Predictors of Changes in Height, Weight, and Body Mass Index After Initiation of Central Nervous System Stimulants in Children with Attention Deficit Hyperactivity Disorder.

OBJECTIVE: To identify predictors of changes in height, weight, and body mass index (BMI) in children with attention deficit hyperactivity disorder (ADHD) starting central nervous system (CNS) stimulants. STUDY DESIGN: There were 230 medication-naïve children aged 5-12 years with ADHD who participated in a randomized trial evaluating the impact of CNS stimulants on growth over 30 months. This observational analysis focused on the 141 participants using study medication for 65 or more days in the first 6-months after starting medication. Biometric variables, ADHD, and oppositional defiant disorder symptom scores at medication initiation, and medication use over the study were examined as predictors of changes in standardized (z) height, weight, and BMI. RESULTS: Mean changes in z-BMI, z-weight. and z-height were negative throughout the study. The most consistent predictors of change in z-BMI, z-weight, and z-height were percent days medicated and total medication exposure. Children with lower z-height and z-weight at medication initiation experienced greater z-BMI and z-weight decreases over the first 6 months on medication. Greater appetite suppression during dose optimization predicted greater decreases in z-weight over the entire study and a greater decrease in z-height over the first 6 months on medication. z-weight change correlated with z-height change. Behavioral symptoms did not predict changes in z-BMI, z-weight, or z-height. CONCLUSIONS: How much and how often CNS stimulants are used predicts changes in z-BMI, z-weight, and z-height in children. Even smaller and lighter children may be at risk for decreases in z-weight and z-BMI. Parent ratings of appetite during dose titration may serve as feasible indicators of future weight and height change in children using CNS stimulants.

Adolescent Suicide Risk Screening: A Secondary Analysis of the SHIELD Randomized Clinical Trial.

OBJECTIVE: To evaluate the effectiveness of adolescent suicide risk screening to increase initiation of mental health services via a secondary analysis using data from the SHIELD (Screening in High Schools to Identify, Evaluate and Lower Depression) randomized clinical trial, which evaluated school-based screening for major depressive disorder (MDD). STUDY DESIGN: Students in 14 Pennsylvania high schools were randomized by grade to either the usual school practice of targeted referral for behavior raising a concern for suicide risk or universal screening using the Patient Health Questionnaire-9 (PHQ-9), with any response >0 to item 9 regarding suicide risk considered positive. Students identified in either arm were referred to the Student Assistance Program (SAP), which is mandated in all Pennsylvania schools. The SAP determined follow-up. Study groups were compared using mixed-effects logistic regression. RESULTS: The participants comprised 12 909 students, with 6473 (50.1%) randomized to universal screening. The study group was 46% female and 43% Hispanic or non-Hispanic Black. Adolescents in the universal screening arm had 7.1-fold greater odds (95% CI, 5.7-8.8) of being identified as at risk for suicide, 7.8-fold greater odds (95% CI, 4.6-13.1) of follow-up needs, and 4.0-fold greater odds (95% CI, 2.0-7.9) of initiating mental health treatment. CONCLUSIONS: Although the PHQ-9 is a MDD screening tool, its use in universal screening increased identification and treatment initiation for adolescents at risk for suicide. This confirms the value of universal screening and suggests that a suicide-specific risk assessment would have even greater impact on treatment initiation for identified youth. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03716869.

The significance of limited prosocial emotions among externalizing disorders in children.

