Social skills deficits and some behavior problems are a well-established issue in preschoolers with autism spectrum disorder (ASD). However, most of the studies available analyze social skills or behavior problems of children with ASD, but not both. The present study intends to compare the social skills and behavior problems of 32 preschoolers with ASD paired with 32 typically developing preschoolers, as evidence of validity of the Portuguese version of the Preschool and Kindergarten Behavior Scales – Second Edition (PKBS-2). Each child was rated independently by parents and teachers. Results showed a statistically significant difference in all PKBS-2 scores between the two groups, with the children with ASD rated with fewer social skills and more behavior problems by both informants. The discriminant analysis highlighted the three Social Skills, the Over-Activity/Lack of Attention and Social Withdrawal subscales as more accurate in differentiating between the two groups. The implications of using a single behavior rating scale that can be filled in by different informants (parents and teachers) to assess positive and negative behaviors are emphasized. Furthermore, the usefulness of the PKBS-2 as a screening assessment tool that could be used in clinical practice and intervention with preschoolers with ASD is discussed.
