Hypnotic responsivity and the treatment of flying phobia.

Systematic follow-up data are reported for 178 consecutive flying phobia patients treated with a single 45-minute session involving hypnosis and a problem restructuring strategy. One hundred fifty-eight (89%) of the patients completed follow-up questionnaires between six months and ten and one half years after treatment. Results showed that hypnotizable patients were over two and one half times more likely to report some positive treatment impact than those who were found to be nonhypnotizable on the Hypnotic Induction Profile. In addition, the patients' previous experiences with psychotherapy were found to be significantly associated with treatment outcome. The clinical implications of these findings are discussed.
