“…Finally, inaccuracies related to the cut-off points could be attenuated if the classifications obtained by applying the distribution-based methods could be supplemented by the information provided by the anchor-based methods (see Barrett, Brown, & Mood, 2008; de Vet & Terwee, 2010; Houweling, 2010; Turner et al, 2010), or the cumulative proportion of responders (Farrar, Dworkin, & Max, 2006; McLeod, Coon, Martin, Fhenel, & Hays, 2011; Wyrwich et al, 2013), but it is still necessary to research this point further. There is also a need to further investigate the appropriateness of using specific cut-off points for each specific context or for each type of disorder (Button et al, 2015; Lemieux, Beaton, Hogg-Johnson, Bordeleau, & Goodwin, 2007; McGlothlin & Lewis, 2014; Revicki et al, 2008; Terwee et al, 2010).…”
