For this reason, this study was oriented to determine the reliability and validity of seven subscales. We worked with a probabilistic sample of 497 public health workers (M=38 years; SD=9,48). The results indicated adequate internal consistency indexes; by means of the analysis of principal components some subscales with multifactorial structure were detected, while others retained their original structure. By means of rotation Oblimin was obtained a distribution of items consistent with the theoretical constructs, so it was concluded that their use in this population would be pertinent.</p>
