Summary
Individuals with violent content in attenuated psychotic symptoms (APS) show distinct clinical features. Adverse events like bullying may contribute to violent content in those at clinical high risk for psychosis.
Area of Science:
- Psychiatry
- Clinical Psychology
- Neuroscience
Background:
- The link between psychosis and violence often focuses on predicting violent acts.
- Violence within subthreshold positive symptoms remains an understudied area.
- Understanding this link is crucial for early intervention in psychosis.
Purpose of the Study:
- To explore violent content within attenuated psychotic symptoms (APS) in individuals at clinical high risk for psychosis (CHR).
- To identify clinical characteristics associated with violent content in APS.
- To investigate the role of adverse life events in the manifestation of violent content.
Main Methods:
- Analysis of comprehensive vignettes from 442 CHR individuals meeting criteria for attenuated psychotic symptom syndrome (APSS).
- Symptom content coded using the Content of Attenuated Positive Symptoms Codebook.
- Assessment of clinical symptoms, functioning, beliefs, and trauma history.
Main Results:
- Individuals with violent content exhibited significantly higher APS severity.
- Negative beliefs about self and others, and increased bullying experiences were associated with violent content.
- Self-directed violence was linked to higher APS, negative beliefs, and anxiety symptoms compared to no violent content.
Conclusions:
- Violent content in APS is associated with a distinct clinical profile in CHR individuals.
- Adverse life events, such as bullying, may influence the presence of violent content.
- Further research is needed to examine the relationship between violent content and actual behavior.

The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia.

01:47Aggression
30.6K
Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...

Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...
