Psychometric Properties of the Spanish Human System Audit Short-Scale of Transformational Leadership
Published online by Cambridge University Press: 10 January 2013
Abstract
The aim of this research is to examine the psychometric properties of a Spanish version of the Human System Audit transformational leadership short-scale (HSA-TFL-ES). It is based on the concept of Bass developed in 1985. The HSA-TFL is a part of the wider Human System Audit frame. We analyzed the HSA-TFL-ES in five different samples with a total number of 1,718 workers at five sectors.
Exploratory Factor Analysis corroborated a single factor in all samples that accounted for 66% to 73% of variance. The internal consistency in all samples was good (α = .92 - .95). Evidence was found for the convergent validity of the HSA-TFL-ES and the Multifactor Leadership Questionnaire. These results suggested that the HSA-TFL short-scale is a psychometrically sound measure of this construct and can be used for a combined and first overall measurement.
El objetivo de esta investigación es examinar las propiedades psicométricas de la versión española de la escala corta de Liderazgo Transformacional de la Auditoría del Sistema Humano (HSA-TFL-ES). La escala se basa en el concepto de Liderazgo Transformacional desarrollado por Bass en 1985. La HSA-TFL-ES ha sido administrada a un total de 1,718 trabajadores, distribuidos en cinco muestras diferentes correspondientes a distintos sectores empresariales. El análisis factorial exploratorio corroboró la existencia de un solo factor que explica entre 66% y 73% de la varianza. La consistencia interna obtenida ha sido buena (α = .92 - .95). Además, los resultados obtenidos muestran validez convergente entre la escala HSA-TFL-ES y el Cuestionario Multifactorial de Liderazgo (Multifactorial Leadership Questionnaire - MLQ). Los resultados evidencian que la escala corta HSA es una medida psicométricamente adecuada del constructo de Liderazgo Transformacional, por lo que puede ser utilizada para una primera medición global del mismo.
