This study aims to determine the reliability of the Beck Depression Inventory (BDI), a widely used tool for diagnosing depression--a condition that significantly impacts individuals' lives--through meta-analysis, an advanced statistical technique. To achieve this objective, studies conducted in Turkey between 1961 and 2021 that utilized the Beck…

The acceptance of artificial intelligence (AI) in academic settings, particularly in the context of research creativity, is a growing area of interest. This study aimed to design and validate the AI Acceptance and Research Creativity Scale (AIA&RCS) among faculty members. This exploratory mixed-method was conducted among 720 faculty members. A…

Research courses are part of many higher education curricula. However, students' attitudes towards statistics and research courses tend to be negative. One way to measure students' attitude is with the Revised-Attitudes Towards Research scale (R-ATR). The current study examined: (1) the internal reliability of the R-ATR, (2) the attitude of Dutch…

This study is part of a research about the use of ICT resources by Higher Education teachers to teach, evaluate and research (UICT-TER). The aim, in this case, is the creation and validation of a measuring instrument on the use of ICT resources based on the UICT-TER model. After the preparation and application of the instrument to a sample of 867…

There is a growing interest in the perceived research environment for higher education academics. As there is no existing, psychometrically sound scale that directly measures perceived research environment for higher education academics, we designed and validated the Perceived Research Environment Scale for use with this population. In Phase 1,…

This study serves to develop a multidimensional scale for assessing the digital fluency of preadolescents. The researchers applied exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to evaluate the constancy of the classified factors and to elucidate relationships among factors in the Digital Fluency Scale. A total of 224…

Six commonly used instruments for assessment of eating disorders were analyzed. Effect size results from Erford et al.'s (2013) meta-analysis for the treatment of bulimia nervosa were used to compare each scale's ability to measure treatment outcomes for bulimia nervosa. Effect size comparisons indicated higher overall effect sizes using the…

This study describes the development of an assessment to evaluate the well-being of PhD researchers using a clinically approved methodology that places the perceptions and experiences of the subject population at the heart of its construction. It identifies and assesses the range and relative importance of seven distinct dimensions which are shown…

Based on dissertation for EdD degree at University of Texas (1966).

The stepped-up reliability coefficient does not have the same standard error as an ordinary correlation coefficient. Fisher's Z -transformation should not be applied to it. Appropriate procedures are suggested. (Author)

Given multiple independent measures of an underlying true factor and information on group membership, it is possible to compute a set of observed group means for each measure. Given at least three tests, these sets of means may be used to compute the reliability of the means for each test. The procedure for estimating true scores from the…

A chronology of the development of a mathematics anxiety scale is given. Included are a model describing six facets of mathematics anxiety and the eighteen items used on the anxiety scale. Stability and internal consistency measures are reported, and the scale is correlated with measures of mathematical confidence and general anxiety towards…

It was hypothesized that one could predict the reliability of the shortened WAIS on the basis of the Spearman Brown formula, and that in testing, as in other fields, you get what you pay for. Results confirmed these hypotheses; a short form is not an adequate substitute for the full WAIS. (Author)

Purpose: The purpose of this report is to evaluate the reliability and validity of the five-item Evaluation to Sign Consent (ESC), a measure that can guide determination of an older adult's capacity to consent for research. Design and Methods: Information was obtained from 346 nursing home residents from six facilities who were being enrolled into…
