Exclusion Criteria

Treatment within 4 weeks of randomization with any non-SSRI antidepressant, antipsychotic, mood stabilizer, standing benzodiazepine, stimulant, or stimulant-like agent.
1. Allowed exception 1: Concomitant benzodiazepines, at a stable dose, that have been taken for at least one year with no history of abuse.
2. Allowed exception 2: Effexor, duloxetine (Cymbalta) or milnacipran (Savella) can serve as main SSRI treatment.
3. Allowed exception 3: Combinations of SSRIs (ex. Zoloft & Lexapro concomitantly) are acceptable as main SSRI treatment.

Significant suicide risk.
Current treatment-resistant episode of MDD.
A primary diagnosis of an Axis I disorder other than MDD.
History of a psychotic disorder, dysthymia, antisocial personality disorder, BPD, or mental retardation.
History of a substance use disorder, with the exception of nicotine dependence, within 12 months prior to screening.
History of stimulant abuse, prescription drug abuse, and eating disorders.
Initial insomnia at screening that is not adequately controlled by medications. Subjects with recent history of unstable insomnia as defined by active or poorly controlled symptoms of insomnia within the past 1 month will be excluded.
Co-morbid medical conditions including a structural heart defect or rhythm abnormality that might be exacerbated by stimulant therapy; hypertension as measured by a resting sitting systolic blood pressure of > 149mmHg or diastolic blood pressure > 95mmHg; tachycardia as measured by a sitting pulse rate of >100 bpm or <50 bpm after resting for 5 minutes.
Allergy, hypersensitivity, intolerance, or history of non-responsivity to stimulant medications.
History of non-responsivity to CBT or well-being therapy.
Women who are pregnant or breastfeeding.
Glaucoma or hyperthyroidism
Current concomitant therapy is only permitted if it is supportive therapy (not specifically CBT) and has been ongoing for at least one year. However, if a subject has been in therapy for less than one year and wishes to discontinue or take a hiatus from their current therapy before coming in for a screening visit, this will be allowed. Additionally, subjects may not enter into other talk therapies for the duration of this study.

Brief Summary

This study aims to identify a novel enhancement strategy for residual symptoms of major depressive disorder (MDD) Dopamine (DA) has been viewed as a "pleasure neurotransmitter" for over 30 years. Yet recent data from animal and human studies suggest that dopamine has greater effects on "wanting" than on "liking." Therefore, the investigators of this study have hypothesized that amphetamine/d-amphetamine (AMPH), a medication which increases dopamine transmission in the reward centers of the brain, may have a more powerful antidepressant effect in combination with well-being therapy (WBT), a specific type of cognitive-behavioral therapy, which helps individuals with depression to increase their contact with natural rewards and decrease reward-interfering thoughts. The investigators will test their hypothesis by randomizing 40 individuals with residual symptoms of depression, already taking an antidepressant that affects serotonin (e.g. Prozac, Paxil), to 8 weeks of treatment with either WBT in combination with AMPH, or WBT with pill placebo. The effectiveness of each treatment will be measured using a reliable scale, called the Hamilton Depression Rating Scale. The investigators have also hypothesized that people assigned to the stimulant/WBT group will have greater improvements in functioning, well-being, and positive affectivity than those the people assigned to the WBT/placebo group.

Detailed Description

The study will have 11 visits occur over 8 weeks with study visits scheduled weekly or biweekly. Detailed Description: The study visit occurrences are as follows: Week 0- Screening Visit Week 1- Baseline Visit Week 2- one phone visit and one clinic visit in one week Week 3- one phone visit and one clinic visit in one week Week 4- one visit in one week Week 5- one visit in one week Week 6- one visit in one week Week 7- one visit in one week Week 8- one visit in one week WBT description Four licensed therapists, who have been trained and certified in WBT, will provide weekly sessions of 30 to 50 minutes in duration. Therapists will follow the procedures outlined in the WBT manual. The initial sessions (weeks 0-2) will be focused on identifying and contextualizing episodes of well-being. The intermediate sessions (weeks 3-5) will be focused on modifying cognitions and behaviors, which lead to premature interruption of well-being, and optimizing cognitions and behaviors, which have been idiographically linked to enhanced well-being. Final sessions (weeks 6-8) will apply the Psychological Well-Being scales (PWB) to refine treatment according to Ryff's dimensions of well-being. Additional principles and techniques of WBT include reappraisal, mood-charting, scheduling of activities, shaping, problem-solving, and assertiveness training. Medication Schedule Participants will receive treatment with the stimulant, amphetamine/d-amphetamine, or matched placebo. Participants will start at 1 pill (placebo or 5 mg amphetamine/d-amphetamine) in the morning and 1 pill (placebo or 5 mg amphetamine/d-amphetamine) at noon. The treatment will then be flexibly adjusted up or down by a study clinician based on participant's response. Dose ranges will be 1-3 pills (placebo or 5 mg amphetamine) in the morning and 1-3 pills (placebo or 5 mg amphetamine) at noon.
