paranoid personality disorder
in DSM–IV–TR, a personality disorder characterized by (a) pervasive, unwarranted suspiciousness and distrust (e.g., expectation of trickery or harm, overconcern with hidden motives and meanings); (b) hypersensitivity (e.g., being easily slighted or offended, readiness to counterattack); and (c) restricted affectivity (e.g., emotional coldness, no true sense of humor). The diagnosis has been retained in DSM–5.
