The hierarchical model with premenstrual symptoms severity as a predictor in the first step, depressive symptoms and trait anxiety were added in the second step. 95% confidence intervals are showed in brackets.
rsemi semi-partial correlation coefficient, % of variance the percent of the variance of dependent variable explained by the predictor.
Significant predictors are in bold.
