The London Measure of Unplanned Pregnancy (LMUP)            

Development Study
The study to develop and evaluate the London Measure of Unplanned Pregnancy began in October 1998, funded by the UK Medical Research Council via a special training fellowship in health services research awarded to Geraldine Barrett. The study formed the basis of Geraldine Barrett's PhD which was awarded in 2002. The study involved the participation and support of a large number of people.
