The RizbA scale combines psychometrics and art theory and enables a measurement of pictorial expression. This study explores its factor structure and a potential gap between theory and empirics. A sample of 275 pictorial works by artists and nonprofessionals was rated by 179 art experts. Three CFA path models were specified: models A and B based…

Cultural variations in affective experiences are observed. Research on positive affect with refined categorizations has been limited. This study examined the Affect Valuation Theory and its measure, the Affect Valuation Index (AVI), using a sample of high school students from rural China (N = 676, M[subscript age] = 16.17 years, SD = 0.94). The…

The Strengths and Difficulties Questionnaire (SDQ) is a brief instrument developed primarily for screening children and adolescents for social-emotional learning. The SDQ contains four factors related to socio-emotional difficulties and one factor related to prosocial behaviour. However, studies of its factor structure have produced mixed results.…

The purpose of this research is to create a reliable and valid scale to assess AIlessphobia in Education (the fear of being without Artificial Intelligence in education) among university students. In three phases, a sample of 1378 undergraduate students from different faculties at a public university participated in the reliability and validity…

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…

Background: Individuals with intellectual disabilities are as vulnerable to depression as their typically developing peers. This study aimed to verify the reliability and validity of the Center for Epidemiologic Studies Depression Scale (CES-D) in individuals with intellectual disabilities and determine whether the scale is appropriate for…

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…
