Abstract
OBJECTIVE: To validate a complex association between schizophrenia and obsessive-compulsive disorder (OCD). METHOD: We used the Structured Clinical Interview for DSM-IV Axis I disorders to compare the rate of OCD spectrum and additional Axis I disorders in 100 patients who met criteria for both schizophrenia and OCD, non-OCD schizophrenia (n = 100), and OCD (n = 35). RESULTS: There was a robust between-group difference in the number of patients with one or more OCD spectrum disorders (schizo-obsessive n = 30, compared with schizophrenia n = 8; P = 0.001), that is, higher rates of body dysmorphic (8% compared with 0%) and tic (16% compared with 4%) disorders. No difference was revealed in affective, anxiety, and substance use disorders. We found comparable rates of OCD spectrum disorders in the schizo-obsessive and OCD groups (30% and 42.8%, respectively; P = 0.32). CONCLUSION: Preferential aggregation of OCD spectrum disorders in the schizo-obsessive group supports this unique clinical association. Whether a schizo-obsessive interface represents comorbidity or a specific subtype of schizophrenia warrants further investigation.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
