Graves Ophthalmopathy

Abstract Purpose To develop and assess the psychometric properties of the Thai version of the Graves’ Ophthalmopathy Quality of Life (GO-QOL) questionnaire. Background Graves’ ophthalmopathy (GO) is a chronic condition that causes negative self-image and impaired visual function. These conditions impact quality of life (QOL) but are rarely documented. Graves’ Ophthalmopathy Quality of Life Questionnaire (GO-QOL) has good validity, reliability and responsiveness. In this study we developed a Thai GO-QOL questionnaire by translating the questionnaire from English to the Thai language and evaluated its reliability and validity. Patients and methods Forward and backward translations were performed independently by four translators with extensive experience in both English and Thai. Seventy patients at the thyroid clinic responded to the Thai translated version upon their first visit and again 2–3 weeks afterwards. Validity was assessed by the content validity index (CVI) and correlation with relevant clinical parameters. Reliability was evaluated by Cronbach’s alpha, the intraclass correlation coefficient, and the Bland-Altman plot. Results The Thai GO-QOL version showed high CVI (0.97) and a moderate negative correlation of the functional QOL score with disease severity (r = − 0.49), the clinical activity score (r = − 0.31), and exposure parameter (r = − 0.32). It showed good reliability with a high intraclass correlation coefficient (0.92) and high Cronbach’ s coefficient (0.86). Conclusion The Thai GO-QOL has good validity and reliability. It can be used to evaluate the quality of life of Graves’ ophthalmopathy patients as a consequence of their disease in thyroid treatment programs.

Abstract Background The Angioedema Quality of Life (AE-QoL) is the first patient reported outcome measure developed for the assessment of quality of life (QoL) impairment in patients with recurrent angioedema (RAE). This study aimed to evaluate the clinimetric properties of the AE-QoL in Thai patients and to establish categories of QoL impairment assessed by the AE-QoL. Methods The validated Thai version of the Dermatology Life Quality Index (DLQI) and Patient Global Assessment of Quality of Life (PGA-QoL) were used to comparatively evaluate the Thai version of AE-QoL. Spearman correlations between the Thai AE-QoL and two other standard measurements (DLQI and PGA-QoL) were investigated to determine convergent validity. The Thai DLQI and PGA-QoL were used to categorize patients according to their QoL. Known-group validity of the Thai AE-QoL was later analyzed. The reliability of the Thai AE-QoL was investigated using Cronbach’s alpha and intraclass correlation. Three different approaches including the distribution method, receiver operating characteristic curve analysis, and the anchor based-method were used for the interpretability. Results A total of 86 patients with RAE with a median age of 38.0 ± 15.1 years (range 18–76) were enrolled. Of those, 76 patients (88%) had RAE with concomitant wheals, and 10 patients (11.6%) had RAE only. The AE-QoL assessed RAE-mediated QoL impairment with high convergent validity and known-groups validity, high internal consistency and test-retest reliability, and good sensitivity to change. Although the AE-QoL did not differentiate between patients with moderate and large effect as measured by PGA-QoL or DLQI in this study, AE-QoL total values of 0–23, 24 to 38, and ≥ 39 could define patients with “no effect”, “small effect”, and “moderate to large effect” of RAE on their QoL, respectively. Conclusions This study supports the validity and reliability of the Thai version of the AE-QoL, which is a very different language from the original version. Categories allow to classify the effect of RAE on patients’ QoL as “none”, “small”, and “moderate to large”. Further studies are needed to confirm the applicability of AE-QoL in other Asian populations”.

