Epidemiological studies of psychotic-like experiences (PLEs) have reported that people who had PLEs during childhood oradolescence have higher incidences of schizophrenia spectrum disorders or other psychiatric disorders later in life than peoplewho have not had PLEs. Previous work has shown that approximately 15% of children in the city of Tsu had PLEs. In thisstudy, we sought to confirm the prevalence of PLEs in early teens living in Nagasaki and to elucidate the associations betweenPLEs and other psychopathological items. To this end, we used a self-report questionnaire to sample approximately 5,000 students(aged 12-15 years) in public junior high schools. Similar to the results of previous studies, the prevalence of PLEs was16.4%. There was a significant association between PLEs and poor mental health status, which was estimated using a 12-itemGeneral Health Questionnaire. Moreover, after controlling for confounding factors, we found a significant association betweenPLEs and a lack of satisfaction with family relationships and several other psychosocial problems. These results suggest thata relatively large proportion of children with PLEs have behavioral, social, or familial problems, which may facilitate futureschizophrenic symptoms
