The Multidimensional Personality Questionnaire (MPQ) measures a wide range of personality traits associated with affect and temperament. However, the lengthy administration time may have hindered its widespread use in personality research. The National Survey of Midlife Development in the United States (MIDUS) has adapted a short version of the…

Determining the number of factors in exploratory factor analysis (EFA) is crucial because it affects the rest of the analysis and the conclusions of the study. Researchers have developed various methods for deciding the number of factors to retain in EFA, but this remains one of the most difficult decisions in the EFA. The purpose of this study is…

Several validated adult autism symptom screening tools exist; however, there are concerns about the validity of instruments in adults who self-identify and those who have an autism diagnosis. This study evaluated the psychometric properties of the RAADS-R and RAADS-14 across gender, autism diagnosis and autistic identity, and age among a sample of…

"Grit" is a stable and measurable trait. It refers to the individual's ability to maintain efforts and interest in projects that take time to complete and are useful in educational contexts. In this study we investigated the validity of a short version of the Grit |International Assessment Scale, Portuguese Version (EAGrit-LP) based on…

The procedures of carrying out factorial invariance to validate a construct were well developed to ensure the reliability of the construct that can be used across groups for comparison and analysis, yet mainly restricted to the frequentist approach. This motivates an update to incorporate the growing Bayesian approach for carrying out the Bayesian…

Metacognition awareness is a fundamental skill for the 21st century. Accurately measuring metacognitive awareness would be highly relevant regardless of age, background, or cognitive abilities. The current study aimed to evaluate the psychometric properties of the 19-item Metacognitive Awareness Inventory-Arabic version (MAI-A) in the general…

Objective: This study sought to examine the factor structure, internal consistency, and measurement invariance of the Brief Resilience Scale (BRS) and the Multidimensional Scale of Perceived Social Support (MSPSS) among older sexual minority women with disabilities. Method: Participants (n = 208) consisted of sexual minority women aged 55 and…

There has been an increase in peer violence in Vietnam. Although normative beliefs approving aggression have been considered an important factor in the development of peer violence in Western countries, few studies examine the factor in Vietnamese context. This limitation may be due to the lack of a validated scale used to evaluate the factor. The…

Education professionals' conceptions of assessment can influence how they enact assessment with children. In this study, we explored the factor structure of a previously validated survey instrument, Brown's Conceptions of Assessment Questionnaire (COA-III), when administered to a social-media-based sample of 241 U.S. early childhood professionals.…

The goal of this study was to examine the factorial structure, internal consistency, test-retest reliability, criterion validity, convergent validity, and discriminant validity of the Brief Strengths Scale-12 (BSS-12) in Korean population. The Korean sample comprised 288 college students (68.1% were female), ranging in age 19 to 30 years (mean age…

Research suggests the need to assess both positive and negative forms of student engagement. The purpose of this study was to pilot disaffection items with the Student Engagement Instrument (SEI) with a sample of middle school students from a rural area in the Southeastern U.S. This study explored the factor structure of the piloted items…

Validity in psychometrics refers to the degree to which evidence and theory supports the interpretations drawn from a test, and Messick's Contemporary Validity Theory (1994) includes several facets with well-established evidence collection methods. However, there is a lack of consensus on appropriate methods of evaluating the facet of…

This study aims to investigate the psychometric properties of the Greek version of Brief Self-control Scale (BSCS). This scale is used for the assessing of self-control, which is the ability to control one's emotions and desires -- especially in demanding situations-in order to have more important long-term benefits. Data were collected from a…

The purpose of this study is to develop a valid and reliable measurement tool to determine the level of fear of missing out (FoMO) for university students. There are many studies aiming to determine the FoMO levels of adolescents, youth and university students. However, a new scale was needed since the scales used in these studies were the adapted…

In many psychological and educational applications, it is imperative to obtain valid and reliable score estimates of multilevel processes. For example, in order to assess the quality and characteristics of high impact learning processes, one must compute accurate scores representative of student- and classroom-level constructs. Currently, there…
