2.2.4 Anxiety Sensitivity Index-3 (ASI-3)
The ASI-3 was originally developed by Taylor et al.13to evaluate how sensitive individuals are to their own anxiety symptoms and experiences. The validity and reliability studies of the scale in the Turkish population were conducted by Mantar et al.14. It is an 18-item self-report questionnaire consisting of six items in three subscales: physical, social, and cognitive concerns. The scores are ranged on a 5-point Likert-type scale and higher scores indicate the higher anxiety sensitivity.
