Are impairments in emotion recognition a core feature of callous–unemotional traits? Testing the primary versus secondary variants model in children
2018
The role of environmental adversity in the development of high callous–unemotional (CU)
traitsin children is controversial. Evidence speaks to the
traitsbeing largely independent of adversity; however, recent data shows that those with high CU
traitsand high adversity and/or high anxiety might differ in important ways from those with no such history. We tested this using
emotion recognition(ER) skills. We tested whether maltreatment history and anxiety levels moderated the relationship between level of CU
traitsand ER skills in N = 364 children with behavioral problems who were 3 to 16 years old. As hypothesised, in the full sample, the relationship between CU
traitsand ER differed according to maltreatment history, such that CU
traitswere associated with poorer recognition for those with zero or negligible history of maltreatment. This moderation of the CU-ER relationship by maltreatment was inconsistent across subgroups, however, and for the cohort utilizing youth self-report of maltreatment, high CU
traitswere associated with poor ER in those with lower anxiety levels. Maltreatment history and/or anxiety levels can identify different emotional impairments associated with high CU
traits, and the impairments might be characteristic of “primary” high CU
traitsdefined as occurring independently of maltreatment and/or high anxiety.
