Assessment of the psychometric properties of the 17- and 6-item Hamilton Depression Rating Scales in major depressive disorder, bipolar depression and bipolar depression with mixed features.

Assessing therapeutic response in depression requires scales that adequately measure the core symptoms of depressive symptomatology. The main goal of this study was to assess the psychometric properties of the 17-item Hamilton Depression Rating Scale (HAM-D17) and the 6-item Hamilton Depression Rating Scale (HAM-D6) in patients with Major Depressive Disorder (MDD), bipolar depression and bipolar depression with mixed features. We conducted a reanalysis of a pragmatic clinical trial in an outpatient clinic for mood disorders that included eight weeks of follow-up.

Mental health economics: insights from Brazil.

Background: As the responsibility and demand on health care grows and resources do not increase at the same pace, the healthcare system has been forced to reconsider the benefits and costs of their actions, to ensure a rational and effective decision-making process regarding the adoption of interventions and allocation of resources. Cost-effectiveness (CE) studies represent one of the basic tools to achieve this goal.

Aims: To present the current state of Health Technology Assessment (HTA) and health economics in mental health in Brazil and its importance to the decision-making process.
