To determine whether hypnosis is more effective than conventional interviewing to find traumatic life events in patients with fibromyalgia, we carried out a within-subject experimental design with complete intragroup counterbalancing. Thirty-two women under care in a public primary care center gave 2 identical interviews, with an interval of 3 months, in which the occurrence of traumatic life events was explored, once in a state of wakefulness and once in a state of hypnosis. The state of consciousness was evaluated using 3 measures: bispectral index, skin conductance level, and pain intensity. In the hypnotic state, the patients expressed 9.8 times more traumatic life events than in the waking state, a statistically significant difference with a large effect size.
