Sleep is impaired in children with attention-deficit/hyperactivity disorder (ADHD). However, population-based examination of indicators of sleep insufficiency and bedtime irregularity is limited. This investigation examined associations between ADHD, weeknight sleep insufficiency, and bedtime irregularity in a nationally-representative child sample, and indicators of these sleep outcomes in ADHD. Parents of children aged 3–17 years with ADHD (n = 7671) were surveyed through the 2020–2021 National Survey of Children's Health. Inverse probability of treatment weighting generated a weighted matched control sample (n = 51,572). Weighted generalized linear models were performed without and with age-stratification to examine associations between ADHD and sleep, adjusting for sociodemographics in the full sample, and between nineteen sociodemographic and clinical variables and sleep in ADHD. Having ADHD was associated with increased odds of sleep insufficiency and bedtime irregularity relative to controls, even after adjusting for sociodemographic variables. In ADHD, older age was associated with lower sleep insufficiency and greater bedtime irregularity. Black race, increased poverty, higher ADHD severity, depression, and increased screen time were associated with greater sleep insufficiency and bedtime irregularity. Adverse childhood experiences (ACEs) were associated with greater sleep insufficiency. Behavioral/conduct problems, female sex, and absence of both ADHD medication use and ASD diagnosis were associated with poorer bedtime irregularity. Age-stratified results are reported in text. Children with ADHD face heightened risk for insufficient sleep and irregular bedtimes. Findings suggest intervention targets (e.g., Black race, poverty, depression, screen time) to improve both sleep insufficiency and bedtime irregularity. Results highlight ACEs and behavioral/conduct problems as targets to improve sleep insufficiency and bedtime regularity, respectively. Age-stratified findings are discussed. • ADHD was associated with greater sleep insufficiency and bedtime irregularity relative to healthy controls in children. • In ADHD, Black race, poverty, ADHD severity, depression, and screentime indicated sleep insufficiency and bedtime irregularity. • ACEs were associated with sleep insufficiency. Female sex, behavioral or conduct problems were associated with bedtime irregularity. • Interventions addressing sociodemographic context, psychiatric symptoms, and screen use may improve sleep in child ADHD. • Additional age-stratified findings are discussed.

Background: This study used functional near-infrared spectroscopy (fNIRS) to investigate brain activation patterns in children with attention deficit hyperactivity disorder (ADHD) with and without additional comorbidities to identify disease-related biomarkers by the neuroimaging that will facilitate to make a diagnosis decision. Methods: In this study, 165 medication-naive children aged 7 to 15 years were recruited and categorized into four groups: ADHD, ADHD with learning disabilities (ADHD&LD), ADHD with oppositional defiant disorder (ADHD&ODD), and healthy controls. A multichannel fNIRS system was used to monitor hemodynamic changes at rest state in the prefrontal and temporal lobes of the brain. The amplitude of a low-frequency fluctuation (ALFF) matrix was calculated by summation and averaging of the square root of the signal power spectrum. One-way analysis of variance was used to identify statistical differences between channels. Results: All ADHD children presented significantly higher ALFF values in different brain regions when compared with the healthy controls. Patients with ADHD&LD exhibited higher ALFF values in the medial prefrontal cortex (PCh38 =.01, PCh48 =.01), temporal cortex (PCh22 =.04, PCh41 =.002, PCh51 =.001), and the left ventrolateral prefrontal cortex (PCh39 =.0009, PCh50 =.001), whereas ADHD&ODD children were not significantly different to those diagnosed with ADHD. Conclusions: ADHD with learning disabilities (LD) possessed a different pathogenesis from ADHD, manifested as lower functional brain activity in the medial prefrontal cortex, temporal cortex, and the left ventrolateral prefrontal cortex, while ADHD&ODD did not present significant changes compared with ADHD. ODD-related symptoms may be part of ADHD symptoms rather than being an independent disorder. [ABSTRACT FROM AUTHOR]

Oppositional defiant disorder (ODD) and attention-deficit/hyperactivity disorder (ADHD) are two of the most common childhood mental disorders, and they have substantial comorbidity. The developmental precursor model has long been widely used to explain the mechanisms of comorbidity between ODD and ADHD, however whether it is equally effective at the symptomatic level is unclear. Therefore, this study aimed to (a) examine the stability of the ODD and ADHD comorbidity network in a longitudinal sample of high-risk children in China; and (b) examine the longitudinal relationship between the ODD and ADHD symptom networks based on a developmental precursor model. Two hundred sixty-three Chinese children aged 6 to 13 years with ODD and/or ADHD were assessed for symptoms of ODD and ADHD in two surveys conducted 1 year apart. We used data from these two time points to construct two cross-sectional networks and a cross-lagged panel network (CLPN) to explore the symptom network for comorbidity of ODD and ADHD. The analysis shows that: (1) the two cross-sectional networks are highly similar in terms of structure, existence of edges, centrality estimates, and the invariance test shows that there is no significant difference between them. The symptoms "follow through", "interrupts/intrudes", "difficulty playing quietly" and "concentration" had the highest expected influence centrality at both time points. (2) Combined with the results of the cross-sectional and cross-lagged networks, we found that "annoy" and "blame" are potential bridge symptoms between the ODD and ADHD symptom networks. The symptom "annoy" forms a reciprocal predictive relationship with "interrupts/intrudes", while "blame" unidirectionally predicts "close attention". In addition, we found that "vindictive" predicted numerous ADHD symptoms, whereas "angry" was predicted by numerous ADHD symptoms. The findings emphasize the broad predictive relationship between ODD and ADHD symptoms with each other, and that ODD symptoms may lead to activation of the ADHD symptom network and vice versa. These findings suggest that the developmental precursor model at the symptom level may partially explain the comorbidity mechanisms of ODD and ADHD, and future studies should further investigate the underlying multiple mechanisms.

