The Effect of CRHBP rs10062367 Polymorphism and Parenting Styles on Internalizing Problems in Preschoolers: The Moderating Effect of Sensory Processing Sensitivity

The present study aimed to examine how CRHBP rs10062367 polymorphism interacted with parenting styles and sensory processing sensitivity (SPS) to impact on preschoolers' internalizing problems. A total of 446 preschoolers (Mage = 4.55, SD = 1.07) participated in the study and their saliva were extracted to genotype the CRHBP rs10062367 polymorphism, and their parents were invited to complete a battery of questionnaires to assess parenting styles, preschoolers' SPS, and internalizing problems. Results indicated that high SPS preschoolers with A allele exhibited fewer internalizing problems under the condition of positive parenting while they exhibited more internalizing problems under the condition of negative parenting. The findings provide support for the Differential Susceptibility Model/Biological Sensitivity to Context Theory that A allele of rs10062367 and high SPS might be the "susceptibility markers" of children to environments.

A four-year longitudinal analysis examining the effects of e-cigarette advertisements and disparities among youth with internalizing problems

BACKGROUND

Prior research indicates a direct, short-term effect of e-cigarette advertising on e-cigarette use among youth. This study seeks to investigate the long-term effects of e-cigarette advertisements and disparities in exposure among adolescents with different levels of internalizing problems.

METHODS

Panel data of the Population Assessment of Tobacco and Health (PATH) Study Waves 3-5 (2015-2019) were analyzed. Youth aged 12-17 who were non-e-cigarette users at the time of Wave 3 were included (n = 4,678). A moderated mediation model was employed to examine the mediating role of perceived harm of e-cigarettes and the moderating effect of internalizing problems.

RESULTS

Exposure to e-cigarette advertisements in Wave 3 predicted lower harm perception of e-cigarette in Wave 4 (bp = -0.055, p <.01), leading to more e-cigarette use in Wave 5 (bp = -0.042, p <.001). While e-cigarette advertisements exhibited a lasting indirect effect (bp = 0.002, p <.05), there was no long-term direct effect (bp = 0.017, p >.05) on youth e-cigarette use. Furthermore, a moderating effect of internalizing problems was observed (bp = 0.107, p <.05).

CONCLUSIONS

E-cigarette advertisements can exert a lasting influence indirectly by diminishing harm perception, particularly among those with lower internalizing problems. Adolescents with higher internalizing problems exhibit lower susceptibility to advertisement influence, yet their perceived harm of e-cigarettes is notably lower than their peers with fewer internalizing problems. These disparities underscore the need for tailored prevention strategies: implementing anti-e-cigarette education programs for adolescents with low internalizing problems and providing mental health care for those facing internalizing challenges. Regulatory measures targeting e-cigarette advertising are also crucial.

Parent-child educational aspiration congruence and adolescents' internalizing problems: The moderating effect of SES

Previous studies have found that adolescents and their parents may hold discrepant views about educational aspirations. However, little is known about how these discrepancies affect adolescents' internalizing problems and the moderating effect of SES on the relation between (in)congruence of parent-child educational aspirations and adolescents' internalizing problems. Therefore, this study explored the relation between (in)congruence of parent-child educational aspirations and adolescents' internalizing problems, and further tested the moderating role of SES. Based on two-wave survey data collected from a nationally representative sample of 8194 parent-child dyads in China (51.3 % boys, mean age = 13.58 years), multilevel polynomial regression and response surface analysis were performed to investigate the hypotheses. The results found that (1) internalizing problems were minimal when the two educational aspiration variables were congruent, (2) internalizing problems were the highest when the discrepancy between child educational and parental educational aspirations was largest, and (3) SES moderated the relation between (in)congruence in educational aspirations and adolescents' internalizing problems. The study's results not only comprehensively and intuitively reveal the influence of parents' and children's educational aspirations on adolescents' internalizing problems, but also provide targeted guidance and suggestions regarding parenting practices for families from diverse SES backgrounds.

The relationship between childhood maltreatment subtypes and adolescent internalizing problems: The mediating role of maladaptive cognitive emotion regulation strategies

BACKGROUND

While childhood maltreatment is understood to be a significant risk factor for adolescent internalizing problems (depression and anxiety), underlying mechanisms linking each type of maltreatment to internalizing problems in adolescents remain unclear. Moreover, the current state of knowledge regarding the associations between maladaptive cognitive emotion regulation strategies and each type of maltreatment, as well as their impact on adolescent internalizing problems, is limited. Additionally, it remains unclear whether these maladaptive strategies mediate this relationship.

OBJECTIVE

This study sought to investigate the effects of childhood maltreatment types on adolescent internalizing problems and to explore whether the overall and specific types of maladaptive strategies mediate these associations.

METHODS

Using a cross-sectional design, adolescents (N = 7071, Mage = 14.05 years, SDage = 1.54) completed online questionnaires assessing childhood maltreatment, maladaptive cognitive emotion regulation strategies (including rumination, catastrophizing, self-blame, and other-blame), anxiety, and depression. The hypothesized mediating effects were tested using the Lavaan package in R software (4.1.2).

RESULTS

Different maltreatment types had varying effects on adolescent internalizing problems. Emotional neglect, emotional abuse, and sexual abuse significantly affected anxiety and depression, whereas physical neglect and physical abuse did not. Other than physical neglect and physical abuse, overall maladaptive strategies mediated the relationship between the other three types of maltreatment (emotional abuse, emotional neglect, and sexual abuse) and internalizing problems (anxiety and depression). For specific maladaptive strategies, rumination mediated the effects of physical abuse, emotional abuse, emotional neglect, and sexual abuse on internalizing problems (anxiety and depression). In contrast, catastrophizing mediated the relationship between physical neglect, emotional abuse, emotional neglect, sexual abuse and internalizing problems (anxiety and depression).

CONCLUSIONS

These results suggest that the effects of maltreatment types on internalizing problems are different and that maladaptive strategies, particularly rumination and catastrophizing, are important mechanisms through which childhood maltreatment affects internalizing problems. This is a reminder that mental health workers need to consider the different effects of maltreatment types when intervening and recognize the importance of prioritizing interventions for rumination and catastrophizing.

The role of parental stress on emotional and behavioral problems in offspring: a systematic review with meta-analysis

OBJECTIVE

Empirical evidence underscores an association between parental stress and emotional and behavioral problems in offspring. However, a comprehensive systematic review or meta-analysis on this topic is lacking. Thus, this study aims to address the scientific inquiry: Is there a relationship between parental stress and emotional/behavioral problems in children?

SOURCES

This systematic review with a meta-analysis surveyed PubMed, PsycINFO, and the Biblioteca Virtual em Saúde between August and September 2021. The present search combined terms (school-age children) AND (parental stress OR parenting stress OR family stress) AND (emotional and behavioral problems OR internalizing and externalizing problems). Eligibility criteria encompassed cross-sectional, cohort, and case-control studies published within the last five years, exploring the association between parental stress (stressful life events and parenthood-related stress disorders) and emotional/behavioral problems in school-age children. PROSPERO ID CRD42022274034.

SUMMARY OF THE FINDINGS

Of the 24 studies meeting all inclusion criteria (n = 31,183) for the systematic review, nine were eligible for inclusion in the meta-analysis. The meta-analysis revealed an association between parental stress and emotional problems (COR: 0.46 [95 % CI: 0.27 - 0.61], p < 0.001, Heterogeneity = 89 %) as well as behavioral problems (COR: 0.37 [95 % CI: 0.27 - 0.46], p < 0.001, Heterogeneity = 76 %).

CONCLUSIONS

These findings indicate that parental stress predicts emotional/behavioral problems in school-age children. Since these problems are related to long-term negative effects in adulthood, these results are crucial for preventing mental health problems in offspring and for screening and managing parental stress.

High screen time and internalizing and externalizing behaviours among children aged 3 to 14 years during the COVID-19 pandemic in France

Children's screen time increased as a result of the COVID-19 pandemic. In the summer of 2021, we explored the association between high screen time over a period of one year since May 2020 and behavioural problems among children and adolescents. The data were derived from the French EpiCov cohort study, collected in spring 2020, autumn 2020, and spring 2021. Participants (N = 1089) responded to online or telephone interviews about one of their children aged 3 to 14 years. Screen time was categorized as high if the daily mean screen time exceeded recommendations at each collection time. The Strengths and Difficulties Questionnaire (SDQ) was completed by parents to identify internalizing (emotional or peer problems) and externalizing (conduct problems or hyperactivity/inattention) behaviours in their children. Among the 1,089 children, 561 (51.5%) were girls, the average age was 8.6 years (SD 3.7). Internalizing behaviours: High screen time was not associated with internalizing behaviours (OR [95% CI] 1.20 [0.90-1.59]) or emotional symptoms (1.00 [0.71-1.41]) while it was associated with peer problems (1.42 [1.04-1.95]). Externalizing behaviours: High screen time was associated with externalizing problems (1.63 [1.01-2.63]) and conduct problems (1.91 [1.15-3.22]) only among older children aged 11 to 14 years. No association with hyperactivity/inattention was found. In a French cohort, exploration of persistent high screen time in the first year of the pandemic and behaviour difficulties in Summer 2021 resulted in mixed findings according to behaviour's type and children's age. These mixed findings warrant further investigation into screen type and leisure/school screen use to enhance future pandemic responses appropriate for children.

