The study investigated whether EMDR is a feasible therapy for adults with ASD and a history of adverse events, and whether it is associated with reductions in symptoms of PTSD, psychological distress and autism. Participants received 6 to 8 weeks treatment as usual (TAU), followed by a maximum of 8 sessions EMDR added to TAU, and a follow-up of 6–8 weeks with TAU only. Results showed a significant reduction of symptoms of post-traumatic stress (IES-R: d = 1.16), psychological distress (BSI: d = 0.93) and autistic features (SRS-A: d = 0.39). Positive results were maintained at follow-up. The results suggest EMDR therapy to be a feasible and potentially effective treatment for individuals with ASD who suffer from the consequences of exposure to distressing events.
