This project hosts analysis code, de-identified summary statistics, supplementary tables, and figures supporting the initial psychometric validation study (38-item core + 12-item supplementary module + 50-item childhood retrospective form; N = 747 informant-assessed adult dyads, 21 July 2026 extraction). Structural validity was examined via split-sample internal replication (polychoric EFA on Split A; WLSMV CFA on Split B and pooled sample), with internal consistency, same-informant known-groups discrimination, ROC analysis, cross-form correspondence, and preliminary within-platform cross-source convergent validity. All criterion-related estimates are provisional (same-informant criterion). ## Contents Analysis scripts (Python/R), supplementary tables (S-T1 to S-T8), EFA/CFA outputs (JSON), figures (PNG), and checklists (COSMIN, STROBE).