Internalizing problems in individuals with reading, mathematics and unspecified learning difficulties: a systematic review and meta-analysis

We conducted a systematic review and meta-analysis to examine if individuals with reading difficulties (RD), mathematics difficulties (MD), or unspecified learning difficulties (ULD) experience internalizing problems (i.e., anxiety, depression, somatic complaints, and social withdrawal) to the same extent, and if the effect sizes are influenced by moderators (age, internalizing problems type, anxiety type, rater type, selection criteria, and attention control). We reviewed 2,806 studies published in English between January 2000 and April 2023. Our final sample consisted of 96 studies that reported effect sizes or data to calculate them (a total of 120 unique samples, 83,260 participants, age range = 7.3 - 34.8 years). Risk of bias and sensitivity were assessed. A random-effects model analysis revealed a significant and moderate overall effect size (Hedge's g = -.54), indicating that individuals with RD, MD or ULD experience more internalizing problems than their chronological-age (CA) controls. Follow-up analyses showed that neither learning difficulties type nor age of participants were significant moderators, but selection criteria (diagnosis versus screening) and internalizing problems type were. These findings suggest that individuals with RD do not differ from those with MD or ULD in internalizing problems, and all fare poorly compared to CA controls.

Multiple Risk in Pregnancy- Prenatal Risk Constellations and Mother-Infant Interactions, Parenting Stress, and Child Externalizing and Internalizing Behaviors: A Prospective Longitudinal Cohort Study from Pregnancy to 18 Months Postpartum

Multiple risk is associated with adverse developmental outcomes across domains. However, as risk factors tend to cluster, it is important to investigate formation of risk constellations, and how they relate to child and parental outcomes. By means of latent class analysis patterns of prenatal risk factors were identified, and relations to interactional quality, parenting stress, and child internalizing and externalizing behaviors were investigated. An array of prenatal risk factors was assessed in 1036 Norwegian pregnant women participating in a prospective longitudinal community-based study, Little in Norway. Mother-infant interactions were videotaped and scored with the Early Relational Health Screen (ERHS) at 12 months. The Parenting Stress Index (PSI) and Infant-Toddler Social and Emotional Assessment (ITSEA) were administered at 18 months. First, we analyzed response patterns to prenatal risks to identify number and characteristics of latent classes. Second, we investigated whether latent class membership could predict mother-child interactional quality, parenting stress, and child internalizing and externalizing behavior after the child was born. Results revealed three prenatal risk constellations: broad risk (7.52%), mental health risk (21.62%) and low-risk (70.86%). Membership in the broad risk group predicted lower scores on interactional quality, while membership in the mental health risk group predicted less favorable scores on all outcome measures. Prenatal risks clustered together in specific risk constellations that differentially related to parent, child and interactional outcomes.

Maternal social isolation and behavioral problems in preschool children: the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study

It is essential to clarify factors associated with mental health and behavioral problems in early childhood, because children are critical stages of life for mental health. We aimed to prospectively examine the associations between maternal social isolation and behavioral problems in preschool children. We analyzed data from 5842 mother-child pairs who participated in the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study. The Lubben Social Network Scale-abbreviated version was used to assess social isolation (defined as scores < 12) one year after delivery. The Child Behavior Checklist 1½-5 was used to assess behavioral problems, and its subscales were used to assess internalizing and externalizing problems in children at 4 years of age. Multiple logistic regression analyses were conducted to examine the associations between social isolation and behavioral problems, after adjustment for age, education, income, work status, marital status, extraversion, neuroticism, depressive symptoms, child sex, and number of siblings. Multiple logistic regression analyses were also conducted for internalizing problems and externalizing problems. The prevalence of maternal social isolation was 25.4%. Maternal social isolation was associated with an increased risk of behavioral problems in children: the odds ratio (OR) was 1.37 (95% confidence interval [CI] 1.14-1.64). Maternal social isolation was also associated with increased risks of internalizing problems and externalizing problems in children: the ORs were 1.33 (95% CI, 1.12-1.59) and 1.40 (95% CI, 1.18-1.66), respectively. In conclusion, maternal social isolation one year after delivery was associated with behavioral problems in children at 4 years of age.

Teacher Autonomy Support and Internalizing Problems of Adolescents from Divorced and Intact Families: Moderation by Personality Typologies

The present research compared internalizing problems of adolescents who experienced parental divorce with those of adolescents who remained in intact families. Furthermore, this research investigated the association of teacher autonomy support with adolescents' internalizing problems for the whole sample and further ascertained whether this association was moderated by distinctive personality profiles using a person-centered approach and family structures (divorced vs. intact families). A sample of 2756 Chinese adolescents (8.5% from divorced families), aged 13-18 years, participated in the present research. They completed a set of self-reported questionnaires during school hours. Results based on ANCOVA showed that adolescents who experienced parental divorce reported higher internalizing problems than did those who remained in intact families. Moreover, latent profile analysis revealed three personality profiles: psychopathic (22.7%), normative (56.4%), and resilient (20.9%). In addition, teacher autonomy support was negatively related to adolescents' internalizing problems in the overall sample. However, interaction analyses further exhibited that this association was insignificant for psychopathic adolescents who experienced parental divorce. The current findings indicate that although teacher autonomy support may protect adolescents from internalizing problems, psychopathic adolescents whose parents got divorced should be paid exceptional attention by mental health professionals and school counselors.

Effectiveness of a blended school-based mindfulness program for the prevention of co-rumination and internalizing problems in Dutch secondary school girls: a cluster randomized controlled trial

BACKGROUND

A growing body of literature indicates that adolescent girls who talk with close friends about interpersonal problems or worries in an excessive, speculative way, and with an intense focus on distress (i.e., co-rumination) are at heightened risk for developing internalizing symptoms and disorders as well as reduced friendship quality. However, to date, there are no prevention programs available that target high levels of co-rumination between adolescent girls. As such, we developed the blended school-based mindfulness prevention program Happy Friends, Positive Minds (HFPM) that targets co-rumination at the dyadic level, i.e., between two close female friends. The aim of this trial is to evaluate the effectiveness of HFPM to reduce co-rumination and internalizing problems and to enhance wellbeing and social-emotional behavior in Dutch adolescent girls.

METHODS

A cluster Randomized Controlled Trial (cRCT) will be conducted to evaluate HFPM effectiveness. We will recruit 160 female friendship dyads (n = 320 girls) aged 13 to 15 years who will be characterized by high levels of self-reported co-rumination. The cRCT has two arms: (1) an intervention condition in which 160 girls (80 friendship dyads) will receive the 14-week HFPM program in two consecutive cohorts (cohort 1 in academic year 2023/2024 and cohort 2 in academic year 2024/2025, and (2) a control condition in which 160 girls (80 dyads) will receive care-as-usual (CAU) in two consecutive cohorts (cohort 1 in academic year 2023/2024 and cohort 2 in academic year 2024/2025). Data will be collected at baseline (T0), during the program (T1;T2; T3), immediately after the program (T4), and at 1-year follow-up (T5). Participant-level self-reported risk for (early onset) depression and anxiety, self-reported and observed co-rumination, self- and friend-reported friendship quality, self-reported positive and negative affect, self-reported interpersonal responses to positive affect, and self-reported anhedonia symptoms will be the outcome variables.

DISCUSSION

This study will provide insights into the short-term and long-term effects of the HFPM program on girls' internalizing problems, wellbeing, and social-emotional behavior.

Binary and Non-binary Gender Identities, Internalizing Problems, and Treatment Wishes Among Adolescents Referred to a Gender Identity Clinic in Germany

Clinical research on transgender and gender-nonconforming (TGNC) adolescents has focused on binary individuals or often not differentiated among gender identities. Recent studies suggest that a considerable proportion of TGNC adolescents identify as non-binary and that these youth report more internalizing problems as well as different transition-related medical treatment wishes than binary adolescents. However, the results are inconclusive, and data for the German-speaking area are lacking. Therefore, the present study aimed to assess the percentage of binary and non-binary gender identities in a German sample of clinically referred TGNC adolescents and examine associations of gender identity with internalizing problems and transition-related medical treatment wishes. The sample consisted of 369 adolescents (11-18 years, Mage = 15.43; 305 birth-assigned female, 64 birth-assigned male) who attended the Hamburg Gender Identity Service for children and adolescents (Hamburg GIS) between 2013 and 2019. Gender identity and treatment wishes were assessed using study-specific items and internalizing problems using the Youth Self-Report. In total, 90% (n = 332) of the sample identified as binary and 10% (n = 37) as non-binary. Having a non-binary gender identity was significantly associated with more internalizing problems and with wishing for no transition-related medical treatment or only puberty-suppressing hormones. The results underscore that non-binary adolescents represent a specifically vulnerable subgroup within TGNC adolescents with unique mental health needs and treatment wishes. Future research should differentiate among various gender identities. In clinical practice, it is crucial to create an inclusive space for non-binary youth and provide mental health care if needed.

