Validation and Translation of the Greek Version of the “DCDDaily-Q-GR” Questionnaire

Abstract

The origin of Developmental Coordination Disorder (DCD) has not been clarified yet. DCD is considered as a movement disorder that may strongly affect child’s Activities of Daily Living (ADL). Reliable evaluation tools for young DCD are importantly useful. This study aimed to translate and validate the Developmental Coordination Disorder Daily Questionnaire (DCDDaily-Q) into Greek. The current validation study reports on the translation, cultural adaptation and validation of the Greek. The total sample consisted of 191 children (age 5 - 8 years) and their parents who completed the questionnaire as a reference group. The participants were randomly divided into two groups. The first group (100 parents) completed only the DCDDaily-Q. The second group consisted of 91 parents who completed the DCDDaily-Q, while their children were additionally evaluated with the Movement Assessment Battery for Children 2 (MABC-2). Then two groups were created that included (25) children with DCD and a control group 30 children with typical developmental. The results were analyzed was performed using IBM SPSS statistics 24.0 (a = 0.05). The internal consistency of the Greek version of the DCDDaily-Q was assessed (Cronbach’s α = 0.86). High test-retest reliability for all items and good diagnostic performance for identifying children with DCD were achieved with a sensitivity of 0.76 and a specificity of 0.67. The Greek version of DCDDaily-Q was proved to be a reliable and valid screening tool for ADL assessment in 5 to 8 year old children with DCD; offering an easy to use and economical tool in the Greek healthcare system.
