Issues and challenges in current generalizability theory applications in rated measurement
… into issues and challenges regarding the use of generalizability theory or G theory (Brennan, 2001; Cronbach, Gleser, Nanda, & Rajaratnam, 1972; Shavelson & Webb, 1991) in rated measurement given by human raters. Contexts in which such measurement prevails include, but are not limited to, …

Backcountry campsite conditions assessed for limits of acceptable change planning in Shenandoah National Park
… educational measurement are adopted, including generalizability theory and decision studies. For each indicator, these techniques reveal the consistency of raters, their ability to distinguish between unique campsites, and whether raters are systematic. These three components were found to vary …

The psychometrics of student evaluations of instructors and courses at Eastern Michigan University
<p>The study applied Classical Test Theory to the student evaluation forms for 25 departments to assess reliability. The study also applied Generalizability Theory to assess the reliability of the Psychology Department evaluation form. Regression analysis on the Psychology Department form assessed …

Dissecting implicit leadership theories: a generalizability analysis
<p>The present study uses generalizability theory to further explore the sources of variance in implicit leadership theories. Most studies which examine the differences in implicit leadership theories either focus on differences in the raters such as gender, religion, culture, and other individual …

Evaluation of a Developmentally-Based Music Therapy Tool for Children with Autism
… of the resulting ADSA scores was evaluated using generalizability theory (G-theory) statistical analysis with a fully crossed, single-facet, mixed design (r X i). The g coefficient for the ADSA tool for absolute measurement was 1.00, which surpassed the conventionally accepted reliability value of …

Generalizabiity and dependability of brief behavior rating scales for social skills
… the resulting psychometric features through generalizability theory. Data was collected in a preschool classroom in a 6 persons by 2 rater by 6-7 items by occasions mixed model design. Data was analyzed series of generalizability and decision studies to investigate sources of variability and …

Generalizability of Center of Pressure Measurements Across Age Populations
… multiple age populations (Study 3). The tools of Generalizability Theory (G-Theory) were used to thoroughly examine the reliability of both summary and time-varying measurements of COP. G-Theory is a powerful reliability analysis tool that permits the systematic inspection of identified components …

Analysis of the Psychometric Properties of Two Different Concept-Map Assessment Tasks
… design. This design made it possible to use generalizability theory to identify and estimate the variance in the ratings contributed by the three factors mentioned, the interaction effects, and unexplained error. The criterion validity of the concept-map ratings was examined by computing …

Quantifying the Reliability of Performance Time and User Perceptions Obtained from Passive Exoskeleton Evaluations
… a more advanced statistical approach (i.e., Generalizability Theory), while also identifying potential effects of EXO type, work task, and individual differences. This work used data from a recently completed EXO evaluation study, conducted in Virginia Tech's Occupational Ergonomics and …

Use of Technology for Physical Activity Assessments and Intervention Applications
… intraclass correlation coefficients > 0.93). Generalizability theory coefficients showed lower values for the running speed (0.70) versus the walking speeds (all > 0.84) with the majority of the variability derived from the participant (68% - 88%). Acceptable validity was found overall …

Preliminary psychometric characteristics of the critical thinking self-assessment scale
… of the scale was based on Cronbach’s Generalizability theory, and used Messick’s (1990) unitary concept of construct validity framework for evaluating the psychometric properties of the scale. The researcher developed 196 peer reviewed items for the Critical Thinking Self Assessment …
