Objective

To evaluate the psychometric properties of the Spinal Cord Injury–Functional Index (SCI-FI) instruments in a community-dwelling sample.

Design

Cross-sectional study.

Setting

Community setting.

Participants

Individuals (N=269) recruited from 6 SCI Model Systems sites.

Interventions

Not applicable.

Main Outcome Measures

Participants completed computer adaptive test and short form versions of 4 SCI-FI/Capacity (C) banks (ie, Ambulation, Basic Mobility, Fine Motor, Self-Care) and 1 SCI-FI/Assistive Technology (AT) bank (Wheelchair Mobility) at baseline and after 2 weeks. The Self-Report Functional Measure (SRFM) and the clinician-rated motor FIM were used to evaluate evidence of convergent validity.

Results

Pearson correlations, intraclass correlation coefficients, minimal detectable change, and Bland-Altman plots supported the test-retest reliability of the SCI-FI instruments. Correlations were large with the SRFM (.69-.89) and moderate-to-large for the FIM instrument (.44-.64), supporting convergent validity. Known-groups validity was demonstrated by a significant main effect of injury level on all instruments and a main effect of injury completeness on the SCI-FI/C instruments. A ceiling effect was detected for individuals with incomplete paraplegia on the Fine Motor/C and Self-Care/C Short Forms.

Conclusion

Findings support the test-retest reliability, convergent validity, and known-groups validity of the SCI-FI/C instruments and the SCI-FI/AT Wheelchair Mobility instruments for use by community-dwelling individuals.

脊髓损伤功能指数的验证用于社区居住的 SCI 个体

客观的

评估社区住宅样本中脊髓损伤功能指数 (SCI-FI) 仪器的心理测量特性。

设计

横断面研究。

环境

社区设置。

参与者

从 6 个 SCI 模型系统站点招募的个人 (N=269)。

干预措施

不适用。

主要观察指标

参与者完成了 4 个 SCI-FI/容量 (C) 库（即步行、基本移动、精细运动、自我护理）和 1 个 SCI-FI/辅助技术 (AT) 库（轮椅移动）的计算机自适应测试和简短版本) 在基线和 2 周后。自我报告功能测量 (SRFM) 和临床医生评定的运动 FIM 用于评估收敛有效性的证据。

结果

Pearson 相关性、组内相关系数、最小可检测变化和 Bland-Altman 图支持 SCI-FI 仪器的重测信度。与 SRFM (.69-.89) 的相关性很大，与 FIM 工具 (.44-.64) 的相关性为中到大，支持收敛效度。已知组有效性通过损伤水平对所有工具的显着主效应和损伤完整性对 SCI-FI/C 工具的主效应来证明。在 Fine Motor/C 和 Self-Care/C Short Forms 上检测到不完全截瘫个体的天花板效应。