Background: Executive function is a high‐level set of cognitive processes related to goal‐directed behaviors including two conceptual subtypes of hot (emotional) and cold (cognitive) executive function (to abbreviate EF). EF deficits in attention deficit hyperactivity disorder (ADHD) leads to significant social impairments in the home, school, and community. Today the type and the extent of executive function defects in ADHD are still debated in studies. We aimed to evaluate hot and cold executive function among medication‐naive children with ADHD, with and without oppositional defiant disorder (ODD). Methods: Forty‐five children including suffering ADHD with ODD (n = 15), without ODD (n = 15), or typically developed (TD, n = 15) participated in this cross‐sectional study (the age of children was between 7 and 12 years old). The Child Symptom Inventory‐4 (CSI‐4) was used to screen behavioral and emotional symptoms. Wechsler Adult Intelligence Scale‐Revised‐Digit Span Task (WAIS‐R‐DST), Corsi Block Task (CBT), and Wisconsin Card Sorting Test (WCST) were used for assessing cold executive function. Assessing hot executive function was done with Delay Discounting Task (DDT) and Iowa Gambling Task (IGT). Results: Evaluating the cold executive function, total WAIS‐R‐DST score, Backward DST, total CBT score, and Backward CBT were significantly lower among ADHD than TD groups (p < 0.05). Assessing the hot executive function showed that the score of DDT and IGT was significantly lower among ADHD than TD groups (p < 0.05). Conclusion: Both hot and cold executive functions are defective in children with ADHD, while the comorbid of ODD has no significant effect. We suggest the clinicians to consider cognitive rehabilitation interventions as a necessary treatment modality for ADHD patients. [ABSTRACT FROM AUTHOR]

Various models of the dimensionality of behaviors associated with Oppositional Defiant Disorder (ODD) have been proposed or reported. Many of these models describe ODD-related behaviors in either two- or three-factor models. The purpose of the study was to determine which of the models of ODD-related behaviors demonstrated the best fit using teacher report of 15,521 children across eight grade levels and to examine measurement invariance of the model across grades. Confirmatory factor analyses were conducted to determine which of the models demonstrated best fit of teacher-reported ODD-related behaviors across eight grades. A two-factor model from a preliminary analysis of a subset of the current data demonstrated a better model fit than any of the existing six models examined and demonstrated measurement invariance across all grades. Across all of the models, affective and behavioral symptoms loaded onto separate factors, which may be an important consideration to inform future clinical and empirical work. [ABSTRACT FROM AUTHOR]

Objective: The purpose of this study was to examine the associations of ADHD and ODD symptoms in adolescence with occupational outcomes and incomes in adulthood within the Northern Finland Birth Cohort 1986 (NFBC1986). Method: ADHD symptoms were evaluated at ages 15 to 16 years using the Strengths and Weaknesses of ADHD symptoms and Normal Behaviors (SWAN) scale. ODD symptoms were assessed using a 7-point scale, like the SWAN assessment. Results: Symptoms of ADHD and ADHD + ODD were associated with elevated rates of unemployment, increased sick days, and lower annual incomes compared to controls for both sexes. Symptoms of ODD were associated with higher unemployment and more sick days for males, although these associations did not reach statistical significance in their association with annual incomes. Conclusion: Symptoms of ADHD were associated with adverse occupational outcomes and lower incomes. Furthermore, symptoms of ODD were associated with occupational outcomes but not with incomes.

Purpose: The primary objective of this study was to evaluate the effectiveness of the Coping Abilities Workshop, a structured intervention designed to enhance selfregulation, improve social performance, and reduce aggression among first to third-grade primary school students exhibiting signs of Oppositional Defiant Disorder in Tehran, District 2. Methodology: This randomized controlled trial involved 60 students, evenly divided into an intervention and a control group. Each group comprised 30 participants, and the intervention spanned eight weeks, with follow-up assessments conducted three months post-intervention. Measurements for selfregulation, social performance, and aggression were taken using standardized tools at three time points: pre-intervention, post-intervention, and follow-up. The data were analyzed using ANOVA with repeated measures and Bonferroni posthoc tests, utilizing SPSS software version 27. Findings: Significant improvements were observed in the intervention group compared to the control. Post-intervention results showed substantial increases in self-regulation (mean pre = 32.45, SD = 4.12; mean post = 45.67, SD = 3.56) and social performance (mean pre = 28.54, SD = 2.95; mean post = 40.26, SD = 2.45), along with a notable reduction in aggression (mean pre = 35.60, SD = 5.12; mean post = 20.22, SD = 4.75). These effects were maintained at the three-month followup, indicating the lasting impact of the intervention. Conclusion: The Coping Abilities Workshop significantly enhanced selfregulation and social performance while effectively reducing aggression among primary school students with Oppositional Defiant Disorder. The intervention proved to have a sustainable impact, suggesting its potential for broader application in similar educational and behavioral settings. [ABSTRACT FROM AUTHOR]

