The McGill Quality of Life Questionnaire-Revised (MQOL-R). Psychometric properties and validation of a Brazilian version on palliative care patients: a cross-sectional study.

ABSTRACT: BACKGROUND:To assess the psychometric properties, including internal consistency, construct validity, criterion validity, criterion-group validity, and responsiveness, the Reviewed McGill Quality of Life Questionnaire (MQOL-R), into Brazilian Portuguese-(BrP). Also, to analyze the relationship of the BrP-MQOL-R with the scores on the Karnofsky Performance Scale (KPS) and on the Numerical Pain Scale (NPS 0-10). METHODS:The BrP-MQOL-R was administered to a sample of 146 adults (men?=?78). A team of experts translated the MQOL-R according to international guidelines. Convergent validity and Confirmatory factor analysis (CFA) was performed. RESULTS:The BrP-MQOL-R Cronbach's alpha was 0.85. CFA supported the original four-factor structure, with the following revised model fit-indices: PCLOSE?=?0.131, Tucker-Lewis Index (TLI) rho 2?=?0.918, incremental fit index (IFI) delta 2?=?0.936. The convergence validity is supported by a significant correlation between BrP-MQOL-R total scores and their subscales with KPS and with the single item related to the quality of life. And by a converse correlation with the pain scores in the NPS (0-10). Receiver operator characteristics (ROC) analysis showed subjects with KPS equal to or lower than 30% could be discriminated from those with scores on KPS higher than 30% by an area under the curve (AUC)?=?0.71, sensitivity?=?97%, and specificity?=?92%). CONCLUSION:The BrP-MQOL-R proves to be a reliable instrument for assessing the quality of life (QOL) in palliative care (PC), with primary evidence of validity. BrP-MQOL-R presented adequate discriminate properties to identify distinct conditions that impact the QOL in PC.

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:Emotions play a central role in scientific models of decision-making, human development, interpersonal processes, psychopathology, and well-being. The Emotional Style Questionnaire (ESQ) is a novel and multifaceted psychometric scale that assesses the dimensions of individual's emotional styles. The present study evaluated the validity and factor structure of the Persian ESQ. The original version of the ESQ was translated and back-translated into Persian, followed by a pilot study. A sample of university students and staff participated in a survey (n = 822) which included the ESQ, Overall Anxiety Severity and Impairment Scale (OASIS), World Health Organization Quality of Life Brief Version (WHOQOL-BREF), Difficulties in Emotion Regulation Scale (DERS), and Positive and Negative Affect Schedule (PANAS). Results showed that the Persian ESQ had very good internal consistency (Cronbach's alpha coefficient: 0.84; Composite reliability = 0.89) and adequate test-retest reliability after four weeks (intraclass coefficient, r = .71 with 95% CI [.63, .77]). The confirmatory factor analysis model fitted the data well (χ2/df = 2.86, CFI = .970, SRMR = .046, PCLOSE = .85 > .05, RMSEA = .048, 90% CI [.043, .053]). Also, measurement invariance indicated the ESQ had acceptable construct validity among different groups. As for criterion-related validity, the ESQ positively correlated with scores on the WHOQOL-BREF (r = .76) and PANAS-positive affect (r = .62), and negatively correlated with the scores on the OASIS (r = -.68), DERS (r = -.39), and PANAS-negative affect (r = -72). The findings provide evidence that the ESQ is a reliable and valid instrument for assessing healthy emotionality among Persian speaking individuals. The Persian ESQ can be used in psychological intervention and clinical research in Iran and other Persian-speaking countries.Supplementary informationThe online version contains supplementary material available at 10.1007/s12144-020-01205-1.
