Validación de la versión en español de las propiedades psicométricas de la escala Self-Report Habit Index (SRHI) para medir hábitos de ejercicio físico

Fundamentos: La medida de habitos de actividad fisica es especialmente importante en la evaluacion de las consecuencias de las enfermedades cronicas. Este estudio pretende validar la version espanola de la escala Self-Report Habit Index (SRHI), de 12 items, para medir la fuerza del habito. Metodo: Se analizaron sus propiedades psicometricas realizando un analisis estadistico de los items, un analisis factorial y una estimacion de la fiabilidad a traves del Alpha de Cronbach. Se utilizo una muestra de 222 alumnos universitarios de nuevo ingreso, de los que la mayoria ha practicado algun tipo de deporte durante su etapa escolar. Para evaluar la adecuacion de muestreo y la posible esfericidad de los datos obtenidos se aplicaron las pruebas de Kaiser-Meyer-Olkin (KMO) y Bartlett. Resultados: El coeficiente alfa de Cronbach fue 0,96. Los resultados de la extraccion de factores muestran la agrupacion de los 12 items en un unico factor con autovalor de 8,342 y un porcentaje de varianza total del 69,52%. Conclusiones: Los resultados demuestran que la escala es valida y fiable para medir habitos de actividad fisica. Se manifiesta una clara similitud de las propiedades psicometricas de la version espanola del SRHI con la version original.BACKGROUND The measurement of physical activity habits is especially important in the evaluation of the consequences of chronic diseases. The study tries was to validate to the context Spanish the scale Self-Report Habit Index (SRHI) of 12 items for to measure the habit strength. METHODS The psychometric properties of SRHI were analyzed realizing a analysis statistical of the items, an factorial analysis and an estimation of the reliability coefficient via Cronbach alpha. A sample of 222 university students of first year was used. The majority of they has practiced some type of sport during his school stage. To assess the adequacy of sampling and possible sphericity of data obtained, both Kaiser-Meyer-Olkin (KMO) tests were performed (which resulted in 0.953) and Bartlett (which resulted in p=.000). RESULTS The Cronbach alpha coefficient is 0.96. The results of a factor mining analysis (unrotated, orthogonal) point to a grouping of the 12 items into a single factor with eigenvalue of 8.342 and a percentage of total variance of 69.52%. CONCLUSIONS Results show that the scale is valid and reliable to measure physical activity habits A clear similarity of the psychometric properties of the Spanish version of the original version SRHI is shown.Psychometric Validation of the Spanish Version of the Scale Properties Self-Report Habit Index (SRHI) Measuring Physical Exercise Habits Background: The measurement of physical activity habits is especially important in the evaluation of the consequences of chronic diseases.
