The statistical population consisted of all students enrolled in universities in Kermanshah during the second semester of the 2024–2025 academic year. A total of 238 students were selected using convenience sampling. Data were collected using the Social Phobia Inventory, the Dirty Dozen Dark Personality Traits Questionnaire, the Meta-Worry Questionnaire, and the Toronto Alexithymia Scale (TAS-20). Data analysis was conducted at descriptive and inferential levels using SPSS version 21 and SmartPLS version 3, applying the partial least squares approach due to non-normal data distribution.</p> <p><strong>Findings: </strong>Structural equation modeling results indicated that dark personality traits did not have a significant direct effect on social anxiety (p &gt; .05). In contrast, meta-worry showed a positive and significant direct effect on social anxiety (β = 0.42, p &lt; .01). Dark personality traits had a significant positive effect on alexithymia (β = 0.24, p &lt; .01), and meta-worry also had a significant positive effect on alexithymia (β = 0.49, p &lt; .01). Indirect path analyses revealed that dark personality traits were significantly related to social anxiety through alexithymia (β = 0.07, p &lt; .01). Similarly, meta-worry was significantly related to social anxiety through alexithymia (β = 0.14, p &lt; .01). Overall model fit indices indicated a strong and acceptable fit for both the measurement and structural models.</p> <p><strong>Conclusion: </strong>The findings suggest that social anxiety in university students is primarily influenced by meta-worry directly and by dark personality traits indirectly through deficits in emotional awareness, highlighting the central mediating role of alexithymia in translating dispositional and metacognitive vulnerabilities into social anxiety symptoms.</p> </td> </tr> </tbody> </table> <p> </p> https://www.journals.kmanpub.com/index.php/jayps/article/download/5079/10161
