Childhood psychotic experiences are associated with poorer global functioning throughout adolescence and into early adulthood

Background Psychotic experiences (PEs) are common in childhood and have been associated with concurrent mental disorder and poorer global functioning. Little is known about the effects of childhood PEs on future functioning. We investigated the effects of childhood PEs on global functioning from childhood into early adulthood. Method Fifty‐six participants from a community sample completed all three waves of the Adolescent Brain Development study (T1x¯ Age: 11.69, T2x¯ Age: 15.80 T3x¯Age: 18.80). At each phase, participants completed a clinical interview assessing for PEs, mental disorder and global function. Repeated measures models, adjusted for mental disorder and gender, were used to compare current (C‐GAF) and most severe past (MSP‐GAF) functioning in participants who had reported PEs in childhood and controls. Results Participants with a history of PEs had significantly poorer C‐GAF (P
