This paper examines one of three central diagnostic tools of the Concerns Based Adoption Model, the Stages of Concern Questionnaire (SoCQ). The SoCQ was developed with a focus on K12 education. It has been used widely since developed in 1973, in early childhood, higher education, medical, business, community, and military settings. The SoCQ…

Despite several psychometric advantages over the 50-item Autism Spectrum Quotient, an instrument used to measure autistic traits, the abridged AQ-28 and its cross-cultural validity have not been examined as extensively. Therefore, this study aimed to examine the factor structure and measurement invariance of the AQ-28 in 818 Dutch (M[subscript…

Assessment of functional impairment provides information that is complementary to diagnostic criteria information and is critical for identifying targets for intervention and evaluating treatment outcomes. This review presents summative psychometric information for five multidimensional measures of functional impairment developed for use with…

Originally designed for students in Grades 3 through 5, MOCCA (formerly the Multiple-choice Online Causal Comprehension Assessment), identifies students who struggle with comprehension, and helps uncover why they struggle. There are many reasons why students might not comprehend what they read. They may struggle with decoding, or reading words…

The present study examined the measurement properties of the Emotional and Behavioral Screener (EBS), a universal screening instrument which identifies students presenting with emotional and behavioral problems. The primary research questions sought to examine the degree to which the EBS item responses fit the Rasch model through evaluating fit of…

The main purpose of this study was to conduct a validation analysis of student surveys of teaching effectiveness implemented at Bangkok University, Thailand. This study included three phases; survey development, a pilot study, and a full implementation study. Four sources of validity evidence were collected to support intended interpretations and…

Reading comprehension is often treated as a multidimensional construct. In many reading tests, items are distributed over reading process categories to represent the subskills expected to constitute comprehension. This study explores (a) the extent to which specified subskills of reading comprehension tests are conceptually conceivable to…

"The Woodcock-Johnson IV Tests of Cognitive Abilities" (WJ IV COG) is an individually administered measure of psychometric intellectual abilities designed for ages 2 to 90+. The measure was published by Houghton Mifflin Harcourt-Riverside in 2014. Frederick Shrank, Kevin McGrew, and Nancy Mather are the authors. Richard Woodcock, the…

Preparing and supporting teachers to enact teaching practice that responds to diversity, challenges educational inequities, and promotes social justice is a pressing yet daunting and complex task. More research is needed to understand how and to what extent teacher education programs prepare and support teacher candidates to enhance the…

In almost all high-stakes testing programs, test equating is necessary to ensure that test scores across multiple test administrations are equivalent and can be used interchangeably. Test equating becomes even more challenging in mixed-format tests, such as Advanced Placement Program® (AP®) Exams, that contain both multiple-choice and constructed…

Views on testing--its purpose and uses and how its data are analyzed--are related to one's perspective on test takers. Test takers can be viewed as learners, examinees, or contestants. I briefly discuss the perspective of test takers as learners. I maintain that much of psychometrics views test takers as examinees. I discuss test takers as a…

Educational achievement is a very important issue for parents, teachers, and the government. An accurate measurement plays a very important role in evaluating achievement fairly, and, therefore, analysis methods have been developed considerably in recent years. Education based on long-time learning processes forms a fruitful base for item tests,…

The Gilliam Autism Rating Scale-Second Edition (GARS-2) is a screening tool for autism spectrum disorders for individuals between the ages of 3 and 22. It was designed to help differentiate those with autism from those with severe behavioral disorders as well as from those who are typically developing. It is a norm-referenced instrument that…

Confusion in the literature between the concepts of internal consistency and homogeneity has led to a misuse of coefficient alpha as an index of item homogeneity. This misuse is discussed and several indices of item homogeneity derived from the model of common factor analysis are offered as alternatives. (Author/JKS)

Hoyt's analysis of variance procedure for estimating reliability assumes that the residual mean square estimates error variability. If, however, an individual's true score varies across items, it is argued that residual mean square estimates two components--error and interaction--and hence Winer's modification of Hoyt's formula, understimates the…
