School counselors play an integral role in fostering students' noncognitive skills (e.g., social/emotional skills, mindsets) identified within the American School Counselor Association Mindsets & Behaviors Standards. We analyzed responses from a sample of 1484 high school students to explore the factor structure of the "School Counselor…

The purpose of this study is to examine the validity of the scale for identifying gifted children, whose validity was proven by exploratory, confirmatory factor analysis, and whose reliability was proven the Cronbach alpha coefficient for identifying children in the 3-6 age group, using Mokken scaling based on nonparametric item response theory.…

This Monte Carlo simulation study aimed to investigate confirmatory factor analysis (CFA) estimation methods under different conditions, such as sample size, distribution of indicators, test length, average factor loading, and factor structure. Binary data were generated to compare the performance of maximum likelihood (ML), mean and variance…

An exploration of factor analytic structure of the conceptions of mathematics scale among pre-service mathematics teachers in South-West Nigeria was conducted as evidence suggests paucity of research on psychometric properties of the conceptions of mathematics scale in Nigeria. This article through instrumentation research methodology reports the…

With increasing attention to examining cognitive strengths and achievements related to social and emotional variables, it is imperative that instruments developed and used to assess change be valid and reliable for measuring underlying constructs. This study examines instruments identified and/or developed to measure four noncognitive constructs…

The aim of this study is to develop a scale of pre-service teacher beliefs about Ottoman Turkish. The 34-item "The Scale of Teacher Candidate Beliefs about Ottoman Turkish," created for the piloting was given to 202 pre-service teachers who were taking an Ottoman Turkish course in the departments of Turkish education and Arabic education…

Development of the Jordan Performance Appraisal System (JPAS) was completed in 1996. This study examined the factor structure of the classroom observation instrument used in the JPAS. Using observed classroom instructional quality ratings of 1220 elementary teachers of Grades 1-6 in the Jordan School District, this study estimated the factor…

No matter how strong the theoretical infrastructure of a study is, if the measurement instruments do not have the necessary psychometric qualities, there will be a question of trust in interpreting the findings, and it will be inevitable to make wrong decisions with the results. One of the important steps in scale development/adaptation studies is…

The aim of the present research was to validate the Scale of motivation for choosing teaching profession (SMVUP-4-S), and to explore its basic psychometric properties on a sample of Slovak teacher trainee students. SMVUP-4-S scale was completed by 1235 respondents with a mean age of 20.1 years. SMVUP-4-S scale consists of 44 items arranged into 11…

This study was designed to evaluate the dimensionality, internal consistency, and validity of scores on the Arabic Post-Traumatic Growth Inventory--Short Form (PTGI--SF). This brief 10-item form of the PTGI self-report measure was administered to a sample of Arabic-speaking professional helpers (N = 338) working in Israel, Gaza, and the West Bank.…

We used multilevel factor analyses to investigate the structure of the Teacher as Social Context Questionnaire (TASCQ)-short form--a prominent measure of teacher practices that promote student motivation to learn. Based on Self-Determination Theory (SDT), the TASCQ contains three scales: Autonomy Support, Structure, and Involvement. Few studies…

Universal screening for behavioral/mental health risk is a critical component of multitiered systems of support, allowing for early identification of students in need of prevention and/or intervention services. The Student Risk Screening Scale (SRSS; Drummond, 1994) is one commonly used universal screening tool intended to measure externalizing…

This article aims to adapt and validate the Risk-Taking and Self-Harm Inventory for Adolescents (RTSHIA) in Portuguese. Results confirm the 2-factor structure originally proposed (risk-taking and self-harm). Both dimensions presented an adequate internal reliability and temporal stability. Convergent validity and sociodemographic differences are…

The purposes of this study were to test the structural validity and to test the parameters invariance of the self-discipline measurement model for good student citizenship among the models, using the data from the 1,047 complete questionnaires and the reducing length questionnaires with multiple matrix sampling technique. The sample size of this…

When item scores are ordered categorical, categorical omega can be computed based on the parameter estimates from a factor analysis model using frequentist estimators such as diagonally weighted least squares. When the sample size is relatively small and thresholds are different across items, using diagonally weighted least squares can yield a…
