Neurodevelopmental correlates of behavioural and emotional problems in a neuropaediatric sample

Abstract Most research does not address the overlap between neurodevelopmental disorders when investigating concomitant mental health problems. The purpose of the present study was to examine the association of intellectual disability (ID), autism spectrum disorder (ASD), and attention-deficit/hyperactivity disorder (ADHD) with the presence of behavioural and emotional problems after controlling for other well-known correlates and risk factors. The sample included 4- to 18-year-old children who attended neuropaediatric clinics ( N  = 331). After controlling for adversity, age, gender, other developmental/neurological disorders, parental emotional problems, and parenting strategies, the presence of ADHD but not ASD or ID was uniquely associated with behaviour problems. Neither ADHD nor ASD nor ID was significantly associated with emotional problems after controlling for other risk factors. However, ADHD, ASD and behavioural/emotional disorders but not ID were significantly associated with functional impairment in everyday activities after controlling for other risk factors. Because children with neurodevelopmental disorders have complex needs, a holistic approach to diagnosis and interventions is highly warranted, including the assessment and treatment of behavioural and emotional disorders.
