Development and pilot validation of a Dyspraxia Evaluation Battery

Objective:The objective of this study was to describe the psychometric properties of the pilot phase of the Battery for the Assessment of Dyspraxia in a sample of 200 Mexican children, composed exclusively of neurotypical participants between 2 and 6 years of age.Methods: The test was developed based on the theoretical principles of dyspraxia proposed by Castillo-Snchez Lara.Participants were selected through convenience sampling from public and private schools in three Mexican states.Five scales were constructed according to age groups (2, 3, 4, 5, and 6 years). Each version assessed eight key areas: somatosensory (processing of internal and external stimuli), proprioception (body position in space), body schema (global body awareness), postural control (body control in motion and at rest), orolingual-facial praxis (voluntary movements of facial and orolingual muscles), constructive praxis (visuomotor and spatial coordination), somatopraxis (precise execution of voluntary movements), and visual assessment (active visual search).Results: Statistical analyses were performed using Cronbach's alpha coefficient.The results showed acceptable reliability levels in most scales ( > 0.7).Conclusions: The battery for the assessment of dyspraxia demonstrated adequate psychometric properties in a preschool sample and in detecting alterations in underlying components.The findings support its application in the development and implementation of neuropsychological rehabilitation programs.
