Does Parental Mental Health Moderate the Association between Parenting Stress and Child Externalizing Behaviors Among Autistic Children?

Parents of autistic children experience significant parenting stress, which is prospectively associated with increases in child externalizing behaviors. However, family factors that place specific families at risk for experiencing the negative impacts of parenting stress on child externalizing behaviors have not been identified. The present study examined whether parental mental health moderates the association between parenting stress and child externalizing behaviors. Parents of 501 autistic children (Mage=5.16yrs) completed the Parenting Stress Index and Eyberg Child Behavior Inventory. Parents reported whether they had ever been diagnosed with a mental health disorder. Parenting stress, parental internalizing diagnosis, and parental externalizing diagnosis all independently predicted child externalizing behavior. However, parenting stress did not interact with any category of parental mental health diagnoses to predict child externalizing. Results implicate high levels of parenting stress as a risk factor for increased child behavior problems among autistic children across parental mental health statuses. Interventions aimed at reducing parenting stress may improve parent outcomes and prevent the development of child externalizing behaviors among families of autistic children.

Child maltreatment in autism spectrum disorder and intellectual disability: results from a population-based sample.

BACKGROUND: Children with developmental disabilities are at heightened risk for maltreatment. However, little is known regarding the prevalence of maltreatment among specific groups, such as autism spectrum disorder (ASD) and/or intellectual disability (ID). Information about maltreatment in these groups can aid in the development of supports and prevention strategies for vulnerable children and their families. METHODS: Using record linkage between the Department of Social Services (DSS) and the Autism and Developmental Disabilities Monitoring (ADDM) network, this study compares the prevalence and characteristics of maltreatment among children with ASD-only (n = 316), ASD and comorbid ID (ASD+ID; n = 291), ID-only (n = 1,280), and controls (n = 3,101). Behavioral correlates of maltreatment are examined. RESULTS: Controlling for demographic factors, this study found significantly higher odds of reported and substantiated maltreatment among children with ASD-only (odds ratio = 1.86 for reported, 1.51 for substantiated), ASD+ID (odds ratio = 2.35 for reported, 1.97 for substantiated), and ID-only (odds ratio = 2.45 for reported, 2.49 for substantiated) relative to a population control group, with large effects. In particular, children with ASD+ID and ID-only were between two and three times more likely to experience maltreatment. All groups were more likely to experience physical neglect, and children in the ASD+ID and ID-only groups were more likely to experience all forms of abuse. Children in the ASD-only group were more likely to experience physical abuse. Maltreated children in the ASD-only and ID-only groups experienced more cases of physical abuse and neglect, and were victimized by more perpetrators compared to other maltreated youth. Maltreatment was associated with higher likelihood of aggression, hyperactivity, and tantrums for children with ASD. CONCLUSIONS: Children with ASD and/or ID are at heightened risk for maltreatment. Empirically-supported assessment and intervention approaches for identifying and addressing traumatic stress related to maltreatment in ASD are urgently needed.

Sex/Gender Differences in Screening for Autism Spectrum Disorder: Implications for Evidence-Based Assessment.

Autism spectrum disorder (ASD) is diagnosed more often in boys than in girls; however, little is known about the nature of this sex/gender discrepancy or how it relates to diagnostic assessment practices. This study examined the performance of the Social Communication Questionnaire (SCQ) in screening for ASD among boys and girls. Data were drawn from the South Carolina Children's Educational Surveillance Study, a population-based study of ASD prevalence among children 8-10 years of age. Analyses were conducted using SCQ data from 3,520 children, with direct assessment data from 272 with elevated SCQ scores. A bifactor model based on the Diagnostic and Statistical Manual of Mental Disorders's (5th ed.) two ASD symptom domains fit the data well and performed slightly better for girls. In the general population sample, girls exhibited fewer social communication/interaction and restricted-repetitive behavior symptoms than boys. In the direct assessment sample, however, girls with ASD showed greater impairment in social communication/interaction than boys with ASD. Items pertaining to social communication/interaction problems at ages 4-5 were among the most diagnostically efficient overall and particularly for girls. Similarly, receiver operating characteristic analyses suggested that the SCQ performs adequately among boys and well among girls. Results support the use of the SCQ in screening for ASD but do not indicate sex/gender-specific cutoffs. Girls with ASD may exhibit pronounced intraindividual deficits in social communication/interaction compared to male peers with ASD and female peers without ASD. Although more research is needed, careful attention to social communication/interaction deficits around 4-5 years of age may be especially useful for assessing ASD in girls.

