Despite agreement about the central importance of validity for educational and psychological testing, consensus regarding the definition of validity remains elusive. Differences in the definition of validity are examined and reveals that a potential cause of disagreement stems from differences in word use and meanings given to key terms commonly…

As the research on feigning has grown, the number and quality of performance validity tests (PVTs) has increased as well. However, while several PVTs have been developed from assessments commonly used as part of neuropsychological batteries, there has been less exploration for PVTs scored from items in cognitive screeners. The Montreal Cognitive…

Psychometric characteristics of CESD-R scores were explored on a sample of 966 undergraduate students. Internal consistency ([alpha] = 0.92), external convergent and discriminant validity, and response bias were adequate to excellent. Strong measurement invariance was evident for gender and race comparisons, and the unidimensional model fit the…

Aberrant behavior refers to any type of unusual behavior that would not be expected under normal circumstances. In educational and psychological testing, such behaviors have the potential to severely bias the aberrant examinee's test score while also jeopardizing the test scores of countless others. It is therefore crucial that aberrant examinees…

This dissertation aims to bridge the gap between validity theory and the practice of validation. The dissertation employs a three-article approach. Following the introduction in Chapter I, three independent manuscripts representing three empirical studies are presented (i.e., Chapters II - IV). Each chapter is a stand-alone publishable manuscript,…

In recent years, some models for binary and graded format responses have been proposed to assess unipolar variables or "quasi-traits." These studies have mainly focused on clinical variables that have traditionally been treated as bipolar traits. In the present study, we have made a proposal for unipolar traits measured with continuous…

The purpose of this study is to examine how validity has been presented in technical and other users' manuals for various editions (i.e., revisions) of the same commercially published test over time. Although the unitary view of validity came to prominence more than 30 years ago and has been embraced in the "Standards for Educational and…

Quality assessment is an essential component of preschool education. The Standards for Educational and Psychological Testing provide benchmarks for evaluating the validity of inferences made from assessment or test results (AERA, APA & NCME, 2014). According to the Standards, test developers should investigate and document information related…

The "Standards for Educational and Psychological Testing" have served as a cornerstone for best practices in assessment. As the field evolves, so must these standards, with regular revisions ensuring they reflect current knowledge and practice. The National Council on Measurement in Education (NCME) conducted a survey to gather feedback…

One of the substantive changes in the 2014 Standards for Educational and Psychological Testing was the elevation of fairness in testing as a foundational element of practice in addition to validity and reliability. Previous research indicates that testing practices often do not align with professional standards and guidelines. Therefore, to raise…

This study contributes to validity studies by determining the cut-off point of an inventory measuring university students' anxiety levels with Angoff, ROC, and Borderline methods and by examining high/low anxiety levels according to these methods point. The study is regarded as a basic research due to the newly-added data in a multi-scoring…

Purpose: Children with (central) auditory processing disorder [(C)APD] exhibit many cognitive difficulties and receive negative psychosocial consequences from their disorder. Diagnosis of (C)APD relies on multidisciplinary assessment, including psychological testing. There is a strong need for valid and reliable questionnaires to identify children…

This technical report documents the processes and procedures implemented to support the Spring 2021 Nebraska Student-Centered Assessment System (NSCAS) Phase I Pilot in English Language Arts (ELA), Mathematics, and Science assessments by NWEA® under the supervision of the Nebraska Department of Education (NDE). The technical report shows how the…

This study reports the evaluation of four positive psychology assessments for use in clinical, education, and research settings with individuals in Ghana, Africa. The analyses attempted to identify validity evidence for internal structure and relationships with related variables for the Satisfaction with Life Scale (SLS; Diener et al.…

In Winter 2021-2022, the Nebraska Student-Centered Assessment System (NSCAS) assessments are administered in ELA and mathematics in Grades 3-8. In Spring 2021-2022, the NSCAS assessments are administered in English language arts (ELA) and mathematics in Grades 3-8 and in science in Grades 5 and 8. The purposes of the NSCAS assessments are to…
