Psychiatric Symptom Impairment in Children with Autism Spectrum Disorders

Characterization and Outcomes of Profoundly and Non-profoundly Autistic Individuals Admitted to a Specialized Psychiatric Inpatient Unit

PURPOSE

The prevalence of autism spectrum disorder (ASD) is currently estimated to be 1 in 36 children. While much is known about the impact of ASD on family and community functioning as well as treatment outcomes, less is known about a relatively new categorization of ASD, called "profound autism."

METHODS

The current study evaluated 14 consecutively admitted patients meeting criteria for profound autism to a specialized psychiatric inpatient and partial hospitalization program. We then selected 15 non-profoundly autistic youth admitted immediately before or after each profoundly autistic youth to serve as a comparison. Patient caregivers completed measures about parental stress and the severity and frequency of patient problem behavior, and patients participated in functional analyses of problem behavior and function-based treatment programs during their admission.

RESULTS

Results showed profoundly autistic youth spent an average of 14 more days admitted to the psychiatric unit, and they engaged in higher parent-reported severity and frequency of self-injurious and stereotypic behavior. Functional analysis results for profoundly autistic youth showed a higher occurrence of automatically reinforced problem behavior but otherwise similar results. As well, profoundly autistic youth showed a lower percentage reduction in problem behavior at the end of the psychiatric hospitalization than their non-profoundly autistic peers.

CONCLUSION

Profoundly autistic youth seem to require a high level of behavioral support, even after psychiatric hospitalization. Insurance companies and therapists need to recognize these challenges and invest sufficient resources to meet their treatment needs.

A conditional multi-label model to improve prediction of a rare outcome: An illustration predicting autism diagnosis

OBJECTIVE

This study aimed to develop a novel approach using routinely collected electronic health records (EHRs) data to improve the prediction of a rare event. We illustrated this using an example of improving early prediction of an autism diagnosis, given its low prevalence, by leveraging correlations between autism and other neurodevelopmental conditions (NDCs).

METHODS

To achieve this, we introduced a conditional multi-label model by merging conditional learning and multi-label methodologies. The conditional learning approach breaks a hard task into more manageable pieces in each stage, and the multi-label approach utilizes information from related neurodevelopmental conditions to learn predictive latent features. The study involved forecasting autism diagnosis by age 5.5 years, utilizing data from the first 18 months of life, and the analysis of feature importance correlations to explore the alignment within the feature space across different conditions.

RESULTS

Upon analysis of health records from 18,156 children, we are able to generate a model that predicts a future autism diagnosis with moderate performance (AUROC=0.76). The proposed conditional multi-label method significantly improves predictive performance with an AUROC of 0.80 (p < 0.001). Further examination shows that both the conditional and multi-label approach alone provided marginal lift to the model performance compared to a one-stage one-label approach. We also demonstrated the generalizability and applicability of this method using simulated data with high correlation between feature vectors for different labels.

CONCLUSION

Our findings underscore the effectiveness of the developed conditional multi-label model for early prediction of an autism diagnosis. The study introduces a versatile strategy applicable to prediction tasks involving limited target populations but sharing underlying features or etiology among related groups.

Results from a Pilot Randomized Controlled Trial of a Single-Session Growth-Mindset Intervention for Internalizing Symptoms in Autistic Youth

Autistic youth experience elevated rates of co-occurring internalizing symptoms. Interventions to treat internalizing symptoms in autistic youth are almost uniformly costly and time-intensive, blunting dissemination of intervention and highlighting the need for scalable solutions. One promising option is a relatively new class of evidence-based treatments, single-session interventions (SSIs), however, no study has examined SSIs for depression symptoms in autistic youth. Participants included 40 autistic adolescents ranging in age from 11 to 16 (Mage = 14.22, Nmale = 32). Eligible youth who agreed to participate were randomized to either the active intervention (Project Personality), or an active control designed to mimic supportive therapy. Participants and their caregiver completed questionnaires immediately before, after, and three months post intervention. All participants completed the intervention independently and largely reported enjoying it. The intervention was delivered with 100% fidelity. Findings demonstrated improvements in perceived primary control, malleability of personality, and social competence relative to the active control group immediately post-intervention. Further, results revealed improvements in self-reported depression symptoms and parent reported emotional regulation at 3-month follow up. This study was the first to assess a GM-SSI designed to treat depression symptoms in autistic adolescents. Results indicated improvements in perceived control immediately post-intervention and downstream improvements in depression. Nonetheless, we did not find improvements in symptoms of anxiety, suggesting that autistic adolescents may require modifications to the intervention to maximize benefit. Findings demonstrate the utility of GM-SSI for internalizing symptoms for autistic youth and hold considerable promise as a low-intensity and scalable intervention.

Profound Autism: An Imperative Diagnosis

Profound autism refers to a subset of individuals with autism spectrum disorder who have an intellectual disability with an intelligence quotient less than 50 and minimal-to-no language and require 24-hour supervision and assistance with activities of daily living. The general pediatrician will invariably work with autistic children across the spectrum and will likely encounter youth with profound autism. Awareness of profound autism as a real entity describing autistic children with concomitant intellectual disability and language impairment who require 24-hour care is the first step in developing a solid pediatric home for these youth.

Emotion regulation and emotion dysregulation in children and adolescents with Autism Spectrum Disorder: A meta-analysis of evaluation and intervention studies

Children and adolescents with Autism Spectrum Disorder (ASD) often experience challenges in emotion regulation (ER) and emotion dysregulation (ED) which can interfere with their adaptive functioning. This study aimed to systematically review and meta-analyze the evidence on ER/ED in children and/or adolescents with ASD, examining its relationship with the following variables: internalizing and externalizing symptoms, cognitive function and social skills, and the effectiveness of non-pharmacological interventions addressing ER difficulties. Both electronic and manual searches were conducted to identify potential studies. Fifty-five studies were included in the meta-analysis. A statistically significant between-group difference was found, suggesting greater ER/ED challenges in the ASD group. Also, the ASD group showed more maladaptive ER strategies and fewer adaptive ER strategies compared to the non-ASD participants. Additionally, more severe ASD and poorer social skills were associated with greater ED and poorer ER skills, respectivelly. Furthermore, there was a significant correlation between internalizing symptomatology and both adaptive and maladaptive ER strategies. Studies of non-pharmacological interventions showed significant improvement in both ER and ED. These results imply that assessing ER/ED in children and adolescents with ASD should be part of the evaluation process, and it should also be a focal point for intervention in this population.

Predictors of Treatment Response to a Community-Delivered Group Social Skills Intervention for Youth with ASD

Group social skills interventions (GSSIs) are among the most commonly used treatments for improving social competence in youth with ASD, however, results remain variable. The current study examined predictors of treatment response to an empirically-supported GSSI for youth with ASD delivered in the community (Ntotal=75). Participants completed a computer-based emotion recognition task and their parents completed measures of broad psychopathology, ASD symptomatology, and social skills. We utilized generalized estimating equations in an ANCOVA-of-change framework to account for nesting. Results indicate differential improvements in emotion recognition by sex as well as ADHD-specific improvements in adaptive functioning. Youth with both co-occurring anxiety and ADHD experienced iatrogenic effects, suggesting that SDARI may be most effective for youth with ASD without multiple co-occurring issues. Findings provide important directions for addressing variability in treatment outcomes for youth with ASD.

