Mass customized products, compared with mass marketed alternatives, offer advantages for optimizing performance outcomes, improving aesthetic appeal, and matching products' symbolic meanings with consumers' expressive desires. Despite having identified these value drivers for mass customized products, extant research has not connected those value drivers to individual differences among consumers. As a result, researchers' and practitioners' abilities to predict consumer value for mass customized products remain limited. This study advances and tests a model of individual differences associated with the perceived value of a customized product and mediated by involvement and perceived risk. A field survey administered to a sample of 240 participants provided data to test the model. Path analysis using structural equations modeling suggests that consumer value for mass customized products differs according to individual differences in need for uniqueness, need for optimization, and centrality of visual product aesthetics. Results also suggest that product category involvement and perceived risk are informative theoretical perspectives from which to study consumer value for mass customized products. The findings hold implications for how firms should approach the design of mass customization toolkits and how they should structure marketing communications promoting mass customized products.
