3.5. Dependent variable
The dependent variable, consumer attitude towards the store brand, was operationalized in accordance with previous studies in branding research (Aaker and Keller, 1990; Van Riel et al., 2001), by averaging two measures: the perceived overall quality of the store brand (1=inferior, 7=superior) and the likelihood of purchas- ing the store brand, assuming that the customer was planning a purchase in the product category (1=not at all likely, 7=very likely). For this variable, a reliability coefficient a of 0.87 was obtained.
