Overview
Brief Summary
The purpose of this study is to test whether attention bias modification training is an effective neurobehavioral therapy to improve depressive symptoms.That is whether attention bias modification training is superior to placebo in reducing depressive symptoms over 1 year after training.
Detailed Description
Attentional bias has been theorized to play a critical role in the onset and maintenance of depression. Attentional bias modification training (ABMT), an experimental paradigm that uses training to induce adaptive attentional bias, was developed to test the causal model and this has therapeutic implications in depression.To test the effect of ABMT on treatment of depressive symptoms, a randomized, double-blind, placebo and blank controlled trial is conducted in college students who are experiencing mild-to-severe symptoms of depression.

Outcomes
Primary Outcomes
Depressive Symptoms Measured by Beck Depression Inventory-II
Time Frame: From the baseline to posttraining, 2-, 4-, 8-week, 3-, 7-month follow-ups after training
Beck Depression Inventory-II(BDI-II) contains 21 items and rates the depressive symptoms for the past two weeks. Each question provides for a response of 0 to 3. A zero response means the depressive symptom is not present; a 1 means the symptom is present, a 2 means the symptom is moderate, and a 3 means the symptom is severe. The total BDI-II score is the sum of the individual items; total BDI-II scores can range from 0 to 63. Cutoff points developed by Beck, Steer, \& Brown (1997) for the total BDI-II are: 0 to 13, nondepressed; 14 to 19, mild depression; 20 to 28, moderate depression; 29 or more, severe depression.
Secondary Outcomes
- Anxiety and Rumination Symptoms Measured by State-Trait Anxiety Inventory-Trait(STAI-T) and Rumination Response Style（RRS）(From baseline to post-training, 2-, 4-, 8-week, 3- , 7-month follow-ups after training)
