Scale Validation for the identification of falsified hand sanitizer: Public and Regulatory Authorities Perspectives from United Arab Emirates

Abstract Background: Since the time of declaration of global pandemic of COVID-19 by World Health Organization (WHO), falsified hand sanitizers surfaced regularly in markets, posing possible harm to public due to unlisted inclusion of methanol. The current research is an attempt to develop and validate a tool to document falsified hand sanitizer in the UAE community.Method: A descriptive cross-sectional community-based study was conducted among 1280 randomly selected participants. Respondents were sent a web-based electronic link to the survey via email. Content validity, factor analyses and known group validity were used to develop and validate a new scale to identify falsified hand sanitizer. Test-retest reliability, internal consistency, item internal consistency (IIC), and intraclass correlation coefficients (ICCs) were used to assess the reliability of the scale. SPSS version 24 was used to conduct data analysis.Results: A total of 1280 participants were enrolled in the study. The content validity index (CVI) was 0.83 with the final scale of 12 items. The Kaiser-Meyer-Olkin (KMO) value was 0.788, with the Bartlett test of sphericity achieving statistical significance (p <0.001). Our factor analysis revealed a 3-component model. The 3-factor solution was confirmed by PCFA analysis and had associations with good fit values. The PCFA for NFI was 0.970, CFI 0.978, and TLI 0.967. All values were in excess of 0.95, with RMSEA values below 0.06 at 0.03; all of these values indicated a good model fit. The Cronbach's alpha was good overall (0.867). All factors had a Cronbach's alpha value in excess of 0.70. The instrument demonstrated that every item met the IIC correlation standard ≥ 0.40. The scale displayed good overall ICC statistics of 0.867 (95% CI 0.856 - 0.877) with statistical significance (p < 0.001). The scale's test-retest reliability was assessed through correlation of the falsified hand sanitizer identification score of respondents at the two time points. The test-retest correlation coefficient was 0.770 (p value <0.01). Participants with post-graduate education were more likely to identify the falsified hand sanitizer compared to those with high school education. (p < 0.001).Conclusions: This study developed and validated a new scale for the measurement of falsified hand sanitizer. This is expected to improve and promote collaboration between the health regulators and the public and hereby encourage customer satisfaction and participation.

Test Retest Reliability

Limitations in hand function are common among children with cerebral palsy (CP), with almost 50% presenting an arm–hand dysfunction. However, there is no standardized assessment tool available in Italian for evaluating bimanual performance for this population. Our objective in this study was to evaluate the psychometric properties of an Italian translation of the ABILHAND-Kids (ABILHAND-Kids-IT) among children with CP. We examined internal consistency using Cronbach’s Alpha and Omega coefficients, and we investigated test-retest reliability with intraclass correlation coefficients (ICC). We performed explorative factor analysis (EFA) to investigate structural validity. We calculated Pearson’s correlation coefficients between the ABILAND-Kids IT and the Manual Ability Classification System (MACS) to assess criterion validity; and, to demonstrate the score variability of the ABILHAND-Kids-IT, we used analyses of variance (ANOVAs) to compare the 181 children with CP in this sample with their levels on the MACS. We enrolled 181 children with CP in the study. EFA confirmed a uni-dimensional scale. We obtained internal consistency on both Cronbach’s Alpha and Omega coefficient of 0.98, and a one-week test-retest reliability analysis revealed an ICC with 95% of confidence interval of .992. The ANOVA revealed significant score variability ( p < 0.01) and the Pearson correlation coefficient comparing the ABILHAND-Kids-It score with the MACS was –0.929 ( p < 0.01). We conclude that the ABILHAND-Kids-IT is valid and reliable for use with Italian children with CP.

