Background/rationale: This study tested the psychometric properties of the Quality of Life in Late-Stage Dementia (QUALID) Scale using Rasch analysis. The QUALID includes 11 items with a 5-point response scale. Scores range from 11 to 55, and lower scores indicate higher quality of life (QoL). Methods: Baseline data from a randomized clinical trial including 137 residents from 14 nursing homes were used. Psychometric testing included item mapping, evaluation of response categories, item reliability, construct validity based on INFIT and OUTFIT statistics, and convergent validity based on correlations between QoL and pain, agitation, depression, and function. Results: The Cronbach α was .89. All the items except “appears physically uncomfortable” fit the model. There was a significant relationship between QoL and depressive symptoms ( r = .71, P = .001), pain ( r = .26, P = .01), physical function ( r = −.19, P = .03), and agitation ( r = .56, P = .001). The categories were appropriately used. Item mapping suggested a need for easier items.

Abstract Background: Parents of children with autism spectrum disorder (ASD) are known to poorer quality of life. The Quality of Life in Autism Questionnaire (QoLA) is a commonly used instrument for measuring the quality of life in parents of children with ASD. The aim of this study was to evaluate the reliability and validity of the QoLA in Iranian mothers of children with ASD.Methods: The sample of this methodological study consisted of 88 mothers of children with ASD in Arak, Iran. The data were collected using convenience sampling method between September 2019 and January 2020. A battery of questionnaires was administered to mothers which included the QoLA, Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Perceived Stress Scale-4 (PSS-4). Factor structure and internal consistency of the QoLA were examined via confirmatory factor analysis (CFA) and Cronbach’s alpha, respectively. Convergent validity was examined by relationship with WHOQOL-BREF, PHQ-9, GAD-7 and PSS-4.Results: The mean total scores of QoLA Part A and Part B were 86.50 (SD=13.89) and 61.41 (SD=18.21), respectively. Both subscales exhibited good internal validity (with Cronbach’s alpha of 0.899 and 0.950 for Part A and Part B, respectively). The convergent validity of both subscales of QoLA was proved via moderate to strong correlations with measure of the WHOQOL-BREF. In addition, both QoLA Part A and Part B scores were negatively correlated with measures of PHQ-9, GAD-7, and PSS-4. The confirmatory factor analyses provided evidence for unidimensionality of both subscales of QoLA.Conclusion: The Persian version of QoLA displays satisfactory reliability and validity in Iranian mothers of children with ASD.

The aim of this study was to investigate the reliability and validity of the Norwegian Kidscreen-27 questionnaire, a measure of generic health-related quality of life, in 10 year-old children. The Kidscreen-27 consists of five domains and was validated in a sample of 56 school children (29 boys). The children completed the questionnaire at three different time points during two consecutive school days. For convergent validity, the study was powered to detect a statistically significant correlation coefficient of 0.4. Cronbach's alpha values ranged from 0.73 to 0.83. Floor effects were all zero and ceiling effects ranged from 1.7% to 23.7%. Intraclass correlation values over time ranged from 0.71 to 0.81. However, some individual variability over time occurred and was illustrated by Bland Altman plots. The domains of physical well-being, psychological well-being and autonomy & parents improved over time (Ps < 0.05), while social support and school environment domains did not. We assessed convergent validity using general life satisfaction scores obtained by administering the Cantrils Ladder. All the Kidscreen-27 domains were significantly associated with general life satisfaction (Spearman rank correlations ranged from 0.29 to 0.59, Ps < 0.05). In conclusion, the Norwegian version of Kidscreen-27 has good reliability and validity.

Abstract Background In order to predict social, mental and health care needs we must measure Quality of life of residents. In Afghanistan there was no assessment to measure quality of life of people. The aim of this study was to culturally adapt the WHOQOL-BREF into Dari language of Afghanistan and present its psychometric properties. Methods Cultural adaptation of the WHOQOL-BREF into Dari has consisted of two stages: translation stage, and the cognitive debriefing (pilot) stage following the translation stage. The process of translation of WHOQOL-BREF included recommended methodology, mandating forward translation, backward translation was followed. A total number of 1473 people did participate in this research. Psychometric analyses consisted of item analyses; reliability and validity analyses. Internal consistency analyses were done by Cronbach's alpha value and validity analyses consisted of construct validity (convergent validity by SF-36 and confirmatory factor analyses) and criterion validity (multiple linear regression by overall QoL item (item1)) analyses. Acceptable type 1 error was considered as 0.05 in all analyses. Analyses were done by using Lisrel v8.05 statistical package. Results Item domain correlations and -if item deleted- Cronbach alpha values no problematic item in Afghan version of the WHOQOL-BREF. Internal consistency of the scale was in acceptable limits for all domains (alpha values = 0.79–0.80) except for the social relations domain (alpha = 0.41). Using overall QoL item (item q1) as the dependent variable, multiple regression analysis revealed a R2 value of 57% and all of the four domains of the WHOQOL except that of Social relation domain (beta = 0.03) could explain the variance of the q1, the best domain is the environmental domain with a beta value of 0.30. Construct validity is tested by known groups validity; factorial validity and the convergent validity. All of the known categories of the age, gender, education, social class and economic status, having chronic illness were significantly sensitive to the domain scores of the WHOQOL (p < 0.001). Physical and Psychological domains of the WHOQOL-BREF was highly correlated with the related domains of the SF-36 (r = 0.60 and 0.64). Social and environmental domains showed poor correlations with the SF36. Confirmatory factor analyses showed acceptable goodness of fit results. Chi-square = 2174,748 and Degrees of freedom = 246; GFI: 0.88, CFI: 0.83; RMR: 0.066 and RMSEA: 0.073. Conclusion Afghan Dari version of the WHOQOL-BREF can confidently be used in clinical setting and in population level to assess the QoL of the people. The results of the social relations domain should be interpreted with caution due to its poor psychometric power. Further studies are needed to address the social aspects of quality of life in Afghan population.

