In addition, differences as a function of gender were analyzed in the target variables. The study sample was made up of 137 undergraduate students before taking an exam. Our results confirm the association between sleep reduction the previous night and test anxiety as well as that between aggressiveness and test anxiety. No interaction effects were observed, but sleep reduction and aggressiveness were good predictors of test anxiety. No significant gender differences were observed in hours of sleep the previous night, aggressiveness and test-anxiety, but there were differences in anxiety as a function of the hours of sleep.  a1134-7937  a2174-0437
