The Association between ADHD Symptoms and Antisocial Behavior: Differential Effects of Maternal and Paternal Parenting Behaviors

The present study examined the moderating role of maternal and paternal behaviors on the association between ADHD symptoms and antisocial behavior. The data are from a Swedish community-based study with 2886 adolescent participants, aged 13–15. We analyzed the adolescents’ self-reports of negative and positive parental behavior, ADHD symptoms, and antisocial behavior. Results show that ADHD symptoms significantly predicted levels of antisocial behavior in both maternal- and paternal-moderated regression models. Also, several significant interaction effects emerged. Fathers’ attempted understanding and mothers’ warmth significantly buffered the association with antisocial behavior. In turn, mothers’ negative behaviors—both coldness and rejection and angry outbursts—significantly enhanced the association with antisocial behavior, whereas only fathers’ angry outbursts emerged as a significant moderator. Thus, there is support for differential effects of maternal and paternal behavior on the association between ADHD symptoms and adolescent antisocial behavior.

The Mediating Role of Emotion Regulation Strategies between Symptoms of Attention Deficit Hyperactivity Disorder and Anxiety-Depression Problems in Children

The purpose of this study was to investigate the mediating role of emotion regulation strategies of ADHD and anxiety-depression problems in children. Using a cross-sectional research design, this study collected a sample of children with ADHD and assessed their ADHD symptoms, anxiety-depression status, and emotion regulation strategies utilizing standardized tools. The data analysis results showed that emotion regulation strategies played a significant mediating role between ADHD symptoms and anxiety-depression problems, indicating that emotion regulation ability in children with ADHD may be an important factor affecting their anxiety and depression. This study not only provides a new perspective for understanding the emotional and behavioral problems of children with ADHD but also offers empirical evidence for developing targeted intervention measures. In the future, training in emotion regulation strategies is expected to become an important part of interventions for children with ADHD.

ADULT ADHD, SELF-EFFICACY, AND ACADEMIC PERFORMANCE IN LANGUAGE LEARNING: THE CASE OF FRESHMEN IN THE FACULTY OF ARTS AND HUMANITIES

The prevalence of ADHD in Morocco is still unknown. The paper sought to determine the extent to which this disorder may be prevalent in university students along with whether it would differ significantly among males and females. It also aimed to identify whether there would be a significant difference in both academic performance and self-efficacy among the ADHD and non-ADHD group. Three questionnaires were used to achieve this purpose. Cronbachs alpha was run followed by a chi-square test for independence and two independent-samples t-tests. There was no significant association between gender and ADHD symptoms (p = .12). In addition, there was no significant difference in academic performance (p = .39) and in self-efficacy scores (p = .46) for the ADHD and non-ADHD students. The study emphasized on the importance of a formal ADHD diagnosis as it could have provided insightful findings.

Treatments with versus without medication for children with behavioural difficulties in clinical practice: an economic evaluation with observational data.

Economic evaluations of treatments for children with behavioural difficulties (i.e., characteristics of attention-deficit/hyperactivity disorder (ADHD) and/or oppositional defiant disorder (ODD)) usually rely on data of randomised controlled trials or are model-based. Findings of such studies may not be representative of cost-effectiveness and cost-utility in clinical practice. The current longitudinal study aimed to perform an economic evaluation of treatments for children with hyperactivity, impulsive behaviours, inattention, and/or behavioural difficulties using observational data that were obtained in clinical practice. Parents of 209 children (aged 5-12) who were referred to 1 of 10 Dutch youth mental healthcare institutions and who received treatment with (n = 108) or without (n = 101) the use of medication, filled out questionnaires at three timepoints (baseline, and ~ 6 and ~12 months later). Propensity score matching was used to make both groups comparable. Outcomes included quality-adjusted life years (QALYs), ADHD and ODD symptom severity, and impairment. Costs were measured from a societal perspective. Incremental cost-effectiveness ratios (ICERs) were estimated, and cost-effectiveness acceptability curves (CEACs) were derived to show uncertainty around the ICER. Results did not show statistically significant differences in costs and effects between children who were treated with medication (alone or in combination with non-medication treatment) and those who were treated without medication. CEAC suggested that medication treatment has a 55% probability of being cost-effective at the €80,000 threshold and 36% at the €20,000 threshold compared with treatment without medication. Using observational data, our study did not provide clear evidence of the cost-effectiveness and cost-utility of treatment with medication compared with treatment without medication in clinical practice.

