目的：探析社会支持对老年轻度认知障碍（MCI）患者的自我效能及生活质量的影响。方法：采取便 利抽样法选择我院收治的诊断为 MCI 的患者 206 例，使用一般人口学资料调查表、领悟社会支持量表 （PSSS）、一般自我效能量表（GSES）及阿尔茨海默病生活质量汉译量表（QOL-AD）对患者及其家属进行问 卷调查并分析。结果：本组206 MCI例患者的QOL-AD总分为（32.05±2.31）分，GSES评分为（33.45±3.57） 分，PSSS评分为（53.14±4.35）分，均处于中低程度水平。不同年龄、文化程度、当前居住地、当前居住状况、 家庭收入、医疗支付方式、人际关系状况患者的 QOL-AD 差异有统计学意义（P＜0.05）。MCI 患者的 QOL-AD评分中各项均与PSSS量表中的社会支持总分呈显著正相关（P＜0.05），MCI患者的QOL-AD评分 中的身体健康状况、精力、情绪、居住情况、记忆力、与家人关系、婚姻状况、对自己的整体感觉与GSES总分 呈显著正相关（P＜0.05）。结论：临床医护人员应重视老年MCI患者的自我效能感，充分应用社会支持，制 定科学可行、高质量的自我管理项目和方案，提升生命质量，延缓阿尔茨海默病的进程。

To explore the effect of social support on the self-efficacy and quality of life of elderly patients with mild cognitive impairment (MCI). Methods: Convenience sampling was used to select 206 MCI patients in our hospital. A survey and analysis were conducted on patients and their family using the general demographic data questionnaire, perception of social support scale (PSSS), general self-efficacy scale (GSES), and Chinese translation of the Alzheimer’s disease quality of life scale (QOL-AD). Results: The 206 MCI patients had a QOL-AD total score of (32.05±2.31), GSES score of (33.45±3.57), and PSSS score of (53.14±4.35), all of which were considered low-moderate levels. Patients with a different age, education level, location of residence, condition of residence, family income, mode of medical expense, and quality of interpersonal relationships showed a significant difference in QOL-AD score (P<0.05). All item scores on the QOL-AD were positively correlated with the social support score of the PSSS (P<0.05). The physical health, energy, mood, living conditions, memory, relationship with family members, marital status, and overall feelings about oneself item scores on the QOL-AD were significantly positively correlated with the GSES total score (P<0.05). Conclusion: Clinical medical staff should recognize the self-efficacy of elderly patients with MCI, promote the utilization of social support, and formulate scientifically feasible and high-quality self-management projects and programs, so as to improve the quality of life and delay the progression of Alzheimer’s disease.
