Child maltreatment and emotion socialization: Associations with executive function in the preschool years

Executive functioning in child victims of sexual abuse: A multi-informant comparative study

BACKGROUND

Research examining the association between child sexual abuse and executive functions is limited. Yet, exposure to traumatic situations at a young age has been associated with changes in the prefrontal cortex, which hosts executive functions (Wesarg et al., 2020). These functions are crucial for social adaptation, as they make it possible to inhibit maladaptive behavior and respond flexibly to the demands of the environment. As middle childhood is a sensitive period for the development of self-regulatory abilities, exploring executive functioning in school-age children could provide potential intervention targets (Dajani & Uddin, 2015).

OBJECTIVE

Using multiple informants, this study compared executive functioning of sexually abused children to that of non-sexually victimized children and examined whether the differences were moderated by sex.

METHODS

The sample consisted of 225, 6-to-12 years old children with a history of child sexual abuse (CSA) and 97 children without a history of CSA. Children completed two executive functioning tasks measuring cognitive flexibility and inhibition. Parents and teachers completed questionnaires evaluating children's executive functioning.

RESULTS

In comparison to non-abused children, children with a history of CSA displayed greater executive functioning difficulties as assessed by both informant-reported questionnaires and self-completed tasks. Significant interaction effects were found, such as CSA predicting lower inhibition and executive functions at school in boys but not in girls.

CONCLUSION

This study is a first step in understanding the association between CSA and executive functioning and offers a clearer picture of the differential impact of sexual trauma according to children's sex.

Early childhood trauma exposure and neurocognitive and emotional processes: Associations in young children in a partial hospital program

Early childhood trauma has been linked to neurocognitive and emotional processing deficits in older children, yet much less is known about these associations in young children. Early childhood is an important developmental period in which to examine relations between trauma and executive functioning/emotion reactivity, given that these capacities are rapidly developing and are potential transdiagnostic factors implicated in the development of psychopathology. This cross-sectional study examined associations between cumulative trauma, interpersonal trauma, and components of executive functioning, episodic memory, and emotion reactivity, conceptualized using the RDoC framework and assessed with observational and performance-based measures, in a sample of 90 children (ages 4-7) admitted to a partial hospital program. Children who had experienced two or more categories of trauma had lower scores in episodic memory, global cognition, and inhibitory control as measured in a relational (but not computerized) task, when compared to children with less or no trauma. Interpersonal trauma was similarly associated with global cognition and relational inhibitory control. Family contextual factors did not moderate associations. Findings support examining inhibitory control in both relationally significant and decontextualized paradigms in early childhood, and underscore the importance of investigating multiple neurocognitive and emotional processes simultaneously to identify potential targets for early intervention.

Longitudinal associations between child discipline methods and physical growth patterns across preschool years

OBJECTIVE

Research has documented the associations of child maltreatment with a range of physical health problems, but little is known about the physical growth patterns of children who experience maltreatment in early childhood. This study aimed to examine the association between various discipline approaches and physical growth in preschool-aged children.

METHODS

In the first year of preschool, parents of 661 Chinese preschool-aged children completed a questionnaire with items pertaining to the frequency of using physical maltreatment, psychological aggression, neglect, and nonviolent discipline toward the child. Children's weight and height were assessed annually using direct assessment in the first and two subsequent years. Longitudinal analyses were performed using multiple regression models.

RESULTS

More frequent neglect and psychological aggression during the first year of preschool were associated with a higher likelihood of a decreased BMI z score in subsequent years. Conversely, increased experience of physical maltreatment in the first year was associated with an increased likelihood of having overweight or obesity in the third year.

CONCLUSIONS

Results indicate that early maltreatment experience can impact physical growth. This highlights the importance of preventing abusive parenting and encouraging healthy habits in young children who have experienced maltreatment to decrease their future risk for weight problems.

The Protective Effects of Parent-Child Emotion Dialogues for Preschoolers Exposed to Intimate Partner Violence

Exposure to intimate partner violence (IPV) during early childhood is associated with self-regulation difficulties. Caregivers can facilitate children's self-regulation through emotion-focused conversations about past experiences, buffering downstream effects. However, caregivers experiencing violence may avoid distressing emotions activated by such conversations. This paper explores two different models of relational stress responses, one involving indirect effects (i.e. spillover effects) and the other moderation (i.e. buffering effects). Mothers (n = 117), oversampled for violence exposure, self-reported on IPV and participated in an emotional reminiscing task with children (aged 3-5 years); narratives were coded for maternal sensitive guidance. Maternal sensitive guidance was related to children's self-regulation. Sensitive guidance did not have indirect effects in the association between IPV exposure and children's self-regulation, but did buffer the association between physical IPV and self-regulation; this pattern did not hold for psychological IPV. Results suggest sensitive guidance during reminiscing may promote self-regulation in contexts of high IPV.

