Introduction to Rasch Analysis

A workshop to introduce Rasch analysis. It will suit those working in the measurement of outcomes in the health sciences, of attitudinal data in the social sciences, or in educational testing. It will take the form of hands-on tuition in using the Rasch Unidimensional Measurement Models ( RUMM2020 ) software package. At the end of the two-and-a-half days workshop students should understand and be able to analyse data, using RUMM2020, for:

Internal construct validity (Unidimensionality);
Category probability patterns for polytomous items;
Differential Item Functioning;
Scaling Characteristic

Rasch Refresher Day

For those who do not get enough practice at Rasch analysis as they would like, or where some time has passed since they undertook the introductory course. The aim of this one day workshop is to ensure participants are working to the latest protocol using the Rasch Unidimensional Measurement Models ( RUMM2020 ) software package. It will also provide the opportunity to practice while faculty are available to help. It will take the form of a morning update of the analytical process, and an afternnon practice with own data. Topics to be cobvered include:

Local dependence assumptions ;
Use of testlets to absorb local response dependency;
Use of testlets to see if Differential Item Functioning cancels out;
Current issues in unidimensionality testing

Intermediate Rasch Analysis.

This workshop will look at more advance topics using the RUMM2020 software, and will include issues of pooling data from international studies, establishing item banks, Computer Adaptive Testing and writing a Rasch paper. Students should have completed the introductory course, or have experience with RUMM 2020 software.

At the end of this workshop, students should be able to:

Adjust estimates of patient ability (or trait) for cross-cultural differences in outcome measures (to facilitate pooled data in international studies).
Conduct multi-faceted Rasch analysis
Comparison with WINSTEPS
Establish an item bank
Use the item bank to inform and use Computer Adaptive Testing software (currently we use FastTEST pro)
Write a good Rasch paper

Advanced Rasch Analysis.

This workshop will concentrate on introducing substantive methodological issues using a range of software, and will include simulation of data to address a current issue of methodological concern.

At the end of this workshop, students should be able to:

Stimulate data to examine the effect of multidimentionality, DIF and other factors on person estimates

Address issues such as the robustness of estimates to the presence of DIF
