Factor validation of the Portuguese version of the social skills scale of the preschool and kindergarten behavior scales

Abstract

The assessment of preschoolers' social skills represents a topic of growing importance in research recently developed in the field. The purpose of this article is to present confirmatory factor analyses studies for the Social Skills scale of the Preschool and Kindergarten Behavior Scales - Second Edition (PKBS-2), a behavior rating scale that evaluates social skills and problem behaviors, adapted and validated for Portuguese preschool children. The 34 items of the Social Skills scale, distributed on three subscales (Social Cooperation/Adjustment, Social Interaction/Empathy and Social Independence/Assertiveness), were grouped into item-parcels. Model adjustment was analyzed for the total sample (N = 2000) and the analyses were replicated for the subsamples collected in the home (n = 1000) and school settings (n = 1000). The factor structure was very stable for the three samples, with high internal consistency levels and correlations between parcels/scales. The results highlight the utility/validity of the Social Skills scale of the PKBS-2 (Portuguese version).