Pain sensitivity and perceptual sensitivity are associated with severity of emotional dysregulation in children with ADHD: a cross-sectional analysis using the Temperament in Middle Childhood Questionnaire

PURPOSE

Nearly 50% of children with attention-deficit/hyperactivity disorder (ADHD) experience emotional dysregulation or sensory over-responsiveness; this study examines their association.

METHODS

This cross-sectional analysis (n = 124) used data from the Micronutrients for ADHD in Youth (MADDY) Study, which enrolled children aged 6-12 with ADHD and emotional dysregulation. Sensory responsiveness was assessed using two subscales from the factor-analyzed Temperament in Middle Childhood Questionnaire: Pain Sensitivity and Perceptual Sensitivity. Emotional dysregulation was assessed using the Emotional-Problems and Conduct-Problems subscales from the Strengths and Difficulties Questionnaire and a composite score from the Child & Adolescent Symptom Inventory-5. Multivariable linear regression measured the association of pain and perceptual sensitivity with the severity of emotional dysregulation.

RESULTS

In adjusted models, pain sensitivity was positively associated with Emotional Problems (β = 0.97; 95% CI: 0.52, 1.41; p < 0.0001), Conduct Problems (β = 0.83; 95% CI: 0.44, 1.21; p = 0.0001), and CASI-5 composite (β = 0.25; 95% CI: 0.16, 0.34; p < 0.0001). Perceptual sensitivity was positively associated with Emotional Problems (β = 0.75; 95% CI: 0.15, 1.35; p = 0.01) but not Conduct Problems (β = 0.27; 95% CI: -0.24, 0.77; p = 0.30) or CASI-5 composite (β = 0.12; 95% CI: -0.01, 0.24; p = 0.07).

CONCLUSION

Pain sensitivity was associated with the severity of emotional dysregulation in this ADHD sample. To better understand possible causal links, longitudinal studies are warranted.Implications for rehabilitationEmotional dysregulation and sensory over-responsiveness are both common in children with ADHD and contribute to added challenges in school and family life.Two types of sensory over-responsiveness, pain sensitivity and perceptual sensitivity, were associated with emotional dysregulation in children with ADHD in our study.Sensory over-responsiveness may be a modifiable treatment target.

Understanding the Families' Perceptions of Adapted Physical Activity for Individuals with Autism Spectrum Disorder through Metaphors

The aim of this study was to understand the perceptions, understanding and experiences of the families of individuals with autism spectrum disorder (ASD) related to adapted physical activity (APA), and their educators, through their use of metaphors. The research was based on systematic content analysis in the qualitative research model. The data were collected based on metaphors. The participants included 85 families of individuals with ASD attending private institutions operating in Istanbul and Ankara. The metaphors used by the families were examined under two headings: adapted physical activities, and educators. When the metaphors used to describe APA were examined, four themes emerged, education, emotion, support and development, and these themes were divided into the categories of guidance, skill, affection, and care. When the metaphorical perceptions of educators were examined, three themes emerged: education, emotion, and social adaptation. These were further categorized as experience, knowledge, entertainment, independence, happiness, and treatment. The metaphors showed that experiences in APA support increased self-confidence for individuals with autism spectrum disorder and support the social adaptation of individuals who have the opportunity to apply knowledge and experience. This research shows that families have positive perceptions of APA educators and their lessons.

The Strengths and Difficulties Questionnaire as a Valuable Screening Tool for Identifying Core Symptoms and Behavioural and Emotional Problems in Children with Neuropsychiatric Disorders

The Strengths and Difficulties Questionnaire (SDQ) is a worldwide questionnaire used for the early identification of behavioural/emotional symptoms in children and adolescents with neuropsychiatric disorders. Although its prognostic power has been studied, it has not yet been tested whether SDQ: (i) can identify pathognomonic symptoms across a variety of neurodevelopmental and neuropsychiatric disorders, (ii) can capture emotional and behavioural problems associated with the main diagnosis, as well as shared transdiagnostic dimensions, and (iii) can detect changes in symptomatology with age. The present study evaluated nearly 1000 children and adolescents overall with Global Developmental Delay (GDD), Intellectual Disability (ID), Language Disorder (LD), Specific Learning Disorder (SLD), Autism Spectrum Disorder (ASD), Attention Deficit/Hyperactivity Disorder (ADHD), Mood Disorder (MD), Anxiety Disorder (AD), and Eating Disorders (ED). We found that SDQ: (i) can identify the core symptoms in children with ASD, ADHD, MD, and AD via specific subscales; (ii) can capture the associated emotional and behavioural symptoms in children with LD, GDD, ID, SLD, and ED; and (iii) can detect changes in the symptomatology, especially for GDD, LD, ASD, ADHD, and AD. SDQ is also able to recognise the transdiagnostic dimensions across disorders. Our results underscore the potential of SDQ to specifically differentiate and identify behavioural/emotional profiles associated with clinical diagnosis.

Trait Anxiety in Individuals on the Autism Spectrum: a Systematic Review

Although anxiety is commonly researched in autism, the focus has predominantly been on anxiety disorders and not upon general levels of anxiousness or trait anxiety. This review summarises research investigating trait anxiety in autism. Systematic searches yielded 1099 records, with 23 studies meeting inclusion criteria. Study participants were mainly males from Western countries, with no representation of older adults or individuals with intellectual disability. All articles used self-report questionnaire trait anxiety measures. Anxiety measure psychometric details were absent in most studies, with 21 using subjective measures that are not validated for use in autism. Results showed higher trait anxiety scores in autism versus control groups, and correlations between trait anxiety scores and other study outcomes.

Inpatient Care Unit in Children and Adolescents With Autism Spectrum Disorder: Benefits, Difficulties, and Conditions of Hospitalization

ABSTRACT

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder that affects social interactions and behavior. The number of children and adolescents with ASD treated in mental health services has been growing in recent years. Knowing clinical and familial characteristics of hospitalized patients with ASD and multidisciplinary approach are crucial for children and adolescents mental health professionals. In this study, 253 Turkish children and adolescents, with and without ASD, treated in psychiatry inpatient care unit were examined. Applied approaches such as medical consultation areas, psychiatric management of mothers, and pharmacological treatment during hospitalization, were studied. In addition to familial and clinical characteristics of patients with ASD, the benefits and the hospitalization conditions were evaluated. Patients with ASD showed a higher tendency on having relatives with a psychiatric disorder than the patients without ASD. A significant difference was found in terms of age, sex, and intellectual functioning, whereas length of stay did not differ drastically. Also, suicide attempts were significantly higher in patients without ASD than in patients with ASD. This study eases the management of hospitalized ASD patients with giving important information of clinical and familial characteristics.

