研究目的：开发一种在当代人口趋势和社会风俗背景下有效、可靠和适当的意外怀孕测量方法，并可用于各种情况，包括人口患病率估计。设计：两阶段研究设计：定性(归纳)方法描述怀孕计划的结构，定量/心理测量学方法建立测量方法。背景：英国伦敦、爱丁堡、赫特福德郡、索尔兹伯里和南安普顿的8家医疗服务提供者(包括14家诊所，包括产前、堕胎和1名全科医生)。参与者：样本包括怀孕(继续怀孕和选择堕胎)和最近怀孕(堕胎后和出生后)的妇女。在定性阶段，47名妇女参加了深度访谈(其中20人在孩子出生后再次接受采访)。对26名女性进行了项目预测，并对390名和651名女性进行了两次现场心理测试。主要结果：形成了意外怀孕的六个项目测量。心理测量学检验表明该量表具有较高的信度(Cronbach‘sα=0.92；重测信度=0.97)和较高的面子效度、内容效度和结构效度。女性在妊娠计划方面的立场由得分范围(0-12)代表。结论：非计划妊娠的心理测量学测量现在是可用的，其发展是由非专业人士提供信息的。该措施适用于任何妊娠，无论结果如何(即出生、堕胎、流产)，妇女高度接受。
Study objective: To develop a measure of unplanned pregnancy that is valid, reliable, and appropriate in the context of contemporary demographic trends and social mores and can be used in a variety of situations, including the production of population prevalence estimates.Design: A two stage study design: qualitative (inductive) methods to delineate the construct of pregnancy planning, and quantitative/psychometric methods to establish the means of measurement.Setting: Eight health service providers (comprising 14 clinics, including antenatal, abortion, and one general practitioner) across London, Edinburgh, Hertfordshire, Salisbury, and Southampton in the UK. Participants: Samples comprised a mixture of pregnant (continuing pregnancy and opting for abortion) and recently pregnant (post-abortion and postnatal) women. At the qualitative stage, 47 women took part in depth interviews (20 of whom were re-interviewed after the birth of their baby). Items were pre-tested with 26 women, and two psychometric field tests were carried out with, respectively, 390 and 651 women.Main results: A six item measure of unplanned pregnancy was produced. Psychometric testing demonstrated the measure's high reliability (Cronbach's alpha = 0.92; test-retest reliability = 0.97) and high face, content, and construct validity. Women's positions in relation to pregnancy planning are represented by the range of scores (0-12).Conclusions: A psychometric measure of unplanned pregnancy, the development of which was informed by lay views, is now available. The measure is suitable for use with any pregnancy regardless of outcome (that is, birth, abortion, miscarriage) and is highly acceptable to women.
