An Inventory of Problems (IOP) Study of Symptom and Performance Validity in a Sample of Driver’s License Renewal or Reinstatement Applicants
Bibliographic record
Abstract
Abstract This study aimed to investigate the specificity of the Inventory of Problems (IOP) tests, specifically the IOP-29 and its memory module (IOP-M), in a high-stakes environment. The study involved 114 Italian adults who applied for the renewal or reinstatement of their driver’s license after it had been revoked due to psychiatric, cognitive, or legal issues. The IOP-29 and the IOP-M were administered alongside other tests. Data analysis revealed very few positive results for both the IOP-29 and the IOP-M, indicating high specificity in detecting a possible negative response bias. In fact, the false positive rate (or, more accurately, the presumably false positive rate) was less than 5% for each of the two IOP components, meaning that the specificity for the standard cutoff values of each IOP component (i.e., IOP-29 ≥ 0.50 and IOP-M ≤ 29) was above 0.95. Taken together, these results contribute to the growing body of research supporting the use of the IOP-29 and IOP-M in applied settings where mild cognitive impairment might be present. However, further studies are needed to validate these results in populations with moderate or severe cognitive impairment.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
