Paranoid Personality Disorder
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
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.
