Paranoid personality disorder

Paranoid personality disorder is a longstanding pattern of pervasive distrust and suspiciousness in which others’ motives are often interpreted as harmful or threatening.

DSM-5-TR: The American Psychiatric Association’s diagnostic manual for mental disorders. Its criteria describe the persistent suspicion and mistrust that define this disorder.
Schizotypal personality disorder: A personality disorder involving social deficits, eccentric behavior, and unusual beliefs or perceptions. Both can involve suspicion, but schizotypal disorder also features eccentricity and perceptual distortions.
Psychotherapy: The use of psychological methods to treat mental and emotional difficulties. Treatment commonly focuses on distress and functioning while building a reliable therapeutic relationship.
Personality disorder diagnosis: The clinical process of identifying enduring personality patterns that cause impairment or distress. Assessment must distinguish a disorder from culturally shaped caution or reasonable responses to danger.
ICD-11: The World Health Organization’s international classification of diseases. Its dimensional approach classifies personality disorder severity and trait domains rather than this specific subtype.
Delusional disorder: A psychotic disorder characterized by one or more persistent delusions. Fixed persecutory beliefs distinguish delusional disorder from the broader suspicious style of this personality disorder.
Cognitive behavioral therapy: A structured psychotherapy that examines links among thoughts, emotions, and behavior. It can help examine interpretations and coping patterns without requiring immediate trust.
Dimensional model of personality disorders: An approach that describes personality pathology by severity and trait dimensions rather than fixed categories. Dimensional systems raise questions about whether paranoid traits form a distinct diagnostic category.
Persecutory delusion: A fixed false belief that others intend to harm, deceive, or persecute someone. Suspicious interpretations can resemble persecution, but this disorder does not require delusions.
Post-traumatic stress disorder: A disorder involving persistent symptoms after exposure to traumatic events. Trauma-related hypervigilance can resemble pervasive mistrust but is linked to traumatic exposure.
