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…

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…

There is a clear call in group counseling practice and training for evidence-based practice (ACA, 2005; ASGW, 2008; CACREP, 2009). At the same time, group counselors also are asked to keep clients' experience at the center of their work (ASGW, 2012). This article outlines the authors' effort to develop and study an instrument designed to measure…

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…

In this article, we highlight the need for a precisely defined construct in score-based validation and discuss the contribution of cognitive theories to accurately and comprehensively defining the construct. We propose a framework for integrating cognitively based theoretical and empirical evidence to specify and evaluate the construct. We apply…

This article illustrates how test specifications based solely on academic content standards, without attention to other cognitive skills and item response demands, can fall short of their targeted constructs. First, the authors inductively describe the science achievement construct represented by a statewide sixth-grade science proficiency test.…

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…
