Abstract: The present research aims to verify whether the Drawing-and-Story Procedure is as valid and reliable for diagnosing major depressive disorder. The sample consisted of 60 adults, equally divided into two subgroups, that is to say, 30 patients diagnosed with moderate major depressive disorder and 30 subjects without pathology and with no history of depression. The instruments used were the Drawing-and-Story Procedure the Beck Depression Inventory (BDI) and Structured Clinical Interview for DSM-IV-TR, also known as SCID-NP, in order to avoid false-negative diagnoses and false positives the results of the Inventory (BDI) and to facilitate the differential diagnosis of major depressive disorder without co-morbidities. After drafting the participants into the sample and applying the three instruments to them, two judges were asked to evaluate the data of the Drawing-and-Story Procedure. The proceedings followed three stages: in the first, the evaluators separated protocols blindly while observing only the drawings of the Procedure. The second separated protocols while observing only the stories, and the third used patterns of analysis, 60 separate protocols taking into account both the drawings and stories. To this end, we use a total of 94 items taken from the literature that enable one to observe the condition in projective techniques. Following this analysis, it proceeded to the study of accuracy, and a third judge was also asked to evaluate the protocols. These analyzes judge should evaluate the protocols by assigning zero if the 94 items were missing and one if they were present. From this we compared the analysis of the same as follows: the validity study was correlated by the coefficient product-moment Pearson evaluations of judges between themselves and the judges with the external criterion. We also use the Chi-square, Fischer exact test and “T” test to verify that the items used in the study allowed the subjects to discriminate the two subgroups. In the accuracy study, the ratings of judges among themselves were compared through the Product-Moment coefficient of Pearson and raised in some cases the percentage of agreement between evaluations. The results indicated that judges were able to separate when the protocols were based on the stories and used the criteria defined by the literature. Furthermore, it observed that the items are mostly clear enough to allow accurate assessments. On the other hand, items that enable one to determine the populations are not many, which indicates the need for further studies with the instrument to be able to better characterize what are the criteria for demonstrating the depressed sample. However, the Drawing-and-Story Procedure was considered to be an instrument that could be used in cases where the hypothesis of Depressive Disorder is present.
