Cross-cultural adaptation and reliability evaluation of Iranian version of Functional Assessment Measure in spinal cord injury patients.

BACKGROUND AND PURPOSE: The aim of this study was to translate and validate the Iranian version of the Functional Assessment Measure (FAM) among patients with spinal cord injury (SCI). MATERIAL AND METHODS: Two hundred patients with SCI participated in this study. A convenience sampling approach was used for selection of the patients. The FAM was translated into Persian language and then independently translated back into English. The reliability of the FAM was assessed by test-retest methods with a 14-day interval for interrater reliability. Intraclass correlation coefficient (ICCs) was calculated and interrater reliability and intrarater reliability were assessed. RESULTS: The mean age of the patients was 35.7 years (SD, 7.2) and 86% of patients were male.The Cronbach alpha coefficient for both raters was above 0.70. Intrarater reliability of the Iranian version of the FAM ranged from good to excellent agreement. The highest level of intrarater reliability was observed for Community mobility (ICC = 0.93). There was good to excellent agreement for interrater reliability of the FAM. The FAM could differentiate between subgroups of patients based on the level of injury but not for the time elapsed from the injury. CONCLUSIONS: Based on the results of this study, the Iranian version of the FAM (FAM-Ir) was highly valid and reliable for evaluation of functional ability in patients with SCI. Therefore, we would suggest that the FAM could also be used as an assessment tool for SCI patients.
