Psychotic-like experiences (PLEs) in adolescence are found to be risk factors for later mental disorders. Previous research has also found that childhood trauma has a positive correlation with mental health problems. However, few studies have focused on the relationship between them, especially in adolescence and early adulthood. A total of 9122 students (age between 10 and 23.3) were surveyed and assessed with the positive and depressive subscales of the Community Assessment of Psychic Experiences and the Trauma History Questionnaire. A total of 20.7% students experienced frequent PLEs, 17.5% had frequent delusional experiences, and 7.6% had frequent hallucinatory experiences. Only a small portion of this sample experienced frequent PLEs, associated with more types of PLEs, more distress, and more depressive experiences. Several socio-demographic factors were associated with frequent PLEs in this sample, which could be further examined in future prevention studies. Students with frequent PLEs experienced significantly higher impact from trauma events, both at the time of the events and in the present, indicating a possible reciprocal effect between childhood trauma and PLEs. The impact of childhood trauma played an important role in the relationship between childhood trauma and PLEs.
