A short form of the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE): development and cross-validation

Jorm, A. F.·1994·Psychological Medicine

Abstract

Synopsis: Data from four studies were used to assess the psychometric properties of the 26 IQCODE items. The items were assessed in terms of item–total correlations, test–retest reliabilities, correlations with indicators of current cognitive functioning and correlations with indicators of pre-morbid cognitive functioning. These data were used to develop a 16-item short form. The short form was cross-validated in a new sample using dementia/delirium diagnosis as the validity standard. It was found to perform as well as the long form.

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.
