Tülin Otbiçer Acar – Measurement: Interdisciplinary Research and Perspectives, 2024
The aim of this study is to compare the results of correlation coefficient estimation of reliability with those obtained through the Bland-Altman plot technique. The scale was first divided into two halves using three different approaches. A linear and high-level relationship was found between the scale scores obtained from the halved forms.…

Viola Merhof; Caroline M. Böhm; Thorsten Meiser – Educational and Psychological Measurement, 2024
Item response tree (IRTree) models are a flexible framework to control self-reported trait measurements for response styles. To this end, IRTree models decompose the responses to rating items into sub-decisions, which are assumed to be made on the basis of either the trait being measured or a response style, whereby the effects of such person…

Lee, Minji K.; Sweeney, Kevin; Melican, Gerald J. – Educational Assessment, 2017
This study investigates the relationships among factor correlations, inter-item correlations, and the reliability estimates of subscores, providing a guideline with respect to psychometric properties of useful subscores. In addition, it compares subscore estimation methods with respect to reliability and distinctness. The subscore estimation…

Lowe, Patricia A. – Journal of Psychoeducational Assessment, 2018
The psychometric properties of a new, multidimensional measure of test anxiety, the Test Anxiety Measure for College Students (TAM-C), were examined in a sample of 720 undergraduate students. Results of confirmatory factor analyses provided support for a six-factor (Cognitive Interference, Physiological Hyperarousal, Social Concerns,…

Wong, Venus; Ruble, Lisa A.; McGrew, John H.; Yu, Yue – School Psychology Quarterly, 2018
Consultation is essential to the daily practice of school psychologists (National Association of School Psychologist, 2010). Successful consultation requires fidelity at both the consultant (implementation) and consultee (intervention) levels. We applied a multidimensional, multilevel conception of fidelity (Dunst, Trivette, & Raab, 2013) to a…

Costa, Sebastiano; Ingoglia, Sonia; Inguglia, Cristiano; Liga, Francesca; Lo Coco, Alida; Larcan, Rosalba – Measurement and Evaluation in Counseling and Development, 2018
The purpose of this multistudy report was to adapt the Basic Psychological Need Satisfaction and Frustration Scale (BPNSFS) to the Italian context. Two studies were conducted. In Study 1, we investigated the dimensionality, reliability, and convergent and discriminant validity of the instrument in a sample of 544 participants (males = 41%) from 16…

Turner, Michelle; Holdsworth, Sarah; Scott-Young, Christina M. – Higher Education Research and Development, 2017
While measures of resilience have been applied in university settings, progress has been hindered by the lack of a consistent measure of resilience. Additionally, results from these measures cannot be easily translated into practical curriculum-based initiatives which support resilience development. Resilience is linked to student mental health…

Mazer, Joseph P.; Thompson, Blair – Communication Education, 2016
This study offers validity evidence for the Parental Academic Support Scale, a 16-item multidimensional measure that assesses support related to a child's academic performance, classroom behavior, preparation, hostile peer interactions, and health. Confirmatory factor analysis of the Parental Academic Support Scale (PASS) revealed a close model…

OECD Publishing (NJ1), 2009
The Organisation for Economic Cooperation and Development's (OECD's) Programme for International Student Assessment (PISA) surveys, which take place every three years, have been designed to collect information about 15-year-old students in participating countries. PISA examines how well students are prepared to meet the challenges of the future,…

Landgraf, Jeanne M. – Journal of Attention Disorders, 2007
Objective: To develop and evaluate a questionnaire, the ADHD Impact Module for Adults (AIM-A), to dimension quality of life for adults with attention-deficit/hyperactivity disorder (ADHD). Method: Six multi-item AIM scales were developed and evaluated in 317 participants enrolled in an open-label trial. Multitrait scaling analysis and correlations…

Korpi, Meg; Haertel, Edward – 1984
The purpose of this paper is to further the cause of clarifying construct interpretations of tests, by proposing that non-metric multidimensional scaling may be more useful than factor analysis or other latent structure models for investigating the internal structure of tests. It also suggests that typical problems associated with scaling…

Huebner, E. Scott – Psychological Assessment, 1994
Two studies involving 725 elementary school students describe the development and preliminary validation of a measure of children's life satisfaction, the Multidimensional Students' Life Satisfaction Scale. For the most part, the measure's subscales correlate as expected with various criterion measures. The instrument appears useful for research…

Knapp-Lee, Lisa; Michael, William B. – Educational and Psychological Measurement, 1983
This study (1) provided evidence concerning the construct validity of scales based on the clusters found in a revised, professional-level form of the California Occupational Preference System Interest Inventory and (2) examined the degree of internal consistency of the 16 newly devised subscales.

Hendrickson, Gerry F.; Green, Bert F., Jr. – 1972
It has been shown that Guttman weighting of test options results in marked increases in the internal consistency of a test. However, the effect of this type of weighting on the structure of the test is not known. Hence, the purpose of this study is to compare the factor structure of Guttman-weighted and rights-only-weighted tests and to relate the…