Parenting practices, mental health, and electronic cigarette use among U.S. young adolescents: A longitudinal panel analysis, 2013-2018

PURPOSE

This study examined prospective association of parenting practices related to tobacco use with adolescent e-cigarette use and the moderating role of mental health among U.S. young adolescents.

METHODS

We study used multi-wave longitudinal data (2013-2018) drawn from the Population Assessment of Tobacco and Health Study. A total of 5114 young adolescents (12-14 years) who were not lost to follow-ups across four waves (Wave 1-4) comprised the study sample. Weighted logistic regression models along with generalized linear mixed modeling assessed the within-subject associations of parenting practices related to tobacco use (tobacco availability at parent/guardian's home, past-year parent talk about tobacco use, and rules about non-combustible tobacco use at home) with adolescent current e-cigarette use.

RESULTS

Prevalence of having home rules about non-combustible tobacco use increased (74.5%-80.2%) and that of parent talk about tobacco use decreased (52.0%-33.9%) over time while tobacco availability at home did not show a specific trend. Tobacco availability at home was associated with increased odds of adolescent e-cigarette use (adjusted odd ratio[OR] = 2.25, 95% confidence interval[CI] = 1.72-2.95), and having home rules about non-combustible tobacco use was linked to decreased likelihood of e-cigarette use (adjusted OR = 0.72, 95% CI = 0.55-0.92). The magnitude of negative association between having rules about non-combustible tobacco and adolescent e-cigarette use was stronger among adolescents with internalizing problems but weaker among those with externalizing problems.

CONCLUSIONS

Our findings highlight the important role of home-based interventions in discouraging young adolescents from e-cigarette use. Parents/guardians should consider adolescents' mental health to provide more efficient home- and/or clinical-based e-cigarette use prevention.

Latent Profiles of Sleep Patterns in Early Adolescence: Associations With Behavioral Health Risk

PURPOSE

The present study characterized sleep profiles in a national longitudinal sample of early adolescents and examined whether profiles predicted later behavioral problems.

METHODS

Three waves of data (2016-2021) were obtained from the Adolescent Behavior and Cognitive Development study, including 3,326 participants with both weekday and weekend sleep data measured by Fitbit wearables (age range 10.58-13.67 years; 49.3% female). Latent profile analysis was utilized to identify sleep profiles using multiple sleep indicators (duration, latency, efficiency, wake minutes, wake counts, and midpoint). We then explored whether demographic predictors predicted profile membership and tested the latent sleep profiles' predictive utility of internalizing and externalizing symptoms.

RESULTS

Four profiles were identified: average sleep (40.39%), high duration & high wakefulness (28.58%), high efficiency, low duration &low wakefulness (16.86%), and low duration & low efficiency (14.17%). Participants with older age, males, higher body mass index, and advanced pubertal status were more likely to be classified in the low duration & low efficiency profile than the average group. Participants with lower income, minority identification, older age, and higher body mass index were more likely to be classified in the high efficiency, low duration &low wakefulness than the average group. Participants with lower parental education and males were more likely to be in the high sleep duration & high wakefulness than the average group. The low duration & low efficiency group had the highest attention problems, social problems, and rule-breaking behaviors.

DISCUSSION

Our findings highlight unique sleep patterns in early adolescence and their prospective links with internalizing and externalizing problems.

The Association Between Emotion Recognition and Internalizing Problems in Children and Adolescents: A Three-Level Meta-Analysis

Numerous studies have explored the link between how well youth recognize emotions and their internalizing problems, but a consensus remains elusive. This study used a three-level meta-analysis model to quantitatively synthesize the findings of existing studies to assess the relationship. A moderation analysis was also conducted to explore the sources of research heterogeneity. Through a systematic literature search, a total of 42 studies with 201 effect sizes were retrieved for the current meta-analysis, and 7579 participants were included. Emotion recognition was negatively correlated with internalizing problems. Children and adolescents with weaker emotion recognition skills were more likely to have internalizing problems. In addition, this meta-analysis found that publication year had a significant moderating effect. The correlation between emotion recognition and internalizing problems decreased over time. The degree of internalizing problems was also found to be a significant moderator. The correlation between emotion recognition and internalizing disorders was higher than the correlation between emotion recognition and internalizing symptoms. Deficits in emotion recognition might be relevant for the development and/or maintenance of internalizing problems in children and adolescents. The overall effect was small and future research should explore the clinical relevance of the association.

Online and school bullying roles: are bully-victims more vulnerable in nonsuicidal self-injury and in psychological symptoms than bullies and victims?

BACKGROUND

Bullying leads to adverse mental health outcomes and it has also been linked to nonsuicidal self-injury (NSSI) in community adolescents. It is not clear whether different roles of bullying (bully, victim, bully-victim) are associated with NSSI, furthermore the same associations in cyberbullying are even less investigated.

METHODS

The aim of the current study was to test whether students involved in school or online bullying differed from their not involved peers and from each other in psychological symptoms (externalizing and internalizing problems) and in NSSI severity (number of episodes, number of methods). Furthermore, mediation models were tested to explore the possible role of externalizing and internalizing problems in the association of school and online bullying roles with NSSI. In our study, 1011 high school students (66.07% girls; n = 668), aged between 14 and 20 years (Mage = 16.81; SD = 1.41) participated.

RESULTS

Lifetime prevalence of at least one episode of NSSI was 41.05% (n = 415). Students involved in bullying used more methods of NSSI than not involved adolescents. In general, victim status was associated mostly with internalizing symptoms, while bully role was more strongly associated with externalizing problems. Bully-victims status was associated with both types of psychological problems, but this group did not show a significantly elevated NSSI severity compared to other bullying roles. Externalizing and internalizing problems mediated the relationship between bullying roles and NSSI with different paths at different roles, especially in case of current NSSI that happened in the previous month.

CONCLUSIONS

Results highlight that students involved in bullying are more vulnerable to NSSI and to psychological symptoms compared to their peers who are not involved in bullying. It is suggested that bullying roles, especially bully-victim status, need to be identified in school and online settings and thus special attention should be addressed to them to reduce psychological symptoms and NSSI, for example by enhancing adaptive coping skills.

When is Solitude Maladaptive for Adolescents? A Comprehensive Study of Sociability and Characteristics of Solitude

Research examining the link between solitude and psychosocial adjustment among adolescents has lacked a comprehensive, person-centered examination of differential patterns of both solitude and sociability. The current study surveyed 1071 adolescents (Mage = 12.48, SD = 1.71, 49.86% female, age range = 10-16 years). Using latent-profile analysis, four groups were identified with differential patterns of characteristics of solitude (i.e., enjoyment, motivations, preference, frequency) and sociability. Results indicated that worse psychosocial adjustment across time points was associated with membership in the PFS-NonSociable group (characterized by high enjoyment, preference, and frequency of solitude; low sociability) compared to all other groups. Findings suggest that solitude for adolescents appears to be linked to worse psychosocial adjustment only if accompanied by a lack of sociability.

Associations of behavioral problems with white matter circuits connecting to the frontal lobes in school-aged children born at term and preterm

Introduction

This study investigated whether behavioral problems in children were associated with fractional anisotropy (FA) of white matter tracts connecting from other brain regions to right and left frontal lobes. We considered internalizing and externalizing behavioral problems separately and contrasted patterns of associations in children born at term and very preterm.

Methods

Parents completed the Child Behavior Checklist/6-18 questionnaire to quantify behavioral problems when their children were age 8 years (N=36 FT and 37 PT). Diffusion magnetic resonance scans were collected at the same age and analyzed using probabilistic tractography. We used multiple linear regression to investigate the strength of association between age-adjusted T-scores of internalizing and externalizing problems and mean fractional anisotropy (mean-FA) of right and left uncinate, arcuate, and anterior thalamic radiations, controlling for birth group and sex.

Results

Regression models predicting internalizing T-scores from mean-FA found significant group-by-tract interactions for the left and right arcuate and right uncinate. Internalizing scores were negatively associated with mean-FA of left and right arcuate only in children born at term (pleft AF =0.01, pright AF =0.01). Regression models predicting externalizing T-scores from mean-FA found significant group-by-tract interactions for the left arcuate and right uncinate. Externalizing scores were negatively associated with mean-FA of right uncinate in children born at term (pright UF =0.01) and positively associated in children born preterm (pright UF preterm =0.01). Other models were not significant.

