Three steps of PLS methodology
| Cognitive domain | ||||
|---|---|---|---|---|
| Perceptual speed/working memory | Orientation | Episodic memory | Visual spatial | |
| Step 1: Original PLS Combination (Combination 1) |
1) Symbol Digit Modalities (Perceptual Speed) 2) Digit Ordering (Working Memory) |
1) MMSE Orientation to Time |
1) Logical Memory Delayed 2) Word List Memory Delayed |
1) Judgment of Line Orientation 2) Raven’s Progressive Matrices (subset of 9 items from A and B) |
| Step 2: Added MMSE Orientation to Place (Combination 2) |
1) Symbol Digit Modalities (Perceptual Speed) 2) Digit Ordering (Working Memory) |
1) MMSE Orientation to Time 2) MMSE Orientation to Place |
1) Logical Memory Delayed 2) Word List Memory Delayed |
1) Judgment of Line Orientation 2) Raven’s Progressive Matrices (subset of 9 items from A and B) |
| Step 3: Removed Digit Ordering (Combination 3) | 1) Symbol Digit Modalities (Perceptual Speed) |
1) MMSE Orientation to Time 2) MMSE Orientation to Place |
1) Logical Memory Delayed 2) Word List Memory Delayed |
1) Judgment of Line Orientation 2) Raven’s Progressive Matrices (subset of 9 items from A and B) |
