A meta-analysis (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3584580/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3584580/) of 269 studies found it for depression to be roughly equal to medication treatment and that when combined with medication was more effective than one or the other: > Compared to pharmacological approaches, CBT and medication treatments had similar effects on chronic depressive symptoms, with effect sizes in the medium-large range (Vos, Haby, Barendregt, Kruijshaar, Corry, & Andrews, 2004). Other studies indicated that pharmacotherapy could be a useful addition to CBT; specifically, combination therapy of CBT with pharmacotherapy was more effective in comparison to CBT alone (Chan, 2006). It also found it to be effective in nicotine cessation and other addictive behaviors: > Treatments for smoking cessation found that coping skills, which were partially based on CBT techniques, were highly effective in reducing relapse in a community sample of nicotine quitters (Song, Huttunen-Lenz, & Holland, 2010), and another meta-analysis noted superiority of CBT (either alone or in combination with nicotine replacement therapy) over nicotine replacement therapy alone (Garcia-Vera & Sanz, 2006). In anxiety disorders, studies found them to be effective "first line" approaches, including when the CBT was delivered over the internet: > In general, CBT is a reliable first-line approach for treatment of this class of disorders (Hofmann & Smits, 2008), with support for significant positive effects of CBT on secondary symptoms such as sleep dysfunction and anxiety sensitivity (Ghahramanlou, 2003). Further, internet-delivered or guided self-help CBT showed some promise in immediate symptom relief as compared to no treatment, but the long-term maintenance with this modality of CBT remains unclear (Öst, 2008; Coull & Morris, 2011). Also, the meta-analysis also found it to be effective for: * insomnia * anger and aggression * general stress and many other disorders.
