Eksperimentel: positive emotion working memory (PEWM )training
The PEWM task is a computerized n-back task.
The stimulus presents 2000ms.
The longer stimulus duration compared to a standard n-back task is intended to allow participants to more elaboratedly process positive emotion.
During the PEWM, each session has 25-35 minutes.
|
Participants take 10 sessions of positive emotion working memory training with n-bak task of positive words for two-week at itinal and 8 booster sessions at 6 months follow-up.
|
|
Eksperimentel: negative emotion working memory (NEWM) training
The NEWM task was a computerized dual n-back task.
The visual stimulus presents 500 milliseconds (ms), followed by a blank screen for 2500 ms.
The auditory stimulus presents 500-950 ms at the same time.
Participants monitor both modalities.
Each session takes 25-35 minutes.
The first three sessions started with 1 n-level.
From the fourth session , it starts from 2 n-level.
The tasks are adjusted difficulty on the participant's performance.
When accuracy rates equal to or larger than 90% for both the auditory and visual response, participants give an option to advance a n level or keep the same level.
|
Participants take ten 16 × (21 + n) trial sessions of NEWM with dual n-back task with sad facial pictures for visual modality and sad words for auditory modality for 2 weeks at initial and 8 booster sessions for 2 weeks at 6 months follow-up.

Eksperimentel: Positive attention bias Training (PABT)
The PABT task was a variation of the computerized visual dot-probe task from a previous attention bias modification (ABM) study (Yang, et al., 2015, 2016).
The stimuli present 2000 ms.
The longer stimulus duration compared to a standard dot-probe task was intended to allow participants to have time to more fully process the content of the stimulus.
During the PABT, 27 neutral-positive word pairs were presented 8 times (8 × 27) in each 10-min session.
|
Participants take ten 216-trial sessions of PABT with 90% probe dot fallen on positive words for 2 weeks and eight 216-trial booster sessions for 2 weeks at 6 months follow-up.
|
|
Placebo komparator: placebo (neutral attention bias training, NABT)
The placebo task was identical to the active PABT, except 90% of the probes appeared at the neutral position, 10% at the positive position.During the training, 27 pairs of neutral-positive words are presented 8 times (8 × 27) in each 10-min session.
Participants take ten 216-trial sessions for 2 weeks at inital and 8 booster sessions for 2 weeks at 6 months follow-up.

Onset of a major depressive episode

Clinicians interviewed the participants using the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS) at initial, 6 months , 12 months and 24 months follow-ups after training and using Structured Clinical Interviews for Diagnostic and Statistical Manual of Mental Disorders, fifth edition ( SCID-5) at 5 years follow-up.
The person has at least 4 depressive symptoms and mild to moderate impairment for a probable episode of major depression, or has 5 or more than 5 symptoms and mild to moderate impairment for a definite episode of major depression.

Self-reported depressive symptoms and clinical significant changes
Tidsramme: Pre-training, post-training, 2 weeks, 4 weeks, 8 weeks, 12 weeks, 20 weeks, 24weeks, 28weeks, 32 weeks, 12 months, 24 months, and 5 year follow-ups.

Self-reported depressive symptoms assessed by Beck Depression Inventory-the second version (BDI-II).
The BDI-II contains 21 questions, each with a score from 0 to 3. The total scores range form 21 to 60.
To evaluate clinical significant changes of depressive symptoms, we follow the procedures outlined by Jacobson and Truax (Jacobson & Truax, 1991) .
A participant is classified as meeting criteria for clinically significant change if (a) the post-training score falls within the range (mean ± 2 SDs) of the nonclinical population on the basis of BDI-II data (Yang, Wu, &Peng, 2012), and (b) if they display a statistically reliable reduction in scores from pre- to post- or to folloow-up assessment based to the reliable change index.
