Validez y confiabilidad de la Batería Luria Inicial para identificar alteraciones neuropsicológicas en niños cubanos.

Introduction: The Initial Luria Battery has had a clinical utility of impact in Cuba. Investigations demonstrate the effectiveness of the instrument to organize diagnosis strategies and neuropsychological rehabilitation in school children (between 5 and 6 years) with delay in the acquisition of superior psychological functions. Methods: A study descriptive longitudinal correlational of panel intends to determine the validity of the Initial Luria battery to identify neuropsychological alterations in the school age in a Cuban population with backwardness in the process of acquisition of the superior psychological functions. It calculates the coefficient of Cronbach, it defines explained variance percent and it shows prediction capacity battery for detect executive dysfunctions three years after application. It applied SESH 1.1 test (Evaluation and Pursuit System of the Hypothyroidism patient). The study included 126 children: 89 with ADHD, 25 with immaturity neuropsychological signs and 12 with neurological risk factors for early hypoxia Results: The instrument has a smaller internal consistency that the Spanish norms (0.92), but it maintains a reliable statistical value (0.82). The percent of the variance explains to 58.64 % comparative with the original 59.73 % and with 62.50 % compared with the Mexican (68,51 %). The executive factor of the battery turned out to be a strong predictor of the executive functions. Conclusions: The instrument is valid for to identify neuropsychological alterations in Cuban children with attention deficit with hyperactivity, neurological risk associated to early hypoxia and immaturity neuropsychological signs. It presents a strong value predictor of executive alterations after three years of applied the instrument. [ABSTRACT FROM AUTHOR]
