Schizophrenia spectrum disorders (SSDs) and autism spectrum disorder (ASD) both feature social cognitive deficits,
1,2 which contribute to disability and poor functional outcome,
3,4 and have limited treatment options. Overlapping clinical symptoms in SSDs and ASD, and social impairments in particular, have long been recognized. Highly heterogeneous clinical presentation is also characteristic within and across these disorders.
5-7 Although historically few studies have included both diagnostic groups, cross-disorder research on social cognition in people with SSDs and ASD is increasing because of a shift toward transdiagnostic research,
8 use of the Research Domain Criteria framework,
9 and the prioritization of improving functional outcome.
