However, despite high engagement levels during live streaming sessions, the conversion of viewers into buyers remains relatively low. This study examines how social presence and interactivity influence consumers' purchase intentions in live streaming shopping, with trust serving as a mediating variable. The study adopts the Stimulus–Organism–Response (S–O–R) framework and employs a quantitative causal research design, based on survey data from 234 respondents who had watched live streaming shopping within the past three months. The data were analyzed using Structural Equation Modeling (SEM) with AMOS. The results indicate that social presence and interactivity positively affect trust and purchase intention. Interactivity has the strongest influence on trust, highlighting the importance of responsive communication and real-time engagement. Trust also significantly mediates the relationship between social presence, interactivity, and purchase intention. These findings suggest that live streaming platforms and streamers should prioritize interactive, transparent communication strategies that foster social engagement to strengthen consumer trust and enhance purchase conversion in digital commerce more effectively and sustainably]]>
