Cultural adaptation and validation of the Neuropathy - and Foot Ulcer - Specific Quality of Life instrument (NeuroQol) for Brazilian Portuguese - Phase 1

This methodological study aimed to adapt the Neuropathy - and Foot Ulcer - Specific Quality of Life instrument - NeuroQol to Brazilian Portuguese and to analyze its psychometric properties. Participants were 50 people with peripheral diabetic neuropathy and foot ulcers. The floor and ceiling effects, the convergent and discriminant validity and the reliability were analyzed. The Cronbach’s alpha coefficient was used to test the reliability and the Pearson’s correlation coefficient to estimate the convergent validity, the Student’s t test was used to evaluate the discriminant validity in the comparison of the NeuroQol scores between participants with and without ulcers. Floor and ceiling effects were found in some domains of the NeuroQol. The reliability was satisfactory. The correlations between the domains of the NeuroQol and the SF-36 were negative, significant and of moderate to strong magnitude. The findings show that the Brazilian version of the NeuroQol is reliable and valid and may be employed as a useful tool for improving nursing care for people with DM.

St George's Respiratory Questionnaire

Tuberculosis (TB) is one of the disease as the highest contributor to the disease burden in Indonesia. Tuberculosis can affect the patients’ quality of life, such as psychological, physical, and social functioning. St. George's Respiratory Questionnaire (SGRQ) is a special instrument which was widely used to measure the patients’ quality of life with respiratory disease. The objective of this study was to validate the Indonesian version of the SGRQ as instrument to collect data. A descriptive cross section design with 61 subjects was conducted at the Pulmonary Clinics and Primary Health Centers in the region of Yogyakarta within 3 months. The validation process included the known group validity, convergent and discriminant validity and factor analysis. There were 14 items question numbers which did not meet the criteria for convergent validity and 9 items which did not meet the criteria for discriminant validity. Known group validity analysis on gender showed that of the three domains of SGRQ, the activity domain gave statistically significant result. The factor analysis showed the result of Kaiser Meyer Olkin analysis (KMO) was less than 0.5. With a few modifications, the Indonesian version of SGRQ is valid and reliable for measuring quality of life in tuberculosis patients.

Abstract Aim: This study assessed the responsiveness and convergent validity of two preference-based measures; the newly developed cancer-specific EORTC Quality of Life Utility Measure-Core 10 dimensions (QLU-C10D) relative to the generic three-level version of the EuroQol 5 dimensions (EQ-5D-3L) in evaluating short-term quality-of-life outcomes/utilities after esophagectomy.Methods: Participants were enrolled in a multicentre 2×2 factorial randomised controlled trial to determine the impact of preoperative and postoperative immunonutrition versus standard nutrition in patients with esophageal cancer. Quality-of-life was assessed seven days before and 42 days after esophagectomy. Standardized Response Mean and Effect Size were calculated to assess responsiveness. Ceiling effects for each dimension were calculated as the proportion of the best level responses for that dimension. Convergent validity was assessed using Spearman’s correlation and the level of agreement was explored using Bland–Altman plots. Regression analysis was performed to identify which demographic and clinical factors influenced quality of life. Results: Respondents were 164, predominantly male (81%) with mean age of 63 years. Quality-of-life significantly reduced on both measures with large effect sizes (>80), and greater mean difference on QLU-C10D. Ceiling effects were observed with social activities (86%), mobility (67%), anxiety (55%) and pain (19%) dimensions on EQ-5D-3L. For QLU-C10D ceiling effects were observed with emotional function (53%), physical function (16%), nausea (35%), sleep (31%), bowel problems (21%) and pain (20%). A strong correlation (r=0.71) was observed between EQ-5D-3L anxiety and QLU-C10D emotional function dimensions. Good agreement (3.7% observations outside the limits of agreement) was observed between the utility scores. Blood loss and blood transfusion predicted EQ-5D-3L utility while smoking and tumour length >3cm were predictive of QLU-C10D utility. Changes in QLQ-C30 dimensions of emotional function, role function and pain were predictive of changes in EQ-5D-3L utility while changes in physical, social and role function as well as all the symptom scales were predictive of change in QLU-C10D utility. Conclusion: Although there is strong agreement between utility scores, QLU-C10D was more sensitive to short-term utility changes following esophagectomy. Cognisant of requirements by policy makers to apply generic utility measures in cost effectiveness studies, disease-specific measures should be used alongside the generic measures. Trial registrationThe trial was registered with the Australian New Zealand Clinical Trial Registry (ACTRN12611000178943) on the 15th February 2011.

