Factorial Structure of the Parent-Reported Version of the Inventory of Callous-Unemotional Traits Among Belgian Children: A Theory-Based Model

Callous-Unemotional Traits and Co-occurring Anxiety in Preschool and School-age Children: Investigation of Associations with Family's Socioeconomic Status and Home Chaos

While contemporary literature has traditionally viewed youth with Callous-Unemotional (CU) traits as a homogeneous group, there is a growing interest in delineating two variants of CU traits based on high or low levels of anxiety. Extensive attention has been brought in the CU traits literature to the study of relational factors such as maltreatment and parenting practices. However, very few studies have looked at other environmental contexts in which the children within these two variants evolve, such as home chaos or socioeconomic status (SES). In a community sample of children aged 4 to 9, divided into a preschool sample (N = 107; Mage = 4.95, SD = 0.62) and a school-age sample (N = 153; Mage = 7.49, SD = 1.11), the current study investigated whether anxiety moderates the associations of CU traits with SES and home chaos. Hierarchical regression analyses revealed that CU traits were positively associated with home chaos, regardless of anxiety levels. CU traits were negatively associated with SES, but this effect emerged only at high levels of anxiety. Notably, these findings were observed solely in the school-age subsample. Implications for understanding the two variants of CU traits (i.e., primary and secondary) and hypotheses regarding their developmental trajectories are discussed.

Variants of Callous-unemotional traits in childhood: investigation of attachment profile and hostile attribution bias

There is increasing evidence of interest in describing two variants of CallousUnemotional (CU) traits based on high (secondary variant) or low (primary variant) levels of anxiety. However, studies are limited in childhood. The present study aimed to further the understanding of the variants, specifically in association with hostile attribution bias (HAB) and attachment. In a community sample of children aged 4 to 9 (N = 70), the study examined whether anxiety moderated the association of CU traits with HAB, secure and disorganized attachment representations. Hierarchical regression analyses revealed that CU traits were positively associated with disorganized attachment, regardless of the anxiety level. In contrast, CU traits were not associated with secure attachment. A significant interaction revealed that CU traits were positively associated with HAB only at high levels of anxiety. Implications for understanding the variants of CU traits and hypotheses regarding their developmental trajectories are discussed.

Primary and Secondary Variants of Callous-Unemotional Traits in Early and Middle Childhood: Distinction, Evaluation and Empathic Differences

Current literature demonstrates the relevance of considering two variants of CU traits based on high or low levels of anxiety. However, there is limited information about these variants in young community samples. The current study used cluster analyses to investigate the primary and the secondary variants of CU traits in two samples of children: preschool (N = 107; Mage = 4.95, SD = 0.62) and school-age (N = 153; Mage = 7.49, SD = 1.11). The identified clusters were compared on empathic dimensions, aggressive behavior and criteria from the "with limited prosocial emotions" specifier from the DSM-V. The primary variant was identified as early as preschool age while the secondary variant was only identified in the school-age sample. In this latter sample, the two variants did not differ on assessed variables, except for aggressive behavior. Despite the similarities between the two variants, these results suggest distinct developmental trajectories.

Conceptualizing Callous-Unemotional Traits in Chinese Preschoolers: Factor Structure and Measurement Invariance

With the increasing use of the Inventory of Callous Unemotional Traits (ICU) to examine callous-unemotional traits, few studies have explicitly tested the most appropriate ICU factor structures and measurement invariance in Chinese children at preschool age. This study was conducted with a large community sample of 2055 Chinese preschoolers (53.6% male, M age = 62.23 months, SD = 9.91) to test the most appropriate model of ICU and the measurement invariance across parent gender, child gender, as well as age. The confirmatory factor model suggested that the two-factor model with 11 items (ICU-11) is the best-fitting model for a Chinese preschool sample, which includes a callousness and an unemotional factor. The results from measurement invariance revealed that the factor structures were invariant across child gender, as well as child age and parental gender. The finding suggested that the ICU-11 may be a useful tool for evaluating CU traits in Chinese preschoolers.
