Callous and unemotional traits

Callous-unemotional traits (CU) are distinguished by a persistent pattern of behavior that reflects a disregard for others, and also a lack of empathy and generally deficient affect. The interplay between genetic and environmental risk factors may play a role in the expression of these traits as a conduct disorder (CD). While originally conceived as a means of measuring the affective features of psychopathy in children, measures of CU have been validated in university samples and adults. A CU specifier has been included as a feature of conduct disorder in the fifth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and the eleventh edition of the International Classification of Diseases (ICD-11). CU traits, as measured by the Inventory of Callous-Unemotional Traits (ICU), are in three categories: callous (reflecting ruthlessness and cruel treatment or disregard for others), uncaring (passive disregard for others and lack of prosocial emotion), and unemotional (limited experience and expression of emotion). Unemotional traits are uniquely elevated in cases reflecting "primary psychopathy". DSM-5's "limited prosocial emotions" specifier and attendant interview measure, the Clinical Assessment of Prosocial Emotions (CAPE), lists the following characteristics: Lack of remorse or guilt Shallow or deficient affect (unemotionality) Callous–lack of empathy Unconcerned with performance (at work or school) Lack of reaction to what would be a traumatic event Children with CU traits have distinct problems in emotional and behavioral regulation that distinguish them from other antisocial youth and show more similarity to characteristics found in adult psychopathy. Antisocial youth with CU traits tend to have a range of distinctive cognitive characteristics. They are often less sensitive to punishment cues, particularly when they are already keen for a reward. CU traits are positively related to good intellectual verbal skills. A CU specifier for conduct disorder was added to DSM-5.
