Perceived Stress Scale

The perceived stress scale (PSS-10) reliability and validity were evaluated in Brazilian adults. A two-stage translation procedure was employed to achieve a Portuguese version. Participants were 793 Brazilian university teachers. The exploratory factor analysis showed two factors with eigenvalues greater than 1.0 (56.8% of variance). The Cronbach’s alpha coefficients were 0.83 (Factor 1), 0.77 (Factor 2) and 0.87 (Total Score). The test—retest reliability scores were 0.83 (Factor 1), 0.68 (Factor 2) and 0.86 (Total Score). PSS-10 and perceived health correlations ranged from —0.22 to —0.35. The PSS-10 showed an adequate reliability and validity supporting its use in this population.
