Dynamic Measures of Pregnancy Intentions and Subsequent Pregnancy

项目总结 更好地了解怀孕欲望对于减少意外怀孕至关重要。当前的状态- 对怀孕欲望的最先进的概念化和测量受到严重的限制 极大地削弱了我们理解将怀孕欲望和随后的 怀孕了。 拟议的项目至少包括三大创新：(1)13项细化和细致入微的措施 怀孕愿望；(2)测量伴侣在所有关系中的怀孕愿望。 观察期(包括短暂和/或不稳定的关系)；(3)所有方面的每周衡量 怀孕欲望，代表了这些欲望的动态。 我们建议通过四个方面来改进对怀孕欲望的概念化、测量和理解 具体目标： 1.孕欲的测量特性研究 2.分析伴侣对怀孕意愿的认知所起的作用 3.描述和预测怀孕欲望的动态变化 4.评估动态怀孕欲望对后续怀孕的影响 我们建议使用来自关系动力学和社会生活(RDSL)研究的一个独特的数据集。RDSL 首先对1003名18岁和19岁的女性进行了面对面的基线调查。在接下来的两年半里，这些 女性每周更新自己的怀孕愿望和怀孕经历， 关系、避孕用法和相关态度。在为期2.5年的研究期间，这一研究结束于 2012年2月，这些年轻女性报告了233例怀孕。这里提出的分析不是 原始的RDSL提案。

PROJECT SUMMARY A better understanding of pregnancy desires is critical for reducing unintended pregnancy. Current state-of- the-art conceptualization and measurement of pregnancy desires suffer from serious limitations that dramatically undermine our ability to understand the processes that link pregnancy desires and subsequent pregnancy. The proposed project includes at least three major innovations: (1) thirteen detailed and nuanced measures of pregnancy desire; (2) measures of perceptions of partners' pregnancy desires across all relationships in the period of observation (including short-lived and/or unstable relationships); (3) weekly measures of all aspects of pregnancy desire, representing the dynamics in these desires. We propose to improve conceptualization, measurement, and understanding of pregnancy desires via four specific aims: 1. Investigate the Measurement Properties of Pregnancy Desires 2. Analyze the Role of Perceptions of Partners' Pregnancy Desires 3. Describe and Predict the Dynamics of Pregnancy Desires 4. Estimate the Influence of Dynamic Pregnancy Desires on Subsequent Pregnancy We propose to use a unique dataset from the Relationship Dynamics and Social Life (RDSL) study. RDSL began with a face-to-face baseline survey of 1,003 18- and 19-year-old women. Over the next 2.5 years, these women provided weekly updates about their desires for pregnancy, and about experiences with pregnancy, relationships, contraceptive use, and related attitudes. Over the 2.5-year study period, which ended in February, 2012, the young women reported 233 pregnancies. The analyses proposed here were not part of the original RDSL proposal.