Comparative analysis of electroencephalogram (EEG) data gathered from the frontal region with other brain regions affected by attention deficit hyperactivity disorder (ADHD) through multiresolution analysis and machine learning techniques

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by repeated patterns of hyperactivity, impulsivity, and inattention that limit daily functioning and development. Electroencephalography (EEG) anomalies correspond to changes in brain connection and activity. The authors propose utilizing empirical mode decomposition (EMD) and discrete wavelet transform (DWT) for feature extraction and machine learning (ML) algorithms to categorize ADHD and control subjects. For this study, the authors considered freely accessible ADHD data obtained from the IEEE data site. Studies have demonstrated a range of EEG anomalies in ADHD patients, such as variations in power spectra, coherence patterns, and event-related potentials (ERPs). Some of the studies claimed that the brain’s prefrontal cortex and frontal regions collaborate in intricate networks, and disorders in either of them exacerbate the symptoms of ADHD. , Based on the research that claimed the brain’s prefrontal cortex and frontal regions collaborate in intricate networks, and disorders in either of them exacerbate the symptoms of ADHD, the proposed study examines the optimal position of EEG electrode for identifying ADHD and in addition to monitoring accuracy on frontal/ prefrontal and other regions of brain our study also investigates the position groupings that have the highest effect on accurateness in identification of ADHD. The results demonstrate that the dataset classified with AdaBoost provided values for accuracy, precision, specificity, sensitivity, and F1-score as 1.00, 0.70, 0.70, 0.75, and 0.71, respectively, whereas using random forest (RF) it is 0.98, 0.64, 0.60, 0.81, and 0.71, respectively, in detecting ADHD. After detailed analysis, it is observed that the most accurate results included all electrodes. The authors believe the processes can detect various neurodevelopmental problems in children utilizing EEG signals.

A Psychometric Evaluation of the Revised Version of the Adult ADHD Self-Report Scale in Chinese Adolescents.

Adolescent-specific ADHD self-report screening measures can greatly increase the likelihood of correct diagnosis and timely treatment of ADHD in adolescents. This study provides preliminary evidence for evaluating the reliability and validity of the Adult ADHD Self-Report Scale-Revised (ASRS-R) in a school-based sample of Chinese adolescents. The ASRS-R and the Strengths and Difficulties Questionnaire (SDQ) were administered to 867 adolescents aged 12 to 16 years (Mage = 13.08 years). Construct validity was assessed using correlation analysis of the ASRS-R with the SDQ. Moreover, confirmatory factor analysis (CFA), internal consistency, retest reliability, and measurement invariance of the scales were examined by gender. CFA showed a two-dimensional factor structure of the ASRS-R, and the model fitted the data well (χ2/df = 4.370, RMSEA = 0.062, TLI = 0.932, CFI = 0.940, GFI = 0.927, AGFI = 0.907, and SRMR = 0.038). The ASRS-R scale was invariant across gender and had satisfactory internal consistency (Cronbach's alpha = .934) and test-retest reliability (intraclass correlation coefficient = .874). The construct validity, as calculated using the SDQ, was also acceptable. The ASRS-R can be a psychometrically reliable self-report instrument and provide preliminary support as a simple tool for identifying ADHD symptoms in Chinese adolescents. The findings provide evidence for extending the application of the ASRS, previously limited to adults, to the adolescent populations.

