Abstract Background: Recently a comprehensive and multi-diversionary scale for assessing Quality of Life (QoL) in Patients with Lupus has been developed. This study aimed to evaluation psychometric properties of the Persian version of Lupus Erythematosus Quality of Life Questionnaire (LEQoL) in Iranian patients with Lupus Erythematosus.Method: We used the forward-backward translation, and cognitive interview for linguistic translation. A cross-sectional design was utilized. We recruited a convenience sample of 165 lupus patients aged 19 years or over from the Iranian social media and Tehran city rheumatology clinics. Patients completed the 36-Item Short Form Survey (SF-36), The Symptom Checklist-90-R (SCL-90-R), and the translated LEQoL. The psychometric properties of the LEQoL were examined to establish test-retest reliability, internal consistency with Cronbach's alpha coefficient (COA), divergent-convergent validity, and construct validity. Also, we used Confirmatory factor analysis (CFA) and exploratory factor analysis (EFA) for assessing factor structures.Results: The total COA was α = 0.86. All subscales internal consistency ranging from 0.85–0.94. The findings of test-retest reliability for the overall scale was 0.93 and the subscales ranging between 0.82–0.92. The results from a CFA indicated that goodness‐of‐fit are satisfactory (χ2/df = 1.28, RMSEA = 0.042, CFI = 0.975). Also EFA showed that the Persian version of LEQoL with five-factor can explain 73.7% of the variances. For assessing validity, every factor of LEQoL has a correlation with some SF.36 and SCL-90-R subscales. This matrix indicates that the LEQoL subscales are somewhat independent, and this matter is one strength issue. Only depression (SCL-90 subscale) has a significant correlation with all LEQoL subscales.Conclusion: The translated Persian version of the LEQoL is a suitable scale for assessing QoL in Iranian patients with lupus.

Abstract Background and objective Quality of life (QoL) is a multi-dimensional concept and its assessment is one of important themes of care for older people. Assessing QoL in older people needs specific scales. The aim of this study was to culturally adapt and investigate the psychometric properties of the Persian version of brief Older People’s Quality of Life questionnaire (OPQOL-brief) in an Iranian older population. Methods This methodological cross-sectional study was conducted among 525 Persian-speaking older people (aged 60 and over), living in Isfahan, Iran. Translation of the OPQOL-brief questionnaire was performed using forward–backward method. Test–retest reliability was evaluated through Intra Class Correlation (ICC) coefficient and internal consistency by using Cronbach’s α. Construct validity was investigated by using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and Latent class analysis (LCA). Criterion, convergent and discriminant validities were also assessed. Results Persian version of the OPQOL-brief showed good test–retest reliability (ICC = 0.842, 95% CI = 0.73–0.91; P < 0.001). Persian OPQOL-brief scale demonstrated high internal consistency (Cronbach’s α = 0.83). It showed good discriminant validity and differentiated old patients from healthy older individuals (P < 0.001). Construct validity based on EFA led to extraction of three dimensions (“socioeconomic”, “emotional”, and “physical” well-being) and the CFA confirmed the adequacy of extracted construct from EFA (CFI = 0.909, PCFI = 0.52, PNFI = 0.5, CMIN/DF = 3.012, and RMSEA = 0.08). LCA classified participants into three classes in terms of QoL level (low (16%), middle (67%), and high (17%)). Criterion validity and convergent validity revealed significant positive correlations between OPQOL-brief and physical and psychological dimensions of the SF-36. Conclusion The Persian version of the OPQOL-brief is a reliable and valid instrument for assessing QoL with applicability in a broad range of older Persian language population.

Abstract Background Considering the importance of having a celiac disease-specific measure of the quality of life (QOL) in Persian, the present study aimed to translate the celiac disease quality of life questionnaire (CDQOL) into Persian and evaluate its psychometric properties. Methods In this cross-sectional study, the Forward–Backward translation method was used. The content validation ratio (CVR) and the content validity index (CVI) were used for content validity assessment. The construct validity was assessed by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) on 220 celiac patients who were selected randomly from the celiac disease (CD) registry database. The correlations between the result of the Persian version of CDQOL (PCDQOL), self-rated QOL, and short form-36 (SF36) were analyzed using the Pearson correlation test. The internal consistency and test–retest reliability were measured through Cronbach’s alpha and intraclass correlation coefficient (ICC). Results In the present study, 220 celiac patients with a mean age of 35.54 ± 10.29 years participated. The mean CVI, CVR, and impact score of PCDQOL were 0.98, 0.96, and 4.82 respectively. Using EFA, four factors have extracted that had a good fit in CFA (Chi-square/DF = 1.74, RMSEA: 0.08, and CFI: 0.90, and NFI: 0.90). The results showed that there was a moderate to high correlation between PCDQOL, SF36 (r: 0.587, p = 0.02), and self-rated QOL (r: 0.64, p < 0.001). The questionnaire had high internal consistency (Cronbach alpha: 0.93) and test–retest reliability (ICC: 0.96 [0.86–0.99]). Conclusion The PCDQOL questionnaire could be used by physicians and nutritionists to assess HRQOL in celiac patients in Iran.

