We evaluated the psychometric properties of the London Measure of Unplanned Pregnancy among Indian women using classical methods and Item Response Modeling. The scale exhibited good internal consistency and internal structure, with overall scores correlating well with each item’s response categories. Items performed similarly for pregnant and non-pregnant women, and scores decreased with increasing parity, providing evidence for validity. Analyses detected small disadvantages, including low endorsement of middle response categories and some evidence of differential item functioning by parity. We conclude that the LMUP is suitable for use in India and recommend steps for improving scale performance for this cultural context.