This study aimed to compare the effect of modified behavioral¬ therapy, parent-child interaction therapy (PCIT) and therapy based on mother and child's mentalization on the improvement of symptoms of the oppositional defiant disorder (ODD) in Zanjan preschool children. The framework of this research has a quasi-experimental multivariate design with pre-test and post-test. The population of this study included all children (girls and boys) aged 5-7 years who lived in Zanjan province in 1399 and received a diagnosis of ODD. From the children referred to the clinic, 75 samples were selected by available sampling method and randomly replaced in three equal groups (25 participants for each group). In this study, Child Symptom Inventory (1997) was used. Paired t-test results showed that all three methods were effective in reducing the symptoms of the disorder (p≤. 05). The results of Covariance analysis and Bonferroni post hoc test showed that there was a difference between the three treatments in reducing the symptoms of ODD (p≤. 05). The Comparison of experimental groups showed that the difference between the means of the modified behavioral therapy group with parent-child interaction therapy (1.07 *) and the therapy based on mother and child's mentalization (1.64 *) was significant (P

Background and Objectives: The aim of this study was to investigating of effectiveness of mindfulness-based parenting on mother's parenting stress in children with oppositional defiant disorder in primary school students. Materials and Methods: This experimental study was conducted with a pretest-posttest design with control group. In this research, the statistical population of the present study was all mothers with children with oppositional defiant disorder in Tehran city during the academic year of 2022-2023. First, 30 people were selected by randomly selected into two experimental and control groups were replaced (15 experimental people and 15 control people). In this study, for people experimental group was implemented in parenting based on mindfulness, but the control group received no training and remained in the waiting list. The instruments used in this study include oppositional defiant disorder rating scale (ODDRS) of Hommersen and et al (2006) and parenting stress index–short form (PSI-SF) of Abidin and et al (2006). Data analysis was performed using SPSS-24 software in two sections: descriptive (mean and standard deviation) and inferential (analysis of covariance). Results: Results indicated that mindfulness-based parenting significantly improvement on parenting stress in mothers and oppositional defiant disorder (P

Background: Interparental aggression is believed to increase the risk of behavioral disorders in offspring, and offspring behavioral problems may forecast interparental aggression. However, these assumptions have yet to be put to a strong test. This study, therefore, examined whether increased interparental aggression predicted increased symptoms of oppositional defiant disorder (ODD) and conduct disorder (CD) from preschool to adolescence and vice versa. Methods: A sample (n = 1,077; 49.6% girls) from two birth cohorts of children in Trondheim, Norway, was assessed biennially from age 4 to 16. Children's symptoms of ODD and CD were assessed using semi‐structured clinical interviews of parents (from age 4) and children (from age 8). One of the parents reported on their own and their partner's verbal and physical aggression. A random intercept cross‐lagged model was estimated to test the within‐family relations between interparental aggression, CD, and ODD symptoms. Results: Across development, increased interparental aggression predicted increased CD symptoms 2 years later, whereas an increased number of ODD symptoms forecasted increased interparental aggression. Conclusions: The argumentative/defiant, aggressive, and vindictive behaviors seen in ODD are often directed toward parents and may take a toll on their relationship and possibly foster interparental aggression, whereas aggression between parents may promote symptoms of CD in their offspring, which commonly extend beyond the home. Incorporating effective and non‐aggressive means to solve interparental conflict into parental management programs may reduce the development of symptoms of CDs in children. [ABSTRACT FROM AUTHOR]

Disruptive behavior disorders in children and adolescents are among the important disorders in the field of child and adolescent psychopathology, especially since they are known for their ability to stabilize and develop, forming more severe patterns in terms of symptoms and impact on the individual and society. Accordingly, this research paper aims to identify these disorders by clarifying their forms and clinical characteristics, while highlighting the factors that contribute to their emergence according to the explanatory mechanisms of attachment theory based on its basic principles and concepts, while clarifying the relationship of attachment patterns and the emergence of these disorders.

Attention deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) are highly comorbid. Many prior investigations have found that ADHD relates to anatomical abnormalities in gray matter. The abnormal gray matter of ADHD comorbid ODD is still poorly understood. This study aimed to explore the effect of comorbid ODD on gray matter volume (GMV) and functional alterations in ADHD. All data were provided by the ADHD‐200 Preprocessed Repository, including 27 ADHD‐only children, 27 ADHD + ODD children, and 27 healthy controls aged 9–14 years. Voxel‐based morphometry (VBM) and functional connectivity (FC) of resting‐state functional magnetic resonance imaging (fMRI) were used to compare the difference in GMV and FC between ADHD + ODD, ADHD‐only, and healthy children. The results showed that ADHD children with comorbid ODD had a more significant reduction in cerebellar volume, mainly in the anterior regions of the cerebellum (Cerebellum_4_5). The Cerebellum_4_5 showed increased functional connectivity with multiple cortical regions. These brain regions include numerous executive functioning (EF) and brain default mode network (DMN) nodes. The GMV abnormalities and excessive connectivity between brain regions may further exacerbate the emotional and cognitive deficits associated with ADHD. [ABSTRACT FROM AUTHOR]