Academic Performance in Institutionalized and Noninstitutionalized Children: The Role of Cognitive Ability and Negative Lability

More research is needed to understand the factors that contribute to low academic achievement in institutionalized children. The aim of this study was to investigate the relationship between cognitive and emotion regulation skills and academic performance, by comparing institutionalized and noninstitutionalized Portuguese children. The sample comprised 94 participants (46 institutionalized (22 boys) and 48 noninstitutionalized (23 boys) children), aged between 6 and 10 years, matched for age and sex. We used Raven's Colored Progressive Matrices (RCPM) to measure cognitive abilities. Emotional regulation and negative lability were assessed using the Emotion Regulation Questionnaire (ERC). Academic performance was assessed with the Competence Academic Scale (CAS) of the Portuguese version of the Social Skills Rating System-Teacher Form (SSRS-T). Institutionalized children exhibited poorer academic performance than their noninstitutionalized counterparts (effect size, η2 = 0.174). Cognitive ability (β = 0.28) and negative lability (β = -0.28) were significant predictors of academic performance. In addition to institutionalization, cognitive ability, and the challenges of managing negative emotions may contribute to the observed differences in academic performance. Interventions aimed at fostering cognitive and emotional competencies may play a protective role for institutionalized children facing academic and social difficulties.

Methodological inconsistencies confound understanding of language measurement in the child maltreatment population: A systematic review

BACKGROUND

While researchers have found a link between childhood maltreatment and language difficulties, the underlying mechanisms remain unclear and replication across the literature is inconsistent.

OBJECTIVE

To conduct a systematic review examining the methodological inconsistencies related to studies' samples construction, maltreatment measurement, and language outcomes using a language acquisition theory-based approach.

METHODS

Using the PRISMA framework, a literature search was conducted across five databases to identify studies that have investigated the effects of maltreatment on the language dimensions of vocabulary and grammar. Data were extracted for participant and maltreatment characteristics.

RESULTS

Fifty articles were reviewed. The results revealed: 1) maltreated children performed consistently below peers on grammar but not vocabulary assessments, 2) disproportionate use of vocabulary assessments, 3) considerable variability on participant characteristics and limited multidimensional measurement of maltreatment exposure, and 4) only nine studies analyzed the relationship between a maltreatment dimension (e.g., type, severity) and language.

CONCLUSIONS

Based on the results of this review, we propose three calls to action: 1) more language acquisition research in the child maltreatment field, 2) specificity when constructing samples with maltreated children, and 3) comprehensive and multidimensional maltreatment measurement. Implications for education were examined.

Preschoolers' Intimate Partner Violence Exposure and Their Speeded Control Abilities Eight Years Later: A Longitudinal Mediation Analysis

Executive functioning (EF), or a set of related cognitive skills that facilitate goal-oriented behavior, is a critical aspect of adaptive development. Mounting research indicates that exposure to environmental threats during the preschool years jeopardizes EF; however, the extent and mechanisms through which early exposure to intimate partner violence (IPV) influences children's EF are unknown. Using data from an eight-year longitudinal investigation of mothers who had experienced IPV and their preschool-aged children (N = 120), this study examined the relative influence of recent and remote IPV exposure on speeded control-a component of EF influenced by processing speed-in late childhood. Results indicated that preschoolers' IPV exposure had a significant negative impact on their speeded control eight years later, and this relation was mediated by the remote effects of IPV on their mothers. Specifically, IPV was positively associated with maternal depression, which in turn contributed to greater use of negative parenting strategies when children were of preschool age. Children's IPV exposure during late childhood was not predictive of their concurrent speeded control. These findings lend further evidence to the notion that the preschool years are a sensitive period for the mastery of EF skills and that IPV exposure is a distinct risk factor that can have protracted effects on children's cognitive development. Further, this study points to modifiable environmental risk factors, which, through targeted prevention and intervention efforts, could promote EF across the lifespan.

The association between child maltreatment and sleep disturbances among preschoolers

BACKGROUND

Child maltreatment (CM) can result in lifelong detrimental consequences, but its association with sleep disturbances in young children remains unclear.