Consortium neuroscience of attention deficit/hyperactivity disorder and autism spectrum disorder: The ENIGMA adventure

Neuroimaging has been extensively used to study brain structure and function in individuals with attention deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) over the past decades. Two of the main shortcomings of the neuroimaging literature of these disorders are the small sample sizes employed and the heterogeneity of methods used. In 2013 and 2014, the ENIGMA-ADHD and ENIGMA-ASD working groups were respectively, founded with a common goal to address these limitations. Here, we provide a narrative review of the thus far completed and still ongoing projects of these working groups. Due to an implicitly hierarchical psychiatric diagnostic classification system, the fields of ADHD and ASD have developed largely in isolation, despite the considerable overlap in the occurrence of the disorders. The collaboration between the ENIGMA-ADHD and -ASD working groups seeks to bring the neuroimaging efforts of the two disorders closer together. The outcomes of case-control studies of subcortical and cortical structures showed that subcortical volumes are similarly affected in ASD and ADHD, albeit with small effect sizes. Cortical analyses identified unique differences in each disorder, but also considerable overlap between the two, specifically in cortical thickness. Ongoing work is examining alternative research questions, such as brain laterality, prediction of case-control status, and anatomical heterogeneity. In brief, great strides have been made toward fulfilling the aims of the ENIGMA collaborations, while new ideas and follow-up analyses continue that include more imaging modalities (diffusion MRI and resting-state functional MRI), collaborations with other large databases, and samples with dual diagnoses.

Assessment of improvement in anxiety severity for children with autism spectrum disorder: The matched correspondence analysis approach

INTRODUCTION

Clinical trials typically involve random assignment to treatment conditions. However, random assignment does not guarantee a lack of systematic variation in the outcomes, and application of covariation methods for multiple dependent measures requires complicated assumptions that are often not met.

METHODS

This study employed matched correspondence analysis (CA) for controlling systematic variation and handling multiple outcomes. One hundred nine children with autism spectrum disorder (ASD) were assessed for anxiety symptom severity across four studies, where participants were randomly assigned to either cognitive behavioral therapy (CBT) or treatment as usual or waitlist (TAU/WT). Matched CA is designed to optimally scale only the differences between baseline and posttreatment, rendering the systematic baseline carryover effects irrelevant.

RESULTS

Differences in treatment efficacy were observed. CBT showed treatment efficacy on anxiety severity and anxiety-related impairment relative to TAU/WT, after the control of baseline carryover effects.

CONCLUSION

This study provides a way to control systematic variation between groups at the outset of treatment trials and is expected to provide a novel pathway to more proper assessment of treatment efficacy for children with ASD and anxiety.

The relationship between social and academic outcomes and anxiety for children and adolescents on the autism spectrum: A systematic review

Anxiety is the most common co-occurring condition in children on the autism spectrum but the potential impacts of anxiety on social and academic outcomes of children on the autism spectrum have not been systematically examined. In this review, 50 studies were identified that explore the relationship between anxiety and scores on social or academic measures in children on the autism spectrum. Social competence was frequently measured, and the findings of these studies were mixed. While other social constructs have received little attention, associations were found between anxiety and victimisation, and anxiety and social relationships. Only three studies focused on the impact of anxiety on scores on academic measures, highlighting the need for further research in this area. Anxiety was most frequently measured using subscales from broader behavioural instruments, which may not capture the range of anxiety symptoms of children on the autism spectrum. Future studies that include multi-informant methodologies and proportional representation of females and children with intellectual disability will further knowledge of the impact of anxiety in children on the spectrum.

Drug development for Autism Spectrum Disorder (ASD): Progress, challenges, and future directions

In 2017, facing lack of progress and failures encountered in targeted drug development for Autism Spectrum Disorder (ASD) and related neurodevelopmental disorders, the ISCTM with the ECNP created the ASD Working Group charged to identify barriers to progress and recommending research strategies for the field to gain traction. Working Group international academic, regulatory and industry representatives held multiple in-person meetings, teleconferences, and subgroup communications to gather a wide range of perspectives on lessons learned from extant studies, current challenges, and paths for fundamental advances in ASD therapeutics. This overview delineates the barriers identified, and outlines major goals for next generation biomedical intervention development in ASD. Current challenges for ASD research are many: heterogeneity, lack of validated biomarkers, need for improved endpoints, prioritizing molecular targets, comorbidities, and more. The Working Group emphasized cautious but unwavering optimism for therapeutic progress for ASD core features given advances in the basic neuroscience of ASD and related disorders. Leveraging genetic data, intermediate phenotypes, digital phenotyping, big database discovery, refined endpoints, and earlier intervention, the prospects for breakthrough treatments are substantial. Recommendations include new priorities for expanded research funding to overcome challenges in translational clinical ASD therapeutic research.

The Impact of Anxiety on the Participation of Children on the Autism Spectrum

Anxiety is common in children on the autism spectrum, however its impacts are not fully understood. Participation is an important outcome, linked to the health and wellbeing of children. This study examined the relationship between anxiety and participation using parent reports for 131 children on the autism spectrum, aged 6-13 years. Hierarchical multiple regressions explored child and family factors in relation to participation in Home and Community settings. Anxiety was a unique, significant predictor of the frequency of children's participation (but not involvement in activities) in both settings, when controlling for autism characteristics, communication skills and family income. Anxiety symptomatology may contribute to the less frequent participation of children on the autism spectrum in home and community activities.

Is cognitive inflexibility a missing link? The role of cognitive inflexibility, alexithymia and intolerance of uncertainty in externalising and internalising behaviours in young people with autism spectrum disorder

BACKGROUND

Internalising (anxiety and low mood) and externalising (aggressive or outburst behaviours, and irritability) difficulties are very common in autism spectrum disorder (ASD) across the life span, relatively stable over time and often associated with poorer quality of life. Understanding the cognitive mechanisms underlying internalising and externalising difficulties in ASD is essential for developing targeted supports and interventions. In the present study, we investigated established and less-researched cognitive factors hypothesised to contribute to internalising and/or externalising difficulties in ASD, namely cognitive inflexibility (CI), intolerance of uncertainty (IU) and alexithymia. Based on previous models and clinical experience, we hypothesised that IU would lead to internalising symptoms, with alexithymia contributing to this pathway, and that CI would have a direct effect on externalising behaviours and may indirectly contribute to internalising symptoms via increasing IU.

METHODS

Our sample consisted of 95 5- to 18-year-olds presenting to a specialist neurodevelopmental clinic and receiving a diagnosis of ASD. Parents/caregivers completed questionnaires assessing ASD symptomatology, internalising and externalising difficulties, CI, IU and alexithymia. Structural equation modelling was used to examine the hypothesised pathways and relationships between the main variables of interest.

RESULTS

Cognitive Inflexibility played a significant direct role in the pathway from ASD symptoms to externalising symptoms in ASD, and indirect role via IU in the pathway to internalising problems. Relationships between alexithymia and both internalising and externalising symptoms were weaker, with alexithymia predicting internalising difficulties via IU only.

