This study examined the mediating role of the sense of coherence in the relationship between positive childhood experiences and alexithymia. The research was conducted with a total of 507 participants, including 259 women and 248 men aged over 18, selected through convenience sampling. Data were collected using a Personal Information Form, the Positive Childhood Experiences Scale, the Toronto Alexithymia Scale, and the Sense of Coherence Scale. Data analysis was performed using SPSS 25 and the PROCESS macro. The results indicated that positive childhood experiences significantly and positively predicted levels of sense of coherence, while they significantly and negatively predicted alexithymia. Furthermore, the sense of coherence was found to significantly and negatively predict alexithymia. It was also found that the sense of coherence mediated the relationship between positive childhood experiences and alexithymia.
