“…A global score can be calculated as the total sum of scores on all seven items, where higher scores suggest better HA fi tting outcome (Cox & Alexander, 2002). The psychometric properties of the IOI-HA have been evaluated for English speaking populations (Cox & Alexander, 2002;Stephens, 2002;Smith et al, 2009;Hickson et al, 2010) and for a few other languages Heuermann et al, 2005; Br ä nnstr ö m & Wennerstr ö m, 2010; Liu et al, 2011) including Danish Jespersen et al, 2005;Vestergaard, 2006). Previous studies indicate that the IOI-HA is infl uenced by two factors, one pertaining to introspection ( ' me and my hearing aid ' ; items 1, 2, 4, and 7) and one to interaction ( ' me and the rest of the world ' ; items 3, 5, and 6) (Cox & Alexander, 2002;Kramer et al, 2002;Stephens, 2002;Vestergaard, 2006;Ö berg et al, 2007;Br ä nnstr ö m & Wennerstr ö m, 2010).…”
