Previous confirmatory factor analytic research that has examined the factor structure of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) has endorsed either higher order models or oblique factor models that tend to amalgamate both general factor and index factor sources of systematic variance. An alternative model that has not yet…

Confirmatory factor analysis was used to determine the factor structure of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) scores of 297 children referred to a children's hospital in the Southwestern United States. Results support previous findings that indicate the WISC-IV is best represented by a direct hierarchical…

This paper seeks mainly to contribute to the debate on how the relative degree of development of a country should be measured by proposing an indicator to build on the valuable starting point provided by the Human Development Index (HDI). The indicator proposed is called the "Composite, Dynamic Human Development Index". It incorporates in a simple…

Research validating mindfulness-based interventions with youths and in schools is growing, yet research validating measures of youths' mindfulness in schools has received far less empirical attention. The present study makes the case for and reports on the preliminary development and validation of a new, 15-item, multidimensional, self-report…

The Resiliency Scale for Young Adults (RSYA) is presented as an upward extension of the Resiliency Scales for Children and Adolescents (RSCA). The RSYA is based on the "three-factor model of personal resiliency" including "mastery," "relatedness," and "emotional reactivity." Several stages of scale…

This article reports on the development and initial validation of the Culturally Responsive Classroom Management Self-Efficacy Scale. Data from 380 preservice and inservice teachers were used to examine the psychometric properties of the instrument. Exploratory factor analysis results suggested a one-factor structure consisting of 35 items and the…

University life can be stressful and students may struggle to adjust socially. We examined students' social achievement goals--their orientations towards their relationships with their peers--as one important factor underlying students' social and psychological adjustment in college. When investigating the direct and indirect effects of social…

The era of "digital literacy" raises the question of whether the meaning of reading interest may have changed. This study examined psycho-behavioral dimensions of reading interest as these relate to different reading modes and different purposes of reading. Findings show that reading interest is best represented by its subcomponents of…

This quantitative pilot-study empirically tested the factor structure and reliability of the newly developed Graphical Inventory of Ethical Leadership (GIEL) scale, a Likert-style scale for quantifying key concepts related to ethical leadership. Correlations and principal components analyses were performed using pre-existing data as self-reports…

This study aimed to develop a valid and reliable measurement tool to enhance ethical evaluation literature. The tool consists of two subscales named "Bases of ethical evaluation," and "Grounds of ethical evaluation." In order to determine the factor structure of the scales, both exploratory and confirmatory factor analyses were…

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…

The 'terrible twos' are often associated with increased temper tantrums, noncompliance and aggression. Although some expression of these behaviors is normal, whether early individual factors can predict which children are most at risk of frequent or prolonged emotional and behavioral problems is of increasing interest. The current study of 6,067…

We examined the theoretical factor structure fit and psychometric properties of the "Transition Assessment and Goal Generator" (TAGG). In the first study, 349 transition-aged students with disabilities, their special educators, and family members completed TAGG assessments, and using exploratory factor analysis (EFA)/confirmatory factor…

Background: Learning strategies are considered a key aspect for academic performance not only for science, technology, engineering and mathematics (STEM) students. Refining their assessment thus constitutes a worthwhile research purpose. The aim of this study is to examine the 69-item LIST questionnaire ("ZDDP" 15:185-200, 1994) with the…

Various studies on the conceptual framework of perfectionism construct use Hewitt Multi-dimensional Perfectionism Scale (HMPS), as a basic approach. The measure has a prominent role with respect to the theoretical considerations of perfectionism dimensions. This study aimed to evaluate the psychometric properties of the Turkish version of the…
