Abstract: The influence of online customer reviews (OCRs) on consumer behaviour has recently gained considerable attention, from both academic and business communities. Technology allows customers to freely and easily post their comments and opinions online about any product or service. These types of customer reviews can have a significant effect on customers’ purchase decisions and have become an essential part of the experience when shopping online. However, knowledge of the role of the perceived derived attributes of OCRs on consumer behaviour remains vague. Previous studies have mainly focused on the influence of the virtual attributes of OCRs, such as volume and valence, on consumers’ intentions, while limited attention has been paid to understanding the effects of the derived attributes. This study, thus, aims to understand the effects of the social and functional perceived derived attributes of OCRs on customer trust and intention to shop online. Hence, we develop a research model - Perceived Derived Attributes (PDA) -, based on the integration of social support with functional support derived from OCRs. The PDA model provides an in-depth understanding of the role of the social support of OCRs by applying and utilising theories of social support, social presence and a sense of belonging. The PDA model also investigates the influence of the functional support arising from OCRs through the inclusion of perceived control, from the Theory of Planned Behaviour (TPB) with the Technology Acceptance Model (TAM). The PDA model characterises perceived social support through informational and emotional supports, social presence, and a sense of belonging; whereas, functional supports are characterised by perceived usefulness, perceived ease of use, perceived enjoyment, and perceived control. A total of 489 responses to a survey were collected from users of amazon.com. The results from this study suggest that customer trust in an e-vendor and their intention to shop online are significantly affected by social and functional supports derived from OCRs. In particular, informational support, social presence and a sense of belonging, derived from OCRs were found to positively and significantly affect both customer trust in the online vendor and consumer behavioural intention. However, emotional support was only found to affect customers’ intentions and not their trust in the e-vendor. Additionally, customer trust in an e-vendor and their intention to shop online are significantly affected by perceived usefulness, perceived ease of use and perceived enjoyment of OCRs. Furthermore, the sense of control derived from OCRs significantly affects customer intention and significantly affects customer trust in e-vendors but only for customers who frequently check OCRs before making a purchase. This study is the first to introduce and empirically test the effects of perceived derived attributes of OCRs on customer trust and behavioural intention. Understanding the effects of such influencing factors is of utmost importance for both theoretical development and business practices. Clearly, these attributes of OCRs are linked to the development of the shopping environment, representing a promising marketing tool that positively affects customers’ behaviour.
