Abstract
  • Current prevalence statistics suggest 1 in 88 children are diagnosed with autism spectrum disorder (ASD) (CDC, 2012). ASDs are pervasive developmental disorders characterized by social communicative deficits and restricted interests and behaviors (APA, 2000). Children with ASD also display deficits in motor skills (Green et al., 2002: Pan, Tsai, & Chu, 2009; Provost et al., 2007). Prior research suggests that the developmental domains of cognition and language are related to both the motor and the social domains (Chen & French, 2008; Thelen, 2000). Yet there is a paucity of research examining the relationship of motor skills and social skills in young children with ASD. PURPOSE: The purpose of this study was to examine the relationship of social and motor skills in young children with autism. METHODS: The participants of this study included young children with and without ASD between the ages of 2-7 years old. All participants were administered The Mullen Scales of Early Learning (MSEL), a valid and reliable measure of development in young children, and the Peabody Developmental Motor Scales (2nd Ed.) (PDMS-2), which is a standardized tool to measure the motor skills in children up to 5 years of age. Raw scores for fine, gross, and total motor components were used in data analysis of motor skills. Evaluations of social skills were assessed using the Autism Diagnostic Observation Schedule- calibrated severity scores (CSS) (Gotham et al., 2007; Gotham et al., 2009). RESULTS: As expected there were no statistical differences between groups for non-verbal IQ (p = 0.49). However, statistical differences did exist for social skills (p < 0.01) and motor skill (p < 0.01) between groups. All children with ASD scored lower than children without ASD on motor scores, however this difference was not statistically different. No correlations were found between motor and social skills within groups. However, a moderate relationship was seen between grasping motor skills and social skills (r = -0.50) when observing the total sample. CONCLUSION: While significance was not found in the difference of motor performance between groups, children with ASD scoring lower in each motor category supports the perspective that children with ASD, who by nature of the disorder, have lower performance of social skills also have lower performance of motor skills than their peers without ASD. Having a small sample and large variance in performance of motor skills in our participants may have contributed to the lack of relationship found between motor and social skills for both groups. Therefore, further investigations of the questions in this study using larger sample sizes need to be conducted.
