摘要
目的:应用Rasch分析法,优化中风专用生存质量量表(SS-QOL)的活动域及上肢功能域的测评水平。方法:收集符合研究标准的急性期缺血性中风患者60例,随机分为试验组(30例)和对照组(30例)。试验组给予针刺加常规西药治疗,对照组给予常规西药治疗。取穴:顶中线、风池、合谷等。1个疗程后,让患者自测SS-QOL量表的活动域及上肢功能域项目。用Rasch模型测试SS-QOL量表的活动域及上肢功能域项目的特征。结果:SS-QOL量表的活动域及上肢功能域的适合度统计结果说明样本和项目的各项参数符合Rasch模型,且具有良好的内在信度和良好的难度分层;SS-QOL量表的活动域及上肢功能域的Inifit及Outfit MnSq(接近受试者及远离受试者能力测量反应的非预期敏感度)值基本介于0.5～1.5之间。结论:将Rasch分析应用于患者报告的临床结局指标的评价,优化了患者报告临床结局指标(PRO)量表——SS-QOL量表的活动域及上肢功能域,从而提高SS-QOL量表活动域及上肢功能域的测评水平。
Objective To optimize the evaluation level of active motor threshold and the functional domain of upper limbs of stroke-specific quality of life （SS-QOL） scale with Rasch analysis. Methods Sixty patients with acute ischemic stroke that were in accord with research criterid were randomly divided into a test group （30 cases） and a control group （30 cases）. Acupuncture treatment and routine western medicine were applied on the test group, and single treatment of routine western medicine was applied on the control group. Selected acupoints were MS 5, Fengchi （GB 20）, Hegu （LI 4）, etc. Active motor threshold and the functional domain of upper limbs of SS-QOL were self-tested by patients after one treating course. The characteristics of the above mentioned items were tested with Rasch model. Results The statistical result on fitness of active motor threshold and the functio- nal domain of upper limbs of SS-QOL showed that every reference of samples and items wosin accord with the Rasch model and has well inner reliability and validity. The Infit and Outfit MnSq values of active motor threshold and the functional domain of upper limbs of SS-QOL are basically between 0.5 and 1.5. Conclusion The application of Rasch analysis on the assessment of patient reported outcome （PRO） has optimized the PRO scale （the activity and upper limb function domain of SS-QOL scale） and enhanced evaluation level of active motor threshold and the functional domain of upper limbs of SS-QOL scale.
