Abstract

New ways of measuring pregnancy planning/intention such as the London Measure of Unplanned Pregnancy (LMUP), which recognise the complexity of the construct, are being adopted worldwide. The aim of this study was to evaluate the psychometric properties of the Krio version of the LMUP in Sierra Leone. An interviewer-administered version of the LMUP was translated into Krio and pre-tested with 12 pregnant women. Field testing involved 172 pregnant women aged 15–42, with 87 completing a re-test. Completion rates of LMUP items were 100%. LMUP scores 1-12 were captured. Reliability: the scale was internally consistent (Cronbach‘s alpha 0.84) and stable (weighted Kappa 0.93). Construct validity: all hypotheses were confirmed. Principal components analysis revealed five items (items 2-6) related to one construct. Mokken scaling procedure selected the same five items. Removal of item 1 (which had 97% endorsement of the ‗no contraception‘ response option) brought about only a very slight improvement in LMUP performance, therefore we recommend retaining all six items. The Krio LMUP is reliable, valid and suitable to use in Sierra Leone. (Afr J Reprod Health 2019; 23[4]:81-91).
