Changes in the Administrative Prevalence of Autism Spectrum Disorders: Contribution of Special Education and Health from 2002–2008

This study examined changes in the administrative prevalence of autism spectrum disorders (ASD) in Utah children from 2002 to 2008 by record source (school and health), age (four, six, and eight), and special education classification. Prevalence increased 100% with 1 in 77 children aged eight identified with ASD by 2008. Across study years and age groups rates were higher when health and school data were combined with a greater proportion of cases ascertained from health. The proportion of children with both a health ASD diagnosis and a special education autism classification did not significantly change. Most children with an ASD health diagnosis did not have an autism special education classification. Findings highlight the growing health and educational impact of ASD.     

Autism Spectrum Disorders and Symptoms in Children with Molecularly Confirmed 22q11.2 Deletion Syndrome

In this study, we assessed the presence of autism spectrum disorders (ASD) among children with a confirmed 22q11.2 deletion (n = 98). The children’s caregivers completed screening measures of ASD behaviors, and for those whose scores indicated significant levels of these behaviors, a standardized diagnostic interview (Autism Diagnostic Interview-Revised; ADI-R) was administered. Results demonstrated that over 20% of children (n = 22) were exhibiting significant levels of autism spectrum symptoms based on the screening measures. Based upon the ADI-R, 14 children qualified for a diagnosis of an ASD, and for 11 of those children a diagnosis of autism was most appropriate. These findings increase our knowledge of developmental disorders associated with the 22q11.2 deletion and point to avenues for future investigation.     

Social Network Changes Over the School Year Among Elementary School-Aged Children with and Without an Autism Spectrum Disorder

This study examined the stability of children’s social networks and friendship features over one academic school year. Differences in the social network salience between typically developing children, children with an autism spectrum disorder (ASD), and children with a non-ASD disability were explored. As a whole, social network salience increased for all students across the school year; however, children in the upper grades had higher social network salience as the school year progressed than those in the younger grades. Compared to children with a non-ASD disability and typically developing children, children with ASD had significantly lower social network salience and received significantly fewer friendship nominations and more non-preferred nominations across the school year. While these data suggest that children’s social networks and patterns of peer relationships are relatively stable over time, school-based interventions that foster social development and peer engagement are still needed for children with ASD.     

The Association Between Child Autism Symptomatology, Maternal Quality of Life, and Risk for Depression

Parents raising children with autism spectrum disorders (ASDs) have been shown to experience high levels of stress and report a lower quality of life. The current study examined the association between child autism symptomatology, mother’s quality of life, and mother’s risk for depression in a sample of 1,110 mothers recruited from a web-based registry of families with children with an ASD. Higher autism symptomatology and a greater number of co-occurring psychiatric disorders in the child were associated with an increased risk for current treatment of maternal depression and a lower maternal quality of life. The results highlight the importance of screening for depression, particularly in mothers of children with ASD and mental health and behavioral challenges.     

Head Circumference as an Early Predictor of Autism Symptoms in Younger Siblings of Children with Autism Spectrum Disorder

Siblings of children with autism have an increased risk for autism spectrum disorders (ASD). As children with autism often exhibit an atypical trajectory of head circumference (HC) growth, HC may be an indicator of vulnerability to autism. This study investigated whether infant siblings of children with ASD (n = 77) with an atypical trajectory of HC growth were more likely than those without an atypical HC trajectory to develop autism symptoms. Results showed that infants who had larger HC at 12 months, and whose HC growth rate decelerated more rapidly between 12 and 24 months were more likely to exhibit autism symptoms than infants with more typical HC trajectories. Among infant siblings of children with autism, atypical HC growth might alert pediatricians to provide screening and/or referral for further evaluation.     

The identification and measurement of autistic features in children with septo-optic dysplasia,optic nerve hypoplasia and isolated hypopituitarism

This study aimed to highlight the occurrence of autism spectrum disorders (ASDs) in children with septo-optic dysplasia (SOD) and optic nerve hypoplasia (ONH). A cross-sectional study was designed, including 28 children with SOD and 14 children with ONH. Clinician diagnosis of ASD was reported in 14 children. The Social Communication Questionnaire (SCQ) reported that 23 children met the cut-off point for ASD, and 9 children met the cut-off point for autism. Greater levels of intellectual disability and visual loss were reported in children with ASD in comparison to those without ASD, but, of the two, intellectual disability was a better predictor for ASD. The SCQ lost its sensitivity and specificity in children who had greater visual loss which highlights a requirement for a measure that is sensitive to visual loss. It is also recommended that children with SOD/ONH would benefit from routine screening for ASDs.     

