Project Activities
Approximately 320 children diagnosed with autism spectrum disorders in 160 kindergarten to 2nd grade classrooms in 40 schools will participate in the study. Schools will be randomly assigned to either the intervention condition or the typical classroom service model. Schools in Florida and California will participate. The intervention will be implemented for one academic year. Students' active engagement, social, communication, behavioral, and academic outcomes will be evaluated for the children in the intervention and the typical classroom service model. Researchers will also examine how child characteristics and fidelity of implementation influence treatment outcomes.
Structured Abstract
Setting
Participating students will be from Florida and California.
Sample
Approximately 320 children diagnosed with autism spectrum disorders in 160 kindergarten to 2nd grade classrooms in 40 schools will participate in the study.
The SCERTS Curriculum incorporates behavioral and developmental approaches to address the social communication and emotional regulation deficits in children with autism spectrum disorder. The intervention focuses on building children's capacity to engage in reciprocal social interactions and the use of language in a range of natural settings. Challenges in social communication are addressed in a developmental continuum which encompasses the ability to communicate with intent, the acquisition and use of conventional gestures, use of words and word combinations, acquisition of grammar, and conversational discourse. Self regulation difficulties are addressed by enhancing children's capacity to use sensory motor and cognitive or linguistic strategies to support attention and engagement. The third component of the intervention is the use of transactional supports, such as a communicative partner adjusting their language use or the use of visual supports, to optimize social interactions and maximize learning and participation in a variety of settings.
Research design and methods
The research team will utilize a cluster randomized design with repeated measures to evaluate the developmental outcomes of children being served in classrooms that utilize one of the two types of treatment models. Schools will be randomly assigned to either the SCERTS or typical classroom service model.
Control condition
The control condition will be the typical classroom service model.
Key measures
The curriculum will be evaluated using commercial and non-commercial measures. Outcome measures include the Vineland Behavior Adaptive Scales –II, Social Responsiveness Scale, Repetitive Behavior Scale-Revise, Children's Communication Checklist-2, Child Behavior Checklist. Peabody Picture Vocabulary Test; Expressive One Word Picture Vocabulary, The Dynamic Indicators of Basic Early Literacy Skills; Test of Word Reading Efficiency and the Stanford Achievement Test - 10. Observational measures of children's active engagement and fidelity measures will also be administered.
Data analytic strategy
Growth curve modeling will be used to analyze differences between the growth rates of treatment and control students' adaptive behavior, active engagement, social characteristics and academic outcomes. In addition, the researchers will investigate potential mediators (e.g., fidelity) and moderators (e.g., age of treatment entry) of intervention effects.
