Research suggests that when healthcare providers lack cultural competence, minority groups, including the Deaf community, are adversely affected. Although most genetic counseling programs incorporate cultural competency training into their curricula, the extent and impact of Deaf awareness training is unknown. The purpose of this study is to assess Deaf awareness training of recent graduates and its impact on knowledge of deafness and Deaf culture, and attitudes toward deaf people. Genetic counselors who graduated within the past 5 years were invited to participate in an anonymous, online survey. Of the 135 respondents, 26 % reported no Deaf awareness training and 51 % reported limited training (1-2 h) conducted primarily by program instructors. Nearly one-third felt their Deaf awareness training was insufficient. Respondents lacked knowledge regarding effects of cochlear implants on residual hearing, communication between deaf children and hearing parents, and working with sign language interpreters. However, scores on knowledge of deafness and Deaf culture items and scores on attitudes toward deaf people scale did not differ significantly between respondents who had Deaf awareness training and those who did not. These findings suggest that genetic counseling students may not receive adequate Deaf awareness training. Future efforts should focus on increasing Deaf awareness in genetic counseling students, and investigating whether this change improves genetic counseling experiences for Deaf individuals.
