ysis: The raw and IRT-derived HBC scores were analyzed with and without the MCI Screen using logistic regression to predict FAST stage. Results: The HBC and MCI Screen measures correlated weakly. Combining their information optimized classification of functionally normal (FAST 1, 2) vs. functionally impaired subjects (FAST 3, 4). The item difficulty and discrimination measures showed that 15 of the 16 HBC items had good psychometric validity. The raw HBC scores and IRT-derived, theta scores gave similar classification accuracies. Conclusions: The weak correlation between subjective and objective cognitive measures, and the improved classification when they are combined, indicates the subjective and objective information measure different aspects of cognitive performance. 15 of 16 HBC items have good psychometric validity. It would be helpful to understand the different aspects of cognition captured by subjective and objective assessment so that they can be more gainfully exploited.