Clinical Utility of Autism Spectrum Disorder Scoring Algorithms for the Child Symptom Inventory-4

Few studies examine the clinical utility of autism spectrum disorder (ASD) rating scales for screening referrals to child psychiatry clinics. Parents/teachers from Long Island, NY, completed the Child Symptom Inventory-4, a DSM-IV-referenced rating scale for 6- to 12-year-old clinical referrals with an ASD (N = 317) or nonASD psychiatric (N = 191) diagnosis. Two separate groups of children attending public school, regular education classes in the same geographic area were also rated by their parents (N = 446) and teachers (N = 464). Stepwise forward regression generated a scoring algorithm based on a subset of all CSI-4 items that best differentiated ASD from nonASD children. ROC analyses indicated high levels of sensitivity/specificity for recommended ASD cutoff scores for parent and teacher ratings.     

Kata techniques training consistently decreases stereotypy in children with autism spectrum disorder

The effects of 14 weeks of Kata techniques training on stereotypic behaviors of children with autism spectrum disorders (ASD) were investigated. The study included 30 eligible (diagnosed ASD, school age) children with ages ranging from 5 to 16 years whom they assigned to an exercise (n=15) or a no-exercise control group (n=15). Participants of the exercise group received Kata techniques instruction four times per week for 14 weeks (56 sessions). Stereotypy was assessed at baseline (pre-intervention), week 14 (post-intervention), and at one month follow up in both groups. Results showed that Kata techniques training significantly reduced stereotypy in the exercise group. Following participation in Kata techniques training, stereotypy decreased from baseline levels by a M of 42.54% across participants. Interestingly, after 30 days of no practice, stereotypy in the exercise group remained significantly decreased compared to pre-intervention time. The participants of the control group did not show significant changes in the stereotypy. Teaching martial arts techniques to children with ASD for a long period of time consistently decreased their stereotypic behaviors.     

Impact of Cognitive Behavioral Therapy on Observed Autism Symptom Severity During School Recess: A Preliminary Randomized,Controlled Trial

This study compared cognitive behavioral therapy (CBT) and treatment-as-usual (TAU) in terms of effects on observed social communication-related autism symptom severity during unstructured play time at school for children with autism spectrum disorders (ASD). Thirteen children with ASD (7–11 years old) were randomly assigned to 32 sessions of CBT or community-based psychosocial treatment (TAU) for 16 weeks. The CBT program is based on the memory retrieval competition model and emphasizes the development of perspective-taking through guided behavioral experimentation supplemented with reflective Socratic discussion and supported by parent training and school consultation to promote generalization of social communication and emotion regulation skills. Trained observers blind to treatment condition observed each child during recess on two separate days at baseline and again at posttreatment, using a structured behavioral observation system that generates frequency scores for observed social communication-related autism symptoms. CBT outperformed TAU at posttreatment on the frequency of self-isolation, the proportion of time spent with peers, the frequency of positive or appropriate interaction with peers, and the frequency of positive or appropriate peer responses to the target child (d effect size range 1.34–1.62). On average, children in CBT were engaged in positive or appropriate social interaction with peers in 68.6 % of observed intervals at posttreatment, compared to 25 % of intervals for children in TAU. Further investigation of this intervention modality with larger samples and follow-up assessments is warranted.     

Public Stigma of Autism Spectrum Disorder at School: Implicit Attitudes Matter

This study examines the public stigma of children with autism spectrum disorder (ASD) by their school-aged peers, focusing on both explicit and implicit attitudes. The twofold aims were to provide a broader picture of public stigma and to explore age-related changes in attitudes. Students completed an explicit measure of the public stigma and an implicit measure of attitudes after watching a video displaying children with ASD vs. typically developing (TD) children. Both measures showed more negative perceptions towards children with ASD compared to TD children. However, while explicit attitudes improved with age, implicit attitudes remained constantly negative. This finding suggests that both explicit and implicit attitudes should be considered when promoting an inclusive climate at school.

