摘要：Teachers´ stress has been widely studied, but the focus has been predominantly in dysfunctional aspects. Several studies point out that stress can be a positive psychological response to a stressor, referred as eustress (Campbell -Quick, Cooper, Nelson, Quick, & Gavin, 2003; Simmons & Nelson, 2001; Simmons, Nelson, & Quick, 2003). A sample of 496 Portuguese teachers was evaluated and the main aim of the study was to adapt and validate the eustress scale developed by O'Sullivan (2011) for Portuguese teachers. The results show that this scale has adequate psychometric properties with a high value of internal consistency (α = .93), similar to the results of a previous independent sample (Fonseca & Jordão, 2011). The factor that resulted from the exploratory factor analysis explains 78,87% of the total variance. More studies should be conducted to validate the eustress scale, in teachers and also the general Portuguese population, to examine, in particular, the stability of this scale.