Behavioral Parent Training Engagement Among Young Children With Autism Spectrum Disorder.

The purpose of the current study was to examine engagement with Behavioral Parent Training (BPT) for families of children with Autism Spectrum Disorder (ASD) and assess openness to novel delivery formats for BPT (e.g., telehealth, group). Participants were caregivers of 501 children with ASD (ages 2-6) enrolled in the SPARK (Simons Foundation Powering Autism Research for Knowledge) online national registry. The study assessed: (1) rates of child disruptive behavior diagnoses, (2) engagement and satisfaction with BPT, (3) parent and child factors (e.g., diagnostic history), and (4) openness to novel delivery formats. Almost 25% of young children with ASD in this sample had disruptive behavior problems rising to the level of a diagnosis of ADHD or ODD and thus would benefit from BPT. However, only one third of these families had actually been referred to BPT. Families indicated high level of interest in participating in BPT, with a particular interest in Parent Child Interaction Therapy (PCIT) as well as novel delivery formats such as telehealth and group. Specific components of the therapy and delivery formats were indicative of parent satisfaction (e.g. groups, longer treatment sessions, longer treatment length). Specific parent and child characteristics were predictive of openness to novel formats (e.g. parental depression, more severe behavioral challenges, lower verbal skills). Results underscore the need for increased referrals and access to BPT programs the ASD population. Both parent and child characteristics are important for determining appropriate delivery formats.

Agreement of parent-reported cognitive level with standardized measures among children with autism spectrum disorder.

Assessing cognitive development is critical in clinical research of autism spectrum disorder (ASD). However, collecting cognitive data from clinically administered assessments can add a significant burden to clinical research in ASD due to the substantial cost and time required, and it is often prohibitive in large-scale studies. There is a need for more efficient, but reliable, methods to estimate cognitive functioning for researchers, clinicians, and families. To examine the degree to which caregiver estimates of cognitive level agree with actual measured intelligence/developmental scores and understand factors that may impact that agreement, 1,555 autistic individuals (81.74% male; age 18 months-18 years) were selected from a large cohort (Simons Foundation Powering Autism Research for Knowledge, SPARK). Results suggest that querying parents about recent testing results and developmental diagnoses can provide valid and useful information on cognitive ability. The agreement of parental estimates varied with age, measured cognitive ability, autistic traits, and adaptive skills. In the context of large-scale research efforts, parent-reported cognitive impairment may be a good proxy for categorical IQ range for survey-based studies when specific IQ scores are not available, circumventing the logistical and financial obstacles of obtaining neuropsychological or neurodevelopmental testing.

Neighborhood Disadvantage Associated With Blunted Amygdala Reactivity to Predictable and Unpredictable Threat in a Community Sample of Youth.

BACKGROUND: Childhood socioeconomic disadvantage is a form of adversity associated with alterations in critical frontolimbic circuits involved in the pathophysiology of psychiatric disorders. Most work has focused on individual-level socioeconomic position, yet individuals living in deprived communities typically encounter additional environmental stressors that have unique effects on the brain and health outcomes. Notably, chronic and unpredictable stressors experienced in the everyday lives of youth living in disadvantaged neighborhoods may impact neural responsivity to uncertain threat. METHODS: A community sample of children (N = 254) ages 8 to 15 years (mean = 12.15) completed a picture anticipation task during a functional magnetic resonance imaging scan, during which neutral and negatively valenced photos were presented in a temporally predictable or unpredictable manner. Area Deprivation Index (ADI) scores were derived from participants' home addresses as an index of relative neighborhood disadvantage. Voxelwise analyses examined interactions of ADI, valence, and predictability on neural response to picture presentation. RESULTS: There was a significant ADI × valence interaction in the middle temporal gyrus, anterior cingulate cortex, hippocampus, and amygdala. Higher ADI was associated with less amygdala activation to negatively valenced images. ADI also interacted with predictability. Higher ADI was associated with greater activation of lingual and calcarine gyri for unpredictably presented stimuli. There was no three-way interaction of ADI, valence, and predictability. CONCLUSIONS: Neighborhood disadvantage may impact how the brain perceives and responds to potential threats. Future longitudinal work is critical for delineating how such effects may persist across the life span and how health outcomes may be modifiable with community-based interventions and policies.

Pharmacy waste, fraud, and abuse in health care reform.

