Abstract
Background: Several studies have reported a strong relationship between distorted thoughts and Major Depressive Disorder, but there is a lack of tests that match these needs. Objectives: to investigate the psychometric proprieties of Depression Thoughts Scale – EPD with depressive symptoms scales. Method: a total of 367 subjects divided into non-depressed and depressed groups were assessed. The first group contained 338 (92.1%) subjects classified as having no reported diagnosis of depression, while the remaining subjects (n=29) comprised the second group containing subjects with clinically and SCID-confirmed diagnosis of depression. Data collection was performed by applying instruments assessing depressive symptoms including the Baptista Depression Scale -EBADEP-A and Hamilton Rating Scale for Depression -HAM-D. Data was collected individually in the clinical group and collectively in the non-clinical group. Results: the data indicated that the EPD had moderate correlation with the HAMD (p= 0.001) and strong with EBADEP A (p=0.001), where depressives exhibited a greater number of distorted thoughts. Conclusion: the EPD proved a potentially useful tool for helping clinicians identify depressive thoughts, functioning as a complement to access specifically the cognitive factors related with depression.
Highlights
Major Depressive Disorder (MDD) is a highly prevalent, debilitating and multi-determinant condition
Depression constitutes a disorder with multi-determinate causes that affects people worldwide whose incidence has risen in recent years
[2] developing techniques to help screen for cases of depression is important. This need prompted the present study whose main focus was to determine the association between the EPD and the EBADEP -A in both a clinical group, characterized by subjects with SCID-CV-confirmed diagnosis of depression, and in a group reporting no depression diagnosis, and between the EPD and the Hamilton Rating Scale for Depression (HAM-D) in the clinical group only, in order to verify evidence of validity based on the relationship with other variables and group criteria using the EPD
Summary
Major Depressive Disorder (MDD) is a highly prevalent, debilitating and multi-determinant condition. Studies comparing MDD against patients with other mental disorders and control groups have shown that the cognitive profile of depressed subjects differs significantly, indicating that perceptions of self, others and the world were more pessimistic where the greater the negativity the worse the depressive symptoms [5,7,10,11,12,13]. Several studies have reported a strong relationship between distorted thoughts and Major Depressive Disorder, but there is a lack of tests that match these needs. Results: the data indicated that the EPD had moderate correlation with the HAMD (p= 0.001) and strong with EBADEP A (p=0.001), where depressives exhibited a greater number of distorted thoughts. Conclusion: the EPD proved a potentially useful tool for helping clinicians identify depressive thoughts, functioning as a complement to access the cognitive factors related with depression
