Paranoid disorder

A pervasive distrust and suspiciousness of others such that their motives are interpreted as malevolent, beginning by early adulthood and present in a variety of contexts, as indicated by four (or more) of the following:

• suspects, without sufficient basis, that others are exploiting, harming, or deceiving him or her

• is preoccupied with unjustified doubts about the loyalty or trustworthiness of friends or associates

• is reluctant to confide in others because of unwarranted fear that the information will be used maliciously against him or her

• reads hidden demeaning or threatening meanings into benign remarks or events

• persistently bears grudges, i.e., is unforgiving of insults, injuries, or slights

• perceives attacks on his or her character or reputation that are not apparent to others and is quick to react angrily or to counterattack

• has recurrent suspicions, without justification, regarding fidelity of spouse or sexual partner
