The Inventory of Callous Unemotional Traits: A reliability generalization meta-analysis.

The Inventory of Callous Unemotional Traits (ICU) is the most commonly used measure of Callous Unemotional (CU) traits. However, its internal consistency reliability estimates vary substantially across different studies. This article reports findings from a reliability generalization (RG) meta-analysis, which included 146 studies (N = 64,356), to estimate the overall Cronbach's alpha values of ICU scores. Mixed-effects moderator analyses were...