OBJECTIVE

This study aimed to investigate the association of CM with sleep disturbances and short sleep duration among Chinese preschoolers.

PARTICIPANTS AND SETTING

Data were from a representative sample of 17,023 children (6.17 ± 0.29 years old, 51.96% boys) at their graduation year of preschool in September 2019, as a subset of the Shanghai Children's Health, Education and Lifestyle Evaluation-Preschool (SCHEDULE-P) study.

METHODS

Parents reported children's CM of different types and the Children's Sleep Habits Questionnaire (CSHQ). Logistic regression was used to evaluate the risk of sleep disturbances and short sleep duration linked to CM.

RESULTS

Of the children, 12,583(73.92%) demonstrated sleep disturbances (CSHQ total score > 41) and 3017(17.72%) demonstrated short sleep duration (<9 h/night). After adjusting covariates, physical abuse (aOR = 1.16, 95%CI = 1.05-1.28) and emotional abuse (aOR = 1.50, 95% CI = 1.39-1.62) were associated with global sleep disturbances. Physical abuse (aOR = 1.16, 95% CI = 1.06-1.28), physical neglect (aOR = 1.29, 95%CI = 1.12-1.49), and emotional abuse (aOR = 1.19, 95% CI = 1.09-1.30) were associated with short sleep duration. Sexual abuse was not significantly associated with global sleep disturbances or short sleep duration. A cumulative association was noted that more CM types were associated with increased global sleep disturbances and short sleep duration.

CONCLUSIONS

CM is associated with sleep disturbances and short sleep duration in young children. This highlights the efforts to prevent and reduce CM in favor of optimal sleep and whole health in young children.

Associations of Early-Life Threat and Deprivation With Executive Functioning in Childhood and Adolescence: A Systematic Review and Meta-analysis

IMPORTANCE

Many studies have demonstrated an association between early-life adversity (ELA) and executive functioning in children and adolescents. However, the aggregate magnitude of this association is unknown in the context of threat and deprivation types of adversity and various executive functioning domains.

OBJECTIVE

To test the hypothesis that experiences of deprivation are more strongly associated with reduced executive functioning compared with experiences of threat during childhood and adolescence.

DATA SOURCES

Embase, ERIC, MEDLINE, and PsycInfo databases were searched from inception to December 31, 2020. Both forward and reverse snowball citation searches were performed to identify additional articles.

STUDY SELECTION

Articles were selected for inclusion if they (1) had a child and/or adolescent sample, (2) included measures of ELA, (3) measured executive functioning, (4) evaluated the association between adversity and executive functioning, (5) were published in a peer-reviewed journal, and (6) were published in the English language. No temporal or geographic limits were set. A 2-reviewer, blinded screening process was conducted.

DATA EXTRACTION AND SYNTHESIS

PRISMA guidelines were used to guide data extraction and article diagnostics (for heterogeneity, small study bias, and p-hacking). Article quality was assessed, and data extraction was performed by multiple independent observers. A 3-level meta-analytic model with a restricted maximum likelihood method was used. Moderator analyses were conducted to explore heterogeneity.

MAIN OUTCOMES AND MEASURES

Primary outcomes included measures of the 3 domains of executive functioning: cognitive flexibility, inhibitory control, and working memory.

RESULTS

A total of 91 articles were included, representing 82 unique cohorts and 31 188 unique individuals. Deprivation, compared with threat, was associated with significantly lower inhibitory control (F1,90 = 5.69; P = .02) and working memory (F1,54 = 5.78; P = .02). No significant difference was observed for cognitive flexibility (F1,36 = 2.38; P = .12). The pooled effect size of the association of inhibitory control with deprivation was stronger (Hedges g = -0.43; 95% CI, -0.57 to -0.29) compared with threat (Hedges g = -0.27; 95% CI, -0.46 to -0.08). The pooled effect size of the association of working memory with deprivation was stronger (Hedges g = -0.54; 95% CI, -0.75 to -0.33) compared with threat (Hedges g = -0.28; 95% CI, -0.51 to -0.05).

CONCLUSIONS AND RELEVANCE

Experiences of both threat and deprivation in childhood and adolescence were associated with reduced executive functioning, but the association was stronger for exposure to deprivation. Efforts to address the consequences of ELA for development should consider the associations between specific dimensions of adversity and specific developmental outcomes.

