The objective of this study was to provide empirical evidence to support psychometric properties of a modified four-dimensional model of the Leadership Scale for Sports (LSS). The study tested invariance of all parameters (i.e., factor loadings, error variances, and factor variances-covariances) in the four-dimensional measurement model between…

Pointing to declines in self-reported criminality across waves of the National Youth Survey, several researchers have concluded that "testing effects" may render longitudinal self-report data unreliable. This article argues that the issue remains unsettled on two accounts. First, alternative explanations for the declines have not been fully…

The population sensitivity of vertical scaling results was evaluated for a state reading assessment spanning grades 3-10 and a state mathematics test spanning grades 3-8. Subpopulations considered included males and females. The 3-parameter logistic model was used to calibrate math and reading items and a common item design was used to construct…

The purpose of this study was to develop and validate the Concerns about Counseling Racial Minority Clients (CCRMC) scale among counselor trainees. Sample 1 was used for an exploratory factor analysis and confirmatory factor analysis. Four factors were identified, Managing Cultural Differences ([alpha] = 0.82), Offending or Hurting Clients…

Objective: Health locus of control (HLC) is associated with health behaviours. We aimed to investigate the difference of HLC to understand the potential gap in health beliefs between physicians and the general public. Design and setting: Physicians and the general public were surveyed in Japan using a cross-sectional survey. Data on the Japanese…

The following paper describes the development of an instrument designed to assess middle school students' interest in statistical literacy. The paper commences with a review of the literature as it relates to interest in this context and then proposes a theoretical model upon which the proposed instrument is based. The Rasch Rating Scale model is…

The Test of Logical Thinking (TOLT) and the Group Assessment of Logical Thinking (GALT) are two of the instruments most widely used by science educators and researchers to measure students' formal reasoning abilities. Based on Piaget's cognitive development theory, formal thinking ability has been shown to be essential for student achievement in…

Keeley, Smith, and Buskist (2006) investigated the psychometric properties of the Teacher Behavior Checklist (TBC), but did not provide evidence that the measure could differentiate among teachers. This study required students at 2 schools to rate their best professor, worst professor, and most recent professor on the TBC. We found highly similar…

This article reviews a possibility to assess university studies as a service. University studies have to be of high quality both in their content and in the administrative level. Therefore, quality of studies as a service is an important constituent part of study quality assurance. When assessing quality of university studies as a service, it is…

This article reports the results of a study of potential sources of item nonequivalence between English and Chinese language versions of a cognitive development test for preschool-aged children. Items were flagged for potential nonequivalence through statistical and judgment-based procedures, and the relationship between flag status and item…

The need to develop measures that tap into constructs of interest to social work, refine existing measures, and ensure that measures function adequately across diverse populations of interest is critical. Item response theory (IRT) is a modern measurement approach that is increasingly seen as an essential tool in a number of allied professions.…

Financial stress is commonly experienced among college students and is associated with adverse academic, mental health, and physical health outcomes. Surprisingly, no validated measures of financial stress have been developed for undergraduate populations. The present study was conducted to generate and evaluate a measure of financial stress for…

Most computerized adaptive tests (CAT) have been studied under the framework of unidimensional item response theory. However, many psychological variables are multidimensional and might benefit from using a multidimensional approach to CAT. In addition, a number of psychological variables (e.g., quality of life, depression) can be conceptualized…

State coordinators of early hearing detection and intervention (EHDI) programs completed a strengths, weaknesses, opportunities, and threats, or SWOT, analysis that examined 12 areas within state EHDI programs. For audiological evaluation and services, 299 items were listed by 49 coordinators, and themes were identified within each SWOT category.…

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…
