Abstract Introduction Psoriatic arthritis (PsA) is a multifaceted inflammatory disease that can cause joint destruction and impair quality of life. The Psoriatic Arthritis Quality of Life Questionnaire (PsAQoL) was the first disease-specific tool for determining the impact of the disease on the quality of life of people with PsA. Objectives The primary objective was to develop and validate a Brazilian Portuguese version of the PsAQoL. Methods The UK PsAQoL was translated into Brazilian Portuguese using two translation panels. This translation then checked for face validity and construct validity with new samples of patients. Finally, a test-retest validation study was conducted with 52 patients with PsA. The survey included the Nottingham Health Profile (NHP) as a comparator instrument. Results Internal consistency and reproducibility were both excellent for the new adaptation (0.91 and 0.90 respectively Scores on the PsAQoL were found to correlate as expected with the comparator measure and the instrument was able to detect differences in score related to perceived severity of PsA, general health status and presence of a flare. Conclusion The Brazilian PsAQoL was found easy to understand and complete and has excellent reliability and construct validity. The new measure will be a valuable new tool for use in routine PsA practice and clinical trials.

The Impact

Background: Different questionnaires have been developed to measure quality of life (QoL) in patients with food allergy. Our aim was to validate a Spanish translation of the Food Allergy Independent Measure (FAIM) and the EuroPrevall Food Allergy Quality of Life Questionnaire—Child Form (FAQLQ-CF) for children aged 8–12 years.Methods: Sixty children with a diagnosis of IgE-mediated allergy to food completed the questionnaires. The internal consistency was evaluated with Cronbach’s alpha. The correlation of FAQLQ-CF with FAIM was assessed to test construct validity. We compared both values with the diagnosis of anaphylaxis to evaluate discriminant validity.Results: Cronbach’s alpha was in the range of 0.654–0.863 for the four domains of FAQLQ-CF and 0.779 for FAIM. There were no criteria to remove questions from the questionnaires. Significant correlations could be found between FAQLQ-CF and the number of offending foods and the impact on social life (all r > 0.33, P < 0.01), and between FAIM and anaphylaxis.Conclusions: The Spanish translation of FAQLQ-CF showed acceptable internal consistency, good construct validity, and capacity to discriminate patients depending on the number of foods to avoid and the impact on social life. FAIM showed good discriminant capacity for anaphylaxis.

The Impact

Attempted to evaluate and compare the impact on quality of life of occupational and non-occupational ACD and to identify the most frequently involved allergens. A quality of life questionnaire was applied. We noted moderate impact on the quality of life of both groups, without a statistical difference. Our study corroborates previous general data on the prevalence of nickel sulphate and paraphenylenediamine as the most common allergens. Potassium bichromate was shown to be one of the main occupational allergens and thimerosal as the main non-occupational allergen in our sample.

Backround/Aim. Considering the distinct increase in the incidence of oropharyngeal cancer over oral cavity cancers and changing epidemiology with human papilloma virus (HPV) infection emerging as an important risk factor, there is a need to establish better treatment choices in specific groups of patients with oropharyngeal cancer. The aim of this study was to assess the quality of life (QOL) and functional performance and the impact of different demographical data, stage of disease, and treatment type on these parameters in patients with oropharyngeal cancer with successfully achieved locoregional control a year after the treatment. Methods. Study included 87 patients who underwent QOL and functional impairment assessment 12 to 14 months after finished oncological treatment with the following questionnaires: the European Organization for Research and Treatment of Cancer Quality-of Life-Questionnaire-C30 (EORTC QLQ-C30), European Organization for Research and Treatment of Cancer Quality of- Life Questionnaire-Head and Neck 35 (EORTC QLQ-H&N35) and The Karnofsky Performance Scale (KPS). Results. Specific groups of patients had significantly different post-treatment QOL scores. The factors associated with the worse QOL scores were female gender, not being in a partnership, level of education and HPV status. Conclusion. Clinicians should consider socioeconomic factors and HPV status in planning the recovery after treatment of patients with oropharyngeal carcinoma. Gender, education level and employment are the variables that form a certain risk profiles associated with the lower QOL.

