Kalb, Luther G.; Holingue, Calliope; Pfeiffer, Danika; Reetzke, Rachel; Dillon, Emily; Azad, Gazi; Freedman, Brian; Landa, Rebecca – Autism: The International Journal of Research and Practice, 2021
A reliable autism spectrum disorder (ASD) diagnosis can occur as early as 18 months; however, the average age at diagnosis in the United States is over 2 years later. While there are numerous well-known barriers to seeking an ASD diagnosis, no research has examined if separation between a child's biological parents affects timing of ASD diagnosis…

Limberg, Katharina; Gruber, Karolin; Noterdaeme, Michele – Autism: The International Journal of Research and Practice, 2017
A long delay between the first registered symptoms of autism spectrum disorder and a final diagnosis has been reported. The reasons for this are the spare use of specialized autism instruments, missing clinical expertise, and the late referral to specialized centers in primary care. Previous studies recommending the Child Behavior Checklist 1.5-5…

Guttentag, Sara; Bishop, Somer; Doggett, Rebecca; Shalev, Rebecca; Kaplan, Megan; Dyson, Margaret; Cohen, Morgan; Lord, Catherine; Di Martino, Adriana – Autism: The International Journal of Research and Practice, 2022
Symptoms of autism spectrum disorder and attention-deficit/hyperactivity disorder often co-occur, challenging timely, and accurate diagnosis. We assessed the performance of three parent-report measures in discriminating autism spectrum disorder from attention-deficit/hyperactivity disorder without autism spectrum disorder (ADHD[subscritpt w/oASD])…

Baker, Bruce L.; Blacher, Jan – Journal of Mental Health Research in Intellectual Disabilities, 2015
Dual diagnosis of autism spectrum disorder (ASD) and behavior problems and/or mental disorders has become increasingly recognized and studied. Reported rates in samples of mixed-age youth with ASD are often above 70%, making this comorbidity more the rule than the exception. The present study compared rates of disruptive behavior disorder…

Fetal androgen exposure may be associated with autism spectrum disorder (ASD). We studied 1777 mother-child pairs in the prospective Odense Child Cohort. Prenatal androgen exposure was assessed by maternal 3rd trimester testosterone concentrations, maternal polycystic ovary syndrome (PCOS), and 3 months offspring anogenital distance. ASD traits…

Kawaoka, Naomi; Ohashi, Kei; Fukuhara, Satomi; Miyachi, Taishi; Asai, Tomoko; Imaeda, Masayuki; Saitoh, Shinji – Journal of Autism and Developmental Disorders, 2022
In March 2020, many schools were closed to prevent the spread of COVID-19 in Japan, and it is predicted that many children, especially those with neurodevelopmental disorders (NDDs), will be affected emotionally and behaviorally. Here, we examined the impact of school closures due to COVID-19 on school-aged children with NDDs using the Child…

The capacity of the Child Behavior Checklist 1½-5 (CBCL 1½-5) to identify children with autism spectrum disorder (ASD) at 18 months was tested on 37 children clinically referred for ASD and 46 children at elevated likelihood of developing ASD due to having an affected brother/sister. At 30 months the clinically referred children all received a…

Chan, Neilson; Sanner, Catherine M.; McGregor, Hadley A.; Preston, Amanda E.; Neece, Cameron L. – Journal of Mental Health Research in Intellectual Disabilities, 2021
Introduction: Children with developmental delays (DD) and Autism Spectrum Disorder (ASD) are at a high risk for emotional and behavioral concerns. Research examining co-occurring anxiety in those with ASD during early childhood is scarce. The current study examined rates, symptom manifestation, and parenting risk correlates of anxiety among young…
