Assessing preference in elders with dementia using multimedia and verbal pleasant events schedules

The current study compared an abbreviated oral interview version of the Pleasant Events Schedule – Alzheimer's Disease (PES‐AD) to a multimedia‐supplemented version. Both measures identified multiple preferred items and their scores were moderately correlated (r = .481). Direct observations were conducted to determine whether either of the two measures predicted subsequent engagement. For all nine individuals with dementia, items endorsed as preferred by both versions of the PES‐AD resulted in high levels of engagement and items endorsed as non‐preferred items on both measures resulted in low to moderate levels of engagement. Individuals with MMSE scores of 10 or higher had more stable and differentiated patterns of engagement than individuals with scores below 10. For individuals with higher MMSE scores, items endorsed only by the multimedia version resulted in high engagement levels (i.e., true positive) while items endorsed only on the verbal presentation resulted in low levels (i.e., false positive).
