Neutral and Positive Attention Bias Modification Training for Young Adults With Depressive Symptoms
Condition: Depressive Disorder
MeSH terms: Depressive Disorder
Study type: Interventional

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.
    

Intervention name(s): Neutral ABMT; Positive ABMT
Intervention type(s): Behavioral; Behavioral
Intervention description(s): In the neutral attention bias, there are 108 pairs of neutral-negative words, 54 pairs of which are used in the training group and 54 pairs of which are used in the placebo group. The word pairs in each group are repeated 4 times, with a total of 216 trial. Participants received 8 sessions over 2 weeks (1 session every other day).In booster ABMT, participants received 4 sessions over 2 weeks (1 session every three days).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, there are 54 pairs of neutral-negative words, 27 pairs of which are used in the training group and 27 pairs of which are used in the placebo group. The word pairs in each group are repeated 8 times, with a total of 216 trial.Participants received 8 sessions over 2 weeks (1 session every other day). In booster ABMT, participants received 4 sessions over 2 weeks (1 session every three days).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.
