With the development of the internet, people’s pursuit of reading entertainment has enriched internet novels, but the relevant influencing factors are still unclear. Therefore, we recruited 344 Chinese college students and employed a questionnaire survey to explore the relationship between alexithymia, boredom proneness, and internet novel addiction. The results showed that (1) there was no significant difference between female and male college students in terms of alexithymia and boredom proneness, whereas male college students had a higher total score of internet novel addiction than females. (2) There were significant positive correlations between alexithymia, boredom proneness, and internet novel addiction. (3) Boredom proneness played a partial mediating role in the impact of alexithymia on the internet novel addiction. Taken together, alexithymia may directly and indirectly predict internet novel addiction through boredom proneness.
