Resumen


Abstract

Although the Decisional Balance Scale (DBS) for exercise has been established to have sound psychometric properties, the factorial structure of this instrument has not been examined in other  European countries. The purpose of this study was to test a short version of the decisional balance scale for exercise in Greek adults. The DBS was administered to 158 (61.2%) women and 100 (38.8%) men. An exploratory factor analysis yielded a positive (pros) factor and a negative (cons) factor. The results from confirmatory factor analysis indicated that the two-factor structure was the best fit for the DBS when it was used with Greek adults. The alpha coefficients were .84 for the positive factor and .81 for the negative factor. The findings are similar to those of the English original, and suggest that the revised DBS can be used in exercise and activity research with Greek adults. However, to expand the usefulness of this instrument across cultures, the DBS should continue to be tested with other Greek populations and settings.

Resumen

La escala del equilibrio decisional (DBS) presenta unas sólidas propiedades psicométricas, no obstante la estructura factorial de dicho instrumento no se ha examinado en otros países europeos. Este estudio tiene como objetivo probar una versión corta de la escala decisional sobre ejercicio a una muestra de adultos griegos. La DBS revisada se administró a 158 (61.2%) participantes mujeres y 100 (38.8%) hombres. El análisis factorial exploratorio mostró la presencia de dos factores, uno positivo (los pros) y uno negativo (los contras). Los resultados del análisis factorial confirmatorio indicaron que la mejor solución factorial para la versión griega de la escala DBS se componía de una doble estructura. Los coeficientes alpha fueron de .84 para el factor positivo y de .81 para el factor negativo. Los hallazgos de este estudio fueron similares a los de la versión original, indicando que la revisada DBS es adecuada para utilizarse en investigaciones sobre la actividad física y el ejercicio con participantes griegos adultos. No obstante para poder extender el uso de este instrumento en diferentes culturas, la DBS debería continuar a ser probada a diferentes poblaciones griegas y distintos contextos.
