Validez de la escala corta de Liderazgo Transformacional en el marco de la Auditoría del Sistema Humano en cuatro países Europeos (HSA-TFL) Validity of the Human System Audit Transformational Leadership Short Scale (HSA-TFL) in four European countries Recibido: julio 19 de 2010 Revisado: septiembre 3 de 2010 Aceptado: septiembre 10 de 2010 * Rita BeRgeR MontseRRat Yepes Juana góMez Benito santiago QuiJano Universidad de Barcelona, España ** Felix BRodBeck Ludwig-Maximillians Universität, München, Alemania ResuMen La necesidad de las empresas de evaluar el liderazgo transformacional en un contexto amplio y combinado con rendimiento de calidad, requiere instrumentos cortos y, al mismo tiempo, basados en evidencia científica. El objetivo de este estudio es analizar la validez (convergente, de constructo y de criterio) de la escala corta del Liderazgo Transformacional, usada por la Auditoria del Sistema Humano (short HSA-TFL). La comparación con el Multifactor Leadership Questionnaire (MLQ-5X) aportó valores de alta validez convergente. El análisis factorial exploratorio con empleados del sector sanitario en España (N = 625) del HSA-TFL, sugiere una estructura unifactorial, que fue confirmada mediante análisis factorial confirmatorio, realizado con otras tres muestras de empleados del sector hospitalario de varios países Europeos (N = 776). Asimismo, los resultados muestran, en los cuatro países, una relación positiva del HSA-TFL con el rendimiento subjetivo (validez de criterio). En conclusión, la versión breve del HSA-TFL es válida para el análisis del liderazgo transformacional. Palabras clave autores Validez de constructo, escala corta, liderazgo transformacional.
