Risk of conduct and oppositional defiant disorder symptoms in offspring of parents with mental health problems: Findings from the Raine Study

Low neurocognitive performance and problematic contexts: interaction influences in predicting adolescent externalizing behaviors within a community sample

Research has identified neurocognitive and contextual risk factors of externalizing behaviors. However, fewer studies have examined the interaction among neurocognitive and other risk factors in predicting externalizing behaviors. The goal of the current study was to examine the relation between neurocognitive and contextual factors in predicting externalizing behaviors in a community sample of adolescents. Participants were 84 adolescents, aged 11-17 (M = 13.39, SD = 1.82), recruited as part of a larger study. Separate moderated multiple regression models were utilized in which neurocognitive variables (intellectual functioning, short-term memory/attention, disinhibition) were added as predictors and contextual variables (family dysfunction and parental depression, anxiety, and stress) were added as moderators in step 1, and their interaction was added in step 2. Externalizing behaviors served as criterion variables (hyperactivity/impulsivity and oppositional defiant disorder symptom severity, reactive and proactive aggression). Overall, results suggest that higher levels of problematic contextual factors exacerbate the significant negative associations among neurocognitive functioning and externalizing behaviors. Importantly, this pattern was shown across neurocognitive domains and contextual factors. Findings suggest that contextual factors should be targeted for the treatment or prevention of youth externalizing behaviors, particularly for adolescents with neurocognitive vulnerabilities.

Estimating the Heterogeneous Causal Effects of Parent-Child Relationships among Chinese Children with Oppositional Defiant Symptoms: A Machine Learning Approach

Oppositional defiant symptoms are some of the most common developmental symptoms in children and adolescents with and without oppositional defiant disorder. Research has addressed the close association of the parent-child relationship (PCR) with oppositional defiant symptoms. However, it is necessary to further investigate the underlying mechanism for forming targeted intervention strategies. By using a machine learning-based causal forest (CF) model, we investigated the heterogeneous causal effects of the PCR on oppositional defiant symptoms in children in Chinese elementary schools. Based on the PCR improvement in two consecutive years, 423 children were divided into improved and control groups. The assessment of oppositional defiant symptoms (AODS) in the second year was set as the dependent variable. Additionally, several factors based on the multilevel family model and the baseline AODS in the first year were included as covariates. Consistent with expectations, the CF model showed a significant causal effect between the PCR and oppositional defiant symptoms in the samples. Moreover, the causality exhibited heterogeneity. The causal effect was greater in those children with higher baseline AODS, a worse family atmosphere, and lower emotion regulation abilities in themselves or their parents. Conversely, the parenting style played a positive role in causality. These findings enhance our understanding of how the PCR contributes to the development of oppositional defiant symptoms conditioned by factors from a multilevel family system. The heterogeneous causality in the observation data, established using the machine learning approach, could be helpful in forming personalized family-oriented intervention strategies for children with oppositional defiant symptoms.

Umbrella Review of the Global Prevalence of Conduct Disorder in Children and Adolescents

With the ever-increasing prevalence of mental health issues worldwide, a robust synthesis of existing epidemiological data on the prevalence of Conduct disorder (CD) in children and adolescents is needed to strengthen the knowledge base. This quantitative umbrella review aims to provide a robust synthesis of evidence on the prevalence of CD children and adolescents from meta-analytic systematic reviews. We searched PubMed, Web of Science, PsychINFO, and Scopus to identify relevant articles. The study protocol has been registered with PROSPERO (CRD42023447620). The methodological quality of the studies was evaluated by using a Measurement Tool to Assess Systematic Reviews (AMSTAR). Invariance variance weighted random-effect meta-analysis was performed to pool prevalence estimates from the included articles. Seven meta-analyses, encompassing 138 primary studies and slightly over 48 million CD cases were included in this umbrella review. The quantitative analysis of these studies found a pooled prevalence of CD 3.0% (95%CI 2.0-5%) in children and adolescents, based on random effect meta-analyses. In a stratified analysis, the prevalence estimate of CD was 2.6 times higher in boys compared to girls. Evidence from our quantitative umbrella review showed that the prevalence of CD is relatively high in children and adolescents with boys 2.6 times more likely to experience the disorders when compared to girls. Our findings underlie that attention should be given to preventing, identifying, and treating CD in children and adolescents.

Do parent-reported early indicators predict later developmental language disorder? A Raine Study investigation

BACKGROUND

Developmental language disorder (DLD) is one of the most common neurodevelopmental conditions. Due to variable rates of language growth in children under 5 years, the early identification of children with DLD is challenging. Early indicators are often outlined by speech pathology regulatory bodies and other developmental services as evidence to empower caregivers in the early identification of DLD.

AIMS

To test the predictive relationship between parent-reported early indicators and the likelihood of children meeting diagnostic criteria for DLD at 10 years of age as determined by standardized assessment measures in a population-based sample.

METHODS

Data were leveraged from the prospective Raine Study (n = 1626 second-generation children: n = 104 with DLD; n = 1522 without DLD). These data were transformed into 11 predictor variables that reflect well-established early indicators of DLD from birth to 3 years, including if the child does not smile or interact with others, does not babble, makes only a few sounds, does not understand what others say, says only a few words, says words that are not easily understood, and does not combine words or put words together to make sentences. Family history (mother and father) of speech and language difficulties were also included as variables. Regression analyses were planned to explore the predictive relationship between this set of early indicator variables and likelihood of meeting DLD diagnostic criteria at 10 years.

