The patient health questionnaire-9 (PHQ-9) is widely utilized in assessing individuals' depression levels. Nevertheless, research regarding its factor structure and measurement invariance remains inadequate. The aim of this study was to delve into the factor structure of the PHQ-9 and to further investigate its measurement invariance across gender…

This study aims to compare the results of the factor analysis performed with Frequentist and Bayesian approaches. The number of sub-dimensions of the measurement tool obtained from different methods, the variation of the items in the sub-dimensions, and the fit statistics' differentiation were examined. 778 students constitute the study sample.…

The research in the field of positive psychology is alive for children and adolescents, and especially the effects of intervention studies are promising. While a large number of instruments exist for adults, there is a need for greater attention to basic measurement work of constructs for children. The Satisfaction With Life Scale is one of the…

There is considerable variability in the extent to which young people with developmental language disorder (DLD) experience mental health difficulties. What drives these individual differences remains unclear. In the current article, data from the Twin Early Development Study were used to investigate the genetic and environmental influences on…

The motivated strategies for learning questionnaire (MSLQ) is widely used as a self-report instrument to assess students' motivation and self-regulation. This study utilized the MSLQ Junior High to examine the motivational beliefs and self-regulation of secondary school students (Grades 8 and 9) from Singapore. The instrument was slightly modified…

The purpose of this study was to develop an abbreviated version of the Perceived Motivational Climate in Exercise Questionnaire (PMCEQ-A) to provide a more practical instrument for use in applied exercise settings. In the calibration step, two shortened versions' measurement and latent model values were compared to each other and the original…

Research Findings: Despite it being a widely accepted measure of social, emotional, and behavioral problems among children and young people, the factor structure underlying the Strengths and Difficulties Questionnaire (SDQ) is contested. Recent research has suggested a need to consider methodological bias in the SDQ, associated with the positive…

Hong Kong (HK) and the People's Republic of China (PRC), while sharing historic cultural roots, have different policies for and practices of educational assessment. Student conceptions of assessment function to guide individual behaviour in response to the functions, purposes, and consequences of assessments. A new self-report questionnaire was…

Research on attachment in adult relationships has included minimal studies to encompass a Hispanic population. Mexican Americans have specific characteristics grounded in historical, demographic, and family contexts which are different from other groups. Therefore, cross-cultural validation of instruments to assess family relationships increases…

Prior research has shown that classroom-based evaluation tools are unable to adequately capture the unique aspects of online courses. To address such challenges, a mid-sized Canadian university with a broad and diverse programme of online offerings adapted a questionnaire designed to assess constructivist-compatible online teaching practices. This…

The purpose of this study was to examine the internal reliability, factorial validity, and measurement invariance of a Brazilian-Portuguese version of the General Health Questionnaire-12 (GHQ-12) across clinical and nonclinical groups. The clinical sample consisted of 228 chronic hemodialysis patients (41.7% female), with a mean age of 48.23 (SD =…

The current study applied the person-fit statistic, l[subscript z], to data from a Canadian provincial achievement test to explore the usefulness of conducting person-fit analysis on large-scale assessments. Item parameter estimates were compared before and after the misfitting student responses, as identified by l[subscript z], were removed. The…

Engineers and policymakers have expressed concern that too few students enter the engineering pipeline. This has led to many efforts to engage students in engineering in after-school programs, summer programs, and more recently, in school curricula. The expectation is that, through these efforts, greater numbers of more demographically diverse…

The present study has two main interests. First, some pending issues about the psychometric properties of the CTAC (an anxiety questionnaire for blind and visually-impaired people) are assessed using item response theory (IRT). Second, the linear model is compared to the graded response model (GRM) in terms of measurement precision, sensitivity…

The "e-rater"® automated essay scoring system is used operationally in the scoring of the argument and issue tasks that form the Analytical Writing measure of the "GRE"® General Test. For each of these tasks, this study explored the value added of reporting 4 trait scores for each of these 2 tasks over the total e-rater score.…
