Mixed Rasch Models for Measurement in Cognitive Psychology
2007To apply standard unidimensional IRT models to ability measurement, it must be assumed that individuals at the same level of performance are in fact comparable. That is, individuals with the same estimate on the latent trait are interchangeable and thus can have identical interpretations given to their scores. Such interpretations, of course, depend on

Sequential Analysis of Quality-of-Life Measurements Using Mixed Rasch Models
2008Early stopping of clinical trials in the case of either beneficial or deleterious effect of a treatment on quality of life (QoL) is an important issue. QoL is usually evaluated using self-assessment questionnaires and responses to the items are usually combined into QoL scores assumed to be normally distributed.

Applying the Mixed Rasch Model to the Runco Ideational Behavior Scale
Creativity Research Journal, 2016Previous research using creativity assessments has used latent class models and identified multiple classes (a 3-class solution) associated with various domains. This study explored the latent class structure of the Runco Ideational Behavior Scale, which was designed to quantify ideational capacity.

Individual differences in response scale use: Mixed Rasch modelling of responses to NEO-FFI items
Personality and Individual Differences, 2006Mixed Rasch modelling allows the existence of sub-groups who differ in their use of questionnaire response scales to be investigated. This is relevant to personality measurement, as individual differences in scale use are a source of error in calculating trait scores. The objectives of the analysis reported here were to investigate the use of the mixed

Journal of Clinical Epidemiology, 2007
This study published in two companion papers assesses properties of the Mini-Mental State Examination (MMSE) with the purpose of improving the efficiencies of the methods of screening for cognitive impairment and dementia.An item analysis by conventional and mixed Rasch models was used to explore empirically derived cognitive dimensions of the MMSE, to

Journal of Mixed Methods Research, 2016
Developing psychometrically sound instruments can be difficult, especially if little is known about the constructs of interest. When constructs of interest are unclear, a mixed methods approach can be useful. Qualitative inquiry can be used to explore a construct’s meaning in a way that informs item writing and allows the strengths of one analysis ...

Introducing Emotioncy as a Potential Source of Test Bias: A Mixed Rasch Modeling Study
International Journal of Testing, 2016This article attempts to present emotioncy as a potential source of test bias to inform the analysis of test item performance. Emotioncy is defined as a hierarchy, ranging from exvolvement (auditory, visual, and kinesthetic) to involvement (inner and arch), to emphasize the emotions evoked by the senses.

Mixture IRT models such as the mixed Rasch model (RM) have the potential to illuminate conflicting findings in the analysis of responses to organizational assessments of noncognitive abilities such as personality inventories and attitude assessments. The preponderance of psychometric work (especially in the early history of test analysis) has been done

Determination of Diagnostic Cut-Points Using Stochastically Ordered Mixed Rasch Models
2007Diagnostic tests aim to discriminate between clinically normal and clinically abnormal cases. When raw scores summarizing responses to items in psychiatric or health related scales are used for diagnostic purposes, it is required that measurements are both valid and reliable.
