Parent-led cognitive behavioral therapy (CBT) is an efficient, promising form of therapy that may be well suited for autistic youth with anxiety disorders, though to date it has been minimally tested. In this study, 87 autistic youth (7 to 13 years old) with anxiety disorders and their parents were randomized to two forms of parent-led CBT in which parents led their child through a guided CBT workbook across 12 weeks: one with low therapist contact (four 30-minute telehealth calls), and one with standard therapist contact (ten 60-minute telehealth calls). Anxiety, functional impairment, and autism features significantly declined across therapy, without differences between groups.

Purpose: This study seeks to examine the relationship between anxiety-symptom severity and sleep behaviors in autistic children receiving cognitive behavioral therapy (CBT).

Methods: We conducted a secondary-data analysis from a sample of 93 autistic youth, 4 to 14 years, participating in 24 weeks of CBT. Clinicians completed the Pediatric Anxiety Rating Scale (PARS) and parents completed the Children's Sleep Habits Questionnaire, Abbreviated/Short Form (CSHQ-SF) at baseline, mid-treatment, post-treatment and 3 months post-treatment.

Article Synopsis
  • Autistic youth frequently experience anxiety and depression, but there are not many validated tools to assess these conditions specifically in this group.
  • The Revised Children's Anxiety and Depression Scale (RCADS) was tested on a group of treatment-seeking autistic youth and showed strong internal consistency for both the Parent and Child versions.
  • Findings suggest that the RCADS can be used reliably to measure internalizing symptoms in autistic youth, even though the correlation between child and parent scores was weak and some validity aspects were mixed.*

Anger outbursts (AO) are associated with severe symptoms, impairment and poorer treatment outcomes for anxious children, though limited research has examined AO in youth with co-occurring autism and anxiety disorders. This study examined AO in children with autism and anxiety by evaluating clinical characteristics, family accommodation, and changes in AO following anxiety-focused treatment. The sample comprised 167 youth with autism and anxiety enrolled in a multi-site randomized clinical trial comparing standard care CBT for anxiety, CBT adapted for youth with autism, and usual care.

Early intervention can help children learn language and improve social communication. However, many barriers, including the expense of services and an insufficient number of providers, prohibit families from accessing services when their children are young. We developed a comprehensive online program for caregivers of autistic children.

This trial examined stepped-care cognitive-behavioral treatment (CBT) among 96 autistic youth with co-occurring anxiety. Step 1 included an open trial of parent-led, therapist-guided bibliotherapy. Step 2 was family-based CBT for those who did not respond to Step 1 or maintenance for those who did.

There are currently at least 19 million children and adolescents in the United States with disorders of development (learning disorders, attention-deficit/hyperactivity disorder, intellectual disabilities, autism, motor incoordination/cerebral palsy, etc.) and only approximately 800 board-certified developmental-behavioral pediatricians (DBPs) practicing nationally. Given the astronomical mismatch between the number of children and adolescents with developmental disorders and the number of board-certified DBPs, developmental-behavioral pediatric consultations are likely the most inaccessible in all of medicine.

Angelman Syndrome (AS) is a neurodevelopmental disorder most commonly caused by the impaired expression of the maternal UBE3A gene on chromosome 15. Though anxiety has been identified as a frequently present characteristic in AS, there are limited studies examining anxiety in this population. Studies of anxiety in other neurodevelopmental disorders have found disorder specific symptoms of anxiety and age specific displays of anxiety symptoms.

Parents of children with autism spectrum disorder (ASD) may be at greater risk for developing antivaccine beliefs that lead to vaccine delays and/or refusals for their children. We investigated current parental vaccine hesitancy, parents' beliefs about causes of children's developmental delays, and children's vaccination histories among parents of children with ASD or non-ASD developmental delays. Data were analyzed from 89/511 parents (17.

Although norm-referenced scores are essential to the identification of disability, they possess several features which affect their sensitivity to change. Norm-referenced scores often decrease over time among people with neurodevelopmental disorders who exhibit slower-than-average increases in ability. Further, the reliability of norm-referenced scores is lower at the tails of the distribution, resulting in floor effects and increased measurement error for people with neurodevelopmental disorders.

Anxiety disorders affect up to 50% of individuals with autism spectrum disorder (ASD) and are significantly impairing to the person affected, as well as to their loved ones. Cognitive-behavioral therapy (CBT) has been established as the gold-standard treatment for anxiety disorders among typically developing youth and adults, and demonstrates similar efficacy among youth with high-functioning autism (HFA). Many CBT interventions utilize a "full-package" treatment approach to treat co-occurring anxiety in youth with ASD.

Fears persist despite compelling evidence refuting associations between vaccines and autism spectrum disorder (ASD). We compared vaccine hesitancy (VH) and beliefs about illness causes among parents of children in four groups: ASD, non-ASD developmental disorders, rheumatologic conditions, and the general pediatric population. VH was 19.

Objectives: To examine screening practices for autism spectrum disorder (ASD), subsequent referrals, and diagnostic outcomes within a large network of primary pediatric care practices.

Methods: Rates of ASD screening with the Modified Checklist for Autism in Toddlers (M-CHAT) at 18- and 24-month well-child visits were examined among 290 primary care providers within 54 pediatric practices between June 2014 and June 2016. Demographic, referral, and diagnostic data were abstracted from the medical records for all children who failed the M-CHAT (ie, score of ≥3) at either or both visits.

Parent satisfaction with neurodevelopmental evaluations may influence the pursuit of intervention. Parent satisfaction with a neurodevelopmental evaluation for toddlers at risk for autism (n = 257; 128 with autism) was examined using the Post-Evaluation Satisfaction Questionnaire, which collected quantitative and qualitative information. Fewer ethnic/racial minority than non-minority parents returned the questionnaire.

Truncating variants of the MAGEL2 gene, one of the protein-coding genes within the Prader-Willi syndrome (PWS) critical region on chromosome 15q11, cause Schaaf-Yang syndrome (SYS)-a neurodevelopmental disorder that shares several clinical features with PWS. The current study sought to characterize the neurobehavioral phenotype of SYS in a sample of 9 patients with molecularly-confirmed SYS. Participants received an assessment of developmental/intellectual functioning, adaptive functioning, autism symptomatology, and behavioral/emotional functioning.

Increased public awareness of autism spectrum disorders (ASD) and routine screening in primary care have contributed to increased requests for diagnostic ASD evaluations. However, given the scarcity of subspecialty autism diagnostic resources, overreferral of children suspected of having ASD may be contributing to long waiting lists at tertiary care autism centers and delaying diagnosis for those children who truly have ASD. To determine whether children are being excessively referred to ASD-specific diagnostic clinics, our objective was to determine the prevalence of true ASD diagnoses in children referred for diagnostic ASD evaluation.

This study investigated the accuracy of brief anxiety scales for non-treatment-seeking youth with autism spectrum disorder. In all, 54 youth (7-17 years; IQ: 67-158) with autism spectrum disorder and their parents completed (a) an expanded version of the Anxiety Disorders Interview Schedule-Child/Parent designed to capture typical and atypical fears and (b) brief scales of anxiety symptoms (Behavior Assessment Schedule for Children, Second Edition; Screen for Child Anxiety and Related Emotional Disorders; Negative Affective Self-Statement Questionnaire; Pediatric Anxiety Rating Scale). The results indicate that measures lacked adequate sensitivity and specificity, and the detection of atypical fears was particularly poor.