Perceptions of Academic Performance, Impairment, and Mental Health in University Students With and Without ADHD

Objective: This study aims to investigate the impact of positive illusory bias (PIB) on the relationship between ADHD symptoms and functioning in college students, with a focus on gender differences. Method: The sample consisted of 195 college students, including 148 with ADHD and 47 without ADHD. Measures of ADHD symptomatology, life satisfaction, affect, gender identity, and impairment were collected, along with cumulative grade point average. Results: ADHD symptomatology was inversely linked to subjective well-being, with PIB acting as a significant moderator. Functional impairment was predicted by ADHD symptoms and subjective well-being, while social impairment and academic functioning were predicted by PIB and well-being. Significant gender differences were found, particularly in the interaction between PIB and ADHD symptoms for non-binary individuals. Conclusion: This study suggests that PIB is relevant for emerging adults with ADHD enrolled in higher education. Subjective well-being and PIB act as buffers against the detrimental functional and social effects of ADHD symptoms in emerging adult college students. The study highlights the importance of considering gender-specific approaches in understanding and supporting the mental health of this population.

Emotional Dysregulation in Emerging Adult ADHD: A Key Consideration in Explaining and Classifying Impairment and Co-Occurring Internalizing Problems

Objective: The current study sought to clarify and harness the incremental validity of emotional dysregulation and unawareness (EDU) in emerging adulthood, beyond ADHD symptoms and with respect to concurrent classification of impairment and co-occurring problems, using machine learning techniques. Method: Participants were 1,539 college students (Mage = 19.5, 69% female) with self-reported ADHD diagnoses from a multisite study who completed questionnaires assessing ADHD symptoms, EDU, and co-occurring problems. Results: Random forest analyses suggested EDU dimensions significantly improved model performance (ps < .001) in classifying participants with impairment and internalizing problems versus those without, with the resulting ADHD + EDU classification model demonstrating acceptable to excellent performance (except in classification of Work Impairment) in a distinct sample. Variable importance analyses suggested inattention sum scores and the Limited Access to Emotional Regulation Strategies EDU dimension as the most important features for facilitating model classification. Conclusion: Results provided support for EDU as a key deficit in those with ADHD that, when present, helps explain ADHD’s co-occurrence with impairment and internalizing problems. Continued application of machine learning techniques may facilitate actuarial classification of ADHD-related outcomes while also incorporating multiple measures.

Attention-Deficit/Hyperactivity Disorder and Subsequent Trauma Exposure: The Mediating Role of Deviant Peer Affiliation.

Individuals with ADHD symptoms are at an increased risk of lifetime trauma exposure. However, research has yet to fully examine whether symptoms of ADHD function as a temporal risk factor for experiencing trauma and specific mechanisms that may explain the association between symptoms of ADHD and trauma exposure. Two constructs that may account for the relation between ADHD symptoms and trauma are deviant peer association and neighborhood disadvantage. The present study sought to 1) elucidate the temporal nature of ADHD symptoms and exposure to trauma and 2) examine whether peer deviancy and/or neighborhood disadvantage mediate the relation between childhood ADHD symptoms and subsequent trauma exposure across a 20-year longitudinal cohort study. Participants (N = 616) were predominantly Black/African American (86%; Male n = 389) from an urban school district. Using structural equation modeling, total trauma exposures during young adulthood (Years 17-20) were regressed on parent- and teacher-rated ADHD symptoms in Grade 1 (Year 1). A significant indirect path from ADHD symptoms to trauma exposure through deviant peer affiliation (Year 16) indicated that having childhood ADHD symptoms predicted deviant peer affiliation 16years later, which in turn predicted greater exposures to traumatic events during young adulthood, controlling for neighborhood disadvantage. Neighborhood disadvantage was not a significant mediator when accounting for peer deviancy. Taken together, findings contribute to a limited body of research that utilizes a prospective design to examine the association between childhood ADHD symptoms and trauma exposure in young adulthood among Black/African American youth. Potential targets for intervention are proposed.

