3 Wolfs et al (2007) To compare the construct validity and responsiveness of the 3 L version of the EQ-5D and the 3L version + cognition in elderly patients Individuals were recruited as part of a randomized controlled trial in the Netherlands. The 3 L version of the EQ-5D was initially collected from the individuals’ proxies. Subsequently, the mini mental state examination and the cognition dimension were administered. Spearman’s rank correlations were used to analyse the association between the EQ-5D and the mini mental state examination, and the EQ-5D + cognition and the mini mental state examination at baseline, 6 and 12 months with 234 Authors found that correlations between the EQ-5D overall score, the individual dimensions and the mini mental health state were generally moderate. Also the correlation between the cognition dimension and the mini mental health state was moderate. Although, this was higher than the correlation of both the overall idenx and the individual dimensions at baseline, 6 months and 12 months, authors concluded that the performs sufficiently well without the addition of cognition
