Objective: This study aims to demonstrate the reliability and validity of the Turkish Form of Level 2 Anxiety Scale developed according to DSM-5 criteria to measure the severity of panic disorder. Methods: This study was carried out with patients with a diagnosis of any anxiety disorder according to DSM-5 criteria who are under treatment in Celal Bayar University Faculty of Medicine Psychiatry inpatient or outpatient clinics. Patients with any mental or physical disease except for anxiety disorders were excluded. Accordingly, 54 patients with anxiety disorder were included in the study and these were distributed as panic disorder in seven patients, generalized anxiety disorder in two patients, agoraphobia in three patients, specific phobia in one patient, obsessive-compulsive disorder in two patients, somatization disorder in one patient and not otherwise specified anxiety disorder in 38 patients. As the healthy control group in 104 volunteers without any mental or physical disease were included. Beside Level 2 Anxi-ety Scale the most widely used self-rated scale, Spielberger’s State-Trait Anxiety Inventory was used for concurrent validity. In reliability analysis internal consistency coefficient and item-total correlation analysis; in validity analyses factor analysis and correlation analysis with the Spearman Correlation Analysis (SCA) was performed for validation. Results: The mean age of the study group was 28.23±11.7 years and 58.9% of the sample group (n=93) were fe-male. 64.6% of the group were college graduates, 19.0% primary school graduates, 12.7% is also high school gra-duates. Disease duration of anxiety disorder group was 17.2±11.2 years. The internal consistency of the Level 2 Anxiety Scale was 0.94 and, item-total correlation coefficients of the Level 2 Anxiety Scale were between 0.68 and 0.88. In the exploratory factor analysis, for sample adequacy Kaiser- Meier-Olkin (KMO) coefficient was calculated as 0.90 and Bartlett coefficient was 1.08. Single-factor solution was obtained and the eigenvalue was 5.26, ex-plaining 75.2% of the total variance. Factor loadings of the items were between 0.75 and 0.92. Coefficient of corre-lation analysis with SCA was calculated as r=0.45. Conclusion: These findings have been shown that the Level 2 Anxiety Scale is reliable and valid for Turkish.