Abstract Background: Treatment- and work-related aspects have been neglected in health-related quality of life (HRQOL) measures in multiple sclerosis (MS). We aimed to develop a brief instrument covering all important impairment-, activity-, participation-, and treatment-related aspects for use in research and practice. Methods: The 27-item Multiple Sclerosis Quality of Life Questionnaire (MS-QLQ27) was developed using open item collection, a multidisciplinary expert panel, and cognitive pretesting. It was evaluated for reliability, construct validity, and responsiveness with 100 patients presenting with relapse (84 at follow-up ~14 days later). Construct validity was analyzed by correlating the MS-QLQ27 with the disease-specific Hamburg Quality of Life Questionnaire in MS (HAQUAMS) and generic HRQOL instuments. The Expanded Disability Status Scale (EDSS) was used to analyze known-groups validity. Responsiveness was determined as the correlation of changes in MS-QLQ27 scores with changes in validation criteria. Results: Internal consistency was high (Cronbach α = 0.94 at baseline and 0.93 at follow-up). Convergent validity was supported by direction and magnitude of associations with disease-specific and generic instruments. Correlations with change in convergent criteria were strong, indicating responsiveness. The HAQUAMS showed the strongest associations with the MSQLQ27. The MS-QLQ27 showed the highest effect size compared with other patient-reported outcomes and the EDSS. It successfully distinguished between levels of disease severity. Conclusions: These results indicate that the MS-QLQ27 is a reliable, valid, and highly responsive instrument for assessing HRQOL during relapse evolution in MS. Its advantages are that it is brief yet comprehensive, covering work- and treatment-related aspects not addressed in previous measures.

Abstract BACKGROUND: To date, no disease-specific tool is available to assess the impact of Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) on Health Related Quality of Life (HRQoL). Therefore, the purpose of this study was to develop and validate a questionnaire specifically designed to this aim: the Nasal Polyposis Quality of Life questionnaire –NPQ.METHODS: According to the current guidelines, the development and validation of the NPQ occurred in two separate steps involving different groups of patients.RESULTS: In the development process of NPQ an initial list of items of 40 items was given to 60 patients with CRSwNP; the 27 most significant items were selected and converted into questions. The validation procedure involved 107 patients (mean age 52.9±12.4). NPQ revealed a five-dimensional structure and high levels of internal consistency (Cronbach's alpha 0.95). Convergent validity (Spearman’ coefficient r=0.75; p< 0.01), discriminant validity (sensitivity to VAS score), reliability in a sample of patients with a stable health status (Interclass Coefficient 0.882) were satisfactory. Responsiveness to clinical changes was accomplished. The minimal important difference was 7. CONCLUSIONS: NPQ is the first questionnaire for the assessment of HRQoL in CRSwNP. Our results provide that the new tool is valid, reliable, and sensitive to individual changes.

The objective of this study was to investigate the impairment of social and emotional functions, body image and future perspective in women with breast cancer undergoing chemotherapeutic treatment. This is a longitudinal research conducted from October 2012 to October 2013 at the chemotherapy unit of a private institution of Oncology located in Curitiba, PR, Brazil. Sociodemographic and clinical questionnaires were applied, Quality of Life Questionnaire Core 30 e Quality of Life Questionnaire – Breast Cancer Module, to 48 women subjected for the first time to chemotherapy, in three different stages of the treatment. Analysis with Friedman`s, Spearman and Kruskal-Wallis nonparametric tests was performed. Changes were observed in social function and body image, which compromised quality of life significantly. Results can subsidize the planning of and adjustments to the care provided to these women by considering the perception about the impact of therapy on QL and their perspectives.

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.