Conclusions

In this sample of children with scores for behavioral problems across the full range, internalizing and externalizing behavioral problems were negatively associated with mean-FA of white matter tracts connecting to frontal lobes in children born at term; externalizing behavioral problems were positively associated with mean-FA of the right uncinate in children born preterm. The different associations by birth group suggest that the neurobiology of behavioral problems differs in the two birth groups.

Longitudinal relationship between social media and e-cigarette use among adolescents: the roles of internalizing problems and academic performance

BACKGROUND

Prior research has investigated the influence of social media on e-cigarette use among adolescents, predominantly through the display of e-cigarette content and advertisements. However, the psychological mechanism underlying this relationship remains underexplored. This study aims to address the mediating effect of youths internalizing problems and elucidate the moderating effect of academic performance from a longitudinal perspective.

METHODS

Panel data from the Public Assessment of Tobacco and Health (PATH) Study Waves 3-5 (2015-2019) were utilized in this study. The sample consisted of 3,975 youths between the ages of 12 and 17 years old. A moderated mediation model was utilized for analyses.

RESULTS

Adolescents using social media more frequently in Wave 3 reported higher odds of internalizing problems in Wave 4 (bp = 0.061, p < .01), which led to more e-cigarette use in Wave 5 (bp = 0.029, p < .01). A negative moderating effect of academic performance was found in the association between internalizing problems and e-cigarette use (bp=-0.088, p < .05).

CONCLUSIONS

Frequent social media use among young individuals leads to an increase in e-cigarette use through enhanced internalizing problems. However, adolescents who perform well academically exhibit higher resistance to e-cigarette use. Based on our findings, we recommend that tailored anti-e-cigarette campaigns and mental health interventions be used to target frequent social media users and academically struggling adolescents to prevent adverse health outcomes.

Association between caregiver and household alcohol use and child behavior problems in KwaZulu Natal, South Africa

We explored the association between household alcohol use and behavior problems among South-African children, using data from the Asenze study, a population-based cohort of South African children and their caregivers. Household alcohol use and child behavior were assessed when children were 6-8 years old. To examine the association, we performed linear regressions. The sample included 1383 children with complete data under the care of 1251 adults. Children living in a household where self-reported caregiver alcohol use was scored as hazardous (4.6%) had higher levels of problem behavior (β = 1.94, 95% CI 0.06-3.82). There were no statistically significant associations between reported hazardous alcohol use by another member of the household (14.5%) and child problem behavior. Hazardous household alcohol use was associated with child problem behavior and this effect appeared to be mainly driven by primary caregiver use.

Internalizing problems before and during the COVID-19 pandemic in independent samples of Dutch children and adolescents with and without pre-existing mental health problems

The aim of the study was to assess internalizing problems before and during the pandemic with data from Dutch consortium Child and adolescent mental health and wellbeing in times of the COVID-19 pandemic, consisting of two Dutch general population samples (GS) and two clinical samples (CS) referred to youth/psychiatric care. Measures of internalizing problems were obtained from ongoing data collections pre-pandemic (NGS = 35,357; NCS = 4487) and twice during the pandemic, in Apr-May 2020 (NGS = 3938; clinical: NCS = 1008) and in Nov-Dec 2020 (NGS = 1489; NCS = 1536), in children and adolescents (8-18 years) with parent (Brief Problem Monitor) and/or child reports (Patient-Reported Outcomes Measurement Information System®). Results show that, in the general population, internalizing problems were higher during the first peak of the pandemic compared to pre-pandemic based on both child and parent reports. Yet, over the course of the pandemic, on both child and parent reports, similar or lower levels of internalizing problems were observed. Children in the clinical population reported more internalizing symptoms over the course of the pandemic while parents did not report differences in internalizing symptoms from pre-pandemic to the first peak of the pandemic nor over the course of the pandemic. Overall, the findings indicate that children and adolescents of both the general and clinical population were affected negatively by the pandemic in terms of their internalizing problems. Attention is therefore warranted to investigate long-term effects and to monitor if internalizing problems return to pre-pandemic levels or if they remain elevated post-pandemic.

Pathways from Polyvictimization to Offline and Online Sexual Harassment Victimization Among South Korean Adolescents

This study aimed to investigate the association between polyvictimization and offline and online sexual harassment and whether the association might be mediated by internalizing problems, low school satisfaction, and dropping out of school. The analytic sample was derived from the Children and Youth Rights Survey in South Korea. It consisted of 6353 adolescents' responses to the sexual harassment question and a set of other questions in the middle and high school questionnaires. The findings showed a direct association between polyvictimization and offline and online sexual harassment. Adolescents who were polyvictimized were more likely to be victims of both forms of sexual harassment. Furthermore, polyvictimization was positively related to dropping out of school, which was positively associated with offline sexual harassment. The findings from the study have significant implications for future research and practice.

The Role of Parenting Stress as a Mediator in the Relationship Between Postpartum Depressive Symptoms and Early Childhood Internalizing Behaviour

Parenting stress occurs when demands of the parenting role are perceived as overwhelming and has been proposed as a mechanism through which postpartum mood disturbances may impact child psychopathology. In a prospective longitudinal birth cohort of 111 birthing parent-child dyads, this study examined whether the relationship between birthing parents' mood symptoms in infancy (3 months postpartum) and their child's internalizing behaviour in early childhood (3 and 6 years old) is mediated by parenting stress at 6 months postpartum. The relationship between higher postpartum mood symptoms at 3 months and increased internalizing behaviour at 3 years of age was mediated by increased reports of parenting stress at 6 months (b = .12, 95% CI = .02, .25). This association was not evident at 6 years. Parenting stress in early infancy may provide a treatment target to reduce the impact of perinatal depression on early child behavior.

Testing an integrated dimensional model of adverse childhood experiences: Associations with COVID-19 outcomes

BACKGROUND

Adverse childhood experiences (ACEs) are a salient risk factor for a myriad of negative outcomes. Extant theoretical and empirical models traditionally quantify the impact of ACEs using cumulative representations. Recent conceptualizations challenge this framework and theorize that the types of ACEs children are exposed to differentially impacts their future functioning.

OBJECTIVE

The current study tested an integrated ACEs model using parent-report of child ACEs across four aims: (1) characterize heterogeneity in child ACEs using a latent class analysis (LCA); (2) examine mean level class differences in COVID specific and COVID non-specific environmental factors (i.e., COVID impact, ineffective parenting, effective parenting) and internalizing and externalizing problems during the COVID pandemic; (3) test interactions between COVID impact and ACEs classes in predicting outcomes, and (4) compare a cumulative risk approach to a class membership approach.

PARTICIPANTS AND SETTING

A nationally representative sample of U.S. parents (N = 796; 51.8 % fathers, M age = 38.87 years, 60.3 % Non-Hispanic White) completed a cross-sectional survey about themselves and one child (5-16 years old) between February-April 2021.

METHOD

Measures of child's ACEs history, COVID impact, effective and ineffective parenting, and children's internalizing and externalizing problems were completed by parents.

RESULTS

A LCA demonstrated three distinct classes of ACEs reflecting low-risk, trauma-risk, and environmental-risk classes. In general, the trauma-risk class had more negative COVID-19 outcomes than the other classes (small to large effect sizes).

CONCLUSIONS

The classes differentially related to outcomes, providing support for dimensions of ACEs and emphasizing the distinct types of ACEs.

Early life stress, prenatal secondhand smoke exposure, and the development of internalizing symptoms across childhood

BACKGROUND

Prior findings relating secondhand tobacco smoke (SHS) exposure and internalizing problems, characterized by heightened anxiety and depression symptoms, have been equivocal; effects of SHS on neurodevelopment may depend on the presence of other neurotoxicants. Early life stress (ELS) is a known risk factor for internalizing symptoms and is also often concurrent with SHS exposure. To date the interactive effects of ELS and SHS on children's internalizing symptoms are unknown. We hypothesize that children with higher exposure to both prenatal SHS and ELS will have the most internalizing symptoms during the preschool period and the slowest reductions in symptoms over time.

METHODS

The present study leveraged a prospective, longitudinal birth cohort of 564 Black and Latinx mothers and their children, recruited between 1998 and 2006. Cotinine extracted from cord and maternal blood at birth served as a biomarker of prenatal SHS exposure. Parent-reported Child Behavior Checklist (CBCL) scores were examined at four timepoints between preschool and eleven years-old. ELS exposure was measured as a composite of six domains of maternal stress reported at child age five. Latent growth models examined associations between SHS, ELS, and their interaction term with trajectories of children's internalizing symptoms. In follow-up analyses, weighted quintile sum regression examined contributions of components of the ELS mixture to children's internalizing symptoms at each time point.

