“Depression is partly a nocebo effect, in the sense that it can be produced by negative exceptions about oneself and the world. The way in which these negative expectations develop and produce their negative effects provides some clues as to how they can be reversed. Expectancy effects grow, feeding upon themselves. One reason this happens is that our subjective states - our feelings, our moods and sensations - are in constant flux, changing from day to day and from moment to moment. The effects of these fluctuations depend on how we interpret them, and our interpretations depend on our beliefs and expectations. When we expect to feel worse, we tend to notice random small negative changes and interpret them as evidence that we are in fact getting worse. This interpretation makes us actually feel worse, and it strengthens the belief that we are getting worse, leading to a vicious cycle in which our expectations and negative emotions feed on each other, cascading into a full-blown depressive episode. .. Positive expectancies have the opposite effect. They can set in motion a begin cycle, in which random fluctuations in mood and well being are interpreted as evidence of treatment effectiveness, thereby instilling a further sense of hope and countering the feeling of hopelessness that are so central to clinical depression.”

“Like antidepressants, a substantial part of the benefit of psychotherapy depends on a placebo effect, or as Moerman calls it, the meaning response. At least part of the improvement that is produced by these treatments is due to the relationship between the therapist and the client and to the client's expectancy of getting better. That is a problem for antidepressant treatment. It is a problem because drugs are supposed to work because of their chemistry, not because of the psychological factors. But it is not a problem for psychotherapy. Psychotherapists are trained to provide a warm and caring environment in which therapeutic change can take place. Their intention is to replace the hopelessness of depression with a sense of hope and faith in the future. These tasks are part of the essence of psychotherapy. The fact that psychotherapy can mobilize the meaning response - and that it can do so without deception - is one of its strengths, no one of its weaknesses. Because hopelessness is a fundamental characteristic of depression, instilling hope is a specific treatment for it it. Invoking the meaning response is essential for the effective treatment of depression, and the best treatments are those that can do this most effectively and that can do without deception.”

“Our analyses of the FDA data showed relatively little difference between the effects of antidepressants and the effects of placebos. Indeed, the effects were so small that they did not qualify as clinically significant. The drug companies knew how small the effect of their medications were compared to placebos, and so did the FDA and other regulatory agencies. The companies found various ways to make the data seem more favorable to their products, and the FDA helped them keep their negative data secret. In fact, in some instances, the FDA urged the companies to keep negative data hidden, even when the companies wanted to reveal them. My colleagues and I hadn't really discovered anything new. We had merely revealed their 'dirty little secret'.”

“When people recover from depression via psychotherapy, their attributions about recovery are likely to be different than those of people who have been treated with medication. Psychotherapy is a learning experience. Improvement is not produced by an external substance, but by changes within the person. It is like learning to read, write or ride a bicycle. Once you have learned, the skills stays with you. People no not become illiterate after they graduate from school, and if they get rusty at riding a bicycle, the skill can be acquired with relatively little practice. Furthermore, part of what a person might learn in therapy is to expect downturns in mood and to interpret them as a normal part of their life, rather than as an indication of an underlying disorder. This understanding, along with the skills that the person has learned for coping with negative moods and situations, can help to prevent a depressive relapse.”

“For people who are depressed, and especially for those who do not receive enough benefit from medication of for whom the side effects of antidepressants are troubling, the fact that placebos can duplicate much of the effects of antidepressants should be taken as good news. It means that there are other ways of alleviating depression. As we have seen, treatments like psychotherapy and physical exercise are at least as effective as antidepressant drugs and more effective than placebos. In particular, CBT has been shown to lower the risk of relapsing into depression for years after treatment has ended, making it particularly cost effective.”

“Psychotherapy works for the treatment of depression, and the benefits are substantial. In head-to-head comparisons, in which the short-term effects of psychotherapy and antidepressants are pitted against each other, psychotherapy works as well as medication. This is true regardless of how depressed the person is to begin with. Psychotherapy looks even better when its long-term effectiveness is assessed. Formerly depressed patients are far more likely to relapse and become depressed again after treatment with antidepressants than they are after psychotherapy. As a result, psychotherapy is significantly more effective than medication when measured some time after treatment has ended, and the more time that has passed since the end of treatment, the larger the difference between drugs and psychotherapy.”

“Eventually it became clear that our emotions, attitudes, and thoughts profoundly affect our bodies, sometimes to the degree of life or death. Soon mind-body effects were recognized to have positive as well as negative impacts on the body. This realization came largely from research on the placebo effect—the beneficial results of suggestion, expectation, and positive thinking.”
