Confirmatory Factor Analyses of Self- and Parent- Report Inventory of Callous-Unemotional Traits in 8- to 10-Year-Olds

The factorial structure of the Inventory of Callous-Unemotional Traits (ICU; Frick 2004) has been inconsistent across various studies using different rater versions and samples. In this study the factorial structure of the self- and parent-report versions of the ICU was examined in a community sample of 340 boys and girls aged 8- to 10- years. A series of confirmatory factor analyses revealed that (1) for self-report ICU, a two-factor model comprising one Uncaring and one Callousness factor fit the data best; the factorial structure was invariant across sex, although boys showed higher scores than girls on the Uncaring factor; (2) for the parent-report ICU, a three-factor structure was supported, and boys and girls did not differ on factor structure or levels of the factors. For both versions, CU traits were positively associated with the count of Oppositional Defiant Disorder/Conduct Disorder and internalizing behavior symptoms, demonstrating ICU’s good convergent albeit unsatisfactory discriminant validity. Findings suggest further refinement of this instrument for the self-report and parent versions separately.
