An empirical study was conducted using a quantitative methodology and a ex post facto retrospective design, on one group with multiple measurements, over a sample of 263 men aged 20 to 50. The results indicated a average levels in the perception of machismo among the participants and significant relationships between a greater presence of sexist behavior and less positive traits associated with femininity expressiveness, and less use of problem-focused coping strategies. The variables that predict the perception of sexist behavior in participants were two stress management strategies: a more opened and less focused on solving problems emotional expressiveness.
