A. Introduction to Rasch analysis.
May 15th-17th  2002.
September 18th-20th 2002.
December 11th-13th 2002.
May 14th-16th 2003.
An introductory workshop to introduce Rasch analysis and Item Response
Theory to those working in outcome measurement in health and social
sciences. The workshop will take the form of hands-on tuition in using the
Rasch Unidimensional Measurement Models (RUMM) software package. At the end
of the two-and-a-half days workshop students should understand and be able
to analyse data, using RUMM, for:
·       Internal construct validity (Unidimensionality);
·       Category probability patterns for polytomous items;
·       Differential Item Functioning;
·       Scaling Characteristics.
Fee £600 inclusive of two nights accommodation and breakfast.

B. Intermediate Rasch analysis.
May 20th-22nd  2002.
September 23rd-25th 2002.
May 19th-21st 2003.
This workshop will look at more advance topics using the RUMM software, and
will include issues of pooling data from international studies
(Differential Item Functioning analysis); detailed tuition on multi-faceted
Rasch analysis (adjusting for rater severity) and accounting for
interviewer bias in surveys where questionnaires are embedded within the
interview.
At the end of this workshop, students should be able to:
·       Adjust the results of tests for rater severity.
·       Adjust estimates of patient ability (or trait) for cross-cultural
differences in outcome measures (to facilitate pooled data in international
studies).
·       Adjust the results of social and health surveys for interviewer
bias. 
Fee £1000 inclusive of two nights accommodation and breakfast.

C. An introduction to Unfolding models for preference and choice.
May 22nd -23rd 2003.
A two-day workshop to introduce unfolding models in the form of hands-on
tuition using the RateFOLD2001 software package. At the end of the two-day
workshop students should have an understanding of:
·       Data structures for preference and choice analysis
·       The hyperbolic cosine model
·       Interval level scaling for health economics and marketing analysis
Fee £800 inclusive of two nights accommodation and breakfast.

Distance learning courses on the underlying theory of measurement are also
available.
