This applied, quantitative, cross-sectional correlational study was conducted using structural equation modeling. The statistical population consisted of students enrolled at universities in Sirjan during the 2025–2026 academic year. Using multistage cluster random sampling, 209 students were included in the final analysis. Data were collected using the six-item PROMIS Anxiety Short Form, the Toronto Alexithymia Scale-20, and the six-item Problematic Internet Use Questionnaire Short Form. Data analysis was performed using SPSS and AMOS. Pearson correlation, regression analysis, and mediation analysis with 5,000 bootstrap resamples were used to examine the direct and indirect relationships among the variables. Anxiety was positively and significantly correlated with alexithymia (r = .52, p &lt; .01) and Internet addiction (r = .41, p &lt; .01), while alexithymia was positively correlated with Internet addiction (r = .48, p &lt; .01). Anxiety significantly predicted Internet addiction (β = .41, p &lt; .001) and explained 16.8% of its variance. Anxiety also significantly predicted alexithymia (β = .52, p &lt; .001), accounting for 27.0% of its variance. When anxiety and alexithymia were entered simultaneously, alexithymia significantly predicted Internet addiction (β = .38, p &lt; .001), while the direct effect of anxiety remained significant but decreased to β = .18 (p = .011). The indirect effect of anxiety on Internet addiction through alexithymia was significant (effect = .23, SE = .05, 95% CI [.14, .33]), confirming partial mediation. Alexithymia partially mediates the relationship between anxiety and Internet addiction, indicating that anxiety contributes to problematic Internet use both directly and indirectly through greater difficulty in identifying and processing emotions.</p> https://journals.kmanpub.com/index.php/psychnexus/article/download/6172/12053
