Discussion and Conclusions
The theoretical underpinning for Brand Personality
Brand personality has been criticised for a lack of theoretical underpinning (Austin, et al., 2003; Berens and van Riel, 2004). Scale development should ideally begin with a theoretically informed understanding of the construct to be measured (Churchill, 1979), and brand personality measures have been, in the main, derived without such underpinning. However human personality has been frequently cited as the theory most relevant to brand personality. We have challenged that view and identified a number of concerns, most notably that the individual dimensions of each construct with similar labels are far from similar in reality and that the Big 5 human personality framework in itself cannot be regarded as a theory, as it was derived from the data it is supposed to explain and is therefore not independent of what it is meant to explain.
Instead, we propose signalling theory (Spence, 1973; Connelly, et al., 2011) as more relevant because it explains how companies come to edit and shape their communication and to signal only specific aspects of a brand, because they find they work for them in the marketplace. Humans, as customers or employees, benefit from such signals as they can use them in constructing or maintaining their own self-image and in promoting that to others. The theory is also independent of the brand personality construct. Work within this perspective identifies a number of signals from companies to the market or between humans that reflect commonly identified, individual dimensions of brand personality including those we have labelled as Sincerity (Erdem and Swait, 1998; Wang, et al., 2004) and Competence (Spence 1973;Fombrun and Shanley, 1990; Griskevicius, 2007). However the same literature often emphasises the signalling of status (Fehr and Fischbacher, 2003 Griskevicius, et al., 2007 Nelissen and Meijers, 2011) and while status is relevant to Aaker’s original definition of brand personality (the set of human characteristics associated with a brand) it was not clearly identified in early scale development work.
