| Abstract: | The main aim of the study was to determine the psychometric properties of the version of the Early Childhood Behavior Questionnaire (ECBQ) adapted to Polish culture. Since temperament in toddlers was being observed in a laboratory, an external validity of the ECBQ was also provided. Kagan’s observational paradigm was used to test 215 18-month-old children. Their parents completed the ECBQ twice, when the children were 26 and 30 months old. The results showed good internal consistency and confirmed the longitudinal stability of the scale. The same three-factor solution was found in the structure of the scale as in the original American study. The convergence between the observational and parent report data supported the ECBQ’s external validity. Similarities in the structure of the scale observed between the Polish and American data are discussed from a cross-cultural perspective. The usefulness of the Polish ECBQ and the limitations of the obtained results are discussed. |
