This study aims to explore the relationship between attachment styles and self-concept, and further analyze the moderating effect of PhoPhiKat in this relationship. Data were collected using an online questionnaire, with 342 Taiwanese college students aged 18 to 25 participating. The measurement tools used include the "Interpersonal Attachment Style Scale," the "College Students' Self-Concept Scale," and the Chinese version of the " PhoPhiKat-TC scale." Through descriptive statistics and hierarchical regression analysis, the study examined the correlation between attachment styles and self-concept, as well as the moderating effect of PhoPhiKat on this relationship. The results revealed that (1) secure attachment is significantly positively correlated with self-concept; (2) insecure attachment is not significantly negatively correlated with self-concept; (3) gelotophobes do not moderate the relationship between secure attachment and self-concept; (4) among those with high levels of gelotophobia, the positive correlation between anxious attachment and self-concept is higher than among those with low levels of gelotophobia; (5) katagelao does not moderate the relationship between secure attachment and self-concept; (6) katagelao does not moderate the relationship between insecure attachment and self-concept; (7) gelotophilia does not moderate the relationship between secure attachment and self-concept; (8) gelotophilia does not moderate the relationship between insecure attachment and self-concept. Finally, based on the study results, explanations and suggestions for both research and practical implications are provided.