Summary: The aim of this study was to validate the use of short, generic, quality-of-life (QoL) questionnaires in a population of myocardial infarction survivors. The feasibility, reliability, and validity of two short questionnaires (the MOS-24 and the COOP/WONCA charts) were evaluated and compared with a long questionnaire (the Sickness Impact Profile). The study population consisted of 99 myocardial infarction survivors some years after the event and 101 referents without a history of heart or brain infarction. The feasibility of the short questionnaires was good. Both instruments covered the most important domains of QoL, similar to the Sickness Impact Profile. In addition, the two short questionnaires measured “pain” and the MOS-24 also covered “vitality.” The MOS-24 had a smaller floor effect than the COOP/WONCA charts. The MOS-24 was shown to be a reliable test. Both short instruments were able to detect between-group differences (especially MOS-24) although at different rates. Convergent validity of the MOS-24 was high compared with the COOP/WONCA charts. In contrast, the discriminant validity of the COOP/WONCA charts was better. The discriminant validity of the MOS-24 was, nevertheless, reasonable. In conclusion, both instruments are suitable for measuring the QoL of myocardial infarction survivors. The multi-item MOS-24 questionnaire however, is slightly preferable.

Abstract Background In addition to increasing linear growth, improvement in health-related quality of life (HRQOL) is an important endpoint in the treatment of short statured youth. Hence, condition-specific psychometric valid instruments that adequately assess HRQOL are needed. We aimed to confirmatorily examine the psychometric performance of the Quality of Life in Short Stature Youth (QoLISSY) questionnaire used in a previously reported prospective randomized open-label trial. Methods This trial compared treatment of idiopathic short stature (ISS) in 76 adolescent males with either oral aromatase inhibitors (AIs), subcutaneous daily growth hormone (GH) or a combination treatment (AI/GH) for at least 2 years, demonstrating improvements in HRQOL with the GH and AI/GH interventions. HRQOL was assessed from the child’s and parent’s perspectives with the short stature-specific QoLISSY and the generic KIDSCREEN questionnaires before and 24 months into treatment. Scale scores and psychometric properties were examined regarding reliability and validity of the QoLISSY questionnaire using the dataset from the published trial. Results The QoLISSY questionnaire showed high internal consistency and satisfactory criterion, convergent and known-groups validity. Scale scores were evenly distributed with no major floor or ceiling effects. Responsiveness analyses suggest that the QoLISSY questionnaire detects significant changes in HRQOL after 2 years of treatment with growth-promoting therapies in children with short stature from both the child’s and parent’s perspectives. Conclusions The QoLISSY questionnaire is a psychometrically sound, reliable and valid instrument that can explore the experiences associated with short stature, track HRQOL changes over time and in response to treatment, and highlight HRQOL domains that can be improved through intervention.

Background The aim of this methodological study was to assess the reliability and validity of the Sexual Quality of Life – Male (SQoL-M) questionnaire translated and adapted to measure the sexual quality of life of men in Turkey and Northern Cyprus. Methods: To assess the reliability and validity of the Turkish version of the SQoL-M questionnaire, in January and February 2017 we formed a sample of 128 men from Ankara, Turkey, and Girne, Northern Cyprus, to complete the questionnaire. Two weeks later, 65 of these men completed the questionnaire during a retest. Factor analysis was conducted to evaluate the questionnaire’s factor structure, internal consistency and test–retest reliability analyses were used to assess reliability and Pearson’s correlation coefficient was used to measure criterion-related validity. Results: Cronbach’s α for the Turkish version of the SQoL-M questionnaire was 0.91, with corrected item–total score correlations ranging from 0.432 to 0.819. The test–retest correlation, calculated to compare scale scores of both groups of participants, was 0.83 (P<0.001). We also observed a statistically significant relationship between the Turkish version of the SQoL-M questionnaire and the Arizona Sexual Experience scale. Conclusions: The Turkish version of the SQoL-M questionnaire is a valid, reliable instrument for evaluating the sexual quality of life of men in Turkey and Northern Cyprus.
