The aim of this study was to fill the lack of knowledge regarding a more grounded exploration of the consumer's decision-making process in the context of generic drugs. In this perspective, a model, within the theoretical framework of the Theory of Planned Behaviour (TPB), for studying the consumers' purchase intention of generic drugs was developed.
An online survey on 2,222 Italian people who bought drugs in the past was conducted. The proposed model was tested through structural equation modelling (SEM).
Almost all the constructs considered in the model, except the perceived behavioural control, contribute to explain the consumer's purchase intention of generic drugs, after controlling for demographic variables (age, income, education). Specifically, attitude, subjective norm, past behaviour, self-identity and trust in the pharmacist have a positive influence on the intention to buy generic drugs. On the contrary, perceived risk towards products and brand sensitivity act negatively.
The results of the present study could be useful to public policy makers in developing effective policies and educational campaigns aimed at promoting generic drugs. Specifically, marketing efforts should be directed to inform consumers about the generic drugs' characteristics to mitigate the perceived risk towards these products and to raise awareness during their decision-making process.
本研究旨在填补在仿制药背景下对消费者决策过程进行更深入探索方面的知识空白。从这个角度出发,在计划行为理论(TPB)的理论框架内,开发了一个用于研究消费者购买仿制药意愿的模型。
对2222名过去购买过药品的意大利人进行了在线调查。通过结构方程模型(SEM)对所提出的模型进行了测试。
在控制了人口统计学变量(年龄、收入、教育程度)后,除了感知行为控制外,模型中考虑的几乎所有构念都有助于解释消费者购买仿制药的意愿。具体而言,态度、主观规范、过去行为、自我认同和对药剂师的信任对购买仿制药的意愿有积极影响。相反,对产品的感知风险和品牌敏感度则产生负面影响。
本研究结果可能有助于公共政策制定者制定有效的政策和开展教育活动以促进仿制药的使用。具体而言,营销努力应旨在向消费者宣传仿制药的特点,以减轻对这些产品的感知风险,并在其决策过程中提高认识。
