Further refinement of video-based brief multiple-stimulus without replacement preference assessments

Area of Science:

• Behavior analysis
• Autism spectrum disorder research
• Preference assessment methodology

Background:

• Understanding the preferences of children with autism is crucial for engagement and learning.
• Preference assessments help identify motivating activities.
• Video-based assessments offer a novel approach to preference identification.

Purpose of the Study:

• To compare the effectiveness of two video-based preference assessment methods for children with autism.
• To evaluate the concordance between different preference assessment formats and instructor rankings.
• To determine the reliability of a brief video-based multiple-stimulus without replacement preference assessment.

Main Methods:

• Four children with autism participated in the study.
• A video-based multiple-stimulus without replacement preference assessment was administered with and without access to chosen activities (MSWO-NO vs. MSWO-WA).
• Instructor rankings of activity preferences were collected and compared to assessment results.

Main Results:

• Strong to moderate correlations were observed between MSWO-NO and MSWO-WA results across all participants.
• The correlation between MSWO-WA and instructor rankings varied from strong to low.
• The findings indicate consistency in preference identification between the two assessment conditions.

Conclusions:

• Video-based preference assessments, even without immediate access to activities, appear to be a reliable method for assessing preferences in children with autism.
• Further research is needed to explore the nuances of instructor rankings versus direct assessment outcomes.
• These findings support the utility of brief, video-based preference assessments in applied settings.
