目的：评价伦敦非计划妊娠量表（一种英国-开发的措施怀孕的意图），在英语和西班牙语翻译，在美国人口的women.Methods：一个心理测量评估研究的伦敦措施计划外怀孕（LMUP），六项，自我完成的纸措施进行了346名妇女，年龄在15-45谁提出到旧金山弗朗西斯科总医院终止妊娠或产前护理。对两种语文文本的分析是分别进行的。可靠性（内部一致性）进行了评估，使用Cronbach的α和项目总相关。使用加权Kappa评估重测信度（稳定性）。结构效度采用主成分分析和假设检验进行评估。心理测量学测试表明，LMUP在美国和英国都是可靠和有效的（α = 0.78，所有项目-总相关性>0.20，加权Kappa = 0.72，证实了单维性，满足假设）和西班牙语翻译（α = 0.84，所有项目-总相关>0.20，加权Kappa = 0.77，单维度确认，满足假设）。结论：LMUP在美国英语和西班牙语翻译中是可靠和有效的，因此现在可以用于美国妇女。
Objective: To evaluate the reliability and validity of the London Measure of Unplanned Pregnancy (a U.K.-developed measure of pregnancy intention), in English and Spanish translation, in a U.S. population of women.Methods: A psychometric evaluation study of the London Measure of Unplanned Pregnancy (LMUP), a six-item, self-completion paper measure was conducted with 346 women aged 15-45 who presented to San Francisco General Hospital for termination of pregnancy or antenatal care. Analyses of the two language versions were carried out separately. Reliability (internal consistency) was assessed using Cronbach's alpha and item-total correlations. Test-retest reliability (stability) was assessed using weighted Kappa. Construct validity was assessed using principal components analysis and hypothesis testing.Results: Psychometric testing demonstrated that the LMUP was reliable and valid in both U.S. English (alpha = 0.78, all item-total correlations >0.20, weighted Kappa = 0.72, unidimensionality confirmed, hypotheses met) and Spanish translation (alpha = 0.84, all item-total correlations >0.20, weighted Kappa = 0.77, unidimensionality confirmed, hypotheses met).Conclusion: The LMUP was reliable and valid in U.S. English and Spanish translation and therefore may now be used with U.S. women.
