The population relationship between coefficient alpha and scale reliability is studied in the widely used setting of unidimensional multicomponent measuring instruments. It is demonstrated that for any set of component loadings on the common factor, regardless of the extent of their inequality, the discrepancy between alpha and reliability can be…

Exploratory factor analysis is a statistical method commonly used in psychological research to investigate latent variables and to develop questionnaires. Although such self-report questionnaires are prone to missing values, there is not much literature on this topic with regard to exploratory factor analysis--and especially the process of factor…

Objective: To explore the symptomatic features of homesickness in Australian adolescent males during their first year at boarding school, as well as its dimensionality, coping strategies, and the relationship with academic, resilience, emotional and mental health factors. Method: Drawing on a larger, longitudinal study (n = 174 students), survey…

Ranking of scholarly journals is important to many parties. Studying the relationships among various ranking metrics is key to understanding the significance of one metric based on another. This research investigates the relationship among four major journal-ranking indicators: the impact factor (IF), the Eigenfactor score (ES), the "h."…

Students' conceptions of learning represent an influential factor for learning, yet the few existing studies used measures with limited validity and lacked to provide a model for middle school students. This research aimed to provide a preliminary validation of 'Learning Conception Questionnaire' (LCQ) by Liverta Sempio and Marchetti (2001) aimed…

When researchers fit statistical models to multiply imputed datasets, they have to fit the model separately for each imputed dataset. Since there are multiple datasets, there are always multiple sets of model results. It is possible for some of these sets of results not to converge while some do converge. This study examined occurrence of such a…

Purpose: In South Africa, the field of scale development and utilization in social work is referred to as "ecometrics," that is, the measurement of ecological constructs. There is, however, a lack of ecometric tools for social workers, particularly regarding strengths or resilience. Given the high vulnerability of South African youth,…

This study aimed to adapt to Turkish the measurement of work-leisure conflict developed by Tsaur et al. (2012) to measure work-leisure conflict and to present the causes and dimensions of the conflict and to develop a new study-leisure conflict scale for university students based on the items of this scale and to undertake reliability and validity…

Values in mathematics classroom is not commonly discussed, researched, implemented, and measured although value is a significant affective aspect of mathematics learning. In this article, it is proposed that an instrument is developed to measure the said values which will benefit the teaching and learning mathematics. Discussion will focus on the…

The Junior Metacognitive Awareness Inventory is a student self-report scale developed to correspond to a two-factor model of metacognition. Exploratory (N = 1,783) and confirmatory factor analysis (N = 942) were conducted using data from students in Grades 6 through 12 with results supporting two underlying factors corresponding to Knowledge and…

This study aimed to develop a self-report measure of pluralistic thought and practice. Following pilot development, a 23-item inventory was placed on an online survey site, and 474 participants satisfactorily completed the measure. Respondents were trainee or qualified therapists, predominantly female, based in the UK, and of a humanistic or…

Based upon self-concept and self-determination theory, the present study aimed to examine the measurement separability of young children's math self-concept (MSC) and six specific types of motivation, namely, intrinsic motivation (INTR), integrated motivation (INTEG), identified motivation (IDENT), introjected motivation, extrinsic motivation…

In response to calls to improve the quantitative training of undergraduate biology students, there have been increased efforts to better integrate math into biology curricula. One challenge of such efforts is negative student attitudes toward math, which are thought to be particularly prevalent among biology students. According to theory,…

Student resistance, which can briefly be defined as the tendency to resist teaching activities, is student's reacting to the teaching-learning activities, teachers, or administrators knowingly and wilfully, many times intentionally in various ways. Resistance behaviours, which could be considered as the outpouring of the anger created by the…

A latent variable modeling procedure is discussed that can be used to test if two or more homogeneous multicomponent instruments with distinct components are measuring the same underlying construct. The method is widely applicable in scale construction and development research and can also be of special interest in construct validation studies.…
