Navigate the framework

The HiTOP model organises psychopathology hierarchically — from the broadest general factor (L1) through clinical spectra (L2–L3) to specific disorders (L4). Broader levels capture shared variance across conditions; narrower levels offer disorder-specific measurement.

Distress

L1–L3 launch spectrum-wide assessments. L4 nodes launch specific disorder CATs. Hover any node for measures, time, and clinical context.
