This paper aims to investigate the psychometric proprieties reliability and validity of these scales in a Brazilian sample, and to compare responses in bipolar and unipolar patients.

Furthermore, some symptoms can be confounded with physical disorders, such as sleep disturbances and changes in weight or libido; these complicating factors facilitate underdiagnosis and confusion with bipolar disorder [ 3 – 7 ].

Test-retest methodology was employed using a two-day interval between interviews. The prospective week study consisted in a sample of type II BD patients Moreover, is important to highlight that the MADRS and HAM-D have a number of particularities that should be considered by the clinician, including the number of constituent items and the distribution of symptoms.
