traits conforming to a circular arrangement in a nonrestrictive correlation pattern wherein<br />

each trait has a neighboring as well as an opposite trait. This more in-depth model of<br />

interpersonal <strong>brand</strong> <strong>personality</strong> focuses on the key dimensions of human <strong>personality</strong><br />

(extraversion and agreeableness) in addition to the five factors developed by Aaker (1997).<br />

The IPC also addresses the need for the negative-type <strong>brand</strong> attributes by including<br />

characteristics such as dominant, quarrelsome, and calculating.<br />

Sweeney and Brandon (2006) stressed that the more detailed IPC is a complimentary<br />

(and not a replacement) measurement to the broader factor-analytical model proposed by<br />

Aaker (1997). Moreover, Diamantopoulus et al. (2005) empirically confirmed that the BPS,<br />

less the “western” item, is reliable and may be used with a different population and a<br />

different <strong>brand</strong> from that which Aaker (1997) used. In addition, Murase and Bojanic (2004)<br />

showed that the BPS obtained acceptable reliability scores (Cronbach’s α values ranged from<br />

.8065-.9179) for all dimensions when the scale was used for cross cultural research. Thus,<br />

Aaker’s framework was used as a basis to achieve the goals of this study.<br />

Brand Loyalty<br />

Many studies have been done to conceptualize, define, and measure <strong>brand</strong> loyalty.<br />

One of the most accepted definitions is that of Oliver (1999, p.34) which states that <strong>brand</strong><br />

loyalty is “a deeply held commitment to rebuy or repatronize a preferred <strong>brand</strong> consistently<br />

in the future, thereby causing repetitive same <strong>brand</strong> or same <strong>brand</strong>-set purchasing, despite<br />

situational influences and marketing efforts having the potential to cause switching<br />

behavior.” This definition is consistent with earlier work by Jacoby and Chestnut (1978),<br />

which specified three conditions for <strong>brand</strong> loyalty to exist. First, the consumer’s information<br />

base should indicate that their focal <strong>brand</strong> is more superior to other <strong>brand</strong>s in its class.<br />

Secondly, the consumer must like the <strong>brand</strong> more than others in its class. And lastly, when<br />

purchase situations arise, the consumer must decide to patronize their focal <strong>brand</strong> instead of<br />

any other <strong>brand</strong> in its class. Jacoby and Chestnut (1978) further specified four kinds of <strong>brand</strong><br />

loyalty:<br />

1. True focal <strong>brand</strong> loyalty is when the consumer demonstrates loyalty to the <strong>brand</strong><br />

that is being investigated, referred to as the focal <strong>brand</strong>. For example, if the<br />