OBJECTIVE: To describe the new Medicare and Medicaid waste, fraud, and abuse provisions of the Affordable Care Act (H. R. 3590) and Health Care and Education Affordability Reconciliation Act of 2010 (H. R. 4872), the preexisting law modified by H. R. 3590 and H. R. 4872, and applicable existing and proposed regulations. SUMMARY: Waste, fraud, and abuse are substantial threats to the efficiency of the health care system. To combat these activities, the Department of Health and Human Services and Centers for Medicare & Medicaid Services promulgate and enforce guidelines governing the proper assessment and billing for Medicare and Medicaid services. These guidelines have a number of provisions that can catch even well-intentioned providers off guard, resulting in substantial fines. H. R. 3590 and H. R. 4872 augment preexisting waste, fraud, and abuse laws and regulations. This article reviews the new waste, fraud, and abuse laws and regulations to apprise pharmacists of the substantial changes affecting their practice. CONCLUSION: H. R. 3590 and H. R. 4872 modify screening requirements for providers; modify liability and penalties for the antikickback statute, federal False Claims Act, remuneration, and Stark Law; and create or extend auditing and management programs. Properly navigating these changes will be important in keeping pharmacies in compliance.

Young Adults with Autism Spectrum Disorder and the Criminal Justice System.

This study describes charges, outcomes, and recidivism in both the juvenile and adult criminal justice systems (CJS) for young adults aged 17 to 23 years with autism spectrum disorder (ASD; n = 606). Results are compared to individuals with ID (n = 1271) and a population control group (n = 2973). About 3% of individuals with ASD were charged with at least one offense by the time they reached young adulthood. Few differences were found in CJS involvement across groups. Young adults with ASD were not over represented in the CJS in general, and were less likely to be involved in the adult justice system than their peers. They received similar charges and outcomes and were as likely to reoffend as their peers.

Preventing elopement in children with autism spectrum disorder.

Reports of missing children with autism spectrum disorder (ASD) are common in the media, and elopement can lead to dire consequences. This study quantified the use of preventive measures that target elopement, plus identified child/family characteristics associated with elopement and the use of preventive measures. This cross-sectional study included 394 caregivers of children ages 2-17 years with ASD followed in an academic medical center's Developmental-Behavioral Pediatrics clinic. Details about elopement, preventive measure use, and sociodemographic characteristics were assessed via an investigator-designed, parent advocate-approved questionnaire, while pertinent clinical factors were extracted from patients' electronic health records. Two hundred and sixty-seven caregivers (68%) reported elopement by their child. Elopement risk was not associated with sociodemographic characteristics, nor with any specific comorbidity or neurobehavioral medication. Children with limited communication skills were more likely to have a history of elopement (OR 2.24, 95% CI 1.30-3.84; P = 0.004). The most common preventive measure used was lock(s) at top of doors (51%), while less than a quarter of families were using handicap permits, signs/visual markers, or tracking devices. Implementation of certain modifications was statistically associated with socioeconomic status and comorbidities of interest. In addition to supporting previous literature about the increased elopement risk in children with limited communication skills, this study is the first to reveal that caregiver use of numerous preventive measures varies widely. The associations noted with use of specific preventive measures can help guide recommendations for this dangerous comorbid symptom, and provide information needed for future studies to assess the efficacy of various preventive measures. Autism Res 2019, 12: 1139-1146. © 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Elopement, defined as leaving an area without permission and placing oneself in a potentially dangerous situation, is a behavior exhibited by many children with autism. There is little information about the use of various modifications that target elopement in the pediatric population. This study identifies child/family characteristics that were related to elopement and the use of modifications, and stresses the importance of counseling families of children with autism about elopement.

When Are We Sure? Predictors of Clinician Certainty in the Diagnosis of Autism Spectrum Disorder.

Differential diagnosis of autism spectrum disorder (ASD) is challenging, and uncertainty regarding a child's diagnosis may result in under-identification or prolonged diagnostic pathways. The current study examined diagnostic certainty, or how sure clinicians were that their diagnosis was accurate, among 478 toddler and preschool-aged children referred for possible ASD to academic medical specialty clinics. Overall, 60 percent of diagnoses were made with complete certainty. Clinicians were more certain when positively identifying ASD than ruling it out. Children presenting with a moderate (vs high or low) level of observable ASD symptoms were less likely to have a certain diagnosis. Further, clinicians rated less diagnostic certainty for older children, those with public insurance, and those with higher IQ and adaptive behavior abilities.

