BACKGROUND: Health supplements and natural products are widely used by the general public to support physical function and prevent disease. Additionally, with the advent of e-commerce, these products have become easily accessible to the general public. Although several theoretical models have been used to explain the use of health supplements and natural products, empirical evidence on how consumers make decisions to purchase online health supplements and natural products remains limited.
METHODS: In this study, a grounded theory approach was used to develop a substantive theoretical model with the aim of investigating the decision-making process of consumers when purchasing health supplements and natural products online. Malaysian adult consumers who had purchased these products via the Internet were either purposively or theoretically sampled. A total of 18 virtual in-depth interviews (IDIs) were conducted to elicit participants' experiences and priorities in relation to this activity. All the IDIs were audio-recorded and transcribed verbatim. The data were analysed using open coding, focus coding and theoretical coding. The analytical interpretations and theoretical concepts were recorded in research memos.
RESULTS: Consumers' decisions to purchase a health supplement or natural product over the Internet are based on a series of assessments regarding the perceived benefits and risks of this activity, which may be related to the product or the process. In the online marketplace, consumers attempt to choose products, online sellers, sales platforms and/or purchase mechanisms with lower perceived risk, which ultimately enhances their confidence in five elements related to the purchase: (1) product effectiveness, (2) product safety, (3) purchase convenience, (4) fair purchase and (5) online security. Consumers take an acceptable level of risk to purchase these products online, and this acceptable level is unique to each individual and is based on their perception of having control over the potential consequences if the worst-case scenario occurs.
CONCLUSIONS: In this study, a substantive theoretical model is developed to demonstrate how consumers decide to purchase online health supplements and natural products by accepting an acceptable level of risk associated with the product or process. The emerging model is potentially transferable to other populations in similar contexts.
