title: Associations between psychotic-like experiences and mental health status and other psychopathologies among Japanese early teens.
abstract: Psychotic-like experiences (PLEs) are considered predictive of mental health problems later in life. However, little has been known about the mental health status and psychopathological distress in adolescents with PLEs in the general population. To investigate the associations between PLEs and mental health status or psychopathologies in a community sample of adolescents in a school-based cross-sectional fashion, PLEs were studied using a self-rating questionnaire in 5073 Japanese junior-high school students aged 12-15 years. Mental health status was evaluated using the 12-item General Health Questionnaire (GHQ-12). Psychopathologies, lifestyle, victimization, and interpersonal and help-seeking attitudes were also studied using a self-rating questionnaire. Fifteen percent of the students reported definitely having experienced at least one PLE. A dose-response relationship between the severity of PLEs and the prevalence of poor mental health status was observed. PLEs were also significantly associated with psychopathologies (strong anxiety in the classroom: OR = 1.4, 95% CI 1.2-1.6; suicidal ideation: OR = 2.1, 95% CI 1.8-2.4; self-harm behaviors: OR = 1.4, 95% CI 1.0-1.9; difficulty falling asleep due to hypersensitivity to environmental noise: OR = 1.7, 95% CI 1.4-2.0; difficulty concentrating due to hypersensitivity to environmental noise: OR = 1.5, 95% CI 1.3-1.8; physically assaulting others: OR = 1.3, 95% CI 1.0-1.5; bullying others, OR = 1.3, 95% CI 1.1-1.5; irritability when exchanging e-mails: OR = 1.3, 95% CI 1.0-1.6). Adolescents with PLEs in the community suffer from a wide range of psychopathological problems during crucial developmental periods [corrected]
