<p>As there was a gap in research focused on the autism spectrum disorder (ASD) genetic testing educational needs of Taiwanese parents of children with ASD, our objective was to explore their ASD genetic testing-related educational needs and preferences. Semi-structured interviews were conducted with 39 Taiwanese parents of children with ASD. All interview data were analyzed to identify emergent themes using content analysis. The study included 31 mothers and 8 fathers with a mean age of 42. Most interviewees were married (92.3%) and held a college degree or higher (61.5%). Most interviewees reported positive attitudes toward ASD genetic testing education and identified preferred educational topics that included: (1) ASD genetic testing cost, procedures, accuracy, reliability, benefits, risks, and scientific basis, (2) genetic testing report interpretation, and (3) the experiences of other parents whose children have undergone ASD genetic testing. Parents reported that their most preferred education methods were in-person lectures and seminars, printed health education materials, and web-based education and that they preferred receiving education from reliable sources including healthcare providers, ASD organizations, and schools. Taiwanese parents of children with ASD in this study expressed interest in ASD genetic testing education. They preferred a variety of topics and delivery methods and welcomed education from diverse sources. These findings provide significant implications for the development of evidence-based ASD genetic testing focused health education programs and materials tailored to the needs of parents of children with ASD in Taiwan.</p>
