This paper reports an investigation into the psychometric properties of the COR-Advantage1.5 (COR-Adv1.5) assessment tool, a criterion-referenced observation-based instrument designed to assess the developmental abilities of children from birth through kindergarten. Using data from 8534 children participating in a state-funded preschool program…

This study aimed to introduce an ego-resiliency questionnaire for preadolescents (the ER-P) by restructuring the ER89 using the data of 1398 preadolescents from the Panel Study on Korean Children. The ER-P was proposed as a 10-item second-order instrument with two factors (Optimal Regulation and Openness to Life Experiences). The ER-P achieved…

The Frost Multidimensional Perfectionism Scale or FMPS is one of the first empirically validated measures of perfectionism. Cultural nuances demand that the efficiency of a short version of this scale, FMPS -- Brief, be tested on an Asian sample. Given the wealth of studies that consistently linked perfectionism to academic achievement, research…

In an attempt to measure the dynamic features of foreign language enjoyment (FLE), we adopted a longitudinal confirmatory factor analysis-curve of factors model (LCFA-CFM) approach to substantiate the validity of the original FLE scale (Dewaele and MacIntyre [(2014. "The Two Faces of Janus? Anxiety and Enjoyment in the Foreign Language…

This investigation utilized publicly available data from the High School Longitudinal Study 2009 (HSLS:09) by the National Center for Educational Statistics (NCES) to examine any latent structures among variables which may empirically support the validity and reliability of a mathematical sense of belonging (MSB) construct. Using the nationally…

The current study quantitatively applies Spolsky's triangular framework of language policy, including beliefs, practices, and management, to the family domain by investigating language policy in multilingual families in Belgium's Flemish Community. Firstly, we examine whether the three components in fact call for an independent description and…

This study examined the structure of the Best Start Kindergarten Assessment (Best Start) of literacy and numeracy, with the aim of confirming a two-factor measure of attainment at school entry comparable in structure to standardised measures of literacy and numeracy administered in later school years. Administrative data from the 2009 Best Start…

Given the longitudinal nature of L2 grit, the use of conventional research methodologies with cross-sectional data to examine the validity of L2 grit scale seems inadequate. The present research was an attempt to extend the domain-specific phase of research on L2 grit, with the pursuit of long-term goals at its core, into a dynamic one. Thus, we…

Research on assessing English as a foreign language (EFL) development has been growing recently. However, empirical evidence from longitudinal analyses based on substantial samples is still needed. In such settings, tests for measuring language development must meet high standards of test quality such as validity, reliability, and objectivity, as…

Reflection is a key component of the transformative learning process. In this study, we take steps to define components of reflection and link them to a computer-based, quantitative method of content analysis called Linguistic Inquiry and Word Count (LIWC). This method can be used to evaluate common forms of reflective writing such as journals,…

The "5 Cs of PYD Model" is an influential theory involving the role of Intentional Self-Regulation (ISR) in positive youth development (PYD). The model, which was developed with U.S. populations, has recently been used in other cultural contexts and, as such, the measurement invariance of the ISR-PYD model across cultural contexts must…

Youth mentoring relationships have significant potential for promoting positive youth development. Nonetheless, the benefits derived from such relationships depend considerably on the length and quality of the bonds that are created between mentors and youth. Although some attention has been paid to youth's experience of relationship quality, few…

Introduction: This longitudinal study designed and tested the validity of a new measure of pro-social risk taking -- risks that individuals take in order to help others. Methods: The sample was racially and ethnically diverse adolescents in the rural Southeastern United States (N = 867; Mage = 12.82 years, 10-14 years at Wave 1; 50% Girls, 33%…

Observations seem particularly susceptible to rater error due to the level of subjectivity involved in assessment. Thus, the present paper aims to investigate: (1) inter-rater agreement (IRA) using the Classroom Assessment Scoring System -- Secondary version (CLASS-S) and (2) the CLASS-S factor structure in a Norwegian context. Inter-rater…

The Utrecht-Management of Identity Commitments Scale (U-MICS) is one of the most-commonly used self-report scales to assess personal identity in studies of developmental processes. While it has been translated and validated in many countries around the world, evidence of its applicability in Greek is absent. The purpose of this study was to…
