April 12, 2020 updated by: Wenhui Yang, Hunan Normal University
The purpose of this study is to test whether emotional working memory training and attention bias modification training are an effective neurobehavioral therapy to improve depressive symptoms.That is whether emotional working memory training is superior to attention bias modification training or not 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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Maintaining Positive Working memory
Maintaining positive working memory training is based on visual positive works n-back task.In this training, positive words are presented on the pictures of happy face.According to the rules, subjects are required to identify whether the word present currently is as the same type as the word presented n before then click the keys correspondingly.Each training session contains 15 blocks which are consisted with 20+n trails.
Behavioral: Working memory training
Participants complete 10 sessions of maintaining positive working memory training during a two-week period. Each session consists of 15 blocks.
Placebo Comparator: Positive Attention Bias Modification
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 10 sessions over 2 weeks. 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.
Behavioral: Positive ABMT
Participants complete 8 sessions of attention bias modification training (ABMT) during a two-week period. Each session consists of 218 trials, and the time to complete a training session is 12 minutes.