The Impact

Abstract Aim This study assessed the responsiveness and convergent validity of two preference-based measures; the newly developed cancer-specific EORTC Quality of Life Utility Measure-Core 10 dimensions (QLU-C10D) relative to the generic three-level version of the EuroQol 5 dimensions (EQ-5D-3L) in evaluating short-term health related quality of life (HRQoL) outcomes after esophagectomy. Methods Participants were enrolled in a multicentre randomised controlled trial to determine the impact of preoperative and postoperative immunonutrition versus standard nutrition in patients with esophageal cancer. HRQoL was assessed seven days before and 42 days after esophagectomy. Standardized Response Mean and Effect Size were calculated to assess responsiveness. Ceiling effects for each dimension were calculated as the proportion of the best level responses for that dimension at follow-up/post-operatively. Convergent validity was assessed using Spearman’s correlation and the level of agreement was explored using Bland–Altman plots. Results Data from 164 respondents (mean age: 63 years, 81% male) were analysed. HRQoL significantly reduced on both measures with large effect sizes (> 0.80), and a greater mean difference (0.29 compared to 0.16) on QLU-C10D. Both measures had ceiling effects (> 15%) on all dimensions at baseline. Following esophagectomy, ceiling effects were observed with self-care (86%), mobility (67%), anxiety/depression (55%) and pain/discomfort (19%) dimensions on EQ-5D-3L. For QLU-C10D ceiling effects were observed with emotional function (53%), physical function (16%), nausea (35%), sleep (31%), bowel problems (21%) and pain (20%). A strong correlation (r = 0.71) was observed between EQ-5D-3L anxiety and QLU-C10D emotional function dimensions. Good agreement (3.7% observations outside the limits of agreement) was observed between the utility scores. Conclusion The QLU-C10D is comparable to the more widely applied generic EQ-5D-3L, however, QLU-C10D was more sensitive to short-term utility changes following esophagectomy. Cognisant of requirements by policy makers to apply generic utility measures in cost effectiveness studies, the disease-specific QLU-C10D should be used alongside the generic measures like EQ-5D-3L. Trial registration: The trial was registered with the Australian New Zealand Clinical Trial Registry (ACTRN12611000178943) on the 15th of February 2011.

ABSTRACT Objective To evaluate the psychometric properties of the seven theoretical models proposed in the literature for European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), when applied to a sample of Brazilian cancer patients. Methods Content and construct validity (factorial, convergent, discriminant) were estimated. Confirmatory factor analysis was performed. Convergent validity was analyzed using the average variance extracted. Discriminant validity was analyzed using correlational analysis. Internal consistency and composite reliability were used to assess the reliability of instrument. Results A total of 1,020 cancer patients participated. The mean age was 53.3±13.0 years, and 62% were female. All models showed adequate factorial validity for the study sample. Convergent and discriminant validities and the reliability were compromised in all of the models for all of the single items referring to symptoms, as well as for the “physical function” and “cognitive function” factors. Conclusion All theoretical models assessed in this study presented adequate factorial validity when applied to Brazilian cancer patients. The choice of the best model for use in research and/or clinical protocols should be centered on the purpose and underlying theory of each model.

The Impact

The Prolapse Quality of Life Questionnaire (P-QoL) is a specific questionnaire created to assess the impact of pelvic organ prolapse on women’s quality of life. The aim of the present study was to cross-culturally adapt and assess the psychometric properties of the P-QoL for Spanish women. The cross-cultural adaptation was conducted by a standardized translation/back-translation method. Psychometric analysis was performed by assessing the validity, reliability, responsiveness and feasibility. A total of 200 Spanish women were recruited and assigned to symptomatic and asymptomatic groups. The Spanish P-QoL version demonstrated good content validity. Convergent validity showed high intercorrelations with the Pelvic Floor Distress Inventory short form and the Pelvic Floor Impact Questionnaire short form. The discriminant validity showed statistically significant differences between the symptomatic and the asymptomatic groups. The internal consistency was high and of acceptable values. The test-retest reliability was shown to be high in all the cases. Regarding responsiveness, the effect size and standardized response mean demonstrated moderate values. The average time for administration was 10 (3) min. The Spanish P-QoL showed considerable support for the appropriate metric properties of validity, reliability, responsiveness and feasibility to evaluate the symptom severity and its impact on the quality of life in Spanish women with urogenital prolapse.