RESULTS

ELS interacted with SHS exposure such that higher levels of ELS and SHS exposure were associated with more internalizing symptoms during the preschool period (β = 0.14, p = 0.03). The interaction between ELS and SHS was also associated with a less negative rate of change in internalizing symptoms over time (β=-0.02, p = 0.01). Weighted quintile sum regression revealed significant contributions of maternal demoralization and other components of the stress mixture to children's internalizing problems at each age point (e.g., age 11 WQS β = 0.26, p < 0.01).

CONCLUSIONS

Our results suggest that prior inconsistencies in studies of SHS on behavior may derive from unmeasured factors that also influence behavior and co-occur with exposure, specifically maternal stress during children's early life. Findings point to modifiable targets for personalized prevention.

The Protective Role of the Autonomic Nervous System in Intergenerational Cycles of Neglect

Offspring of parents who experienced childhood neglect are at increased risk for developing internalizing problems. Empirical evidence suggests this link is principally mediated through parenting behavior. However, such intergenerational cycles of adversity are found to be disrupted in many families. Parasympathetic nervous system functioning is well documented to mediate individuals' emotion regulation biologically. Respiratory sinus arrhythmia (RSA) is a validated biomarker for parasympathetic activity. The goal of the current study was to investigate the moderating role of parent RSA reactivity in the effect of parents' childhood neglect on their children's internalizing problems, through parental acceptance. Physiological and survey data were collected from 145 dyads (94% mothers; Youth Mage = 12.9, Youth SDage = 0.85). Results suggest that the effect of parents' childhood neglect on their child's internalizing problems was conditional on parents' RSA reactivity. Specifically, higher levels of parents' neglect were only linked to increased risk for youth internalizing problems if parents exhibited a lack of RSA withdrawal. Further, this moderating effect was found to be mediated through parental acceptance. Findings suggest understanding intergenerational consequences of child maltreatment contexts should include consideration of bioregulatory factors.

Vagal flexibility to negative emotions moderates the relations between environmental risk and adjustment problems in childhood

Neurobiological and social-contextual influences shape children's adjustment, yet limited biopsychosocial studies have integrated temporal features when modeling physiological regulation of emotion. This study explored whether a common underlying pattern of non-linear change in respiratory sinus arrhythmia (RSA) across emotional scenarios characterized 4-6 year-old children's parasympathetic reactivity (N = 180). Additionally, we tested whether dynamic RSA reactivity was an index of neurobiological susceptibility or a diathesis in the association between socioeconomic status, authoritarian parenting, and the development of externalizing problems (EP) and internalizing problems over two years. There was a shared RSA pattern across all emotions, characterized by more initial RSA suppression and a subsequent return toward baseline, which we call vagal flexibility (VF). VF interacted with parenting to predict EP. More authoritarian parenting predicted increased EP two years later only when VF was low; conversely, when VF was very high, authoritarian mothers reported that their children had fewer EP. Altogether, children's patterns of dynamic RSA change to negative emotions can be characterized by a higher order factor, and the nature by which VF contributes to EP depends on maternal socialization practices, with low VF augmenting and high VF buffering children against the effects of authoritarian parenting.

Sex differences in the effects of prematurity and/or low birthweight on neurodevelopmental outcomes: systematic review and meta-analyses

BACKGROUND

Premature birth and/or low birthweight have long-lasting effects on cognition. The purpose of the present systematic review is to examine whether the effects of prematurity and/or low birth weight on neurodevelopmental outcomes differ between males and females.

METHODS

Web of Science, Scopus, and Ovid MEDLINE were searched for studies of humans born premature and/or of low birthweight, where neurodevelopmental phenotypes were measured at 1 year of age or older. Studies must have reported outcomes in such a way that it was possible to assess whether effects were greater in one sex than the other. Risk of bias was assessed using both the Newcastle-Ottawa scale and the National Institutes of Health Quality assessment tool for observational cohort and cross-sectional studies.

RESULTS

Seventy-five studies were included for descriptive synthesis, although only 24 presented data in a way that could be extracted for meta-analyses. Meta-analyses found that severe and moderate prematurity/low birthweight impaired cognitive function, and severe prematurity/low birthweight also increased internalizing problem scores. Moderate, but not severe, prematurity/low birthweight significantly increased externalizing problem scores. In no case did effects of prematurity/low birthweight differ between males and females. Heterogeneity among studies was generally high and significant, although age at assessment was not a significant moderator of effect. Descriptive synthesis did not identify an obvious excess or deficiency of male-biased or female-biased effects for any trait category. Individual study quality was generally good, and we found no evidence of publication bias.

CONCLUSIONS

We found no evidence that the sexes differ in their susceptibility to the effects of severe or moderate prematurity/low birthweight on cognitive function, internalizing traits or externalizing traits. Result heterogeneity tended to be high, but this reflects that one sex is not consistently more affected than the other. Frequently stated generalizations that one sex is more susceptible to prenatal adversity should be re-evaluated.

Perceived parental depression, intrusive rumination, and internalizing problems: A three-wave longitudinal study in adolescents

Research suggests that perceiving parental depression elicits internalizing problems in adolescents, but certain studies have indicated that adolescents' internalizing problems also increase their perception of parental emotion. To further investigate the inconsistent findings about the nature of this relationship, the current study used longitudinal data to examine the causal association between adolescents' internalizing problems and the parental depression they perceived, as well as the role of intrusive rumination in the relationship. Method: In this longitudinal study, 392 adolescents who experienced the catastrophic Jiuzhaigou earthquake in 2017 were surveyed at three time points after the earthquake: 12 months (T1), 21 months (T2) and 27 months (T3). A cross-lagged panel model was used to carry out the data analysis. Results: Mutual cause-and-effect relationships were found between intrusive rumination and both perceived parental depression and internalizing problems, respectively; a unilateral causal relationship in which internalizing problems positively predicted perceived parental depression was also found. In addition, internalizing problems predicted perceived parental depression via the mediating role of intrusive rumination; similarly, intrusive rumination predicted perceived parental depression via internalizing problems. Conclusions: Internalizing problems were a risk factor for perceived parental depression, and intrusive rumination played an important role in the relationship between internalizing problems and perceived parental depression.

Gender and Racial/Ethnic Disparities in Undergraduate and Graduate Students' Mental Health and Treatment Use Amid the COVID-19 Pandemic

The COVID-19 pandemic has negatively impacted numerous people?s mental health and created new barriers to services. To address the unknown effects of the pandemic on accessibility and equality issues in mental health care, this study aimed to investigate gender and racial/ethnic disparities in mental health and treatment use in undergraduate and graduate students amid the COVID-19 pandemic. The study was conducted based on a largescale online survey (N = 1,415) administered during the weeks following a pandemic-related university-wide campus closure in March 2020. We focused on the gender and racial disparities in current internalizing symptomatology and treatment use. Our results showed that in the initial period of the pandemic, students identified as cis women (p < .001), non-binary/genderqueer (p < .001), or Hispanic/Latinx (p = .002) reported higher internalizing problem severity (aggregated from depression, generalized anxiety, intolerance of uncertainty, and COVID-19-related stress symptoms) compared to their privileged counterparts. Additionally, Asian (p < .001) and multiracial students (p = .002) reported less treatment use than White students while controlling for internalizing problem severity. Further, internalizing problem severity was associated with increased treatment use only in cisgender, non-Hispanic/Latinx White students (pcis man = 0.040, pcis woman < 0.001). However, this relationship was negative in cis-gender Asian students (pcis man = 0.025, pcis woman = 0.016) and nonsignificant in other marginalized demographic groups. The findings revealed unique mental health challenges faced by different demographic groups and served as a call that specific actions to enhance mental health equity, such as continued mental health support for students with marginalized gender identities, additional COVID-related mental and practical support for Hispanic/Latinx students and promotion of mental health awareness, access, and trust in non-White, especially Asian, students are desperately needed.

Intergenerational Effects of Parenting on Children's Internalizing and Externalizing Trajectories: A Latent Growth Model Analysis

Externalizing and internalizing problems in childhood are associated with risk for later psychopathology. It is important to identify antecedents as they may be targets for intervention. In a sample of 501 children (M = 6.07; 54.7% male; 12.4% Hispanic; 12.2% non-White), we leveraged data from a longitudinal study to examine the transmission of parenting behaviors across two generations and its effects on children's internalizing and externalizing outcomes in the subsequent generation. The results suggested transmission of parenting behaviors, confirmed the role of parenting on children's psychopathology, and provided novel evidence of a direct and indirect role of grandparent's caregiving on children's psychopathology via parenting continuity. These findings may inform interventions addressing continuity of parenting behaviors and their subsequent effects.

