On anxiety and stress,
Perspective is provided by comparing self-hypnosis training with other treatment options. CBT has proven effective in reducing anxiety, but may often require a larger number of sessions to accomplish the objective. Medication treatment is widely used, but clearly has limitations. A review of the research on 13 anxiety medications found that psychopharmacologic treatment was superior to a placebo less than half of the time (48%), while, as noted previously, hypnosis has been documented as superior to placebo and at least equivalent to medication in numerous studies of procedural or surgical anxiety.
