Background: The assessment of schizophrenia in autistic people with intellectual disabilities is challenging. This study aimed to explore the identification of schizophrenia in this population. Methods: Using data from a clinical multi‐centre study, reported symptoms in 26 autistic individuals with intellectual disabilities diagnosed with co‐occurring schizophrenia were explored. Scores on two checklists (Psychopathology in Autism Checklist [PAC], Aberrant Behaviour Checklist [ABC]) were compared with two comparison groups: autistic individuals with intellectual disabilities and other mental disorders (94), or no mental disorder (63). Results: Reported symptoms of schizophrenia in this population met the formal diagnostic criteria. For PAC/ABC scales, only PAC psychosis differed for the schizophrenia group. Among participants with schizophrenia, two were diagnosed with additional mental disorders. Elevated scores for anxiety and depression were common. Conclusions: Emphasising core symptoms seems necessary when assessing co‐occurring schizophrenia in autistic people with intellectual disabilities. The PAC may serve as a helpful screening tool.

Background: The identification and treatment of psychiatric disorders in individuals with autism spectrum disorders (ASD) and ID presents many challenges. We describe the development of a professional network, together with a standardized protocol for clinical assessment, designed to promote clinical competence and professional development in eight clinical centers responsible for providing mental health services to autistic individuals with ID across all four health regions of Norway. Specific aims to describe: (1) patterns of psychiatric and behavior problems in patients treated by the network, (2) patterns of change over time, and (3) the relationship between psychiatric disorders and behavior problems. Method: A standardized protocol was used to assess individual progress in 132 patients (inpatients and outpatients) with autism and ID over 2 years (at referral (T1), after 1 year (T2), and after 2 years (T3)). Changes in psychiatric symptoms and behavior problems were assessed with the Psychopathology in Autism Checklist (PAC) and Aberrant Behavior Checklist (ABC). Results: Patients showed significant (p <.001) improvements from T1 to T2 on the psychosis, depression and anxiety subscales of the PAC, but no significant improvement on the obsessive compulsive disorder (OCD) subscale. Improvements were maintained from T2 to T3. Patients showed significant (p <.01) improvements on the ABC total score and on all ABC subscales except inappropriate speech from T1 to T2; these improvements were maintained from T2 to T3. Discussion The combination of a professional network and a standardized protocol for clinical assessment has promise as a strategy for improving professional competence and facilitating specialized mental health services for autistic individuals with ID and psychiatric disorders across an extensive geographical area.

Background: Individuals with autism spectrum disorder (ASD) and intellectual disability (ID) are at increased risk of potentially traumatic events and may be at increased risk of post‐traumatic stress disorder (PTSD). However, knowledge regarding identification of PTSD in this population is limited. The aim of this study was to investigate clinical experience regarding PTSD and trauma assessment in individuals with co‐occurring ASD and ID. Method: Interpretative phenomenological analysis was used to explore experiences of identifying PTSD in this population among 18 mental health clinicians working with ASD and ID. Results: Informants viewed PTSD in individuals with ASD and ID as equivalent to PTSD in the general population, but with causes and expressions potentially differing. Several factors were described to contribute to challenges in identification. Conclusions: Trauma may have severe impact in individuals with ASD and ID. Multidimensional, individualized assessment strategies seem necessary to recognize PTSD or trauma‐related symptoms in this population. [ABSTRACT FROM AUTHOR]
