The Functional Independence Measure (FIM™) and spinal cord injury (SCI)-specific Spinal Cord Independence Measure (SCIM) are commonly used tools for outcome measurement and quality reporting in rehabilitation. The objective of this study was to investigate the psychometric properties of FIM™ and SCIM and to equate the 2 scales.
First, content equivalence of FIM™ and SCIM was established through qualitative linking with the International Classification for Functioning, Disability and Health (ICF). Secondly, a Rasch analysis of overlapping contents determined the metric properties of the scales and provided the empirical basis for scale equating. Furthermore, a transformation table for FIM™ and SCIM was created and evaluated.
Patients with SCI in Swiss inpatient rehabilitation in 2017-18.
The ICF linking and a separate Rasch analysis of FIM™ restricted the analysis to the motor scales of FIM™ and SCIM. The Rasch analysis of these scales showed good metric properties. The co-calibration of FIM™ and SCIM motor scores was supported with good fit to the Rasch model. The operational range of SCIM is larger than for FIM™ motor scale.
This study supports the advantage of using SCIM compared with FIM™ for assessing the functional independence of patients with SCI in rehabilitation.
功能独立性测量(FIM™)和脊髓损伤(SCI)专用脊髓独立性测量(SCIM)是康复中常用的结果测量和质量报告工具。本研究的目的是调查 FIM™和 SCIM 的心理测量特性,并使这两个量表等效。
首先,通过与国际功能、残疾和健康分类(ICF)的定性联系,确定了 FIM™和 SCIM 的内容等效性。其次,重叠内容的 Rasch 分析确定了量表的度量属性,并为量表等效提供了经验基础。此外,创建和评估了 FIM™和 SCIM 的转换表。
2017-18 年瑞士住院康复的 SCI 患者。
ICF 链接和 FIM™的单独 Rasch 分析将分析限制在 FIM™和 SCIM 的运动量表上。这些量表的 Rasch 分析显示出良好的度量属性。FIM™和 SCIM 运动评分的共同校准得到了对 Rasch 模型的良好拟合的支持。SCIM 的操作范围大于 FIM™运动量表。
本研究支持在康复中使用 SCIM 评估 SCI 患者的功能独立性优于 FIM™。
