Summary
Aggression is a risk in first-episode psychosis (FEP). Unemployment, substance misuse, and overactivity symptoms independently predict aggression in FEP patients.
Area of Science:
- Psychiatry
- Clinical Psychology
- Forensic Psychiatry
Background:
- Growing evidence links psychotic illness to increased aggression.
- Understanding aggression in early psychosis is crucial for intervention.
Purpose of the Study:
- To investigate the prevalence and predictors of aggressive acts in individuals experiencing their first episode of psychosis.
- To identify specific clinical and demographic factors associated with aggression in this population.
Main Methods:
- A cohort of 166 individuals with first-episode psychosis (FEP) was recruited from Nottingham, UK.
- Data were collected via clinical interviews, informant reports, and healthcare/forensic records over a 3-year period.
- Statistical analysis examined associations between aggression and various demographic/clinical variables.
Main Results:
- 33.1% of subjects exhibited aggressive acts during psychotic episodes.
- Serious aggression (weapon use, sexual assault, victim injury) occurred in 9.6% of subjects.
- Independent predictors of aggression included unemployment (OR=3.6), substance misuse (OR=3.1), and overactivity symptoms (OR=6.9).
Conclusions:
- Confirmed known demographic and clinical associations with aggression in FEP.
- No link was found between aggression and specific psychotic symptoms or diagnostic subtypes.
- Findings highlight the importance of addressing unemployment, substance misuse, and overactivity in managing aggression risk in FEP.

01:47Aggression
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 hire...
01:28Psychosis and Antipsychotic Drugs: Overview
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. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic symptoms in all...
01:26Psychosis: Goals of Pharmacotherapy
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. For...
01:29Psychological and Sociocultural Causes of Schizophrenia
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

01:28Conduct Disorder
Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
