This cross-sectional study established the psychometric properties and factor structure of the Preschool and Kindergarten Behavior Scales (PKBS) and an index of empathy in a sample of Swedish four to six year olds (N = 115). Using Bayesian structural equation modeling, we found that a five-factor PKBS and one-factor empathy model provided good fit to the data, posterior predictive p-value (PPP) = 0.246. Results indicated good internal consistency ([omega] 0.73 to 0.92). Consistent with the CASEL model and prior research, positive associations were found between social emotional competencies. Relationship skills were positively associated with empathy and negatively associated with internalizing problems. Results provided support for the use of the PKBS as well as the empathy scale in Swedish preschools.
