“…As a consequence, in more recent literature there has been increased consideration of the functional outcomes and changes to quality of life (QoL) associated with dysphagia in the HNC population (Llewellyn, Weinman, McGurk, & Humphris, 2008;Lovell, Wong, Loh, Ngo, & Wilson, 2005;Nguyen et al, 2005). Whilst such research has furthered our understanding of the impact of dysphagia following HNC management, the majority of studies to date have applied quantitative methods to measure the extent of functional change (Barringer, Hutcheson, Sturgis, Kies, & Lewin, 2009;Cartmill, Cornwell, Ward, Davidson, & Porceddu, 2011a;Cartmill et al, 2012;Jensen et al, 2007) or change in QoL (Lovell et al, 2005;Maurer et al, 2011;Nguyen et al, 2005). The value of taking a quantitative approach has been to confirm that a problem exists (Llewellyn et al, 2008;Lovell et al, 2005;Murry, Madasu, Martin, & Robbins, 1998;Nguyen et al, 2005).…”
