This study attempts to understand the moderating roles of in-store marketing by incorporating the effects of shopping motivations on repatronage and word-of-mouth intentions in the context of fashion apparel by applying theories related to self-determination and social impact. Structural equation modeling using data collected from young adult fashion apparel shoppers in Thailand reveals positive effects of shopping motivations. The utilitarian shopping motivation shows a greater effect in predicting loyalty intentions than hedonistic shopping motivation. In-store marketing is shown to have a moderating effect on loyalty intentions, although the influence of each moderator on the investigated direct effects varies. The findings can prove helpful to fashion apparel retailers in developing effective advertising and promotional strategies that correspond to the specific needs of the shoppers to promote store loyalty intentions. © 2016 Informa UK Limited, trading as Taylor & Francis Group.
