Deenz Psychotic Rating Scale (DPRS-45)

Psychosis Test is an interactive version of the Deenz Psychotic Rating Scale (DPRS-45), a self-assessment designed to measure psychosis-spectrum tendencies. The questionnaire consists of 45 statements that assess patterns of perception, thinking, behavior, emotional functioning, and social experiences associated with psychotic-spectrum traits.

Psychosis refers to a mental state in which a person experiences difficulty distinguishing between what is real and what is not. Individuals experiencing psychosis may hear voices, see things others do not see, hold unusual beliefs, or experience disturbances in thinking and behavior. Psychosis itself is not a disorder but a symptom that may occur in several mental health conditions including schizophrenia spectrum disorders, bipolar disorder, severe depression, neurological conditions, substance use disorders, and other psychiatric conditions.

The Deenz Psychotic Rating Scale (DPRS-45) was developed to assess psychosis-related tendencies on a dimensional spectrum rather than using a simple present-or-absent approach. Modern psychological research increasingly recognizes that psychotic-like experiences may occur in the general population at varying levels of intensity and frequency. Measuring these experiences dimensionally provides a more comprehensive understanding of individual differences.

The scale evaluates nine major domains commonly associated with psychosis-spectrum symptoms: Hallucinations, Delusions, Disorganization, Catatonia, Apathy, Anhedonia, Paranoia, Alogia, and Agitation. These domains include both positive symptoms (such as hallucinations and delusions) and negative symptoms (such as apathy, anhedonia, and alogia), as well as cognitive and behavioral characteristics.

This assessment is intended solely for educational and self-reflection purposes. It is not designed to diagnose schizophrenia, psychotic disorders, or any other mental health condition. Only a qualified mental health professional can provide a clinical diagnosis.

The assessment consists of 45 statements and typically requires 6–10 minutes to complete. Participants respond to statements related to perceptions, beliefs, social experiences, emotions, motivation, speech patterns, and behavior. There are no right or wrong answers.

This self-assessment is intended for adults and older adolescents interested in understanding psychosis-spectrum traits and experiences. Participation is completely anonymous. No personally identifying information is collected or stored.

The DPRS-45 contains 45 items divided across nine dimensions. Each item is rated on a five-point agreement scale (0 = Strongly Disagree to 4 = Strongly Agree). Total raw scores are calculated by summing all responses, with the total score ranging from 0 to 180. Higher scores represent a greater intensity or frequency of psychosis-spectrum traits. Scores are distributed across nine distinct clinical subscales (Hallucinations, Delusions, Disorganization, Catatonia, Apathy, Anhedonia, Paranoia, Alogia, and Agitation), which are standardized to a 0–100 scale for comparative profiling.
