Consumers have enjoyed shopping via the web for over a decade, but the emergence of shopping through social media or social commerce is slowly gaining traction Instagram is one of the largest interactive photo-sharing sites that retailers, specifically apparel and accessory companies, are utilizing to sell their merchandise. Consumers are increasingly using this platform to engage, discover and get inspired; therefore, it is critical for retailers to understand how this platform influences purchase intention. This paper focuses on analyzing the impact of Instagram on consumer’s purchase intention based on an adapted model of Technology Acceptance Model and Theory of Reasoned Action. Using multi-group analysis, consumers (n=317) were divided into two groups: shopped for fashion products (including browsing, making a one-time purchase, or making repeat purchases) or not shopped using Instagram for apparel specific brands. The participants were surveyed using an online instrument with questions related to attitude, subjective norms, normative beliefs, perceived usefulness (PU), perceived ease of use (PEOU) and purchase intention. Frequency statistics were obtained for the demographic variables. Overwhelmingly (approximately 78%), respondents used Instagram daily with 82.6% following an apparel brand. 40% of the respondents had shopped previously on Instagram (i.e. browsed as well as purchased products), with 13% of these respondents spending more than $100. An exploratory factor analysis using principal component with varimax rotation and a minimum eigen value of one was used to identify the latent variables in the model: PEOU (α = 0.82); PU (α = 0.81); Normative Beliefs (α = 0.81); Attitude (α = .87); Subjective Norm (α = 0.88); Purchase Intention (α = 0.79). Results indicated that subjective norms did not influence purchase intention for both the groups indicating that consumers do not follow “groupthink” mentality while intending to purchase via Instagram. Furthermore, it was found that PEOU influence on attitude for the two groups of consumer were different, with no impact for the group who had shopped on Instagram. All the other relationships were supported in the model. These results provide both implications and limitations for retailers and academia.