Pharmacotherapy of Autism Spectrum Disorder: Results from the Randomized BAART Clinical Trial.

The objective of this trial, Biomarkers in Autism of Aripiprazole and Risperidone Treatment (BAART), was to provide support and guidance for an evidence-based approach for the selection and monitoring of initial pharmacotherapy in patients with autism by assessing predictors of efficacy, tolerability, and safety. This randomized double-blind parallel-group study was conducted in three academic medical centers and a single private pediatric practice. Eighty children or adolescents (aged 6-17 yrs) with autistic disorder were enrolled, and 61 patients were randomized to the study drug. Of those patients, 51 completed the 10-week trial, and 31 completed an optional 12-week blinded extension phase. All patients were treated with 2 weeks of placebo before random assignment to receive aripiprazole (31 patients) or risperidone (30 patients) for 10 weeks. Sixteen placebo responders (20%) were excluded from further analysis. Drug dosing followed U.S. Food and Drug Administration (FDA) labeling, and weekly dosage adjustments were allowed until week 4; patients were then maintained on a fixed dose for 6 additional weeks. Safety, physical, and psychological assessments were recorded weekly or every 2 weeks. No significant differences in severity of illness between the aripiprazole and risperidone groups were noted at baseline. All patients significantly improved on the Aberrant Behavior Checklist-Irritability subscale after 1 week and continued for the remaining 9 weeks and the extension phase. Improvement was greatest in the risperidone group at every assessment period and was statistically significantly better than that in the aripiprazole group at weeks 3 and 6 (p<0.05). No dose-limiting adverse events occurred during the dose-titration period. Mean weight gain in the aripiprazole group was significantly less than that in the risperidone group at week 4 (0.62 vs 1.38 kg, p=0.033) and week 10 (1.61 vs 3.31 kg, p<0.001), but the difference became nonsignificant for the 31 patients completing the 3-month extension phase (4.36 vs 5.55 kg, p=0.26). Pharmacotherapy of patients with autism spectrum disorder resulted in behavioral improvement within 1 week and lasted at least 22 weeks. Weight gain occurred to a greater degree with risperidone than aripiprazole initially, but the differences became nonsignificant by the end of the trial. Our trial supports previous results of drug efficacy and safety in patients with autism spectrum disorder from other trials and extends the evidence-based support for choosing an FDA-approved drug for initial pharmacotherapy for autism spectrum disorder.

Prevalence and characteristics of children with autism-spectrum disorders.

PURPOSE: The purpose of this study was to determine the prevalence of autism spectrum disorders (ASD) and associated characteristics among 8-year-old children. METHODS: This is an ongoing active, population-based surveillance program conducted in South Carolina as part of the Centers for Disease Control and Prevention's Autism and Developmental Disabilities Monitoring Network. Cases from the state's first two study years (2000 and 2002) have been combined for analysis, resulting in surveillance of 47,726 children who are 8 years of age. RESULTS: A total of 295 children met criteria for ASD, yielding a prevalence of 6.2 per 1000. The racial distribution of cases was similar to that of 8-year-old children in the study area, with boys more commonly affected than girls (3.1:1). Seventy-nine percent of cases were served in special education, 36% of these under Autism classification. Analyses by gender showed differences in diagnostic criteria and intellectual functioning. Girls more often were cognitively impaired (IQ

Reported History of Developmental Regression and Restricted, Repetitive Behaviors in Children with Autism Spectrum Disorders.

OBJECTIVE: Previous research on developmental regression in youth with autism spectrum disorders (ASD) has often been limited by the definition, assessment, and methodology used to evaluate and describe regression. This study sought to overcome these limitations by examining the prevalence, timing, and correlates of documented cases of developmental regression in a large, epidemiological sample of youth with ASD. METHOD: Utilizing a population-based surveillance methodology, this study includes 862 youth with ASD identified through abstraction and clinician record review. RESULTS: Approximately 21% of the sample had developmental regression documented in their medical or educational records with the mean age of regression being 24.2 ± 14.3 months. Youth with ASD and a history of regression were more likely to have comorbid intellectual disability, a prior community diagnosis of ASD, and be eligible for educational services as a student with autism. Youth with a documented history of regression also had higher rates of restricted, repetitive behaviors, such as stereotyped speech, nonfunctional routines/rituals, and sensory interests. CONCLUSION: Results suggest that youth with a history of regression are not only more likely to have comorbid intellectual disability but are also are more likely to have been previously diagnosed with ASD in the community, suggesting that development regression may play an important role in identifying children who are at the risk for ASD and need evaluation. Higher rates of restricted, repetitive behaviors in youth with a documented history of regression may also provide important insights into the relationship between ASD and developmental regression.

