Abstract
This study examines the mechanisms shaping users' continuance intention toward online meeting platforms. Study 1 used semi-structured interviews with 17 Chinese users, analyzed through grounded theory. Guided by the Cognitive-Affective-Conative framework, Study 2 developed a theoretical model and collected 292 valid online questionnaires via convenience sampling. Covariance-based structural equation modeling (CB-SEM) tested the model. Results show that positive emotions exert the strongest positive effect on continuance intention (β = 0.791***), while negative social presence has a weaker negative effect (β = - 0.164**). Interaction and feedback deficiency (β = 0.58***) and attention distraction (β = 0.292***) significantly increase negative social presence, whereas technical advantages (β = 0.226*) and stress-reducing virtual perception (β = 0.705***) enhance positive emotional experiences. Self-efficacy significantly moderates the relationship between negative social presence and continuance intention. By integrating qualitative exploration with quantitative validation, this study enriches the understanding of continuance intention in online meetings contexts and provides practical insights for optimizing platform design and user retention.
