Abstract:
〈 b 〉 〈 i 〉 Introduction: 〈 /i 〉 〈 /b 〉 Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) share overlapping symptomatology, particularly with regard to social impairments (including peer relationship difficulties), and they frequently co-occur. However, the nature of their co-occurrence remains unclear. Therefore, the current study aimed to examine the nature of the transdiagnostic link between ASD and ADHD from a symptomatological point of view measured with the Autism Diagnostic Observation Schedule (ADOS Module 3) and the Autism Diagnostic Interview-Revised (ADI-R). 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 We analyzed the social and nonsocial ASD symptom domain scores from both diagnostic instruments in 4 clinically referred groups (i.e., ASD, ADHD, ASD + ADHD, and no psychiatric diagnosis) without other co-occurring mental disorders using a two-by-two full-factorial MANOVA design with the factors ASD (yes/no) and ADHD (yes/no). 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 We found no ASD by ADHD interaction effects across all symptom domain scores of ADOS and ADI-R, except for ADOS 〈 i 〉 imagination/creativity 〈 /i 〉 . There were only main effects of the factor ASD but no main effects of ADHD. Follow-up contrasts showed that exclusively, ASD had an impact on the measured symptomatology in case of co-occurring ASD + ADHD. 〈 b 〉 〈 i 〉 Conclusion: 〈 /i 〉 〈 /b 〉 Overall, the results support an additive model of the symptomatology across areas of communication, social interaction, and stereotyped behaviors and restricted interests in case of the co-occurrence of ASD and ADHD when assessed with ADOS/ADI-R. Thus, one can assume that the phenotypic overlap of ASD + ADHD may be less complicated than suspected – at least with regard to ASD symptomatology – and that in the presence of ADHD, ASD symptomatology is generally well measurable with best-practice diagnostic instruments.
