This study aimed to verify the construct validity and reliability of a scale of assessment quality of learning in Saudi universities, a study on a sample of Tabuk University students. To achieve this goal, the descriptive and analytical approach was used where a questionnaire was developed consisting of (32) statements distributed in five axes: content, technology and support, user interface, evaluation tools and methods, and safety. The questionnaire was applied electronically to a random stratified sample of (275) students, and was classified according to specialization and gender. The students’ responses were used to answer the study questions related to examining the scaling properties, analyzing the descriptive statistics of assessment practices and comparing the mean values according to nominal variables by using descriptive statistics, confirmatory factor analysis and two- way ANOVA. The study provided indices of the reliability and validity of the scale. The results indicated that the quality of e- learning was average according to Likert's five- point grading used in the scale, as most of the averages for expressions were statistically higher than the hypothetical mean of grading, and there were no statistically significant differences in the arithmetic averages of the sample estimates due to specialization and gender. Some recommendations were given at the end of the study, such as: using the proposed scale in diagnosing the reality of e- learning in Saudi universities, in order to improve and develop this type of learning, which we need, especially in light of the Corona pandemic.

The Protector and Scoring System was introduced in taekwondo to encourage transparency in scoring during competition. The system, which has been used in the past two Olympics, consists of two main components, the electronic body protector and socks. The few studies that have been conducted on the Protector and Scoring System have not been comprehensive and used questionable testing methods. The main objectives of this study were to methodologically examine the validity and reliability of a Protector and Scoring System body protector. To fulfil these objectives, a customized mechanical pendulum was built to test the Protector and Scoring System. The reliability of the pendulum was first determined by tracking the pendulum’s mean velocity at impact for 50 trials on two separate occasions. Data from both days were compared and showed no significant differences ( p = 0.08). Mean kinetic energy of the pendulum was then calculated to be 55.52 J. For the experimental trial, the electronic body protector was divided into 12 sections. Each section was tested with the pendulum for 50 trials on two separate days. It was found that only three sections had no significant differences between the two days ( p > 0.01), while the rest of the sections had significantly different readings between Day 1 and Day 2. Based on the homologous descriptive statistics, only two sections were in the same group, which translated to the Protector and Scoring System being only 16.7% reliable overall for both days. In terms of validity, an independent samples t-test was used to determine the differences between the calculated kinetic energy from the pendulum (the criterion) and the displayed kinetic energy on the Protector and Scoring System, and values were found to be significantly different ( p < 0.01). Overall, the reliability and validity of the Protector and Scoring System was found to be questionable. The system needs to be examined exhaustively before being used in any future tournaments.

Stigma Of Mental Illness

Purpose: This study aims to translate and test the reliability and validity of the Internalized Stigma of Mental Illness-Cantonese (ISMI-C). Methods: The original English version of ISMI is translated into the ISMI-C by going through forward and backward translation procedure. A cross-sectional research design is adopted that involved 295 participants randomly drawn from a population of Chinese consumers participated in different kinds of community-based mental health services. Results: Results show that the Cronbach’s α coefficient of the ISMI-C is .93. With regard to validity test, the ISMI-C shows significant and negative correlation with measures on self-esteem and quality of life. Also, an explorative factor analysis yields five factors that are consistent with previous research results. Discussion: This study shows that the ISMI-C is a reliable and valid measure. ISMI-C can facilitate the development of interventions in reducing self-stigma for people with mental illness across Chinese societies.

Reliability and validity have a well-established place in the development and implementation of educational assessment devices. With the advent of electronic delivery and assessment some of the factors that influence reliability and validity have changed. In order to understand the process involved the authors have suggested that a socio-technical approach to these educational issues gives an economical explanatory system. Within this socio-technical system, the authors show that the way the students extract information from sources is changing to an extent where it is difficult to distinguish between cheating and poor quoting behavior. This has led them to postulate a new classification within validity and reliability – knowledge validity and reliability. They argue that electronic delivery and assessment have not changed their core structures, but rather require revised education and training for both staff and students.

