Empirical Validation Dataset for Cross-Panel Psychiatric State Transport and the General Psychiatric State Index

<p dir="ltr">This dataset provides derived data and empirical validation results for Cross-Panel Psychiatric State Transport (CPST) and the General Psychiatric State Index (GPSI), a framework for representing multidimensional psychiatric symptom burden as a continuous state coordinate and transporting that state across heterogeneous assessment panels.</p><p dir="ltr">The dataset contains two complementary empirical evaluations.

First, a same-participant cross-sectional bridge analysis was performed using data from 263 individuals with major depressive disorder assessed with multiple psychiatric and behavioral measures. Non-overlapping symptom panels were used to evaluate cross-panel agreement, directional invariance, holdout state reconstruction, and transport uncertainty. Second, longitudinal data containing repeated PHQ-9, GAD-7, and BDI-II assessments were used to evaluate whether within-person changes in psychiatric state were preserved across different measurement panels.</p><p dir="ltr">The package contains only derived state coordinates, change coordinates, and validation summaries; original questionnaire-level source data are not redistributed.