Limited Prosocial Emotion (LPE) specifier of conduct disorder (CD) includes lack of remorse or guilt, callousness/lack of empathy, unconcern about performance, and shallow/deficient affect. Given the relatively recent inclusion of the LPE specifier in the Diagnostic and Statistical Manual, fundamental information is still unknown about LPE, such as how common the different domains are, how much they overlap with one another, whether they predict unique variance from each other, and the potential for the LPE specifier as a transdiagnostic facet of externalizing problems. Caregivers (n = 1,50) of children (Mage = 8.42, SD = 2.31) completed a questionnaire assessing individual LPE domains and measures of externalizing symptoms. Results showed that LPE specifier domains were highly related but separable. All LPEs were uniquely associated with oppositional defiant disorder (ODD), CD, and overall impairment after controlling for other LPE items, child sex, and ADHD symptoms. Being unconcerned about performance, emotionally manipulative, and having shallow/deficient affect were uniquely associated with ADHD while controlling for ODD and CD symptomatology. Our findings fit with the historical conceptualization of LPE as a unidimensional construct and contributes to the growing evidence of the potential utility of assessing LPE across externalizing disorders in children. Future research should look to replicate and extend our findings in clinical samples of youth.

Randomized Trial of First-Line Behavioral Intervention to Reduce Need for Medication in Children with ADHD.

A study conducted in an analogue summer treatment setting showed that when concurrently receiving behavioral intervention, many children with Attention-Deficit Hyperactivity Disorder (ADHD) did not need medication or maximized responsiveness at very low doses. The present study followed participants in that summer study into the subsequent school year to investigate whether the same pattern would extend to the natural school and home settings. There were 127 unmedicated children with ADHD between the ages of 5 and 13 who were randomly assigned to receive or not receive behavioral consultation (BC) at the start of the school year. Children were evaluated by teachers and parents each week to determine if central nervous system stimulant treatment was needed. Children who received BC were approximately half as likely those who did not (NoBC) to initiate medication use each week at school or home and used lower doses when medicated at school. This produced a 40% reduction in total methylphenidate exposure over the course of the school year. BC and NoBC groups did not significantly differ on end-of-year teacher or parent ratings of behavior, which were positive. Moreover, BC and NoBC groups did not significantly differ in cost of treatment; although children in the BC condition accrued additional costs via the BC, these costs were offset by the associated delay and reduction in medication use. Results add to a growing literature suggesting that the use of low-intensity behavioral intervention as a first-line treatment reduces or eliminates the need for medication in children with ADHD.

How do stimulant treatments for ADHD work? Evidence for mediation by improved cognition.

BACKGROUND: Stimulant medications such as methylphenidate (MPH) are the frontline treatment for Attention-Deficit/Hyperactivity Disorder (ADHD). Despite their well-documented efficacy, the mechanisms by which stimulants improve clinical outcomes are not clear. The current study evaluated whether MPH effects on classroom behavior were mediated by improved cognitive functioning. METHODS: Children with ADHD (n = 82; 9-12 years old) participated in a week-long summer research camp, consisting of cognitive testing, classroom periods, and recreational activities. After a baseline day, participants completed a 3-day randomized, double-blind, placebo-controlled trial of MPH (at doses approximating 0.3 and 0.6 mg/kg of immediate-release MPH dosed TID). Cognitive domains included inhibitory control (Stop Signal Task and prepulse inhibition of startle), attention (Continuous Performance Task and reaction time variability), and working memory (forward and backward spatial span). Clinical outcomes included math seatwork productivity and teacher-rated classroom behavior. A within-subjects path-analytic approach was used to test mediation. MPH-placebo and dose-response contrasts were used to evaluate drug effects. RESULTS: Methylphenidate improved seatwork productivity and teacher ratings (ds = 1.4 and 1.1) and all domains of cognition (ds = 0.3-1.1). Inhibitory control (Stop Signal Task, SST) and working memory backward uniquely mediated the effect of MPH (vs. placebo) on productivity. Only working memory backward mediated the impact of MPH on teacher-rated behavior. The dose-response (0.6 vs. 0.3 mg/kg) effects were more modest for clinical outcomes (ds = 0.4 and 0.2) and cognition (ds = 0-0.3); there was no evidence of cognitive mediation of the clinical dose-response effects. CONCLUSIONS: These findings are novel in demonstrating that specific cognitive processes mediate clinical improvement with stimulant treatment for ADHD. They converge with work on ADHD theory, neurobiology, and treatment development in suggesting that inhibitory control and working memory may be mechanisms of stimulant treatment response in ADHD. More work is necessary to evaluate the degree to which these findings generalize to chronic treatment, a broader array of clinical outcomes, and nonstimulant treatments.

