Can childhood trauma predict future psychosis in adolescents receiving psychiatric inpatient care?

In this article, Dr Valentina Kieseppä,Youth-GEMs’ postdoctoral researcher at the University of Oulu, explains the findings of a recent study exploring whether childhood traumatic experiences can help identify adolescents at the highest risk of developing psychotic disorders later in life.

Adolescents who receive psychiatric care, especially those admitted to a psychiatric hospital, have a higher risk of developing psychotic disorders in adulthood. Childhood traumatic experiences, such as physical or sexual abuse, have also been linked to an increased risk of psychosis later in life. In this study, we investigated whether a history of trauma could help identify which adolescents receiving psychiatric inpatient care are at the highest risk of developing psychosis.

The study followed 404 adolescents who had been admitted to a psychiatric inpatient unit during their teenage years and who had no previous or current diagnosis of psychosis at the time of admission.

During their hospital stay, participants were asked about traumatic experiences using the Kiddie Schedule for Affective Disorders and Schizophrenia. The main analyses focused on childhood physical and/or sexual abuse, while secondary analyses examined other potentially traumatic experiences, including car accidents, other accidents, fires, witnessing disasters or violent crimes, being the victim of a violent crime, receiving traumatic news, witnessing domestic violence, and other traumatic events.

Among the 404 participants, 14% reported a history of childhood sexual abuse and 27% reported childhood physical abuse. However, neither childhood sexual nor physical abuse was associated with a higher risk of developing schizophrenia spectrum disorders (SSDs) in adulthood. Likewise, none of the other types of traumatic experiences examined were linked to an increased risk of SSDs.

We found that childhood trauma was not associated with future psychosis risk among psychiatric adolescent inpatients. These findings suggest that risk factors identified in the general population do not necessarily predict the same outcomes in clinical populations.

Given the high risk for future psychosis in adolescent inpatients, however, more research is needed to figure out what might predict schizophrenia risk in this group. And research on how to reduce this risk.

Esmeralda Ruiz Pujadas

Co-lead WP6

Universidad de Barcelona  

Mental disorders are the third most common cause of disease burden, starting at a young age. Mental illnesses are often recurrent, reducing the quality of life for young people. This is the main reason why Esmeralda has decided to join this project. Esmeralda hopes to ‘do her bit’ to help improve mental health and wishes that mental health will gain more attention thanks to the Youth-Gems project, one of the major initiatives for this purpose. To achieve this, she will be developing models among help-seeking young people to predict mental health outcomes, as well as studying different trajectories to gain new insights into youth mental health. She also aims for the proposed models to be trustworthy, ensuring they are explainable and fair across all subgroups of the population.

Jonathan Mill, heads a group at the University of Exeter (UK) that studies the causes and consequences of genomic variation in the human brain and the role this plays in mental illness and other brain disorders. In particular they explore the way in which gene expression changes in specific brain cell types across development, and how disruptions to this might influence the risk of disease. Johnatan co-leads WP4 and his work in Youth-GEMS aims to characterize patterns of epigenomic and transcriptional regulation during key points in prenatal development and early childhood. In his view, the molecular marks studied in the project are particularly interesting as they potentially play a role at the interface between both genetic and non-genetic risk factors.

Jim van Os

Professor of Psychiatry, Chair of the Brain Division

UMC Utrecht

Jim van Os, born in Utrecht in 1960, is a Professor of Psychiatry and also serves as the Chair of the Brain Division at UMC Utrecht. He is a member of both the Royal Netherlands Academy of Arts and Sciences and the Royal Holland Society of Sciences and Humanities. His work focuses on critically evaluating the prevailing model of mental suffering, which is often simplistically portrayed as being ‘sick in the head.’ He argues that this approach has had little positive impact on the quality of mental health care in the Western world and may even have contributed to the notable increase in mental disorders among young people. 

Van Os views academic psychiatry and psychology as ‘pre-sciences’ that urgently need more layered and complex models of mental suffering, taking into account its social-collectivist causes and the necessity for broad salutogenesis and resilience-building (public mental health). He raises the crucial question of how mental health care should be organized in a society where the annual prevalence of mental suffering is 25%, a question that has so far remained largely unaddressed in research. 

Jim van Os advocates for a new approach to mental health care, one that is rooted in epistemic pluralism: the idea that mental suffering can be viewed through multiple lenses (social, medical, spiritual, lifestyle, existential, physical, post-traumatic) and that individuals should have the ability to choose how and from which framework they wish to work on change.
