Setting: Although the St George's Respiratory Questionnaires in Mandarin-Chinese (SGRQ-MC) have been used in China, few data are available on the translation and adaptation process, psychometric properties and clinical meaning. Figure 1 Conceptualization of the SGRQ “Symptoms” domain. The questionnaire consists of 50 items with 76 weighted responses that produce scores in .

Karloh M, Mayer AF, Maurici R, Pizzichini MM, Jones PW, Pizzichini E. The COPD assessment test: what do we know so far? Any outstanding issues were then resolved with assistance from the sponsor, the data integration company (INC Research), or the SGRQ working group, as necessary. Longitudinally, for the integrated dataset, the correlation between change in SGRQ and FEV1 percent predicted change, r ranged from 0.10-0.27 across treatment classes (placebo, long-acting bronchodilators and inhaled corticosteroid/long-acting beta2-agonist) and follow up time between 3 and 36 months. A total of 20 eligible studies were entered in the database for analysis, aiming to balance the geographic spread of the patients, the duration of studies and the numbers of patients included from each participating company, while maintaining the required minimum data requirements for the analysis (Figure 2). The responsiveness of SGRQ-CM was assessed by calculating the effect size (ES). Description The St George's Respiratory Questionnaire (SGRQ) is a standardized self-administered disease-specific questionnaire developed by Jones et al. doi:10.1164/ajrccm/145.6.1321, 5. Three health status measures, CAT, the Malaysian version of EQ-5D-5 L, and mMRC dyspnea scale were simultaneously applied to the study population along with the SGRQ-CM. These symptoms are responsible for impaired QoL and can be assessed through communication with the patient rather than spirometry.

It can be used as a reliable QoL measure in future research, including randomized clinical trials, rehabilitation studies, and QoL studies in COPD patients. Data is available on request from corresponding author. PRO endpoints, specifically about symptoms and activity limitations, are critical for the demonstration of the benefit of new treatments in COPD clinical trials. doi:10.2147/COPD.S146390, 27. First, the SGRQ “Activity” domain covers a wide range of severity, by including a wide variety of activities, which was reflected by the breadth of the continuum resulting from the RMT analyses of this domain.

This volume brings together an international group of experts in COPD to provide in depth reviews of clinical perspectives into COPD. 13. As the response categories were not functioning as expected, a recategorization of the response scales of the six items with disordered thresholds was explored: for items 1 to 4, the two response options reflecting chest infection were grouped with “not at all” because they were conditional of having had chest infections, which was a different concept; for item 5, a category “1, 2 or 3 attacks” was created by merging the three corresponding original categories; for item 6, a category “more than 1 day, but less than 1 week” was created by merging the categories “1 or 2 days” and “3 days or more”. Interpretation of quality of life scores from the St. George's Respiratory Questionnaire. The overall objective of the present analyses was to better understand the extent to which the items composing “Symptoms” and “Activity” domains of the SGRQ form scales that can efficiently capture and meaningfully characterize treatment efficacy in clinical trials, but also exploring the variability in measurement by these domains across cultures, which can occur in large multinational clinical trials. 1991;85(Suppl 2):25-31. doi: https://doi.org/10.1016/S0954-6111(06)80166-6, 10. Mannino DM, Tal-Singer R, Lomas DA, et al. Respir Med. The scoring method used for both versions of the SGRQ provides equivalent SGRQ scores, i.e., a score range from 0 (best health status) to 100 (worst health status). Correlation of SGRQ-CM with CAT, EQ-5D-5 L, mMRC dyspnea scales and FEV1%predicted were reported as 0.86, − 0.82, 0.72 and − 0.42 respectively. SETTING: Although the St George's Respiratory Questionnaires in Mandarin-Chinese (SGRQ-MC) have been used in China, few data are available on the translation and adaptation process, psychometric properties and clinical meaning. 1992;145(6):1321–1327. Soc Sci Med. Lo C, Liang WM, Hang LW, Wu TC, Chang YJ, Chang CH. Under the consortium agreement, all data were entered by a third party and comparisons were only made at the level of drug class during analysis. Construct validity (known-group validity and reliability) was assessed by analyzing the correlation of SGRQ-CM total and subscale scores with clinical measures and other health status measures (CAT, EQ-5D-5 L and mMRC) obtained during the baseline assessment.