The Behavioral and Mental Health Benefits of Speaking the Heritage Language within Immigrant Families: The Moderating Role of Family Relations

Understanding the development of behavioral and mental health issues among adolescents, particularly those from immigrant families, is a key area of concern. Many prior studies have focused on the role of societal (country-of-destination) language skills, but we know less about the role played by the use of the heritage language in families. We examined this latter relationship with a focus on changes in heritage language use and internalizing and externalizing problems, and how family relations moderate this relationship. We used the first two waves (2010/2011 and 2011/2012) of the Children of Immigrants Longitudinal Survey in Four European Countries (CILS4EU) data collected from Germany (n = 1614; M_age = 14.8 years, 50% female), the Netherlands (n = 1203; M_age = 14.7 years, 54% female), Sweden (n = 1794; M_age = 14.2 years, 53% female), and England (n = 1359; M_age = 14.6 years, 50% female). Our results suggest that increased use of heritage language is associated with fewer externalizing problems only in families with greater family cohesion and parental warmth (in Germany and the U.K.) and with fewer internalizing problems only in families with higher parental monitoring (in the Netherlands and Sweden). Good family relations are thus an important precondition for increased heritage language use to lead to improved behavioral and mental health for children of immigrants.

Maternal history of maltreatment and offspring's emotional and behavioral problems in adolescence: Do family factors contribute to the intergenerational risk transmission?

BACKGROUND

A history of childhood maltreatment often has a negative and long-lasting impact across different domains in life. A childhood maltreatment experience in parents may even affect the next generation. So far, the effects of family factors have been considered in the intergenerational transmission of adversity across the childhood years, but whether the effects remain until adolescence is less clear.

OBJECTIVE

Using data from a large population-based study in the Netherlands, including both mother and child reports, we examined whether maternal childhood maltreatment history is associated with increased mental health problems in offspring and the role of family functioning and harsh parenting as a potential pathway.

PARTICIPANTS

4912 adolescents (aged 13 years) and their mothers were recruited in the Generation R study.

METHODS

Mothers reported childhood maltreatment experiences using the Childhood Trauma Questionnaire (CTQ), and adolescents reported on their mental health using the Youth Self Report (YSR). Structural equation modeling (SEM) was used to test the association of maternal childhood maltreatment on mental health problems in offspring and family functioning and harsh parenting as mechanisms to explain this association.

RESULTS

Adolescents of mothers with a history of maltreatment had greater internalizing (β = 0.07, p < .01) and externalizing problems (β = 0.08, p < .01). Moreover, we found an indirect effect via family functioning over time and harsh parenting at ages 3 and 8 years which mediated this association.

CONCLUSION

We concluded an intergenerational effect of maternal childhood maltreatment on adolescents internalizing and externalizing problems. The findings might enable earlier intervention within the family context to mitigate the consequences of maternal childhood maltreatment.

Internalizing and externalizing problems mediate the relationship between maltreatment and self-harm among UK adolescents

BACKGROUND

Maltreatment is a significant predictive factor for self-harm in adolescents. Internalizing and externalizing problems are both common psychopathological issues in adolescents. This study aimed to look into the link between maltreatment and self-harm in a large sample of adolescents in the UK, as well as the mediating effects that internalizing and externalizing problems play in this link.

METHODS

Data were pulled from the UK Millennium Cohort Study, and a total of 8894 adolescents were included in this analysis. All variables were assessed by Questionnaires. Path analysis was performed to assess the mediating effects of internalizing and externalizing problems in the link between maltreatment and self-harm.

RESULTS

23.4 % of samples reported self-harm incidents during the preceding 12 months. Emotional abuse and physical abuse were significantly related to self-harm, and adolescents who had experienced multiple forms of maltreatment were more prone to self-harm. Mediation analysis revealed that internalizing problems were the primary mediator in the link between emotional abuse and self-harm, with the mediation effect size being 0.29. Internalizing and externalizing problems performed similarly in the link between physical abuse and self-harm, with mediation effect sizes of 0.23 and 0.19, respectively.

LIMITATIONS

The majority of the data was gathered through self-reporting.

CONCLUSIONS

Emotional abuse and physical abuse were significant predictors of self-harm, and their links with self-harm were partially mediated via internalizing and externalizing problems. Better supervision of maltreatment, and timely intervention for both internalizing and externalizing problems, are critical in preventing self-harm among adolescents.

Externalizing and internalizing problems as predictors of alcohol-related harm and binge drinking in early adolescence: The role of gender

BACKGROUND

Externalizing problems are commonly associated with alcohol outcomes in adolescence. Nevertheless, findings regarding internalizing problems are mixed, and fewer longitudinal studies have considered the both problems concomitantly and the role of gender. We examined the role of externalizing and internalizing problems in predicting adolescent alcohol-related harm and binge drinking, taking into account the gender differences. We also evaluated if externalizing problems could moderate the association between internalizing problems and alcohol outcomes.

METHOD

We used longitudinal data from 2368 8th grade students across 37 public schools in three Brazilian cities. Linear and logistic regressions were performed to analyze the association between alcohol outcomes and the independent variables (externalization and internalization scores, and sociodemographic variables) according to gender. We also tested the same model with an interaction term between externalizing*internalizing.

RESULTS

Our results suggest that externalizing problems predict adolescents' binge drinking in both genders; it also may predict adolescents' alcohol-related harms, but only in boys. Internalizing problems seem to be a gender-specific risk factor for binge drinking among girls. All findings are independent of comorbid problems and sociodemographic variables.

LIMITATION

The findings should be considered taking into account the short follow-up period from risk factors to the outcomes.

CONCLUSION

Our results highlight the contribution of internalizing and externalizing problems to the development of alcohol-related harm and binge drinking in early adolescence and the need for interventions to prevent early behavioral problems that consider the role played by gender.

Developmental cascades of behavior problems and cognitive ability from toddlerhood to middle childhood: A 9-year longitudinal study

Little is known about the direction, ordering, and uniqueness of longitudinal associations between behavior problems and cognitive ability, from toddlerhood to middle childhood. A developmental cascade model was tested in the present study to examine the transactional processes in 103 Chinese children at the ages of 1, 2, 7, and 9 years. Behavior problems were assessed using the maternal reported Infant-Toddler Social and Emotional Assessment at the ages of 1, 2 and parental reported Children Behavior Checklist at the ages of 7, 9. Cognitive ability was measured using Bayley Scales of Infant and Toddler Development at the ages of 1, 2 and Wechsler Intelligence Scale for Children at the ages of 7, 9. The results revealed the stability of behavior problems and cognitive ability from age 1 to age 9 years and concurrent associations between externalizing and internalizing problems. Unique longitudinal associations were identified between (1) age 1 cognitive ability and age 2 internalizing problems, (2) age 2 externalizing problems and age 7 internalizing problems, (3) age 2 externalizing problems and age 7 cognitive ability, (4) age 7 cognitive ability and age 9 externalizing problems. The results indicated essential targets for future interventions aimed at reducing children's behavior problems at 2 years old and promoting cognitive ability at 1 year old and 7 years old.

Self-esteem, self-efficacy, and social support mediate the relationship between motor proficiency and internalizing problems in adults: Exploring the environmental stress hypothesis in adulthood

The Environmental Stress Hypothesis (ESH) is a theoretical model used to understand the factors mediating the relationship between motor proficiency and internalizing problems. The aim of this study is to explore a potential extension of the ESH by examining whether BMI, physical activity levels, self-esteem, self-efficacy and social support are potential mediators between motor proficiency and internalizing problems in young adults. 290 adults aged between 18 and 30 years old (150 women, 140 men) were evaluated with the following instruments: Adult Developmental Coordination Disorders Checklist (ADC), Depression, Anxiety and Stress Scale (DASS 21), Social Support Satisfaction Scale (SSSS), Perceived General Self-Efficacy Scale (GSE), Rosenberg Self-Esteem Scale (RSES), International Physical Activity Questionnaire (IPAQ), and self-reported body mass index (BMI). The results indicated that self-esteem, self-efficacy, and social support mediate the relationship between motor proficiency and internalizing problems in this sample. Thus, the findings reinforce the notion that early intervention and preventive psychological care can serve as protective aspects of mental health in adults at risk for low motor proficiency.

