Understanding parents' educational needs concerning genetic testing for their children with autism spectrum disorder (ASD) is important in developing tailored, evidence‐based health education materials for clinical use. Since research is lacking in this area, to bridge the gap, we examined genetic testing education needs using a nationwide sample of parents of biological children with ASD in the United States. Prospective participants were recruited from the interactive autism network, and 552 parents of biological children with ASD completed the online survey. Most participants (73.7%) were interested in receiving health education about genetic testing. Yet, the majority of them (64.7%) reported that they did not receive the information needed from physicians. Parents who identified as racial/ethnic minorities (P = 0.029), who had an education degree below college (P = 0.002), or displayed low/no awareness of genetic testing (P = 0.003) were more interested in receiving health education regarding genetic testing. Parents' most desired topics for health education include the accuracy of genetic testing (88.4%), cost (85.9%), relevant benefits of such testing (83.8%), testing procedure (77.8%), eligibility to undergo genetic testing for their children with ASD (62.4%), potential harms caused by genetic testing (56.1%), previous use and experience among individuals affected by ASD (50.8%), and confidentiality issues (48.0%). Furthermore, web‐based education was the preferable approach (85.4%). Our findings can help develop health education programs and/or materials regarding genetic testing for parents and physicians to facilitate better physician‐parent communication and assist parents in making informed medical decisions regarding genetic testing.