CONCLUSIONS

The finding of a direct pathway from CI to externalising behaviours is novel, as is the indirect role of CI in internalising symptomatology. Of the three cognitive mechanisms examined, only CI significantly predicted externalising symptoms. Possible implications for interventions and supports targeting these cognitive processes in ASD are discussed.

The Role of Diagnostic Instruments in Dual and Differential Diagnosis in Autism Spectrum Disorder Across the Lifespan

The heterogeneity inherent in autism spectrum disorder (ASD) makes the identification and diagnosis of ASD complex. We survey a large number of diagnostic tools, including screeners and tools designed for in-depth assessment. We also discuss the challenges presented by overlapping symptomatology between ASD and other disorders and the need to determine whether a diagnosis of ASD or another diagnosis best explains the individual's symptoms. We conclude with a call to action for the next steps necessary for meeting the diagnostic challenges presented here to improve the diagnostic process and to help understand each individual's particular ASD profile.

Disorder-specific brain volumetric abnormalities in Attention-Deficit/Hyperactivity Disorder relative to Autism Spectrum Disorder

The overlap/distinctiveness between Attention-Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD) has been increasingly investigated in recent years, particularly since the DSM-5 allows the dual diagnosis of ASD and ADHD, but the underlying brain mechanisms remain unclear. Although both disorders are associated with brain volumetric abnormalities, it is necessary to unfold the shared and specific volume abnormalities that could contribute to explain the similarities and differences in the clinical and neurocognitive profiles between ADHD and ASD. In this voxel-based morphometry (VBM) study, regional grey matter volumes (GMV) were compared between 22 children with ADHD, 18 children with ASD and 17 typically developing (TD) children aged 8 to 12 years old, controlling for age and total intracranial volume. When compared to TD children or children with ASD, children with ADHD had a larger left precuneus, and a smaller right thalamus, suggesting that these brain abnormalities are specific to ADHD relative to ASD. Overall, this study contributes to the delineation of disorder-specific structural abnormalities in ADHD and ASD.

Comparative Effectiveness of Parent-Child Interaction Therapy for Children with and Without Autism Spectrum Disorder

Youth with autism spectrum disorder (ASD) often display disruptive behavior and noncompliance. Disruptive behavior in youth with ASD may limit their participation in educational and therapeutic activities and impact family functioning. Several evidence-based interventions are available for typically developing children, such as Parent-Child Interaction Therapy (PCIT). The current study examined the comparative effectiveness of PCIT for youth with ASD and without ASD. Results indicate that PCIT significantly improves parent-reported disruptive behavior in children with ASD at levels comparable to children without ASD. Additionally, improvements in ASD-related symptoms were noted for youth with ASD. These findings support the use of PCIT for children with ASD and provide clinicians with an evidence-based tool to address disruptive behavior in a wide spectrum of presenting children.

Atypical communication characteristics among clinic-referred youth with and without autism spectrum disorder: Stability and associations with clinical correlates

Atypical communication characteristics (ACCs), such as speech delay, odd pitch, and pragmatic difficulties, are common features of autism spectrum disorder (ASD) as are the symptoms of a wide range of psychiatric disorders. Using a simple retrospective method, this study aimed to better understand the relation and stability of ACCs with a broad range of psychiatric symptoms among large, well-characterized samples of clinic-referred children and adolescents with and without ASD. Youth with ASD had higher rates and a more variable pattern of developmental change in ACCs than the non-ASD diagnostic group. Latent class analysis yielded three ACC stability subgroups within ASD: Stable ACCs, Mostly Current-Only ACCs, and Little Professors. Subgroups exhibited differences in severity of ASD symptomatology, co-occurring psychiatric symptoms, and other correlates. Our findings provide support for the clinical utility of characterizing caregiver-perceived changes in ACCs in identifying children at risk for co-occurring psychopathology and other clinically relevant variables.

Cognitive Behavioral Treatments for Anxiety in Children With Autism Spectrum Disorder: A Randomized Clinical Trial

Importance

Anxiety is common among youth with autism spectrum disorder (ASD), often interfering with adaptive functioning. Psychological therapies are commonly used to treat school-aged youth with ASD; their efficacy has not been established.

Objective

To compare the relative efficacy of 2 cognitive behavioral therapy (CBT) programs and treatment as usual (TAU) to assess treatment outcomes on maladaptive and interfering anxiety in children with ASD. The secondary objectives were to assess treatment outcomes on positive response, ASD symptom severity, and anxiety-associated adaptive functioning.

Design, Setting, and Participants

This randomized clinical trial began recruitment in April 2014 at 3 universities in US cities. A volunteer sample of children (7-13 years) with ASD and maladaptive and interfering anxiety was randomized to standard-of-practice CBT, CBT adapted for ASD, or TAU. Independent evaluators were blinded to groupings. Data were collected through January 2017 and analyzed from December 2018 to February 2019.

Interventions

The main features of standard-of-practice CBT were affect recognition, reappraisal, modeling/rehearsal, in vivo exposure tasks, and reinforcement. The CBT intervention adapted for ASD was similar but also addressed social communication and self-regulation challenges with perspective-taking training and behavior-analytic techniques.

Main Outcomes and Measures

The primary outcome measure per a priori hypotheses was the Pediatric Anxiety Rating Scale. Secondary outcomes included treatment response on the Clinical Global Impressions-Improvement scale and checklist measures.

Results

Of 214 children initially enrolled, 167 were randomized, 145 completed treatment, and 22 discontinued participation. Those who were not randomized failed to meet eligibility criteria (eg, confirmed ASD). There was no significant difference in discontinuation rates across conditions. Randomized children had a mean (SD) age of 9.9 (1.8) years; 34 were female (20.5%). The CBT program adapted for ASD outperformed standard-of-practice CBT (mean [SD] Pediatric Anxiety Rating Scale score, 2.13 [0.91] [95% CI, 1.91-2.36] vs 2.43 [0.70] [95% CI, 2.25-2.62]; P = .04) and TAU (2.93 [0.59] [95% CI, 2.63-3.22]; P < .001). The CBT adapted for ASD also outperformed standard-of-practice CBT and TAU on parent-reported scales of internalizing symptoms (estimated group mean differences: adapted vs standard-of-practice CBT, -0.097 [95% CI, -0.172 to -0.023], P = .01; adapted CBT vs TAU, -0.126 [95% CI, -0.243 to -0.010]; P = .04), ASD-associated social-communication symptoms (estimated group mean difference: adapted vs standard-of-practice CBT, -0.115 [95% CI, -0223 to -0.007]; P = .04; adapted CBT vs TAU: -0.235 [95% CI,-0.406 to -0.065]; P = .01); and anxiety-associated social functioning (estimated group mean difference: adapted vs standard-of-practice CBT, -0.160 [95% CI, -0.307 to -0.013]; P = .04; adapted CBT vs TAU: -0.284 [95% CI, -0.515 to -0.053]; P = .02). Both CBT conditions achieved higher rates of positive treatment response than TAU (BIACA, 61 of 66 [92.4%]; Coping Cat, 47 of 58 [81.0%]; TAU, 2 of 18 [11.1%]; P < .001 for each comparison).

