Development of the Quality of Life in Epilepsy Inventory
Abstract
Summary: We developed an instrument to measure health‐related quality of life (HRQOL) in epilepsy. A 99‐item inventory was constructed from the RAND 36‐Item Health Survey (generic core), with 9 additional generic items, 48 epilepsy‐targeted items, and 6 other items concerning attitudes toward epilepsy and self‐esteem. We administered the 99‐item inventory to 304 adults with epilepsy at 25 epilepsy centers. Patients and patient‐designated proxies completed the inventory and were retested 1–91 days later. A multitrait scaling analysis of these data led to retention of 86 items distributed in 17 multiitem scales (Cronbach's alpha ranged from 0.78 to 0.92). Factor analysis of the 17 multiitem scales yielded four underlying dimensions of health: an epilepsy‐targeted dimension, a cognitive factor, mental health, and physical health. Construct validity was supported by significant patient‐proxy correlations for all scales and correlations between neuropsychologic tests and self‐reported emotional and cognitive function (all p values < 0.05). There were significant negative correlations between the four factor scores derived from the HRQOL scales and neurotoxicity, systemic toxicity, and health care utilization (except for the correlation between mental health factor and health care utilization; all p values < 0.05). Patients who were seizure‐free in the preceding year reported better HRQOL for the overall score, three of the four factor scores, and 8 of the 17 scale scores than did patients with a high frequency of seizures. Relative validity analysis showed that the epilepsy‐targeted factor and three of its four component scales were more sensitive to categorization of patients by severity of seizure frequency and type than scales tapping physical health, mental health, or cognitive function. These cross‐sectional data support the reliability and validity of this measure of HRQOL in epilepsy. The addition of an epilepsy‐targeted supplement to the generic core improved the sensitivity to severity of epilepsy. The 86 items included in the field testing were supplemented by three additional items to form the Quality of Life in Epilepsy (QOLIE‐89) inventory.

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.
