目的：确定儿童功能独立性量表（Weepage）的信度和效度等心理测量学特性，有助于医务人员了解痉挛型脑瘫（CP）患儿的综合评定。本研究旨在探讨痉挛型脑瘫儿童韦氏量表的因素结构。研究方法：在这项横断面研究中招募了207名痉挛性CP儿童（138名男孩，69名女孩），他们的平均年龄（SD）为9.10（2.7）岁。通过问卷调查收集数据，其中包括Weeker。在207名儿童中，分别有57名（27%）、105名（51%）和45名（22%）为四肢瘫痪、双瘫和偏瘫。在这些组中，分别有49名（24%）、32名（15%）、31名（15%）、19名（9%）和76名（37%）儿童被归类为粗大运动功能分类系统（GMFCS）I-V级。运用AMOS20.0软件对大学生心理健康状况进行探索性因素分析和验证性因素分析。通过计算Cronbach’s a的内部一致性来评价Weewestern的信度。结果：Cronbach’s a的内部一致性为0.98。根据CFA，1-和2-因素模型没有表现出足够的拟合指数。然而，三因素结构（即自我照顾，运动和认知因素）的支持，解释了87.12%的方差的探索性因素分析和验证性因素分析。自我照顾因子包括6个项目（进食、梳洗、穿上、穿下、洗澡和排便），运动因子包括7个项目（膀胱和肠道管理、床/椅子/轮椅、厕所、浴缸/淋浴、行走/轮椅和楼梯），认知因子包括与原始认知领域相同的5个项目。结论：痉挛型脑瘫患儿的心理因素中，有3个因素是由因子分析确定的。因此，自我照顾，运动和认知领域应被视为单独的规模在痉挛型CP儿童。
Purpose: Determining the psychometric properties such as reliability and validity of Functional Independence Measure for Children (WeeFIM) instrument would help health professionals to understand the comprehensive assessment of children with spastic cerebral palsy (CP). The purpose of this study was to investigate the factor structure of the WeeFIM in children with spastic CP. Methods: Two hundred seven children (138 boys, 69 girls) with spastic CP were recruited in this cross-sectional study; their mean age (SD) was 9.10 (2.7) years. Data were collected through a questionnaire that included the WeeFIM. Of the 207 children, 57 (27%), 105 (51%), and 45 (22%) were quadriplegic, diplegic, and hemiplegic, respectively. In each of these groups, 49 (24%), 32 (15%), 31 (15%), 19 (9%), and 76 (37%) children were classified as Gross Motor Function Classification System (GMFCS) levels I-V, respectively. The factor structure of the WeeFIM was analyzed by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) by using AMOS 20.0. The reliability of WeeFIM was assessed by calculating the internal consistency of Cronbach's a. Results: The internal consistency of Cronbach's a was 0.98. The 1- and 2-factor models did not demonstrate adequate fit indices according to CFA. However, the 3-factor structure (i.e. self-care, motor, and cognitive factors) was supported by EFA and CFA, which explained 87.12% of the variance. The self-care factor included 6 items (eating, grooming, dressing upper, dressing lower, bathing, and toileting), the motor factor included 7 items (bladder and bowel management, bed/chair/wheelchair, toilet, tub/shower, walk/wheelchair, and stairs), and the cognitive factor included the same 5 items as the original cognitive domain. Conclusion: In children with spastic CP, 3 factors of the WeeFIM were determined by factor analysis. Therefore, self-care, motor, and cognitive domains should be treated as separate scales in children with spastic CP.
