Psychometric properties of the Portuguese teacher-version of the Inventory of Callous-Unemotional Traits.

Callous unemotional (CU) traits refer to specific deficits in affective experience and interpersonal style, characterized by absence of guilt, constrictive display of emotion and failure to show empathy, callous use of others for one's own gain. The Inventory of Callous-Unemotional Traits (ICU) was developed to measure CU traits in children and adolescents. The aim of this study was to analyze the factorial structure of the Portuguese version of teacher-report ICU for children in school age and examine psychometric properties such as internal consistency and convergent validity in a community sample. Thirty-six teachers provided behavioral ratings of 100 and 78 children of elementary school, 88 boys and 90 girls, aged between 6 and 10 years old. Confirmatory factor analyses provided further support to a 2-factor structure, comprising the following dimensions: callous and uncaring. This study showed that the ICU seems a reliable an accessible tool that can be used in the Portuguese educational context to evaluate CU traits with low time consumption.
