The Phenomenology of Outbursts

Treating pediatric aggressive behaviors and comorbid conditions

INTRODUCTION

Aggressive behaviors in children and adolescents can significantly impair quality of life, leading to disruptions in both academic and social functioning. Despite decades of research, a standardized nosology for aggressive behaviors remains lacking, resulting in considerable variability in the design of treatment trials for aggression.

AREAS COVERED

A comprehensive literature review was conducted to identify studies evaluating pharmacological treatments for aggressive behaviors in children and adolescents. Articles were sourced from multiple databases, focusing studies that investigated the use of medications for treating aggression, conduct problems, and disruptive behaviors.

EXPERT OPINION

A significant barrier to effectively treating childhood aggression is the absence of a clear and standardized nosology. Aggression is frequently regarded as a symptom rather than a distinct clinical entity, complicating treatment decisions and hindering the ability to predict outcomes and develop targeted interventions. Notably, impulsive aggression has been the primary focus of research as a target for pharmacotherapy, highlighting the need to expand our understanding of aggression subtypes. A paradigm shift is necessary, emphasizing the development of operational definition of aggression diagnosis based on the type of aggressive behavior, the creation of screening tools, and the prediction of treatment outcomes to enhance both clinical practice and research.

Research Agenda in Childhood Impairing Emotional Outbursts: A Report of the AACAP Presidential Taskforce on Emotional Dysregulation

Objective

As part of the 2019-2021 presidential term of the American Academy of Child and Adolescent Psychiatry (AACAP), the AACAP Presidential Initiative on Emotion Dysregulation in Youth Taskforce was established. The aim was to address emotion dysregulation in children and adolescents, focusing on developing methods for clinicians to identify, characterize, and treat impairing emotional outbursts along with development of a research agenda that would guide relevant researchers and research funders. One method to characterize emotion dysregulation was accomplished by recommendations for use of a diagnostic code that is available in the DSM. The research agenda is presented here.

Method

The Taskforce specifically focused on aggressive behaviors and emotions associated with outbursts. The development of a research agenda took place over 2 years of examination of the current needs in the literature, with contributions from experts in the field. This work dovetailed with the efforts from the Congress on Pediatric Irritability and Dysregulation, which had been meeting since 2015 to advance research into the measurement, pathophysiology, and treatment of emotion regulation problems in youth. We concentrated on the central questions concerning the measurement of outbursts, key questions linking outbursts to other psychopathologies, and how behavior in outbursts is separable from typical behavior.

Results

A description of the qualitative data gathering process is provided here, along with the following: recommendations in the research areas of measurement; pathophysiology; delineating outbursts from other psychopathologies; exploring the cultural, social, and interpersonal aspects of outbursts; understanding the prevention and treatment of outbursts; and exploring how outbursts manifest and are treated based on setting. Specific examples of research opportunities and future directions are provided.

Conclusion

A call is made to funding agencies to examine the spaces within their strategic plans that will allow for engagement in critical efforts to improve the lives of children and adolescents with severe emotional outbursts-some of the most impaired individuals presenting for care in child and adolescent psychiatry.

Stimulant Medication Shortens the Duration of Impairing Emotional Outbursts

Objective

Emotional dysregulation, often presenting as severe emotional outbursts, is being increasingly recognized as a source of considerable impairment for individuals with attention-deficit/hyperactivity disorder (ADHD). The aim of this study was to conduct a secondary analysis of data examining the impact of standing stimulant medication on the duration of emotional outbursts.

Method

The as needed (PRN)-medicated outbursts of psychiatrically hospitalized children, 5 to 12 years of age, were tracked by psychiatric nurses using the Behavioral Activity Rating Scale from the time of PRN administration until the child became calm. The impact of extended-release (ER), immediate-release (IR) stimulant and dose, type and reason for outburst/PRN (aggression, agitation, distress), standing concomitant psychotropic medications and time of day, and days since admission were examined.

