OBJECTIVES: Social anxiety disorder (SAD) can be described as a clear and constant fear of the individual for being judged by others in the social milieu and being mocked by others. Although SAD is a treatable disorder, there is a diagnostic confusion due to many factors such as the difficulty in recognizing the symptoms of the disease. There are several scales currently available for SAD symptom measurement; however, some of them are long scales and should be answered by the patient and do not include physiologic manifestations. The Brief Social Phobia Scale (BSPS), which is a scoring system scored by the clinician, has an important place among these scales. There are three different subscales, which are fear, avoidance, and physiological symptoms on the BSPS. The aim of this study is to test the validity and reliability of the Turkish version of the BSPS.
