Feasibility of psychosis risk assessment for adolescents diagnosed with autism

Individuals with autism may experience a variety of psychiatric symptoms that may cause distress and difficulty functioning. The tools that exist to help evaluate symptoms for psychosis for individuals with autism are limited. We investigated whether a specialized interview for symptoms of psychosis risk could be used for adolescents with autism. We recruited 21 adolescents with autism and 22 typically developing adolescents and interviewed them using the Structured Interview for Psychosis-Risk Syndromes. Participants were asked to rephrase interview questions as a way to understand how they interpreted the question. Their responses were evaluated by clinicians and third-party raters to determine potential response errors. Results of the study showed that youth with autism who have intact language skills are able to answer questions about psychosis risk symptoms as well as their typically developing peers. In general, adolescents across both groups who had more difficulty with nonliteral language (understanding words with multiple meanings) had more difficulty completing the Structured Interview for Psychosis-Risk Syndromes. Problematic items that required more clarification by the clinician involved misinterpretation of words/phrases or questions. Care should be taken to ensure adolescents understand the intent of interviewer questions when assessing risk of psychosis.
