Validity of the Developmental Coordination Disorder Questionnaire’ 07 and Its Association with Physical Activity in Young Children with Developmental Disabilities

OBJECTIVES The purposes of the current study were to examine the construct and predictive validity, and reliability of the developmental coordination disorder questionnaire’ 07 (DCDQ’ 07) for young children with developmental disabilities (DD).METHODS 135 parents of young children with DD completed an online questionnaire which consisted of demographic information, the DCDQ’ 07, and a physical activity behavior questionnaire. A one-way analysis of variance was conducted to evaluate motor difficulties across different types of young children with DD. Exploratory factor analysis and Cronbach’s alpha were used to examine construct validity and reliability of the DCDQ’ 07. Moreover, hierarchical multiple regression analysis was used to examine the association between the DCDQ’ 07 scores and physical activity behaviors in young children with DD.RESULTS The one-way analysis of variance indicated that the DCDQ’ 07 scores were significantly different across different types of young children with DD = 6.66, p
