Inventory of Callous-Unemotional traits (ICU)
Callous traits have been assessed via parent-report using a validated questionnaire adapted from the Youth Self-Report and the Inventory for Callous-Unemotional Traits. At age 10 and 13, maternal reports were obtained using a brief validated questionnaire adapted from the Youth Self-Report and the Inventory for Callous-Unemotional Traits . The questionnaire comprises 7 items on interpersonal callous traits, which were scored on a 4-point Likert scale . To provide a more comprehensive measure of callous-unemotional traits, we expanded our measure at age 18 to include 17 items. 12 of the items are part of the Inventory of Callous-unemotional traits - Short form, which includes two subscales: callousness and uncaring. Items are scored on a 4-point Likert scale. The other 5 items are the remaining items used at age 10yrs from the Youth Self-Report.
