Auditable cross-instrument detection of unusual multivariate psychiatric response configurations using a semantically aligned covariance subspace

2026-05-27

Abstract excerpt

<h4>Background</h4> Conventional psychiatric screening instruments summarize symptoms within individual scales and prioritize cases with high single-instrument additive score severity. This design treats items as independent within instruments and ignores cross-instrument covariance structure, making it insensitive to respondents whose responses are distributed across multiple domains in unusual combinations that...
