The Effect of Neurodevelopmental Disorders Characteristics on Aspects of Social Functioning

The purpose of this study was to estimate the extent to which neurodevelopmental disorders (NDD's) symptoms (motor, sensory, attention and executive function) are associated with aspects of social function among school aged children.

This cross-sectional study included 39 children aged 6-9 years old (71.8% boys) who were referred to child development centers due to motor, sensory, and/or cognitive difficulties. The parents completed NDD's symptoms questionnaires: Developmental Coordination Disorder Questionnaire; Child Sensory Profile-2; Attention Deficit Hyperactive Disorder (ADHD) Rating Scale and the Behavior Rating Inventory of Executive Function. They also completed the Social Skills Improvement System and a social participation measure.

Analysis demonstrated low to moderate correlations between social functioning aspects and the majority of NDD's symptoms. Executive functioning was the only predictor of social skills and social participation and accounted for most of the variability of behavioral problems, alongside a small contribution of ADHD symptoms.

The findings contribute to the accumulating body of knowledge regarding social abilities of children with NDD's and suggest new information as to the effect of executive functions in this domain. Along with conducting a routine evaluation of social skills among children suspected to have NDD's, executive functions should also be comprehensively evaluated.
