The purpose of this study was validation and examination of the PSS-14 psychometric characteristics, one of the most renowned tests measuring perceived stress, on a group of dental students (N = 250; 147 females and 103 males; Mage = 22,84; S.D. = 1,79), using descriptive, correlational and confirmatory factor analyzes (CFA). The two-factor scale structure without item 9 is supported by CFA, providing to this model a good fit. Convergent validity is supported by association with tests appreciating life satisfaction (SWLS) and depression, anxiety and stress under pressure (DASS-21R). PSS-14 shows an acceptable assessment regarding internal consistency (Cronbach’s α – 0.79 for both subscales obtained). Consequently, PSS-14 showed adequate properties for perceived stress scale assessment, so that it may contribute to the study of perceived stress for dental students.
