Information on race and ethnicity was self-reported by participants but aggregated in a binary variable (White British; other) by clinical services before data were shared with the research team. No other details about race and ethnicity were available to the research team.
Primary diagnosis was determined using a semistructured interview supplemented by validated case-finding measures for depression (PHQ-9) and anxiety disorders (GAD-7). Cases with missing data in each feature were excluded listwise.
Scores range from 0 to 8, with higher scores indicating more personality disorder traits.

Scores range from 0 to 21, with higher scores indicating more severe anxiety symptoms.
