Relationship between Mastery Motivation and Sensory Processing Difficulties in South Korean Children with Developmental Coordination Disorder

The aim of this study was to identify the correlation between mastery motivation and sensory processing difficulties among South Korean children with developmental coordination disorder (DCD). Ninety-nine children aged 4–7 years with DCD participated. The Dimensions of Mastery Questionnaire was used to assess the mastery motivation of the children, and the Short Sensory Profile was used to assess the children’s sensory processing difficulties. All subjects showed lower mastery motivation and definite differences in sensory processing. Mastery motivation was significantly correlated with sensory processing (r=−0.34, p=0.01). Mastery motivation predicted 41.1% of the sensory processing. In particular, a negative reaction to failure in mastery situations scale (p<0.01) and general competence compared to peers scale (p
