Perspectives on the measurement of self-perceived cognitive function in older adults

INTRODUCTION: This survey investigated perspectives of research and clinical professionals on optimal content and features of measurement of self-perceived cognitive functioning.

METHODS: Respondents were professionals working with older adults with self-reported cognitive concerns. The survey addressed views on harmonization and preferences for items, response formatting, practical features, and instrument validation. We evaluated item preferences in consideration of a previous statistical harmonization.

RESULTS: Ninety professionals from 20 different countries completed the survey. Most professionals (87%) indicated a need for a harmonized instrument. Respondents agreed that an instrument should measure current ability alongside change therein, focus on memory, and adopt Likert scale responses. Recommendations for assessment timeframe, practical features, and validation priorities varied. Respondents differentially endorsed items previously found to be statistically informative.

DISCUSSION: Respondents agreed on overarching measurement topics, with varying recommendations for specific content and features. Together with statistical information, these results provide a starting point for a harmonized instrument. Highlights: Professionals see a need for a harmonized tool to measure cognitive concerns. Professionals have diverse preferences for measurement content and its validation. Item relevance as seen by professionals aligned considerably with statistical value. Integration of statistical information with expert and patient opinion is crucial.
