Beskrivelse
Inclusion Criteria:
- Ages 18-55
- Principal psychiatric diagnosis of major depressive disorder
- Patient Health Questionnaire - 9 item score ≥ 10
- Ability to read and speak English sufficiently to complete study procedures
Exclusion Criteria:
- History of psychosis, mania, or substance dependence
- Current severe medical disorder that requires inpatient treatment or frequent medical follow ups including but not limited to: unstable hypertension, unstable angina, unstable diabetes mellitus, unstable cardiac arrhythmias, transient ischemic attacks, sever coronary artery disease, sever peripheral vascular disease, severe hepato-gastro-intestinal disease, severe infectious disease (e.g. HIV), recurrent severe headache or migraine, fainting spells, seizures, and history of traumatic brain injury with loss of consciousness > 30 minutes
- Current use of the following medications: antidepressants, benxodiazepines, antipsychotics, mood stabilizers, or other drugs that can acutely affect the hemodynamic response (methylphenidate and acetazolamide)
- Caffeine intake > 10 cups/day or recent significant changes in consumption
- MRI exclusions, including claustrophobia, cardiac pacemaker, metal fragments in eyes/skin/body (shrapnel), aortic/aneurysm clips, prosthesis, by-pass surgery/coronary artery clips, hearing aid, heart valve replacement, shunt (ventricular or spinal), electrodes, metal plates/pins/screws/wires, or neuro/bio-stimulators (TENS unit), persons who have ever been a metal worker/welder, history of eye surgery/eyes washed out because of metal, women who are or may be pregnant (determined by a positive pregnancy test), women using an intrauterine device, vision problems uncorrectable with lenses, inability to lie still on one's back for 60 minutes; prior neurosurgery; older tattoos with metal dyes; unwillingness to remove nose, ear, tongue or face rings.
- Concurrent psychosocial treatment: Participants completing ongoing psychosocial treatment will be required to meet a 12-week stability criteria so that symptom changes as a result of other psychosocial treatments are not confounded with changes due to the research.
- Inability to complete the initial assessment battery or behavioral training sessions.
- Clinical conditions assessed by the interviewer that necessitate more imminent clinical care (e.g., active suicidal ideation). These criteria are in place so participants with these other, more several symptoms can be referred for appropriate mental health services.

Eksperimentel: Approach-positive AAT
Computerized AAT procedure designed to increase automatic approach responses for positive social cues.
|
One session of approach-positive AAT (Aim 1 and 2) followed by 4 sessions of approach-positive AAT over 2 weeks concurrent with a brief computer-delivered behavioral activation treatment for depression (Aim 3).
|
|
Placebo komparator: Control AAT
Computerized AAT procedure in which there is no contingency between arm movement and positive social cues.
|
One session of control-AAT (Aim 1 and 2) followed by 4 sessions of control-AAT over 2 weeks concurrent with a brief computer-delivered behavioral activation treatment for depression (Aim 3).
