| Abstract: | Three methods of assessing preference for stimuli were compared in four adults with a diagnosis of schizophrenia. During phase 1, a survey method, a verbal stimulus choice method, and a pictorial stimulus choice method of assessing preference for four categories of stimuli were administered. During phase 2, a coupon system was used to determine which categories of stimuli actually functioned as reinforcers for each participant. Comparisons between the three preference assessment methods were then conducted based on the results of the reinforcer assessment. Results showed that, overall, there were few differences in total accuracy among the preference assessment procedures. Copyright © 2003 John Wiley & Sons, Ltd. |
