Although many textbooks on multivariate statistics discuss the common factor analysis model, few of these books mention the problem of factor score indeterminacy (FSI). Thus, many students and contemporary researchers are unaware of an important fact. Namely, for any common factor model with known (or estimated) model parameters, infinite sets of…

A sample suffers range restriction (RR) when its variance is reduced comparing with its population variance and, in turn, it fails representing such population. If the RR occurs over the latent factor, not directly over the observed variable, the researcher deals with an indirect RR, common when using convenience samples. This work explores how…

Despite several theoretical, structural, and statistical issues reported against Five Facets Mindfulness Questionnaire (FFMQ), most studies in the educational sector of Pakistan use it without analyzing its factor structure. Since culture might change the structure, this first systematic study filled the gap and explored the factor structure of…

Counseling and non-counseling duties were investigated. The Assessment of School Counselor Needs for Professional Development (ASCNPD; Dahir & Stone, 2003, 2004) was used to examine the practices of 1,244 school counselors to determine the prevalence of the activities among school counselors. Principal component analysis indicated a two-factor…

We examine the factor structure of scores from the CLASS-S protocol obtained from observations of middle school classroom teaching. Factor analysis has been used to support both interpretations of scores from classroom observation protocols, like CLASS-S, and the theories about teaching that underlie them. However, classroom observations contain…

The primary objective of this cross-cultural investigation is to compare patterns in student responses to an empirically scrutinized character education measure administered to students in four school districts in Florida with students in a school in Kenya. In this way, the generalizability of findings for scale scores could be compared across…

This study analyses the influence of ethnic identity on the acculturation orientations of Basque undergraduates, towards groups in traditional contact (native Basques and native Spaniards) and towards recent immigrant groups. Five dimensions were used to measure the Basque and/or Spanish identities: linguistic, cultural, political, global, and the…

The Stressors about Practicum Inventory, a self-report measure of perceived stressors about the practicum, was designed to provide those responsible for the training of primary school teachers with an informative, inexpensive and psychometrically sound tool. The present study describes the development and validation of the 94-item inventory in a…

The Strengths and Difficulties Questionnaire (SDQ) is an instrument developed by Goodman for screening child and adolescent psychopathology. The aim of this study is to contribute to the analysis and validation of the internal structure of the Italian SDQ teacher version (SDQ-T). The SDQ-T was completed by 301 teachers, evaluating 3,302 children…

This study examined the relationship between individual and family perfectionism and mental health functioning among two hundred and seven Latino college students. One aim of this study was to test the factor structure of the Almost Perfect Scale-Revised (APS-R; Slaney, Rice, Mobley, Trippi, & Ashby, 2001) with Latino college students by…

The purpose of this study was to evaluate the common assumption that teachers of color (TOC) are more culturally competent than White teachers by assessing physical education teachers' cultural competency. A secondary purpose was to ascertain the possible differences in cultural competence levels of White teachers in diverse school settings versus…

Treating Likert rating scale data as continuous outcomes in confirmatory factor analysis violates the assumption of multivariate normality. Given certain requirements pertaining to the number of categories, skewness, size of the factor loadings, and so forth, it seems nevertheless possible to recover true parameter values if the data stem from a…

We assessed whether and how the discourse written for prototype integrated tasks (involving writing in response to print or audio source texts) field tested for the new TOEFL® differs from the discourse written for independent essays (i.e., the TOEFL essay). We selected 216 compositions written for 6 tasks by 36 examinees in a field…
