    Abstract:
    BACKGROUND: The revised version of the Developmental Coordination Disorder Questionnaire (DCDQ'07) is a parent questionnaire designed to identify Developmental Coordination Disorder in 5-15-year-old children. AIM: The aim of this study was to carry out the translation and cross-cultural adaptation of the DCDQ'07, to examine psychometric properties, and to define the cut-off scores of the Arabic-Lebanese version of the questionnaire (DCDQ-AL). METHOD: 38 parents of children with and without motor difficulties participated in the translation and cross-cultural phase. As for the validation phase and the study of the psychometric properties, a total of one hundred and twenty-four typically developing children (N=124) aged between 5 and 15 years were recruited through schools in different districts across Lebanon, whereas the clinical sample (N = 56) of children with motor difficulties was recruited via psychomotor rehabilitation centers in Beirut and psychomotor therapists working in private clinics across the country. This study used the Movement Assessment Battery for Children - second edition (MABC-2) motor test developed to classify children according to their degree of motor impairment. RESULTS: For test-retest reliability and inter-rater reliability, excellent Intraclass Correlation Coefficients (ICC) were shown with values of 0.94 and 0.9, respectively. The internal consistency value for the DCDQ-AL was high (Cronbach's alpha = 0.947). Correlations between the DCDQ-AL scores and Movement Assessment Battery for Children (MABC-2) show adequate convergent validity (ρ = 0.65, p < .001). Differences in DCDQ-AL scores between children with and without motor difficulties (p < .001) provide clear evidence of discriminative validity. The Lebanese cut-offs are very similar to the Canadian version, except for the 5-7 age band. The DCDQ-AL shows a sensitivity of 0.91 and specificity of 0.77. The adapted questionnaire showed solid psychometric properties, allowing us to conclude that the DCDQ-AL can be used to support a diagnosis of DCD. CONCLUSION: The results provide evidence that the DCDQ-AL is a valid clinical screening tool for DCD that can assist Arabic speaking professionals in screening children aged 5-15 years old who are at risk of having DCD.