Treatment Sequencing for Childhood ADHD: A Multiple-Randomization Study of Adaptive Medication and Behavioral Interventions.

Behavioral and pharmacological treatments for children with attention deficit/hyperactivity disorder (ADHD) were evaluated to address whether endpoint outcomes are better depending on which treatment is initiated first and, in case of insufficient response to initial treatment, whether increasing dose of initial treatment or adding the other treatment modality is superior. Children with ADHD (ages 5-12, N = 146, 76% male) were treated for 1 school year. Children were randomized to initiate treatment with low doses of either (a) behavioral parent training (8 group sessions) and brief teacher consultation to establish a Daily Report Card or (b) extended-release methylphenidate (equivalent to .15 mg/kg/dose bid). After 8 weeks or at later monthly intervals as necessary, insufficient responders were rerandomized to secondary interventions that either increased the dose/intensity of the initial treatment or added the other treatment modality, with adaptive adjustments monthly as needed to these secondary treatments. The group beginning with behavioral treatment displayed significantly lower rates of observed classroom rule violations (the primary outcome) at study endpoint and tended to have fewer out-of-class disciplinary events. Further, adding medication secondary to initial behavior modification resulted in better outcomes on the primary outcomes and parent/teacher ratings of oppositional behavior than adding behavior modification to initial medication. Normalization rates on teacher and parent ratings were generally high. Parents who began treatment with behavioral parent training had substantially better attendance than those assigned to receive training following medication. Beginning treatment with behavioral intervention produced better outcomes overall than beginning treatment with medication.

Comparative Cost Analysis of Sequential, Adaptive, Behavioral, Pharmacological, and Combined Treatments for Childhood ADHD.

We conducted a cost analysis of the behavioral, pharmacological, and combined interventions employed in a sequential, multiple assignment, randomized, and adaptive trial investigating the sequencing and enhancement of treatment for children with attention deficit hyperactivity disorder (ADHD; Pelham et al., 201X; N = 146, 76% male, 80% Caucasian). The quantity of resources expended on each child's treatment was determined from records that listed the type, date, location, persons present, and duration of all services provided. The inputs considered were the amount of physician time, clinician time, paraprofessional time, teacher time, parent time, medication, and gasoline. Quantities of these inputs were converted into costs in 2013 USD using national wage estimates from the Bureau of Labor Statistics, the prices of 30-day supplies of prescription drugs from the national Express Scripts service, and mean fuel prices from the Energy Information Administration. Beginning treatment with a low-dose/intensity regimen of behavior modification (large-group parent training) was less costly for a school year of treatment ($961) than beginning treatment with a low dose of stimulant medication ($1,669), regardless of whether the initial treatment was intensified with a higher "dose" or if the other modality was added. Outcome data from the parent study (Pelham et al., 201X) found equivalent or superior outcomes for treatments beginning with low-intensity behavior modification compared to intervention beginning with medication. Combined with the present analyses, these findings suggest that initiating treatment with behavior modification rather than medication is the more cost-effective option for children with ADHD.

Treatment Utilization Pattern of Preschool Children With Attention-Deficit/Hyperactivity Disorder.

