Reliability indicates the internal consistency of a test. In educational studies, reliability is a key feature for a test. Researchers have proposed many traditional reliability estimates, such as coefficient alpha and coefficient omega. However, traditional reliability indices do not deal with the data hierarchy, even though the multilevel…

Schools and education systems are being challenged to improve the evaluation of teacher professional development, yet there is a lack of practical tools for doing so. This article describes the development and validation of a new instrument to assess teachers' perceptions of the impact of professional development. This instrument, designed to be…

Counselors and marriage and family therapists work with individuals, couples, and families on issues related to sexuality. However, clinicians may be underserving their clients by "not" having adequate training and preparation to work with clients with these presenting issues. One mitigating factor in the treatment of sexual problems is…

The article presents the construction and validation process of a questionnaire designed to study student teachers' beliefs about cultural diversity. The study, beyond highlighting the complexity involved in the study of beliefs, emphasises their relevance in implementing inclusive educational processes that guarantee the right to a good education…

The Liebowitz Social Anxiety Scale (LSAS) is one of the most commonly used measures of social anxiety symptoms. To date, no study has examined its psychometric properties in a Latino sample. The authors examined the reliability, temporal stability, and convergent validity of the LSAS in 73 Latinos diagnosed with an anxiety disorder. The original…

Behavior rating scales aid in the identification of problem behaviors, as well as the development of interventions to reduce such behavior. Although scores on many behavior rating scales have been validated in the United States, there have been few such studies in other cultural contexts. In this study, the structural validity of scores on a…

This research describes the development and psychometric evaluation of the Anti-Bisexual Experiences Scale (ABES). Items were developed on the basis of prior literature, revised on the basis of expert feedback, and submitted to psychometric evaluation. Exploratory factor analysis of data from 350 bisexual participants yielded 3 factors of reported…

The purpose of this study is to determine online self-regulated learning levels of students by adapting "Online Self-Regulated Learning Scale" designed by Barnard and his colleagues into Turkish. Present study, irrespective of being a scale analysis, is at the same time a qualitative research. It is executed via scan model. Study group…

The present study was designed to examine the construct validity, reliability, item difficulties, discrimination indices, effectiveness and efficiency of the CCAT test. (Author)

This paper examines the construct generality of five self-report measures of anxiety across male and female samples, and illustrates the use of confirmatory maximum likelihood techniques for examining factorial invariance. (Author/BW)

Empirical results from two studies--a simulation study and an experimental one--indicated that, in achievement data of the problem-solving type where a specific subject matter area is being tested, the greater the variety of the algorithms used, the higher the dimensionality of the test data.

The results of this study do not indicate any relationship between a child's performance on a creativity test and certain personality factors contributing to creativity, as measured by the Torrance Test of Creative Thinking and the CPQ. At both third and fourth grade levels, scores for the same child on the two tests were independent of each…

The Standardized Letter of Recommendation (SLR), a 28-item form, was created by ETS to supplement the qualitative rating of graduate school applicants' nonacademic qualities with a quantitative approach. The purpose of this study was to evaluate the following psychometric properties of the SLR using the Rasch rating-scale model: dimensionality,…