Profiles of Resilience among Children Exposed to Non-Maltreatment Adverse Childhood Experiences

Considering the high prevalence and negative consequences of non-maltreatment adverse childhood experiences (NM-ACEs), it is critical to understand their impacts on the resilient functioning of young children. This study sought to examine heterogeneity in resilience among first-grade children who were exposed to NM-ACEs during kindergarten and explore demographic and adversity characteristics that distinguish between resilience profiles. Latent profile analysis (LPA) was conducted on 4929 children drawn from the Early Childhood Longitudinal Study-Kindergarten (ECLS-K). The results of the LPA revealed four distinct resilience profiles: (1) low cognitive and executive functioning (4%); (2) low social and behavioral functioning (14%); (3) low average functioning (31%); and (4) multi-domain resilience (51%). Female children and those in families characterized by older maternal age, higher parental education level, household income above 200% federal poverty level, not receiving welfare benefits, and races other than Black were more likely to be in the multi-domain resilience profile. The findings highlight heterogeneity in resilience among children exposed to NM-ACEs and point to the need for a comprehensive, multi-domain assessment of child functioning to support optimal resilience development in this population.

Performance Differences Between Native and Non-Native Speakers on a New Happy-Sad Executive Function Measure

OBJECTIVE

The happy-sad task adapts the classic day-night task by incorporating two early acquired emotional concepts ("happy" and "sad") and demonstrates elevated inhibitory demands for native speakers. The task holds promise as a new executive function measure for assessing inhibitory control across the lifespan, but no studies have examined the influence of language of test administration on performance.

METHOD

Seventy adult native English speakers and 50 non-native speakers completed the computerized day-night and the new happy-sad tasks administered in English. In two conditions, participants were categorized pictorial stimuli either in a congruent manner ("happy" for a happy face) or in a more challenging, incongruent manner ("sad" for a happy face). Lexical decision performance was obtained to estimate levels of English language proficiency.

RESULTS

Native speakers and non-native speakers performed comparably except for the critical incongruent condition of the happy-sad task, where native speakers responded more slowly. A greater congruency effect for the happy-sad task was found for native than for non-native speakers. Lexical decision performance was associated with performance on the challenging incongruent conditions.

CONCLUSION

This study reinforced the usefulness of the happy-sad task as a new measure in evaluating inhibitory control in adult native-speakers. However, the language of test administration needs to be considered in assessment because it may lead to performance differences between native and non-native speakers.

Deprivation and threat as developmental mediators in the relation between early life socioeconomic status and executive functioning outcomes in early childhood

There has been a shift in the study of childhood adversity towards a focus on dimensions of adversity as opposed to a focus on cumulative risk or specific adversities. The Dimensional Model of Adversity and Psychopathology (DMAP) proposes deprivation and threat as core dimensions of childhood adversity. Previous work using DMAP has found links between deprivation and cognitive development and threat and emotional development in adolescence, but few studies have applied this framework to a poverty context, in which children are at heightened risk for adversity experiences, and none have examined outcomes in early childhood. We use data from the Family Life Project (n = 1292) to examine deprivation and threat at child age 24 months as developmental mediators in the association between socioeconomic status (SES) measured at 15 months and executive functions (EF) measured at 48 months. In a multiple mediation model, lower SES was related to higher deprivation and threat. Deprivation was negatively associated with EF, and threat was not associated with EF. Deprivation fully mediated association between SES and EF. These results expand previous work using the DMAP and point to new directions in understanding children’s cognitive adaptations to adversity.

The relationship of emotion regulation and negative lability with socioemotional adjustment in institutionalized and non-institutionalized children

With this study, we aimed to investigate the contribution of emotion regulation and negative lability to socioemotional adjustment in institutionalized and non-institutionalized children. Ninety-two children aged 6 to 10 years (45 placed in residential care after abuse and 47 non-abused, living with their biological families) participated in this study. Emotion Regulation Questionnaire and Strengths and Difficulties Questionnaire were completed by the main caregivers of the institutions and by the elementary teacher, respectively, for the institutionalized and non-institutionalized groups. No differences were observed between institutionalized and non-institutionalized children in emotion regulation, negative lability, and socioemotional adjustment outcomes. Also, no sex and age effects were observed for both groups. Considering the institutionalized children, the length of institutionalization had a significant effect on negative lability, while no effects of the type of maltreatment on emotion regulation and negative lability were observed. Additionally, in institutionalized children, negative lability was negatively associated with peer relationship problems in socioemotional adjustment, whereas in the non-institutionalized children, no significant associations were verified between emotion regulation and negative lability with socioemotional adjustment outcomes. For institutionalized children, emotional lability seems to have a differential impact on specific maladaptive socioemotional outcomes, which emphasizes the importance of analysing these specific risk developmental pathways.