OBJECTIVE: The aim of this study was to identify patterns of ADHD care, including factors that guide selection and sequencing of treatments in a large nationwide sample of preschool-aged youth over the past 6 years. METHOD: A retrospective cohort study utilizing a large electronic health record (TriNetX) of nearly 24,000 children ages 3 to 6 diagnosed with ADHD. RESULTS: One in three preschoolers with ADHD were prescribed psychotropic medication, most commonly methylphenidate and guanfacine. One in 10 had at least one psychotherapy billing code during the entire assessment with most youth starting medication before psychotherapy. Rates of most treatments, including polypharmacy, increased with comorbid psychiatric disorders or sleep problems and over the course of the coronavirus pandemic. CONCLUSION: Rates of treatment have increased over time but are still largely inconsistent with published care guidelines that advise therapy before medication. Clinicians appear to prioritize psychiatric comorbidity and sleep problems when selecting treatments.

Synthetic Marijuana: Assessment of Usage, Motivation and Associated Risks in Adolescent Substance Users.

Objectives: Use of Synthetic and designer products, including synthetic marijuana (SM), among adolescents poses a major risk to public health. Little is known about the motivating factors of synthetic substance use in adolescents. This study examined the motivations, predictors, perceived risks and benefits, and differences with SM versus natural marijuana among adolescents. Methods: Between April 2016 and May 2018, a convenience sample of adolescents receiving substance use treatment from a local counseling center completed an anonymous survey to assess the use of natural and synthetic marijuana use, the Strengths and Difficulties Questionnaire to assess levels of current psychiatric symptoms and the Community Assessment of Psychic Experiences-Positive Scale to assess symptoms of psychosis. Results: A total of 80 adolescents (age range of 14-18 years; 71% male; 53% Caucasian) completed the study. Of these, 39 (49%) reported natural marijuana use (natural marijuana users) and 41 (51%) reported both synthetic and natural marijuana use (dual users). The most commonly reported reasons for using SM were its low cost and reduced risk of detection. Participants who were familiar with SM and reported a desire to avoid detection on drug tests were likelier to use SM (all P < .05). Dual users reported more benefits and risks associated with SM use when compared to natural marijuana users (P ⩽ .05). The use of SM also heightened the perceived medical risks of natural marijuana, including seizures and respiratory issues (P < .05), compared with natural marijuana users. While dual users self-reported more conduct (P = .009) and externalizing problems (P = .024) when compared to natural marijuana users, there were no group differences in psychotic symptoms, nor correlations with the frequency of synthetic or natural marijuana use and psychotic symptoms except that persecutory ideation correlated with the frequency of natural marijuana use during the past 12 months (rp = 0.28, P = .04). Conclusions: These results suggest that reports of cost savings, and lack of detection on urine drug screens are common reasons for SM use in adolescents despite being aware of the risks of using SM. Perceived benefits of using synthetics and other novel substances appear diverse, and merit further exploration as a better understanding of what motivates adolescents to use specific novel substances may guide prevention and treatment efforts.

From Consensus Statement to Pills to Pixels: New Innovations in Attention-Deficit/Hyperactivity Disorder Care.

Objectives: This review aims to present recent innovations and advancements in attention-deficit/hyperactivity disorder (ADHD) care, encompassing international consensus statement, new medication formulations, digital therapeutics, and neurostimulation devices. Methods: A comprehensive literature search of relevant articles published in the past five years was conducted, emphasizing the evidence base, efficacy, safety, and practical implications of these advancements. Results: The World Federation of ADHD Consensus Statement offers an updated diagnostic and treatment framework rooted in global scientific evidence. There are several newer ADHD medication formulations, including a nonstimulant (Viloxazine extended release) and the first transdermal amphetamine patch approved to treat ADHD. These options offer some unique benefits to personalize treatment based on symptom profile, lifestyle, preferences, and response. Digital tools offer additional means to restructure environments for individuals with ADHD, reducing impairment and reliance on others. In addition, digital therapeutics enhance access, affordability, personalization, and feasibility of ADHD care, complementing or augmenting existing interventions. Trigeminal nerve stimulation emerges as a well-tolerated nonpharmacological, device-based treatment for pediatric ADHD, with initial trials indicating effect sizes comparable to nonstimulant medications. Conclusions: These innovations in ADHD care represent clinically significant new treatment options and opportunities for personalized care. Health care professionals should integrate these developments into clinical practice, mindful of individual patient and family needs and preferences. Future research should assess long-term outcomes, cost-effectiveness, and acceptability of these innovations.

