The effects of an antidepressant medication on reducing symptoms of Major Depressive Disorders in males and females, ages 18 – 25, who have been diagnosed with Major Depressive Disorders and live in Pinellas County, Florida. Major Depressive Disorders is based on the patient’s self-reported experiences, behavior reported by relatives or friends, and a mental status examination. With the variety of antidepressant medications and the ranges of doses, it becomes difficult to give a clear explanation of an operational definition for antidepressants.

Once the interview process is complete each individual will be given a Mental Status Examination. At the conclusion of the Mental Status examination we will then determine the level of each individual’s Major Depressive Disorder and prescribe 25 males and 25 female’s antidepressant medication for the next twelve weeks. The remaining 25 males and 25 females will all receive a placebo for the next twelve weeks; think they are taking an antidepressant. At the end of weeks 4, 8 and 12 all individuals will have the Mental Status Examination re-administered. The parents of each individual will go through the same interview process before the study, asking the same questions about their child’s behavior over the last twelve weeks. The goal of the experiment is to see if antidepressant (independent variable) will reduce...
