Embedded in Uncertainty Reduction Theory, investigation explores how three key UGC characteristics-trustworthiness, valence, and information richness-systematically alleviate dimensions of product uncertainty: performance, description, and fit, respectively. Data were collected through an online survey from 455 Tunisian active online shoppers. Results were analyzed by means of CB-SEM. Findings reveal a powerful mediating pathway whereby UGC characteristics explain 68% of the variance in uncertainty reduction, which in turn significantly predicts purchase intention (R² = 0.59). Importantly, the effects are differentiated: information richness most strongly reduces performance and description uncertainty, while valence is the primary driver of fit uncertainty reduction. Trustworthiness consistently underpins all dimensions. These results develop theory by detailing the cognitive, uncertainty-driven mechanisms of UGC and afford managers actionable insights into how to tailor UGC strategies based on different product types and consumer concerns.</p> |
