The use of hypnosis in a pediatric setting has the potential for yielding effective results. Obstacles to its use are inappropriate training of psychologists in pediatric psychology, resistance to hypnosis from the pediatricians and mental health professionals, fragmented communication, and constant demand for space and time. Success of hypnosis for the individual patient in a clinical situation depends on strong motivation and expectations, a positive relationship with the therapist, and trance ability. Successful use of hypnosis in pediatric care requires a strong desire for using hypnosis, positive collaboration with the pediatricians, and credibility in using hypnosis. In one pediatric hospital setting, hypnosis was used in about five percent of the referrals. Four symptom areas are particularly conducive to the use of hypnosis: (1) pain and discomfort; (2) anxiety and phobic disorders; (3) undesirable habits; and (4) other physical symptoms. Five signs of established credibility include earlier referrals, clearer professional communication, more requests for educational experiences, less checking out of the psychologists, and more informal inquiries regarding hypnosis. Maintaining credibility can be helped by staying visible, continuing educational efforts with the pediatricians, keeping abreast of current demand in subspecialty areas, facilitating the pediatrician's preparation of patients for referral, and preventing psychologist burnout by keeping responsibility in line with interests. Maintaining autonomy as much as possible seems essential for the effective use of hypnosis. (ABL)
