| Objective:This study employs a scoping review to systematically analyze the core elements, implementation forms, and outcomes of intergenerational mutual aid models. It establishes a theoretical framework to inform strategies for active aging and an age-friendly society.Methods:Relevant literature on intergenerational mutual-aid elderly care published up to July 30, 2025, was retrieved from nine Chinese and international databases. Two researchers independently screened the literature, extracted data, and conducted the analysis.Results:A total of 38 articles were included, spanning 12 countries such as China, Australia, and the USA. The review comprises 12 quantitative, 12 qualitative, and 14 mixed-methods studies. Key participants in the intergenerational mutual aid model include older adults, youth/children, and professionals. The model fosters reciprocal empowerment through skills transmission, health promotion, companionship, and daily support, facilitated by 'university-community-institution' collaboration. Implementation is characterized by modularity, scenario-based adaptability, and collaborative networking. Crucially, the model effectively improves older adults' mental health, social engagement, and vitality, while enhancing younger participants' positive attitudes toward aging, social responsibility, and professional identity.Conclusion:This study constructs a systematic theoretical framework featuring "Participants-Content-Operation," revealing the operational logic of intergenerational mutual aid from micro-level resource reciprocity to macro-level ecological reconstruction. Accordingly, we propose a systematic transition toward institutional embedding, evidence-based evaluation, and long-term incentives. By strengthening top-level design, standardized management, and mechanism innovation, this strategy aims to evolve the model from fragmented projects into an age-friendly social ecosystem. |
