Abstract (English): 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-Sánchez 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 (a > 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. [ABSTRACT FROM AUTHOR]
Abstract (Spanish): Objetivo: Describir las propiedades psicométricas de la fase de piloteo de la Batería para la Evaluación de las Dispraxias, en una muestra de 200 niños mexicanos, compuesta exclusivamente por participantes neurotípicos entre 2 y 6 años. Métodos: La prueba se fundamentó con los principios teóricos de la dispraxia propuestos por Castillo-Sánchez Lara. Los participantes fueron seleccionados mediante muestreo por conveniencia procedentes de escuelas públicas y privadas en tres estados de México. Se construyeron cinco escalas según grupos de edad (2, 3, 4, 5 y 6 años). Cada edición evaluó ocho áreas clave: somatosensorial (procesamiento de estímulos internos y externos), propiocepción (ubicación del cuerpo en el espacio), esquema corporal (conciencia global del cuerpo), control postural (control del cuerpo en movimiento y reposo), praxia orolinguofacial (movimientos voluntarios de músculos faciales y orolinguales), praxia constructiva (coordinación visomotora y espacial), somatopraxia (ejecución precisa de movimientos voluntarios) y exploración visual (búsqueda visual activa). Resultados: Los análisis estadísticos se realizaron mediante el coeficiente alfa de Cronbach. Los resultados mostraron niveles de confiabilidad aceptables en la mayoría de las escalas (a > 0.7). Conclusiones: La batería para la Evaluación de las Dispraxias demostró adecuadas propiedades psicométricas en una muestra de preescolares y en la detección de alteraciones en los componentes subyacentes. Los resultados respaldan el desarrollo e implementación de programas en rehabilitación neuropsicológica. [ABSTRACT FROM AUTHOR]
