Abstract Introduction: Cancer of the cervix has a progressive character and is one of the most significant public health problems in many countries. Our research aimed to translate EORTC QLQ CX 24 (European Organization for Research and Treatment of Cancer; Quality of life questionnaire-cervical cancer 24) from English to Serbian, to create essential cultural adaptations and to analyze psychometric properties of the translation in a model of female inpatients with cancer of the cervix. Method: The QLQ CX 24 was translated and adapted according to internationally established guidelines, and then tested on a sample of 100 Serbian females with cancer of the cervix. The testing was repeated three times on the same patients. We calculated the internal consistency (Cronbach’s alpha), criterion validity, convergent validity, and discriminative validity of the QLQ CX 24. We used factor analysis to discover the original construct. Results: The Serbian translation of QLQ CX 24 showed good internal consistency, showed satisfactory reliability, and temporal stability. In the first, when was rated by the investigators Cronbach’s alpha was 0.607, and one month later when the questionnaire also was rated by investigators Cronbach’s alpha was 0.696. When the scale was rated by females themselves Cronbach’s alpha was 0.802. Divergent as well as convergent validity tests had good results. The factorial analysis exposed six domains.Conclusion: The Serbian translation of QLQ CX 24 is a trustworthy and appropriate specific instrument for measuring the quality of life in females with cervical cancer.

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<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 > minimal clinical importance difference = 0.5; P<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.

Abstract Background Chronic conditions impose a major impact on quality of life and on healthcare. The Assessment of Burden of Chronic Conditions (ABCC-)tool was developed to improve experienced quality of care and quality of life by facilitating shared decision-making and self-management. It assesses the experienced burden of one or multiple conditions, and visualises and integrates the burden in daily care. However, its scale’s validity and reliability are yet unknown. The aim of this study is to evaluate whether the ABCC-scale is valid and reliable in people with Chronic Obstructive Pulmonary Disease (COPD), asthma, or Type 2 Diabetes Mellitus (T2DM). Methods The Saint George Respiratory Questionnaire (SGRQ), the Standardized Asthma Quality of Life Questionnaire (AQLQ-S), and the Audit of Diabetes Dependent Quality of Life Questionnaire (ADDQoL19) were compared to the ABCC-scale to assess convergent validity. Convergent validity was assumed when at least 75% of the postulated correlations were higher than 0.7, or between 0.3 and 0.7 for single-item subscales. To measure known-group validity, participants were categorized according to exacerbation status, depression, asthma control, insulin dependence, complications and obesity. The ABCC-scale was deemed internally consistency upon a Cronbach’s alpha ≥ 0.90 for the total scale, and ≥ 0.70 for subscales. Test-retest reliability was evaluated at a two-week interval. Results A total of 65, 62, and 60 people with COPD, asthma, T2DM respectively were included. The ABCC-scale correlated, in accordance with hypotheses, with the SGRQ (75%), AQLQ-S (100%), and ADDQoL19 (75%). Differentiation of known-groups based on the ABCC-scale was possible for all specified groups. The total score and subscores of the ABCC-scale were internally consistent with a Cronbach’s alpha of 0.90, 0.92, and 0.91 for the total score for people with COPD, asthma, and T2DM respectively. The ABCC-scale had a good test-retest reliability with an Intraclass Correlation Coefficient of 0.95, 0.93, and 0.95 for people with COPD, asthma and T2DM respectively. Conclusions The ABCC-scale is a valid and reliable questionnaire that can be used within the ABCC-tool for people with COPD, asthma or T2DM. Future research should indicate whether this also applies to people with multimorbidity, and what the effects and experiences are upon clinical use.

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 validation of the Farsi version of Maternal Postpartum Quality of Life (MAPP-QOL). Materials and Methods The present methodological study was conducted in 2018. The original version of MAPP-QOL was translated into Farsi by backward method. Ina cross-sectional study, the Farsi version was completed by 407 eligible postpartum women with 1-3 weeks infant, aged 18 to 47 living the city of Tehran. Reliability of the questionnaire was assessed using Cronbach's alpha coefficient and 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 were extracted, including Socioeconomic; Relational/Family-Friends; Psychological/Baby; and Health & Functioning ; relational/ spouse-partner. which together explained 78.84% of total variance. After modifications of CFA, all goodness of fit indices confirmed the model fit (χ2 = 1677.57; N = 200; df= 644, P < 0.001; PCFI = 0.831; PNFI = 0.786; CMIN/DF = 2.604; RMSEA = 0.051; IFI = 0.908, CFI = 0.907) . The Cronbach’s alpha, McDonald’s omega, Composit reliability and maximum reliability H of the five extracted factors were excellent (0.9<). Also the AIC values of factors were good (between 0.721 to 0.859) . All of factors had an convergent and divergent validity. Conclusion Appropriate psychometric properties and factor construct of the questionnaire were confirmed. Hence, MAPP-QOL can be used as a suitable tool in Iranian postpartum women.