Conclusions and Relevance

In this study, CBT was efficacious for children with ASD and interfering anxiety, and an adapted CBT approach showed additional advantages. It is recommended that clinicians providing psychological treatments to school-aged children with ASD consider developing CBT expertise.

Hyperacusis in Children with Attention Deficit Hyperactivity Disorder: A Preliminary Study

The association between hyperacusis and developmental disorders such as autism spectrum disorders has been extensively reported in the literature; however, the specific prevalence of hyperacusis in attention deficit hyperactivity disorder (ADHD) has never been investigated. In this preliminary study, we evaluated the presence of hyperacusis in a small sample of children affected by ADHD compared to a control group of healthy children. Thirty normal hearing children with a diagnosis of ADHD and 30 children matched for sex and age were enrolled in the study. All children underwent audiological and multidisciplinary neuropsychiatric evaluation. Hearing was assessed using pure tone audiometry and immittance test; ADHD was diagnosed following the Diagnostic and Statistical Manual of Mental Disorder criteria. Hyperacusis was assessed through the administration of a questionnaire to parents and an interview with children. Hyperacusis was diagnosed in 11 children (36.7%) in the study group and in four children (13.3%) in the control group; this difference was statistically significant (p = 0.03). The preliminary results of this study suggest a higher presence of hyperacusis in children with attention deficit hyperactivity disorder compared to control children. More studies on larger samples are necessary to confirm these results.

A Pilot Study of Family-Based Exposure-Focused Treatment for Youth with Autism Spectrum Disorder and Anxiety

Anxiety is a common and impairing condition in youth with autism spectrum disorders (ASD). Evidence supports the use of cognitive behavioral therapy for treating anxiety in this population; however, available treatment protocols may be difficult to implement outside of research settings. The present study examined the efficacy of family-based exposure-focused treatment (FET) compared to a treatment as usual (TAU) control in 32 youth aged 6-17 years with ASD and co-occurring anxiety. Fourteen youth were randomized to FET, which included 12 face-to-face weekly therapy sessions lasing 45-55 min, while 18 youth completed the TAU control where engagement in psychotherapy or pharmacotherapy was at the discretion of the families. Results strongly supported FET with a 79% (versus 0% in TAU) response rate, 86% (versus 0% in TAU) remission in primary anxiety diagnosis, and large between-group effects on clinician-rated anxiety severity and most parent-rated domains of anxiety-related impairment. Among treatment responders, 2-month follow-up supported maintenance of gains. Overall, the study supported FET as a relatively brief intervention for the treatment of anxiety in youth with ASD, although further research is needed to replicate these findings and compare FET outcomes to more comprehensive interventions.

The Role of Diagnostic Instruments in Dual and Differential Diagnosis in Autism Spectrum Disorder Across the Lifespan

The heterogeneity inherent in autism spectrum disorder (ASD) makes the identification and diagnosis of ASD complex. We survey a large number of diagnostic tools, including screeners and tools designed for in-depth assessment. We also discuss the challenges presented by overlapping symptomatology between ASD and other disorders and the need to determine whether a diagnosis of ASD or another diagnosis best explains the individual's symptoms. We conclude with a call to action for the next steps necessary for meeting the diagnostic challenges presented here to improve the diagnostic process and to help understand each individual's particular ASD profile.

Development of a Composite Primary Outcome Score for Children with Attention-Deficit/Hyperactivity Disorder and Emotional Dysregulation

Objective: Study goals were to (1) provide a rationale for developing a composite primary outcome score that includes symptom severity for attention-deficit/hyperactivity disorder (ADHD) and emotional dysregulation, plus symptom-induced impairment; (2) demonstrate weighting methods to calculate the composite score using a sample of children diagnosed with ADHD and aggression; and (3) identify the optimal weighting method most sensitive to change, as measured by effect sizes. Methods: We conducted secondary data analyses from the previously conducted Treatment of Severe Childhood Aggression (TOSCA) study. Children aged 6-12 years were recruited through academic medical centers or community referrals. The composite primary outcome comprised the ADHD, oppositional defiant disorder, disruptive mood dysregulation disorder, and peer conflict subscales from the Child and Adolescent Symptom Inventory (CASI), a DSM (Diagnostic and Statistical Manual)-referenced rating scale of symptom severity and symptom-induced impairment. Five weighting methods were tested based on input from senior statisticians. Results: The composite score demonstrated a larger (Cohen's d) effect size than the individual CASI subscales, irrespective of the weighting method (10%-55% larger). Across all weighting methods, effect sizes were similar and substantial: approximately a two-standard deviation symptom reduction (range: -1.97 to -2.04), highest for equal item and equal subscale weighting, was demonstrated, from baseline to week 9, among all TOSCA participants. The composite score showed a medium positive correlation with the Clinical Global Impressions-Severity scores, 0.46-0.47 for all weighting methods. Conclusions: A composite score that included severity and impairment ratings of ADHD and emotional dysregulation demonstrated a more robust pre-post change than individual subscales. This composite may be a more useful indicator of clinically relevant improvement in heterogeneous samples with ADHD than single subscales, avoiding some of the statistical limitations associated with multiple comparisons. Among the five similar weighting methods, the two best appear to be the equal item and equal subscale weighting methods.

Assessing treatment efficacy by examining relationships between age groups of children with autism spectrum disorder and clinical anxiety symptoms: Prediction by correspondence analysis

INTRODUCTION

Autism spectrum disorders (ASD) are neurodevelopmental in nature and are frequently accompanied by anxiety. To fully assess treatment efficacy, we examined rates of anxiety symptom change by age groups following either cognitive behavioral therapy (CBT) or treatment as usual (TAU).

METHODS

One hundred sixty-three children with ASD and ASD-related anxiety symptoms were randomly assigned to either CBT or TAU. Utilizing prediction by correspondence analysis (CA), we evaluated the age effect (defined in three groups; ages 6-9, 10-12, and 13-16) and the changes in correlations between age and anxiety severity levels over the course of treatment.

RESULTS

Significantly greater anxiety symptom reduction was associated with CBT compared with TAU across the three age groups. Of particular note, the children ages 10-12 who received CBT showed the greatest improvement compared to all other groups. Late childhood, prior to adolescence, showed the best response to CBT for anxiety in ASD.

DISCUSSION

These findings suggest that treatment programs need to more closely address developmental factors within narrower bands of age groups. The present results are limited in their generalization to the CBT efficacy for a specific age band (ages 10-12). Longitudinal investigations are recommended to confirm whether the similar age group children who receive CBT experience the greatest benefit in reducing their ASD-related anxiety symptoms.

ADHD and ASD: distinct brain patterns of inhibition-related activation?

