The London Measure of Unplanned Pregnancy (LMUP)                

Evaluation of the LMUP in Australia
Dr Adina Lang of Monash Centre for Health Research and Implementation (MCHRI), Monash University led the psychometric validation of the LMUP in Australia. The validation was conducted by Dr Lang as part of her PhD research exploring pregnancy intentions, preparations and preconception health behaviours of Australian women. The validation was completed in collaboration with Dr Geraldine Barrett (original developer of the LMUP) and Dr Jennifer Hall (University College London) with supervision from Associate Professor Jacqueline Boyle, Dr Cheryce Harrison and Associate Professor Lisa Moran of Monash Centre for Health Research and Implementation, Monash University, Australia.

Following a process of adaptation and cognitive testing, the Australian LMUP was field tested with 317 pregnant women of reproductive age (18-44 years). These women were recruited through public and private Australian maternity care systems and self-completed the questionnaire online or in hard copy (August 2017 to March 2018). A subset of 131 women completed the Australian LMUP a second time (test-retest component) approximately 2 weeks later. The evaluation of the LMUP was embedded within a broader cross-sectional questionnaire which, in addition to the six LMUP questions, collected basic socio-demographic information and details of women's pregnancy preparation behaviours.

The LMUP's psychometric properties were evaluated using Classical Test Theory analyses to assess the tools acceptability, reliability, stability and validity. The validation confirmed the Australian LMUP to be a valid and reliable measure of pregnancy planning and intention for the Australian population and can be downloaded for future use in Australia. The scoring method is the same as the original LMUP. Full details are available in the published paper:
