Preschoolers with autism gain when teachers foster shared attention

Study of JASPER method among first to demonstrate benefits of using a behavioral intervention in a group preschool setting
March 03, 2016

In a new study, researchers showed that preschoolers with autism gain more language and initiate more communication when teachers learn to use a simplified version of a behavioral therapy that emphasizes shared attention and child-directed play.

The study is among the first to show that an early intervention for autism – proven effective for one-on-one behavioral therapy with an autism specialist – can be successfully adapted for classroom use.

“These results are exciting since few studies have demonstrated such benefits when moving an intervention into the community,” says the study’s senior author, psychologist Connie Kasari, of the University of California, Los Angeles. “The success can be attributed partly to the commitment and enthusiasm of our community partners.”

 Results of the study, funded by Autism Speaks, appear in the Journal of Autism and Developmental Disabilities.

Kasari developed the autism intervention – dubbed JASPER for “Joint Attention, Symbolic Play, Engagement and Regulation – over the last 15 years. JASPER emphasizes joint attention, or shared focus, by engaging children in play routines rich in both verbal and nonverbal communication. It differs from many autism interventions in that the facilitator follows the child’s lead rather than directing his or her attention. The facilitator also encourages the child to initiate interactions rather than simply respond to questions and other prompts.  

Earlier studies showed that JASPER significantly improves sociability and communication in children with autism when delivered one-on-one by highly trained behavioral therapists.

“This study moves JASPER from a one-on-one therapy model to classroom settings using small groups of children and focusing on engagement between children, adults and peers,” Kasari explains. “This highlights the promise of interventions such as JASPER that can easily be modified to fit the existing classroom structure.”

Most preschoolers with autism receive the majority of their intervention services in just such a group setting. In a typical special education preschool, a teacher and aide must divide their attention among at least 8 to 12 students.

In preparation for their study, Kasari and her team worked with special education preschool teachers to simplify and adapt the JASPER method for use in classrooms.

Diverse classrooms
They then enrolled twelve half-day preschool classes, each with eight children, a special education teacher and a teaching assistant in their study. The classes were part of a diverse Los Angeles school district. Just over 20 percent of the participating children were Hispanic, 16 percent were Asian, and 13 percent were African American.  

In order to determine the intervention’s effectiveness, the researchers created a “control group” by putting six of the twelve classes on a wait list while the other six classes completed the eight-week intervention.

The researchers then provided each teacher and teaching assistant in the “intervention group” with two, half-hour introductions to the JASPER method. The teachers and assistants used the JASPER techniques during a daily 15-minute play time with their students. For the first four weeks, the researchers joined the play time to provide coaching. During the second four weeks, they reduced the coaching sessions to three or four times a week.

When less is more
During the coaching, many of the teachers needed reminders to do less directing and initiating – but instead follow each child’s lead during play and other interactions, the researchers report.

At the end of the eight weeks, the researchers used standardized checklists to evaluate how often children initiated social interactions and engaged in shared imaginative play. They also assessed language – in particular the length of each child’s verbal communications (one word, two words, three words, etc.)

Gains in communication and social play
Compared with the wait-listed students, the preschoolers who received the intervention showed more shared attention with others and also initiated communication more often – using gestures, language or both. These children also used longer strings of words, on average, when communicating with their teachers.

The researchers emphasize that these improvements persisted when they returned to the classrooms three months after the eight-week intervention to reassess the students’ social communication skills.  

“While individual treatment is extremely valuable, children with autism need to be supported in applying the skills they learn in everyday settings such as at school,” comments Lucia Murillo, Autism Speaks’ assistant director of education research. “It’s important that evidence-based treatments be made practical for classroom use so teachers can more easily integrate them into a child’s school day,” she adds. “More studies like this will help ensure that teachers have a greater collection of tools to draw from when it comes to teaching children with autism or other developmental challenges.”
