Abstract

The aim of the present study was to investigate the psychometric properties of the Spanish version of the Adult Executive Functioning Inventory (ADEXI) in adults with Autism Spectrum Disorders (ASD) and Intellectual Disability (ID). A total of 121 adults with ASD and ID were recruited and informant ratings on the ADEXI were collected to investigate the factor structure, as well as reliability and validity. The results showed that we could replicate the two-factor structure (i.e., working memory and inhibition) that had been found in a previous study of adults with Attention Deficit Hyperactivity Disorder (ADHD). The two ADEXI subscales were shown to have high internal consistency and significant associations were found between the ADEXI and the Dysexecutive Questionnaire (DEX), another executive function rating instrument. Conclusively, the ADEXI appear to be a valid instrument for assessing executive function deficits in adults with ASD and ID.
