The purpose of this research study is to learn whether specific types of brain imaging and psychological testing can predict how much benefit patients with depression will receive from a well-studied psychotherapy for depression, called cognitive behavioral therapy (CBT), and how the brain imaging and psychological tests change with treatment. We will also be comparing brain scans from this study between individuals suffering from depression and volunteers without depression.
This study offers 14 sessions of one-on-one cognitive-behavioral therapy (CBT) over twelve weeks, administered by an experienced doctoral-level psychologist or psychiatrist.

Cognitive Behavioral Therapy
Depressed individuals who enroll in this study will receive 14 sessions of cognitive behavioral therapy provided by an experienced psychiatrist or psychologist over 12 weeks (twice-a-week for the first two weeks, and weekly after that).

14 sessions of individual psychotherapy (cognitive behavioral therapy) for depression over 12 weeks
- Remitters as Assessed by Post-treatment Beck Depression Inventory Less Than or Equal to 10 [ Time Frame: 12 weeks ]The primary outcome of this study is remission from depression at the conclusion of 12 weeks of cognitive behavioral therapy for depression. This will be assessed using the Beck Depression Inventory, a self-report questionnaire of symptoms of depression that will be administered at every treatment visit. Remission is defined by a final Beck Depression Inventory score less than or equal to 10.
- Post-Treatment Beck Depression Inventory [ Time Frame: Post-Treatment, up to 12 weeks ]
The Beck Depression Inventory is a self-report measure of depression severity that is a well-characterized scale with excellent psychometric properties and is frequently used in research studies of depression.
The scale measures symptoms related to sadness, pessimism, past failure, loss of pleasure, guilty feelings, punishment feelings, self-dislike, self-criticalness, suicidal thoughts or wishes, crying, agitation, loss of interest, indecisiveness, worthlessness, loss of energy, changes in sleeping pattern, irritability, changes in appetite, concentration difficulty, tiredness or fatigue, and loss of interest in sex.
We report the total score on the BDI, which has a range of 0 to 63. Higher values represent greater severity of depression. The following score interpretations are provided in the scale's manual:
0-9 minimal depression 10-18 mild depression 19-29 moderate depression 30-63 severe depression
- Final Score on the Hamilton Depression Rating Scale [ Time Frame: Post-Treatment, up to 12 weeks ]
Final score on the Hamilton Depression Rating Scale (HDRS) was calculated for 37 patients who were treated with Cognitive Behavioral Therapy.
The 17-item HDRS is a clinician-administered scale that quantifies depression severity, and includes items assessing mood, suicidal thinking, insomnia, feelings of guilt, work and activities, somatic symptoms, and insight. It is a well-characterized scale with excellent psychometric properties. The total score is the sum of the individual scores of the 17 scale items. Higher scores indicate greater depression severity. When using this outcome measure, we covary for baseline HDRS scores. Published norms for interpretation of the 17-item HDRS use a different version of the scale with a total possible score of 52, and are listed below. Interpretation is comparable (but not identical) with the 17-item HDRS version used in this study, which has a maximum score is 51.
None: 0-7 Mild: 8-13 Moderate: 14-19 Severe: 20-25 Very Severe: 26-52
