Objective This study aims to assess the psychometric values of the Generalized Anxiety Disorder Scale-Revised (GADS-R) which
measures the intensity and duration of worry, various coping and avoidance strategies to cope with worrying, and positive and negative
metacognitive beliefs about worrying.
Methods 114 patients with generalized anxiety disorder and 198 healthy controls were included in the study. These patients were diagnosed according to DSM-IV TR, and the primary diagnosis of the patients was generalized anxiety disorder which was confirmed via
SCID I and II, subsequently. Sociodemographic form, GADS-R total and subscale scores, and Meta-Cognitions Questionnaire-30 (MCQ30), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Generalized Anxiety Disorder-7 Scale (GAD-7), and Penn State
Worry Questionnaire (PSWQ) were used to assess validity, reliability and cut-off point.
Results GADS-R total and subscale scores and MCQ-30, BDI, BAI, GAD-7, and PSWQ were found to be statistically higher in the patients with GAD compared to a healthy control group. GADS-R has five factors and showed relatively acceptable sensitivity and specificity
for detecting anxiety disorders at a cut-off point of 1188.
Conclusion The GADS-R is a valid and reliable scale that can be used in the Turkish population as an assessment tool.
