*Significant difference across the three BPD subgroups at the .05 level, two-sided test
1
Based on the Sheehan Disability Scales (SDS)24. Respondents were assigned their highest rating of impairment across the four SDS domains
2
Significance of differences across three BPD subgroups in Part II was evaluated for cumulative categories. In the case of moderate severity, the BPD subgroups were compared for prevalence of severe or moderate. In the case of mild severity, the subgroups were compared for prevalence of any severity (i.e., severe, moderate or mild) versus none.