Scales were developed to measure the tendencies to blame AIDS victims or the society in which victims live. Data from a sample of 874 students were used to examine the construct validity and reliability of the scales. The list-wise deletion reduced the sample size to the usable sample size of 824. The data showed satisfactory validity and reliability of the scales so they may be used to study attitudes toward those who are suffering from AIDS and related problems.

Objective: To test the Brazilian Portuguese velopharyngeal insufficiency (VPI) Effects on Life Outcome (VELO) instrument for reliability and validity. Design: Cross-sectional methodological study. Setting: Tertiary craniofacial medical center. Participants: Participants with VPI (VPI group, n = 60), with cleft and without VPI (no VPI/cleft group, n = 60), and with no cleft nor VPI (no VPI/no cleft group, n = 60) and their parents (n = 180). Interventions: All patients with VPI 8+ years old and their parents completed the Brazilian–Portuguese VELO instrument and other questionnaires (Pediatric Quality of Life Inventory4.0, PedsQL4.0; Pediatric Voice-Related Quality of Life, PVRQOL; and Intelligibility in Context Scale, ICS) at baseline; patients with VPI and their parents completed the VELO instrument again 2 weeks later. Main Outcome Measures: The VELO instrument was tested for internal consistency, test–retest reliability, discriminant validity (participants with VPI against participants with no VPI), concurrent validity against other questionnaires, criterion validity against hypernasality severity, and construct validity against nasal air emission and overall velopharyngeal competence (speech construct) and velopharyngeal gap (anatomic construct). Results: The VELO had excellent internal consistency (Cronbach α 0.99 for parents and 0.98 for participants with VPI) and test–retest reliability (all intraclass correlation coefficient > 0.87). The VELO discriminated well between VPI group and unaffected groups (all P < .05). The VELO was significantly correlated with the PedsQL4.0, PVRQOL, and ICS (– r > 0.75; P < .001). The VELO met criterion validity, speech construct validity, and anatomic construct validity ( r > 0.7; P < .001). Conclusions: The Brazilian-Portuguese VELO instrument demonstrated reliability (internal consistency and test–retest) and validity (discriminant, concurrent, criterion, and construct).

The purpose of this study was to validate the construct and reliability of an instrument to assess the work environment as a single tool based on quality of life (QL), quality of work life (QWL), and organizational climate (OC). The methodology tested the construct validity through Exploratory Factor Analysis (EFA) and reliability through Cronbach’s alpha. The EFA returned a Kaiser–Meyer–Olkin (KMO) value of 0.917; which demonstrated that the data were adequate for the factor analysis; and a significant Bartlett’s test of sphericity (χ² = 7465.349; Df = 1225; p ≤ 0.000). After the EFA; the varimax rotation method was employed for a factor through commonality analysis; reducing the 14 initial factors to 10. Only question 30 presented commonality lower than 0.5; and the other questions returned values higher than 0.5 in the commonality analysis. Regarding the reliability of the instrument; all of the questions presented reliability as the values varied between 0.953 and 0.956. Thus; the instrument demonstrated construct validity and reliability

Background and Purpose: There are limited reliable and valid measures of the patient– provider interaction among adults with hypertension. Therefore, the purpose of this report is to describe the construct validity and reliability of the Questionnaire on the Quality of Physician–Patient Interaction (QQPPI), in community-dwelling adults with hypertension. Methods: A convenience sample of 109 participants with hypertension was recruited and administered the QQPPI at baseline and 8 weeks later. Results: The exploratory factor analysis established a 12-item, 2-factor structure for the QQPPI was valid in this sample. The modified QQPPI proved to have sufficient internal consistency and test– retest reliability. Conclusions: The modified QQPPI is a valid and reliable measure of the provider–patient interaction, a construct posited to impact self-management, in adults with hypertension.