Abstract Background Chronic urticaria is defined as the appearance of urticarial lesions and/or angioedema during a period of more than six weeks. We aimed at developing the Portuguese version of the Chronic Urticaria Quality of Life Questionnaire (CU-Q2oL) and at testing its reliability and the content, construct and criterion validity. Methods The forward-backward approach to a linguistic equivalence was followed, after which a clinical review and a cognitive debriefing with patients were performed. The intraclass correlation coefficient checked test-retest reliability with patients filling the same questionnaire with one week apart and the Cronbach’s alpha indicator assessed the internal consistency. Construct validity was tested by an exploratory factor analysis and by hypothesis tests involving sociodemographic and clinical patient characteristics, including the urticaria control test (UCT). On the other hand, criterion validity was tested through correlations with the Short-Form Health Survey SF-36, EQ-5D-5 L, and the Dermatology Quality of Life Index (DLQI). Results A total of 162 patients from seven hospital units were included. The mean (standard deviation) age was 42.6 (13.3) and 81.6% were female. CU-Q2oL was entirely filled by all respondents. Internal consistency was 0.947 for the overall score, ranging from 0.661 (limits) to 0.899 (sleep problems) and the corresponding reproducibility indicator was 0.910, based on 23 patients and ranging from 0.711 (swelling) and 0.957 (looks). Exploratory factor analysis in general confirmed the original structure originally obtained by the authors. All CU-Q2oL dimensions were highly correlated with DLQI Index and differentiated well between males and females, and between different levels of wheals and pruritus. In addition, moderate negative correlations were found between Cu-Q2oL scores and the dimensions from SF-36 and EQ-5D-5 L. Conclusions The satisfactory metric properties confirmed the cultural adaptation and validity of CU-Q2oL into Portuguese population, providing the clinicians with a valid tool to evaluate the impact of chronic urticaria on patient’s QoL and therefore adjust their treatment.

Abstract Background and objective Many studies have been conducted in Iran on the postpartum quality of life, and the majority have used the general quality of life questionnaire. With a specific tool in this context, the dimensions of maternal postpartum quality of life can be more accurately determined. The present study was conducted to determine psychometric properties and validate the Persian version of the Maternal Postpartum Quality of Life Questionnaire (MAPP-QOL). Materials and methods The present methodological study was conducted in 2018. The original version of MAPP-QOL was translated into Persian by both forward and backward translation. In a cross-sectional study, the Persian version was completed by 407 eligible postpartum women aged 18 to 47 and living in Tehran. Reliability of the questionnaire was assessed using Cronbach's alpha coefficient and test–retest. For construct validity, exploratory and confirmatory factor analyses were used. Results The MAPP-QOL showed good content validity; content validity ratio (CVR) ranged from 0.6 to 1.00, and content validity index (CVI) ranged from 0.7 to 1.00. Using exploratory factor analysis, five factors, including Socioeconomic; Relational/Family-Friends; Psychological/Baby; Health & functioning; and Relational/Spouse-Partner, were extracted, which together explained 78.84% of the total variance. After modifications of CFA, the confirmatory factor analysis showed an acceptable goodness-of-fit. AVE value Above 0.5 exhibited appropriate convergent validity, and AVE greater than MSV confirmed divergent validity. The Cronbach's alpha, McDonald's Omega, Composite reliability and maximum reliability H of the five extracted factors were excellent (> 0.9). Also, the AIC values of the factors were good (between 0.721 to 0.859). Conclusion The 38-item Persian version of the postpartum quality of life questionnaire is adequately reliable for postpartum women in Iran. Given its appropriate psychometric properties, this scale is fit to be used in future studies on postpartum women.