Attention-deficit/hyperactivity disorder in adolescence predicts onset of major depressive disorder through early adulthood.

BACKGROUND: The aim of this study was to examine the prospective relationship between a history of attention-deficit/hyperactivity disorder (ADHD) assessed in mid-adolescence and the onset of major depressive disorder (MDD) through early adulthood in a large school-based sample. A secondary aim was to examine whether this relationship was robust after accounting for comorbid psychopathology and psychosocial impairment. METHOD: One thousand five hundred seven participants from the Oregon Adolescent Depression Project completed rating scales in adolescence and structured diagnostic interviews up to four times from adolescence to age 30. RESULTS: Adolescents with a lifetime history of ADHD were at significantly higher risk of MDD through early adulthood relative to those with no history of ADHD. ADHD remained a significant predictor of MDD after controlling for gender, lifetime history of other psychiatric disorders in adolescence, social and academic impairment in adolescence, stress and coping in adolescence, and new onset of other psychiatric disorders through early adulthood (hazard ratio, 1.81; 95% confidence interval, 1.04, 3.06). Additional significant, robust predictors of MDD included female gender, a lifetime history of an anxiety disorder, and poor coping skills in mid-adolescence, as well as the onset of anxiety, oppositional defiant disorder, and substance-use disorder after mid-adolescence. CONCLUSIONS: A history of ADHD in adolescence was associated with elevated risk of MDD through early adulthood and this relationship remained significant after controlling for psychosocial impairment in adolescence and co-occurring psychiatric disorders. Additional work is needed to identify the mechanisms of risk and to inform depression prevention programs for adolescents with ADHD.

Editorial: Can Too Much Positive Emotion Be Bad for You?

There has been increasing focus on the assessment and treatment of irritability over the past decade in recognition of the impairment produced by abnormally persistent or excessive displays of negative emotions. However, emotional dysregulation may not be valence specific, and the impact of excessive or abnormally persistent displays of positive affect has received little attention. In their review in this issue of the Journal, Vogel et al.1 argue that it should receive more attention. They do an admirable job synthesizing the developmental and clinical literature to support the potential value of assessing the capacity to regulate positive affect in an attempt to determine if too much of good thing can in fact be bad for you.

Systematic Review and Meta-analysis: Pharmacological and Nonpharmacological Interventions for Persistent Nonepisodic Irritability.

OBJECTIVE: This meta-analysis examined the efficacy of available pharmacological and nonpharmacological interventions for irritability among youth with autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), disruptive behavior disorders (DBD), disruptive mood dysregulation disorder (DMDD), and/or severe mood dysregulation (SMD). METHOD: Literature searches were conducted in October 2020, resulting in 564 abstracts being reviewed to identify relevant papers, with 387 articles being reviewed in full. A random effects model was used for the meta-analysis, with subgroup meta-regressions run to assess effects of study design, intervention type, medication class, and clinical population. RESULTS: A total of 101 studies were included (80 pharmacological, 13 nonpharmacological, 8 combined). Despite high heterogeneity in effects (I2 = 94.3%), pooled posttreatment effect size for decreasing irritability was large (Hedges' g = 1.62). Large effects were found for pharmacological (g = 1.85) and nonpharmacological (g = 1.11) interventions; moderate effects were found for combined interventions relative to monotherapy interventions (g = 0.69). Antipsychotic medications provided the largest effect for reducing irritability relative to all other medication classes and nonpharmacological interventions. A large effect was found for youth with ASD (g = 1.89), whereas a medium effect was found for youth with ADHD/DMDD/DBD/SMD (g = 0.64). CONCLUSION: This meta-analysis provides a comprehensive review of interventions targeting persistent nonepisodic irritability among youth with various psychiatric disorders. Strong evidence was found for medium-to-large effects across study design, intervention type, and clinical populations, with the largest effects for pharmacological interventions, particularly antipsychotic medications and combined pharmacological interventions, and interventions for youth with ASD.

