Interview guide.

Several professional organizations recommend conducting genetic testing as part of the autism diagnosis process, as it can provide additional information and benefits for autistic people and their families. However, there is disagreement among autism communities about whether genetic testing reflects autistic people’s best interests. In practice, rates of clinical genetic testing for autism are much lower than diagnoses, creating a large gap between clinical guidelines and real clinical encounters. To investigate one potential source of this gap, we interviewed 14 healthcare providers about the autism diagnostic process and their actions related to autism genetic testing. We recruited a sample of primarily Ph.D. level-psychologists and analyzed our qualitative data using a five-step framework analysis method. Participants generally had positive or mixed views of genetic testing in autism. They described their current experiences of implementation of genetic testing, including that they did not often find it changed their clinical practice. Only some providers recommended it to everyone receiving an autism diagnosis. They also listed factors which discourage families from getting testing, including high costs, families feeling overwhelmed, other support needs taking priority, and ethical implications. Notably, providers highlighted a trend of referring patients to research genetic testing rather than clinical testing, which may provide a cheaper and easier alternative but is not likely to return results to participants. Finally, participants felt they needed more training in genetics and listed specific topics of uncertainty. Our research highlights a need to further educate clinicians in the uses and limitations of genetic testing for autism and suggests content areas of focus for genetics educators.</div
