CLEAR ANSWERS TO COMMON QUESTIONS

Frequently Asked Questions

What does this questionnaire measure?

It measures the frequency and severity of suspicious thoughts, including ideas of reference and fears of being harmed or targeted. It captures these experiences over a recent time frame.

What are ideas of reference and persecutory ideas?

Ideas of reference involve interpreting neutral events as being directed at oneself (for example, thinking others are talking about oneself). Persecutory ideas involve concern that others intend harm, interference, or deliberate targeting.

How long does it take to complete and how many items are included?

Completion typically takes about 4 minutes. The questionnaire includes 18 statements.

How should items be answered?

Select the response option that best matches how often each statement has been true recently. Answer each item based on typical experiences rather than unusual one-time events.

How should results be interpreted?

Scores provide separate indicators for ideas of reference and persecutory ideas, along with an overall profile. Results are screening information and should be interpreted alongside other clinical or research data.

WHAT THE TEST MEASURES

About This Assessment

Revised Green et al. Paranoid Thoughts Scale (R-GPTS) Test - Symptoms and Signs

paranoia psychopathology

This measure assesses the severity and frequency of paranoid thoughts, including ideas of reference and persecutory ideation. The Revised Green et al. Paranoid Thoughts Scale (R-GPTS) is intended for use in clinical or research contexts as a brief self-report screening of these experiences.

The instrument contains 18 items and typically takes about 4 minutes to complete. Responses are used to summarize an individual’s endorsement of suspiciousness-related beliefs across the two primary content areas, supporting efficient characterization of symptom burden and comparison across groups. As described by psytests.org (2024), the Revised Green et al. Paranoid Thoughts Scale (R-GPTS) is not a diagnostic tool and should be interpreted alongside clinical interview findings and other relevant assessment data.
