PLISSIT
n. acronym for a model that is used in counseling clients about sexual problems. The model offers successive levels of communication or intervention: (a) Permission, in which the client is told it is acceptable to talk openly about a given sexual problem; (b) Limited Information, in which the client is given information limited to that directly relevant to his or her concern; (c) Specific Suggestions, in which actions to treat the problem are specified; and (d) Intensive Therapy, which may be required if the client has a complex problem (usually involving referral to another therapist). [developed in 1976 by U.S. psychologist Jack S. Annon (1929–2005)]