Effects of a Primary Care-Based Engagement Intervention for Improving Use of ADHD Treatments.

INTRODUCTION: Uptake of attention deficit hyperactivity disorder (ADHD) treatments is low in primary care. A quasi-experimental study assessed the impact of a primary care-based engagement intervention to improve ADHD treatment use. METHOD: Families of children with ADHD from four pediatric clinics were invited to participate in a two-stage intervention. The first step was an assessment battery to assess functioning and identify goals, followed by an in-office engagement session run by primary care staff. RESULTS: Of the 636 invited families, 184 (28.9%) completed ratings, with 95 (51%) families completing the engagement session. ADHD office visits varied based on the number of steps completed (0-2). ADHD prescriptions decreased over time in families completing neither step but increased for children previously unmedicated whose parents completed either step. Families completing both steps had the highest rates of nonmedication ADHD treatments. DISCUSSION: A brief two-step engagement intervention was associated with increased uptake of ADHD treatments.

Narrative Review: Impairing Emotional Outbursts: What They Are and What We Should Do About Them.

OBJECTIVE: Impairing emotional outbursts, defined by extreme anger or distress in response to relatively ordinary frustrations and disappointments, impact all mental health care systems, emergency departments, schools, and juvenile justice programs. However, the prevalence, outcome, and impact of outbursts are difficult to quantify because they are transdiagnostic and not explicitly defined by current diagnostic nosology. Research variably addresses outbursts under the rubrics of tantrums, anger, irritability, aggression, rage attacks, or emotional and behavioral dysregulation. Consistent methods for identifying and assessing impairing emotional outbursts across development or systems of care are lacking. METHOD: The American Academy of Child and Adolescent Psychiatry Presidential Task Force (2019-2021) conducted a narrative review addressing impairing emotional outbursts within the limitations of the existing literature and independent of diagnosis. RESULTS: Extrapolating from the existing literature, best estimates suggest that outbursts occur in 4%-10% of community children (preschoolers through adolescents). Impairing emotional outbursts may respond to successful treatment of the primary disorder, especially for some children with attention-deficit/hyperactivity disorder whose medications have been optimized. However, outbursts are generally multi-determined and often represent maladaptive or deficient coping strategies and responses. CONCLUSION: Evidence-based strategies are necessary to address factors that trigger, reinforce, or excuse the behaviors and to enhance problem-solving skills. Currently available interventions yield only modest effect sizes for treatment effect. More specific definitions and measures are needed to track and quantify outbursts and to design and assess the effectiveness of interventions. Better treatments are clearly needed.

Single and Combined Effects of Multiple Intensities of Behavioral Modification and Methylphenidate for Children with ADHD in the Home Setting.

Behavioral treatment, stimulants, and their combination are the recommended treatments for childhood attention-deficit/hyperactivity disorder (ADHD). The current study utilizes within-subjects manipulations of multiple doses of methylphenidate (placebo, 0.15, 0.30, and 0.60 mg/kg/dose t.i.d.) and intensities of behavioral modification (no, low, and high intensity) in the summer treatment program (STP) and home settings. Outcomes are evaluated in the home setting. Participants were 153 children (ages 5-12) diagnosed with ADHD. In alignment with experimental conditions implemented during the STP day, parents implemented behavioral modification levels in three-week intervals, child medication status varied daily, and the orders were randomized. Parents provided daily reports of child behavior, impairment, and symptoms and self-reported parenting stress and self-efficacy. At the end of the study, parents reported treatment preferences. Stimulant medication led to significant improvements across all outcome variables with higher doses resulting in greater improvement. Behavioral treatment significantly improved child individualized goal attainment, symptoms, and impairment in the home setting and parenting stress and self-efficacy. Effect sizes indicate that behavioral treatment combined with a low-medium dose (0.15 or 0.30 mg/kg/dose) of medication results in equivalent or superior outcomes compared to a higher dose (0.60 mg/kg/dose) of medication alone. This pattern was seen across outcomes. Parents overwhelmingly reported preferring treatment with a behavioral component as a first-choice treatment (99%). Results underscore the need to consider dosing as well as parent preference when utilizing combined treatment approaches. This study provides further evidence that combining behavioral treatment and stimulant medication may reduce the stimulant dose needed for beneficial effects.