Associations of Behavioral Problems and White Matter Properties of the Cerebellar Peduncles in Boys and Girls Born Full Term and Preterm

Accumulating evidence suggests that the role of cerebellum includes regulation of behaviors; cerebellar impairment may lead to behavioral problems. Behavioral problems differ by sex: internalizing problems are more common in girls, externalizing problems in boys. Behavioral problems are also elevated in children born preterm (PT) compared to children born full term (FT). The current study examined internalizing and externalizing problems in 8-year-old children in relation to sex, birth-group, fractional anisotropy (FA) of the three cerebellar peduncles (superior, middle, and inferior), and interactions among these predictor variables. Participants (N = 78) were 44 boys (28 PT) and 34 girls (15 PT). We assessed behavioral problems via standardized parent reports and FA of the cerebellar peduncles using deterministic tractography. Internalizing problems were higher in children born PT compared to children born FT (p = .032); the interaction of sex and birth-group was significant (p = .044). When considering the contribution of the mean-tract FA of cerebellar peduncles to behavioral problems, there was a significant interaction of sex and mean-tract FA of the inferior cerebellar peduncle (ICP) with internalizing problems; the slope was negative in girls (p = .020) but not in boys. In boys, internalizing problems were only associated with mean-tract FA ICP in those born preterm (p = .010). We found no other significant associations contributing to internalizing or externalizing problems. Thus, we found sexual dimorphism and birth-group differences in the association of white matter metrics of the ICP and internalizing problems in school-aged children. The findings inform theories of the origins of internalizing behavioral problems in middle childhood and may suggest approaches to treatment at school age.

Maternal postnatal bonding disorder and emotional/behavioral problems in preschool children: The Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study

BACKGROUND

Although there is evidence that maternal perinatal mental disorders are associated with emotional/behavioral problems in children, the long-term impacts of postnatal bonding disorder remain unclear. We aimed to examine the associations between maternal postnatal bonding disorder and emotional/behavioral problems in preschool children.

METHODS

We analyzed data from 7220 mother-child pairs who participated in the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study. Maternal bonding disorder was defined as Mother-to-Infant Bonding Scale score ≥5 at 1 month after delivery. The Child Behavior Checklist for Ages 1½-5 was used to assess emotional/behavioral problems, and its subscales were used to assess internalizing and externalizing problems in children at 4 years of age. Multiple logistic regression analyses were conducted to examine the associations of postnatal bonding disorder with emotional/behavioral, internalizing, and externalizing problems after adjustment for age, education, income, parity, prenatal psychological distress, postnatal depressive symptoms, child's sex, preterm birth, and birth defects.

RESULTS

The prevalence of postnatal bonding disorder was 14.8 %. Postnatal bonding disorder was associated with an increased risk of emotional/behavioral problems in children: the odds ratio (OR) was 2.06 (95 % confidence interval [CI], 1.72-2.46). Postnatal bonding disorder was also associated with increased risks of internalizing problems and externalizing problems in children: the ORs were 1.69 (95 % CI, 1.42-2.02) and 1.90 (95 % CI, 1.59-2.26), respectively.

LIMITATIONS

Bonding and problems were self-reported.

CONCLUSIONS

Bonding disorder at 1 month after delivery was associated with an increased risk of emotional/behavioral problems in children at 4 years of age.

Students' Perceptions of COVID-19 Stress and Internalizing Problems: Is Social Support a Buffer?

The current study investigated the associations among student perceptions of COVID-19 stress, internalizing problems, and school social support (teacher and classmate support) and how these relations differed across elementary/middle and high school students. Based on data from 526 4th- through 12th-grade students from a school district in the Northeast, we found that COVID-19-related stress was significantly related to internalizing problems for all students, regardless of grade level. We also found that teacher social support, but not classmate social support, buffered the positive relation between COVID-19 stress and internalizing problems. The results of the current study have implications for school psychologists, counselors, social workers, and other educators in alleviating COVID-19-related stress in students and associated symptoms of internalizing problems in students. As the pandemic unwinds, future research should examine the long-term impacts of the COVID-19 pandemic, especially for students with marginalized identities, and how teacher and/or peer support may play a role in buffering these stressors for students.

Meta-analyses of the associations of mentalization and proxy variables with anxiety and internalizing problems

Mentalization, the high-order function of detecting and interpreting one's own and others' mental states, has gained interest in the fields of clinical and developmental psychopathology. However, little is known about mentalization's associations with anxiety and broader internalizing problems. Using the framework of the multidimensional model of mentalization, the aim of this meta-analysis was to quantify the strength of the association between mentalization and anxiety/internalizing problems and to identify potential moderators of this association. A systematic review of the literature led to the inclusion of 105 studies (N = 19,529) covering all age groups. The global effect analysis showed a small negative association between mentalization and the overall anxious and internalizing symptomatology (r = -0.095, p = .000). Various effect sizes were found for associations between mentalization and specific outcomes (unspecified anxiety, social anxiety, generalized anxiety, and internalizing problems). The methods of assessment of mentalization and anxiety moderated their association. Findings support the presence of modest impairments in the mentalizing capacities of anxious individuals, likely influenced by their vulnerability to stress and the context in which they mentalize. Further studies are needed to draw a clear profile of mentalizing capacities with regard to specific anxious and internalizing symptomatologies.

Relational Victimization, Characterological Self-Blame, and Adjustment in Young Children

The associations between relational victimization, self-blame attributions, and internalizing problems in early childhood has not previously been examined. Using a sample of 116 preschool children, average age 44.05 months (SD = 4.23), multiple informants, multiple methods, and a longitudinal design, path analyses were conducted to explore the associations between relational victimization, self-blame attributions (Characterological Self-Blame[CSB] and Behavioral Self-Blame[BSB]), and maladjustment in early childhood. Concurrent significant associations were found between relational victimization and internalizing problems. The initial longitudinal models revealed some significant effects that were consistent with predictions. Importantly, follow-up tests decomposing internalizing problems, indicated that anxiety at Time 1 was positively and significantly associated with CSB at Time 2. Depression at Time 1 was negatively and significantly associated with CSB at Time 2. Implications of this work are discussed.

Association between short- and long-term exposures to air pollutants and internalizing/externalizing behavior in children aged 4 to 7 years

The effects of air pollutants on psychological health have attracted increasing attention worldwide. However, there is limited evidence on the association between air pollution and children's psychological development. This study explores the association between short- and long-term exposures to air pollutants and children's internalizing and externalizing behaviors. A total of 2303 children of 4-7 years were included in this study. We assessed their behavior using the Child Behavior Checklist (4-16 years). The prevalence of internalizing and externalizing behavior was 4.77% and 4.43%, respectively. For short-term exposure, CO pollution was associated with children's internalizing behaviors, with each 1 mg/m³ increment leading to an odds ratio (OR) of 1.063 (95% CI 1.005, 1.124), 1.065 (95% CI 1.009, 1.124), 1.067 (95% CI 1.007, 1.131), and 1.122 (95% CI 1.018, 1.236) at lag04, lag05, lag06, and lag0120, respectively. O₃ (per 1 g[Formula: see text]/m³) was negatively associated with internalizing problems at lag2 [OR = 0.991 (95% CI 0.983, 0.999)]. NO₂ (per 1 g[Formula: see text]/m³) was significantly associated with externalizing behaviors, with the ORs of 1.067 (95% CI 1.024, 1.111) at lag060 and 1.060 (95% CI 1.010, 1.113) at lag0120. For long-term exposure, it indicated that 1-year exposure to CO (per 1 mg/m³) and PM_2.5 (per 1 g[Formula: see text]/m³) was positively associated with internalizing behavioral risk [OR = 1.724 (95% CI 1.187, 2.504); PM_2.5: OR = 1.236 (95% CI 1.114, 1.371)], whereas NO₂ (per 1 g[Formula: see text]/m³) exposure was associated with an increased risk of externalizing behavior [OR = 1.123 (95% CI 1.003, 1.256)]. In addition, the interaction analysis showed that boys were at a higher risk of abnormal behaviors associated with long-term exposure to CO, PM_2.5, and NO₂. Our findings reveal a potential link between air pollution exposure and abnormal behaviors in kindergarten children after short-/long-term exposure, which is an essential supplement to the studies on the association between air pollution and children's behavioral problems.

Longitudinal association of family conflict and suicidal behaviors among Chinese adolescents: The mediation effect of internalizing and externalizing problems

OBJECTIVE

Family conflict is a risk factor for suicidal behaviors among adolescents. However, few longitudinal studies have investigated this association and explored the mediation effect of behavioral and emotional problems. This study aimed to examine the longitudinal association between family conflict, internalizing and externalizing problems, and suicidal behaviors in a large sample of Chinese adolescents.

METHOD

This longitudinal study of 7,072 adolescents was based on the Shandong Adolescent Behavior & Health Cohort (SABHC). Participants completed a self-administrated questionnaire to assess family conflict, internalizing and externalizing problems, suicidal behaviors, and family demographics at baseline. Excluding adolescents with any suicidal behavior at baseline (N = 839), others (N = 6,233) were allowed to report their internalizing and externalizing problems and suicidal behaviors one-year later. Path analyses were conducted to examine the mediation relationship of internalizing and externalizing problems between family conflict and suicidal behaviors.

RESULTS

Of 6,233 participants, mean age was 14.52 at baseline and 51.2% were males. Adolescents with subsequent suicidal behaviors reported higher scores in family conflict, internalizing and externalizing problems (Ps < 0.01). Path analyses showed that internalizing and externalizing problems played a significant mediating role in the associations of family conflict with suicidal behaviors after adjusting for covariates.

