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.

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.

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.

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.
