Abstract Study Design Narrative review of the literature. Objectives Determine if the term cognitive behavioral therapy (CBT) is useful in clinical care and research. What literature supports these variables being relevant to the experience of chronic pain? What effects of CBT in treating these factors have been documented? What methods and platforms are available to administer CBT? Methods Chronic low back pain (CLBP) is a complex neurologic disorder with many components. CBT refers to a broad family of therapies that address both maladaptive thoughts and behaviors. There are several ways to deliver it. CLBP was broken into five categories that affect the perception of pain, and the literature was reviewed to see the effects of CBT on these variables.

Therefore, looking at CBT in the treatment of CLBP may provide limited clinically useful Background of Cognitive Behavioral Therapy information. The origins of CBT began with Albert Ellis in the 1950s. He is Indeed an extensive Cochrane review concluded: “There is considered one of the most influential psychologists in history, no need for more general RCTs [randomized controlled trials] publishing over 800 peer-reviewed papers.
