A systematic review of ecological momentary assessment in autism research.

Ecological momentary assessments assess people's in-the-moment thoughts and behaviours in their daily lives in natural environments. The number of ecological momentary assessment studies with autistic people has increased over the last decade. For the first time, this review (1) summarises how well ecological momentary assessment works for allowing autistic people to describe and express their thoughts, emotions and experiences, and (2) provides suggestions for the design of ecological momentary assessment to make this research method more accessible to future autistic participants. In total, we synthesised participation experiences from 930 autistic people. Overall, ecological momentary assessment is generally acceptable for autistic adults aged from 18 to 60 and with average or above-average intelligence and language. We also identified several issues in the ecological momentary assessment procedure and suggested researchers consider these when designing future ecological momentary assessment studies with autistic people. The findings of this review provide evidence that ecological momentary assessment can be used to investigate many different questions with autistic people and suggest a wider application of ecological momentary assessment in future studies with autistic people.