The Effect of Levetiracetam and Valproic Acid Treatment on Anger and Attention Deficit Hyperactivity Disorder Clinical Features in Children and Adolescents with Epilepsy: A Prospective Study.

Antiseizure medications (ASMs) can potentially trigger psychobehavioral adverse events associated with the onset or exacerbation of psychiatric symptoms such as irritability, aggression, and hyperactivity. The objective of this study was to evaluate the effects of levetiracetam and valproic acid on changes in clinical features of anger, attention deficit hyperactivity disorder (ADHD), and oppositional defiant disorder (ODD). The purpose was to furnish guidance on rational drug selection in children and adolescents with epilepsy to minimize psychiatric comorbidity in the treatment of epilepsy. This was a prospective, observational, cohort study involving treatment-naïve children aged 7-18 years with newly diagnosed generalized or focal epilepsy who were prescribed levetiracetam or valproic acid as monotherapy for a 6-month period and regularly followed up. Psychiatric assessment was conducted at the time of the new epilepsy diagnosis and at the six-month follow-up. These assessments were performed using the Schedule for Affective Disorders and Schizophrenia for School-Age Children Current and Lifetime Version (DSM-5), a structured psychiatric interview, as well as the State-Trait Anger Expression Style Inventory and Turgay DSM-IV Based Disruptive Behaviour Disorders Screening and Rating Scale. Anger subscores, ADHD symptoms, change in diagnosis, focal and generalized epilepsy groups, continuous seizures and seizure-free periods before and 6 months after treatment with valproic acid and levetiracetam were compared. A total of 50 children, 25 in the valproic acid group and 25 in the levetiracetam group, with a mean age of 11.92 ± 3.08 years, were included in the study. There was a statistically significant increase in the ADHD subscale score post-treatment among patients receiving levetiracetam (p = 0.045) and valproic acid (p = 0.034) compared with pre-treatment. The change in both anger-in and anger-out expression scores with treatment was significantly higher in patients receiving levetiracetam (p = 0.035) compared with those receiving valproic acid (p = 0.026). Statistically, there was a significant difference in the diagnostic criteria of the levetiracetam group pre- and post-treatment (p = 0.026). The proportion of patients in whom the diagnostic criteria for ADHD+ODD were fulfilled increased from 16% before treatment to 48% after treatment, a statistically significant increase (p = 0.026). This study found an increase in internalized anger features and ADHD symptom severity in children with epilepsy treated with valproic acid and levetiracetam. In those prescribed levetiracetam, there was a statistically significant rise in the proportion meeting the diagnostic criteria for ADHD + ODD. Our research is one of the first to prospectively examine the psychiatric assessment of children diagnosed with epilepsy. The remarkable results demonstrate changes in psychiatric diagnoses associated with the treatment of levetiracetam and valproic acid. Furthermore, a considerable rise in ADHD symptoms was observed in those treated with valproic acid.

How depression and ADHD relate to exercise addiction: a cross-sectional study among frequent exercisers.

To date, there are no official diagnostic criteria for the frequently reported phenomenon of exercise addiction. Therefore, the aim of the present study was to investigate how mental disorders, specifically depression and attention-deficit hyperactivity disorder (ADHD), are related to exercise addiction (EA). A total of 173 participants aged between 18 and 70 years, who reported exercising more than 10 h a week and continued to exercise despite injury or illness, answered questionnaires including the Exercise Dependence Scale, the Beck Depression Inventory, and the Homburger ADHD scale for adults. Multiple linear regression analyses were performed adjusting for relevant confounders (age, gender) and stepwise regression was used to identify which of the two mental disorders is the more influential predictor of EA. Pearson correlation analysis showed that depressive symptoms [r (171) = 0.422, p < 0.00] and ADHD symptoms [r (171) = 0.308, p < 0.001] were positively correlated with EA symptoms. The relation between depressive symptoms and EA remained after adjusting for confounders in the regression model (B = 20.531; t(170) = 5.950; 95% CI [13.719, 27.343]; p < 0.001). Similarly, the positive link between ADHD symptoms and EA persisted after controlling for confounders (B = 15.507; t(170) = 3.771; 95% CI [7.389, 23.625]; p < 0.001). Additionally, a stepwise regression model identified that depressive symptoms are a stronger predictor for EA than ADHD symptoms. Depressive symptoms seem to be a stronger predictor for EA compared to ADHD symptoms in frequent exercisers. Although individuals with ADHD May exercise extensively, they might be less at risk for EA than individuals with depression. These results contribute to the complex characterization of the psychiatric profile of individuals with exercise addiction, and underline the need for further research elucidating the interplay between mental disorders and EA.