The study aimed to carry on the process of the cultural adaptation of the Italian Spine Youth Quality of Life Questionnaire (ISYQOL) into Polish (ISYQOL-PL). The a priori hypothesis was: the ISYQOL-PL questionnaire is reliable and appropriate for adolescents with a spinal deformity. Fifty-six adolescents (mean age 13.8 ± 1.9) with idiopathic scoliosis (AIS) with a mean Cobb angle 29.1 (±9.7) and two with Scheuermann juvenile kyphosis (SJK) with a kyphosis angle 67.5 (±17.7) degrees were enrolled. All patients had been wearing a corrective TLSO brace for an average duration of 2.3 (±1.8) years. The Institutional Review Board approved the study. The cross-cultural adaptation of the ISYQOL-PL was performed following the guidelines set up by the International Quality of Life Assessment Project. The reliability was assessed using internal consistency (the Cronbach’s alpha coefficient) and test–retest reliability (intraclass correlation coefficient ICC2.1, CI = 95%); moreover, floor and ceiling effects were calculated. The internal consistency was satisfactory (Cronbach’s alpha coefficient 0.8). The test–retest revealed high reliability with the value of ICC2.1 for the entire group 0.90, CI (0.84 to 0.94). There was neither floor nor ceiling effect for the ISYQOL-PL overall score. The ISYQOL-PL is reliable and can be used in adolescents with spinal deformity.

Abstract Background To assess the psychometric properties, including internal consistency, construct validity, criterion validity, criterion-group validity, and responsiveness, the Reviewed McGill Quality of Life Questionnaire (MQOL-R), into Brazilian Portuguese-(BrP). Also, to analyze the relationship of the BrP-MQOL-R with the scores on the Karnofsky Performance Scale (KPS) and on the Numerical Pain Scale (NPS 0–10). Methods The BrP-MQOL-R was administered to a sample of 146 adults (men = 78). A team of experts translated the MQOL-R according to international guidelines. Convergent validity and Confirmatory factor analysis (CFA) was performed. Results The BrP-MQOL-R Cronbach’s alpha was 0.85. CFA supported the original four-factor structure, with the following revised model fit-indices: PCLOSE = 0.131, Tucker-Lewis Index (TLI) rho 2 = 0.918, incremental fit index (IFI) delta 2 = 0.936. The convergence validity is supported by a significant correlation between BrP-MQOL-R total scores and their subscales with KPS and with the single item related to the quality of life. And by a converse correlation with the pain scores in the NPS (0–10). Receiver operator characteristics (ROC) analysis showed subjects with KPS equal to or lower than 30% could be discriminated from those with scores on KPS higher than 30% by an area under the curve (AUC) = 0.71, sensitivity = 97%, and specificity = 92%). Conclusion The BrP-MQOL-R proves to be a reliable instrument for assessing the quality of life (QOL) in palliative care (PC), with primary evidence of validity. BrP-MQOL-R presented adequate discriminate properties to identify distinct conditions that impact the QOL in PC.

Introduction: Parkinson’s disease has a significant impact in quality of life, which can be assessed with 39-item Parkinson’s Disease Questionnaire and Parkinson’s Disease Quality of Life Questionnaire. This study aimed to evaluate the reliability and validity of these scales in Portuguese patients.Material and Methods: Reliability was assessed through internal consistency (Cronbach’s alpha) and reproducibility (intraclass correlation coefficient). Regarding construct validity, we performed one-way analysis of variance across different groups according to modified Hoehn and Yahr scale. For criterion validity, we compared both scales with each other and with the Short Form 36-item Health Survey.Results: In a total of 100 patients with Parkinson’s disease, Cronbach’s alpha ranged for 39-item Parkinson’s Disease Questionnaire between 0.66 - 0.98, and for Parkinson’s Disease Quality of Life Questionnaire, between 0.78 - 0.98. Intraclass correlation coefficient for 39-item Parkinson’s Disease Questionnaire ranged between 0.49 - 0.96, and for Parkinson’s Disease Quality of Life Questionnaire, ranged between 0.65 - 0.96. Both scales showed, in general, capacity to discriminate differences among patients in the different stages of disease. The scales presented moderate to strong magnitude correlations with some Short Form 36-item Health Survey domains.Discussion: Cronbach’s alpha coefficients for most domains were satisfactory. Overall, it has been demonstrated good reproducibility, as well as construct and criterion validity.Conclusion: The Portuguese versions of both scales showed to be valid and reliable.

Abstract Background Graves’ disease is the most common cause of hyperthyroidism. It results in accelerated tissue metabolism with multi-organ involvement ranging from cardiovascular to neuropsychological function. This results in a negative impact on the quality of life (QOL) of the individual patient. We aim to evaluate the psychometric properties of ThyPRO, a Thyroid-related Patient Reported Outcome questionnaire, and validate its use in our multi-ethnic Asian patients with Graves’ hyperthyroidism. Methods Forty-seven consecutive Graves’ hyperthyroidism patients answered the ThyPRO questionnaire at baseline and at 4 months after treatment initiation. Data were recorded for thyroid related symptoms and signs, thyroid function tests and thyroid volume. We analyzed the internal consistency using Cronbach’s alpha, construct validity by evaluating relationship between clinical variables and ThyPRO scales, ceiling and floor effects, and responsiveness of ThyPRO to treatment based on Cohen’s effect size. Results Correlations between individual scale scores and free thyroxine concentrations were moderate and statistically significant: 0.21–0.64 (p <  0.05). There was high internal consistency between the items in this instrument, Cronbach’s alpha > 0.7 for all scales. ThyPRO was responsive to the changes in QOL after treatment (Effect Size: 0.20–0.77) in 9 of the 14 scales including the hyperthyroid symptoms and psychosocial scales (Tiredness, Cognitive complaints, Anxiety, Emotional susceptibility, Impact on Social, Daily and Sex life). Conclusion This study provides evidence that ThyPRO has satisfactory measurement properties in hyperthyroid Graves’ disease patients in Singapore population with the potential to complement clinical care.
