Cognitive Behavior Therapy for Generalized Anxiety Disorder Among Older Adults in Primary Care: A Randomized Clinical Trial

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 o

Effect: 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)

CBT did not produce significantly greater improvement than enhanced usual care on clinician-rated GAD severity (GADSS), despite a numerically larger mean change in CBT (2.8 points) than EUC (1.4 point

Effect: null; mean change 2.8 (CBT) vs 1.4 (EUC)

CBT significantly improved coexistent depressive symptoms compared with enhanced usual care in older adults with GAD in primary care (BDI 10.2 vs 12.8, p=.02), with gains maintained over 12-month foll

Effect: improvement; BDI 10.2 vs 12.8; CI: 95% CI 8.5 to 11.9 (CBT) vs 95% CI 10.5 to 15.1 (EUC)

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-mo

Effect: 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)

CBT did not produce significantly greater improvement than enhanced usual care on clinician-rated anxiety severity (SIGH-A) in older adults with GAD in primary care.

Effect: null
