The Developmental Coordination Disorder Questionnaire (DCDQ’07) is an instrument for screening children between 5 and 15 years of age. Although it is popular, this instrument has not been adapted for use with Turkishchildren, and there is no valid similar screening tool in Turkey. Thus, this study aimed to provide a cross-culturaladaptation of the DCDQ’07 for Turkishchildren. We performed the translation process using well-established cross-culturaladaptation guidelines, and we recruited 736 parents (361 males, 375 females) of typically developing children with a mean (M) age of 9.27 years (standard deviation = 2 years 5 months, range: 5.0–14.9 years). We determined the internal consistency of the questionnaire by item and total score correlations, Cronbach’s α and item-deleted Cronbach’s α. Intraclass correlationcoefficients were used to determine test–retest reliability after an interval of 5 days. The Cronbach’s α of the TurkishDCDQ’07 was .890 for the total questionnaire. All the item-deleted Cr...
