CBT significantly improved general mental health quality of life compared with enhanced usual care in older adults with GAD in primary care (MCS 49.6 vs 45.3, p=.008), with gains maintained over 12-month follow-up.
| Effect size | MCS 49.6 vs 45.3 |
| CI | 95% CI 47.4 to 51.8 (CBT) vs 95% CI 42.6 to 47.9 (EUC) |
| Follow-up | 12 months |
| Comparator | Enhanced usual care (biweekly supportive phone calls for 3 months plus routine primary care) |
| Effect summary | improvement; MCS 49.6 vs 45.3; CI: 95% CI 47.4 to 51.8 (CBT) vs 95% CI 42.6 to 47.9 (EUC) |
| Effect modifiers | [{"modifier": "treatment expectancy", "interaction_p": "", "direction": "attenuates", "stratum_details": "When treatment expectancy added as covariate, MCS group difference only approached significance (p=.04)", "plain_language": "Part of the mental health quality-of-life improvement from CBT may reflect higher expectations rather than the therapy itself. Accounting for expectations made the benefit borderline.", "annotation_notes": "MCS p=.008 without expectancy, p=.04 with expectancy covariate (still borderline significant at alpha=.025)"}] |