Circadian preference, describes biological and behavioural characteristics that influence the ability to plan daily activities according to optimal waking times. It is divided into three main categories: morning, evening and intermediate. In particular, the evening chronotype is associated with conditions such as Attention Deficit Hyperactivity Disorder (ADHD) and Post Traumatic Stress Disorder (PTSD). This study was conducted in three groups aged 14–18 years: The first group consisted of 34 adolescents diagnosed with ADHD who had been in institutional care for at least two years and had not used medication in the last six months. The second group included 29 adolescents with ADHD living with their families who had not used medication in the last six months. The third control group consisted of 32 healthy adolescents. The study utilized sociodemographic data forms, the Turgay DSM-IV Disruptive Behavior Disorders Rating Scale (T-DSM-IV-S) to measure ADHD symptoms, the Childhood Chronotype Questionnaire (CCQ), and the Childhood Trauma Questionnaire (CTQ). In institutionalized adolescents with diagnosed ADHD, ADHD and disruptive behavior symptoms were more severe. Increased trauma scores were associated with higher ADHD and disruptive behaviour symptom severity and evening chronotype. In the conducted mediation analysis, evening chronotype was identified as a full mediator in the relationship between trauma symptoms and ADHD symptoms, while it was determined as a partial mediator in the relationship between trauma symptoms and PTSD symptoms. In conclusion, traumatic experiences in institutionalized adolescents with diagnosed ADHD may exacerbate ADHD and disruptive behavior symptoms. Evening chronotype is associated with ADHD and disruptive behavior symptoms, and therefore, the chronotypes of these adolescents should be assessed. Chronotherapeutic interventions may assist in reducing inattention, hyperactivity, and behavioral problems. [ABSTRACT FROM AUTHOR]

Children with Disruptive Mood Dysregulation Disorder (DMDD) or Oppositional Defiant Disorder (ODD) are characterized by irritability and social difficulties. However, the mechanisms underlying these disorders could be different. This study explores differences in social cognition and executive function (EF) across DMDD and ODD and the influence of these factors and their interaction on social problems in both groups. Children with DMDD (n = 53, Mage = 9.3) or ODD (n = 39, Mage = 9.6) completed neuropsychological tasks measuring social cognition (Theory of Mind and Face-Emotion Recognition) and EF (cognitive flexibility, inhibition, and working memory). Parents reported social problems. More than one-third of the children with DMDD and almost two-thirds of those with ODD showed clear difficulties with Theory of Mind. Most children with DMDD (51–64%) or ODD (67–83%) showed difficulties with EF. In children with DMDD, worse EF (β = –.36) was associated with more social problems, whereas in children with ODD, better EF (β =.44) was associated with more social problems. In those with ODD, but not in those with DMDD, the interaction between social cognition and EF contributed to the explained variance of social problems (β = –1.97). Based on the observed interaction pattern, enhanced EF may lead to increased social problems among children with ODD who also exhibit social cognition difficulties. This study suggests the existence of distinct neuropsychological mechanisms underlying the social issues observed in children with DMDD versus those with ODD. [ABSTRACT FROM AUTHOR]

Interpersonal neural synchrony (INS) between mothers and children responds to the temporal similarity of brain signals in joint behavior between dyadic partners and is considered an important neural indicator of the formation of adaptive social interaction bonds. Parent-child interactions are particularly important for the development and maintenance of oppositional defiant disorder (ODD) in children, but the underlying neurocognitive mechanisms are unknown. Therefore, in the current study we measured INS between mothers and children in interactions by using simultaneous functional Near-infrared Spectroscopy (fNIRS), and explored its association with ODD symptoms in children. Seventy-two mother-child dyads were recruited to participate in the study, including 35 children with ODD and 37 healthy children to be used as a control. Each mother-child dyad was measured for neural activity in frontal, parietal, and temporal lobe regions while completing free-play as well as positive, and negative topic discussion tasks. We used Phase-locked value to calculate the synchrony strength and then used the K-means algorithm and k-space based alignment tests to confirm the specific patterns of parent-child synchrony in different brain areas. The results showed that, in free-play (right MFG and bilateral SFG), positive (left TPJ and bilateral SFGdor), and negative (bilateral SFGmed, right ANG, and left MFG) topic discussions, the mother-child pairs showed different patterns of INS. These specific INS patterns were significantly lower in the ODD group compared to the control group and were negatively associated with ODD symptoms in children. Network analyses showed that these INS patterns were connected to different nodes in the ODD symptom network. Our findings suggest that ODD mother-child dyads exhibit lower neural synchrony across a wide range of parent-child interactions. Neural synchrony in the context of interpersonal interactions provides new insights into understanding the neural mechanisms of ODD and can be used as an indicator of neural and socio-environmental factors in the network of psychological disorder symptoms.

