Estructura factorial de la Escala de Balance Afectivo en población normativa

This study analyses the dimensionality and psychometric properties of the Affective Balance Scale by comparing two versions, the original by Warr, Barter, and Brownbridge (1983) and the proposed by Godoy-Izquierdo, Martínez, and Godoy (2008), and examines the effect of some items’ wording on the possible outcome. Six-hundred people between the ages of 18 and 58 from the normative population participated in the study. Even though the two versions of the scale present an acceptable and similar goodness of fit index (GFI), the proposed version demonstrated greater reliability and better mean discrimination. The research also found a good adjustment for the second order factor structure (affective balance) with two first order factors (negative and positive affect). Even though the findings only indicated an effect on the items with a positive affect dimension, it is our recommendation that users of the scale adopt the proposed version and refrain from using ‘very’ as item qualifier.
