Systematic Review on Obsessive Compulsive Disorder and Cognitive Behavioral Therapy

This study aims to investigate the application of Cognitive Behavioral Therapy (CBT) to individuals with Obsessive Compulsive Disorder (OCD). The study was conducted using the systematic review method. No field work was conducted and no scale was used. The studies examined in Turkish and English were conducted between 2017 and 2023. This review was conducted in two stages in March 2025 and May 2025. The results obtained show that OCD symptoms are significantly reduced and in some cases completely eliminated with CBT. It was also determined that CBT reduces individuals' anxiety levels, increases their functionality, and improves their ability to cope with obsessive thoughts. The reviewed sources show that CBT applied both individually and in groups yields positive results in the treatment of OCD. As a result, CBT stands out as an effective psychotherapy method that is widely used in the treatment of OCD, is based on scientific foundations, and can provide permanent improvement in the long term. This review strengthens the role of CBT in the treatment of OCD and provides a basis for future clinical research.