This paper by Nobakht, Steinsbekk & Wichstrom (2023) is a model of good science in the study of oppositional defiant disorder and conduct disorder. Their approach illustrates a thoughtful research design, statistical modeling sufficient to empirically evaluate developmental processes, and a full consideration of the theoretical implications of their work. This contrasts with a broad history of research on ODD and CD that far too often has only reified biased assumptions about these phenomena rather than rigorously scrutinizing them. Their demonstration of a unidirectional developmental flow of influence from ODD to interparental aggression, and thence to CD highlights a set of complicated developmental processes involving these disorders and their environment. It expands on evidence of the toll that ODD exerts on parents and provides guidance for more specific intervention. Standards in developmental psychopathology research should include testing bidirectional processes and employing designs that could falsify rather than reify existing beliefs. Examining key mechanisms in such processes will more rapidly generate improvements in assessment and treatment. [ABSTRACT FROM AUTHOR]

BackgroundCross-sectional studies have demonstrated associations between screen time and disruptive behavior disorders (conduct disorder and oppositional defiant disorder); however, prospective associations remain unknown. This study's objective was to determine the prospective associations of contemporary screen time modalities with conduct and oppositional defiant disorder in a national cohort of 9-11-year-old children.MethodsWe analyzed data from the Adolescent Brain Cognitive Development (ABCD) Study (N = 11,875). Modified Poisson regression analyses were conducted to estimate the associations between baseline child-reported screen time (total and by modality) and parent-reported conduct or oppositional defiant disorder based on the Kiddie Schedule for Affective Disorders and Schizophrenia (KSADS-5) at 1-year follow-up, adjusting for potential confounders.ResultsParticipants reported an average of 4 hr of total screen time per day at baseline. Each hour of total screen time per day was prospectively associated with a 7% higher prevalence of conduct disorder (95% CI 1.03-1.11) and a 5% higher prevalence of oppositional defiant disorder (95% CI 1.03-1.08) at 1-year follow-up. Each hour of social media per day was associated with a 62% higher prevalence of conduct disorder (95% CI 1.39-1.87). Each hour of video chat (prevalence ratio [PR] 1.21, 95% CI 1.06-1.37), texting (PR 1.19, 95% CI 1.07-1.33), television/movies (PR 1.17, 95% CI 1.10-1.25), and video games (PR 1.14, 95% CI 1.07-1.21) per day was associated with a higher prevalence of the oppositional defiant disorder. When examining thresholds, exposure to >4 hr of total screen time per day was associated with a higher prevalence of conduct disorder (69%) and oppositional defiant disorder (46%).ConclusionsHigher screen time was prospectively associated with a higher prevalence of new-onset disruptive behavior disorders. The strongest association was between social media and conduct disorder, indicating that future research and interventions may focus on social media platforms to prevent conduct disorder.

A strong link between children's emotion regulation and oppositional defiant disorder (ODD) symptoms has been documented; however, the within-person mechanisms remain unclear. Based on the self-control theory and self-regulation theory, our study investigated the longitudinal, bidirectional relationship between emotion regulation and ODD symptoms in school-age children with ODD using parent- and teacher-reported data, respectively. A total of 256 Chinese elementary school students participated in a three-wave longitudinal study spanning two years. We used the random intercept cross-lagged panel model (RI-CLPM) to investigate the concurrent and longitudinal associations between emotion regulation and ODD symptoms. Results from the RI-CLPMs revealed that ODD symptoms were negatively correlated with emotion regulation and positively correlated with emotion lability/negativity at both the between-person and within-person levels across settings. Additionally, in the school setting, emotion regulation negatively predicted subsequent ODD symptoms but not vice versa, whereas emotion lability/negativity was bidirectionally associated with ODD symptoms over time. The longitudinal associations of ODD symptoms with emotion regulation and lability/negativity were not observed in the home setting. These findings suggest a circular mechanism between children's emotion regulation and ODD symptoms and support the view that emotion regulation, particularly emotion lability/negativity, plays an important role in the development of ODD symptoms.

Oppositional defiant disorder (ODD) is one of the most prevalent childhood mental health disorders and is extremely affected by family factors. However, limited studies have addressed the issue from the perspective of family systems. The current study examines the associations between multilevel family factors (i.e., family cohesion/ adaptability at system level, mother-child and father-child attachment at a dyadic level, and child self-esteem at an individual level) and emotional and behavioral problems among children with ODD in China. The participants were 256 Chinese children with ODD and their parents and class master teachers. A multiple-informant approach and structural equation model were used. The results revealed that system level factors (family cohesion/adaptability) were associated with child emotional and behavior problems indirectly through factors at the dyadic level (mother-child attachment) and the individual level (child self-esteem) in sequence. Mother-child, but not father-child, attachment, mediated the linkage between family cohesion/adaptability and the emotional problems of children with ODD. Moreover, child self-esteem mediated the association between mother-child attachment and child emotional and behavioral problems. The findings of the present study underscored that multilevel family factors are uniquely related to emotional and behavioral problems in children with ODD.

