A methodological framework for assessing health indices

Kirshner, Bram, Guyatt, Gordon·1985·Journal of Chronic Diseases

Abstract

Tests or measures in clinical medicine or the social sciences can be used for three purposes: discriminating between subjects, predicting either prognosis or the results of some other test, and evaluating change over time. The choices made at each stage of constructing a quality of life index will differ depending on the purpose of the instrument. We explore the implications of index purpose for each stage of instrument development: selection of the item pool, item scaling, item reduction, determination of reliability, of validity, and of responsiveness. At many of these stages, not only are the requirements for discriminative, predictive, and evaluative instruments not complementary, they are actually competing. Attention to instrument purpose will clarify the choices both for those developing quality of life measures and for those selecting an appropriate instrument for clinical studies.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