Attention-deficit/hyperactivity (ADHD) and autism spectrum (ASD) disorders often co-occur. In both cases, response inhibition deficits and inhibition-related atypical brain activation have been reported, although less consistently in ASD. Research exploring the overlap/distinctiveness between ADHD and ASD has significantly increased in recent years, but direct comparison of the inhibition-related neuronal correlates between these disorders are scarce in the literature. This study aimed at disentangling the shared and specific inhibitory brain dysfunctions in ASD and ADHD. Using functional magnetic resonance imaging (fMRI), brain activity was compared between children with ADHD, ASD and typically developing (TD) children aged 8-12 years during an inhibition stop-signal task, using stringent inclusion criteria. At the behavioural level, only children with ADHD exhibited inhibition deficits when compared with the TD group. Distinct patterns of brain activity were observed during successful inhibition. In children with ADHD, motor inhibition was associated with right inferior parietal activation, whereas right frontal regions were activated in children with ASD. Between-group comparisons disclosed higher middle frontal activation in the ASD group compared with the ADHD and the TD groups. Our results evidence different patterns of activation during inhibition in these two disorders, recruiting different regions of the fronto-parietal network associated to inhibition. Besides brain activity differences, behavioural inhibition deficits found only in children with ADHD further suggest that reactive inhibition is one of the core deficits in ADHD, but not in ASD. Our findings provide further evidence contributing to disentangle the shared and specific inhibitory dysfunctions in ASD and ADHD.

Bioactive Metabolites from Marine Ascidians: Future Treatment for Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a developmental disorder that influences communication and behavior. Numerous researches propose that genes can act together with manipulations from the environment to affect development in ways that lead to ASD. The broad range of issues facing people with ASD means that there is no single proper drug and treatment for ASD. Numerous shortcomings associated with the present conventional therapeutic strategies have forced researchers to venture into alternative natural sources for effective compounds. The marine environment has emerged as an alternate search environment due to its versatile conditions where organisms employ various biodefense mechanisms for their survival. Ascidians are an excellent source for unique bioactive compounds with nutritive and therapeutic content and it still holds credit for being an underused source from marine animals. Bioactive compounds isolated from ascidians have various commendable biomedical applications due to their unique chemical structures. The present chapter will focus on the potential of bioactive compounds derived from ascidians for the treatment of the neurologic disorder-ASD.

Treatment Gains from Early and Intensive Behavioral Intervention (EIBI) are Maintained 10 Years Later

This study reports outcome in adolescents with autism who in their childhood received Early and Intensive Behavioral Intervention (EIBI). Nineteen children (16 boys) who had received two years of EIBI starting at a mean age of 2-years-and-11-months were followed up, on average, 12 years later. Results showed the participants significantly increased their cognitive and adaptive standard scores during the two years of EIBI, and that these gains were maintained at follow-up, 10 years after the EIBI had ended. Participants also showed a significant reduction in autism symptoms between intake and follow-up. At follow-up, none of the participants had received any additional psychiatric diagnoses, and none were taking any psychotropic medication. Results indicate that treatment gains achieved in EIBI are maintained into adolescence.

Transitions, Suicidality, and Underappreciated Autism Spectrum Disorder in a High School Student

Alex is a 14-year-old Portuguese-American boy with a psychiatric history starting at age 5 who presents to your primary care practice after an insurance change.He was delivered prematurely at 32 weeks and diagnosed with congenital hypothyroidism at the age of 6 weeks and growth hormone deficiency at the age of 2 years; he is in active treatment for both. He otherwise met developmental milestones on time yet continues to have significant fatigue despite adequate sleep and vitamin D supplementation.His family history is remarkable for maternal anxiety, depression, suicidal thoughts, and previous attempted suicide, as well as anxiety, alcoholism, depression, and attention-deficit/hyperactivity disorder (ADHD) in the extended family.Alex has had multiple psychiatric diagnoses by sequential providers. He was diagnosed with generalized anxiety disorder and ADHD by 5 years of age, major depressive disorder by 11 years of age, persistent depressive disorder by 12 years of age, and ultimately disruptive mood dysregulation disorder because of severe and persistent temper outbursts associated with negative mood and behavioral dysregulation, leading to recurrent crisis evaluations. He has been psychiatrically hospitalized twice, in the fifth and seventh grade, for suicidal ideation (SI) and elopement from home, respectively. He recently completed a 2-week acute residential placement, during which no medication changes were made. Current medications include escitalopram 20 mg daily, guanfacine 1 mg 3 times daily, sustained release bupropion 100 mg twice daily, levothyroxine, vitamin D, and a weekly somatropin injection. He has not been able to tolerate psychostimulants or nonstimulant agents because of treatment-emergent SI.Now in the ninth grade, he continues to be easily distracted by peers, with impulsive behaviors and reduced self-regulation. Despite receiving special education services since the fifth grade, his academic performance has been poor, and he has limited motivation. Previous testing indicated average in an intelligence quotient test, with relative deficits in working memory compared with above average strength in fluid reasoning. He dislikes school and has few friends. He has always been noted to be "immature." He displays temper tantrums at home and school around transitions and behavioral expectations and has complained of feeling "different" and misunderstood by peers in addition to having difficulty reading social cues. His interests include acting and playing Fortnite and other video/computer games. His screen time is limited to 1 to 2 hr/d by the family.As the new clinician, you raise the possibility of undiagnosed autism spectrum disorder as a unifying/underlying diagnosis with his mother, who disagrees and does not consent to additional workup despite your recommendations. How would you proceed with next steps to best support your patient and his family in obtaining further clarifying evaluation?

Quantifying the Optimal Structure of the Autism Phenotype: A Comprehensive Comparison of Dimensional, Categorical, and Hybrid Models

OBJECTIVE

The two primary-seemingly contradictory-strategies for classifying child psychiatric syndromes are categorical and dimensional; conceptual ambiguities appear to be greatest for polythetic syndromes such as autism spectrum disorder (ASD). Recently, a compelling alternative has emerged that integrates both categorical and dimensional approaches (ie, a hybrid model), thanks to the increasing sophistication of analytic procedures. This study aimed to quantify the optimal phenotypic structure of ASD by comprehensively comparing categorical, dimensional, and hybrid models.

METHOD

The sample comprised 3,825 youth, who were consecutive referrals to a university developmental disabilities or child psychiatric outpatient clinic. Caregivers completed the Child and Adolescent Symptom Inventory-4R (CASI-4R), which includes an ASD symptom rating scale. A series of latent class analyses, exploratory and confirmatory factor analyses, and factor mixture analyses was conducted. Replication analyses were conducted in an independent sample (N = 2,503) of children referred for outpatient evaluation.

RESULTS

Based on comparison of 44 different models, results indicated that the ASD symptom phenotype is best conceptualized as multidimensional versus a categorical or categorical-dimensional hybrid construct. ASD symptoms were best characterized as falling along three dimensions (ie, social interaction, communication, and repetitive behavior) on the CASI-4R.

