Longitudinal Associations between Callous-unemotional (CU) Traits and School-based Affiliative Relationships among South Korean Children

Objective Linguistic Markers Associated with Callous-Unemotional Traits in Early Childhood

BACKGROUND

Callous-unemotional (CU) traits are associated with interpersonal difficulties and risk for severe conduct problems (CP). The ability to communicate thoughts and feelings is critical to social success, with language a promising treatment target. However, no prior studies have examined objective linguistic correlates of childhood CU traits in early childhood, which could give insight into underlying risk mechanisms and novel target treatments.

METHODS

We computed lexical (positive emotion, sad, and anger words) and conversational (interruptions and speech rate) markers produced by 131 children aged 5-6 years (M = 5.98; SD = 0.54, 58.8% female) and their parents while narrating wordless storybooks during two online visits separated by 6-8 weeks (M = 6.56, SD = 1.11; two books, order counterbalanced). Audio recordings were diarized, time-aligned, and orthographically transcribed using WebTrans. Conversational markers were calculated using R and word frequencies were calculated using Linguistic Inquiry and Word Count (LIWC) software. We examined links between child CU traits and linguistic markers, and explored whether relationships were moderated by child sex.

RESULTS

Higher CU traits were associated with fewer positive emotion words produced by parents and children. Higher CU traits were also associated with greater concordance in the degree of interruptions and expression of anger emotion words by parents and children.

CONCLUSIONS

Results suggest that objective linguistic correlates of CU traits are detectable during early childhood, which could inform adjunctive treatment modules that improve outcomes by precisely tracking and targeting subtle communication patterns.

Peer Victimization and Callous-Unemotional Traits: The Impact of Parents and Teachers

Research on the link between peer victimization and callous-unemotional (CU) traits has primarily relied on cross-sectional designs and yielded equivocal findings. In light of the poor outcomes related to peer victimization and CU traits, it is important to determine whether this link is reciprocal in nature and to identify factors that may influence its strength. Accordingly, the current study investigated the bidirectional association between peer victimization and CU traits over a 6-month period, accounting for the moderating effects of parents (i.e., support and hostility) and teachers (i.e., support and conflict). Participants included 284 third- through fifth-grade students (ages 7-12; 51.8% boys; 51.1% Hispanic) and their homeroom teachers. Children provided ratings of peer victimization, parental hostility, and parent and teacher support. Teachers provided ratings of CU traits and student-teacher conflict. A series of cross-lagged panel models were estimated. Results revealed that, at higher levels of parental hostility, peer victimization predicted increases in CU traits over time; in contrast, peer victimization predicted decreases in CU traits at lower levels of parental hostility. Surprisingly, at higher levels of teacher conflict, peer victimization predicted decreases in CU traits over time. CU traits did not interact with parent or teacher variables to predict subsequent peer victimization. Moreover, parental hostility was positively associated with subsequent peer victimization, whereas teacher support predicted decreases in victimization over time. These findings build on previous research examining environmental influences on the expression of CU traits by highlighting peer victimization and parental hostility as potential risk factors.

Callous-unemotional Traits and Child Response to Teacher Rewards, Discipline, and Instructional Methods in Chinese Preschools: A Classroom Observation Study

Atypical responses to teacher rewards, discipline and different forms of instructional methods have been identified as potential contributors to disruptive behavior, low school engagement, and academic underachievement in children with elevated callous-unemotional (CU) traits. To date, research on CU traits in schools has relied on interview or questionnaire methods and has predominantly been conducted in Western countries. Thus, the present study aims to investigate the relationships between CU traits and children's responses to teacher rewards, discipline and instructional methods in the Chinese preschool context using classroom observation. Eight teachers (7 females, 1 male; M = 37.66 years) and 116 children (56% girls; M = 5.16 years) from two mainstream Chinese preschools participated in the study. Of the 116 eligible children, the behavior of 108 children from four classes were observed during classroom activities. Findings indicated that CU traits were not related to children's responses to discipline, nor did CU traits moderate the relationship between instructional methods and children's academic engagement. Higher CU traits predicted a greater frequency of one-to-one teacher-child interaction. Our findings offer initial insights into the potential of early school-based interventions in fostering engagement and prosocial behavior among children with CU traits. However, they also highlight the need for additional support for preschool teachers, who face the challenge of managing these high-risk children who appear to require more individual time and attention.

