School personnel make a variety of decisions within multitiered problem-solving frameworks, including the decision to assign a student to group-based support, to design an individualized support plan, or classify a student as eligible for special education. Each decision is founded upon a judgment regarding whether the student has responded to…

Of particular import to this study, is collider bias originating from stratification on retreatment variables forming an embedded M or bowtie structural design. That is, rather than assume an M structural design which suggests that "X" is a collider but not a confounder, the authors adopt what they consider to be a more reasonable…

Taxometric analyses have proven helpful for distinguishing categorical and dimensional data. Many taxometric procedures require at least 3 variables for analysis. What if a construct is defined by only 2 conceptually nonredundant characteristics or a data set contains only 2 empirically nonredundant variables? In Study 1, we performed extensive…

The authors aimed to propose a valid and reliable diagnostic instrument by developing a three-tier test on simple electric circuits. Based on findings from the interviews, open-ended questions, and the related literature, the test was developed and administered to 124 high school students. In addition to some qualitative techniques for…

In this article we examine the factorial structure of the Greek version of the Zimbardo Time Perspective Inventory (ZTPI; Zimbardo and Boyd in "J Personal Soc Psychol" 77:1271-1288, 1999), in a sample of 337 university students, using principal axis factoring (PAF) with oblique rotation, and its dimensionality using parallel analysis.…

Background: This study describes the development and trialling of the Family Life Interview (FLI), a clinical tool designed to examine sustainability of family routines. Materials and Methods: The FLI, a self-report instrument completed by a parent within a semi-structured practitioner--parent interview, was administered to 118 parents, with…

In an era of evidence-based practice, why are clinicians not typically engaged in evidence-based assessment? To begin to understand this issue, a national multidisciplinary survey was conducted to examine clinician attitudes toward standardized assessment tools. There were 1,442 child clinicians who provided opinions about the psychometric…

Extended time is one of the most common testing accommodations provided to students with disabilities. It is also controversial; critics of extended time accommodations argue that extended time is used too readily, without concern for how it changes the skills measured by tests, leading to scores that cannot be compared fairly with those of other…

Methods of incorporating a ridge type of regularization into partial redundancy analysis (PRA), constrained redundancy analysis (CRA), and partial and constrained redundancy analysis (PCRA) were discussed. The usefulness of ridge estimation in reducing mean square error (MSE) has been recognized in multiple regression analysis for some time,…

Receptive foreign language proficiency is usually measured with reading and listening comprehension tasks. A novel approach to assess such proficiencies--viewing comprehension--is based on the presentation of short instructional videos followed by one or more comprehension questions concerning the preceding video stimulus. In order to evaluate a…

A theoretical variable such as integrity, conscientiousness, or academic honesty may correspond to either a construct or a concept, but the standard idiom does not distinguish the two. One can describe the difference between constructs and concepts in terms of set theory. Constructs extend over actual cases, whereas concepts extend over both…

The purpose of the present study was to highlight the importance of acculturation as an explanatory variable in career development and to provide an empirical review of acculturation research in the career development literature. Acculturation is a cultural variable that has been linked to a number of important career development outcomes for…

We administered two instruments designed to assess and predict teacher effectiveness, the TeacherInsight Interview (TI) and the Renaissance Teacher Work Sample (TWS), to student teachers (N = 396) at a large comprehensive institution in the Southeastern United States to investigate whether TWS performance predicts TI scores. We first investigated…

The objective of this study was to investigate the contribution of rapid digit naming, phonological memory, letter sound naming, and orthographic knowledge to the prediction of responsiveness to a school-based, individual intervention of word reading fluency problems of 122 Dutch second and third graders whose reading scores were below the 10th…

This study describes the reliability reporting practices in empirical studies using eight adolescent alcohol screening tools and characterizes and explores variability in internal consistency estimates across samples. Of 119 observed administrations of these instruments, 40 (34%) reported usable reliability information. The Personal Experience…