Results

Forty-seven children had a total of 405 outbursts, 96 of which occurred when no stimulant was prescribed and 309 with stimulant medication. Controlling for time of day and standing neuroleptic dose, outbursts that occurred on an ER stimulant medication were statistically significantly shorter than those that occurred on no stimulant by about 20 minutes (52.7 vs 72.4 minutes), or 30 minutes for aggressive outbursts. Results were unchanged when further controlling for stimulant type and dose, α-agonist, days since admission, PRN medication type, or reason for PRN/outburst. Immediate-release stimulants and short-acting stimulants did not shorten outburst duration.

Conclusion

In children with ADHD with severe outbursts, ER stimulants were associated with shorter outburst duration than IR stimulants.

Preliminary psychometric properties of the Brazilian Portuguese version of the emotional outburst questionnaire

This study focuses on the cross-cultural adaptation of the Emotional Outburst Questionnaire (EOQ) to Brazilian Portuguese and preliminarily assesses its predictive validity. The EOQ evaluates aspects of emotional outbursts (EO), including frequency, duration, intensity, types, associated behaviours, recovery time, triggers, and effectiveness of calming strategies. Two independent translators performed the translation, with subsequent synthesis and analysis revealing that only 33 items (24.81%) required revision. Among these, one item needed partial modification, and two needed total modification. The study demonstrated strong content validity and adaptation in terms of conceptual, idiomatic, and semantic aspects. The EOQ's predictive validity was assessed by analysing the interruption of mental health services in Brazil due to Covid-19 (T1) compared to when services resumed after social distancing measures were lifted (T2). Parents of 25 individuals with developmental disabilities (ASD, DS and ID), with a mean of 11 y/o, mostly male (76%), completed the EOQ. Service interruption during T1 led to increased frequency and duration of severe emotional outbursts reported by caregivers compared to T2 (frequency: p < .001; duration: p = 0.05). This suggests that the EOQ exhibits predictive validity and sensitivity to changes influenced by individual contexts. These findings highlight the EOQ's potential as an outcome measure for intervention development.

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.

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.

Management of Emotion Dysregulation and Outbursts in Children and Adolescents

PURPOSE OF REVIEW

Emotion dysregulation and outbursts are very common reasons for referral to child and adolescent mental health services and a frequent cause of admission to hospitals and residential programs. Symptoms of emotion dysregulation and outburst are transdiagnostic, associated with many disorders, have the potential to cause severe impairment and their management presents a major challenge in clinical practice.

RECENT FINDINGS

There are an increasing number of psychosocial interventions that demonstrate promise in improving emotion dysregulation and outbursts. Acute care systems to manage the most severely ill patients have limited best practice guidelines but program advancements indicate opportunities to improve care models. Pharmacotherapy may be of assistance to psychosocial interventions but must be used with caution due to potential adverse effects. Much remains to be discovered however evidence informed, targeted treatments for specific populations show potential for future improvements in outcomes.

Large-scale functional brain networks of maladaptive childhood aggression identified by connectome-based predictive modeling

Disruptions in frontoparietal networks supporting emotion regulation have been long implicated in maladaptive childhood aggression. However, the association of connectivity between large-scale functional networks with aggressive behavior has not been tested. The present study examined whether the functional organization of the connectome predicts severity of aggression in children. This cross-sectional study included a transdiagnostic sample of 100 children with aggressive behavior (27 females) and 29 healthy controls without aggression or psychiatric disorders (13 females). Severity of aggression was indexed by the total score on the parent-rated Reactive-Proactive Aggression Questionnaire. During fMRI, participants completed a face emotion perception task of fearful and calm faces. Connectome-based predictive modeling with internal cross-validation was conducted to identify brain networks that predicted aggression severity. The replication and generalizability of the aggression predictive model was then tested in an independent sample of children from the Adolescent Brain Cognitive Development (ABCD) study. Connectivity predictive of aggression was identified within and between networks implicated in cognitive control (medial-frontal, frontoparietal), social functioning (default mode, salience), and emotion processing (subcortical, sensorimotor) (r = 0.31, RMSE = 9.05, p = 0.005). Out-of-sample replication (p < 0.002) and generalization (p = 0.007) of findings predicting aggression from the functional connectome was demonstrated in an independent sample of children from the ABCD study (n = 1791; n = 1701). Individual differences in large-scale functional networks contribute to variability in maladaptive aggression in children with psychiatric disorders. Linking these individual differences in the connectome to variation in behavioral phenotypes will advance identification of neural biomarkers of maladaptive childhood aggression to inform targeted treatments.

