The relationship between fine and gross motor ability, self-perceptions and self-worth in children and adolescents.

The present study examined the impact of fine and gross motor ability on self-perceptions of male and female children and adolescents. Participants were compared across age group, sex, and level of motor ability. When intercorrelations between self-perceptions were taken into account, the level of movement ability was found to impact upon perceived athletic competence and scholastic competence. When movement was considered in terms of fine and gross motor ability, it was found that those with higher perceived scholastic competence were in the younger group and had better fine motor skills. Furthermore, those with greater perceived athletic competence were also in the younger group, were predominantly male and had better gross motor skills. The types of self-perceptions that influenced self-worth were dependent on the level of motor ability of the participants and varied according to their sex. The implications of these findings are discussed with reference to the necessity to assess specific types of motor deficit when tailoring intervention strategies for children with motor disorders, particularly within the academic setting.

Timing and force control in boys with attention deficit hyperactivity disorder: subtype differences and the effect of comorbid developmental coordination disorder.

This study examined the motor and performance outcomes of boys with subtypes of attention deficit hyperactivity disorder (ADHD) (DSM-IV, [American Psychiatric Association, Diagnostic and statistical manual of mental disorders, 4th ed., Washington, DC, 1994]). It also examined the differences between boys with a single diagnosis of ADHD versus those who have the dual categorisation of ADHD and developmental coordination disorder (DCD). The participants were 157 boys, aged 7.70-12.98 years recruited from a community sample. Parent report was used to classify 143 boys into either a comparison group or one of the three DSM-IV ADHD subtypes. Participants were given a battery of tests that included the Movement Assessment Battery for Children [Movement Assessment Battery for Children, Psychological Corporation/Harcourt Brace-Jovanovich, New York, 1992], the Wechsler Intelligence Scales for Children--Third Edition [Manual for the Wechsler Intelligence Scale for Children, Psychological Corporation, New York, 1992] and a finger tapping task targeting motor processing, preparation, and execution. Boys with subtypes that included inattentive symptomatology had significant difficulties with timing, force output and showed greater variability in motor outcomes. Boys with the comorbid condition (i.e., ADHD and DCD) had particular difficulty with force control. These outcomes identify a need for increased recognition of the clinical and research implications of the relationship between ADHD and motor dysfunction. This potentially impacts on assessment, intervention, theoretical modelling and the general interpretation of cognitive abilities research with children with ADHD.
