The present study aimed to investigate the dimensionality of the 10-item Perceived Stress Scale (PSS-10) in a sample of school teachers (N = 517). An exploratory factor analysis done by the extraction method of minimum rank factor analysis, using polychoric correlation matrix and parallel analysis criterion for factor retention, indicated a one-factor solution as the best fit to the data. The items showed adequate factor loadings and the retained factor explained 67% of common scores variance, presenting internal consistency (a = .80). This study provides validity evidences of the PSS-10 for the Brazilian context.
