I have stated that the models of abnormality that were used in this study were the cognitive behavior and model based on the IVs of the CBT and the antidepressants. the question is what other model could have been tested and how the researchers could have used it? It has to be short and to the point. and I've been given the hint that it should be the model that best deals with depression, but I'm at a loss because phylodynamic seems dumb in a 4 month study as does socio economic. and humanistic doesn't use MMPI

A team of researchers wanted to determine the effectiveness of cognitive behavioral therapy on depression. They contacted three mental health centers, one in Chicago, one in Boston, and one in Seattle. The mental health center in Chicago had 654 patients of whom 110 were diagnosed with major depression. The mental health center in Boston had 538 clients of whom 78 were diagnosed with major depression. The center in Seattle had 711 clients of whom 97 were diagnosed with major depression. Thus, there were a total of 285 clients among the three mental health centers who were diagnosed with major depression.

All participants were given the MMPI-2-RF and the Beck Depression Inventory. The researchers choose only those who scored at or below the 20th percentile on the Demoralization and Low Positive Emotion subscales of the MMPI-2-RF and at or below the 30th percentile on the Beck Depression Inventory.

In each city, the researchers put them into three groups: (1) fifteen (15) participants received an antidepressant only, (2) fifteen (15) received cognitive behavioral therapy (CBT) only, and (3) fifteen (15) received no treatmentthey were on the waiting list to be seen by a therapist. Halfway through the study, the mental health center in Chicago got a new director who chose to withdraw her center from the study. At the end of four months all the remaining participants were again given the MMPI-2-RF and the Beck Depression Inventory. The results showed that those who took the antidepressant only scored significantly lower on the Demoralization and Low Positive Emotion subscales of the MMPI-2-RF and scored lower on the Beck Depression Inventory. Those who received the CBT only scored significantly lower on the Demoralization and Low Positive Emotion subscales of the MMPI-2-RF and scored lower on the Beck Depression Inventory. In fact, both groups improved similarly. The third group (on the waiting list) showed no improvement on their scores on the Demoralization and Low Positive Emotion subscales of the MMPI-2-RF and showed no improvement on the Beck Depression Inventory.

The researchers concluded that CBT was just as effective as antidepressant medication for anyone who has major depression.
