Test-Retest Reliability and Internal Consistency
| Test-Retest Reliability (Person r) | Internal Consistency (Cronbach’s Alpha) | |||
|---|---|---|---|---|
| Task | Patients (n = 208) | Controls (n = 148) | Patients (n = 218) | Controls (n = 154) |
| BLERT | .809 | .622 | .778 | .570 |
| ER-40 | .710 | .679 | .754 | .555 |
| Eyes | .806 | .716 | .750 | .640 |
| IBT | .587 | .511 | .538 | .503 |
| Hinting | .695 | .509 | .681 | .635 |
| MiniPONS | .721 | .663 | .712 | .656 |
| SAT-MC | .573 | .554 | .786 | .735 |
| TASIT | .636 | .534 | .807 | .825 |
| BLERT CR | .613 | .701 | .962 | .932 |
| BLERT RT | .658 | .660 | .939 | .951 |
| ER-40 CR | .625 | .796 | .973 | .962 |
| ER-40 RT | .662 | .629 | .915 | .914 |
| TASIT RT | .687 | .559 | .920 | .881 |
Note: Due to the time limit on responding, many participants had missed trials on the IBT. Estimates of internal consistency for this task are therefore based on much smaller samples of participants (26 patients and 38 controls) who responded to all items.
