A second assumption called into question by the article, termed the "Dodo bird verdict," is that all psychotherapy approaches are equivalent (Rosenzweig  quoted this character from Alice's Adventures in Wonderland , who declares after a race that "everybody has won, and all must have prizes"). Many psychotherapists believe that specific techniques are less important than are nonspecific factors such as the therapeutic relationship. Areán and colleagues note that both problem-solving therapy and supportive therapy reduced depressive symptoms over the first 6 weeks of treatment and suggest that factors common to these therapies, such as empathy and instilling hope, may have beneficial effects for depressed older adults with executive dysfunction. At weeks 9 and 12, however, problem-solving therapy resulted in significantly greater response and remission rates than did supportive therapy, with one additional remission for every 4.5 patients treated. One proposed explanation is that the specific techniques employed in problem-solving therapy, such as setting goals, brainstorming and evaluating strategies to achieve those goals, creating action plans, and evaluating their effectiveness, have value beyond psychological support for reducing depression in individuals who have poor problem-solving skills because of their cognitive and affective disorder. According to this explanation, over the second half of treatment, the patients receiving problem-solving therapy engaged in additional practice to consolidate their problem-solving skills and as a result, continued to experience a decline in their depressive symptoms.
