(Press-News.org) A 24 week parent training program, which provided specific techniques to manage disruptive behaviors of children with autism spectrum disorder, resulted in a greater reduction in disruptive and noncompliant behavior compared to parent education, according to a study in the April 21 issue of JAMA, a theme issue on child health.
Autism spectrum disorder (ASD) affects an estimated 6 per 1,000 children worldwide and is a major public health challenge. As many as 50 percent of children with ASD exhibit behavioral problems, including tantrums, noncompliance, aggression, and self-injury. Behavioral interventions are used to treat disruptive behavior but have not been evaluated in large-scale randomized trials, according to background information in the article.
Lawrence Scahill, M.S.N., Ph.D., of Children's Healthcare of Atlanta and Emory University, Atlanta, and colleagues conducted a study in which children (age 3-7 years) with ASD were randomly assigned to parent training (n = 89) or parent education (n = 91) at 6 centers (Emory University, Indiana University, Ohio State University, University of Pittsburgh, University of Rochester, Yale University).
Parent training provided specific strategies to manage disruptive behavior and was delivered individually to the parents in 11 core sessions of 60 to 90 minutes' duration, up to 2 optional sessions, 1 home visit, and up to 6 parent-child coaching sessions over 16 weeks. Parent training also included 1 home visit and 2 telephone booster sessions between weeks 16 and 24. Parent education provided information about autism but no behavior management strategies and included 12 sessions of 60 to 90 minutes and 1 home visit over 24 weeks.
On parent-rated measures of disruptive and noncompliant behavior, parent training, compared to parent education, showed a greater reduction on two scales: a 48 percent vs 32 percent decline on the Aberrant Behavior Checklist-Irritability subscale; and a 55 percent vs 34 percent decline on the Home Situations Questionnaire-Autism Spectrum Disorder. Both treatment groups improved over time, although neither measure met the prespecified minimal clinically important difference. The authors suggest that one possible explanation for the smaller than anticipated differences between groups is the larger than predicted improvement in the parent education group.
Parent training was superior to parent education on a measure of overall improvement as judged by a clinician who was blinded to research assignment (69 percent vs 40 percent).
The authors write that the cost-effectiveness of the 2 interventions needs to be investigated, and that future analyses may identify child and family characteristics that predict success with parent training or parent education.
"To our knowledge, this is the largest randomized trial of any behavioral intervention for children with ASD. The results of this multisite study provide empirical support for wider implementation of this structured, relatively brief parent training intervention for young children with ASD."

Editorial: Promising Forecast for Autism Spectrum Disorders
"Although specific behavioral training was superior, both groups reported considerable improvement over baseline, suggesting that even regular intensive education about autism provided value to parents and translated to perceived behavioral improvements in their children," writes Bryan H. King, M.D., M.B.A., of the University of Washington and Seattle Children's Hospital, Seattle, in an accompanying editorial.
"Some challenges for the future include what can be learned about the children who did not respond to behavioral intervention and why some children of parents who were not educated about behavioral principles also improved. Autism is a diverse condition, and a better understanding of how psychosocial interventions work will be critical for determining how to personalize treatment."

In a pilot study that included children at high risk for type 1 diabetes, daily high-dose oral insulin, compared with placebo, resulted in an immune response to insulin without hypoglycemia, findings that support the need for a phase 3 trial to determine whether oral insulin can prevent islet autoimmunity and diabetes in high-risk children, according to a study in the April 21 issue of JAMA, a theme issue on child health.
A few specific proteins are often the trigger for immune responses that cause autoimmune diseases. This has led to the experimental use of antigenspecific ...
The incidence of a potentially life-threatening complication of diabetes, diabetic ketoacidosis, in youth in Colorado at the time of diagnosis of type 1 diabetes increased by 55 percent between 1998 and 2012, suggesting a growing number of youth may experience delays in diagnosis and treatment, according to a study in the April 21 issue of JAMA, a theme issue on child health.
Diabetic ketoacidosis (DKA) at the time of type 1 diabetes (T1D) diagnosis has detrimental long-term effects and is characterized by dangerously high blood sugar and the presence of substances in ...
A multi-site study sponsored by the National Institute of Mental Health (NIMH) finds young children with autism spectrum disorder and serious behavioral problems respond positively to a 24-week structured parent training. The benefits of parent training endured for up to six months post intervention.
Published in the April 21 issue of the Journal of the American Medical Association the study found parent training was more effective in reducing disruptive and aggressive behavior than 24 weeks of parent education. Parent training provided parents with specific strategies ...
Researchers from the University of Tokyo have revamped an old e-paper concept to make an inexpensive handwriting-enabled e-paper well suited to large displays like whiteboards. They describe the e-paper in the Journal of Applied Physics, from AIP Publishing.
Traditional ink and paper is convenient for both reading and writing. In e-paper development the writing feature has generally lagged behind. Handwriting-enabled displays mainly show up in the inexpensive, but feature-limited realm of children's toys, and in the high-end realm of touch-screen e-readers and smart ...

AURORA, Colo. (April 21, 2015) - Children at risk for type 1 diabetes, who were given daily doses of oral insulin, developed a protective immune response to the disease that researchers with the Barbara Davis Center for Childhood Diabetes at the University of Colorado Anschutz Medical Campus say could possibly lay the groundwork for a vaccine against the chronic illness.
The pilot study, published Tuesday, April 21, in the Journal of the American Medical Association (JAMA), was carried out in the U.S., Germany, Austria and the United Kingdom.

Sweet potatoes from all over the world naturally contain genes from the bacterium Agrobacterium. Researchers from UGent and the International Potato Institute publish this discovery in PNAS. Sweet potato is one of the most important food crops for human consumption in the world. Because of the presence of this 'foreign' DNA, sweet potato can be seen as a 'natural GMO.'
The researchers discovered the foreign DNA sequences of Agrobacterium while searching the genome - this is the entire DNA-code - of sweet potato for viral diseases. Instead of contributing this peculiar ...
