Preliminary psychometric evaluation of the Greek little developmental coordination disorder questionnaire (LDCDQ-GR)

Developmental Coordination Disorder (DCD) is a multifactorial motor disorder that significantly impacts a child’s activities of daily living and academic skills. Identifying signs of DCD early is essential to enable timely support and reduce the risk of long-term difficulties. This cross-sectional study aimed to further investigate the psychometric properties of the Greek version of the Little Developmental Coordination Disorder Questionnaire (LDCDQ) by carrying out appropriate analyses in a convenience sample of 3- to 5- year old children in Greece. A total of 362 preschool children aged 3–5 years old from 39 municipal kindergartens in Thessaloniki, Greece participated in this study. Parents filled out the Greek LDCDQ. Internal consistency of the LDCDQ-GR was determined by Cronbach’s alpha. Construct validity was investigated using factor analysis Internal consistency of the LDCDQ-GR was 0.88. Factor analysis resulted in three factors (Locomotor, Fine motor and General Coordination skills). No effects of age (H(2) = 3.93, p = 0.14, η 2 = 0.005) and gender (H(1) = 2.75, p = 0.09, η 2 = 0.005) were depicted for the LDCDQ-GR final score. LDCDQ-GR appears to be a reliable and well-structured questionnaire for identifying preschool-aged (3–5 years old) children in Greece who may be at risk for DCD. • Accurate screening tools are crucial for identifying young children at risk of DCD. • LDCDQ-GR showed high internal consistency across preschool age groups. • No significant effects of age or gender on LDCDQ-GR total scores were found. • PCA revealed a stable 3-factor structure aligned with motor skill domains, revealing in consistencies in subcategories.