Of Triggers, Tigers, and Tactics: Managing Emotional Dysregulation

The frustration of defining, understanding, and addressing irritability in child psychiatry and the difficulties that children with emotion dysregulation face on a daily basis can be seen as parallel processes. We know that irritability is one of the most common reasons for which children are referred for evaluation.¹ We also know that the stakes are extremely high, with persistent irritability associated with suicidality.² Despite this, we do not have a readily available nosological paradigm. Our current clinical approach remains muddled by outbursts' transdiagnostic nature. We find ourselves listing things such as posttraumatic stress disorder, disruptive mood dysregulation disorder, attention-deficit/hyperactivity disorder, anxiety, and depressive disorders in the chart, but feeling that we have not fully captured the unique neurobiological and subjective essence of a child's irritability syndrome.³ Furthermore, despite extensive research, we lack accessible diagnostic tools or effective treatment protocols to implement on a community-wide basis. So, we (JC, CU) think we have every right to be irritable as we experience frustrative non-reward (thinking and focusing on this issue with blocked goal attainment) and face existential threat (desperately wanting children and families to enjoy better developmental trajectories, and wanting it now!).⁴.

Evidence Base Update for Questionnaires of Emotion Regulation and Reactivity for Children and Adolescents

Objective: Emotion regulation (ER) is a multi-faceted and dynamic process relevant to both normative emotional development and transdiagnostic emotional dysfunction for a range of psychological disorders. There has been tremendous growth in ER research over the past decade, including the development of numerous new measures to assess ER. This Evidence Base Update included a systematic review to identify self- and informant-report questionnaire measures of ER for children and adolescents, including measures of ER strategies and effectiveness (or emotion dysregulation).Methods: PubMed, PsycInfo, and Health and Psychosocial Instruments databases were searched using the terms emotion OR affect AND regulation OR control OR reactivity OR response, as well as terms related to questionnaires and psychometrics, restricted to articles on youth (< 18 years old). Each measure's psychometrics was evaluated based on modified criteria by De Los Reyes and Langer (2018).Results: Nine-hundred ninety-seven papers were identified yielding 87 measures that met inclusion for review. Although the majority (60%) of identified ER measures could not be recommended based on these criteria, 8% were Excellent, 14% were Good, and 17% were Adequate. The recommended measures included: 11 general ER measures (5 focused on strategies, 5 focused on dysregulation/ effectiveness), 13 measures of ER as it relates to specific emotions or contexts such as irritability or peer stress (4 focused on strategies, 9 focused on dysregulation/effectiveness), and 11 measures of other constructs that include an ER subscale (all focused on dysregulation). Conclusions: The characteristics, strengths, and weaknesses of the recommended ER measures are described in order to guide measure selection for clinical or research uses. A synthesis of themes identified during this review includes commonly observed areas of weakness and gaps in the literature to provide a foundation for future research and measure development.

Explosive Outbursts at School

Explosive outbursts (EO) by students are an intensely distressing experience for that student as well as for all school staff and students present during the outburst. These EO are characterized by rapid escalations, usually far out of proportion to precipitating events, may include significant verbal and/or physical aggression, require intensive staff intervention, are often difficult for the student to process, and are typically recurrent. These explosions cross multiple psychiatric and educational diagnostic categories and require diverse interventions to address behavioral, emotional, impulsive, and sensory components. Interventions for each stage of an EO can be used to deescalate these events.