CONCLUSION

Findings reveal an optimal structure with which to characterize the ASD phenotype using a single, parent-report measure, supporting the presence of multiple correlated symptom dimensions that traverse formal diagnostic boundaries and quantify the heterogeneity of ASD. These findings inform understanding of how neurodevelopmental disorders can extend beyond discrete categories of development and represent continuously distributed traits across the range of human behaviors.

Effectiveness of the Stepping Stones Triple P group parenting program in reducing comorbid behavioral problems in children with autism

Children with autism spectrum disorders often exhibit comorbid behavioral problems. These problems have an impact on the severity of the core symptoms, the progression of the disorder as well as on the families’ quality of life. We evaluated the effectiveness of the Stepping Stones Triple P group parent training program as a supplementary intervention in the treatment of children with autism spectrum disorder. Therefore, we employed a single group repeated measures design and assessed child variables via parents’ and teachers’ judgments at four successive time points. The participants were parents of 24 children with autism spectrum disorder aged between 3.6 and 12 years. We found a significant reduction of comorbid behavioral problems in the children, primarily in the parents’ judgment at follow-up. Furthermore, a reduction of the autism spectrum disorder core symptoms emerged. The teachers’ judgment particularly revealed an improvement in children’s social relationships. Effect sizes were large ( ƞ2 ranging from 0.14 to 0.23). The findings demonstrate the effectiveness of the Stepping Stones Triple P as a supplementary intervention for reducing comorbid behavioral problems in the treatment of children with autism spectrum disorder. Higher parental self-efficacy and parental attributions, including parents’ ability to influence child problem behaviors, are discussed as important factors for the effectiveness of Stepping Stones Triple P.

Autism Spectrum Disorders and ADHD: Overlapping Phenomenology, Diagnostic Issues, and Treatment Considerations

PURPOSE OF REVIEW

Autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD) are both increasing in prevalence and commonly co-occur with each other. The goal of this review is to outline what has been published recently on the topics of ASD, ADHD, and the comorbid state (ASD+ADHD) with a particular focus on shared phenomenology, differential diagnosis, and treatment considerations.

RECENT FINDINGS

ASD and ADHD have shared genetic heritability and are both associated with shared impairments in social functioning and executive functioning. Quantitative and qualitative differences exist, however, in the phenotypic presentations of the impairments which characterize ASD and ADHD. For ASD interventions to be maximally efficacious, comorbid ADHD needs to be considered (and vice versa). The research on ASD and ADHD suggests some overlap between the two disorders yet enough differences to indicate that these conditions are sufficiently distinct to warrant separate diagnostic categories.

Autism severity, co-occurring psychopathology, and intellectual functioning predict supportive school services for youth with autism spectrum disorder

Supportive school services are a primary service modality for youth with autism spectrum disorder. Autism spectrum disorder, as well as co-occurring psychiatric symptoms and low intellectual abilities, interfere with academic achievement and therefore influence decisions about school services. Therefore, we examined the association of parent, teacher, and clinician ratings of autism spectrum disorder and co-occurring psychiatric symptom severity and intellectual functioning with school services. In total, 283 youth with autism spectrum disorder were assessed with clinical evaluation via the Autism Diagnostic Observation Schedule and parent and teacher versions of the CASI-4R ( Child and Adolescent Symptom Inventory). Full Scale Intelligence Quotient scores were obtained from case records. Clinical and teacher evaluations of autism spectrum disorder severity predicted services and were more strongly associated with school services than parent ratings. Teacher ratings were only associated with common school services (e.g. speech/language therapy, occupational therapy, and/or social skills training) frequency at medium and high levels of clinician-rated autism spectrum disorder severity. Higher IQ and parent-rated externalizing symptoms predicted lower likelihood of receiving school services, whereas internalizing symptoms were not predictive of school services. Autism spectrum disorder symptoms may overshadow externalizing and internalizing symptoms when considering school service supports. Results highlight the importance of evaluating autism spectrum disorder severity via multiple sources, especially in cases of unclear symptom presentation, when examining correlates of school services for youth with autism spectrum disorder.

Verbal Ability and Psychiatric Symptoms in Clinically Referred Inpatient and Outpatient Youth with ASD

Youth with autism spectrum disorder (ASD) experience high rates of psychiatric symptoms, but the relation between verbal ability and psychiatric symptoms is unknown. This study utilized a large sample of clinically referred inpatient and outpatient youth with ASD to compare psychiatric comorbidity between verbal and minimally-verbal youth, adjusting for nonverbal IQ, age, and ASD symptom severity. Results indicated that verbal youth were more likely to present with and meet clinical cutoffs for depression and oppositional defiant disorder symptoms, with greater impairment associated with depression. Youth in inpatient settings had greater symptom severity and impairment across almost all psychiatric comorbidities. These results present the most direct estimate to date of the association between verbal ability and psychiatric comorbidity in ASD.

Relation of Psychiatric Symptoms with Epilepsy, Asthma, and Allergy in Youth with ASD vs. Psychiatry Referrals

The present study aimed to characterize the association of psychopathology with the clinical correlates of epilepsy, asthma, and allergy within and between neurobehavioral syndromes. Participants were consecutively evaluated youth (6-18 years, 75 % male) with autism spectrum disorder (ASD; n = 589) and non-ASD outpatient psychiatry referrals (n = 653). Informants completed a background questionnaire (parents) and a psychiatric symptom severity rating scale (parents, teachers). Youth with ASD had higher rates of epilepsy and allergy but not asthma than psychiatry referrals, even when analyses were limited to youth with IQ ≥ 70. Somatic conditions evidenced variable associations with medical services utilization, educational interventions, family income, and maternal education. Youth with ASD with versus without epilepsy had more severe ASD social deficits (parents' ratings) and less severe ASD repetitive behaviors (teachers' ratings). Epilepsy was associated with more severe depression, mania, and schizophrenia symptoms in youth with ASD. Youth with allergy (psychiatry referrals only) had more severe anxiety and depression symptoms (parents' ratings) but less severe aggression (teachers' ratings) thus providing evidence of both context- and diagnostic-specificity. Youth with ASD versus non-ASD psychiatry referrals evidence a variable pattern of relations between somatic conditions and a range of clinical correlates, which suggests that the biologic substrates and psychosocial concomitants of neurodevelopmental disorders and their co-occurring somatic conditions may interact to produce unique clinical phenotypes.

Caregiver-Teacher Concordance of Challenging Behaviors in Children with Autism Spectrum Disorder Served in Community Mental Health Settings

Children with autism spectrum disorder (ASD) exhibit high rates of challenging behaviors that impair functioning and represent the primary presenting problem in mental health (MH) services. Obtaining symptom reports from multiple informants is critical for treatment planning. This study evaluated caregiver-teacher concordance of ratings of the intensity of challenging behaviors in children with ASD receiving MH services, and identified child clinical factors associated with concordance. This sample included 141 children (M = 9.07 years), their caregivers, and teachers. Caregiver-teacher concordance of challenging behaviors was low and impacted by the degree and type of child psychiatric comorbidity. Findings support need for increased attention to the range of psychiatric problems children with ASD present to tailor treatment recommendations and service delivery.