Callous-unemotional traits and externalizing problem behaviors in left-behind preschool children: the role of emotional lability/negativity and positive teacher-child relationship

BACKGROUND

Callous-unemotional traits and emotional lability/negativity of young children have been regarded as the markers of externalizing problem behaviors. Based on the sensitivity to threat and affiliative reward model and the general aggression model, emotional lability/negativity may act as a mediator in the relationship between callous-unemotional traits and externalizing problem behaviors. Additionally, a positive teacher-child relationship could act as a buffer given the parental absence in left-behind children. However, these links remain unexplored in left-behind preschool children. Therefore, this study explored the link between callous-unemotional traits of left-behind preschool children and externalizing problem behaviors, as well as the mediating role of emotional lability/negativity and the moderating role of a positive teacher-child relationship.

METHOD

Data were collected on 525 left-behind children aged 3 to 6 years from rural kindergartens in China. Preschool teachers reported all data through an online survey platform. Moderated mediation analysis was performed to examine whether the mediated relation between callous-unemotional traits and externalizing problem behaviors was moderated by a positive teacher-child relationship.

RESULTS

The results showed callous-unemotional traits significantly predicted externalizing problem behaviors and lability/negativity acted as a mediator, while a positive teacher-child relationship acted as a protective factor in moderating the relationship between callous-unemotional traits and emotional lability/negativity. This study identified a moderated mediation effect among the four variables in left-behind preschool children in China.

CONCLUSION

The findings provide support for the advancement of theoretical foundations, and provide an avenue for further exploration to support the mental health and overall development of left-behind children during early childhood.

Callous-Unemotional Traits and Social Adjustment among Chinese Preschoolers: The Moderating Role of Teacher-Child Relationship

Callous-unemotional (CU) traits are associated with social adjustment difficulties, but few studies have examined the underlying mechanisms in Chinese preschoolers. This study examined the relationship between CU traits and social adjustment among Chinese preschoolers as well as the moderating role of the teacher-child relationship in the association. Participants were 484 preschool children aged 3-6 years old from Shanghai, China (Mage = 5.56 years, SD = 0.96 years). Parents reported children's CU traits and teachers reported their relationship with children and rated children's social adjustment as well. The results revealed that (1) children with higher CU traits positively related to aggressive and asocial behavior with peers, but negatively related to prosocial behavior; (2) the teacher-child relationship moderated the relationship between CU traits and social adjustment in children. Specifically, teacher-child conflict exacerbated the aggressive and asocial behavior of children with CU traits and reduced the prosocial behavior of children with CU traits. These findings extended the current research on CU traits and had important implications for early interventions targeted at children with CU traits.

The Influence of Antisocial Behavior and Callous-Unemotional Traits on Trajectories of School Engagement and Achievement in South-Korean Children

Poor educational outcomes are common among children with antisocial behavior problems, including among a subgroup of antisocial children with callous-unemotional traits, who show deficits in empathy, guilt, and prosociality. However, few studies have explored the unique contributions of antisocial behavior and callous-unemotional traits to school outcomes and most prior studies have been conducted in Western countries. The current study thus tested associations between callous-unemotional traits, antisocial behavior, and trajectories of school outcomes among South Korean children. Participants aged 10-12 years (N = 218; 52% boys) completed questionnaires assessing antisocial behavior, callous-unemotional traits, verbal ability, and school engagement, and teachers provided children's Math and Korean grades at three time points during a single academic year. Prospective associations were explored in conditional latent growth curve models. Both antisocial behavior and callous-unemotional traits were related to lower school engagement at the start of the academic year, but the magnitude of the associations was greater for callous-unemotional traits, suggesting a greater adverse effect of callous-unemotional traits on engagement than antisocial behavior. Moreover, children with high levels of callous-unemotional traits showed stable and low levels of school engagement. There were no significant predictive associations between antisocial behavior or callous-unemotional traits and trajectories of academic grades. The findings suggest that interventions aimed at improving educational outcomes among antisocial children should be tailored according to the presence of callous-unemotional traits to target the specific needs of individual students, particularly at the start of the school year.
