Addressing Prompt Dependency in the Treatment of Challenging Behavior Maintained by Access to Tangible Items

Area of Science:

• Developmental Disabilities
• Autism Spectrum Disorder
• Behavioral Interventions

Background:

• Prompt dependency is a significant challenge for individuals with developmental disabilities, especially autism spectrum disorder (ASD).
• Prior research indicates that various interventions can mitigate prompt dependency.
• Functional communication training (FCT) is a common approach for addressing challenging behaviors.

Purpose of the Study:

• To evaluate the effectiveness of different treatments in reducing prompt dependency during FCT.
• To address challenging behaviors maintained by access to tangible items in an adolescent female with ASD.
• To compare the efficacy of differential reinforcement, vocal prompt fading, extended response intervals, and full physical prompts with prompt delay.

Main Methods:

• The study involved a 16-year-old female diagnosed with autism spectrum disorder.
• Interventions compared included differential reinforcement, vocal prompt fading, extended response intervals, and full physical prompts with constant prompt delay.
• The primary outcome measure was the increase in independent functional communication responses.

Main Results:

• The evaluated treatments for prompt dependency were effective in increasing independent functional communication responses.
• Challenging behaviors were reduced to zero rates following the implementation of the interventions.
• The combination of interventions successfully decreased reliance on prompts.

Conclusions:

• The study demonstrates a successful strategy for reducing prompt dependency in individuals with ASD.
• Functional communication training combined with specific prompt reduction techniques can effectively manage challenging behaviors.
• This research offers valuable insights for therapeutic interventions targeting communication and behavior in ASD.