Child diurnal cortisol differs based on profiles of maternal emotion socialization in high risk, low income, and racially diverse families

Young children's physiological and emotional regulation depend on supportive caregiving, especially in the context of stress and adversity. Experiences of child maltreatment become biologically embedded by shaping stress physiology. Maternal emotion socialization may have an important influence on children's limbic-hypothalamic-pituitary-adrenal (LHPA) functioning. Grounded in theories of caregiver emotion socialization, a person-centered latent profile analysis was utilized to identify profiles of maternal emotion socialization among a high risk, low income, and racially diverse group of 248 mothers and their young children (M_age  = 4.39 years, SD = 1.10). The majority of the mothers (n = 165) had a history of involvement with the Department of Child Services for substantiated cases of child maltreatment. A latent profile analysis was conducted revealing three emotion socialization profiles: disengaged, engaged, and engaged + supportive. Emotion socialization profile differences in children's diurnal cortisol levels and slope (using area under the curve with respect to ground and increase, respectively) were examined. Children's diurnal cortisol levels were higher, and slopes were flatter, when mothers used more disengaged emotion socialization strategies. Mothers who neglected their children were more likely to fit the disengaged profile than the engaged profile. Implications for the socialization of regulation in children exposed to adversity are discussed.

Examination of the associations between young children's trauma exposure, trauma-symptomatology, and executive function

The present study used a bioecological framework to examine associations between trauma exposure, trauma-related symptomatology, and executive function (EF) in an urban sample of 88 predominantly ethnic-minority, low-income preschoolers (age 2-5) exposed to interpersonal trauma. Contrary to hypotheses based on past literature documenting associations between trauma exposure and EF deficits in childhood, in regressions adjusting for child gender, family income, and caregiver education, neither trauma exposure or trauma-related symptoms (post-traumatic stress symptoms, internalizing behaviors, or externalizing behaviors) were significantly associated with children's EF performance. Associations between child trauma exposure, symptomatology, and executive function were not moderated by parental PTSD symptomatology; and EF was not differentially predicted by type of trauma. Results suggest that, within an ethnically-diverse sample of preschool-aged children exposed to multiple traumas, associations between trauma exposure, symptomatology, and EF may be particularly nuanced. Keywords: child trauma, posttraumatic stress, executive function, preschool-age children, child mental health.

Hair cortisol and dehydroepiandrosterone concentrations: Associations with executive function in early childhood

Chronic stress during childhood negatively impacts cognition and physical and mental health. Exposure to stressors over time can cause hypothalamic-pituitary-adrenal (HPA) axis dysregulation, leading to abnormal stress hormone levels, which can be reflected in hair cortisol concentration (HCC) and hair dehydroepiandrosterone (DHEA) concentration. Although the use of HCC and DHEA to measure chronic stress in children is increasing, their effects on cognition (as indexed by executive function) remain unexplored. Accordingly, we aimed to investigate the associations of HCC, DHEA, and their ratio with measures of executive function (cognitive flexibility and working memory) in a sample of kindergarten children (N=100). We found that the expected negative association between HCC and working memory approached significance, and DHEA was significantly and positively related to cognitive flexibility. We discuss possible interpretations of our findings. Our results suggest promising areas for future investigation and encourage further exploration into HCC and DHEA as measures of chronic stress.

Longitudinal associations between physically abusive parents' emotional expressiveness and children's self-regulation

The present study took a developmental psychopathology approach to examine the longitudinal association between parents' emotional expressiveness and children's self-regulation. Data collection spanned from 2004 to 2008. Ninety-two physically abusive parents completed yearly assessments of their emotional expressiveness, as well as their children's self-regulation abilities. Observational and behavioral measures were also obtained yearly to capture both parents' emotional expressiveness and children's self-regulation. Specifically, parents participated in a parent-child interaction task, which provided insight into their levels of flat affect. A puzzle box task was completed by each child to assess self-regulation. Results indicated, first, that greater parental expression of negative emotions predicted poorer self-regulation in children, both concurrently and across time. Second, parental expressions of positive emotions and parents' flat affect were unrelated to children's self-regulation. Findings inform our understanding of parental socialization of self-regulation and provide insight into the roles of distinct components of emotional expressiveness. Moreover, findings have crucial implications for understanding emotional expressiveness in high-risk samples and increase our understanding of within-group functioning among maltreating families that may serve as a means to direct intervention efforts.
