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…

Background: Research about the psychometric properties of the Behavioural Appraisal Scales (BAS) in people with profound intellectual and multiple disabilities (PIMD) is limited. This study evaluates invariance in factor structure, item bias and convergent validity of the BAS. Methods: Data on the BAS from two studies (n = 25; n = 52) were…

Growing interest in interdisciplinary (ID) understanding has led to the recent development of four ID assessments, none of which have previously been comprehensively validated. Sources of evidence for the validity of tests include construct validity, such as the internal structure of the test. ID tests may (and should) test both disciplinary (D)…

This study reports an independent investigation of the psychometric properties of Desired Results Developmental Profile (DRDP), a teacher-rated measure of school readiness for preschool-aged children. In a sample of 2,031 low-income, 3- to 5-year-old children attending Head Start, we tested three measurement models: a higher order one-factor…

The New Mexico Public Education Department developed the Kindergarten Observation Tool (KOT) as a multidimensional observational measure of students' knowledge and skills at kindergarten entry. The primary purpose of the KOT is to inform instruction, so that kindergarten teachers can use the information about their students' knowledge and skills…

The State of Washington requires school districts to file court petitions on students with excessive unexcused absences. The "Washington Assessment of Risks and Needs of Students" (WARNS), a self-report screening instrument developed for use by high school and juvenile court personnel in such situations, purports to measure six facets of…

This study reports an independent investigation of the psychometric properties of Desired Results Developmental Profile (DRDP), a teacher-rated measure of school readiness for preschool-aged children. In a sample of 2,031 low-income, 3- to 5-year-old children attending Head Start, we tested three measurement models: a higher order one-factor…

The conceptual foundation and initial psychometric evidence are provided for the "Instructional Coaching Rating Scales" and "Interaction Style Scales--Teacher Forms." These forms are part of a multicomponent online assessment system designed to evaluate the effectiveness of coaching skills and interactions that support the…

This article presents information about the construct validity and reliability of a new teacher self-report measure of classroom instructional and behavioral practices (the Classroom Strategies Scales-Teacher Form; CSS-T). The theoretical underpinnings and empirical basis for the instructional and behavioral management scales are presented.…

The objective of this study was to examine the construct validity and bias of a child health interview (CHI) instrument to assess young children's food and activity preferences. A quantitative study examining the construct validity and bias of a young child health interview instrument using confirmatory factor analysis (CFA) and multi-group CFA…

The psychometric properties of a 10-item math motivation scale were empirically validated with an independent sample consisting of 182 elementary-school students. Analysis of the model dimensionality supported a one-factor structure fit. Item parameter estimates from a Classical Test Theory framework revealed that most items were highly…

Purpose: The answer-copying tendency has the potential to detect suspicious answer patterns for prior distributions of statistical detection techniques. The aim of this study is to develop a valid and reliable measurement tool as a scale in order to observe the tendency of university students' copying of answers. Also, it is aimed to provide…

Research on progress monitoring has almost exclusively focused on student behavior and not on teacher practices. This article presents the development and validation of a new teacher observational assessment (Classroom Strategies Scale) of classroom instructional and behavioral management practices. The theoretical underpinnings and empirical…

Student participation in undergraduate research (ugr) may be influenced by interest in research, future career and educational plans, perceived value of undergraduate research experiences, or perceived competence in research skills. The purpose of this study was to develop a questionnaire that could be used to validly and reliably assess students'…

Many psychological scales written in the Likert format include reverse worded (RW) items in order to control acquiescence bias. However, studies have shown that RW items often contaminate the factor structure of the scale by creating one or more method factors. The present study examines an alternative scale format, called the Expanded format,…