RESULTS

No single parent-reported indicator uniquely accounted for a significant proportion of children with DLD at 10 years of age. Further analyses, including bivariate analyses testing the predictive power of a cumulative risk index of combined predictors (odds ratio (OR) = 0.95, confidence interval (CI) = 0.85-1.09, p = 0.447) and the moderating effect of sex (OR = 0.89, CI = 0.59-1.32, p = 0.563) were also non-significant.

CONCLUSIONS

Parent reports of early indicators of DLD are well-intentioned and widely used. However, data from the Raine Study cohort suggest potential retrospective reporting bias in previous studies. We note that missing data for some indicators may have influenced the results. Implications for the impact of using early indicators as evidence to inform early identification of DLD are discussed.

WHAT THIS PAPER ADDS

What is already known on the subject DLD is a relatively common childhood condition; however, children with DLD are under-identified and under-served. Individual variability in early childhood makes identification of children at risk of DLD challenging. A range of 'red flags' in communication development are promoted through speech pathology regulatory bodies and developmental services to assist parents to identify if their child should access services. What this paper adds to the existing knowledge No one parent-reported early indicator, family history or a cumulation of indicators predicted DLD at 10 years in the Raine study. Sex (specifically, being male) did not moderate an increased risk of DLD at 10 years in the Raine study. Previous studies reporting on clinical samples may be at risk of retrospective reporting bias. What are the potential or actual clinical implications of this work? The broad dissemination and use of 'red flags' is well-intentioned; however, demonstrating 'red flags' alone may not reliably identify those who are at later risk of DLD. Findings from the literature suggest that parent concern may be complemented with assessment of linguistic behaviours to increase the likelihood of identifying those who at risk of DLD. Approaches to identification and assessment should be considered alongside evaluation of functional impact to inform participation-based interventions.

Comorbid Psychiatric Symptom Associated With Oppositional Defiant Symptom in Community School-Age Children

Objectives

Oppositional defiant disorder (ODD) is often comorbid with other psychiatric disorders in childhood. This study aimed to investigate comorbid psychiatric symptoms and associated factors in elementary school children with symptoms of ODD.

Methods

The participants consisted of 205 mother-offspring pairs. Psychiatric symptoms were measured using the Diagnostic Predictive Scales and Korean Child Behavior Checklist. Psychiatric comorbid symptoms were compared between children with ODD symptom and those without ODD symptom. Multivariate logistic regression analysis was used to estimate the odds ratio of psychiatric symptom on ODD.

Results

ODD group had a significant association with internalizing and externalizing problem (p=0.001, p<0.001, respectively). ODD group were more comorbid with anxiety disorder, depressive disorder, attention-deficit/hyperactivity disorder, and conduct disorder. Among psychiatric disorder, generalized anxiety disorder (GAD) (adjusted odds ratio [AOR]=18.620, p<0.001) and conduct disorder (AOR=9.529, p=0.014) were associated with ODD symptom.

Conclusion

These findings suggest that children with ODD symptom had significantly higher rates of comorbid psychiatric symptoms. And GAD and conduct disorder are related to ODD symptom.

The Effectiveness of Interventions for the Prevention or Treatment of Paternal Perinatal Anxiety: A Systematic Review

Background: The worldwide prevalence of paternal perinatal anxiety (PPA) ranges between 3.4% and 25.0% antenatally, and 2.4% and 51.0% postnatally. Experiencing PPA can adversely impact the individual, partners, and infants. Research concerning PPA is lagging and fragmented compared to research for new mothers. Objectives: To establish the effectiveness of prevention or treatment interventions for PPA in adults identifying as male. Data sources: We completed searches of Medline, EMBASE, PsycINFO and Web of Science from inception to 2 December 2021, as well as hand searches of references from relevant papers. Search selection and data extraction: Randomised controlled trials delivering prevention or treatment interventions and reporting anxiety outcomes for new/expectant fathers in the perinatal mental health period were included. Our review follows the PRISMA reporting guidelines. One reviewer independently screened 5170 titles/abstracts; second reviewers screened 50%. Two reviewers independently screened full text, extracted data, and conducted risk of bias assessments. Synthesis: Cochrane's collaboration tool 2 was used to assess quality. Primarily results are synthesised narratively, a post-hoc sub-group analysis was completed on four studies using the same outcome measure. Main results: Twelve of the 5170 studies fulfilled the inclusion criteria. Studies used psychoeducational or practical skills interventions. Interventions mostly involved couple-dyads and three studies assessed PPA as a primary outcome. Included interventions were prevention-based; no treatment interventions were found. Father-only interventions consistently reported a significant reduction of PPA. Conclusions: Systematic searching yielded no treatment interventions, highlighting a substantial gap in the evidence base. Within a limited and heterogenous sample, no studies targeted diagnosed PPA. Evidence suggested father-focused interventions may be effective in preventing PPA, regardless of the intervention delivery mode or intervention content. However, consistency between study design and options within the field are lacking compared to interventions available for mothers.
