Statement of the purpose: The aim of this study was to develop a valid and reliable satisfaction tool that can be utilised in the emergency departments (EDs) of hospitals throughout Sharjah, United Arab Emirates (UAE). Methods: The study followed a cross-sectional study design. The study was conducted during the period from October 2018 to January 2019. The participants were conveniently sampled. The total number of eligible questionnaires for analysis accounted for 207. The data collection tool was developed following a review of literature which yielded 25 statements. Satisfaction levels were measured using a 3-point Likert scale (satisfied=3, do not know=2, dissatisfied=1). The tool was validated through face validity performed by the research team. Content validity performed by a panel of nine randomly selected specialists. Principal components analysis was done to extract the relevant components to the statements on the tool. Results: Scale content validity index= 0.836. Principal components analysis with oblique rotation extracted three components namely; medical staff performance, duration of the encounter, and general impression about the emergency department. Internal consistency for the tool using the split-half Cronbach’s alpha, part 1=0.80, and part 2=0.82. Conclusion: The findings of the present study support the reliability and validity of the Emergency Services Patient Satisfaction Questionnaire for intended use, following an independent sample of patients at EDs in Sharjah, UAE. The scale is recommended for assessing patient satisfaction with service provision to help hospitals in Sharjah determine to what extent they are meeting the needs of their patients.

The purpose of this study was to assess validity and reliability of the Physical Educators’ Attitude Toward Teaching Individuals with Disabilities III (PEATID III; Rizzo, 1993) for future professionals. Participants (N = 3,464) were undergraduate students enrolled in the introductory adapted physical education course at 235 colleges and universities. Construct validity was obtained through principal components analysis with oblique rotation and supported by principal components analysis with varimax rotation. Results showed that PEATID III measures three factors: (a) outcomes of teaching students with disabilities in regular classes, (b) effects on student learning, and (c) need for more academic preparation to teach students with disabilities. Reliability, as estimated through coefficient alpha, was .88 for the total scale and .71 or greater for each of the disability subscales.

Components Analysis

Using a sample of 104 employed business students attending evening courses at a state university, the dimensionality of a pay satisfaction questionnaire was examined. A principal components analysis with an oblique rotation was used to assess whether items hypothesized to load on a raise in pay component and a structure/administration component would actually load on those respective components. This analysis was also compared to one with an orthogonal rotation to assess the assumption of orthogonality between the hypothesized dimensions. The raise and structure/administration items all loaded on a single component along with pay level items, and, based upon hyperplane counts, the assumption of orthogonality between dimensions of satisfaction with pay is poor.

Time Point

Few studies have examined the longitudinal nature of dietary patterns obtained using principal components analysis (PCA); the methods used are inconsistent. This paper investigates the methodologies used to assess stability and changes in such patterns. Pregnant women recorded frequency of consumption of various food items as part of regular self-completed questionnaires in the Avon Longitudinal Study of Parents and Children. This was repeated when their children were 4 years of age; 8953 women provided data at both times. Dietary patterns were identified using PCA and component scores were calculated at each time point. Additional ‘applied’ scores were created at 4 years using the loadings obtained from the PCA on the pregnancy data. Correlations were similar for each component across the time points, though slightly larger using the applied method. The applied scores were considerably lower on average than those obtained from separate PCA at 4 years. Women's scores decreased on ‘health conscious’ and ‘confectionery’ components while ‘processed’ and ‘vegetarian’ scores both increased over the 4-year period. In contrast, applied scores were systematically lower for all components. When split into quintiles, weighted κ was slightly higher between pregnancy and applied 4-year scores compared to the separate scores. In this cohort it was felt that the ‘applied’ method to obtain scores at the second time point was inappropriate, primarily due to the differences in FFQ between the two time points. We recommend that future studies using such ‘applied’ scores compare them with cross-sectional scores and consider the implications of any differences.

Data taken from the blood of 262 patients diagnosed for malabsorption, elective cholecystectomy, acute cholecystitis, infectious hepatitis, liver cirrhosis, or chronic renal disease were analyzed with three numerical taxonomy (NT) methods : cluster analysis, principal components analysis, and discriminant function analysis. Principal components analysis revealed discrete clusters of patients suffering from chronic renal disease, liver cirrhosis, and infectious hepatitis, which could be displayed by NT clustering as well as by plotting, but other disease groups were poorly defined. Sharper resolution of the same disease groups was attained by discriminant function analysis.
