A Rasch Analysis of the Q-LES-Q-SF questionnaire in a cohort of patients with neuropathic pain

Popis výsledku v původním jazyce

Objectives: The purpose of this paper is to establish measurement properties of the Quality of Life Enjoyment and Satisfaction Questionnaire short form (Q-LES-Q-SF) employing the Rasch Masters Partial Credit Model. Methods: Consecutive patients with neuropathy (N = 1301) were interviewed by 86 out-patient care neurologists. The physicians recoded patients&apos; gender, age, education, main and associated diagnosis, length of main disease, the CGI-Severity scale, and patients filled up the Q-LES-Q-SF quality of life questionnaire. Results: The findings establish that (a) the instrument is unidimensional; (b) 5-point scale categories progress monotonically; (c) the construct &quot;quality of life&quot; was adequately operationalized; (d) there was neither floor nor ceiling effect; (e) the scale is acceptably well targeted; (f) there was no differential item functioning found from the viewpoint of gender, age and CGI with exception of the item reflecting sexual drive, interest and/or performance; older patients were less satisfied with their sexual life. Conclusions: Our analysis brought reliable evidence that the Q-LES-Q-SF questionnaire satisfactorily approximate resemblance between theoretical expectations of the Rasch model and our data, and that the instrument appears to be a reliable instrument for assessment of wellbeing in patients with neuropathy.
