RESUMEN El objetivo del estudio es disenar y validar un instrumento de observacion para conocer los Indicadores de Rendimiento Competitivo en Futbol a 5 para personas ciegas a traves de jueces expertos. La muestra se compuso por 12 entrenadores expertos en Futbol a 5. Tras la realizacion de un estudio preliminar, el IOLF5C quedo estructurado en dos partes: acciones basicas durante el lanzamiento a porteria en situaciones de juego, y durante el penalti. La validez de contenido se realizo a traves de la V de Aiken y sus intervalos de confianza. Para comprobar la consistencia interna del instrumento se empleo α de Cronbach. Los resultados indicaron que el IOLF5C dispone de niveles optimos de validez obteniendo valores superiores a 0,875 en todos los items durante el juego y 0,96 en penalti. La consistencia del instrumento fue de 0,894. Por tanto, el IOLF5C es un instrumento valido y fiable. PALABAS CLAVES : entrenador, validacion, futbol a 5, ciegos, V de Aiken, α de Cronbach. ABSTRACT The aim of this study was to design and validate an observational instrument to identify essential competitive performance indicators in Football 5-a-Side forblind and partially sighted players through the assistance of expert evaluators. The sample was comprised of twelve Football 5-a-Side expert coaches. After a preliminary study, the OLF5C instrument was structured to include two groups of actions: basic actions during shots on goal in game situations and shooting actions penalty situations. Aiken's V statistic and confidence interval values were used to assess the content validity and Cronbach' value was used to assess the internal consistency of the instrument. Results indicated that the IOLF5C has good validity indices with obtained values reaching .875 in all items during game situations and 0.96 on penalty shot actions. The overall level of instrument consistency was .894. The IOLF5C is considered to be a valid and reliable instrument. KEYWORDS : coach, validation, Football 5-a-Side, blind, Aiken's V, Cronbach's α.
