Background Mental health problems are increasingly being recognised as a significant health need for people with autism spectrum disorder, but few specialist services are available. This study explored parents’ experiences of a specialist autism spectrum psychological intervention service located within a broader Neurodevelopmental and Social Communication Disorders Team. Method Forty‐nine parents completed a telephone based survey designed to assess experiences of a specialist intervention service. Results High levels of satisfaction were reported. Parents reported aspects of the service that they found most useful. Conclusion Most parents reported satisfaction with the service and suggested improvements were used to guide service development.
