Do ADHD and SLD children differ in executive functions and behavioural problems? A comparative study

Abstract

It is well-known that children with attention-deficit/hyperactivity disorder (ADHD) and specific learning disorder (SLD) often exhibit behavioural and emotional problems. However, little is known about how these problems compare between the two groups of children. This study sought to fill this gap in knowledge by comparing the executive functions and behavioural–emotional problems of children with ADHD, SLD and typically developing children. For this study, 94 children were recruited through purposeful sampling (ADHD = 23, SLD = 30 and TD = 41). All participants were screened based on WISC-IV. Subsequently, participants were administered executive functions and behavioural problems questionnaires. The analysis of the data using MANOVA and Scheffe post hoc pairwise shows that children with ADHD and SLD had significantly higher scores on measures of executive function impairment than typically developing children. Our study revealed that children in the ADHD group scored significantly higher in social problems, aggressive behaviours, AD/HD problems, ODD, conduct problems and externalizing problems sub-tests. Conversely, the LD group demonstrated higher scores in the anxiety problems sub-test. Furthermore, Our study demonstrated that children in the ADHD group scored significantly higher in the following sub-tests: metacognition, inhibit, shift, bri, shift and emotion control. In contrast, the LD group exhibited higher scores in the initiate sub-test. In addition, the two groups of children with disorders also exhibited more behavioural–emotional problems than typically developing children. These findings suggest that ADHD and SLD are associated with impaired executive function and increased behavioural–emotional problems. These findings have implications for the assessment and treatment of these disorders.
