Assessing the utility of a demand assessment for functional analysis

Area of Science:

• Behavioral Psychology
• Developmental Psychology
• Clinical Psychology

Background:

• Functional analysis is crucial for understanding behavior disorders in autism spectrum disorder (ASD).
• Identifying specific task demands that elicit problem behavior is key for effective intervention design.
• Previous methods may not consistently differentiate between high and low-probability demands.

Purpose of the Study:

• To evaluate an assessment's effectiveness in identifying functional analysis demand conditions for individuals with autism.
• To determine if low-probability demands yield clearer functional analysis outcomes compared to high-probability demands.

Main Methods:

• A demand assessment was conducted with 4 individuals diagnosed with autism.
• Therapists presented various tasks, and observers recorded problem behavior and compliance.
• Demands were categorized as low-probability (low compliance/high problem behavior) or high-probability (high compliance/low problem behavior).

Main Results:

• The assessment successfully identified low- and high-probability demands for participants.
• Clearer functional analysis outcomes were achieved for 3 out of 4 participants when using low-probability demands.
• This suggests low-probability demands are more informative for functional analysis in this population.

Conclusions:

• The evaluated assessment is a useful tool for identifying relevant task demands in functional analyses for individuals with autism.
• Utilizing low-probability demands in functional analysis can lead to more definitive results.
• This approach aids in developing more targeted and effective behavioral interventions for autism.
