(Press-News.org) Prevailing theories about why young people experience psychotic breaks at a young age rely on individual factors like exposure to child abuse, school bullying, or drugs.
But a new study from the NYU Silver School of Social Work suggests that broader social factors, such as racial inequality and experience with police violence, might contribute to the proportionately higher rates of psychosis seen among low-income young adults of color.
The study, “Social Defeat and Psychosis in the United States,” was published today by Schizophrenia Bulletin and authored by NYU Silver associate professor Jordan DeVylder and doctoral students Jacqueline Cosse and Brianna Amos.
The researchers culled the National Survey of Poly-Victimization and Mental Health to explore individual-level and societal, or structural, impacts on early psychosis risk. The sample included 1,584 U.S. participants aged 18-29.
Among the respondents, Blacks, Latinos, multiracial, and Indigenous respondents had 60% higher odds of reporting having experienced one or more psychotic episodes in the prior year compared to white respondents, the study determined.
Furthermore, those who cited an experience involving police violence in had 52% higher odds of reporting one or more delusional or hallucinatory episode in the prior year.
The most widely recognized risk factors for psychosis are spelled out in the “Social Defeat Hypothesis,” an influential theoretical framework used by psychiatrists to treat young adults with psychosis. While the social defeat hypothesis frames risk factors around the impact on the individual, the study shifts the focus to take in account social systems and structural factors.
In the study’s analysis of the U.S. survey, an individual’s sense of “social defeat” can indeed result in psychotic symptoms and can arise from a high frequency of substance use or exposure to bullying, as the theory holds. But the persistence of racial inequality, and related experiences such as exposure to police violence, could also be relevant factors, according to the study. It calls for research into the impact of societal factors that are more prominent in low-income and marginalized communities.
Developed in Northern Europe, the “Social Defeat Hypothesis” has been used by U.S. psychiatrists for over two decades to understand the development of psychosis, a condition that could show a young adult to be at higher risk of suicidal thinking or even schizophrenia.
Under the hypothesis, social defeats, like feeling humiliated, contribute to long-term neurobiological shifts in the brain and dopamine system especially, and are part of what may bring on instances in which an individual loses touch with reality.
In conducting the study, DeVylder, Cosse, and Amos collaborated extensively with fellow social work scholar Lisa Fedina of the University of Michigan, as well as additional NYU Silver doctoral students.
Commenting on findings’ significance, DeVylder said that structural factors may exert a “substantial” influence on an individual risk for psychosis, and could potentially help explain ethno-racial disparities in psychosis in the U.S.
“This potentially means that reducing exposure to systemic factors, like societal racism, may provide mental health benefits similar to individual-focused interventions, like psychotherapy,” he said.

Common gene variant doubles dementia risk for men
2025-05-30
New research has found that men who carry a common genetic variant are twice as likely to develop dementia in their lifetime compared to women.
The research, published in Neurology, used data from the ASPirin in Reducing Events in the Elderly (ASPREE) trial to investigate whether people who had variants in the haemochromatosis (HFE) gene, which is critical for regulating iron levels in the body, might be at increased risk of dementia.
Co-author Professor John Olynyk, from the Curtin Medical School, said one in three people carry one ...

Detecting invisible wounds: New study could change how wound closure is defined
2025-05-30
In patients with diabetic foot ulcers that looked healed and met the current definition of a closed wound, closed ulcers with functionally defective skin that lost more body water were likely to re-open, according to a new National Institutes of Health (NIH) Diabetic Foot Consortium study, led by researchers at the University of Pittsburgh and published today in Diabetes Care.
The U.S. Food and Drug Administration (FDA) currently defines a closed wound as one where the surface is completely covered by new skin and ...
Routine breast cancer screening brings better outcomes for patients
2025-05-30
OAK BROOK, Ill. – Researchers have discovered that, compared to breast cancer that is symptom-detected, patients with breast cancer detected via routine screening mammography are more likely to have improved clinical outcomes, according to a study published today in Radiology: Imaging Cancer, a journal of the Radiological Society of North America (RSNA).
While it is commonly understood that early detection of breast cancer results in better patient outcomes, national cancer registries in the U.S. and Canada don’t track the method ...
New ACS study: Number of cancer survivors in the U.S. reaches 18.6 million — projected to exceed 22 million by 2035

Innovative immunotherapy shows promise against aggressive T cell cancers
2025-05-30
A new type of immunotherapy that targets aggressive blood cancers shows promising results alongside manageable side effects, according to the results of an international phase 1/2 clinical trial led by researchers at Washington University School of Medicine in St. Louis.
The clinical trial evaluated the safety and efficacy of an innovative CAR-T cell immunotherapy that is specifically designed to attack cancerous T cells. Participants in the trial had been diagnosed with rare cancers — T cell acute lymphoblastic leukemia or T cell lymphoblastic lymphoma — and had run out of treatment options after standard therapy proved ineffective for them. With the new immunotherapy, most of ...
Scientists identify diagnostic aid to determine risk of diabetic foot ulcer recurrence
2025-05-30
A research team funded by the National Institutes of Health (NIH) has identified a diagnostic aid that has the potential to accurately predict the recurrence of diabetic foot ulcers that appear to be fully healed. By measuring the skin’s barrier function through a process known as trans-epidermal water loss, or TEWL, scientists were able to determine which wounds were more likely to reopen. TEWL measurements are a major factor in burn care, where deep layers of the skin are often damaged. The findings suggest that full restoration of skin ...
NYU researchers devise method to identify ‘311’ underreporting of heat and hot water shortages
2025-05-30
Complaint lines such as New York City’s 311 let people report quality-of-life problems in their building or neighborhood, from excessive noise to illegal parking. But resident-generated data typically suffer from reporting bias, with some neighborhoods and addresses calling attention to problems at lower rates than others.
A team of New York University researchers has developed an automated modeling tool to help the New York City government estimate 311 under-reporting by building, neighborhood, and subpopulation. In a new study, published today [May 30] in Annals of Applied Statistics, the researchers describe a method that, using machine learning, can estimate the potential ...