BACKGROUND Constipation is a condition commonly encountered by physicians, causing a significant reduction in patients’ quality of life. Therefore, successful management of constipation should also include increase the quality of life. The Patient Assessment of Constipation Quality of Life (PAC-QOL) questionnaire is a questionnaire developed to address this issue. However, this questionnaire had not been translated into the Indonesian language. This study was aimed to adapt PAC-QOL into Indonesian culture and perform the psychometric evaluation. METHODS Translation and cultural adaptation were performed based on the linguistic validation guidelines by Acquadro et al in 2012. To perform the psychometric evaluation, a total of 64 subjects in Petamburan district in Jakarta, Indonesia, were recruited from February to March 2018. Test-retest reliability was assessed by completing the PACQOL twice with one-week interval. Subjects also completed the Short Form 36 (SF-36) Health Survey Questionnaire to assess concurrent validity. Internal consistency was analyzed with Cronbach’s alpha value (>0.7) and the intraclass correlation coefficient. RESULTS The mean (standard deviation) overall average score was 1.52 (0.66), while the Cronbach’s alpha value for the overall average score was 0.910. Concurrently, the intraclass correlation coefficient for the overall score was 0.87. Simultaneously, several experts judged content validity to be adequate. All the questions had significant correlations with their respective domains. Moreover, each domain of PAC-QOL also had a significant correlation with several SF-36 domains. CONCLUSIONS The psychometric evaluation performed in this study demonstrated that the Indonesian version of the PAC-QOL was valid and reliable, suggesting that this questionnaire can be used in daily clinical practice.

Purpose: To adapt the Rotator Cuff Quality of Life (RC-QOL) questionnaire into traditional Chinese (Chi-RC-QOL) and to evaluate the validity and reliability in patients suffering from rotator cuff pathologies in Hong Kong. Methods: The Chi-RC-QOL will be constructed using the forward-translation followed by the backward-translation method. Thirty consecutive patients with clinically and radiologically confirmed rotator cuff pathology were recruited. Descriptive statistics will be followed by validity assessment using comparison with the Constant Shoulder (CS) score, University of California Los Angeles (UCLA) Shoulder Rating Scale, and Western Ontario Rotator Cuff (WORC) score. Parametric data will be tested using Pearson’s correlation coefficient for the total scores. Reliability was assessed using a test–retest interval of 30 min. The Cronbach’s α and intraclass correlation coefficient were calculated. Results: Cronbach’s α and internal consistency scores were high for all parts of the Chi-RC-QOL, with Cronbach’s α ranging between 0.89 and 0.98. Internal consistency scores range from 0.82 to 0.92, which can be regarded as an excellent correlation. Test–retest reliability was excellent for all parts of the Chi-RC-QOL with good absolute reliability. Chi-RC-QOL correlates well with the CS score, UCLA Shoulder Rating Scale, and the WORC score, with all being statistically significant. Conclusions: The current study adapted the RC-QOL to traditional Chinese version. The analysis confirmed the validity and reliability of the Chi-RC-QOL questionnaire. Level of Evidence: III.

Background. Migraine-specific quality of life (MSQ) is a valid and reliable questionnaire. Linguistic validation of Persian MSQ questionnaire, analysis of psychometric properties between chronic and episodic migraine patients, and capability of MSQ to differentiate between chronic and episodic migraines were the aims of this study.Method. Participants were selected from four different neurology clinics that were diagnosed as chronic or episodic migraine patients. Baseline data included information from MSQ v. 2.1, MIGSEV, SF-36, and symptoms questionnaire. At the third week from the baseline, participants filled out MSQ and MIGSEV. Internal consistency (Cronbach alpha) and test-retest reproducibility (intraclass correlation coefficients) were used to assess reliability. Convergent and discriminant validities were also assessed.Results. A total of 106 participants were enrolled. Internal consistencies of MSQ among all patients, chronic and episodic migraines, were 0.92, 0.91, and 0.92, respectively. Test-retest correlation of MSQ dimensions between visits 1 and 2 varied from 0.41 to 0.50. Convergent, item discriminant, and discriminant validities were approved. In all visits MSQ scores were lower in chronic migraine than episodic migraine; however, the difference was not statistically significant.Conclusion. Persian translation of MSQ is consistent with original version of MSQ in terms of psychometric properties in both chronic and episodic migraine patients.

