E-waste recycling is important for environmental sustainability. Despite the well-established infrastructure in place, only a small portion of users recycle e-waste. The present meta-analysis aimed to investigate the strength of key theory-based correlates of e-waste recycling intentions and behavior. We focused on hypothesized relationships between constructs from four relevant theories (i.e., extended theory of planned behavior, value-belief-norm theory, habit theories, and behavioral reasoning theory). A total of 36 studies were included in the final selection. Studies were coded for four moderators of model effects: age, gender, region of data collection, and study quality. Effect sizes from 37 samples ( = 18,410) were analyzed through bare-bones and psychometric meta-analysis. Consistently with the assumptions of the theory of planned behavior, the relationship between e-waste recycling intentions and actual behavioral outcomes had a very large effect size. Attitudes, policy effectiveness, and convenience were shown to be related to e-waste recycling intentions with very large effect sizes. Studies included presented high heterogeneity. In the final part of the manuscript, we explore methods for pinpointing potential intervention strategies aimed at facilitating e-waste recycling.

电子废物回收意图和行为的心理相关性：荟萃分析

电子废物回收对于环境可持续发展非常重要。尽管基础设施完善，但只有一小部分用户回收电子垃圾。本荟萃分析旨在研究电子废物回收意图和行为的基于关键理论的相关性的强度。我们重点关注四种相关理论（即计划行为的扩展理论、价值信念规范理论、习惯理论和行为推理理论）之间的假设关系。最终入选的研究共有36项。研究针对模型效应的四个调节因素进行编码：年龄、性别、数据收集区域和研究质量。通过简单的心理测量荟萃分析对 37 个样本 (= 18,410) 的效应大小进行了分析。与计划行为理论的假设一致，电子废物回收意图与实际行为结果之间的关系具有非常大的效应量。研究表明，态度、政策有效性和便利性与电子废物回收意图相关，且效应规模非常大。包括的研究呈现出高度异质性。在手稿的最后部分，我们探索了确定旨在促进电子废物回收的潜在干预策略的方法。
