This study evaluated the validity of the Functional Independence Measure (FIM instrument) in predicting (1) the number of minutes of daily assistance provided, (2) the cost of durable goods currently used, and (3) the number of paid helper hours provided daily to persons with spinal cord injury living in the community.
A cross-sectional study.
One hundred nine persons with spinal cord injury who were a median 6 years postdischarge from initial medical rehabilitation.
A significant inverse linear relationship was observed between FIM scores and the square root values of the three cost-related measures. The FIM-18 and the FIM motor scores were the best single predictors of the square root of minutes of assistance (paid and/or unpaid) per day, explaining 85% of variance. The FIM motor measure was the best single predictor of square root of cost of durable goods, explaining 29% of variance. The Self-Care, FIM motor, and FIM-18 scores equally predicted square root of hours of paid help per day, explaining 58% of variance.
The findings indicate FIM-related scores predict the amount of assistance needed and certain costs for persons with spinal cord injury disability.
本研究评估了功能独立性测量（FIM工具）在预测以下方面的有效性：（1）每日提供的协助分钟数；（2）当前使用的耐用物品成本；（3）每天为居住在社区的脊髓损伤患者提供的有偿帮助时长。
横断面研究。
109名脊髓损伤患者，自初次医疗康复出院的中位时间为6年。
观察到FIM评分与三项成本相关指标的平方根值之间存在显著的负线性关系。FIM - 18和FIM运动评分是每日协助分钟数（有偿和/或无偿）平方根的最佳单一预测指标，解释了85%的方差。FIM运动测量是耐用物品成本平方根的最佳单一预测指标，解释了29%的方差。自理、FIM运动和FIM - 18评分同样可以预测每日有偿帮助时长的平方根，解释了58%的方差。
研究结果表明，与FIM相关的评分可预测脊髓损伤残疾患者所需的协助量和特定成本。