Objective: Recent years have shown an increase in the use of questionnaires measuring health-related quality of life to verify the quality of treatment in the field of oncology. An often used cancer-specific questionnaire is the “Quality of Life Core Questionnaire of the European Organization for the Research and Treatment of Cancer” (EORTC QLQ-C30). The purpose of this study is to analyze the psychometric properties of the EORTC QLQ-C30 (version 1) in order to determine the feasibility and appropriateness for its use in inpatient cancer rehabilitation in Germany with heterogeneous diagnoses.Methods: The questionnaire was administrated to a sample of 972 cancer patients at the beginning of treatment and to 892 patients after treatment. Besides descriptive analysis, the statistical analyses include confirmatory analysis and the multitrait/multimethod approach to test the questionnaire's postulated scale structure (factorial validity) and its reliability (internal consistencies). The analysis also includes a comparison of responsiveness indices (effect size, reliable change index) to test the sensitivity of the instrument.Results: The EORTC QLQ-C30 showed satisfactory levels of reliability and sensitivity, but the postulated scale structure could not be confirmed. The results illustrate that the varimax-rotated solution of a principal component analysis does not confirm the scale structure postulated by the authors. Correspondingly, the selected fit indices within the scope of the confirmatory factor analysis do not show satisfactory results either.Significance of results: We therefore consider version 1 of the EORTC QLQ-C30 to be only limitedly useful for the routine assessment of changes in the quality of life of cancer patients in inpatient rehabilitation in Germany, especially because of the instrument's length and possible redundancies. For this reason, a scoring procedure limited to a subset of items is suggested, revealing satisfactory to good psychometric indices. However, further psychometric tests are necessary, especially with regard to validity and sensitivity.

Abstract Background:The postpartum quality of life refers to women's understanding of their standing in the postpartum crisis that differs depending on their health status, social support, cultural status and values, attitudes, goals and standards. The present systematic review will identify, describe, and critically assess the psychometric properties of postpartum quality of life questionnaires.Methods/Design:A systematic review will be conducted in databases including PubMed, Embase, Scopus, Web of Science, PsycINFO, and CINAHL from January 2000 to January 2020. The psychometric properties (validity and reliability) of the instruments used in the primary studies will be assessed, and the selection, methodological quality assessment and data extraction processes of the studies will be independently assessed by two reviewers with expertise in conducting systematic reviews, so as to minimize potential personal bias. Eligible resources are selected after any lack of consensus is put to debate.The risk of bias is assessed using the COSMIN RISK of Bias checklist, and to evaluate the quality of the studies, the protocol is written based on the PRISMA-P1 standards. The results of the studies will be judged based on good measurement properties, and the results of all the studies are qualitatively summarized to produce a reference for the general quality of the results. The general quality of the evidence will be determined using a modified GRADE method.Discussion:This study assessed the psychometric properties of questionnaires used for assessing postpartum quality of life and its results can be used to identify the most appropriate tool for health applications in measuring postpartum quality of life.

Background: Family quality of life (FQoL), just like individual quality of life, has become a priority outcome in the policies and services received by persons with intellectual and developmental disabilities (IDD) and their families. Conceptualizing, measuring, and theorizing FQoL has been the object of investigation in recent decades. The goal of this paper is to present a revision of the Spanish Family Quality of Life Scales, the CdVF-E < 18 and the CdVF-E >18, and describe the FQoL of Spanish families with a member with IDD. Methods: The sample included a total of 548 families with a member under 18 years old and 657 families with a member over 18. Based on an Exploratory Factor Analysis (EFA) firstly and a Confirmatory Factor Analysis (CFA) secondly, the two scales’ psychometric properties were explored. Results: The CdVF-ER < 18 and the CdVF-ER > 18 comprise 5 dimensions, containing 35 and 32 items, respectively, and they show good validity and reliability. The families obtained a high FQoL score, although some differences exist between the dimensions on which families with children under and over 18 score highest and lowest. Conclusion: The characteristics of the revised scales facilitate their use by professionals, administrations, and services.
