What are the five domains involved in schizophrenia spectrum and other psychotic disorders?

The five domains involved in schizophrenia spectrum and other psychotic disorders are delusions, hallucinations, disorganized thinking, abnormal motor behavior, and negative symptoms. These domains capture the core features that clinicians assess to diagnose and determine the severity of schizophrenia and related disorders.

Delusions refer to strong beliefs that are not based in reality, such as paranoia or grandiosity. Hallucinations involve sensory experiences without an external stimulus, most commonly auditory hallucinations where individuals might hear voices. Disorganized thinking, often evidenced through incoherent speech or difficulty concentrating, impacts the individual's ability to process and communicate. Abnormal motor behavior can range from agitated movements to catatonia, while negative symptoms encompass a decrease in emotional expression, motivation, or ability to socialize.

These domains are important in understanding the complexities of psychotic disorders and guide the treatment approaches that clinicians may take. The other choices present different sets of skills or domains that do not pertain to the specific criteria used to diagnose schizophrenia and related disorders, focusing instead on areas such as cognitive functions, social skills, or emotional regulation, which are not central to the schizophrenia spectrum.
