Does Cognitive Behavioral Therapy actually make a difference, or is it overhyped?

Beyond its well-established efficacy for anxiety and depression, CBT has strong, replicated randomized-trial evidence for chronic insomnia — a flagship meta-analysis in Annals of Internal Medicine, later refined by a component network meta-analysis identifying which parts of the therapy drive benefit — with further meta-analyses confirming gains in insomnia patients with comorbid mental disorders or chronic disease, and improved quality of life. Weighing the data: Cognitive Behavioral Therapy looks well-supported and consequential — the evidence is rated strong (90/100) and its estimated impact on longevity is also rated highly (78/100), making it one of the more solidly-backed choices on Vitaebase.