     

Epidemiological study on the involvements of environmental factors and allergy in child mental health using the Autism Screening Questionnaire

Although autism is now recognized as being very common (Buie et al., 2010) and as developing due to not only genetic but also environmental factors, there is insufficient epidemiological evidence on the relationship between autism and allergy. In this study, therefore, we attempted to clarify the association of environmental factors with autism and allergy using a population-based epidemiological study and to propose a newly developed screening method with improved validity by determining the relationship between ASD (autism spectrum disorders) subscales. We examined the association among autistic score from the Autism Screening Questionnaire (ASQ Japanese version), living environment factors, and allergic disease in 1407 children aged 3–5 years old. We recognized that children with higher ASD score have significantly higher prevalence of nasal allergy and associated with significantly factors of boy and first in terms of birth order and maternal smoking. In addition, nasal allergy were observed to be associated with “reciprocal social interaction”, “language and communication”, and “repetitive and stereotyped patterns of behaviors” as subscales of ASD. These results suggest that autism in children were closely related to allergy and environmental factors. Investigation of allergy symptoms in addition to subscale of ASD seem to enable more efficient screening of autism tendency at an earlier stage.     

Characterizing Community-Based Mental Health Services for Children with Autism Spectrum Disorders and Disruptive Behavior Problems

This study describes the characteristics of children with autism spectrum disorders (ASD) with disruptive behavior problems served in community-based mental health clinics, characterizes psychotherapy process and outcome, and examines differences between children with ASD and a non-ASD comparison group. Results indicate that children with ASD served in this setting are high functioning and diagnostically complex. Certain research-based behavioral and cognitive behavioral psychotherapeutic strategies were observed frequently, while parent training strategies and active teaching strategies were observed less frequently. The intensity or thoroughness with which strategies were pursued was relatively low. Outcome analyses indicate improvement in child symptoms and family functioning. Treatment delivery and outcome were similar for children with and without ASD. These findings represent the first detailed observational data characterizing community-based mental health services for children with ASD.     

Screening for autism spectrum disorders in adult psychiatric out-patients: a preliminary report

OBJECTIVE: To estimate the prevalence of autism spectrum disorders (ASD) among adult psychiatric out-patients; to evaluate the efficacy of a new brief screening questionnaire (ASDASQ). Method: 1323 adult psychiatric out-patients were screened by staff. Analysis of psychiatric records of patients (n = 66) scoring high on the ASDASQ yielded 31 patients with a suspected ASD. Twenty-two of these patients were clinically examined. Three psychometric aspects of the questionnaire were studied. RESULTS: Seventeen patients were found by clinical examination to have an ASD. Since two patients scoring low on the ASDASQ were known to have an ASD, at least 19 patients in this population (1.4%) had a definite ASD. Seventeen of the ASD patients had been previously diagnosed with other psychiatric disorders, most frequently schizophrenia (n = 5). Of patients attending a treatment centre for severe psychiatric disabilities (n = 499), 3.2% had an ASD. The ASDASQ showed good reliability across and within raters. Internal consistency was excellent. CONCLUSION: Adult psychiatric patients sometimes have undiagnosed autism spectrum disorders. The ASDASQ can be useful for screening.     

Autism Treatment Survey: Services Received by Children with Autism Spectrum Disorders in Public School Classrooms

The Autism Treatment Survey was developed to identify strategies used in education of children with autism spectrum disorders (ASD) in Georgia. Respondents of the web-based survey included a representative sample of 185 teachers across the state, reporting on 226 children with ASD in grades preschool-12th. The top five strategies being used in Georgia (Gentle Teaching, sensory integration, cognitive behavioral modification, assistive technology, and Social Stories^TM) are recognized as lacking a scientific basis for implementation. Analysis revealed the choice of strategies varied by grade level and classroom type (e.g., general education, special education). Results highlight clear implications for preservice and inservice educator training, and the need for continued research to document evidence-based strategy use in public schools for students with ASD.     

Treatment of Seizure Disorders and EEG Abnormalities in Children with Autism Spectrum Disorders

The treatment of seizure disorders EEG epileptiform abnormalities without epilepsy in children with autism spectrum disorders (ASD) is considered within the context of the relationship of epilepsy and epileptiform disorders to language, behavior, and cognition. There is an increased prevalence of both epilepsy and abnormal potentially epileptogenic activity in children with ASD. Anecdotal evidence suggests that the use of anticonvulsants to treat epileptiform discharges thought to be producing dysfunction in selected aspects of cognition, language, or behavior makes a positive difference in a subgroup of children with ASD, but there is inadequate evidence on which to base specific recommendations. There is, at present, no scientific justification for considering epilepsy surgery in children with ASD in the absence of intractable clinical seizures.     

