There is increasing recognition of the co-occurrence of autism spectrum conditions (ASC) and psychosis, however, there is a lack of evidence regarding the clinical impact this may have. Psychosis and autism are both considered to exist on an extended phenotypic continuum, meaning co-occurrence and overlap at the trait level as well as at the diagnostic level may be important. 99 individuals experiencing a first episode of psychosis took part in the study. Traits of autism were found at elevated rates in the sample and 4 participants had a previous ASC diagnosis. 9.2% of participants had Autism Spectrum Quotient (AQ) scores of >32 (indicative that autism diagnosis is likely) and 28.7% scored >26 (indicative of high autism traits). Higher levels of autistic traits were associated with lower quality of life, lower functioning, and higher levels of current psychotic symptoms. Receiver operating characteristic (ROC) curve analyses indicated that even when autistic trait levels fall below what would be considered diagnostic for ASC, they may still have a significant impact on clinically relevant factors, including quality of life, functioning, and current psychotic symptoms. It is important that psychosis services have systems to adequately address the needs of individuals with higher autistic traits. In particular, it is important that clinical teams support autistic traits and treat psychotic symptoms.
