Research Paper on Effectiveness of Cognitive–Behavioral Therapy


CBT (cognitive–behavioral therapy) is a psychological treatment that has been shown to increase patient well-being in the context of a variety of mental and physical health issues. Thousands of randomized control trials have been conducted, with the results synthesized into hundreds of systematic reviews.

The goal of this overview is to map, synthesize, and evaluate the evidence collected from these systematic studies of CBT’s efficacy across all health problems, patient categories, and settings.

Research Paper on Effectiveness of Cognitive–Behavioral Therapy

CBT is a talking therapy that focuses on recognizing and confronting maladaptive beliefs and behaviors, as well as attempting to build new ways of thinking and acting in order to improve patients’ psychological and physical results.

CBT contains a basic set of skills that may be used across diagnoses, but it has also been adapted for specific groups, such as CBT insomnia. The majority of CBT is given in accordance with CBT procedure guidelines tailored to the health issue.

On behalf of the Department of Health, Roth and Pilling3 created a set of core competencies for CBT that includes a distinction between high and low-intensity CBT.

The high intensity was defined as formal CBT provided face to face in an individual or group style by a CBT-trained health practitioner. Low-intensity therapies emphasize patient self-help and can be administered by health professionals with varying levels of CBT expertise and on a variety of platforms.

Randomized control trials (RCTs) have been used to assess the effectiveness of CBT for a variety of medical and mental health issues, ranging from schizophrenia4 to mild back pain, and have been synthesized into systematic reviews.

We found several common themes in the CBT systematic reviews, such as relieving insomnia symptoms in individuals with a variety of health issues. However, we found places where there was inconsistent data, such as the efficacy of CBT in decreasing relapse in schizophrenia.
