Multiple regression analysis using Stata 9 and crude
analysis of the outcome (depression) with each of the
independent variables were performed. Those presenting
p < 0.20 were included in the multivariate model according
to the Stepwise Forward method, when the association
between depression and high level of work stress was
adjusted for all independent variables. It was maintained
in the analysis, those with p < 0.20 or that fitted to the
measurements obtained from another dimension.
