The current study uses risk theory to explore factors mitigating consumers’ intention to use SSTs. The findings of an empricial study reveal that the perceived time, security and addiction risk indirectly reduce consumers’ intention to use SSTs through the per-ceived psychological risk. Most importantly, this study’s findings show that an increas-ing autonomy of SSTs strengthens the effects of perceived addiction risk.
