Paranoid personality disorder (PDD) is characterized by a pervasive pattern of distrust and suspicion, beginning in early adulthood and occurring in a variety of settings (no specific paranoid delusions).


  • Believe they are being exploited and deceived by others

  • Interpret benign comments and events as threats, and react angrily

  • Bear grudges

  • Question the loyalty of partners without justification

Other characteristics include:

  • Oversensitivity to perceived criticism

  • Tendency towards aggression or defensiveness in response to perceived attacks

  • Reluctance to confide in others

PDD often results in social isolation and strained interpersonal relationships, and can make it difficult to establish rapport and a therapeutic alliance with these patients.



Unlike delusional disorder, where delusions are specific, fixed, and unshakeable (held with delusional intensity), individuals with PPD have generalized suspicion without distinct delusions.


Take a non-defensive stance with these patients, and carefully explain things to them.