CONCLUSIONS

Family conflict is associated with suicidal behaviors in adolescents, which is partially mediated by internalizing and externalizing problems. Internalizing problems is the major mediator between family conflict and suicidal thought or suicide plan; however, internalizing and externalizing problems play similar mediating roles in the family conflict-suicide attempt link.

Poverty, social exclusion, and mental health: the role of the family context in children aged 7-11 years INMA mother-and-child cohort study

Mental health problems are common in childhood and tend to be more frequent in populations at risk of poverty or social exclusion (AROPE). The family environment can play a role in reducing the impact of economic hardship on these problems. The aim of this study was to assess the effect of multidimensional poverty on the mental health of children aged 7-11 years and the role of the family environment in two areas of Spain. Participants were 395 and 382 children aged 7 and 11 from Gipuzkoa and Valencia, respectively. Internalizing and externalizing problem scales of the child behaviour checklist (CBCL) were used. AROPE indicators were obtained by questionnaire, and three dimensions of the family context (Organization of the Physical Environment and Social Context, Parental Stress and Conflict, and Parental Profile Fostering Development) were measured through subscales 3, 4 and 5 of the Haezi-Etxadi family assessment scale (7-11) (HEFAS 7-11), respectively. Data were analysed using negative binomial regression and Structural Equation Modelling. AROPE prevalence was 7.1 and 34.5% in Gipuzkoa and Valencia, respectively. In both cohorts, there was a significant increase in internalizing and externalizing problems among participants with a higher AROPE score. However, AROPE did not affect internalizing problems in children from families living in a better physical environment and with social support (Subscale 3). The AROPE effect was jointly mediated by subscales 4 and 5 in 42 and 62% of internalizing and externalizing problems, respectively. Preventing economic inequities by economic compensation policies, improving the neighbourhood and immediate environment around the school, and promoting positive parenting programmes can improve mental health in childhood.

Bullying Victimization, Future Orientation, and Suicidal Ideation of African American Youth in an Under-Resourced Community: A Moderated-Mediation Approach

African American youth living in low-resourced communities are at high risk for bullying victimization which is positively associated with suicidal ideation. This study explored whether positive future orientation mediated the relationship between bullying victimization and suicidal ideation. This study engaged 627 African American adolescents and measured bullying victimization, internalizing problems, suicidal ideation, future orientation, and several covariates. Major findings indicated that controlling for gender, socioeconomic status, school motivation, and perceived teacher support, internalizing problems mediated the relationship between bullying victimization and suicidal ideation. Furthermore, both the effect of bullying victimization on suicidal ideation and the mediating effect of internalizing problems were moderated by future orientation. The effects were weakened when the level of future orientation increased. The implications for future research and supporting resiliency are discussed based on these findings.

Lifetime poly-victimization and later bullying victimization: Associations with internalizing problems and out-of-home care

BACKGROUND

Many youth in out-of-home care (OOHC) have experienced victimization in their lifetime making them vulnerable to mental health problems and further victimization. However, little is known about mechanisms behind this continuing victimization, e.g. in the form of bullying victimization, and about possible mediating and moderating factors.

OBJECTIVE

This study examined the association between lifetime poly-victimization and later bullying victimization, as well as mediation by internalizing problems, and moderation by OOHC.

PARTICIPANTS AND SETTING

In total n = 226 youth (n = 117 OOHC, n = 109 biological families) participated, with one of their social/biological caregivers when possible, resulting in subsamples of n = 159 participants (11-21 years) for self-report, and n = 210 participants (8-21 years) for caregiver report.

METHODS

An online survey assessed self-report of bullying victimization in the past six months, as well as self-report and caregiver report of lifetime poly-victimization and internalizing problems.

RESULTS

Based on both self-report and caregiver report, youth in OOHC showed higher levels of poly-victimization and internalizing problems than youth in biological families. In self-report, a conditional direct effect of lifetime poly-victimization on bullying victimization was found for youth in OOHC, c' = 0.18, SE = 0.07, p = .007, while the association was mediated by internalizing problems for youth in biological families, ab = 0.13, 95 % CI [0.020; 10.805]. In the caregiver report, there was neither a direct nor a mediated effect of lifetime poly-victimization on bullying victimization.

CONCLUSIONS

The results stress the importance of considering the high impact of poly-victimization in predicting bullying victimization, particularly for youth in OOHC. For youth in biological families, a mediating effect of internalizing problems was found.

DNA methylation as a mediator in the association between prenatal maternal stress and child mental health outcomes: Current state of knowledge

BACKGROUND

Prenatal maternal stress is increasingly recognized as a risk factor for offspring mental health challenges. DNA methylation may be a mechanism, but few studies directly tested mediation. These few integrative studies are reviewed along with studies from three research areas: prenatal maternal stress and child mental health, prenatal maternal stress and child DNA methylation, and child mental health and DNA methylation.

METHODS

We conducted a narrative review of articles in each research area and the few published integrative studies to evaluate the state of knowledge.

RESULTS

Prenatal maternal stress was related to greater offspring internalizing and externalizing symptoms and to greater offspring peripheral DNA methylation of the NR3C1 gene. Youth mental health problems were also related to NR3C1 hypermethylation while epigenome-wide studies identified genes involved in nervous system development. Integrative studies focused on infant outcomes and did not detect significant mediation by DNA methylation though methodological considerations may partially explain these null results.

LIMITATIONS

Operationalization of prenatal maternal stress and child mental health varied greatly. The few published integrative studies did not report conclusive evidence of mediation by DNA methylation.

CONCLUSIONS

DNA methylation likely mediates the association between prenatal maternal stress and child mental health. This conclusion still needs to be tested in a larger number of integrative studies. Key empirical and statistical considerations for future research are discussed. Understanding the consequences of prenatal maternal stress and its pathways of influence will help prevention and intervention efforts and ultimately promote well-being for both mothers and children.

The occurrence of internalizing problems and chronic pain symptoms in early childhood: what comes first?

Chronic pain and internalizing problems are characterized by concurrent associations but the directionality of this relationship in early childhood remains unclear. This prospective study aimed to investigate the bidirectional effect of chronic pain and internalizing problems and test the persistence of pain over time in a population-based sample of preschoolers. The study was embedded in Generation R, a large population-based cohort. Mothers of 3,996 children assessed their child's experienced pain and internalizing problems at 3 and 6 years. At 3 years, paternal reports were available too. Reports of family functioning, discipline practices and parental psychopathology were also collected. The prevalence of chronic pain was 2.7% (106) and 8.0% (294) at baseline and follow-up, respectively. The presence of internalizing problems at child age 3 years predicted chronic pain at 6 years, for both maternal (OR 1.05, 95% CI 1.02,1.07, p < 0.001) and paternal (OR 1.03, 95%CI 1.00, 1.06, p < 0.05) internalizing problem reports, when adjusted for potential confounding factors. In contrast, chronic pain did not increase the likelihood of internalizing problems. The temporal relationship between chronic pain and internalizing problems appears to follow a largely unidirectional trend in early childhood, with internalizing problems increasing the likelihood of concurrent physical symptoms. Current understanding of the directionality of this relationship, highlights the importance for comprehensive assessment of psychiatric problems contributing to the manifestation of chronic pain.

The role of environmental sensitivity in the development of rumination and depressive symptoms in childhood: a longitudinal study

Some children are more affected than others by their upbringing due to their increased sensitivity to the environment. More sensitive children are at heightened risk for the development of internalizing problems, particularly when experiencing unsupportive parenting. However, little is known about how the interplay between children's sensitivity and parenting leads to higher levels of depressive symptoms. In the current study, we investigated the interaction between early parenting and children's sensitivity on levels of depressive symptomatology in middle childhood, exploring the role of rumination as a possible mediator in a community sample. Participants included 196 USA resident families, from a middle class and mostly European-American background, and their healthy children, followed up from age 3 until 9 and 12 years. Environmental sensitivity was assessed observationally when children were 3 years old. Parenting style was based on parent-report at the age of 3 years. When children were nine, they completed questionnaires on rumination and depressive symptoms (repeated at 12 years). Analyses were run applying a Bayesian approach. Children's sensitivity interacted with permissive parenting in predicting rumination at age 9. Rumination, in turn, was associated with depressive symptoms at age 9 and, to a lesser extent, at age 12. No relevant interactions emerged for authoritative and authoritarian parenting. Sensitive children may be at heightened risk for internalizing problems when exposed to a permissive parenting style. Permissive parenting was associated with increased ruminative coping strategies in sensitive children which, in turn, predicted higher levels of depression. Hence, rumination emerged as an important cognitive risk factor for the development of depressive symptoms in sensitive children.
