Using trial-based functional analysis to design effective interventions for students diagnosed with autism spectrum...

Area of Science:

• Applied Behavior Analysis
• Developmental Psychology
• Special Education

Background:

• Functional behavior assessments and function-based interventions are key for managing challenging behaviors in children.
• Traditional functional analysis methods present limitations in real-world educational settings, including time, expertise, and artificiality.
• Trial-based functional analysis (TBFA) is a modified approach designed to overcome these practical challenges.

Purpose of the Study:

• To assess the function of challenging behaviors in early childhood education students with autism spectrum disorder (ASD) using TBFA.
• To evaluate the effectiveness of individualized function-based interventions derived from TBFA.
• To determine the feasibility of TBFA in applied educational settings.

Main Methods:

• Conducted trial-based functional analyses with three early childhood students diagnosed with ASD.
• Implemented individualized function-based interventions tailored to the identified behavioral functions.
• Observed and recorded changes in challenging behaviors and classroom engagement.

Main Results:

• All participants demonstrated significant decreases in challenging behaviors following the function-based interventions.
• Classroom engagement increased notably for students who received the individualized interventions.
• TBFA proved to be a feasible method for informing intervention strategies in an educational context.

Conclusions:

• Trial-based functional analysis is a viable and effective tool for understanding the function of challenging behaviors in educational settings for children with ASD.
• Function-based interventions derived from TBFA can lead to positive behavioral outcomes and improved classroom participation.
• The findings support the practical application of TBFA in informing intervention design within applied educational environments.
