Previous research suggests that community-based participation, a process through which beneficiaries can actively influence and define the direction and execution of development programs, can promote long-term uptake, use, and management of shared resources, such as community-based safe water infrastructure. However, results are heterogeneous. Psychological ownership theory and initial evidence suggests that participation promotes positive outcomes for shared resources by fostering sense of ownership through three routes: having control, intimate knowledge, and investing the self. This study used community-based safe water infrastructure as an example to investigate how various forms of participation affect acceptance, use, and functionality of a shared resource and whether this effect is mediated by psychological ownership. We conducted a nonrandomized cluster-based controlled trial with pre–post intervention assessment (N = 369) in 33 villages in rural Nepal, where safe water infrastructure is shared. Participatory intervention activities (e.g., influence in decision-making, contributing materials and labour) favourably affected self-reported outcomes and use of the water supply infrastructure but not observed functionality or drinking water quality. In conclusion, this study supports the assumption that participation can foster psychological ownership, which in turn can support successful management of a shared resource.

先前的研究表明，基于社区的参与（受益人可以通过该过程积极影响和确定发展计划的方向和执行）可以促进共享资源的长期吸收、使用和管理，例如基于社区的安全水基础设施. 然而，结果是异质的。心理所有权理论和初步证据表明，参与通过三种途径培养主人翁意识来促进共享资源的积极成果：拥有控制权、深入了解和投资自我。本研究以基于社区的安全用水基础设施为例，调查各种形式的参与如何影响共享资源的接受、使用和功能，以及这种影响是否由心理所有权介导。我们在尼泊尔农村的 33 个村庄进行了一项非随机的、基于集群的对照试验，并进行了干预前评估（N = 369），这些村庄共享了安全的水基础设施。参与式干预活动（例如，对决策的影响、提供材料和劳动力）对自我报告的结果和供水基础设施的使用产生了有利影响，但未观察到功能或饮用水质量。总之，这项研究支持这样的假设，即参与可以促进心理所有权，这反过来又可以支持共享资源的成功管理。贡献的材料和劳动力）对自我报告的结果和供水基础设施的使用产生了有利影响，但未观察到功能或饮用水质量。总之，这项研究支持这样的假设，即参与可以促进心理所有权，这反过来又可以支持共享资源的成功管理。贡献的材料和劳动力）对自我报告的结果和供水基础设施的使用产生了有利影响，但未观察到功能或饮用水质量。总之，这项研究支持这样的假设，即参与可以促进心理所有权，这反过来又可以支持共享资源的成功管理。
