Theory of mind in children with attention deficit hyperactivity disorder

Abstract

Introduction. Theory of mind (TM) is involved in social cognition, as it evaluates our ability to impute our mental states to the others in order to predict and explain behaviour. In the literature, it has been noticed that children with attention deficit hyperactivity disorder (ADHD) show some impairments of TM when compared with children not neurodevelopmental impaired. Our goal in this study was to compare the TM in two groups: schooler children with normal development and schooler children with ADHD. Subjects and methods. A total of 35 children, aged between 6 and 12 years, were recruited: 17 with ADHD and 18 not neurodevelopmental impaired. TM was evaluated using an assessment method validated for the Portuguese population: Turtle on the Island-Battery of Assessment of Executive Functions in Children. Results. We obtained two comparable groups concerning sociodemographic data. There were no significant differences between the two groups regarding TM. Conclusion. The TM assessment in Portuguese children did not reveal significant impairment regarding this cognitive skill in children with ADHD.
