We employed a clinical sample of young children with ASD, with and without intellectual disability, to determine the rate and type of psychiatric disorders and possible association with risk factors. We assessed 101 children (57 males, 44 females) aged 4.5–9.8 years. 90.5 % of the sample met the criteria. Most common diagnoses were: generalized anxiety disorder (66.5 %), specific phobias (52.7 %) and attention deficit hyperactivity disorder (59.1 %). Boys were more likely to have oppositional defiant disorder (OR 3.9). Higher IQ was associated with anxiety disorders (OR 2.9) and older age with agoraphobia (OR 5.8). Night terrors was associated with parental psychological distress (OR 14.2). Most young ASD children met the criteria for additional psychopathology.
