Standard Psychometric Criteria for Measurements in Physical and Rehabilitation Medicine
Bibliographic record
Abstract
ABSTRACT: Measurements of person's variable, such as behavior, perceptions, or attitudes, are essential to physical and rehabilitation medicine in both clinical practice and research. These measurements are commonly based on cumulative questionnaires and follow special statistical rules, belonging to the domain of psychometrics. Selecting the most appropriate measurement is critical. This article provides an overview of the standard psychometric criteria to consider in measurement selection. The article focuses on the criteria related to the contemporary psychometric approach as it considers the construct, the target population, and the purpose for which measurements are used. Common strategies related to psychometric testing are discussed and applied to critically appraise, as a representative example, one of the most commonly used pain measurements: Brief Pain Inventory. The measurement construct, conceptual framework, target population, purpose, and psychometric properties are highlighted. Observed limitations for its implementation in different settings also are discussed.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
