The unstandardized coefficient Β represents the direct contribution of each variable to the dependent variable, while the standardized beta coefficient is obtained when the direct contributions are converted to typical contributions (standard deviations of the dependent variable), which permits to determine the relative value of each variable in relation to the dependent variable. R of the model for men: 0.505, R2 = 0.255. R of the model for women: 0.524, R2 = 0.275. * Somatization was not included in these analyses, considering that this variable, rather than a cause, is a consequence of the number of diseases.
