Prospective Bidirectional Associations Between Core Schemas, Attenuated Psychotic Symptoms, and Functioning in Youth at Clinical High Risk for Psychosis
This study of 578 clinical high-risk youth demonstrates that maladaptive core schemas prospectively predict worsening psychotic symptoms and functional decline, while positive schemas predict improvement, highlighting schemas as bidirectional, modifiable treatment targets that extend cognitive models of psychosis.

For many young people, the years leading up to adulthood can be a time of intense internal confusion, where the line between what is real and what is imagined begins to blur. Some experience this as a warning sign for a serious mental health condition known as psychosis, a state where a person loses contact with reality. Scientists have long suspected that the way these individuals think about themselves and the world around them plays a crucial role in how these symptoms develop. They call these deep-seated beliefs "core schemas." Think of these as the mental lenses through which a person views every new experience; if the lens is cracked or dark, a neutral event might look threatening, while a bright lens might make the same event feel safe. Understanding how these mental lenses change over time, and whether they cause symptoms to worsen or improve, is vital. If researchers can prove that shifting these beliefs can change the course of the illness, it could open the door to new, more effective ways to help young people before a full-blown crisis occurs.
A team of researchers recently set out to test this idea by watching a large group of young people who were already showing early warning signs of psychosis. They followed 578 individuals across five different check-ins over a period of two years. At each visit, the participants answered questions about their beliefs regarding themselves and other people, as well as how they were feeling and functioning in their daily lives. The researchers were looking for a specific pattern: did a change in a person's beliefs happen first, followed by a change in their symptoms, or did the symptoms come first and change the beliefs? By using advanced statistical methods to track these shifts over time, they could see which way the influence flowed.
The study revealed that these mental lenses are indeed dynamic and powerful. The researchers found that negative beliefs about other people—such as thinking others are hostile or untrustworthy—consistently predicted a worsening of symptoms and a decline in how well a person could function socially and at work or school. When a young person's view of others became more negative, they were more likely to experience increased paranoia, unusual thoughts, and social withdrawal in the months that followed. This suggests that these negative beliefs are not just a side effect of being unwell, but an active driver that pushes the condition forward.
Interestingly, the relationship between beliefs and symptoms was not always a one-way street. The researchers discovered a unique, two-way loop specifically regarding suspiciousness. When a person felt suspicious of others, it made them more likely to develop negative beliefs about people in general. In turn, holding those negative beliefs made them feel even more suspicious later on. This creates a self-reinforcing cycle where the fear of others and the belief that others are dangerous feed into each other, tightening the grip of the symptom. However, this cycle was not the only story. The study also found that positive beliefs about oneself and others acted as a shield. When young people held onto positive views, they were less likely to develop suspicious thoughts or negative symptoms, and they tended to maintain better social and occupational functioning.
There were some surprising exceptions that challenged simple assumptions. While positive beliefs usually protected against symptoms, they were linked to an increase in grandiose ideas, where a person might feel they have special powers or a unique destiny. This suggests that grandiosity might stem from an inflated sense of self rather than a fear of others, pointing to a different path in how these symptoms form. The researchers also noted that while depression often travels alongside these negative beliefs, the link between negative beliefs about others and worsening symptoms remained strong even when accounting for low mood. This indicates that the belief that "people are out to get me" is a distinct and powerful force in its own right, separate from general sadness.
The findings offer a clearer map of the terrain for clinicians and families. They suggest that treating these young people might require more than just managing the symptoms as they appear; it may be essential to actively work on changing the underlying beliefs about the self and others. By helping a person shift from seeing the world as a hostile place to seeing it as manageable, or by strengthening their positive self-view, it might be possible to interrupt the cycle of decline. While the study does not prove that changing beliefs will cure the condition, it provides strong evidence that these beliefs are a moving target that influences the future of the illness, offering a promising new direction for therapy and hope for those navigating this difficult period.
