Abstract

The objective of this analysis was to develop a measure of neuropsychological performance for cardiac surgery and assess its psychometric properties. Older patients (n=210) underwent a neuropsychological battery using nine assessments. The number of factors was identified with variable reduction methods. Item response theory-based factor analysis methods were used to evaluate the measure. Modified parallel analysis supported a single factor, and the battery formed an internally consistent set (coefficient alpha=0.82). The developed measure provided a reliable, continuous measure (reliability >0.90) across a broad range of performance (−1.5 SD units to +1.0 SD units) with minimal ceiling and floor effects.
