Reliability and validity of the Greek adaptation of the Modified Barthel Index in neurorehabilitation patients

The Modified Barthel Index (MBI) is a tool used to assess a patient's ability to perform daily activities. This study aimed to create a Greek version of the MBI and test its reliability and validity in Greek neuro-rehabilitation patients. The MBI was translated and adapted for cultural relevance, then administered to 100 rehabilitation patients, who were also assessed using other validated questionnaires to check the MBI's validity. The study found that the Greek version of the MBI is a reliable and valid tool for assessing functional ability in Greek neuro-rehabilitation patients.

  The study rejected the unidimensionality of the MBI, adopting a two-factor solution: Transfers and Activities of Daily Living, and Mobility.
• 2
  The Greek MBI showed high correlation with the Katz Index and SF-36 physical functioning subscale, indicating good criterion validity.
• 3
  The Greek version of the MBI demonstrated excellent internal consistency and test-retest reliability.
