The aim of this validation study was to assess intrarater and interrater reliability using this modified version of PASS at a stroke unit for patients in the acute phase after their first event of stroke. Methods In the intrarater reliability study 114 patients and in the interrater reliability study 15 patients were examined twice with the test within one to 24 hours in the first week after stroke. Spearman s rank correlation Kappa coefficients Percentage Agreement and the newer rank-invariant methods Relative Position Relative Concentration and Relative rank Variance were used for the statistical analysis. Results For the intrarater reliability Spearman s rank correlations were and k were for the individual items. Small statistically significant differences were found for two items regarding Relative Position and for one item regarding Relative Concentration. There was no Relative rank Variance for any single item. For the interrater reliability Spearman s rank correlations were for individual items. For some items there was a possible even if not proved reliability problem regarding Relative Position and Relative Concentration. There was no Relative rank Variance for the single items except for a small Relative rank Variance for one item. Conclusions The high intrarater and interrater .
