Ethical questions about the manipulative, deceptive nature of paradoxical interventions were addressed. Perceptions of the therapist and of the acceptability of paradoxical vs. nonparadoxical directives were examined using simulation methodology. Participants, 97 undergraduates, took part in a semester-long family simulation of excessive family arguing associated with a rebellious adolescent daughter. Before experimental manipulation, the "families" participated in 4 role-playing exercises and attended a family therapy session. They then received a letter from their therapist containing 1 of the 2 types of directives and, subsequently, responded to the dependent measures. Results indicated (a) paradoxical directives did not negatively influence perceptions of therapist attractiveness, expertness, or trustworthiness; (b) they were judged less acceptable than nonparadoxical directives, although neither was deemed unacceptable.
