CBT significantly improved worry severity compared with enhanced usual care at 3 months post-treatment, with mean PSWQ scores of 45.6 (CBT) vs 54.4 (EUC), p<.0001, and the improvement was maintained over 12-month follow-up.
| Effect size | PSWQ 45.6 vs 54.4 |
| CI | 95% CI 41.3 to 47.8 (CBT) vs 95% CI 51.4 to 57.3 (EUC) |
| Follow-up | 12 months |
| Comparator | Enhanced usual care (biweekly supportive phone calls for 3 months plus routine primary care) |
| Effect summary | improvement; PSWQ 45.6 vs 54.4; CI: 95% CI 41.3 to 47.8 (CBT) vs 95% CI 51.4 to 57.3 (EUC) |
