Childhood Trauma and Psychosis: An Updated Review.
Does childhood trauma play a role in the aetiology of psychosis? A review of recent evidence
TLDR
Evidence of the association between specific childhood trauma subtypes and psychotic symptoms is examined, and some current hypotheses about the potential mechanisms underlying the associations that have been found are examined.
Trauma and psychosis symptoms in a sample of help-seeking youth
Social Adversity in the Etiology of Psychosis: A Review of the Evidence.
TLDR
It is suggested that if social adversities are of central importance in psychosis, then psychotherapy that addresses the long term sequelae of those adversities should be considered an essential aspect of treatment.
[Substance abuse: a relationship with childhood traumas].
TLDR
A reduction of child abuse may decrease the prevalence of mental disorders, including addictive disorders, and improve mental health.
Distinguishing schizophrenia from posttraumatic stress disorder with psychosis
TLDR
A large genome-wide association study (GWAS) has identified a collection of genes associated with PTSD, and these genes overlap with those identified as increasing the risk of developing schizophrenia.
Relationship between Early Psychotraumatisation with the Onset and the Course of Psychotic Disorders.
TLDR
There is now strong evidence that the prevalence of childhood adversities in this population is exceptionally high, and it seems that this relation is causal, especially when considering severity, frequency, and number of traumatic events.

TLDR
Much more research is needed before firm conclusions can be drawn about whether childhood trauma is a cause of psychosis, and a small number of recent population-based studies provide more robust evidence of an association.
Trauma and psychosis: an analysis of the National Comorbidity Survey.
TLDR
Overall, physical abuse predicted psychosis, and there was a significant cumulative relationship between trauma and psychosis, with number of trauma types experienced increasing the probability of psychosis.

TLDR
Evidence on a) the magnitude of association between PTSD and psychosis, b) the causal mechanisms implicated, and c) treatment considerations relevant to this association are reviewed are reviewed.

TLDR
The associations between sexual trauma, physical abuse, bullying, and being brought up in institutional or local authority care and reports of auditory hallucinations and paranoid beliefs in the 2007 Adult Psychiatric Morbidity Survey are examined.
Childhood Adversities Increase the Risk of Psychosis: A Meta-analysis of Patient-Control, Prospective- and Cross-sectional Cohort Studies
TLDR
It is shown that childhood adversity is strongly associated with increased risk for psychosis and population attributable risk was 33% (16%–47%).

TLDR
This study indicated the added risk of multiple traumatic experiences in psychosis, and there appeared to be a dose-response type relationship.
The varying impact of type, timing and frequency of exposure to childhood adversity on its association with adult psychotic disorder
TLDR
Only specific adverse childhood experiences are associated with psychotic disorders and only in a minority of cases, suggesting that research into the mechanisms underlying the pathway from childhood adversity to psychosis is more fruitful.
Pretreatment and outcome correlates of sexual and physical trauma in an epidemiological cohort of first-episode psychosis patients.
TLDR
SPA prevalence is high in FEP patients and must be explored by clinicians considering its durable impact on psychological balance and link with long-lasting suicidal risk, as well as to develop psychological interventions adapted to this very sensitive and complex issue.
