Children live complex social lives that has various aspects, including intimate friendships, peer-acceptance and bullying dynamics which is usually studied separately in research. This study aims to investigate the interplays of these three important fields by analyzing the moderating effects of number of friendships on the relation between…

Normative studies are needed to obtain norms for comparing individuals with the reference population on relevant clinical or educational measures. Norms can be obtained in an efficient way by regressing the test score on relevant predictors, such as age and sex. When several measures are normed with the same sample, a multivariate regression-based…

The present research aims to examine whether the questions in the Program for the International Student Assessment (PISA) 2009 reading literacy instrument display differential item functioning (DIF) among the Turkish, French, and American samples based on univariate and multivariate matching techniques before and after the total score, which is…

Background: We examine the sensitivity of the Heyneman-Loxley Effect to the influence of an error-prone family background measure in 15 education systems from Southern and Eastern Africa. Our aim is to revisit a claim by Abby Riddell from the November 1989 issue of the "Comparative Education Review" concerning the reliability of family…

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 aim of this paper was to evaluate gender differences in the language used in United Nations (UN) General Assembly debates by one male and one female representative each from India, China, the USA, and Indonesia. The critical discourse analysis (CDA) framework of van Dijk (2015) was used along with the 25 discursive devices in this framework.…

The purpose of this study was to examine the psychometric properties of the goal orientation (GO) scale across job search contexts to facilitate its use in large and varied search settings. A sample of 720 job losers and new entrants' job seekers in Ghana completed the survey. Confirmatory factor analysis supported the three-factor theoretical…

Researchers are combining self-reports from mobile surveys with passive data collection using sensors and apps on smartphones increasingly more often. While smartphones are commonly used in some groups of individuals, smartphone penetration is significantly lower in other groups. In addition, different operating systems (OSs) limit how mobile data…

This study examined the interconnections between perceived teacher support, student selfregulation, and psychological well-being among undergraduate English majors in Iran (n = 347). Confirmatory factor analysis (CFA) validated the measurement model, demonstrating sound internal consistency as well as convergent and discriminant validity. Harman's…

The Digital Stress Scale (DSS) is used to measure digital stress, which is the perceived stress and anxiety associated with social media use. In this study, the Chinese version of the DSS was validated using a sample of 721 Chinese college students, 321 males and 400 females (KMO = 0.923; Bartlett = 5,058.492, p < 0.001). Confirmatory factor…

For decades, achievement goal theory has been extensively used, but empirical research still requires a clearer understanding of the underlying factors conceptualized and measured during secondary school periods. In light of the increasing use of longitudinal studies in motivation research, this study aims to investigate the longitudinal…

The objectives were to examine the factorial structure of the Academic Procrastination Scale-Short Form (APS-S) and the measurement invariance across gender and educational levels, to determine possible differences in procrastination across gender, educational levels, and grades. The sample was formed of 1486 Spanish primary and secondary school…

In research on math self-concept (MSC) formation, very few studies have juxtaposed the effects of math grades, math ability, school-average math grades, and school-average math ability. However, these factors are important in enabling Taiwanese senior school students to achieve proper MSC and choose a suitable academic track. Thus, the present…

Researchers attempting to survey refugees over time face methodological issues because of the transient nature of the target population. In this article, we examine whether applying smartphone technology could alleviate these issues. We interviewed 529 refugees and afterward invited them to four follow-up mobile web surveys and to install a…

In this article, we present the results of three question design experiments on inter-item correlations, which tested a grid design against a single-item design. The first and second experiments examined the inter-item correlations of a set with five and seven items, respectively, and the third experiment examined the impact of the question design…
