Thoughts are considered by Cognitive Therapy as an essential part for depression treatment and consider that the negative perception of yourself, the others and future interfere directly in their cognitive vulnerability. This way, the present study aims to present the item construction process, content evaluation and factor analysis of the Depressive Thoughts Scale - EPD, based on cognitive triad. Participated of the study 639 subjects with and without depression diagnosis, aged 18 to 50 of both sexes. Applications were performed individually for those with confirmed diagnostic of depression and collectively for others. It was found that EPD items were able to differentiate the groups, indicating those diagnosed with depression as those with higher depression thoughts. After factor analysis, scale was reduced to 34 items, with five interpretable factors and not randomized, named as Low self esteem, Interpersonal relationship, Self appreciation, Negative expectations and Disarrangement social and dissatisfaction. The reability indices pointed the need for further studies in order to investigate the scale configuration. These results indicate adequate psychometric properties for the scale, and serve the purpose of arousing further studies to find evidence of validity and reliability.