Updates in Pharmacologic Strategies for Emotional Dysregulation in Attention Deficit Hyperactivity Disorder.

Emotional dysregulation (ED) manifesting as irritability or aggression produces appreciable impairment in children with attention deficit hyperactivity disorder and a main reason why they present for treatment. Central nervous system (CNS) stimulants seem to be a safe and tolerable treatment of most youth with these presentations. Optimization of CNS stimulants dose in combination with psychosocial interventions led to reductions in ED. Randomized controlled trials support that addition of risperidone further reduces aggression when these treatments are not sufficient. There is evidence for the efficacy of divalproex, molindone and selective serotonin reuptake inhibitor improve these outcomes when used as adjunct to CNS stimulants.

Psychometric Properties of Parent Ratings on the Inventory of Callous-Unemotional Traits in a Nationally Representative Sample of 5- to 12-Year-Olds.

The psychometric properties of the parent-report version of the Inventory of Callous-Unemotional Traits (ICU) in school-aged children requires further examination. In a nationally representative sample of U.S. children (N = 1,064, M age = 8.42, 51.7% boys), the current study examined the factor structure, measurement invariance, and the moderating role of parent rated ICU scores on conduct problems. Results supported (a) a two-factor model consisting of a CU factor and a limited prosocial emotions (LPE) factor; (b) an invariant structure of the ICU across child sex, as well as (to a lesser extent) across child age and parent sex; and (c) the moderating role of the LPE factor on the relationship between conduct problems and relevant outcomes (i.e., impairment, need for treatment). Normative data on the parent-report version of the ICU for elementary-aged school children in the United States were also presented. Clinical implications regarding use of the parent-report version of the ICU for school-aged children are discussed.

Associations among ADHD symptoms, ODD symptoms, and borderline personality features: A network analysis.

Attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) are common childhood syndromes that exhibit a high degree of comorbidity. Both ADHD and ODD symptoms in childhood predict higher levels of borderline personality features (BPF) later in development. Yet ADHD, ODD, and BPF each consist of a heterogeneous group of symptoms, and symptom-level associations between these groups remain unclear. The present study examined symptom-level associations, as well as sex differences in symptom-level associations, among ADHD, ODD, and BPF using network analysis. Caregivers of 962 children between the ages of 5 and 12 completed rating scales of ADHD, ODD, and BPF. Assessment of Bridge Expected Influence indicated a number of bridge symptoms linking ADHD to ODD; these bridge symptoms were primarily from the hyperactive-impulsive (rather than the inattentive) dimension of ADHD (e.g., blurts out answers, leaves seat, runs excessively). A smaller number of bridge symptoms were identified linking ADHD and ODD to BPF, and these bridge symptoms were different for girls versus boys. Overall, several ADHD hyperactive-impulsive symptoms were related to the BPF item gets in trouble for doing things without thinking, and the ODD item touchy/easily annoyed was related to the BPF item goes back and forth between different feelings. Moreover, whereas we observed stronger links between ODD antagonistic symptoms (e.g., blames others) and BPF among girls, we observed stronger links between ODD oppositional symptoms (e.g., defies/refuses to comply) and BPF among boys. Taken together, results provide a more nuanced, symptom-level understanding of the overlap among ADHD, ODD, and BPF.
