An investigation of adherence to best practice guidelines for autism diagnosis in New Zealand.

Many clinicians in New Zealand do not follow guidelines for best practice in autism diagnosis. In this study, we investigated the processes that health professionals in New Zealand follow when diagnosing autistic children and adults. We asked 117 health professionals from a range of services and regions in New Zealand, how they identify and diagnose autism. We found that there are differences in the way that clinicians in New Zealand diagnose autism. We identified areas in which autism diagnosis in New Zealand could be improved, for example, by establishing more services to diagnose autism in adolescents and adults, and providing more consistent support after a person is diagnosed with autism. These findings will help to improve autism diagnosis in New Zealand.
