Background: There is an agreement that the methodological quality of randomized trials should be assessed in systematic reviews, but there is a debate on how this should be done. We conducted a construct validation study of the Physiotherapy Evidence Database (PEDro) scale, which is widely used to assess the quality of trials in physical therapy…

This study presents the reliability and validity of the Teacher Evaluation Experience Scale--Teacher Form (TEES-T), a multidimensional measure of educators' attitudes and beliefs about teacher evaluation. Confirmatory factor analyses of data from 583 teachers were conducted on the TEES-T hypothesized five-factor model, as well as on alternative…

Almond, Yoon Jeon Kim, Gertrudes Velasquez, and Valerie J. Shute. Here, Walker and Englehard write…

This article examines the Consortium on Reading Excellence-Phonics Survey (CORE-PS), an informal, inexpensive, and widely disseminated assessment tool that is used to determine primary-grade students' knowledge of and abilities to apply key alphabetic and phonics understandings to decode a mix of real and pseudo-words. Evidence is reported of the…

The principal aim of the study is to develop a new scale Science Anxiety Scale and to examine its the psychometric properties and construct validity of the Science Anxiety Scale in a sample of 797 primary school students. Exploratory factor analysis was applied and found to have a two-dimensional structure. Confirmatory factor analyses provide…

Anxiety may exacerbate interpersonal difficulties and contribute to secondary behavioral problems in adolescents with High-Functioning Autism Spectrum Disorder (HFASD). This study was conducted to assess the psychometric properties and construct validity of measures of anxiety with a sample (n = 30) of adolescents with HFASD and comorbid anxiety…

Despite the current need for reliable and valid test instruments in different countries in order to monitor the sign language acquisition of deaf children, very few tests are commercially available that offer strong evidence for their psychometric properties. This mirrors the current state of affairs for many sign languages, where very little…

The purpose of this study was to develop an instrument to assess college students' efficacy beliefs for conceptual change and to examine the psychometric properties of the instrument. Participants were 692 students. Results of the confirmatory factor analysis supported the hypothesized single factor structure of Efficacy Beliefs for Conceptual…

Recent handbooks of giftedness or expertise propose a plethora of conceptions on the development of excellent performance but, to our knowledge, there are no comparative studies that provide empirical evidence of their validity to guide researchers and practitioners in their adoption of a particular conception. This study sought to close that gap…

Many personnel committees at colleges and universities in the USA use student evaluation of faculty instruction to make decisions regarding tenure, promotion, merit pay or faculty professional development. This study examines the construct validity and internal consistency reliability of the student evaluation of instruction (SEI) used at a large…

The purpose of this study was to explore college students' recognition of temporal magnitudes associated with durations of scientific changes through construct validation of a 30-item instrument. We administered the instrument to 514 students from 10 higher education institutions in the United States. Among them, 419 students took the instrument…

Organizational citizenship behavior (OCB) has been associated with organizational effectiveness in many studies. Therefore, it is important to learn more about how these behaviors can be improved in schools. Creating a reliable and valid measure of OCB that has conceptual equivalence across cultures is a first step in understanding and…

This study examined the construct validity of the Career Locus of Control Scale (CLCS) among diverse urban youth within the United States (N = 308). Confirmatory factor analyses verified two of the three models as acceptable fits. Two new models were also explored. Model 5 (Internality, Luck, and Non-Control), which was one of the new models, was…

Extended time is one of the most common testing accommodations provided to students with disabilities. It is also controversial; critics of extended time accommodations argue that extended time is used too readily, without concern for how it changes the skills measured by tests, leading to scores that cannot be compared fairly with those of other…

The purpose of the study was to examine the psychometric properties of the "Preschool Language Scale-4" (PLS-4) with a sample of English-speaking Hispanic and European American children who attended Head Start programs. Participants were 440 children between the ages of 3 and 5 years (52% male; 86% Hispanic and 14% European American).…
