Psychometric Properties of Two Short Versions of the Inventory of Callous–Unemotional Traits Among Incarcerated Youth [2018]

Accumulating evidence shows callous–unemotional (CU) traits to delineate a subgroup of youth with unique etiological underpinnings to their conduct problems. Due to its inclusion as a conduct disorder specifier in Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5), research that evaluates the psychometric properties of measures used to assess this construct is essential. The present study contributes to this area of investigation by examining two recently developed brief versions (10- and 12-item) of the Inventory of Callous–Unemotional Traits (ICU) among a Portuguese sample of incarcerated male juvenile offenders (N = 221). Each of these shortened versions demonstrated evidence in terms of factor structure, internal consistency, and convergent/discriminant validity with theoretically meaningful constructs. In line with prior research, there was evidence of unique correlations between separate ICU subscales and several outcomes of interest. Study findings indicate that the two shortened versions of the ICU, and particularly the ICU-12, may offer researchers and clinicians a relatively brief and psychometrically sound means of assessing CU traits.
