Brief Description
The Yale PRIME Early Psychosis Screening Test (Yale-PRIME) assesses an individual's risk of developing a psychotic disorder. The Yale-PRIME looks at "prodromal" symptoms of psychosis: symptoms that often occur before a full-blown psychosis clinical presentation. The PRIME screening test was developed based on a structured interview known as the SIPS (Structured Interview for Prodromal Syndromes). Respondents rate how much they related to the symptoms listed (e.g., “I think that I have felt that there are odd or unusual things going on that I can’t explain”) on a scale from “Definitely disagree” to “Definitely agree.”

Summary of Scoring and Interpretations
The Yale-PRIME contains 12 questions scored on a 7-point Likert scale with values from 0 ("Definitely disagree") to 6 ("Definitely agree"). A positive screen can be either one or more scores of "6" or three or more scores of "5." Note: a positive screen does not confirm a diagnosis and further evaluation is recommended.
Score | Interpretation |
6 on any question | Positive screening result; consider further assessment. |
5 on three or more questions | Positive screening result; consider further assessment. |
Blueprint Adjustments
Blueprint provides a total score that consists of summing all questions, with higher scores indicating greater prodromal psychotic experiences. However, clinicians may review the assessment results and examine each question’s response to determine if it’s a positive screen using the scoring criteria above.
Clinical Considerations
3-5 minutes to complete
Research on the Yale-PRIME is limited because it is based on the structured interview, the Structural Interview for Prodromal Symptoms.
As noted, a positive screening does not equate to a diagnosis and further diagnostic evaluation is recommended.
