Objective: Repetition of stimuli across neuropsychological instruments may have an impact on assessment such as an unintentional priming effect, with potential clinical implications. For example, for a patient on the cusp of Mild and Major Cognitive Impairment, redundant stimuli could influence responses, scoring, and eventual diagnosis. Likewise, awareness of stimuli overlap may enrich qualitative interpretations of neuropsychological assessment data (e.g., providing evidence to help distinguish between dysexecutive and amnestic memory deficits). The present study examines the frequency of stimuli redundancy to illustrate potential issues. Method: We examined stimuli redundancy across two sets of frequently used instruments for memory assessment: (a) the top 10 most commonly used instruments (Rabin et al., 2005), and (b) our clinic's standard battery. The frequency of each item was measured and proportions of shared stimuli were calculated. Our analyses also examined synonyms, categorical overlap, and presentation modality. A case example is provided for illustrative purposes. Results: The results confirm the presence of stimuli redundancy across tests. The range for overlap between individual instruments was 0%-7.7%. For example, Dementia Rating Scale-2 and Hopkins Verbal Learning Test had 3.3% overlap (3 overlapping items/91 total items). Our case study specifically illustrates the utility of accounting for stimuli repetition for identifying dysexecutive performance on memory tests. Conclusion: The rate of stimuli redundancy was relatively low but present. Importantly, many of the overlapping stimuli are used for memory assessment; awareness of this issue could provide useful interpretive information to identify dysexecutive (versus amnestic) performance on memory tests.
