Preference testing: a comparison of two presentation methods.

Paired and group presentation methods of preference testing were compared with eight learners with severe-profound developmental disabilities. Each presentation method was also compared with staff rankings of learners' preferences. Similar preferences were identified with both presentation methods. Although the paired presentation took more time to administer, it elicited more consistent preference information than the group presentation. Staff preference rankings were not highly correlated with either the group or paired presentation. However, items identified as most preferred by staff and by both presentation methods were similar.
