An Item Response Theory Analysis Of Emotional Expressivity Measures, Melissa K. Matheys
An Item Response Theory Analysis Of Emotional Expressivity Measures, Melissa K. Matheys
Theses and Dissertations
The understanding of psychometric properties of emotional expressivity measures is often limited to rudimentary statistics. The present study investigated, in depth, the psychometric properties of four measures of emotional expressivity (the Self-Concealment Scale, the Distress Disclosure Index, the Emotional Expressivity Scale, and the Emotion Regulation Questionnaire – Suppression subscale). Item response theory (IRT) analyses suggested that recoded versions of the measures’ Likert scales may be beneficial in practice as well as the deletion of some measures’ items. IRT analyses of the four measures of emotional expressivity provide more information than classical test theory statistics about how to implement these measures …

The Effects Of Scaling On Trends Of Development: Classical Test Theory And Item Response Theory, Weldon Z. Smith
College of Education and Human Sciences: Dissertations, Theses, and Student Research
The scale metrics used in educational testing are often arbitrary, and this can impact interpretation of scores on measurements. Both classical test theory sum scores and item response theory estimates measure the same underlying dimension, but differences in the two scales may lead one to be more preferential than the other in interpreting data. Mismatch between individual ability and test difficulty can further result in difficulties in correctly interpreting trends of development in longitudinal data. A previous limited simulation by Embretson (2007) demonstrated that classical test theory sum scores result in misinterpretation of linear trends of development, and that item …
