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 the world. 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.


New evaluation

An evaluation of the LMUP in Australia has been published:

Lang AY, Hall JA, Harrison CL, Teede H, Moran LJ, Barrett G. 2019 Validation of the London Measure of Unplanned Pregnancy among pregnant Australian women PLoS ONE 14(8): e0220774 Abstract and full text

Reliability of the LMUP

There are two NEW studies looking at the reliability of the LMUP in terms of its stability over time. Both show the LMUP to have good reliability.

The first paper shows that the LMUP performs better than the Demographic and Health Survey question on pregnancy intention:

Hall JA, Stephenson J, Barrett G. 2019 On the stability of reported pregnancy intentions from pregnancy to 1 year postnatally: impact of choice of measure, timing of assessment, women's characteristics and outcome of pregnancy. Maternal and Child Health Journal Online first Abstract and full pdf

The second paper shows that the LMUP has good reliability among women who sought abortion:

Rocca CH, Wilson MR, Jeon M, Foster DG. 2019 Stability of retrospective pregnancy intention reporting among women with unwanted pregnancies in the United States Maternal and Child Health Journal Online first Abstract

New recommendation to use the LMUP

The LMUP is recommended for use in relation to preconception care in the UK:

Stephenson J, Vogel C, Hall J, Hutchinson J, Mann S, Duncan H, Woods-Townsend K, de Lusignan S, Poston L, Cade J, Godfrey K, Hanson M, Barrett G, Barker M, Conti G, Shannon G, Colbourn T, for the Preconception Partnership. 2019 Preconception health in England: a proposal for annual reporting with core metrics. Lancet 393(10187): 2262-2271. doi:10.1016/S0140-6736(19)30954-7 Abstract
