Reliability and validity of fim11/3/2023 ![]() A three-factor solution comprising motor, communication and psychosocial subscales, accounting for >69% total variance, provided acceptable fit statistics on CFA (Root Mean Square Error of Approximation was 0.08 and Comparative Fit Index/ Tucker Lewis Index 0.922/0.907). EFA showed a strong general factor accounting for >48% of the total variance. Responsiveness for each subject (change from admission to discharge) was examined using paired t-tests and differences between LHS and RHS for the entire group were examined using non-paired t-tests. For factor analysis, admission and discharge data were pooled and randomised into two equivalent samples the first for exploratory factor analysis (EFA) using principal components analysis, and the second for confirmatory factor analysis (CFA). Complete data were analysed for 1,539 stroke patients (LHS: 588, RHS: 566 with clear localisation). We analysed in-patient episode data from 62 specialist rehabilitation units collated through the UKROC database 2010–2013. ![]() Previously validated in a mixed neurorehabilitation cohort, this study is the first to explore its psychometric properties in a stroke population, and compare left and right hemispheric strokes (LHS vs RHS). ![]() The UK Functional Assessment Measure (UKFIM+FAM) is the principal outcome measure for the UK Rehabilitation Outcomes Collaborative (UKROC) national database for specialist rehabilitation.
