Prodromal Questionnaire–Brief Version (PQ-B) Test - Description and methodology of the test
For readers who want to examine personal experiences in a structured way, the Prodromal Questionnaire-Brief Version (PQ-B) Test provides a focused self-report screen. It is intended for people reflecting on experiences that may be relevant to psychosis risk screening, especially when those experiences feel concerning, disruptive, or difficult to interpret. The result separates endorsed experiences from associated distress.
What This Assessment Explores
The questions cover perceptual changes, beliefs that feel unusual, suspiciousness, altered reality, thought-control concerns, intense thoughts, communication difficulty, and experiences others may not notice. Endorsement does not by itself indicate a disorder; the result adds context by showing whether experiences feel distressing or disruptive.
The displayed scales organize the result into two perspectives:
- Distress (0-105) assesses the severity of anxiety-related distress associated with prodromal symptoms. Its bands are Low (0-20) and Elevated (21-105).
- Symptoms (0-21) reflects the number of endorsed prodromal symptoms that may indicate risk for psychotic disorders and is used to screen for psychosis risk. Its bands are Low symptom count (0-5) and Elevated (screen positive) (6-21).
People may use the questionnaire to describe confusing experiences before discussing them with a qualified professional. It can clarify whether an experience feels neutral or disruptive.
Methodology and Scientific Basis
Each item first asks whether an experience has occurred, then asks how much fear, worry, anxiety, or practical difficulty it causes. Responses run from no experience to yes, with impact choices from not at all to definitely and an uncertainty option. This separates symptom endorsement from emotional weight.
Scoring follows the two displayed dimensions: the symptom dimension reflects endorsed experiences, while the distress dimension reflects associated severity ratings. The questionnaire reports the displayed ranges and bands, but no further point-allocation rule should be inferred.
The assessment is conceptually consistent with the Prodromal Questionnaire-Brief (PQ-B; Loewy et al., 2011), a shortened self-report screen evaluated against structured interviews, and with the earlier Prodromal Questionnaire. Elevated results may warrant additional consultation. Research on psychosis-like experiences supports giving distress weight because unusual experiences are not equally concerning.
As an online presentation, this PQ-B screening questionnaire is not documented as a standardized administration, and its scoring should not be treated as normed beyond the displayed reporting bands. Current context and response style can affect self-reported results, while endorsed experiences may require broader assessment.
