This article aims to validate the factorial structure of the perceived stress scale (PSS10) within the French working population. The analyses conducted confirmed the presence of two distinct factors, interpreted in terms of perceived work overload and perceived personal efficacy. Both factors presented good internal consistency and adequate validity of construct. The authors show and illustrate the predicted link between the two factors and the levels of anxiety and depression. Thus, the PSS 10 is a bi-dimensional scale with satisfactory psychometric proprieties. The results are discussed in the light of their theoretical and practical implications.
