Anxiety sensitivity is an individual cognitive predisposition to arouse fear of anxiety and anxiety related symptoms. The aim of this study was to examine the psychometric properties of Anxiety Sensitivity Index (ASI) in Serbia, on the sample of a clinical and non clinical population (N=140). The sample engaged 70 participants diagnosed with anxiety disorder, and 70 of non clinical population, 27.14% male and 72.85% female, average age 40 years old. Descriptive statistics, Principal component analyisis, Cronbach’s alpha, Pearson’s coefficient of correlation (ASI with STAI-S and STAI-T) were used. The results confirmed three-factor structure of ASI (physical concern, psychological concern, social concern) with a higher-order factor. Mean value is 32.89 (SD=14.75) for participants with diagnosed anxiety disorder, and for non clinical sample is M=18.57 (SD=12.18). Cronbach’s alpha is α=0.88 (physical concern, α=0.87; Psychological concern, α=0.77; Social concern, α=0.56). Correlation between ASI and STAI-S is r=0.567 and between ASI and STAI-T is r=0.668. There are no significant differences by gender. Three-factor structure and valid psychometric properties of Serbian version of ASI, in clinical and non-clinical population, are obtained in this research and confirm the results from other reasearches worldwide. The possibility of applying anxiety sensitivity concept and measurement in sport might be of great importance
