In exploratory factor analysis, although the researchers decide which items belong to which factors by considering statistical results, the decisions taken sometimes can be subjective in case of having items with similar factor loadings and complex factor structures. The aim of this study was to examine the validity of classifying items into…

Introduction: This article has two objectives: a) to examine the factorial structure of the Spanish version of the EPQR-A through an exploratory factor analysis and b) to perform a confirmatory factor analysis to determine the psychometric properties of the Spanish version of the EPQR-A in terms of construct validity in an adult academic…

The aim of this study was to assess the reliability and validity of ERQ in a group of Egyptian adolescents. 648 adolescents from middle schools in Nasr city, Egypt were recruited. These adolescents aged 14-15 years old (M=14.4, SD=2.22). Of which,400 were females (61.72%) while 248 were males (38.27%). Exploratory Factor Analysis, with CFA and…

In exploratory item factor analysis (IFA), researchers may use model fit statistics and commonly invoked fit thresholds to help determine the dimensionality of an assessment. However, these indices and thresholds may mislead as they were developed in a confirmatory framework for models with continuous, not categorical, indicators. The present…

Educators' Social-Emotional Learning (SEL) is crucial for fostering positive, supportive, and effective learning environments. This study seeks to improve SEL assessment among educators by addressing limitations of the previous EduSEL questionnaire. Study 1 established convergent validity by comparing EduSEL with a validated SEL questionnaire.…

This study is the first to investigate and validate the psychometric properties of an Indonesian translation of the Student Performance Opportunity of Competence Development (SPOCD) questionnaire that covers five key competencies related to the mathematics learning process, namely: (1) thinking; (2) relating to others; (3) using language, symbols…

The purpose of this study was to examine the psychometric properties of Cognitive Emotion Regulation Questionnaire (Garnefski, Kraaij et al., 2002), using a sample of adolescents from Egypt, aged 13, 14 and 15 years. The results indicate that the nine-factor model was successful, obtaining adequate fit indexes: X[superscript 2], df=381.3,…

Intercultural competence is a crucial element of foreign language education, yet the multifaceted nature of this construct makes it inherently difficult to assess. Although several tools for evaluating intercultural competence currently exist, research on their use in secondary school settings is scarce. This study reports on the development and…

Valid and reliable instruments are required to appropriately study perfectionism. With this in mind, three studies are presented that describe the development and initial validation of a new instrument designed to measure multidimensional performance perfectionism for use in sport (Performance Perfectionism Scale--Sport [PPS-S]). The instrument is…

The purpose of this study is to validate the widely adopted Teachers' Sense of Efficacy Scale (TSES) for the East Asian context. The researchers seek to find out whether TSES holds validity and reliability and is appropriate for use to measure teacher efficacy in China, Korea, and Japan. 489 teachers from the three countries participated in the…

Conventional differential item functioning (DIF) detection methods (e.g., the Mantel-Haenszel test) can be used to detect DIF only across observed groups, such as gender or ethnicity. However, research has found that DIF is not typically fully explained by an observed variable. True sources of DIF may include unobserved, latent variables, such as…

Many psychological scales written in the Likert format include reverse worded (RW) items in order to control acquiescence bias. However, studies have shown that RW items often contaminate the factor structure of the scale by creating one or more method factors. The present study examines an alternative scale format, called the Expanded format,…

In this study, we sought to confirm the theoretical framework underlying an Online Graduate Mentoring Scale by establishing the scale's factorial validity and reliability. Analysis of data received from doctoral students and alumni/ae of the College of Education of one large, online, accredited university reduced the initial theoretical…

The Colorado Learning Attitudes about Science Survey (CLASS) is a widely used instrument designed to measure student attitudes toward physics and learning physics. Previous research revealed a fairly complex factor structure. In this study, exploratory and confirmatory factor analyses were conducted on data from an undergraduate introductory…

Objective: This article examines the measurement invariance of "Family, School, and Peer Influence on Volunteerism Scale" (FSPV) across genders using the mean and covariance structure analysis approach. Method: A total of 2,845 Chinese high school adolescents aged 11 to 15 years completed the FSPV scale. Results: Results of the…