Abstract Background Conduct disorders (CD) are among the most frequent psychiatric disorders in children and adolescents, with an estimated worldwide prevalence in the community of 2–4%. Evidence-based psychological outpatient treatment leads to significant improvement in about two-thirds of cases. However, there seems to be considerable variation in rates of CD diagnoses and implementation of evidence-based interventions between nations. The aim of this study was to compare administrative prevalence and treatment patterns for CD in children and adolescents seen in health care systems across four Western countries (Denmark, Germany, Norway, and the USA). Methods Cross-sectional observational study using healthcare data to identify children and adolescents (aged 0–19 years) with an ICD-10 code for CD within the calendar year 2018. Within each country’s study population, the prevalence of CD, psychiatric comorbidity, psychopharmacological treatment, and psychiatric hospitalisation was calculated. Results The prevalence of diagnosed CD differed 31-fold between countries: 0.1% (Denmark), 0.3% (Norway), 1.1% (USA) and 3.1% (Germany), with a male/female ratio of 2.0–2.5:1. The rate of psychiatric comorbidity ranged from 69.7 to 86.1%, with attention-deficit/hyperactivity disorder being most common. Between 4.0% (Germany) and 12.2% (USA) of youths with a CD diagnosis were prescribed antipsychotic medication, and 1.2% (Norway) to 12.5% (Germany) underwent psychiatric hospitalisation. Conclusion Recognition and characteristics of youths diagnosed with CD varied greatly by country. In some countries, the administrative prevalence of diagnosed CD was markedly lower than the average estimated worldwide prevalence. This variation might reflect country-specific differences in CD prevalence, referral thresholds for mental health care, diagnostic tradition, and international variation in service organisation, CD recognition, and availability of treatment offers for youths with CD. The rather high rates of antipsychotic prescription and hospitalisation in some countries are remarkable, due to the lack of evidence for these therapeutic approaches. These findings stress the need of prioritising evidence-based treatment options in CD. Future research should focus on possible reasons for inter-country variation in recognition and management of CD, and also address possible differences in patient-level outcomes.

An important goal of clinical/developmental research is to identify factors contributing to the onset and maintenance of psychopathology – particularly factors that could be modified through intervention. Large‐scale, multi‐informant, longitudinal studies provide valuable opportunities for testing such etiological hypotheses, as illustrated by Nobakht et al.'s recent six‐wave cohort study spanning ages 4–14. At a within‐person level, emotion regulation (ER) deficits consistently predicted oppositional defiant disorder (ODD) symptoms (including both irritability and defiance), whereas victimization did not. These results comport with growing evidence highlighting ER's centrality to ODD and psychopathology more broadly. While the ER findings carry promising implications, caution is warranted in interpreting the results for victimization given that its association with psychopathology is well‐documented. More research is needed to test precise questions about within‐ and between‐person processes involving ER, victimization, and psychopathology across development. Pressing research questions include whether, how, and when youths' ER can be modified, and with what effects on clinical outcomes. [ABSTRACT FROM AUTHOR]

Background: Childhood oppositional defiant disorder (ODD) is associated with adverse outcomes which can continue to impair life well into adulthood. Identifying modifiable etiological factors of ODD is therefore essential. Although bullying victimization and poor emotion regulation are assumed to be risk factors for the development of ODD symptoms, little research has been conducted to test this possibility. Methods: A sample (n = 1,042) from two birth cohorts of children in the city of Trondheim, Norway, was assessed biennially from age 4 to 14 years. Parents and children (from age 8) were assessed with clinical interviews to determine symptoms of ODD, children reported on their victimization from bullying, and teachers reported on children's emotion regulation. Results: Oppositional defiant disorder symptoms increased from age 4 to 6, from age 8 to 10, and then started to wane as children entered adolescence. A Random Intercept Cross‐Lagged Panel Model revealed that increased emotion regulation predicted a reduced number of ODD symptoms across development (β = −.15 to −.13, p <.001). This prediction was equally strong for the angry/irritable and argumentative/defiant dimensions of ODD. No longitudinal links were observed between bullying victimization and ODD symptoms. Conclusions: Improving emotion regulation skills may protect against ODD symptoms throughout childhood and adolescence. [ABSTRACT FROM AUTHOR]

Objective: This study is to investigate the relationship of parental anger expression and symptoms in children with oppositional defiant disorder (ODD). Methods: Forty-six children with ODD and 46 age-gendermatched normal children participated. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), guided the diagnoses. Parental anger expression and children's anger management were assessed using the State-Trait Anger Expression Inventory-2 and Children Emotion Management Scales. Results: ODD symptoms were directly predicted by maternal anger index (AI) (β = 0. 13, P<0.05) and anger expression-out(AX-O) (β = 0. 25, P <0.05). Children's anger cope (AC) played a mediating function to maternal AI through ODD symptoms, occupying 13% of the total effect; their AC and anger dysregulation (AD) played a mediating function to maternal AX-Othrough ODD symptoms, accounting for 29% and 18% of the total effect, respectively. Conclusion: It suggests that anger cope and anger dysregulation in children with oppositional defiant disordermay may play a mediating role between maternal anger expression and oppositional defiant disorder symptoms.

Objective: The purpose of this research was to compare the effectiveness of the coping power training program and the Long and Forehand parenting program on the aggression of students with oppositional defiant disorder. Methods: A qualitative approach was employed in this study, utilizing the grounded theory method. The statistical population of first to third grade students with symptoms of oppositional defiant disorder and their mothers in two cities of Tehran in 2022. A total of 45 sample people were selected in a non-random, purposeful way and randomly arranged in one of three groups of 15 people, the coping power program, the Long and Forehand parenting program, and the control group, and they answered Shahim's aggression questionnaire. Before the implementation of the training course, a pre-test was conducted for all three groups, and after it was completed, a post-test was conducted for all three groups. The resulting data were analyzed using SPSS statistical software and the method of variance analysis with repeated measurements. Results: Based on the results of the effectiveness of both training programs, it has had a significant impact on aggression, and the effect of long and forehand parenting program training on aggression has been greater than that of coping power program. Conclusions: Therefore, it can be concluded that the coping power program and the Long and Forehand parenting program can be used as a suitable therapeutic intervention tool to reduce the aggression of students with oppositional defiant disorder.

