Despite the high prevalence of depression and other mental illnesses in autistic adults, screening instruments such as the Patient Health Questionnaire (PHQ-9) have not been specifically validated in an autistic sample. Using data from two Autism CRC longitudinal studies (n = 581), confirmatory factor analysis supported the two-factor model…

The current study reports the evidence for the reliability (via coefficient [alpha], coefficient [omega]) and validity (via confirmatory factor analysis, correlations) of the Teacher Efficacy for Promoting Partnership measure. Participants were 255 in-service Head Start educators from all Head Start regions across the United States. Educators were…

Background: Prior researchers developed an instrument to measure perceived design thinking ability of first-year students interested in engineering, and they validated the instrument through exploratory factor analysis. Purpose/Hypothesis: Our study uses the previously developed instrument to evaluate perceived design thinking ability of senior…

Recent studies report that students' attitudes toward statistics play an important role in their statistics achievement. The goal of this study was to test the psychometric properties of the "Survey of Attitudes Towards Statistics" (SATS-28) among undergraduate health science students enrolled in an introductory statistics course. Most…

Within mixed methods research, a key issue is how to mix qualitative and quantitative research orientations. Similar debates arise within a mixed method called Q methodology [Q] that has an 80-year history and strong qualitative leanings. Q is often identified with the sorting of statements and the factor analysis (grouping) of people with similar…

The Adapted Skillstreaming Checklist measures social/social-communication skills and behavioral flexibility/regulation of children with autism spectrum disorder without intellectual disability. Prior studies provided support for the reliability and criterion-related validity of the Adapted Skillstreaming Checklist total score for these children;…

This quantitative synthesis combines results of 72 studies that published psychometric information for the Multicultural Counseling Inventory. Although internal consistency, subsample means, and intrascale correlations provide promising evidence, convergent correlations with other instrumentation and factor analyses of validity continue to raise…

The study aimed to develop and validate a test for the measurement of mathematical thinking of secondary-level students. The first-stage aspects of mathematical thinking were explored for a consolidated model in line with the curriculum of secondary-level education in Pakistan. Thirty-six items were developed and piloted in three schools. Factor…

Achievement goal theory research, which investigates students' perceptions of the classroom climate, has mainly focused on teacher practices from a deductive perspective. However, this appears to hinder a fuller understanding of all the factors that influence students' perceptions of the classroom goal structures (CGS). Therefore, using a…

The assessment of environmental identity (EID) in terms of connectedness to nature, eco-friendly behaviour (EFB) and closeness to nature variables is the central focus of this study. The elaborated conceptual model recommends that closeness to nature, connectedness to nature and EFBs related to education, economy and recycling are potential…

Undergraduate science, technology, engineering, and mathematics (STEM) students' motivations have a strong influence on whether and how they will persist through challenging coursework and into STEM careers. Proper conceptualization and measurement of motivation constructs, such as students' expectancies and perceptions of value and cost (i.e.,…

The Video Engagement Scale (VES) is a quality indicator to assess engagement in experimental video-vignette studies, but its measurement properties warrant improvement. Data from previous studies were combined (N = 2676) and split into three subsamples for a stepped analytical approach. We tested construct validity, criterion validity,…

Grounded in self-expansion theory, the Senior Business Consultant Project addresses the gap between career competencies possessed by business graduates and those expected by employers. The project took place in a virtual environment to mirror future business settings. Fourth-year consulting students worked in teams of two to provide guidance to…

The study aimed to test the psychometric properties of a Portuguese adaptation of the "Adolescent Students' Basic Psychological Needs at School Scale" (ASBPNSS). For this, we used data from a sample of eighth graders (N = 1648; M[[subscript age] = 14.1 years; 46.9% girls) from Portugal. Cronbach alpha and omega coefficients showed the…

Much debate exists concerning the factorial dimensionality of student well-being. We contribute to this debate by drawing on PISA 2018 data from a total of 61,722 students, 2528 schools, and nine countries. For our investigation, we test multiple associated measurement models for convergent, discriminant, and concurrent validity, model fit, and…
