When performing regression analysis, one way to examine the normality of data is to screen outliers. Outliers, on the other hand, do not always have an effect on regression results. In reality, cases with a large amount of residuals that affect regression analysis results are referred to as influential cases. It is important to detect them in the…

The purpose of this study is to identify which scale short-form development method produces better findings in different factor structures. A simulation study was designed based on this purpose. Three different factor structures and three simulation conditions were selected. As the findings of this simulation study, the model-data fit and…

There is an expectation that health professions schools respond to priority societal health needs. This expectation is largely based on the underlying assumption that schools are aware of the priority needs in their communities. This paper demonstrates how open-access, pan-national health data can be used to create a reliable health index to…

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…

In China there is an increasing need for suitable measures to evaluate clinical outcomes in adolescents' psychological counselling processes. To satisfy this purpose, this study evaluated the Young Person's Clinical Outcomes in Routine Evaluation (YP-CORE)'s psychometric properties in a Chinese context with two groups: psychiatric outpatients…

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…
