2006, Journal of Clinical EpidemiologyCitation Excerpt :The response rate and item completion rates were good. Like others, we found that floor effects were acceptable, but ceiling effects were large [14–16], and reliability coefficients exceeded recommended levels [8–14]. Validation by numerical dimension-specific items yielded results that were only slightly worse than those of the alternative versions of the questionnaire.

2004, Archives of Physical Medicine and RehabilitationCitation Excerpt :It must be mentioned that most of the NHP energy category scores reported in the literature were calculated from weighted item scores.37 However, the importance of weighting is under discussion,38,39 and the median score of 33 found in our study is well within the range of values reported in the literature.2,11–13,36 Analysis of concurrent validity showed low correlations (range, .43–.68) between the total scores of all pairs of questionnaires, which indicates that little of the variation in score of 1 questionnaire was explained by the variation in score of another questionnaire.
