Inferring Depression and Its Semantic Underpinnings from Simple Lexical Choices

Figure 6

Posterior distributions of PHQ-9 sum scores predicted by subject-level semantic scores. A positive feature score indicates more distal responses for words scoring high on this feature. A negative feature score indicates more proximal responses for words scoring high on this feature. A positive regression effect indicates that higher feature scores predict higher PHQ-9 scores. A negative regression effect indicates that lower feature scores predict higher PHQ-9 scores. Orange: study 1. Blue: study 2. Black texts denote the number of words used in model estimation (the number of DCT items for which feature ratings were available).
