Parallel analysis has been considered one of the most accurate methods for determining the number of factors in factor analysis. One major advantage of parallel analysis over traditional factor retention methods (e.g., Kaiser's rule) is that it addresses the sampling variability of eigenvalues obtained from the identity matrix, representing the…

Despite a call for evidence-based practice in school psychology, limited research on the topic of evidence-based assessment exists. To begin to address this gap in the research, a modified version of Jenson-Doss and Hawley's (2010) Attitudes Toward Standardized Assessment (ASA) scale was administered to 371 U.S. school psychologists. Examination…

Drawing upon a wider piece of research, this paper focuses on the validation of a 'use of assessment' scale in five Portuguese public universities with 5549 students. The study aims to investigate the psychometric properties of the scale, to describe how students look at assessment uses, to analyse their utility perceptions of assessment, and to…

Middle level school teachers commonly measure and monitor students' academic performance, but such is not the case for students' classroom behavior. This is unfortunate, given the rise in students' classroom behavior problems in middle school, especially for students who experience emotional or behavioral disorders. The Classroom Performance…

Evaluation of child-friendly school (CFS) policies is essential to determine the achievements of school efforts in reducing violence cases. This research aims to proving the reliability and validity of CFS policy evaluation instruments in elementary schools with different locations. This investigation uses the Context Input Process Product (CIPP)…

This study aimed to develop a comprehensive tool to assess underachievement in gifted students, incorporating input from parents, teachers, and students themselves. A total of 285 participants, including 95 gifted students, their parents, and teachers, were involved in the study. The results have revealed a four-factor structure for the Gifted…

Employers agree that high school graduates lack teamwork skills needed for workplace productivity. The lag in student readiness to meet employer expectations urges school reforms that implicate group interaction, empirical assessment, and reporting of teamwork competencies. The "Teamwork Skills Inventory" (TSI) evaluated how well…

This study aims to develop a scale to measure the design thinking process and to evaluate the reliability and validity of this scale. It fills this gap by introducing a 36-item scale specifically designed to measure design thinking abilities across the five key stages of the design thinking process: empathize, define, ideate, prototype, and test,…

Structural equation models comprise a large class of popular statistical models, including factor analysis models, certain mixed models, and extensions thereof. Model estimation is complicated by the fact that we typically have multiple interdependent response variables and multiple latent variables (which may also be called random effects or…

Assessing the measurement model (MM) of self-report scales is crucial to obtain valid measurements of individuals' latent psychological constructs. This entails evaluating the number of measured constructs and determining which construct is measured by which item. Exploratory factor analysis (EFA) is the most-used method to evaluate these…

The purpose of this study was to develop a multidimensional College Mental Health Assessment Inventory (CMHAI) specifically for the college student population. In the first phase, a conceptual and theoretical review of general existing scales was performed, followed by conducting exploratory semi-structured interviews with twelve participants.…

This paper reports an investigation into the psychometric properties of the COR-Advantage1.5 (COR-Adv1.5) assessment tool, a criterion-referenced observation-based instrument designed to assess the developmental abilities of children from birth through kindergarten. Using data from 8534 children participating in a state-funded preschool program…

School climate research has traditionally been carried out by separating its two main components, prosocial and antisocial behaviors. This is often a partial view of the school climate. Hence, the goal of this study is to develop an evaluation instrument (CONVIVE) that takes into account both perspectives of the school climate through a…

The study was designed as a linked two-phase investigation, aiming to psychometrically develop and validate a Chinese version of the "Organizational Climate Diagnostic Instrument for Junior High Schools" (OCDI-JH) for use in Taiwan. Through extensive literature reviews, the complex phenomena of school climate were decomposed into a…

The measurement error in principal components extracted from a set of fallible measures is discussed and evaluated. It is shown that as long as one or more measures in a given set of observed variables contains error of measurement, so also does any principal component obtained from the set. The error variance in any principal component is shown…
