Psychometric Properties of the French European Little Developmental Coordination Disorder Questionnaire (LDCDQ-FE): A Pilot Study

Abstract

Aims. The Little Developmental Coordination Disorder Questionnaire (LDCDQ) is a parental questionnaire designed to identify preschool children at risk of Developmental Coordination Disorder (DCD). This study aimed to translate and cross-culturally adapt the LDCDQ for French European informants (Little Developmental Coordination Disorder Questionnaire -French European [LDCDQ-FE]) and to undertake a pilot examination of its psychometric properties on a French sample. Methods. A thorough process of cultural adaptation was completed. The psychometric properties were examined with a sample of 154 French children aged to 5y11m (control=121; clinically referred=33). A sub-group of 34 children was assessed using the MABC-2 to measure convergent validity. Results. Principal component analysis demonstrated a fourcomponent structure, accounting for 67.5% of the variance. Internal consistency was acceptable to good (α=0.74-0.89). Significant correlation between the LDCDQ-FE and the MABC-2 total scores showed convergent validity. Discriminant validity was supported by significant score differences between the clinically referred and a matched control sub-group. Using ROC curves, a cut-off of 67 was proposed for a sensitivity of 81.3% and a specificity of 77.8%. Conclusions.Results show initial evidence of the psychometric properties of the LDCDQ-FE and are encouraging of its use to identify young preschoolers at risk for DCD. In future studies, the testretest reliability should be investigated, and study sample sizes expanded.

“…The Little Developmental Coordination Disorder Questionnaire-French European (LDCDQ-FE)24 25 and for children over 7 years of age, the Developmental Coordination Disorder Questionnaire-French European (DCDQ-FE)26 assess DCD. Scales include 15 items grouped into three domains: control during movement, fine motor function and writing, and global coordination.…”

Assessing the usefulness of the Little Developmental Coordination Disorder Questionnaire-Chinese in Chinese preschoolers: a sex-and age-specific analysis

“…As a downward extension of the DCDQ'07, the Little Developmental Coordination Disorder Questionnaire (LDCDQ) was originally developed in Hebrew to identify motor development and coordination difficulties of young preschoolers aged 3-and 4-years (Rihtman et al, 2011). The original LDCDQ demonstrated sound psychometric properties (Rihtman et al, 2011), and since its initial publication, the LDCDQ has been adapted for use in multiple countries including -among others -the Netherlands (Cantell et al, 2018), South Africa (Venter et al, 2015), France (Jover et al, 2013), and Canada (Wilson et al, 2015). These studies have demonstrated the need for a variety of culture-and context-specific amendments, including adjustment of item phrasing and detail, the inclusion of alternate item examples, age-range extension to include 5-year-old children (where children begin schooling later), and the adoption of alternate sub-scores structures.…”
