To the Editor: In their randomized controlled trial, Dr Stanley and colleagues1 showed that older patients with generalized anxiety disorder who received cognitive behavior therapy (CBT) had greater improvements in worry severity, depressive symptoms, and general mental health than those who received enhanced usual care (EUC). Because of several important factors that were not included in the analyses, we have some concerns about the interpretation of these findings.