Attention Deficit Hyperactivity Disorder Symptoms Among Students Attending Higher Educational Institution: A Cross-Sectional Study

Attention Deficit Hyperactivity Disorder Symptoms Among Students Attending Higher Educational Institution: A Cross-Sectional Study

Exploring the associations between symptom severity, metacognition, problematic social media use and cyberbullying in treatment naïve adolescents with Attention Deficit and Hyperactivity Disorder

This study investigates the relationship between ADHD symptom severity, metacognition, problematic social media use, and cyberbullying/cybervictimization in treatment-naïve adolescents. Understanding these relationships is vital for enhancing ADHD intervention strategies. Using a cross-sectional design, 97 adolescents meeting DSM-5 criteria for ADHD without any comorbidity and 97 healthy controls were assessed. Measures included the Metacognitions Questionnaire for Children, Social Media Disorder Scale, Revised Cyberbullying Inventory-II, and Revised Conners’ Parent Rating Scale-Short. The comparisons were performed with independent samples’ t tests and the associations were estimated by using Pearson’s bivariate correlations and multiple regression analyses. Results revealed that adolescents with ADHD exhibited higher levels of dysfunctional metacognitions, problematic social media use, cyberbullying, and cybervictimization compared to controls. Regression analysis showed significant positive associations between ADHD symptoms, specific metacognitions (e.g., positive meta-worry, cognitive monitoring), and problematic social media use. This study, the first of its kind among treatment-naïve ADHD adolescents, provides valuable insights into the relationship between ADHD symptoms and particular metacognitions (i.e. positive meta-worry, cognitive monitoring) and problematic social media use. These findings contribute to a deeper understanding of ADHD in adolescence and may inform the development of targeted prevention and treatment strategies, particularly relevant given adolescents’ susceptibility to social media’s influence and their potential for cognitive flexibility in rehabilitation contexts.

Pharmacological Interventions for Attention-Deficit/Hyperactivity Disorder in Children and Adolescents with Tourette Disorder: A Systematic Review and Network Meta-Analysis.

Objective: To evaluate the comparative efficacy of pharmacological interventions for children and adolescents with a dual diagnosis of persistent tic disorders or Tourette disorder and attention-deficit/hyperactivity disorder (TD + ADHD). Methods: We searched CENTRAL, Embase, PubMed, PsycInfo, Web of Sciences, ClinicalTrials.gov, and WHO ICTRP up to September 2023 to identify double-blinded randomized controlled trials (RCTs) assessing pharmacological interventions for children and adolescents with TD + ADHD. Outcomes were change in ADHD symptoms (primary) and tics (secondary) severity. Standardized mean difference (SMD) was calculated and pooled in random-effects network meta-analysis. The Confidence in Network Meta-Analysis framework was adopted to determine certainty of evidence. Results: We included 8 RCTs involving 575 participants. Network meta-analyses demonstrated that α2 agonists (SMD, 95% confidence interval [CI] ADHD: -0.72 [-1.13 to -0.31]; TD: -0.70 [-0.96 to -0.45]) and stimulants + α2 agonists (ADHD: -0.84 [-1.54 to -0.13]; TD: -0.60 [-1.04 to -0.17]) were more efficacious than placebo for ADHD symptoms and tics severity. Stimulants alone were more efficacious than placebo for ADHD symptoms severity only, but they did not worsen tics (ADHD: -0.54 [-1.05 to -0.03]; TD: -0.22 [-0.49 to 0.05]). There were no significant differences between any pairs of medications that were found efficacious against placebo for ADHD symptoms or tics severity. Certainty in the evidence varied from low to very low. Conclusions: Stimulants are efficacious for ADHD symptoms severity and do not increase tics severity in TD + ADHD. α2 agonists are efficacious for both ADHD symptoms and tics severity in TD + ADHD. These findings should inform guidelines and help guide shared decision-making to choose a medication for children with TD + ADHD.

