Insights

The Joint Attention, Symbolic Play, Engagement, and Regulation (JASPER) intervention improved developmental outcomes for young children with autism in community settings. These gains in joint engagement, attention, and play skills were maintained after treatment.

Area of Science:

  • Developmental Psychology
  • Clinical Psychology
  • Special Education

Background:

  • Research-effective interventions often show reduced efficacy in community settings.
  • Few studies use randomized controlled designs to test lab-based autism interventions in community settings.
  • This study addresses the gap by evaluating a specific intervention in a community context.

Purpose of the Study:

  • To examine the efficacy of the Joint Attention, Symbolic Play, Engagement, and Regulation (JASPER) intervention for children with autism in community-based early intervention classrooms.
  • To compare outcomes for children receiving JASPER intervention versus treatment as usual.
  • To assess the maintenance of intervention effects at follow-up.

Main Methods:

  • A randomized controlled trial involving 113 children with autism in low-resource neighborhoods.
  • Participants were assigned to either the JASPER intervention or a treatment-as-usual waitlist for 10 weeks.
  • Outcomes were assessed immediately after the intervention and at a 1-month follow-up.

Main Results:

  • Teaching assistants successfully delivered the JASPER intervention with adequate fidelity.
  • Children in the JASPER group showed significant improvements in joint engagement, joint attention, and play skills compared to the control group.
  • These developmental gains were sustained at the 1-month follow-up assessment.

Conclusions:

  • Supervised teaching assistants can effectively deliver the JASPER intervention to toddlers with autism in community settings.
  • The JASPER intervention leads to significant improvements in core developmental outcomes for young children with autism.
  • Findings support the use of JASPER as a viable community-based intervention for autism.

Modeling in Therapy01:26

Modeling in Therapy

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Autism Spectrum Disorder01:19

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Community Based Intervention

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Operant Conditioning Intervention01:24

Operant Conditioning Intervention

Operant conditioning serves as a foundational principle in therapeutic interventions aimed at modifying maladaptive behaviors. Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.
In operant conditioning, behaviors that are...

Learning Disabilities01:25

Learning Disabilities

Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

Behavior Therapy

Behavior therapy incorporates diverse techniques rooted in classical conditioning principles to address maladaptive behaviors and anxiety disorders. These methods aim to reduce avoidance behaviors, foster adaptive coping mechanisms, and alter associations between stimuli and responses, making them effective in a wide range of therapeutic contexts.
Exposure therapy is a cornerstone of behavioral treatment for anxiety disorders. It involves systematic exposure to feared stimuli, either in real...
