Purpose: To evaluate the psychometric properties of the UK FIM + FAM. Methods: (a) A systematic literature review integrating the evidence for psychometric qualities of both the original and UK versions, and (b) exploratory and confirmatory factor analysis of admission/discharge data from an inpatient general neuro-rehabilitation cohort using parametric and non-parametric techniques. A prospective cohort of 459 patients with a male: female ratio of 57: 43 and mean age of 44.5 (SD 14.3) years participated in this study. Results: Seven published articles together demonstrated acceptable utility, concurrent validity, inter-rater reliability and responsiveness of the UK FIM + FAM. Factor analysis demonstrated that all items loaded high (40.58) on the first principal component and distinct motor and cognitive factors emerged after rotation. A four-factor solution also demonstrated four distinct, interpretable dimensions (Physical, Psychosocial, Communication and Extended Activities of Everyday Living (EADL)). Mokken analysis of the second data set confirmed these dimensions. Cronbach%26apos;s alpha s were 0.97 and 0.96 for the motor and cognitive domains and 0.90-0.97 for the subscales. Analysis of responsiveness demonstrated %26quot;large%26quot; effect sizes (0.86-1.29). Conclusions: The UK FIM + FAM, including the newer EADL module, is a valid, reliable scale of functional independence. It has high internal consistency in two domains and four subscales and is responsive to changes occurring in a general inpatient neuro-rehabilitation population.