The aim of the study is to determine the reliability and validity of the Greek version of the Food Allergy Quality of life Questionnaire- Child Form (FAQLQ-CF). After linguistic validation, the Greek FAQLQCF, Food Allergy Independent Measure (FAIM) and Pediatric Quality of Life Inventory (PedsQL™) were used by a physician to interview children diagnosed with food allergy and aged 8-12 via telephone. Cronbach’s alpha was used to evaluate reliability, and factor analysis to assess construct validity. The correlation between FAQLQ-CF and FAIM was moderate (rho=0.509, P&lt;0.001) and internal consistency was strong (Cronbach’s alpha 0.905). FAQLQ-CF discriminated well each question’s contribution to children’s quality of life deterioration (32- 80%), each child’s quality of life (17-89%), children differing in doing things with others (total score 3.55 vs 2.57, difference =0.98 &gt; minimal clinical importance difference = 0.5; P&lt;0.001), but not children differing in reporting anaphylaxis. The total FAQLQ-CF score correlated with the total PedsQL™ score and with the score of one of PedsQL™ subscales, demonstrating convergent validity. Factor analysis uncovered an underlying structure of four factors, explaining 50% of the variance. We can conclude that Greek FAQLQ-CF is a reliable, valid, discriminant tool for interviewing food allergic children aged 8- 12, detecting those in need for immediate care.

Patients With Epilepsy

Introduction: Epilepsy is one of the most common diseases of the central nervous system. According to the World Health Organization, it accounts for 1% of the global burden of disease worldwide. Pharmacotherapy remains the primary therapeutic tool in this disease. However, more and more emphasis is placed on approaching this group of patients in an interdisciplinary manner, taking their various needs into account: social, professional, economic or psychological. Attention is also paid to the positive impact of physical activity on the quality of life of patients with epilepsy. The patients with diagnosed epilepsy often complain of a feeling of instability not reflected in standard neurological examination. Early detection of postural control disorders is possible using an objective research tool which is the modified CTSIB test (Clinical Test of Sensory Interaction and Balance). Aim of the study: The aim of the study was to assess the influence of targeted physical therapy on the quality of life among patients with diagnosed epilepsy of unknown etiology using the SF-36 quality of life questionnaire. Materials and methods: The study included 11 professionally active adults with diagnosed generalized epilepsy of unknown etiology, treated at the Department or Outpatient Clinic of Neurology at John Paul II Specialist Hospital in Kraków. Finally, out of the 11 recruited patients (5 women and 6 men), 1 patient was excluded from the study due to a history of craniocerebral trauma. Patients were examined 3 times every month using EEG and the SF-36 quality of life questionnaire. Additionally, between the 2nd and the 3rd month of the pilot study, the study group underwent physical therapy focused on balance disorders using the Biodex SD stabilometric platform. Results: Overall, the quality of life index measured using the SF-36 quality of life questionnaire in the study group improved after the completion of targeted physical therapy. Conclusions: 1. Generalized epilepsy of unknown etiology results in a significant deterioration in the quality of life of patients, which may also be accompanied by disorders of postural control. 2 A targeted program of physiotherapy in the treatment of patients with generalized epilepsy of unknown etiology may has a positive effect on their quality of life. null

Patients with bronchiectasis feature considerable symptom burden and reduced health-related quality of life (QOL). We provide the psychometric validation of the German translation of the disease-specific Quality of Life Questionnaire-Bronchiectasis (QOL-B), version 3.1, using baseline data of adults consecutively enrolled into the prospective German bronchiectasis registry PROGNOSIS. Overall, 904 patients with evaluable QOL-B scores were included. We observed no relevant floor or ceiling effects. Internal consistency was good to excellent (Cronbach’s α ≥0.73 for each scale). QOL-B scales discriminated between patients based on prior pulmonary exacerbations and hospitalizations, breathlessness, bronchiectasis severity index, lung function, sputum volume, Pseudomonas aeruginosa status and the need for regular pharmacotherapy, except for Social Functioning, Vitality and Emotional Functioning scales. We observed moderate to strong convergence between several measures of disease severity and QOL-B scales, except for Social and Emotional Functioning. Two-week test-retest reliability was good, with intraclass correlation coefficients ≥0.84 for each scale. Minimal clinical important difference ranged between 8.5 for the Respiratory Symptoms and 14.1 points for the Social Functioning scale. Overall, the German translation of the QOL-B, version 3.1, has good validity and test-retest reliability among a nationally representative adult bronchiectasis cohort. However, responsiveness of QOL-B scales require further investigation during registry follow-up.
