This study aimed to verify the psychometric qualities of the Preschool and Kindergarten Behavior Scale (PKBS) for the Brazilian context. Subjects were parents and teachers of 143 children, between three and six years old, from two inner cities of the São Paulo (Brazil). The PKBS-BR has two forms, one for social skills and another for behavior problems. Parents and teachers individually completed the PKBS-BR. Factor analysis indicated a three factor structure for the social skills scale (Social Cooperation, Social Independence and Social Interaction) and two factors for the behavior problems scale (Externalizing and Internalizing problems). The factors explained, respectively, 45.38% and 42.12% of the data variance. The internal consistency measures were satisfactory, varying between 0.79 and 0.95. Some similarities and differences between American and Brazilian versions and the PKBS utility for research and psychological intervention are discussed.
