With the rapid entry into an aging society and the increasing older population suffering from chronic diseases, social and industrial interest in arthritis assistive apparel designed to support physical functions and aid independence in daily life is growing. Arthritis assistive apparel is a product in which not only the medical function of relieving physical pain but also the aesthetic attributes as clothing worn daily or exposed externally are crucial. However, existing studies have primarily focused on functional improvements through product design or verifying medical efficacy, with limited attention paid to the psychological mechanisms and acceptance behaviors of older consumers who actually use the products. In particular, since older consumers tend to feel significant uncertainty about new technologies or products, it is essential to understand the process by which product attributes form trust and lead to intention to use. Furthermore, although product acceptance patterns may vary depending on willingness to learn, which reflects information processing ability and attitude toward novelty within the older demographic, empirical discussion on this topic remains insufficient.
Accordingly, this study aims to examine the effects of the core characteristics of arthritis assistive apparel (relative advantage, compatibility) and its expressive attribute (perceived aesthetics) on trust and intention to use, based on the Diffusion of Innovations Theory. In addition, the study aims to provide a deep understanding of older consumer behavior and derive effective marketing strategies by empirically verifying whether the willingness to learn, a personal characteristic of older consumers, moderates the relationships between product attributes, trust, and intention to use.
To address the research questions, a survey was conducted on 300 male and female older consumers aged 60 and over who experience arthritis or joint pain. Stimuli containing product descriptions and images of assistive apparel for the knee, waist, and wrist were presented to the respondents before data collection. Excluding insincere responses, valid samples were analyzed using SPSS 26.0 and SmartPLS 4.0 to perform frequency analysis, confirmatory factor analysis (CFA), structural equation modeling (SEM), and moderation analysis.
The analysis results are as follows: First, relative advantage, compatibility, and perceived aesthetics of arthritis assistive apparel all had a significant positive (+) influence on the intention to use. Second, among product attributes, relative advantage and perceived aesthetics had a significant positive effect on trust formation, whereas compatibility did not significantly affect trust. Third, the formed trust was found to have a strong positive effect on the intention to use. Fourth, the verification of the moderating effect of willingness to learn revealed that willingness to learn significantly moderated the relationship between compatibility and intention to use, as well as the relationship between trust and intention to use. Specifically, in the group with high willingness to learn, the influence of trust on intention to use was strengthened, whereas in the group with low willingness to learn, the influence of compatibility on intention to use was more pronounced.
This study holds academic significance in that it expands the scope of arthritis assistive apparel research from a functionality-centered approach to a consumer behavior perspective and proves that perceived aesthetics and trust play decisive roles in product acceptance by older consumers. It also offers practical implications by not viewing older consumers as a homogeneous group but segmenting them according to their willingness to learn. Based on the results, marketing practitioners should establish differentiated strategies: emphasizing trust through objective quality certification and professional information for consumers with high willingness to learn, while highlighting familiarity and ease of use for those with low willingness to learn. Through this, this study presents practical guidelines for enhancing the quality of life for consumers and promoting product acceptance in the senior-friendly industry.
