物体。脑动脉瘤可以通过破裂和中风、对神经结构的冲击、治疗副作用或心理压力来影响患者的健康状况。作者评估了简表-12(SF-12)的性能、效度和可靠性，该量表是一种自我管理的书面调查工具，用于评估脑动脉瘤患者的健康状况。对在神经外科诊所就诊的170名脑动脉瘤患者进行了结构化访谈，包括测量他们的健康状况(SF-12身体成分摘要[PCS]和精神成分摘要[MCS])、功能状况(格拉斯哥结果量表评分、改良Rankin量表评分和Barthel指数)和心理健康(医院焦虑和抑郁量表评分)。SF-12得分与美国人群常模的比较采用不等方差的t检验。采用秩序法将PCS和MCS评分与患者的功能状态和心理健康评分进行比较，评价SF-12的效度。条目间的可靠性用Cronbachα统计进行评估。与人群正常值(P<；0.001)相比，脑动脉瘤患者的健康状况评分和MCS评分降低。蛛网膜下腔出血病史(p=0.006)和既往手术或血管内治疗(p=0.047)与PCS评分较差有关。SF-12的有效性得到了PCS和MCS评分与患者的功能状态和心理健康之间的关系的支持(p<；0.001)。用Cronbachα统计量记录SF-12的信度(α=0.76)。根据SF-12的测量，脑动脉瘤患者的身心健康状况有所下降。蛛网膜下腔出血和动脉瘤治疗与较差的身体健康状况有关。SF-12是测量脑动脉瘤患者健康状况的有效和可靠的工具。
Object. Cerebral aneurysms can affect a patient's health status by rupture and stroke, impingement on neural structures, treatment side effects, or psychological stress. The authors assessed the performance, validity, and reliability of the Short Form-12 (SF-12), a self-administered written survey instrument, to assess health status in patients with cerebral aneurysms.Methods. A cohort of 170 patients with cerebral aneurysms who were seen at a neurosurgery clinic underwent structured interviews including measurement of their health statuses (SF- 12 physical component summary [PCS] and mental component summary [MCS]), functional status (Glasgow Outcome Scale score, modified Rankin Scale score, and Barthel Index), and mental health (Hospital Anxiety and Depression Scale score). The SF-12 scores were compared with US population norms by performing t-tests with unequal variances. The validity of the SF-12 was assessed by comparing the PCS and MCS scores with each patient's functional status and mental health scores by using rank-order methods. Inter-item reliability was assessed using the Cronbach alpha statistic.Patients with cerebral aneurysms had decreased health status PCS and MCS scores when compared with population norms (p < 0.001 for all). A history of subarachnoid hemorrhage (SAH) (p = 0.006) and previous surgical or endovascular treatment (p = 0.047) was associated with worse PCS scores. The validity of the SF-12 was supported by the relationship between the PCS and MCS scores and the patient's functional status and mental health (p < 0.001 for all). The reliability of the SF-12 was documented by the Cronbach alpha statistic (alpha = 0.76).Conclusions. Patients with cerebral aneurysms have a diminished physical and mental health status as measured using the SF-12. The presence of SAH and aneurysm treatment are associated with a worse physical health status. The SF- 12 is a valid and reliable instrument for measuring health status in patients with cerebral aneurysms.
