The London Measure of Unplanned Pregnancy (LMUP)                  

This website provides information about the London Measure of Unplanned Pregnancy (LMUP), a psychometrically-validated measure of pregnancy planning/intention developed by Geraldine Barrett and colleagues. Originally developed in the UK, the LMUP has now been validated for use in countries across all five continents. The main publications are from 2002 onwards. Technical information about the LMUP is provided on this website (essentially ‘the LMUP handbook’) and is continually updated.