Background: Attention-Deficit/Hyperactivity Disorder (ADHD) affects 5% of children and 2.5% of adults worldwide. Comorbidities are frequent, and Oppositional Defiant Disorder (ODD) reaches 50%. Family environment is crucial for the severity of behaviors and for prognosis. In middle-income countries, access to treatment is challenging, with more untreated children than those under treatment. Face-to-face behavioral parent training (PT) is a well-established intervention to improve child behavior and parenting. Method: A clinical trial was designed to compare PT-online and face-to-face effects to a waiting list group. Outcomes were the ADHD and ODD symptoms, parental stress and styles, and quality of life. Families were allocated into three groups: standard treatment (ST), ST + PT online, and ST + Face-to-Face PT. We used repeated measures ANOVA for pre x post treatment analysis corrected for multiple comparisons. Results and discussion: Parent training was effective in reducing symptoms of ADHD (p = 0.030) and ODD (p = 0.026) irrespective of modality (p = 1.000). The combination of ST and PT was also associated with better quality of life in the physical domain for patients (p = 0.009) and their parents (p = 0.050). In addition to preliminary data, online intervention seems effective for parenting and improving social acceptance of children. The potential to reach many by an online strategy with a self-directed platform may imply effectiveness with a low cost for public health to support parents' symptoms management.

Low activity of the hypothalamic–pituitary–adrenal axis (HPAA) has been found in children with attention deficit hyperactivity disorder (ADHD). The condition may be related to the reduced attention regulation capacity and/or to comorbid oppositional defiant or conduct disorder (ODD/CD). Sex differences are probable but not sufficiently studied. We analyzed the HPAA activity and sympathetic nervous system reactivity (SR) in children with ADHD while accounting for ADHD symptom presentation, comorbidity, and sex differences. The sample comprised 205 children, 98 (61 boys, 37 girls) with ADHD and 107 (48 boys, 59 girls) healthy controls. DSM-5 phenotypic symptom presentation and comorbid ODD/CD were assessed using clinical interviews. Hair cortisol concentration (HCC) was used to assess the long-term, cumulative activity of the HPAA. SR was assessed via skin conductance response (SCR). For control purposes, comorbid internalizing symptoms and indicators of adverse childhood experiences (ACE) were assessed. Children were medication naive. Boys presenting with predominantly inattentive symptoms (ADHD-I) showed lower HCC than healthy boys. Girls presenting with combined symptoms (ADHD-C) showed higher HCC than did healthy girls (p's < 0.05, sex-by-group interaction, F (2,194) = 4.09, p = 0.018). Boys with ADHD plus ODD/CD showed a blunted SR (p < 0.001, sex-by-group interaction, F (2,172) = 3.08, p = 0.048). Adjustment for ACE indicators led to non-significant differences in HCC but did not affect differences in SR. HCC constitutes an easily assessable, reliable, and valid marker of phenotypic ADHD-related features (i.e. symptom presentation and comorbidity). It indicates more homogenous subgroups of ADHD and might point to specifically involved pathophysiological processes. [ABSTRACT FROM AUTHOR]

Objective: To investigate the characteristics of cortical morphology in children with attention deficit hyperactivity disorder (ADHD) and those with oppositional defiant disorder (ODD) from both categorical and dimensional analyses. Methods: A total of 72 children were enrolled, including 16 children with ADHD and ODD, 20 children with ADHD without ODD, and 36 age-gender-matched normal children. The diagnoses were made according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria. The Chinese Wechsler Intelligence Scale for Children (C-WISC) was used to access intelligence quotient. All subjects participated in the magnetic resonance imaging (MRI) scan. The features of cortical morphology were determined using FreeSurfer software. Results: Children with ADHD and ODD[ (6 528.1±857.5) mm³ vs. (7 591.2±657.3) mm³] and children with ADHD only[ (6 867.2±841.3) mm³ vs. (7 591.2±657.3) mm³] had smaller volume in the left lateral superior temporal gyrus (P ＜0.05) than controls. No difference was found between ADHD with ODD group and ADHD without ODD group. There was no correlation between the cortical volume of left lateral superior temporal gyrus and ODD symptoms. Conclusion: The reduced cortical volume of left lateral superior temporal gyrus may be an important indication of the abnormal brain structure of ADHD in children. And comorbid status of ODD dose not change this structural variation [ABSTRACT FROM AUTHOR]

