Psychometric properties and cross-language equivalence of the revised Bristol Rheumatoid Arthritis Fatigue and the Rheumatoid Arthritis Impact of Disease scales in rheumatoid arthritis.

ABSTRACT:

Objective

To assess psychometric properties and cross-language measurement equivalence of six versions of the Bristol Rheumatoid Arthritis Fatigue Scale (BRAF-MDQ) and the Rheumatoid Arthritis Impact of Disease Score (RAID in rheumatoid arthritis (RA).

Methods

Both questionnaires were completed by French (n?=?206), German (n?=?206), Dutch (n?=?317), Spanish (n?=?157), Swedish (n?=?170) and UK (n?=?210) RA patients. The presence of cross-language differential item functioning (DIF) was examined using the generalized partial credit model. The impact of DIF on the item and total scores was examined by comparing DIF unadjusted and DIF adjusted expected item and scale scores. IRT-based methods were used to assess psychometric properties of the instruments.

Results

11 of the 20 BRAF-MDQ (55%) and 4 of the 7 RAID items (57%) exhibited significant DIF in at least one of the six countries. The mean number of items with DIF per country was 2.6 for BRAF-MDQ and 1.1 for RAID. However, the impact of DIF on the total RAID and BRAF-MDQ scores, as well as the BRAF subscales, was found to be negligible at the group level. Only for the BRAF physical subscale was there evidence of minor DIF. Marginal reliabilities of BRAF-MDQ (0.93) and RAID (0.89) were excellent, and precise scores could be obtained across the spectrum of disease impact and fatigue scores measured by these PROMs.

Conclusion

This study supports the cross-language measurement equivalence of BRAF-MDQ and RAID and provides further support for the psychometric properties of these measures in RA.

Project description:INTRODUCTION: The Fibromyalgia Impact Questionnaire (FIQ) is a commonly used instrument in the evaluation of fibromyalgia (FM) patients. Over the last 18 years, since the publication of the original FIQ, several deficiencies have become apparent and the cumbersome scoring algorithm has been a barrier to widespread clinical use. The aim of this paper is to describe and validate a revised version of the FIQ: the FIQR. METHODS: The FIQR was developed in response to known deficiencies of the FIQ with the help of a patient focus group. The FIQR has the same 3 domains as the FIQ (that is, function, overall impact and symptoms). It differs from the FIQ in having modified function questions and the inclusion of questions on memory, tenderness, balance and environmental sensitivity. All questions are graded on a 0-10 numeric scale. The FIQR was administered online and the results were compared to the same patient's online responses to the 36-Item Short Form Health Survey (SF-36) and the original FIQ. RESULTS: The FIQR was completed online by 202 FM patients, 51 rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE) patients (31 RA and 20 SLE), 11 patients with major depressive disorder (MDD) and 213 healthy controls (HC). The mean total FIQR score was 56.6 +/- 19.9 compared to a total FIQ score of 60.6 +/- 17.8 (P < 0.03). The total scores of the FIQR and FIQ were closely correlated (r = 0.88, P < 0.001). Each of the 3 domains of the FIQR correlated well with the 3 related FIQ domains (r = 0.69 to 0.88, P < 0.01). The FIQR showed good correlation with comparable domains in the SF-36, with a multiple regression analysis showing that the three FIQR domain scores predicted the 8 SF-36 subscale scores. The FIQR had good discriminant ability between FM and the 3 other groups; total FIQR scores were HC (12.1 +/- 11.6), RA/SLE (28.6 +/- 21.2) and MDD (17.3 +/- 11.8). The patient completion time was 1.3 minutes; scoring took about 1 minute. CONCLUSIONS: The FIQR is an updated version of the FIQ that has good psychometric properties, can be completed in less than 2 minutes and is easy to score. It has scoring characteristics comparable to the original FIQ, making it possible to compare past FIQ results with future FIQR results.

Project description:BackgroundThe important role of leaders in the translation of health research is acknowledged in the implementation science literature. However, the accurate measurement of leadership traits and behaviours in health professionals has not been directly addressed. This review aimed to identify whether scales which measure leadership traits and behaviours have been found to be reliable and valid for use with health professionals.MethodsA systematic review was conducted. MEDLINE, EMBASE, PsycINFO, Cochrane, CINAHL, Scopus, ABI/INFORMIT and Business Source Ultimate were searched to identify publications which reported original research testing the reliability, validity or acceptability of a leadership-related scale with health professionals.ResultsOf 2814 records, a total of 39 studies met the inclusion criteria, from which 33 scales were identified as having undergone some form of psychometric testing with health professionals. The most commonly used was the Implementation Leadership Scale (n = 5) and the Multifactor Leadership Questionnaire (n = 3). Of the 33 scales, the majority of scales were validated in English speaking countries including the USA (n = 15) and Canada (n = 4), but also with some translations and use in Europe and Asia, predominantly with samples of nurses (n = 27) or allied health professionals (n = 10). Only two validation studies included physicians. Content validity and internal consistency were evident for most scales (n = 30 and 29, respectively). Only 20 of the 33 scales were found to satisfy the acceptable thresholds for good construct validity. Very limited testing occurred in relation to test-re-test reliability, responsiveness, acceptability, cross-cultural revalidation, convergent validity, discriminant validity and criterion validity.ConclusionsSeven scales may be sufficiently sound to be used with professionals, primarily with nurses. There is an absence of validation of leadership scales with regard to physicians. Given that physicians, along with nurses and allied health professionals have a leadership role in driving the implementation of evidence-based healthcare, this constitutes a clear gap in the psychometric testing of leadership scales for use in healthcare implementation research and practice.Trial registrationThis review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) (see Additional File 1) (PLoS Medicine. 6:e1000097, 2009) and the associated protocol has been registered with the PROSPERO International Prospective Register of Systematic Reviews (Registration Number CRD42019121544 ).
