The purposes of this study were to test the structural validity and to test the parameters invariance of the self-discipline measurement model for good student citizenship among the models, using the data from the 1,047 complete questionnaires and the reducing length questionnaires with multiple matrix sampling technique. The sample size of this…

This study's primary aim is to validate a research instrument in Iraqi Kurdistan middle and secondary schools to explore learners' perspectives concerning social constructivist learning environments and e-learning outcomes. The research instrument was updated and devised based on Aldridge, Fraser, Taylor, and Chen's (Aldridge et al., International…

The factor structure of the Teacher-Child Rating Scale (T-CRS 2.1) was examined using confirmatory factor analysis (CFA). A cross-sectional study was carried out on 68,497 children in prekindergarten through Grade 10. Item reduction was carried out based on modification indices, standardized residual covariance, and standardized factor loadings. A…

As part of universal screening efforts in schools, validated measures that identify internalizing distress are needed. One promising available measure, the Depression, Anxiety, and Stress Scales-21 (DASS-21), has yet to be thoroughly investigated with adolescents in the United States. This study investigated the underlying factor structure of the…

The "Teacher Efficacy for Inclusive Practices" (TEIP) scale is designed to measure teacher-self efficacy to teach in inclusive classrooms. The original study identified three scale factors: "efficacy in using inclusive instruction" ("EII"), "efficacy in collaboration" ("EC"), and "efficacy in…

A procedure for examining essential unidimensionality in multicomponent measuring instruments is discussed. The method is based on an application of latent variable modeling and is concerned with the extent to which a common factor for all components of a given scale accounts for their correlations. The approach provides point and interval…

The purpose of this study is to further enhance the existing reliability and validity evidence related to the School Implementation Scale (SIS) and its use for evaluating the implementation of different integrated academic and behavior tiered Response-To-Intervention (RTI) models. Previous methodology conducted for validation of the instrument has…

Purpose: A new measure of sportspersonship, which differentiates between compliance and principled approaches, was developed and initially validated in 3 studies. Method: Study 1 developed items, assessed content validity, and proposed a model. Study 2 tested the factorial validity of the model on an independent sample. Study 3 further tested the…

Objective: This article examines the measurement invariance of "Family, School, and Peer Influence on Volunteerism Scale" (FSPV) across genders using the mean and covariance structure analysis approach. Method: A total of 2,845 Chinese high school adolescents aged 11 to 15 years completed the FSPV scale. Results: Results of the…

This paper focuses on the development and study of a framework to provide direction and guidance for practicing teachers in using a web-based case studies program for professional development in early reading; the program is called Case Studies Reading Lessons (CSRL). The framework directs and guides teachers' analysis of reading instruction by…

This study examines the reliability and validity of a Chinese-translated version of the Gifted Rating Scales-Preschool/Kindergarten Form (GRS-P) and explores the effect of gender and age on each of the subscales. Data were collected from 250 kindergarten children, with age ranging from 4 years, 0 months to 6 years, 11 months. Results indicated…

Exploratory factor analysis (EFA) of the Psychopathic Personality Inventory (PPI; S. O. Lilienfeld, 1990; S. O. Lilienfeld & B. P. Andrews, 1996) with a community sample has suggested that the PPI subscales may comprise 2 higher order factors (S. D. Benning, C. J. Patrick, B. M. Hicks, D. M. Blonigen, & R. F. Krueger, 2003). However,…

A plausible factorial structure for many types of psychological and educational tests exhibits a general factor and one or more group or method factors. This structure can be represented by a bifactor model. The bifactor structure results from the constraint that each item has a nonzero loading on the primary dimension and, at most, one of the…

The identification of two factors when one factor is expected is an artifact caused by using factor analysis on data that would be more appropriately analyzed with a unidimensional unfolding model. A numerical illustration is given, and ways to determine whether data conform to the unidimensional unfolding model are reviewed. (SLD)

Determines that the factor structure of the instructional model measured by the Michigan State University Student Instructional Rating System (SIRS) form could be replicated by an adapted version of the SIRS instrument at Florida State University. (Author)
