Today, food has surpassed travel to become one of the most actively pursued themes by key opinion leaders in Taiwan, making it one of the most popular types among social media users. Food influencers share food content and reviews, not only influencing consumer behavioral intentions but also profoundly affecting consumers' evaluations of the usefulness of shared content, engagement, and adoption attitudes. It has become an important criterion for people to evaluate whether a restaurant is worth tasting or visiting. This study uses the Information Adoption Model (IAM) to explore the relationship between the quality and credibility of food content sources and consumer behavioral intentions (willingness to taste, willingness to continue usage). It observes the impact of perceived usefulness on information adoption attitudes and food community engagement to understand whether source credibility affects food community engagement and consequently affects consumer behavioral intentions. The study constructed a questionnaire based on past literature and revised three questions after examination by 10 heterogeneous experts. The formal questionnaire was distributed via purposive sampling on Facebook, Instagram, Dcard, and LINE communities from March 2 to March 13 in the year 2024, with a total of 552 responses collected, of which 519 were valid (a valid response rate of 94.1%). Descriptive statistics and reliability analysis were conducted using SPSS 23.0, followed by structural equation modeling using AMOS 26.0. The results show significant correlations among the various dimensions of the IAM model. Perceived usefulness plays an intermediary role in the influence of food content quality and source credibility on information adoption attitudes. Information adoption attitudes also have an intermediary effect on the influence of perceived usefulness on willingness to taste and willingness to continue usage. Food community engagement, as an intermediary variable, has a significant impact on both willingness to taste and willingness to continue usage in the influence of source credibility. It is concluded that food influencers should focus on their social media image, improve the quality of their content, and ensure accurate and reliable sharing. Collaboration with food establishments should involve understanding their offerings to meet consumer expectations. Food establishments should prioritize the selection of food influencers to enhance content quality, expand consumer bases through marketing, and increase brand exposure.IAM模型美食網紅美食社群參與度消費者行為意圖IAMfood influencersfood communities engagementconsumer intentions學術論文
