Hierarchical Structure of Psychopathology in the Youth Self-Report: Testing the HiTOP Model in Peruvian University Students

Supplementary tables (Tables S1–S16) for the article “Hierarchical Structure of Psychopathology in the Youth Self-Report: Testing the HiTOP Model in Peruvian University Students.” The study evaluated five structural specifications of the Youth Self-Report (YSR) across 17,609 Peruvian youths aged 16 to 26 years entering higher education, randomly partitioned into derivation and validation subsamples (n = 8,803 and 8,806), alongside associations of the retained factors with 22 external clinical criteria. Regarding internal structure, Tables S1–S8 report item response distributions (Table S1), parallel analysis and exploratory solutions (Tables S2–S3), validation-subsample fit across all 10 confirmatory estimations alongside post-refinement changes (Table S4), item assignments and standardized loadings (Tables S5–S6), refined bifactor auxiliary indices (Table S7), and multigroup invariance across sex and age groups (Table S8). Regarding relations with external variables, Tables S9–S16 detail criterion availability and prevalence, factor score intercorrelations, group comparisons, logistic regression and receiver operating characteristic discrimination, spectrum-specific discrimination and effect sizes, a ±180-day temporal sensitivity analysis, and a robustness check using rating scale model scores.