Stability of the Autism Diagnostic Interview—Revised from Pre-School to Elementary School Age in Children with Autism Spectrum Disorders

This study examined the stability of scores on the ADI-R from pre-school to elementary school age in children with autism spectrum disorders (ASD). Participants were 35 children who, at T1, all had a clinical diagnosis of ASD. On initial assessment (mean age 3.5 years; SD 0.6 years), all met ADI-R algorithm criteria for autism. ADI-R assessments were repeated at follow up (FU; mean age 10.5 years; SD 0.8 years). Changes in ADI-R total, domain and ADI-R algorithm item scores were assessed. Twenty-eight children continued to score above the ADI-R cut-off for autism at FU, although significant decreases in ADI-R domain and item scores were also found. In conclusion while classification of children according to ADI-R criteria generally remained stable between pre-school and elementary school age, many children demonstrated significant improvements in symptom severity.     

Intensive Cognitive Behavioral Therapy for Anxiety Disorders in School-aged Children with Autism: A Preliminary Comparison with Treatment-as-Usual

Children with autism spectrum disorders (ASDs) frequently present with a comorbid anxiety disorder that can cause significant functional impairment, particularly at school. An intensive modular cognitive behavioral treatment (CBT) program was delivered to address anxiety, self-regulation, and social engagement in school and in the community. A particular emphasis was placed on increasing generalizability of coping skills and positive social behavior by involving school personnel in the treatment process. Children (7–11 years old) were randomly assigned to an immediate treatment condition (IT) that included 32 sessions of CBT (n = 7) or a 16-week treatment-as-usual (TAU) condition (n = 5). The CBT sessions emphasized behavioral experimentation and emotion regulation training as well as social coaching on increasing positive peer interactions. School observations and consultations were included in the treatment model. Independent evaluators blind to treatment condition conducted structured diagnostic interviews at baseline and post-IT/post-TAU. Post-treatment analyses showed that 71.4 % of the IT group had remitted from their primary anxiety disorder diagnosis as compared with none of the TAU group. In addition, an ANCOVA analysis conducted with baseline anxiety scores included as a covariate revealed a statistically significant difference by treatment group in anxiety severity favoring the IT group at post-treatment. The 32-session CBT program is an intensive approach for children with ASD and moderate-to-severe anxiety disorders that appears to yield a clinically significant impact on anxiety symptoms. The generalizability of coping skills may be enhanced by the inclusion of school-based treatment components due to the consistency of supports this permits across the child’s daily settings.     

Autism spectrum disorders: early detection, intervention, education, and psychopharmacological management.

Our understanding and treatment of children with autism have changed dramatically since Leo Kanner first formally documented the disorder in 1943. With reference to the historical context, this paper reviews recent research addressing 4 major issues: early detection, intervention, education, and psychopharmacological management of children with autism and related (autistic) spectrum disorders (hereafter, "autism"). We conclude from our review of the evidence that, in the absence of additional, more compelling data, the clinical usefulness of existing screening instruments remains questionable. However, the potential importance of such research is underscored by the clear benefits of early behavioural intervention: despite differences in orientation, outcomes for children with autism can be significantly enhanced with early intensive intervention. Although many questions remain (notably, What are the critical therapeutic components? For whom? For what domains of development? For what level of intensity and duration?), interventions shown to be effective are all carefully planned, engineered, monitored, and designed to target specific skill domains. Including children with autism in regular classes within the public school system poses several challenges, the most pressing of which is the large number of school personnel who need to be trained in evidence-based teaching and behavioural management practices. Finally, psychotropic drugs may help to reduce some symptoms, but they are neither curative nor a substitute for other forms of support and intervention.     

Therapist Perspectives on Community Mental Health Services for Children with Autism Spectrum Disorders

This mixed methods study examined therapist perspectives on serving children with autism spectrum disorders (ASD) in community mental health (CMH) clinics. One hundred therapists completed a survey about their experiences with this population and 17 participated in subsequent focus groups to clarify and expand survey results. Results indicate that CMH therapists serve many children with ASD for behavior or other psychiatric problems and perceive serving this population as challenging and frustrating due to their limited training. Therapists are highly motivated for comprehensive ASD training on ASD characteristics and intervention strategies. These data were used to tailor and package evidence-based intervention strategies for delivery in CMH services.
