Long-term and short-term relaxation training are two common forms of treatment for individuals experiencing problematic levels of anxiety  Yet studies show that on average, regardless of which form of treatment one receives, symptoms of anxiety decrease to a normal level within the short-term-training time period
Thus, for most people the generally more expensive long-term training is unwarranted
Recipients of long-term training are much less likely than recipients of short-term training to have recurrences of problematic levels of anxiety.
