Comparing paired-stimulus and multiple-stimulus concurrent-chains preference assessments: Consistency,...

Area of Science:

• Behavioral Psychology
• Applied Behavior Analysis
• Preference Assessment Methods

Background:

• Concurrent-chains preference assessments are utilized to determine individual preferences for various activities and interventions.
• The standard method involves simultaneous presentation of stimuli in a multiple-stimulus array, with repeated selections informing preference hierarchies.

Purpose of the Study:

• To compare the efficiency and efficacy of a novel paired-array stimulus presentation method against the traditional multiple-stimulus model for concurrent-chains preference assessments.
• To evaluate the correspondence between preference rankings derived from both assessment formats.

Main Methods:

• Participants completed concurrent-chains preference assessments using both a traditional multiple-stimulus array format and a newly developed paired-array format.
• Stimuli (e.g., pictures, colored cards) represented various activities or interventions.
• Preference hierarchies were established based on accumulated selection frequency across trials for each method.

Main Results:

• Preference assessments conducted using the paired-array format were completed significantly faster than those using the multiple-stimulus format.
• A high degree of correspondence was observed between the preference rankings generated by the paired-array and multiple-stimulus methods.
• Both methods successfully identified highly preferred activities and established preference hierarchies.

Conclusions:

• The paired-array format offers a more time-efficient alternative for conducting concurrent-chains preference assessments without compromising the accuracy of preference rankings.
• This finding has implications for optimizing preference assessment procedures in clinical and educational settings, particularly when time is a constraint.
• The paired-array method maintains the integrity of preference assessment while enhancing practical application.
