Psychosis & Schizophrenia Self-Test: Free 3-Minute Screening is based on Deenz Psychotic Rating Scale (DPRS-45), a 25-item self-assessment developed by DM Dar. Based on 41 anonymized responses collected through the Drdeenz Research Project , the Deenz Psychotic Rating Scale (DPRS-45) assessment demonstrated excellent internal consistency reliability (Cronbach's α = 0.956) . Drdeenz provides this interactive version for educational, research, and self-exploration purposes only. Results are not diagnostic and do not replace professional evaluation.

Deenz Psychotic Rating Scale (DPRS-45)

Background

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.

Procedure

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.

Participation

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.

Scoring & Interpretation

The DPRS-45 contains 45 items divided across nine dimensions. Each item is rated on a five-point agreement scale. Scores are calculated for each dimension as well as an overall psychosis-spectrum index.

Higher scores indicate greater endorsement of psychosis-related experiences or traits. Results are intended to identify patterns and tendencies rather than determine the presence of a psychiatric disorder.

Dimension scores are converted to a 0–100 scale for interpretation.

Overall interpretation ranges:

• Minimal (0–20)
• Mild (21–40)
• Moderate (41–60)
• High (61–80)
• Very High (81–100)

Frequently mentioned: Good

Paranoia

Screener Construction There are 5- 8 questions that overlap with Autism Spectrum so this screener may not be specific enough. With ASD and psychosis they say providers need to included behavioural correlates to comparatively ascertain if psychosis is really prominent in the period of assessment or just behavioural outcomes of ASD. Overall its good indicator of psychosis trend and good to use with your PCP as a starting point for more convo. The polar graph is a nice touch. Overall Impression The screener did sync with my thoughts that I'm on the borderlands of psychosis (if psychosis is actually real at all or just a statement of North American culture or sub-culture). Not better than chance although specific traits may be predictive. People should be aware of cultural nuances. People could actually be truly paranoid in Iran, China or Israel and magnitude and context should be considered. I see too many foreigners in psych wards and wonder. Paranoia to a certain extent I think is normal in our society and many people have it even if they don't disclose it.

I fail to see where this test checks for symptoms that can't be explained by chronic anxiety and depression
