中国残障群体人口众多，由于生理、心理、经济、社会文化等原因而长期处于社会弱势地位，提高其幸福水平和生活质量是社会公平的必然要求。伴随着数字媒体的发展，残障群体拥有了更多突破身体局限，更深程度融入社会、实现自我发展的机会。因此，探讨残障群体的数字媒体使用对完善信息无障碍建设、实现残障群体数字融入的美好愿景具有现实意义。本研究以视障群体为研究对象，聚焦于视障群体数字媒体使用对主观幸福感的影响及作用机制。本研究在残障研究的“人类发展模型”和“生理-心理-社会”模型两个理论框架的指导下，采用了问卷调查法和访谈法两种研究方法，从视障群体的数字媒体使用习惯切入，以探讨影响视障者主观幸福感的影响因素为重点，选择了从生理、心理、社会三个维度分析数字媒体使用对视障者主观幸福感的影响。研究发现，视障者对数字媒体使用形成了较高程度的依赖，认为数字媒体在他们的生活中起到较为积极的作用。关于视障者的主观幸福感，本研究发现了一条数字媒体使用通过社会融入的完全中介作用间接影响其主观幸福感的影响路径，即“数字媒体连通性-社会融入-主观幸福感”；此外，社会融入也在社会支持与视障者主观幸福感之间发挥了部分中介作用。研究还发现，复原力在视障者通过使用数字媒体进行的沟通和传播中被构建和发展，并对幸福感产生了促进作用，帮助他们更好地面对生活。论文从视障者数字媒体使用习惯出发，探讨了影响视障者主观幸福感的因素与机制，呈现出数字媒体使用对视障者主观幸福感的促进作用，发现了社会支持、社会融入、复原力等社会心理因素对其主观幸福感的重要影响。本研究力求平衡理论价值与现实意义，同时兼顾人文关怀，从生理、心理、社会三个维度回应了数字媒体普及与发展对于残障群体等弱势群体的影响；本研究通过提供大量实证材料进一步丰富和扩充了现有残障群体的传播学研究，同时扩展了复原力传播理论对于特殊群体的适用性，具有一定的理论价值。此外，本研究对于推动信息无障碍建设和残障群体平等融入数字社会有一定的现实意义，为发展残疾人事业和谋求残疾人福祉提供传播学视角的理论思考。

China has a large population of disabled people, who have been in a disadvantaged position in society for a long time due to physical, psychological, economic, social and cultural reasons. Improving their happiness level and quality of life is an inevitable requirement of social equity. With the development of digital media, people with disabilities have more opportunities to break through physical limitations, integrate deeper into society and realize self-development. Therefore, it is of practical significance to explore the use of digital media by the disabled to improve the information barrier-free construction and realize the beautiful vision of digital integration of the disabled.This study takes the visually impaired as the research object, focusing on the influence and mechanism of digital media use on subjective well-being of visually impaired people. Guided by the two theoretical frameworks of "human development model" and "biopsychosocial" model of disability research, this study adopts two research methods of questionnaire survey and interview. Starting from the habit of using digital media of visually impaired groups, this study focuses on exploring the influencing factors of visually impaired people's subjective well-being. This paper analyzes the effects of digital media use on the subjective well-being of visually impaired people from three dimensions: biological, psychological and social.The study finds that the visually impaired people have formed a high degree of dependence on the use of digital media, believing that digital media plays a relatively positive role in their lives. As for the subjective well-being of visually impaired people, this study finds a path that digital media use indirectly affects their subjective well-being through the full mediating effect of social integration, namely "digital media connection-social inclusion-subjective well-being". In addition, social inclusion also plays a partially mediating role in the relationship between social support and subjective well-being of visually impaired people. The study also finds that resilience is built and developed in communication through the use of digital media by visually impaired people, and has a positive effect on well-being, helping them to cope better with life.Based on the habit of using digital media, this paper discusses the factors and mechanisms that influence the subjective well-being of visually impaired people, shows the promoting effect of using digital media on the subjective well-being of visually impaired people, and discovers the important influence of social psychological factors such as social support, social inclusion and resilience on their subjective well-being. This study tries to balance the theoretical value and practical significance, while taking humanistic care into account, and responds to the impact of the popularization and development of digital media on vulnerable groups such as the disabled from three dimensions of physiology, psychology and society. By providing a large amount of empirical materials, this study further enrichis and expands the existing communication studies on disabled groups, and at the same time expands the applicability of resilience communication theory to special groups, which has certain theoretical value. In addition, this study has certain practical significance for promoting the construction of information accessibility and equal integration of disabled groups into the digital society, and provides theoretical thinking from the perspective of communication for the development of the cause of the disabled and seeking the well-being of the disabled.
