Table 5.
Mean values and standard deviations of patients’ scores on executive and working memory tests.
| Dependent variable | Patients with OCD | |
|---|---|---|
| M ± SD | Range | |
| Verbal fluency score | 20.2 ± 5.4 | 9 to 36 |
| Stroop test scores | ||
| Word-reading (card A) | 101.5 ± 17.0 | 70 to 136 |
| Color-naming (card B) | 78.7 ± 14.6 | 45 to 109 |
| Color-word condition (card C) | 44.0 ± 13.6 | 15 to 78 |
| Color-word minus color-naming | −34.7 ± 9.9 | −59 to −15 |
| Golden’s inhibition score | −0.2 ± 9.9 | −22.2 to 22.8 |
| d2 test score | 356 ± 107 | 160 to 603 |
| d2 error rate (%) | 6.0 ± 7.0 | 0.0 to 37.0 |
| Hayling RT (ms), completion condition | 1,050 ± 496 | 519 to 3,720 |
| Hayling RT (ms), inhibition condition | 3,019 ± 1,690 | 1,002 to 8,752 |
| Number of errors in the inhibition condition | 9.8 ± 2.3 | 4 to 13 |
| Task-switching RT (ms), all trials | 1,246 ± 622 | 534 to 3,479 |
| Task-switching, switching cost (ms) | 196 ± 229 | −111 to 1,215 |
| Task-switching, incongruency cost (ms) | 308 ± 398 | −125 to 2,268 |
| Task-switching, error rate (%) | 4.2 ± 4.6 | 0.0 to 22.2 |
| Reading span scores | 52.5 ± 14.6 | 25 to 86 |
| Backward location span scores | 111.3 ± 23.4 | 57 to 157 |
Sixty-three patients performed the reading span and backward location span tests, whereas 53 of them performed the other tests. Hayling = Hayling sentence completion test, Task-switching = task-switching test, RT = response time.