Parent-Reported Developmental Regression in Autism: Epilepsy, IQ, Schizophrenia Spectrum Symptoms, and Special Education

Examined the psychiatric and clinical correlates of loss of previously acquired skills (regression) as reported by parents of youth with autism spectrum disorder (ASD). Study sample comprised 6- to 18-year old (N = 213) children and adolescents with ASD. Parents reported regression in 77 (36%) youth. A more homogeneous subgroup with regression between 18 and 36 months (n = 48) had higher rates of intellectual disability, epilepsy, and special education, more socially restrictive educational settings, and more severe ASD communication deficits and schizophrenia spectrum symptoms than non-regressed youth (n = 136). Similar results were obtained for a more inclusive definition of regression (n = 77). A brief parent report of developmental regression may be a useful clinical indicator of later general functioning.

EDUTEA: A DSM-5 teacher screening questionnaire for autism spectrum disorder and social pragmatic communication disorder

Teacher's reports about child psychopathology are often useful because they make it possible to compare children's development within their normative peer group. The EDUTEA questionnaire aims to provide clinicians and researchers with a brief tool that can be used to screen autism spectrum disorders and social communication disorders in school settings. Method: It was designed according to DSM-5 criteria and validated in a sample of 2,660 Spanish schoolers. Results: The EDUTEA showed a two-factor structure with high internal reliability: Social communication impairments (α=.95) and Restricted behaviour patterns (α=.93). The ROC curve showed that the area under the curve was highly predictive (.90). We propose using a cut-off score of 10, which gives high values of sensitivity (87%), specificity (91.2%) and positive predictive value (.87). Moderate correlations were found with the severity score of the Autism Diagnostic Observation Schedule (ADOS-2) and the child pragmatic competence. Conclusions: The EDUTEA could be useful in ASD screening protocols in schools.

Trait and Ability Emotional Intelligence in Adolescents With and Without Autism Spectrum Disorder

Social-emotional impairments are considered core symptoms of Autism Spectrum Disorder (ASD). Although numerous interventions have been developed to remediate the social deficits in children with ASD, few have been designed to meet the needs of youth. Given research demonstrating relations between emotional intelligence (EI) and social outcomes in adults with Asperger Syndrome (AS), the current study examined both trait and ability EI to elucidate the nature of the EI strengths and impairments in youth with and without ASD. Twenty-five adolescents with ASD and 25 adolescents without ASD aged 13 to 17 years completed measures of ability and trait EI. Findings suggest that aspects of both trait and ability EI were significantly weaker in adolescents with ASD compared with typically developing adolescents. Implications, limitations, and future research are discussed.

Informant discrepancy defines discrete, clinically useful autism spectrum disorder subgroups

BACKGROUND

Discrepancy between informants (parents and teachers) in severity ratings of core symptoms commonly arise when assessing autism spectrum disorder (ASD). Whether such discrepancy yields unique information about the ASD phenotype and its clinical correlates has not been examined. We examined whether degree of discrepancy between parent and teacher ASD symptom ratings defines discrete, clinically meaningful subgroups of youth with ASD using an efficient, cost-effective procedure.

METHODS

Children with ASD (N = 283; 82% boys; M_age  = 10.5 years) were drawn from a specialty ASD clinic. Parents and teachers provided ratings of the three core DSM-IV-TR domains of ASD symptoms (communication, social, and perseverative behavior) with the Child and Adolescent Symptom Inventory-4R (CASI-4R). External validators included child psychotropic medication status, frequency of ASD-relevant school-based services, and the Autism Diagnostic Observation Schedule (ADOS-2).

RESULTS

Four distinct subgroups emerged that ranged from large between-informant discrepancy (informant-specific) to relative lack of discrepancy (i.e. informant agreement; cross-situational): Moderate Parent/Low Teacher or Low Parent/Moderate Teacher Severity (Discrepancy), and Moderate or High Symptom Severity (Agreement). Subgroups were highly distinct (mean probability of group assignment = 94%). Relative to Discrepancy subgroups, Agreement subgroups were more likely to receive psychotropic medication, school-based special education services, and an ADOS-2 diagnosis. These differential associations would not have been identified based solely on CASI-4R scores from one informant.

CONCLUSIONS

The degree of parent-teacher discrepancy about ASD symptom severity appears to provide more clinically useful information than reliance on a specific symptom domain or informant, and thus yields an innovative, cost-effective approach to assessing functional impairment. This conclusion stands in contrast to existing symptom clustering approaches in ASD, which treat within-informant patterns of symptom severity as generalizable across settings. Within-child variability in symptom expression across settings may yield uniquely useful information for characterizing the ASD phenotype.

Callous-unemotional traits moderate executive function in children with ASD and ADHD: A pilot event-related potential study

•

Children with ASD and ADHD show varied and heterogeneous executive function (EF) profiles.

•

Typical or enhanced EF has been demonstrated in individuals with callous-unemotional (CU) traits.

•

We investigated the effect of CU traits on event-related potential (ERP) responses during a cued continuous performance test (CPT-OX) in children with ASD, ADHD and co-occurring ASD + ADHD.

•

Children with ASD and high CU traits showed better conflict monitoring compared to children with ASD and low CU traits.

•

Increased CU traits may be associated with cognitive strengths in children with ASD.

Attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are associated with varied executive function (EF) difficulties. Callous-unemotional (CU) traits, a proposed antecedent of adult psychopathy, are often associated with intact or enhanced EF. Here we test whether CU traits may therefore modulate EF in ASD and ADHD, in which EF is typically impaired. We collected CU traits and measured event-related potentials (ERPs) that index EF during a cued-continuous performance test (CPT-OX) in boys with ASD, ADHD, comorbid ASD + ADHD and typical controls. We examined attentional orienting at cues (Cue-P3), inhibitory processing at non-targets (NoGo-P3) and conflict monitoring between target and non-target trials (Go-N2 vs. NoGo-N2). In children with ASD, higher CU traits were associated with an enhanced increase in N2 amplitude in NoGo trials compared to Go trials, which suggests relatively superior conflict monitoring and a potential cognitive strength associated with CU traits. The results emphasise the importance of considering the effects of co-occurring traits in the assessment of heterogeneity of EF profiles in neurodevelopmental disorders.

Comprehensive Psychometric Analysis of the Eyberg Child Behavior Inventory in Children with Autism Spectrum Disorder

Many assessment measures have only been validated for one specific diagnostic population, which is costly and reduces the clinical utility of assessments. The Eyberg Child Behavior Inventory (ECBI) is one popular measure designed to assess disruptive behavior problems in youth. The ECBI has sound psychometric properties in typically developing youth, but the factor structure has never been examined in children with autism spectrum disorder (ASD). Therefore, the current study conducted a comprehensive psychometric analysis of the ECBI in children with ASD. Retrospective data from a nationally representative sample was collected from 335 children with ASD ages 2-12 years old. A four factor solution was identified for this sample. Implications of these findings and directions for future research are discussed.