Prevalence of Autism Spectrum Disorders Among Children With Intellectual Disability.

Autism spectrum disorders (ASD) often co-occur with intellectual disability (ID) and are associated with poorer psychosocial and family-related outcomes than ID alone. The present study examined the prevalence, stability, and characteristics of ASD estimates in 2,208 children with ASD and ID identified through the South Carolina Autism and Developmental Disabilities Network. The prevalence of ASD in ID was 18.04%, relative to ASD rates of 0.60%-1.11% reported in the general South Carolina population. Compared to children with ASD alone, those with comorbid ID exhibited increased symptom severity and distinct DSM-IV-TR profiles. Further work is needed to determine whether current screening, diagnostic, and treatment practices adequately address the unique needs of children and families affected by comorbid ASD and ID diagnoses.

Screening and direct assessment methodology to determine the prevalence of autism spectrum disorders.

PURPOSE: Findings from the Centers for Disease Control and Prevention-sponsored Autism and Developmental Disabilities Monitoring (ADDM) network suggest a growing prevalence of autism spectrum disorders (ASDs). The rigorous ADDM record review methodology has provided valuable insight into the epidemiology of autism spectrum disorder (ASD), but recent studies using alternative methods have reported significantly higher prevalence estimates. The South Carolina Children's Educational Surveillance Study (SUCCESS) was designed to determine ASD prevalence via population-based screening and direct assessment and to compare prevalence results to ADDM and administrative prevalence counts. This article provides an overview of the methods used for this study. METHODS: SUCCESS involved a novel (first in the United States) population-based screening approach combined with direct assessment to determine ASD prevalence. RESULTS: SUCCESS results will be compared to those obtained via records-based surveillance (ADDM) and administrative counts in the same population of children. This article describes the methods for developing and implementing SUCCESS and rationale for major decisions. Procedures used to maximize participation and accurately determine case status are discussed. Study results will be available in 2016. CONCLUSIONS: Accurate reporting of ASD prevalence is important to researchers, health care providers, policy makers, and families. This study will clarify the findings of various methods used to estimate ASD prevalence.

Age Differences in Emergency Department Visits and Inpatient Hospitalizations in Preadolescent and Adolescent Youth with Autism Spectrum Disorders.

This paper evaluated age differences in emergency department care and inpatient hospitalizations in 252 preadolescent and adolescent youth with autism spectrum disorders (ASDs; ages 9-18). Records from youth with ASDs were linked to acute care utilization records and were compared to a demographically similar comparison group of youth without ASDs (N = 1260). A particular focus was placed on utilization for psychiatric concerns and injuries or accidents. Results suggested that psychiatric care was more likely for youth with ASDs in both the preadolescent and adolescent cohorts versus comparison youth, with no significant differences between age cohorts. In contrast, results for the accident and injury categories suggested age-specific findings. Results suggest opportunities for prevention efforts for youth with ASDs.

Pilot Study and Review: Physiological Differences in BDNF, a Potential Biomarker in Males and Females with Autistic Disorder.

AIMS: There is a need for more biologic research in autistic disorder (AD) to determine if biomarkers exist that would be useful for correlating to symptom severity and/or clinical improvement during treatment. Given the fact that AD is 4 times more common in males than females, gender differences in physiological biomarkers may be present. One potential biomarker that has begun to be studied is brain-derived neurotropic factor (BDNF), a peptide involved in the regulation of neuronal cell survival, differentiation, and plasticity, and possessing an ability to influence neurotransmitter systems by modulating gene expression. This pilot study examined whether serum BDNF differed according to gender in children with AD and whether differences were associated with a behavioral phenotype or severity of illness. STUDY DESIGN: Data for this investigation were collected during the participants' baseline visit of an intervention study. Participants were males (n=29) and females (n=7), aged 5 to 12 years diagnosed with AD. Baseline serum BDNF concentration was determined for comparison to clinical ratings using an autism severity measure and the Pervasive Developmental Disorder-Behavior Inventory (PDD-BI). RESULTS: BDNF serum concentrations were higher in females (p<0.049). The baseline BDNF value corresponded significantly to hyperactivity in females (p<0.0002) but not in males. BDNF did not correlate with severity of disease in either gender. CONCLUSION: Although this is a small study, a better understanding of the central role of BDNF may provide insight into the pathophysiology of the disease and elucidate why gender differences exist in prevalence and behavioral phenotype of AD.

