The European Spanish versions of the 14-item and 10-item Perceived Stress Scale demonstrate adequate reliability, validity, and sensitivity for measuring perceived stress in Spanish adults.
This paper presents evidence from a heterogeneous sample of 440 Spanish adults, for the reliability and validity of a European Spanish version of the Perceived Stress Scale (PSS), designed to measure the degree to which situations in one's life are appraised as stressful. The European Spanish version PSS (14-item) demonstrated adequate reliability (internal consistency, alpha = .81, and test-retest, r = .73), validity (concurrent), and sensitivity. Additional data indicate adequate reliability (alpha = .82, test-retest, r = .77), validity, and sensitivity of a 10-item short version of the PSS.
