Significant difference between 12-month BPD/FME and other 12-month BPD. Significance tests were based on cumulative categories. The significance tests for “moderate” consequent compare severe-moderate versus mild-none. The models used to test the significance of these differences controlled for age and sex. In the case of the models for any BPD (i.e., BP-I/II), we also included a control for BP-I.
Clinical severity of mania/hypo-mania was assessed with a fully-structured version of the Young Mania Rating Scale. Clinical severity of MDE was assessed with the self-report version of the Quick Inventory of Depressive Symptoms. See the text for a description of cut-points. The results in Part III represent the higher of the two severity scores for respondents who had both mania/hypo-mania and MDE in the past 12 months.
Sample sizes are somewhat smaller than in Table 2 because of missing values on the severity scales.