Potential impact of DSM-5 criteria on autism spectrum disorder prevalence estimates.

IMPORTANCE: The DSM-5 contains revised diagnostic criteria for autism spectrum disorder (ASD) from the DSM-IV-TR. Potential impacts of the new criteria on ASD prevalence are unclear. OBJECTIVE: To assess potential effects of the DSM-5 ASD criteria on ASD prevalence estimation by retrospectively applying the new criteria to population-based surveillance data collected for previous ASD prevalence estimation. DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional, population-based ASD surveillance based on clinician review of coded behaviors documented in children's medical and educational evaluations from 14 geographically defined areas in the United States participating in the Autism and Developmental Disabilities Monitoring (ADDM) Network in 2006 and 2008. This study included 8-year-old children living in ADDM Network study areas in 2006 or 2008, including 644 883 children under surveillance, of whom 6577 met surveillance ASD case status based on the DSM-IV-TR. MAIN OUTCOMES AND MEASURES: Proportion of children meeting ADDM Network ASD criteria based on the DSM-IV-TR who also met DSM-5 criteria; overall prevalence of ASD using DSM-5 criteria. RESULTS: Among the 6577 children classified by the ADDM Network as having ASD based on the DSM-IV-TR, 5339 (81.2%) met DSM-5 ASD criteria. This percentage was similar for boys and girls but higher for those with than without intellectual disability (86.6% and 72.5%, respectively; P < .001). A total of 304 children met DSM-5 ASD criteria but not current ADDM Network ASD case status. Based on these findings, ASD prevalence per 1000 for 2008 would have been 10.0 (95% CI, 9.6-10.3) using DSM-5 criteria compared with the reported prevalence based on DSM-IV-TR criteria of 11.3 (95% CI, 11.0-11.7). CONCLUSIONS AND RELEVANCE: Autism spectrum disorder prevalence estimates will likely be lower under DSM-5 than under DSM-IV-TR diagnostic criteria, although this effect could be tempered by future adaptation of diagnostic practices and documentation of behaviors to fit the new criteria.

High prescription drug use and associated costs among Medicaid-eligible children with autism spectrum disorders identified by a population-based surveillance network.

PURPOSE: We assessed medication use and associated costs among 8- and 15-year-old children with autism spectrum disorders (ASD) identified by the South Carolina Autism and Developmental Disabilities Monitoring (SCADDM) Network. METHODS: All Medicaid-eligible SCADDM-identified children with ASD from surveillance years 2006 and 2007 were included (n = 263). Children were classified as ASD cases when documented behaviors consistent with the DSM-IV-TR criteria for autistic disorder, Asperger disorder, or pervasive developmental disorder-not otherwise specified were present in health and education evaluation records. Medication and cost data were obtained by linking population-based and Medicaid data. RESULTS: All 263 SCADDM-identified children had Medicaid data available; 56% (n = 147) had a prescription of any type, 40% (n = 105) used psychotropic medication, and 20% (n = 52) used multiple psychotropic classes during the study period. Common combinations were (1) attention deficit hyperactivity disorder medications and an antihypertensive, antidepressant or antipsychotic; and (2) antidepressants and an antipsychotic. Multiple psychotropic classes were more common among older children. Both the overall distribution of the number of prescription claims and medication costs varied significantly by age. CONCLUSIONS: Results confirm that medication use in ASD, alone or in combination, is common, costly, and may increase with age.

The prevalence of youth with autism spectrum disorders in the criminal justice system.

Past surveys have reported high rates of youth with disabilities in the juvenile justice system, however, little research has examined the frequency with which youth with Autism spectrum disorders (ASD) are in contact with law enforcement. Using records linkage with the Department of Juvenile Justice and the South Carolina Law Enforcement Division and the South Carolina Autism and Developmental Disabilities Monitoring Program (SC ADDM), this study compares the frequency, type, and outcome of criminal charges for youth with ASD and non-ASD youth. Youth with ASD had higher rates of crimes against persons and lower rates of crimes against property. Youth with ASD were more likely to be diverted into pre-trial interventions and less likely to be prosecuted than comparison youth. When compared to the overall SC ADDM sample, charged youth were less likely to have comorbid intellectual disability.