Among the ten measurement properties mentioned in COSMIN checklist to assess the good methodological quality of a validation study, nine (internal consistency, reliability, content validity, structural validity, hypotheses testing, cross-cultural validity, criterion validity, responsiveness and interpretability) were reported according to the set standards [45]. The SGRQ-C is a COPD specific, 40-item version of the original SGRQ and was derived following detailed analysis of data from large studies in COPD.11 The SGRQ and SGRQ-C are divided into 2 major components: Part I produces the Symptoms score, while Part 2 produces the Activity and Impacts scores; a total score is also generated. 2013;8(1):2.

Second, even though the cross-cultural examination of the SGRQ “Activity” domain did not identify a global region that was systematically different from the others, it revealed a substantial variation in how the patients respond to the SGRQ items depending on where they live. Among patients that had exacerbation data available, annual exacerbation rates ranged from 0.64 (short-term trials) to 1.59 (medium-term trials). Responsiveness can be defined as the ability of the health status measure to determine clinically meaningful changes with the passage of time or under the impact of an intervention.

SGRQ scores increased with increasing modified Medical Research Council dyspnea scores (mean differences ranged 6.9-17.9 units) and with increasing airflow limitations (Global initiative for chronic Obstructive Lung Disease grades 1 to 4; differences ranged 4.5-16.1 units), consistent across study types. The patients were included in the study if they had, (1) confirmed diagnosis of COPD (FEV1/FVC < 70), (2) minimum of six-month outpatient record to avoid abrupt changes in QoL due to initiation of therapy, (3) no changes in treatment over the past 4 weeks, (4) no other respiratory disorders, (5) no other diseases that have a short term effect on QoL, and (6) no disability. 2008; 31(4): 869-873. doi: https://doi.org/10.1183/09031936.00111707, 14. Patients with higher predicted FEV1 scores reported better QoL as compared to patients with a low predicted FEV1 score. Moreover, a significant difference in SGRQ-C scores in patients suffering from exacerbation and after one month of discharge from hospital shows that SGRQ-C can reliably identify response to therapy in COPD patients. Figure 2 Person-item distribution of the SGRQ “Activity” domain without items 11 and 17 (Baseline visits, pooled data from 5 trials, N=7,116). Factor analysis evaluates the internal structure of a questionnaire. Open access peer-reviewed scientific and medical journals. McGraw-Hill; 1994. Thorough psychometric evaluation of the Symptoms and Activity domains using modern psychometrics methods, such as Rasch measurement theory (RMT), will allow a finer understanding on how they perform6 and whether they could be good candidates to measures these two PRO domains of importance highlighted in the FDA draft guidance in COPD.2. The aim of the CBQC working group on SGRQ was to construct an individual patient level database of clinical trial data that included the SGRQ, to use this to confirm the reliability and validity of the SGRQ as an outcome measure of health status, and investigate its use as a predictor of future events (exacerbations and mortality). The St. George's Respiratory Questionnaire is a self-completed test with three components—symptoms (distress caused by respiratory symptoms), activity (disturbance in daily activities), and impact (psychosocial function)—summed to give a total score of overall health status. Copyright 2017 Informa PLC. An exploratory RMT analysis was also conducted using the different specific symptoms as defined in the reconceptualization of the SGRQ “Symptoms” domain (Figure 1). In general, QoL questionnaires are widely used to observe patient improvement, responsiveness to ongoing therapy, verify the lab test values, and effect of clinical interventions. 20 index, and the Guttman scale response pattern. The objective of our study was to develop a Malaysian version of SGRQ-C (SGRQ-CM), to evaluate the full spectrum of psychometric properties (reliability, validity and responsiveness) of the SGRQ-CM, to test the factor structure of SGRQ-CM and to assess MCID for the SGRQ-CM, to be used in population of Malaysia. MCID is the minimal difference in outcome measure that clinicians and patients would care about. It is therefore difficult to adequately evaluate the equivalence of this instrument in Chinese populations. The difference in our reported values and the original SGRQ-C may be due to difference in study population and difference in cultural values of Asian and European population. 2007;132(2):456–463. Several features of Moreover, the translation of the questionnaire to native language not only improves communication between patient and healthcare professionals, but also helps in measuring the exact experience of individuals on QoL due to influence of the disease without any interference from the health professional [14]. The St. George's Respiratory Questionnaire (SGRQ) was a widely used tool to assess disease impact on patients with obstructive airways disease. It is therefore difficult to adequately evaluate the equivalence of this instrument in Chinese populations. The St. George's Respiratory Questionnaire. 2005;2(1):75–9. Accessed February 22, 2020. doi:10.1586/erp.11.59. This study was part of a prospective cohort that included patients from the main public hospital of Penang, Malaysia. PubMed  In conclusion SGRQ-CM has a strong evidence of validity (construct and concurrent), reliability and responsiveness to disease severity in Malaysian COPD patients. Meguro M, Barley EA, Spencer S, Jones PW. The 6-minute walk test as a COPD stratification tool: Insights from the COPD Biomarker Qualification Consortium. MCID and responsiveness test results shows that it can reliably assess the impact of an intervention in COPD patients and can be used in clinical practice to measure treatment efficacy for selection of optimal treatment. A modest reliability with a PSI of 0.70 was observed. When items do not work together in this way (ie, there is item misfit), the validity of an item set is questionable. 2019;37(5):715–25. This is assessed by comparing the spread of person and item location estimates over the common continuum. Please sign up to receive your free digital subscription. A DIF is non-uniform if the difference between groups depends on the targeted concept being measured (eg, patients with low activity limitations from a given global region tend to endorse an item less than patients from other global regions while patients with high activity limitations of that same global region tend to endorse it more). The patients mostly had moderate to severe COPD and the percentage of male in our sample was slightly greater than in the general COPD population.26 Whether our results can be generalized, especially to patients with milder or very severe COPD, is an open question. St George's Respiratory Questionnaire (SGRQ) The SGRQ questionnaire has 50 items with 76 weighted responses. •  software development by maffey.com GOLD website. ES determines the magnitude of change and was calculated by using the mean difference and standard deviation (SD) at baseline and after six months of follow-up and between patients at different stages of disease severity. Found inside – Page 1Respiratory Muscle Training: theory and practice is the world’s first book to provide an "everything-you-need-to-know" guide to respiratory muscle training (RMT). It can evaluate disease symptoms, patient’s daily activity, the impact of COPD on patient’s life and total QoL score. Targeting: With the Rasch model, the parameters for items and participants are estimated in the same continuum, allowing a direct comparison of the distributions of items and participants over this common continuum. CAS  Am J Respir Crit Care Med. Secondly, our results were obtained from five trials with specific characteristics.

