Objective To investigate common dyadic coping (CDC) in linking with marital satisfaction and quality of life (QOL) in patients with brain injury and their spouses in a rehabilitation facility by using common fate model (CFM). Methods From October, 2022 to June, 2023, 101 brain injury inpatients and their spouses in Beijing Bo'ai Hospital completed the questionnaire of Dyadic Coping Inventory, Kansas Marital Satisfaction Scale and World Health Organization Quality of Life. The level of CDC between patients and their spouses significantly positively correlated with their marital satisfaction for both partners （β= 0.814, P<0.001), as well as correlated with their quality of life （β=0.271, P= 0.038; β=0.481, P<0.001). For the dimensions of QOL, the physical, psychological, social relationship and environmental dimensions significantly positive correlated with the CDC for the spouses, and only psychological and social relationship dimensions for the patients. Conclusion Facing the stress of brain injury, the level of CDC within couples can positively predict their marital satisfaction and QOL, and effect seems stronger for the spouses. It is advisable to consider both brain injured patients and their spouses as a whole to promote psychological adaptation and improve rehabilitation outcomes.

目的 基于共同命运模型，考察康复机构脑损伤后功能障碍患者与配偶的共同二元应对水平，探讨其与夫妻的婚姻满意度和生活质量的关系。方法 2022年10月至2023年6月，选取北京博爱医院脑损伤住院患者101例，患者夫妻填写共同二元应对量表、Kansas婚姻满意度量表、世界卫生组织生活质量简表。结果 共同二元应对水平与婚姻满意度呈显著正相关(β=0.814, P <0.001)。共同二元应对水平与各自的生活质量呈显著正相关(β=0.271, P=0.038; β=0.481, P <0.001)；其中，配偶在身体健康、心理、社会关系和环境方面均与共同二元应对水平呈显著正相关，患者仅在心理和社会关系维度显著相关。结论 面对脑损伤应激，患者夫妻的共同二元应对水平可正向预测双方的婚姻满意度和生活质量，且对配偶的预测效应更强。宜将患者夫妻作为整体，纳入临床管理，促进双方心理积极适应，提高康复效果。
