A comparison of Rasch item-fit and Cronbach's alpha item reduction analysis for the development of a Quality of Life scale for children and adolescents

Background:Gilles de la Tourette syndrome (GTS) is a chronic childhood-onset neuropsychiatric disorder with a significant impact on patients’ health-related quality of life (HR-QOL). Cavanna et al. (Neurology 2008; 71: 1410–1416) developed and validated the first disease-specific HR-QOL assessment tool for adults with GTS (Gilles de la Tourette Syndrome-Quality of Life Scale, GTS-QOL). This paper presents the translation, adaptation and validation of the GTS-QOL for young Italian patients with GTS.Methods:A three-stage process involving 75 patients with GTS recruited through three Departments of Child and Adolescent Neuropsychiatry in Italy led to the development of a 27-item instrument (Gilles de la Tourette Syndrome-Quality of Life Scale in children and adolescents, C&A-GTS-QOL) for the assessment of HR-QOL through a clinician-rated interview for 6–12 year-olds and a self-report questionnaire for 13–18 year-olds.Results:The C&A-GTS-QOL demonstrated satisfactory scaling assumptions and acceptability. Internal consistency reliability was high (Cronbach’s alpha > 0.7) and validity was supported by interscale correlations (range 0.4–0.7), principal-component factor analysis and correlations with other rating scales and clinical variables.Conclusions:The present version of the C&A-GTS-QOL is the first disease-specific HR-QOL tool for Italian young patients with GTS, satisfying criteria for acceptability, reliability and validity.

The Impact

Abstract Introduction As a result of high transmission and mortality rates, the Covid-19 pandemic has led to a worldwide health crisis, isolation, and widespread fear, therefore negatively influencing people’s quality of life (QOL). The goal of the present study was to examine the psychometric properties (validity and reliability) of the Persian version of the COVID-19-Impact on Quality of Life (COV19-QoL) scale. Methods After translating the scale using the forward–backward method, face and content validly was qualitatively assessed. Then the scale was distributed to 488 individuals from the general population via online platforms. Construct validity was assessed using exploratory (EFA) and confirmatory (CFA) factor analysis. In addition, internal consistency was examined using Cronbach’s alpha coefficient and McDonald’s omega, relative stability was assessed using interclass correlation coefficient (ICC), and absolute stability was calculated through examination of standard error of measurement. Results The EFA revealed one factor that explained 55.96% of the total variance of the scale. Internal consistencies of 0.823 and 0.882 were found using Cronbach’s alpha coefficient and McDonald’s omega, respectively. In addition, an ICC of 0.837 (with a two-week interval) was found. Covid-19 had a greater impact on the QOL of healthy participants than that of those with underling conditions (p = 0.004), and also on the QOL of single participants than that of married ones (p = 0.032). Conclusion The Persian version of the COV19-QoL is a valid and reliable instrument that can be used to examine the impact of Covid-19 on QOL.

Objectives To study the level of mental health literacy and quality of life among patients with stroke and to investigate the relationship between mental health literacy and quality of life. Methods A cross-sectional descriptive study was conducted with 150 purposively selected stroke patients at Sanpasithiprasong Hospital, Ubon Ratchathani, Thailand. Data were collected from October 2019 to March 2020. The research tool consisted of 3 parts: general and clinical data, a mental health literacy questionnaire, and the Thai version of the stroke-specific quality of life scale. Data were analyzed using descriptive statistics and Spearman’s rank correlation coefficient. Results The mean age of participants was 51.80 years (SD 8.62); most were female (65.33%). The level of mental health literacy among patients with stroke was moderate (mean = 3.05, SD = 0.21). The quality of life among patients with stroke was moderate (mean = 3.06, SD = 0.66). The mental health literacy questionnaire yielded a Cronbach’s alpha coefficient of 0.92, and the Thai version of the stroke-specific quality of life scale yielded a Cronbach’s alpha coefficient of 0.96. Mental health literacy was statistically significantly associated with quality of life among patients with stroke (r = 0.484, p < .001). Conclusions The mental health literacy among patients with stroke was moderate as was their quality of life. Mental health literacy was significantly associated with quality of life among patients with stroke. This suggests that emphasizing and promoting mental health literacy among patients with stroke can improve and increase their quality of life.

Quality Of Life Scale

Abstract Background Osteoarthritis (OA) is a debilitating multifactorial degenerative rheumatic disease affecting millions of people around the globe. The osteoarthritis quality of life scale (OAQoL), originally produced in the English language, is an important tool used to assess the overall impact of OA and its treatment on the patient’s quality of life. Purpose The purpose of the study was to translate and validate the OAQoL in the Arabic language in order to use it on the Saudi population. Methodology A bilingual panel comprising four healthcare professionals and one external certified medical translator translated the English version of the OAQoL to the Arabic language. A back translation was subsequently performed by two English-speaking translators and any differences were resolved by conferring with the original panel. The qualitative research was performed through cognitive debriefing interviews (CDIs) with 59 native Arabic patients who had clinically and radiologically confirmed osteoarthritis of any joint. The internal consistency of the 22 items was derived by leveraging the Cronbach’s Alpha coefficient. Results 59 participants were included in the study, and more than half (52.5%) of them were men. The response rate was 100% and the mean time taken to answer the questionnaire was 10.5 min. The average Intraclass Correlation Coefficient (ICC) and Cronbach’s Alpha were determined to be 0.93 each, indicating that all the items in the OAQoL were significantly interrelated. Conclusion The translated Arabic version of the OAQoL questionnaire used in this study is a reliable and consistent tool that showed good comprehensibility and internal consistency.
