Introduction: : Establish content and structural validity, internal consistency, inter-rater reliability, and measurement error of the physical and cognitive scales of the Utrecht Scale for Evaluation clinical Rehabilitation (USER) in geriatric rehabilitation. Material and methods: : First, an expert consensus-meeting (N=7) was organised for content validity wherein scale content validity index (CVI) was measured. Second, in a sample of geriatric rehabilitation patient structural validity (N=616) was assessed by confirmatory factor analyses for exploring unidimensionality. Cut-off criteria were: Root Mean Square Error of Approximation (RMSEA) 0.95. Local independence (residual correlation0.30 and Hs-coefficient >0.50) were also calculated. Cronbach alphas were calculated for internal consistency. Alpha's > 0.7 was considered adequate. T hird, two nurses independently administered the USER to 37 patients. Intraclass-correlation coefficients (ICC) were calculated for inter-rater reliability (IRR), standard error of measurement (SEM) and Smallest Detectable Change (SDC). Results: : The CVI for physical functioning was moderate (0.73) and excellent for cognitive functioning (0.97). Structural validity physical scale was acceptable (CFI;0.95, TLI;0.93, RMSEA;0.07, ECV;0.78, OmegaH;0.87; Monotonicity;(Hi;0.52-0.75 and Hs;0.63)). Cognitive scale was good (CFI;0.98, TLI;0.96, RMSEA;0.05, ECV;0.66 and OmegaH;0.90. Monotonicity;(Hi;0.30 -0.70 and Hs;0.61)). Cronbach's alpha were high: physical scale;0.92 and cognitive scale;0.94. Reliability physical scale ICC;0.94, SEM;5 and SDC;14 and cognitive scale ICC;0.88, SEM;5 and SDC;13. Conclusion: : The observational scales of the USER have shown sufficient content and structural validity, internal consistency, and interrater reliability for measuring physical and cognitive function in geriatric rehabilitation.
