Acceptability was based on missing data (<10%) and floor-and ceiling effects (<80%), internal consistency was measured by Cronbach‘s α for overall score and subdomains (> 0,7) and correlation between test items and overall score (> 0,3), and test-retest reliability was measured by Intraclass Correlation Coefficient (ICC) for overall score and subdomains (> 0,75).
Aðgengileiki var metinn með hlutfalli ósvaraðra prófatriða (<10%) og gólf- og rjáfuráhrifum (<80%), innri áreiðanleiki var metinn með Cronbach‘s α fyrir heildarútkomu og undirpróf (> 0,7) og fylgni prófatriða við heildarútkomu (> 0,3), og endurtektarprófunaráreiðanleiki var metinn með Intraclass Correlation Coefficient (ICC) fyrir heildarútkomu og undirpróf (> 0,75).
