Inconsistent trauma reporting is associated with emotional and behavioural problems and psychotic experiences in young people.

ABSTRACT: BACKGROUND:Little is known about the prevalence of inconsistent trauma reporting in community samples and about its associations with psychopathology. This study aimed to assess for the first time the prevalence of inconsistent trauma reporting in a community sample of children/adolescents and to explore associations with both psychotic experiences and with psychopathology more generally. METHOD:A community-based sample of 86 children/adolescents (baseline mean age 11.5) were interviewed at two time points with data collected in relation to potentially traumatic events through the K-SADS. Emotional and behavioural problems were assessed at follow-up (mean age 15.7) through the Youth Self Report questionnaire while the presence of psychotic experiences was based on expert consensus post interview. Logistic regression models were used to test associations between inconsistent reporting and psychotic experiences at baseline and follow-up, with associations with emotional and behavioral problems at follow-up also assessed. RESULTS:Overall, 16.3% of adolescents failed to report previously reported potentially traumatic events at follow-up and were therefore defined as inconsistent trauma reporters. Inconsistent reporting was associated with emotional and behavioural problems as assessed by the Youth Self Report with the exception of rule breaking behaviour and with psychotic experiences as assessed on interview. CONCLUSIONS:Inconsistent trauma reporting is associated with psychotic experiences and emotional and behavioural problems in young people and may represent an important marker for psychopathology in youth.

Project description:Psychotic experiences (PEs) occur in 5-10% of the general population and are associated with exposure to childhood trauma and obstetric complications. However, the neurobiological mechanisms underlying these associations are unclear. Using the Avon Longitudinal Study of Parents and Children (ALSPAC), we studied 138 young people aged 20 with PEs (n = 49 suspected, n = 53 definite, n = 36 psychotic disorder) and 275 controls. Voxel-based morphometry assessed whether MRI measures of grey matter volume were associated with (i) PEs, (ii) cumulative childhood psychological trauma (weighted summary score of 6 trauma types), (iii) cumulative pre/peri-natal risk factors for psychosis (weighted summary score of 16 risk factors), and (iv) the interaction between PEs and cumulative trauma or pre/peri-natal risk. PEs were associated with smaller left posterior cingulate (pFWE < 0.001, Z = 4.19) and thalamus volumes (pFWE = 0.006, Z = 3.91). Cumulative pre/perinatal risk was associated with smaller left subgenual cingulate volume (pFWE < 0.001, Z = 4.54). A significant interaction between PEs and cumulative pre/perinatal risk found larger striatum (pFWE = 0.04, Z = 3.89) and smaller right insula volume extending into the supramarginal gyrus and superior temporal gyrus (pFWE = 0.002, Z = 4.79), specifically in those with definite PEs and psychotic disorder. Cumulative childhood trauma was associated with larger left dorsal striatum (pFWE = 0.002, Z = 3.65), right prefrontal cortex (pFWE < 0.001, Z = 4.63) and smaller left insula volume in all participants (pFWE = 0.03, Z = 3.60), and there was no interaction with PEs group. In summary, pre/peri-natal risk factors and childhood psychological trauma impact similar brain pathways, namely smaller insula and larger striatum volumes. The effect of pre/perinatal risk was greatest in those with more severe PEs, whereas effects of trauma were seen in all participants. In conclusion, environmental risk factors affect brain networks implicated in schizophrenia, which may increase an individual's propensity to develop later psychotic disorders.
