Abstract

Objective: The Uniform Data Set 3.0 neuropsychological battery (UDS3NB) is well developed for research with Alzheimer’s disease and related dementias, and may serve as a common set of measures of cognitive decline across neurodegenerative diseases. However, the battery has not been formally assessed in persons with Parkinson’s disease (PD). The current research provides initial information on the convergent and ecological validity of the UDS3NB in individuals with PD. Methods: Participants included 75 individuals diagnosed with PD from the Arizona Study of Aging and Neurodegenerative Disorders. Clinical dementia ratings, administered independently from the cognitive measures, identified individuals as having normal cognition (n = 38), Mild Cognitive Impairment (MCI; n = 25) and dementia (n = 12). UDS3NB measures were compared between these groups, and correlations between UDS3NB measures, gold standard neuropsychological measures, and informant rated activities of daily living ability (ADL) were evaluated. Results: At the group-level, UDS3NB scores followed the expected pattern with higher scores in participants with PD but no cognitive diagnosis and lower in those with dementia; scores in the MCI group were between these extremes. Convergent validity was suggested by moderate correlations between UDS specific measures (i.e., Craft story) and measures such as the RAVLT. Ecological validity was suggested by statistically significant correlations between UDS3NB performance and caregiver ratings of ADLs, with speed and executive functioning measures (Trailmaking A; r = −.51, p < .01; Trailmaking B; r = −.51, p < .01) most strongly related to reported daily functioning. Conclusions: Findings provide initial support for the convergent and ecological validity of the UDS3NB in individuals with PD. Implications and future directions for this battery are discussed.
