Regression coefficients (with standard error of estimate in parentheses) from the multiple linear regression analysis. Coefficients with p<0.05 in bold. The reference score (=the intercept of the model) is the estimated score of a reference group comprising 20 year old women with more than three years of education, living with a partner and not having any depression or somatic illness. The regression coefficients estimates changes in mean score