Background: Conduct disorders (CD) are among the most frequent psychiatric disorders in children and adolescents, with an estimated worldwide prevalence in the community of 2–4%. Evidence-based psychological outpatient treatment leads to significant improvement in about two-thirds of cases. However, there seems to be considerable variation in rates of CD diagnoses and implementation of evidence-based interventions between nations. The aim of this study was to compare administrative prevalence and treatment patterns for CD in children and adolescents seen in health care systems across four Western countries (Denmark, Germany, Norway, and the USA). Methods: Cross-sectional observational study using healthcare data to identify children and adolescents (aged 0–19 years) with an ICD-10 code for CD within the calendar year 2018. Within each country's study population, the prevalence of CD, psychiatric comorbidity, psychopharmacological treatment, and psychiatric hospitalisation was calculated. Results: The prevalence of diagnosed CD differed 31-fold between countries: 0.1% (Denmark), 0.3% (Norway), 1.1% (USA) and 3.1% (Germany), with a male/female ratio of 2.0–2.5:1. The rate of psychiatric comorbidity ranged from 69.7 to 86.1%, with attention-deficit/hyperactivity disorder being most common. Between 4.0% (Germany) and 12.2% (USA) of youths with a CD diagnosis were prescribed antipsychotic medication, and 1.2% (Norway) to 12.5% (Germany) underwent psychiatric hospitalisation. Conclusion: Recognition and characteristics of youths diagnosed with CD varied greatly by country. In some countries, the administrative prevalence of diagnosed CD was markedly lower than the average estimated worldwide prevalence. This variation might reflect country-specific differences in CD prevalence, referral thresholds for mental health care, diagnostic tradition, and international variation in service organisation, CD recognition, and availability of treatment offers for youths with CD. The rather high rates of antipsychotic prescription and hospitalisation in some countries are remarkable, due to the lack of evidence for these therapeutic approaches. These findings stress the need of prioritising evidence-based treatment options in CD. Future research should focus on possible reasons for inter-country variation in recognition and management of CD, and also address possible differences in patient-level outcomes.

Background: Impulsivity is viewed as key to attention‐deficit/hyperactivity disorder (ADHD) and disruptive behavior disorders (DBD). Yet, to date, no work has provided an item‐level analysis in longitudinal samples across the critical developmental period from childhood into adolescence, despite prior work suggesting items exhibit differential relevance with respect to various types of impairment. The current study conducted a novel longitudinal network analysis of ADHD and oppositional defiant disorder (ODD) symptoms between childhood and adolescence, with the important applied prediction of social skills in adolescence. Methods: Participants were 310 children over‐recruited for clinical ADHD issues followed longitudinally for six years in total with gold standard diagnostic procedures and parent and teacher ratings of symptoms and social outcomes. Results: Findings from baseline, Year 3, and Year 6 suggested Difficulty waiting turn, Blurts, and Interrupts/intrudes were key bridge items across cross‐sectional and longitudinal parent‐reported DBD networks. Furthermore, shortened symptom lists incorporating these symptoms were stronger predictors of teacher‐rated social skills 5 years later compared to total DBD scores. Conclusions: Such findings are consistent with the trait impulsivity theory of DBD and ADHD and may inform useful screening tools and personalized intervention targets for children at risk for DBD during adolescence.

The assessment of oppositional defiant disorder, conduct disorder, antisocial personality disorder, and intermittent explosive disorder—the Disruptive, Impulse Control and Conduct Disorders—can be affected by biases in clinical judgment, including overestimating concerns about distinguishing symptoms from normative behavior and stigma associated with diagnosing antisocial behavior. Recent nosological changes call for special attention during assessment to symptom dimensions of limited prosocial emotions and chronic irritability. The present review summarizes best practices for evidence-based assessment of these disorders and discusses tools to identify their symptoms. Despite the focus on disruptive behavior disorders, their high degree of overlap with disruptive mood dysregulation disorder can complicate assessment. Thus, the latter disorder is also included for discussion here. Good practice in the assessment of disruptive behavior disorders involves using several means of information gathering (e.g., clinical interview, standardized rating scales or checklists), ideally via multiple informants (e.g., parent-, teacher-, and self-report). A commitment to providing a full and accurate diagnostic assessment, with careful and attentive reference to diagnostic guidelines, will mitigate concerns regarding biases. [ABSTRACT FROM AUTHOR]

Addressing current challenges in research on disruptive mood dysregulation disorder (DMDD), this study aims to compare executive function in children with DMDD, children with attention-deficit/hyperactivity disorder (ADHD), and children with oppositional defiant disorder (ODD). We also explore associations between irritability, a key DMDD characteristic, and executive function in a clinical sample regardless of diagnosis. Our sample include children (6–12 years) referred to child psychiatric clinics. Measures of daily-life (parent-reported questionnaire) and performance-based (neuropsychological tasks) executive function were applied. Identifying diagnoses, clinicians administered a standardized semi-structured diagnostic interview with parents. Irritability was assessed by parent-report. First, we compared executive function in DMDD (without ADHD/ODD), ADHD (without DMDD/ODD), ODD (without DMDD/ADHD) and DMDD + ADHD (without ODD). Second, we analyzed associations between executive function and irritability using the total sample. In daily life, children with DMDD showed clinically elevated and significantly worse emotion control scores compared to children with ADHD, and clinically elevated scores on cognitive flexibility compared to norm scores. Children with DMDD had significantly less working memory problems than those with ADHD. No differences were found between DMDD and ODD. Increased irritability was positively associated with emotional dyscontrol and cognitive inflexibility. For performance-based executive function, no diagnostic differences or associations with irritability were observed. We discuss how, in daily life, children with high irritability-levels get overwhelmed by feelings without accompanying regulatory capacities. [ABSTRACT FROM AUTHOR]
