Official title: Prevalence and Risk Factors in Unipolar Depression Patients Without Remission After One Antidepressant Trial: PANTHER Study
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Unipolar major depression | Outpatients Individuals between 18 and 75 years old with a current episode of non-psychotic unipolar major depression that are treated with an antidepressant drug according to physician´s current and usual practice. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of patients with unipolar major depression that do not achieve remission after one antidepressant treatment.
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 drug treatment at an adequate dose. Variables will be compared between the patients that will achieve remission and those that do not.
Measured: 12 weeks
Secondary outcomes (2)
Clinical, therapeutic and socio-demographic characteristics of resistant depression patients and comparisson of them with the characteristics of the sample of depressed patients in remission.
Description of the clinical (Clinical history, episode features, BDI and HAM D17 scores), therapeutic (Type of drug, dose used, treatment period, adherence, presence and type of psychosocial therapy) and socio-demographic (age, gender, civil status, employment status, cohabitation, health insurance) characteristics of resistant depression patients and to compare them with the characteristics of the sample of depressed patients in remission.
Measured: 12 weeks
Comparison of the depression severity change assessed by the physician with the evaluation done by the patient
Comparison of the depression severity change assessed by the physician with the evaluation done by the patient by means of the BDI.
