Completed

• Conditions: Non-psychotic Unipolar Major Depression

• Registration Number: NCT01887639
• Lead Sponsor: AstraZeneca

Brief Summary

A non interventional, descriptive, longitudinal cohort study is designed, trying to obtain local data about the prevalence of non remitted depressed patients after an antidepressant treatment, and to get information about sociodemographic and clinical characteristics of these patients as well as features of their treatments and compare them with those of the patients that achieve remission.

Detailed Description

A non interventional, descriptive, longitudinal cohort study is designed, trying to obtain local data about the prevalence of non remitted depressed patients after an antidepressant treatment, and to get information about sociodemographic and clinical characteristics of these patients as well as features of their treatments and compare them with those of the patients that achieve remission. Also the effect of patient´s expectation in the treatment outcome will be examined.

Non psychotic depressed patients that are initiating an antidepressant treatment will be recruited. Socio demographic and clinical features will be recorded as well as their expectations before the treatment. Severity of depression and treatment characteristics will be recorded after 4 to 8 weeks of drug treatment at an adequate dose. Variables will be compared between the patients that will achieve remission and those that do not.
