The British Psychological Society Objectives: Childhood psychotic-like experiences (PLEs) increase risk for concurrent and future psychiatric disorders but are common in the population. Strategies are needed to identify vulnerable individuals who may benefit from monitoring or targeted intervention. This study aimed to delineate profiles of childhood PLEs that might be differentially associated with other psychopathologies, and multiple psychopathology. Design: Cross-sectional, online self-report survey. Methods: Participants were 27,000 Australian children from a population cohort (13,416 girls; mean age 11.91 years) who completed an online self-report questionnaire assessing PLEs (hallucinations and delusions) and Emotional, Peer Relationship, Conduct, and Hyperactivity–Inattention psychopathology. Latent class analysis differentiated classes of children showing different patterns of PLE responses, and multinomial logistic regression determined the association between the PLE classes and the various psychopathologies, adjusted for demographic covariates and the other psychopathologies. Results: Five latent profiles of PLE responses were characterized as follows: None (27.4% of children), Minor (29.7%), Moderate (11.8%), Hallucinatory (21.0%), and Strong (10.2%). These classes showed distinct associations with other psychopathologies (odds ratios between 1.27 and 4.58), and dose–response relationships indicated increasing likelihood of multiple psychopathology for the Hallucinatory and Strong classes (odds ratio = 21.87 for ≥3 psychopathologies in the Strong class). Conclusions: Tailored interventions that address the particular needs of these different classes of individuals may be warranted. Practitioner points: Children aged 11–12 years who report psychotic-like experiences (PLEs) can be classified into five different PLE profiles based on self-reported questionnaire responses, which may reflect different pathological processes. These PLE profiles show different patterns and magnitudes of increased risk for other types of psychopathology, and multiple psychopathology, suggesting that they present different treatment needs. Cross-sectional investigation of the associations between PLE profiles and other psychopathologies limits any conclusions as to the causal direction of these relationships. Multi-informant reports of psychopathology were unavailable.
