Intergenerational interactions and exchange are major components of grandparenting, and the present study sought to examine how the intergenerational solidarity framework has been used to investigate grandparenting practices across the lifespan and in different cultures. This framework is widely used across cultures and provides a basis to discuss the future of grandparenting research, considering cultural intermingling and changes in society. Following PRISMA-ScR guidelines, we searched three databases (PsycInfo, PubMed, and Web of Science). Finally, 42 empirical studies that met the inclusion criteria were included in this scoping review. They were published between 1991 and 2020 and assessed intergenerational solidarity between grandparents and their grandchildren. Our findings show that research on grandparenting based on the intergenerational solidarity framework has increased in the last 30 years, and that this model provides a comprehensive approach to studying grandparenting across the lifespan in different cultures. The present study identified cross-cultural differences in the prevalence of the types of intergenerational solidarity. Affectual solidarity was shown to be the most studied dimension of intergenerational solidarity in North America, Europe and Israel, while normative solidarity was the most represented in Asian studies. The only Australian study investigated affectual and functional solidarity. This model is thus suitable for studying grandparenting, but further studies are needed to investigate changes in intergenerational solidarity between grandparents and their grandchildren at different stages of development and account for cultural specificities.

代际互动和交流是祖父母养育的主要组成部分，本研究试图探讨如何使用代际团结框架来调查祖父母一生中和不同文化中的祖父母养育实践。该框架在不同文化中得到广泛应用，并为讨论祖父母研究的未来、考虑文化融合和社会变化提供了基础。遵循 PRISMA-ScR 指南，我们检索了三个数据库（PsycInfo、PubMed 和 Web of Science）。最后，本次范围界定审查纳入了 42 项符合纳入标准的实证研究。它们于 1991 年至 2020 年间出版，评估了祖父母与孙子女之间的代际团结。我们的研究结果表明，基于代际团结框架的祖父母养育研究在过去30年有所增加，并且该模型为研究不同文化中整个生命周期的祖父母养育提供了一种全面的方法。本研究确定了代际团结类型普遍存在的跨文化差异。在北美、欧洲和以色列，情感团结是代际团结研究最多的维度，而规范团结在亚洲研究中代表性最多。澳大利亚唯一的研究调查了情感和功能团结。因此，该模型适合研究祖父母教养，但需要进一步研究来调查祖父母与孙子女之间在不同发展阶段的代际团结的变化，并解释文化特殊性。
