Background:
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.
Aims:
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.
Methods:
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 RESULTS: 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, η2 = 0.005) and gender (H(1) = 2.75, p = 0.09, η2 = 0.005) were depicted for the LDCDQ-GR final score.
Conclusion:
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.

Equations of Motion: Rectangular Coordinates and Cylindrical Coordinates
When a particle moves relative to an inertial frame, the equations of motion can be expressed using rectangular components. If the motion is confined to the x-y plane, the equations having the x and y coordinates only can be used to simplify the mathematical representation.
However, when particles...
