Abstract

BACKGROUND: Because there is no muscle disease specific measure of quality of life (QoL), we wanted to develop and validate an individualized muscle disease specific measure of QoL for adults suitable for both clinical and research use. METHODS: A literature review exploring QoL and its measurement resulted in the development of a theoretical model of QoL. This was used alongside qualitative interviews (n = 41) and a postal survey (n = 252) to design a questionnaire. The psychometric properties, validity (n = 95), reliability (n = 40), and responsiveness (n = 25) of the scale were assessed. RESULTS: The Individualized Neuromuscular Quality of Life questionnaire (INQoL) consists of 45 questions within 10 sections. Four of these focus on the impact of key muscle disease symptoms (weakness, locking [i.e., myotonia], pain, and fatigue), five look at the impact (degree and importance of impact) muscle disease has on particular areas of life, and one section asks about the positive and negative effects of treatment. The questionnaire is structured to allow for variations in the individual characteristics that influence quality of life. Psychometric evaluation established construct validity and test-retest reliability. A preliminary assessment of responsiveness was obtained. CONCLUSIONS: The Individualized Neuromuscular Quality of Life is a validated muscle disease specific measure of quality of life developed from the experiences of patients with muscle disease and can be used for individuals or large samples.

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.
