Insights
Children with anxiety disorders (AnxDs) show significant motor impairments, similar to those with attention deficit/hyperactivity disorder (ADHD). Motor difficulties in AnxDs often impact daily life, highlighting the need for motor assessments.
Area of Science:
- Child Psychology
- Neurodevelopmental Disorders
- Movement Science
Background:
- Anxiety disorders (AnxDs) are prevalent in children, often co-occurring with other conditions like attention deficit/hyperactivity disorder (ADHD).
- Motor skill deficits have been noted in ADHD, but their prevalence and impact in AnxDs are less understood.
- Understanding motor function in AnxDs is crucial for comprehensive assessment and intervention.
Purpose of the Study:
- To investigate the frequency and severity of motor impairments in children with AnxDs.
- To compare motor abilities of children with AnxDs to those with ADHD, comorbid AnxDs and ADHD, and typically developing controls.
- To determine if motor impairment in AnxDs affects daily living activities.
Main Methods:
- Participants included 141 children (7-13 years) with diagnosed AnxDs, ADHD, comorbid AnxDs and ADHD, or no diagnosis (controls).
- Diagnoses were confirmed using the Schedule for Affective Disorders and Schizophrenia for School-Aged Children (Kiddie-SADS).
- Motor ability was evaluated using the Movement Assessment Battery for Children (M-ABC).
Main Results:
- Children with AnxDs demonstrated significantly higher motor impairment scores on the M-ABC compared to controls.
- No significant differences in motor impairment were found between children with AnxDs, ADHD, or comorbid conditions.
- Nearly half (46%) of children with AnxDs scored below the 5th percentile on the M-ABC, indicating clinically significant motor deficits.
Conclusions:
- Motor impairment is a common feature in children with anxiety disorders, comparable to that seen in ADHD.
- These motor deficits in AnxDs can be severe enough to interfere with daily activities.
- Routine assessment of motor function should be considered in the clinical evaluation of children with anxiety disorders.
Abstract:
This study examined the frequency and degree of motor impairment in referred children with anxiety disorders (AnxDs), compared with children with attention deficit/hyperactivity disorder (ADHD), children with comorbid AnxDs and ADHD, and nonreferred controls. All participants (n=141; 90 males, 51 females; mean age: 10 years, 1 month; range: 7-13 years) had an IQ greater than 70. Diagnoses of mental disorders were established using the Schedule for Affective Disorders and Schizophrenia for School-Aged Children (Kiddie-SADS). Motor ability was assessed using the Movement Assessment Battery for Children (M-ABC). We found that children with AnxDs exhibited significantly higher total impairment scores on the M-ABC than controls, but were not significantly different from children with ADHD or children with comorbid AnxDs and ADHD. All clinical groups exhibited similar profiles of motor impairment. A total of 19 (46%) children with AnxDs scored below the 5th percentile on the M-ABC, indicating that motor function is impaired in many children with AnxDs to a degree that probably interferes with their activities of daily living. These results support the notion that assessment of motor function is important in understanding the daily challenges of children with AnxDs.

These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
Anxiety: Overview
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.
