Background/ObjectiveMotor coordination impairment is common in children with neurodevelopmental
disorders such as autism spectrum disorder (ASD) and attention
deficit/hyperactivity disorder (AD/HD). The purpose of this study was to
investigate the relationship between motor coordination, cognitive ability,
and academic achievement in Japanese children with neurodevelopmental
disorders.MethodsThirty-four school-age (6–12 years old) children with neurodevelopmental
disorders and 34 age-matched typically developing (TD) children were
recruited in this study. Correlations between the scores of the Movement
Assessment Battery for Children-2 (M-ABC2) and the Kaufman Assessment
Battery for Children — Second Edition (K-ABCII) that assesses cognitive
abilities, and academic achievement were analyzed.ResultsThe children with neurodevelopmental disorders obtained a lower total score
and all component scores on M-ABC2 compared to the TD children. In children
with neurodevelopmental disorders, M-ABC2 Manual Dexterity score was
significantly correlated with K-ABCII Simultaneous Processing (r = .345, p =
.046), Knowledge (r = .422, p = .013), Reading (r = .342, p = .048), Writing
(r = .414, p = .017), and Arithmetic (r = .443, p = .009) scores. In
addition, M-ABC2 Balance score was significantly correlated with K-ABCII
Learning (r = .341, p = .048), Writing (r = .493, p = .004), and Arithmetic
(r = .386, p = .024) scores.ConclusionThese findings stress that it is essential to accurately identify motor
coordination impairments and the interventions that would consider motor
coordination problems related to cognitive abilities and academic
achievement in Japanese children with neurodevelopmental disorders.
Background
The evaluation of a child tends to differ between the mother and father regardless of whether the child has a disability or not, although parents have key information about the behavioral characteristics of the child. The number of reports in Japan, however, is limited. We, therefore, investigated the relationship between the parenting stress experienced by parents of non‐clinical preschool children and the children's behavioral characteristics.
Method
The subjects were 83 pairs of mothers and fathers with non‐clinical children in kindergarten and nursery school (average age, 59.1 ± 13.0 months; 36 boys, 47 girls). The study was conducted using the Parenting Stress Index–Short Form (PSI‐SF) and the Strengths and Difficulties Questionnaire (SDQ).
Results
There was no difference in the PSI‐SF scores between mothers and fathers, but hyperactivity/inattention, peer relationship problems, and the total score of the SDQ were significantly higher in fathers. On multiple regression analysis, parenting stress experienced by fathers was significantly related to hyperactivity/inattention, while parenting stress experienced by mothers was significantly related to peer relationship problems and emotional symptoms.
Conclusion
Children's behavioral characteristics related to parenting stress differ between mothers and fathers.
Motor coordination abilities are related to cognitive abilities and academic achievement in children with neurodevelopmental disorders. However, the similarities and differences of these relationships in children with autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (AD/HD) have not been explored. The purpose of this study was to investigate the relationship between motor coordination abilities, cognitive abilities, and academic achievement in Japanese children with ASD and AD/HD. Participants included 20 children with ASD, 20 children with AD/HD, and 20 typically developing children, matched for age and gender. Their motor coordination abilities were assessed with the Movement Assessment Battery for Children-2 (MABC-2). Furthermore, cognitive ability and academic achievement were assessed with the Kauffman Assessment Battery for Children-II (K-ABCII). Results demonstrated that the MABC-2 Total score significantly correlated with the K-ABCII Simultaneous processing, Planning, Total cognitive ability, Writing and Arithmetic scores in children with ASD. However, in children with AD/HD, there was no significant correlation between MABC-2 and K-ABCII subscale scores. The results of this study indicated that the relationship between motor coordination ability, cognitive ability, and academic achievement differs between ASD and AD/HD. This difference might indicate the non-similarity of neurological characteristics and encourage consideration for an approach that accommodates the features of neurodevelopmental disorders in children.
