The Inventory of Callous-Unemotional Traits (ICU) is a copyright protected 24-item questionnaire designed to provide a comprehensive assessment of callous and unemotional traits. These traits have proven to be important for designating a distinct subgroup group of antisocial and aggressive youth. The ICU has three subscales: Callousness, Uncaring, and Unemotional. There are five versions of the scale: Youth Self-Report, Parent Report, Teacher Report, Parent Report (Preschool Version), and Teacher Report (Preschool Version). Researchers can download and use the ICU free of charge in their work. Copies of any publications using the ICU must be sent to firstname.lastname@example.org.
There is no manual for the ICU. For more information go to the developers webpage: here
the rating scale for items is on a 4-point Likert scale ranging from 0 (not at all true) to 3 (definitely true). There are twelve reverse scored items (items 1, 3, 5, 8, 13, 14, 15, 16, 17, 19, 23, 24). The three sub-scales and their items are listed below:
Callousness 4, 8, 9, 18, 11, 21, 7, 20, 2, 10, 12
Uncaring 15, 23, 16, 3, 17, 24, 13, 5.
