A total of 451 students were assessed utilizing the Adverse Childhood Experiences Scale (ACES), the Meaning in Life Questionnaire (MLQ), the Rosenberg's Self-Esteem Scale (RSES), and the Coping Humor Scale (CHS). Results indicated that: (1) adverse childhood experiences significantly and negatively predicted meaning in life; (2) self-esteem partially mediated the relationship between adverse childhood experiences and meaning in life; (3) humorous coping moderated the first stage of the mediation model, specifically buffering the negative effect of adverse childhood experiences on self-esteem. In summary, adverse childhood experiences reduce meaning in life by impairing self-esteem, whereas enhancing humorous coping abilities can buffer their detrimental effects on self-esteem among college students.
