Abstract

MACHADO, Wagner de Lara; DAMASIO, Bruno Figueiredo; BORSA, Juliane Callegaro  and  SILVA, Joilson Pereira da. Dimensionality of the Perceived Stress Scale (PSS-10) for school teachers. Psicol. Reflex. Crit. [online]. 2014, vol.27, n.1, pp.38-43. ISSN 0102-7972.  http://dx.doi.org/10.1590/S0102-79722014000100005.

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.

Keywords : Perceived Stress Scale; PSS-10; exploratory factor analysis; parallel analysis; robust methods.
