Child maltreatment increases the risk for callous-unemotional traits: A three-level meta-analytic review

Callous-unemotional (CU) traits are characterized by lack of remorse and guilt, lack of empathy, and shallow and deficient emotions. A growing body of research has examined the association between child maltreatment and CU traits. However, empirical findings on this association are inconclusive. Therefore, this meta-analytic review aimed to examine the overall association between child maltreatment and CU traits and potentially moderating variables. After searching five databases (Web of Science, ScienceDirect, PubMed, MEDLINE, and CNKI), a total of 37 studies (N = 26,010 participants) yielding 165 effect sizes were synthesized in three-level meta-analytic models. Results showed that child maltreatment is significantly and positively related to CU traits (mean r = .183; p < .001). Moderator analyses showed that this association is larger in females than in males, larger in community samples (r = .243) than in clinical samples (r = .073), and in terms of CU trait dimensions stronger for callousness (r = .251) than for uncaring (r = .134) and unemotional dimensions (r = .050). It is concluded that child maltreatment is a risk factor for the development of CU traits and discussed that interventions for CU traits in antisocial groups should be aware of the environmental influence of interpersonal trauma resulting from childhood maltreatment experiences.
