and perceptions of its purpose, we surveyed the Canadian general population. We acquired 1,000 telephone numbers corresponding to a demographically representative sample of Canada from Survey Sampling International, and invited individuals to participate in a telephone-based survey. We administered a purpose-designed survey (in either French or English) comprising questions regarding: demographics, whether or not the individual had heard of genetic counseling, and 15 Likert scale-rated (strongly disagree-strongly agree) items about the possible purposes of genetic counseling. Responses to these 15 items were used to generate a total "knowledge score". Of the 1,000 numbers, n = 372 could not be reached, and the survey was successfully administered to n = 188 individuals (response rate 30 %). Most respondents (n = 129, 69 %) had not heard of genetic counseling, and substantial proportions thought that genetic counseling aims to prevent genetic diseases and abnormalities, help couples have children with desirable characteristics, and help people to understand their ancestry. These data could be used to inform the strategy for development of future awareness efforts, and as a baseline from which to measure their effects.
