Ensuring construct comparability is a prerequisite for testing cross-group differences, yet this assumption is rarely tested in mentoring research. More studies testing for factorial invariance are needed for the construct validation of mentoring. Multiple group confirmatory factor analyses (CFAs) were used to investigate the factorial stability…

The factor analysis of ordered-categorical measures has been described in the literature on factor analysis, but the extension of the analysis to the multiple-population case is less well-known. For example, a comprehensive statement of identification conditions for the multiplepopulation case seems absent in the literature. We review this…

Single constructs measured using positively and negatively worded items are often incompatible with a congeneric model, but require 2 correlated factors. Imperfect correlation entails that 2 independent dimensions are required for representing the true variance. If 2 dimensions are sought, how can they be interpreted? This study shows how to…

This study describes the development of the Mathematics Interest Inventory. Internal reliability and concurrent and construct validity were evaluated using 3 samples of children totaling 724. Exploratory and confirmatory factor analyses revealed the presence of 3 factors representing the psychological state of individual interest. Cross-validation…

The "Decision-Making Questionnaire" (DMQ) was developed and validated in order to examine the factors that affect decision making. The investigation was carried out with two samples, one of 170 participants and the other of 425 of both sexes. Each sample was divided into three age ranges: young students (18-25 years), adults (26-60…

There is the need for a reliable and valid measure to facilitate emotional intelligence (EI) research on international college students (ICSs). The present study examined the factorial invariance of the Wong and Law Emotional Intelligence Scale (WLEIS), a trait EI measure, in a sample of 628 ICSs. A web-based survey was developed to facilitate…

The present study investigated the factor structure of a field trial sample of the Test of English as a Foreign Language™ Internet-based test (TOEFL® iBT). An item-level confirmatory factor analysis (CFA) was conducted for a polychoric correlation matrix of items on a test form completed by 2,720 participants in the 2003-2004 TOEFL iBT Field…

This study investigated the factor structure of motivational constructs as expressed by older adult learners and examined how these constructs correlated with selected socio-demographic characteristics at the National Open University of Taiwan (NOUT). Results were based on the responses of 371 elders to the 32-item Reasons for Participation Scale…

This paper concerns the divisibility of comprehension subskills measured in L2 listening and reading tests. Motivated by the administration of the new Web-based English as a Second Language Placement Exam (WB-ESLPE) at UCLA, this study addresses the following research questions: first, to what extent do the WB-ESLPE listening and reading items…

Although Sense of Community (SOC) is usually defined as a multidimensional construct, most SOC scales are unidimensional. To reduce the split between theory and empirical research, the present work identifies a multifactor structure for the Italian Sense of Community Scale (ISCS) that has already been validated as a unitary index of SOC. This…

This study examined the structure of perceived multiple intelligences of 1,464 Chinese gifted students using the Student Multiple Intelligences Profile. To evaluate whether perceived multiple intelligences could be applied adequately across boys and girls, a model hypothesizing different degrees of equivalence across the two gender groups was…

Although gender issues have been addressed in clinical drug abuse literature, very little research has focused on gender differences in terms of the psychometric properties of assessment instruments. If boys and girls interpret instruments differently, the accuracy of clinical evaluation, referral, and treatment decisions based on these measures…

Nonlinear factor analysis is a tool commonly used by measurement specialists to identify both the presence and nature of multidimensionality in a set of test items, an important issue given that standard Item Response Theory models assume a unidimensional latent structure. Results from most factor-analytic algorithms include loading matrices,…

The psychometric properties of the Adult Manifest Anxiety Scale-Elderly Version (AMAS-E) scores were evaluated in two studies. In Study 1, the temporal stability and construct validity of the AMAS-E test scores were examined in a group of 226 older adults, aged 60 years and older. Results indicated adequate to excellent temporal stability (2-week…

Although researchers have demonstrated a link between teacher autonomy and teacher motivation, job satisfaction, stress (burnout), professionalism, and empowerment, the task of identifying the underlying theoretical dimensions of teacher autonomy has met with varied results. The authors verified the existing 2-factor structure of the Teaching…
