Longitudinal analysis of leisure-item preferences.
Journal of Applied Behavior Analysis,
34, 179-184.
Twenty-two individuals with developmental disabilities
participated in two leisure-item preference assessments, spaced
approximately 16 months apart. Results showed (a) an overall
increase in item contact across assessments for 13 participants
and (b) at least some overlap across assessments in the five most
highly ranked items for every participant. These results
highlight individual differences in the stability of preference
over time and suggest the need for research to identify the
determinants of temporal shifts in preference.
