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.

项目概要 更好地了解怀孕愿望对于减少意外怀孕至关重要。目前的状态- 最先进的怀孕愿望的概念化和测量受到严重限制 极大地削弱了我们理解将怀孕愿望与随后的怀孕愿望联系起来的过程的能力 怀孕。 拟议项目至少包括三项重大创新：（一）十三项细致入微的措施 怀孕意愿； (2) 衡量伴侣在所有关系中的怀孕愿望的看法 观察期（包括短暂和/或不稳定的关系）； （三）每周各方面措施 怀孕欲望，代表这些欲望的动态。 我们建议通过四个方面来改进对怀孕愿望的概念化、测量和理解 具体目标： 1. 研究怀孕欲望的测量特性 2. 分析伴侣怀孕愿望认知的作用 3. 描述和预测怀孕欲望的动态 4. 估计动态怀孕欲望对后续怀孕的影响 我们建议使用关系动态和社交生活（RDSL）研究中的独特数据集。远程DSL 首先对 1,003 名 18 岁和 19 岁女性进行了面对面的基线调查。未来2.5年，这些 妇女每周提供有关怀孕愿望和怀孕经历的最新信息， 人际关系、避孕药具的使用和相关态度。在为期 2.5 年的研究期间， 2012 年 2 月，年轻女性报告有 233 例怀孕。这里提出的分析不属于 最初的 RDSL 提案。
