AbstractBrand -extension strategies enhance success chances of new products, even though they expose brand

image to dilution risks. The present work analyzes how brand -extension evaluation can affect the current

brand image and proposes a theoretical model formed by five main factors related to brand associations,

extension congruency and extension attitude. The model estimation includes structural equation analysis using

data from 699 surveys developed under market conditions. The results verify that extension attitude influencesbrand image, whereas initial brand associations and perceived fit between the new product and either the

remaining products (category fit) or the brand image (image fit) are able to strengthen consumer attitude. The

study also explains the role of consumer innovativeness as a moderating factor, suggesting that the

characteristics of consumer personality could be more important than expected.