Different approaches are used to assess the MCID. PubMed  The translated version of the SGRQ-C questionnaire was available from the St George’s library. The MCID reported in our study is comparable to the one reported in literature. The small difference in the alpha value shows the possibility of the strong impact of culture on activity and impact subscale. RESEARCH Open Access Validation and clinical interpretation of the St George s respiratory questionnaire for COPD (SGRQ-C) after adaptation to Malaysian language and culture, in patients The st … To assess that the translated version still retains its equivalence to the original version, it was filled initially by 10 COPD patients and the patients were interviewed to probe what he/she thought about the meaning of each questionnaire. Ferrer M, Villasante C, Alonso J, Sobradillo V, Gabriel R, Vilagut G, et al. When considering the data from the observational studies in this context, it is important to appreciate that only 1 low-medium income country (Venezuela) contributed patients, this was in the BODE cohort.15 All other patients in BODE and the other 2 observational studies came from high income countries. The study sample was composed of 862 individuals. Methods Twenty Dutch COPD patients were recruited through pulmonary physicians [13 women; mean age = 63.3 years (SD = 11.4)]. In addition to the need for an updated rating schedule, this book highlights the need for the Department of Veterans' Affairs to devote additional resources to systematic analysis of how well it is providing services or how much the lives ... Chest. In EFA Six out of seven symptom items showed loading in symptom factor with a success rate of 87.5%. This book provides up-to-date knowledge on all aspects of the multidisciplinary approach to pulmonary rehabilitation that is essential in order to achieve optimal results. Further details of each included study are provided in the online data supplement Table S1. RMT analyses use a mathematical model, the Rasch model, to evaluate the extent to which items from an instrument can be summed to build a proper measurement of the underlying abstract concept.13–15 RMT analyses explore the following properties: RMT analyses were carried out using RUMM 2030 software (RUMM Laboratory, Perth, Australia) on the pooled baseline SGRQ data from the five trials (regardless of which treatment the individuals were assigned to).