Internet searches for ADHD medications surged during the COVID-19 pandemic

On January 2020, the World Health Organization (WHO) declared that Coronavirus Disease (COVID-19) had become a public health emergency of international concern (PHEIC) and was assessed as a pandemic in March 2020. For the next 2–3 years, Americans followed stay-at-home orders, and used virtual technologies, while struggling with pandemic-related stressors (1). This affected mental health (2). Attention-deficit hyperactivity disorder (ADHD) symptoms increased (3), resulting in an uptick in ADHD prescriptions (4). A shortage of Adderall was announced by the U.S. Food and Drug Administration (FDA) in October 2022. As actual prescription usage data were not available on the short time frame of the pandemic, we explored the potential of using internet searches as a proxy for real health behavior, with prevention of future shortages in mind. We used Google Trends (GT) data (5) to estimate public interest in ADHD medications during the pandemic.

The Association between Hyperactivity and Suicidal Behavior and Attempts among Children Referred from Emergency Departments.

The global prevalence of suicidal behaviors in children is rising, with attention-deficit hyperactivity disorder (ADHD) proposed as a contributing factor. This study examines the association between ADHD facets (hyperactivity and inattention) and suicidal behavior and attempts in children. Additionally, it seeks to compare self-reported ADHD symptoms and suicide-related incidents with parental reports. A cohort of 71 children referred from emergency departments due to suicidal thoughts and behaviors completed self- and parental report questionnaires. The results revealed that elevated hyperactivity scores, surpassing the ADHD diagnosis threshold, were significantly associated with increased rates of suicidal behavior. Hyperactivity demonstrated a stronger association with lifetime suicide attempts compared to inattention. Moreover, children's self-reported ADHD symptoms exhibited a stronger correlation with suicide attempts than parental reports. This study highlights the critical role of hyperactivity in understanding suicidal behaviors among children with ADHD. It underscores the importance of considering hyperactivity-related symptoms in assessment and treatment approaches for suicidal behavior in this population.

ADHD in Black Youth: A Content Analysis of Empirical Research from 1972 to 2023

Objective: The purpose of this content analysis study was to characterize patterns of research on Black youth with ADHD. Method: Relevant articles were identified through searching psychology and medical databases and cross-referencing citations in previously published review articles. The 204 empirical articles included in this study (1) were conducted in the United States, (2) had a predominantly child or adolescent sample, (3) had more than 80% Black youth/families in the study sample and/or conducted separate analyses for Black youth/families, and (4) examined ADHD symptoms or diagnoses. Articles were categorized into five primary content areas: Assessment, Treatment, Perceptions, Prevalence, and Associated Correlates. Journal characteristics, sample characteristics, and methodological characteristics are presented across these content areas. Results: Findings show a relatively low representation of Black youth with ADHD in the literature, with most studies using race comparative approaches and secondary data analyses, and many being published in medical journals. Conclusion: Based on these results, changes are recommended both at the individual study and broader systems levels (e.g., funding agencies). More research, funding, and publications centering Black youth with ADHD are vital to understanding and correcting long-standing health disparities for this community.

