THE TENTH INTERNATIONAL WORKSHOP ON
METHODOLOGY OF TWIN AND FAMILY STUDIES:
THE INTRODUCTORY COURSE

After their inauguration in July, 1987, in Leuven, Belgium, these workshops have been held twice more in Leuven, once in Helsinki, and five times at the Institute for Behavioral Genetics, Boulder, Colorado. Each has been tremendously successful (and oversubscribed). Papers resulting from the inaugural workshop were published in a Special Issue of Behavior Genetics: Twin methodology using LISREL, 19(1), 1989. The course material from the previous workshops has now been published as a methodology handbook by Neale, M. C., Cardon, L. R., & 11 contributing authors as Methodology for Genetic Studies of Twins and Families, Dordrecht, The Netherlands: Kluwer Academic Press, 1992.

The next workshop will be held again in Boulder, Colorado, the first week of March 1998, with David Fulker and John Hewitt as local hosts. The application programming will be based on the package, Mx, developed by Dr. Mike Neale for the flexible analysis of genetically-informative data. The Mx home page is at http://griffin.vcu.edu/mx.

This course is intended to be introductory. Participants interested in more advanced work (e.g., those who have attended earlier workshops) should consider attending the advanced workshops planned for 1999, 2001, and 2003 (if funding requests are successful) in Boulder, or September 1998 in Leuven. (For information about the Leuven workshop contact hmaes@ruby.vcu.edu or martine.thomis@flok.kuleuven.ac.be)

The registration fee will be $300.00, payable by January 10, 1998. Accommodations are being reserved at the Regal Harvest House, Boulder.
