Active clinical trials for "Depressive Disorder"

The goal of the study is to examine how cognitive behavioral therapy (CBT), a common treatment for adolescent depression, affects brain functioning. Depressed adolescents will complete an initial assessment consisting of an interview, questionnaires, computer tasks, and an EEG recording. EEG (electroencephalography) measures brain activity by recording the electrical activity along the scalp caused by the firing of neurons within the brain. They will then complete 12 sessions of cognitive behavioral therapy, which will be 50 minutes long and held once a week for 12 weeks. Before their third therapy session, participants will complete a computer task while EEG data are recorded. After completing the treatment, the participants will complete a final assessment, which will include questionnaires, computer tasks, and an EEG recording. They will also complete follow-up assessments over the phone 1, 3, and 6 months after completing the treatment. This study will also include healthy control participants. They will complete an initial assessment consisting of an interview, questionnaires, computer tasks, and an EEG recording. Three weeks later, they will return to complete a behavioral task while EEG data are recorded. Twelve weeks after the initial assessment, they will complete a final assessment, which will include questionnaires, computer tasks, and an EEG recording.

In this study, quetiapine XR or placebo will be administered orally for 6 weeks to major depressive disorder patients with lack of response to existing antidepressants, with the aim of evaluating the efficacy of quetiapine XR and dose-response in three quetiapine XR dose groups based on changes in Montgomery-Asberg Depression Rating Scale (MADRS) scores.

This study will determine the efficacy, safety, and tolerability of a 40 milligrams (mg) once-daily (QD) dose of LY2940094 for 8 weeks in participants with MDD.

Anxiety, Depression and Somatoform disorders are highly prevalent in primary care. Very often these conditions remain undiscovered and/or untreated. In order to ease this urgent health care problem in the future, the investigators conduct a cluster-randomized controlled trial, implementing a tandem working cooperation between a nurse practitioner (Counseling Assistant - CA) and a general practitioner (GP) on-site its own practise. The CA's task is to enhance the patients abilities to engage in a better self-management of their psychological symptoms and complaints, to enhance self-efficacy and empower the patients to tackle problems of daily living.

To compare the efficacy of brexpiprazole (flexible dose) with placebo as adjunctive therapy to an assigned open label antidepressant therapy (ADT) in the proposed subject population with MDD.

Primary Objective: - To evaluate the effects of two fixed doses of SSR149415 (250 mg bid and 100 mg bid) on hypothalamic-pituitary-adrenal axis function in patients with major depressive disorder. Secondary Objectives: To evaluate the tolerability and safety of SSR149415 in patients with major depressive disorder. To evaluate the efficacy of two fixed doses of SSR149415 compared to placebo in patients with major depressive disorder. To evaluate plasma concentrations of SSR149415.

The purpose of this study is to examine the effects of vilazodone for the treatment of depression in older adults.

This study will evaluate the effectiveness of a web-based behavioral activation(BA) treatment for depression by comparing it to in-person BA treatment in Soldiers and Veterans with Major and Minor Depressive Disorder. We will test the hypothesis that 8 sessions of in-home BA delivered via a webcam will be as safe and effective in reducing symptoms of hopelessness and depression as in-person BA treatment for depression.

This study will examine the effectiveness of an integrated treatment for adolescents who are depressed and use alcohol in an intensive outpatient setting in the community.

This study aims to compare the effectiveness of two telephone-based psychotherapy (Tel-PT) interventions for patients with mild to moderate depression. Both interventions consist of one personal session and weekly to bi-weekly 8-10 telephone sessions with a licensed cognitive-behavioral psychotherapist accompanied by the study of educational materials and the completion of regular monitoring questionnaires (total treatment duration: approximately 3 months). Patients are randomized into one of two conditions: Patients in the condition "Tel-PT including mail" additionally receive a motivating letter from their psychotherapist after each telephone session, while patients in the condition "Tel-PT without mail" receive no further interventions. Patients refusing to be randomized are to be assigned to the condition "Tel-PT without mail". This study takes place within a larger study evaluating a stepped care model for depression (01KQ1002B-TP7).
