Psychometrics of the observational scales of the Utrecht Scale for Evaluation of Rehabilitation (USER): Content and structural validity, internal consistency and reliability

: Establish content and structural validity, internal consistency, inter-rater reliability, measurement error of the physical cognitive scales Utrecht Scale for Evaluation clinical Rehabilitation (USER) in geriatric rehabilitation. First, an expert consensus-meeting (N=7) was organised validity wherein scale index (CVI) measured. Second, a sample rehabilitation patient (N=616) assessed by confirmatory factor analyses exploring unidimensionality. Cut-off criteria were: Root Mean Square Error Approximation (RMSEA) ?0.08; Comparative Fit Index (CFI) Tucker Lewis (TLI) ?0.95. Local independence (residual correlation<0.20) monotonicity (Hi-coefficient ?0.30 Hs-coefficient ?0.50) were also calculated. Cronbach alphas calculated consistency. Alpha's > 0.7 considered adequate. Third, two nurses independently administered USER to 37 patients. Intraclass-correlation coefficients (ICC) reliability (IRR), standard (SEM) Smallest Detectable Change (SDC). The CVI functioning moderate (0.73) excellent (0.97). Structural acceptable (CFI;0.95, TLI;0.93, RMSEA;0.07, ECV;0.78, OmegaH;0.87; Monotonicity;(Hi;0.52-0.75 Hs;0.63)). Cognitive good (CFI;0.98, TLI;0.96, RMSEA;0.05, ECV;0.66 OmegaH;0.90. Monotonicity;(Hi;0.30 –0.70 Hs;0.61)). Cronbach's alpha high: scale;0.92 scale;0.94. Reliability ICC;0.94, SEM;5 SDC;14 ICC;0.88, SDC;13. observational have shown sufficient interrater measuring function N/A
