Could I have paranoid personality disorder?
Paranoid personality disorder is characterised by a long-standing pattern of mistrust and suspiciousness in which other people’s motives are often interpreted as malicious. Having some of these traits does not mean that someone has a personality disorder: DSM-5-TR requires an enduring, pervasive and clinically significant pattern.

DSM-5-TR
What are the DSM-5-TR features?
DSM-5-TR requires at least 4 of the 7 specific features, together with the general requirements for a personality disorder.
Specific criteria — paraphrased
Persistent unjustified doubts about the loyalty or trustworthiness of friends, partners or coworkers.
Reluctance to confide because information might be used against them.
Reading hidden humiliating, hostile or threatening meanings into benign remarks or events.
Holding long-standing grudges after perceived insults, injuries or slights.
Quickly feeling that character or reputation has been attacked and reacting angrily or counterattacking.
Repeated unjustified suspicions about a spouse’s or partner’s fidelity.
Diagnostic reference: DSM-5-TR (American Psychiatric Association, 2022). The wording above is intentionally concise and paraphrased.
The specific criteria are not sufficient on their own
- The pattern is enduring, inflexible and present across different contexts — not only during a crisis or in one particular relationship.
- It causes significant distress or impairment in social, occupational or other important areas of functioning.
- The pattern is stable over time and can be traced back at least to adolescence or early adulthood.
- It is not better explained by another mental disorder, a substance/medication effect or a medical condition.
Differential diagnosis
Paranoid personality disorder or delusional disorder?
In delusional disorder or another psychotic disorder, fixed delusional beliefs or other psychotic symptoms become central. In paranoid personality disorder, mistrust is pervasive and enduring, but reality testing is generally better preserved.
Clinical assessment
How is the diagnosis made?
Diagnosis is not based on a checklist or a single questionnaire. It requires clinical interviewing, review of the person’s long-term pattern and functional impact across settings, and differential diagnosis. Personality questionnaires and tests can support that assessment.

Personality disorders can share features and sometimes overlap, making differential diagnosis essential.
Are you wondering about your personality functioning?
An emotional and personality assessment can compare several hypotheses, clarify the overall pattern and avoid drawing conclusions from a few isolated traits.
