Distribution of CASI subdomain scores and CASI sum score in two tinnitus groups
| CASI subdomains and sum score | Mild tinnitus group Mean ± SD | Severe tinnitus group Mean ± SD | t value | p value |
|---|---|---|---|---|
| LTM | 8.72 ± 1.30 | 8.45 ± 1.38 | 1.436 | .153 |
| STM | 8.15 ± 1.99 | 5.67 ± 1.74 | 9.548 | <.001 |
| Att | 7.74 ± 0. 69 | 7.46 ± 0.76 | 2.689 | <.008 |
| Conc | 9.42 ± 0.92 | 8.38 ± 1.62 | 5.537 | <.001 |
| Ori | 8.03 ± 0.89 | 6.51 ± 1.41 | 9.102 | <.001 |
| AJ | 10.13 ± 1.45 | 8.21 ± 1.70 | 8.629 | <.001 |
| Lang | 9.65 ± 0.71 | 8.96 ± 1.10 | 5.318 | <.001 |
| VC | 8.99 ± 1.12 | 7.96 ± 1.57 | 5.377 | <.001 |
| Flu | 7.68 ± 1.58 | 7.13 ± 1.88 | 2.297 | .023 |
| Sum | 87.04 ± 7.08 | 73.98 ± 8.64 | 11.759 | <.001 |
No significant difference in demographic or clinical characteristics was detected between mild tinnitus group and severe tinnitus group; t tests were used for statistical analysis. CASI, Cognitive Abilities Screening Instrument; SD, standard deviation; LTM, long‐term memory; STM, short‐term memory; Att, attention; Conc, concentration or mental manipulation; Ori, orientation; AJ, abstraction and judgment; Lang, language abilities; VC, visual construction; Flu, category fluency.