A Randomized Controlled Trial of a Virtually Delivered Group Parent Training for Parents of Children with ADHD During an Intensive Summer Treatment Program

ABSTRACT Background Behavioral Parent Training (BPT) is a widely implemented evidence-based treatment for youth with Attention-Deficit/Hyperactivity Disorder (ADHD) and related behavioral problems. During the COVID-19 pandemic, BPT was rapidly scaled for remote delivery via video conferencing platforms to enhance reach and engagement among families in need. Objective The purpose of the present study was to conduct a randomized controlled trial of a remotely delivered group-based BPT implemented in tandem with the Summer Treatment Program (STP) during the summer of 2021, the first year our clinic returned to in-person services following initial pandemic-related lockdowns. Method Children ranged in age from 6 to 12 years (M = 8.23, SD = 1.51) and were primarily male (93%) and Hispanic/Latine (74.4%). Families were randomly assigned to either receive the virtually delivered BPT during the summer (N = 23) or to a wait-list control group (N = 20), who received virtually delivered BPT in the fall. Results All families reported significant improvements in ADHD symptoms, related impairments, negative parenting behaviors, and knowledge of effective parenting skills from pre- to post-STP. Parents in the BPT group demonstrated additional improvements in managing difficult home situations. Conclusions Results of the study suggest that participating in BPT alongside the STP produces unique benefits for families above the standard behavioral treatment. Additionally, this study demonstrates the feasibility and utility of virtual group-based BPT to reduce burden associated with in-person services while providing evidence-based care in an inclusive manner.

The Impacts of Co-Occurring Developmental Language Disorder on the Academic, Interpersonal, and Behavioral Profiles of Children With Attention-Deficit/Hyperactivity Disorder

Purpose: Attention-deficit/hyperactivity disorder (ADHD) is a multifactorial disorder that has been linked to increased risk for behavioral, academic, and interpersonal problems. Developmental language disorder (DLD) has also been linked to poor outcomes in these areas. The presence of co-occurring disorders in children's profiles is generally associated with poorer outcomes relative to profiles consisting of only one disorder. This study investigated the extent to which co-occurring DLD in children already identified with ADHD presented increased risk for severity of their primary ADHD symptoms, the presence of secondary behavioral problems, and/or increased problems in the tertiary areas of academic performance and interpersonal interactions. Method: Data from 90 children from combined community-based and clinically based study samples were used in this retrospective study. Behavioral, academic, and social attributes were assessed from parent ratings on the Child Behavior Checklist. Results: Results indicated primary symptoms of ADHD and related tertiary interpersonal consequences were not increased when co-occurring DLD was present. However, the co-occurrence of DLD on ADHD resulted in increased risk for secondary externalizing problems and deficits in academic performance. Conclusions: Outcomes highlight the need for high-quality collaborations among clinical professionals, school-based professionals, and parents to ensure the complex needs of children with ADHD are adequately addressed. Children with ADHD who have elevated externalizing behaviors and who are struggling academically should be tested for possible co-occurring DLD.

Early emotion regulation developmental trajectories and ADHD, internalizing, and conduct problems symptoms in childhood.

Emotion dysregulation is considered a transdiagnostic factor with importance for a range of neurodevelopmental and mental health issues, including attention deficit hyperactivity disorder (ADHD) symptoms, internalizing problems, and conduct problems. Emotion regulation skills are acquired from early in life and are thought to strengthen gradually over childhood. Children, however, acquire these skills at different rates and slower acquisition may serve as a marker for neurodevelopmental and mental health issues. The current study uses the UK Millennium Cohort Study, a large longitudinal study to evaluate whether developmental trajectories of emotion regulation across ages 3, 5, and 7 predict levels of ADHD symptoms, internalizing problems, and conduct problems at age 7. Both higher initial levels of and slower reductions in emotion dysregulation across ages 3, 5, and 7 predicted higher ADHD symptoms, conduct problems, and internalizing problems at age 7 in both male and female children. Our findings suggest that monitoring trajectories of emotion regulation over development could help flag at-risk children. Additionally, supporting the acquisition of emotion regulation skills in this critical period could be a promising transdiagnostic preventive intervention.