Purpose. The primary aim of this study was to translate a self-reported questionnaire (KOOS) from English to Urdu and then to see its internal consistency, agreement, test-retest reliability, and validity among primary OA knee patients. Methodology. First, KOOS questionnaire was translated from English language to Urdu through standardized cross-cultural protocol. This translated version of KOOS was administered to 111 radiographically diagnosed primary OA knee patients at two times with 48-hour interval in-between. Cronbach’s alpha, floor and ceiling effect, intraclass correlation coefficient (ICC), absolute agreement %, and Spearman correlation were used to fulfill our objectives. Results. Average time to administer this questionnaire was 20 minutes. There was good internal consistency with Cronbach’s alpha ranging from 0.7246 to 0.9139. The absolute agreement of each item between two tests ranged from 81.08% to 98.20%. Test-retest reliability was excellent (“r” ranged from 0.9673 to 0.9782). There was no ceiling effect; however less than 4% floor effect was seen in two subscales. There was significant difference that existed between different X-ray grades in all subscales meaning good content validity for disease prognosis. Conclusion. The present results show that KOOS Urdu version is a reliable and valid measure for primary OA knee patients.

External criterion was used as criterion validation (the instrument was applied to the focus group expert vs focus group team of Paediatric-HCP in hospitals). The focus group of experts who participated in psychometrics was asked to respond to the QUESA-P twice in order to assess test-retest reliability. The content validity of the initial questionnaire was assessed by the Delphi method and pilot test. Subsequently, we made minor revisions and finalized the QUESA-PResultsSelection of domains and facets were based on literature review made in duplicate by authors. Content validity was done by trial of different examiners (panellists, n=16), conducting analysis through Delphi method (three rounds). The QUESA-P was constructed with three domains. The intraclass correlations (0.80) and the Cronbach’s alpha coefficient (0.82), indicated adequate test–retest reliability and internal consistency for each domain. The application of the QUESA to 61 Paediatric-HCP in hospital resulted in lower mean score of 42.1 ± 3.4 in all domains when compared with expert teams (n= 46) 48.2 ± 3.7 (p <0.001) indicating that the instrument is valid to discriminate QUESA experts and Paediatric-HCP.ConclusionThe selected domains can be used to check weaknesses in the identification, management and reporting of suspected ADR by Paediatric-HCP in Brazil.

Abstract Background The Michigan Hand Questionnaire (MHQ) is widely used to assess the hand/wrist conditions. We translated the original version into Thai (Thai MHQ) and evaluated its psychometric properties. Methods After receiving permission, the original MHQ was translated and cross-culturally adapted to Thai following standard guidelines. Two hundred and seventeen patients who had hand/wrist injuries or disorders were included in the study. Internal consistency was evaluated using Cronbach’s alpha. Test-retest reliability was analyzed using the intraclass correlation coefficient (ICC). Spearman’s rank correlation among the subscales of Thai MHQ, Thai DASH and Thai EQ-5D-5L and also confirmatory factor analysis (CFA) were used to explore construct validity. The standardized response mean (SRM) was used to evaluate the responsiveness of the Thai MHQ. Results All subscales showed an acceptable Cronbach’s alpha (0.79–0.98). The test-retest reliability of each subscale was good (ICC = 0.83–0.95). In related dimensions, strong correlation was demonstrated between the Activities of daily living subscale of the Thai MHQ and the Common activities subscale in the Thai DASH (r = 0.77, P < 0.0001). For unrelated dimensions, a weak correlation was found between the Aesthetics subscale in the Thai MHQ and the Mobility subscale in the Thai EQ-5D-5L (r = − 0.13, P = 0.05). The Thai MHQ had strong correlation with Thai DASH (r = − 0.79, P < 0.0001) and Thai EQ-5D-5L (r = 0.63, P < 0.0001). CFA showed that the 6-factor model demonstrated an acceptable fit to the data. The SRM of the Thai MHQ was 0.78, indicating relatively large responsiveness. The MIC of Thai MHQ using distribution methods (SEM) was 5.2. Conclusions The Thai MHQ provides adequate internal consistency in all subscales as well as good construct validity and reliability for Thai patients and a relatively large standardized response mean at 2 months after treatment.

