Study Overview
Brief Summary
This study intends to explore the therapeutic effects of the development of negative attention bias modifaction and positive attention bias on depressive symptoms and redundancy through two different attention training methods: (1) neutral attention training (when neutral and sad stimuli are presented simultaneously, attention is always directed towards neutral stimuli to correct negative attention bias) and (2) positive attention training (when neutral and positive stimuli are presented simultaneously, attention is always directed towards positive stimuli to develop positive attention bias).
Detailed Description
Attention Bias Modification Training was a modified dot-probe task. In the neutral attention bias, 90% of the targets in the training group appear in the neutral word position and 10% of the targets appear in the negative word position, while 50% of the targets in the placebo group appear in the neutral word position and 50% of the targets appear in the negative word position. In the positive attention bias, 90% of the targets in the training group appear in the positive word position and 10% of the targets appear in the neutral word position, while 90% of the targets in the placebo group appear in the neutral word position and 10% of the targets appear in the positive word position. The investigators assess attention bias scores, depressive symptoms, trait anxiety, rumination and self-report attention control ability at 1-week, 2-week, 4-week, 7-week, 3-month, 4-month, 5-month, 6-month and 12-month follow-ups after training.

Outcomes
Primary Outcomes
Changes of attentional bias score
Time Frame: pre-training, post-training(2 weeks after pre-training), follow-ups(1-week,2-week,4-week,7-week,3-month( booster pre-training), 4-month (booster post-training), 5-month,6-month,12-month after post-training)
Attentional bias score tested by a typical dot-probe task
Changes of depressive symptoms
Time Frame: pre-training, post-training(2 weeks after pre-training), follow-ups(1-week,2-week,4-week,7-week,3-month( booster pre-training), 4-month (booster post-training), 5-month,6-month,12-month after post-training)
Depression symptoms tested by clinicians using the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS)
Secondary Outcomes
- Changes of self-reported depressive symptoms(pre-training, post-training(2 weeks after pre-training), follow-ups(1-week,2-week,4-week,7-week,3-month( booster pre-training), 4-month (booster post-training), 5-month,6-month,12-month after post-training))
- Changes of self-reported rumination(pre-training, post-training(2 weeks after pre-training), follow-ups(1-week,2-week,4-week,7-week,3-month( booster pre-training), 4-month (booster post-training), 5-month,6-month,12-month after post-training))
