Cross-cultural validation of the Brazilian Little Developmental Coordination Disorder Questionnaire (LDCDQ-BR) for preschool children

Abstract

Introduction: Motor difficulties associated with Developmental Coordination Disorder (DCD) are frequently apparent before the accepted diagnostic age of 5. Tools to support identification of DCD markers would allow provision of early intervention to reduce negative sequelae. Objective: Establish psychometric properties and define preliminary cut-off scores for the Brazilian Little Developmental Coordination Disorder Questionnaire - Brazil (LDCDQ-BR). Methods and procedures: Parents of 3- and 4-year-old children (n=312; 154 girls) from Belo Horizonte/MG, Brazil, completed the LDCDQ-BR, the Brazil Economic Classification Criterion and a demographic  questionnaire. One sub-set of children (n=119) was assessed with the Movement Assessment Battery for Children–2 nd Edition; another sub-set (n=77) completed the LDCDQ-BR a second time. Results: Rasch analysis indicated good item functioning with only one erratic item, suggesting unidimensionality. Item calibration reliability was excellent (0.97), children’s measures reliability was low (0.72), but implying separation of 2.46 motor ability levels. Significant, low correlations were found between the LDCDQ-BR and MABC-2 (r=0.30, p<0.01). Test-retest reliability was 0.77 (total score) and 0.44-0.78 (individual items). ROC curve analysis revealed sensitivity of 68% at a cut-off score of 64. Conclusion: The LDCDQ-BR shows promising psychometric properties to support early identification of DCD.