Background: The Copenhagen Burnout Inventory (CBI) is a commonly used tool for evaluation of job burnout in three (personal, work-related and client-related) domains. The aims of this study were to translate and investigate the psychometric properties of the Iranian (Persian) CBI. Methods: A total of 750 employees of different occupations (from educational centres, healthcare, industrial settings, and social services) participated in this descriptive methodological study. Aforward-backward procedure was applied and content validity was evaluated by a panel of10 experts. Exploratory and confirmatory factor analyses were used for construct validity. The internal consistency (using Cronbach’s alpha), test-retest reliability (using intraclass correlation coefficient – ICC), and feasibility (using ceiling and floor effect) were also assessed for this tool. Results: Content validity of the Persian CBI was established. Three-factor structure of the PersianCBI was supported by the factor analysis, and this confirmed the construct validity of the instrument. The internal consistency (Cronbach’s alpha ranged from 0.82 to 0.90) and test-retest reliability (ICC ranged from 0.85 to 0.95) were excellent and there was no ceiling or floor effect. Conclusion: The Persian CBI is a valid and reliable measurement tool for burnout in the Iranian context.

Test Retest Reliability

Abstract Background: Memory tests focused on binding may be more sensitive to diagnose Alzheimer´s disease (AD) at an early phase. TMA-93 examines binding by pairs of drawings of semantically-related objects. Preliminary validation studies have confirmed good diagnostic accuracy for the test to discriminate between patients with cognitive impairment and healthy controls (HCs) in low-educated populations. This study aimed to evaluate the reliability (internal consistency and test-retest reliability) of the TMA-93ina clinic setting with a high proportion of individuals with low-educational attainment. Methods.-The study was undertaken in a memory clinic of a university hospital in Southern Spain. The internal consistency of the 10 items that compose the TMA-93 was estimated on a cross-sectional, case-control study. 35 patients with amnestic Mild Cognitive Impairment and 40 healthy controls (HCs) matched by age, gender, and educational attainment were tested by the TMA-93. The participant’s performance on each of the 10 items was scored from 0 to 3, according to the instructions for the test (maximum total score= 30 points). The internal consistency was estimated by Cronbach’s alpha. In addition, “split-half reliability”, by Spearman-Brown coefficient;“corrected item-total correlations”, and item redundancy, by “Cronbach’s alpha if item deleted”, were analyzed. The test-retest reliability for the TMA-93 total score was studied in 51HCstested by the same examiner 2-4 months apart and quantified by the intraclass correlation coefficient (ICC). Results.-Internal consistency was “optimal” (Cronbach’s alpha=0.936). Split-half reliability was also high (Spearman-Brown coefficient= 0.911). The item-total score correlations were always above 0.660. No item was redundant as Cronbach’s alpha did not increase at deleting anyone. Test-retest reliability was “good” [ICC=0.802 (CI 95%=0.653-0.887)].Conclusion.-The internal consistency and test-retest reliability of the TMA-93 are “good”. In addition to other psychometric properties, these results support the test for examining memory binding,particularly in contexts of low-educational attainment.

Psychometric evaluations were performed on a self-perceived localization disabilities and handicaps questionnaire. Twenty individuals with normal hearing bilaterally, twenty with profound unilateral hearing impairment (UHI), and ten with any degree of bilateral hearing impairment participated. Each subject completed the questionnaire. Comparisons of the responses of the subjects with normal hearing and those with UHI revealed significant differences among the groups for both disabilities and handicaps, establishing construct validity. Cronbach's Alpha correlational analyses of the responses of all subjects with hearing impairment revealed correlations of .900 (disabilities) and .800 (handicaps), establishing internal consistency. Each participant with hearing impairment was asked to complete the questionnaire again after three weeks. Pearson's correlational analyses of the responses at time one versus time two revealed correlations of .900 (disabilities) and .700 (handicaps), establishing test/retest reliability. This questionnaire is an appropriate tool for investigating the self-perceived localization disabilities and handicaps of individuals with hearing impairment.
