This special issue of Adoption Quarterly highlights recent longitudinal findings from the Minnesota/Texas Adoption Research Project (MTARP), which began in the 1980s and has followed 169 birth mothers and 190 adoptive families (190 mothers, 190 fathers, 171 children, now adults) over four waves of data collection (30 years postplacement) to identify the effects of adoption over time for all parties involved. The original sample was recruited from 35 private adoption agencies in 23 different states across the United States. The lead authors (Grotevant & McRoy) of this special issue have published the initial findings in two books (Openness in Adoption: New Practices, New Issues [1988] and Openness in Adoption: Exploring Family Connections [1998]), which highlighted the early findings related to outcomes for birth mothers, adopted children, and adoptive families involved in MTARP. Subsequently, the project has published its empirical findings in more than 50 articles in refereed journals as well as numerous book chapters and pieces for broader audiences. This special issue features four new articles that focus on MTARP findings from the most recent waves of data collection. They focus on birth parents, adoptive parents, and adopted persons as well as the research process and use both qualitative and quantitative approaches. These articles examine (1) predictors of adoptive mothers’ and fathers’ psychological distress while their children are adolescents; (2) emerging adult adoptees and their quest for information about their birth parents; (3) intergenerational relationships in open adoptions from the perspective of birth mothers, now birth grandmothers; and (4) ethical considerations in navigating confidentiality and privacy when conducting research with multiple parties in the adoption kinship network across time. Brief descriptions of these articles are provided below.

超越童年：领养亲属网络的开放性

本期收养季刊特刊重点介绍了明尼苏达州/德克萨斯州收养研究项目 (MTARP) 的最新纵向调查结果，该项目始于 1980 年代，跟踪了 169 位生母和 190 个收养家庭（190 位母亲、190 位父亲、171 名儿童，现在是成年人）超过四波数据收集（安置后 30 年）以确定随着时间的推移采用对所有相关方的影响。原始样本是从美国 23 个不同州的 35 家私人收养机构中招募的。本期特刊的主要作者 (Grotevant & McRoy) 在两本书（收养中的开放性：新实践、新问题 [1988] 和收养中的开放性：探索家庭联系 [1998]）中发表了初步发现，其中强调了早期与生母、收养儿童的结果相关的调查结果，以及参与 MTARP 的收养家庭。随后，该项目在权威期刊上发表了 50 多篇文章以及众多书籍章节和文章，供更广泛的读者阅读。本期特刊刊登了四篇新文章，重点介绍了最近一波数据收集中的 MTARP 调查结果。他们关注亲生父母、养父母和收养人以及研究过程，并使用定性和定量方法。这些文章研究了 (1) 养母和养父在其子女处于青少年时期时心理困扰的预测因素；(2) 新兴成年被收养者及其对亲生父母信息的查询；(3) 从生母、现生祖母的角度看，公开收养中的代际关系；(4) 跨时间与收养亲属网络中的多方进行研究时，在处理机密性和隐私方面的道德考虑。下面提供了这些文章的简要说明。
