Treatment Response Following Adaptive PASAT Training for Depression Vulnerability: a Systematic Review and...

Area of Science:

• Cognitive Psychology
• Clinical Psychology
• Neuroscience

Background:

• Cognitive control training (CCT) is increasingly recognized for its potential to address cognitive deficits and reduce depressive symptoms.
• The adaptive Paced Auditory Serial Addition Task (aPASAT) is a specific CCT method showing promise for training cognitive control.
• Existing research on aPASAT's efficacy for depression and rumination requires systematic synthesis.

Approach:

• A systematic review and meta-analysis was conducted, searching major electronic databases (PsycINFO, MEDLINE, Embase, Web of Science, Cochrane Library).
• Nineteen studies (n=1255) including diverse populations (depressed, remitted, at-risk, healthy) were analyzed.
• The review examined immediate and follow-up effects of aPASAT training on depressive symptomatology and rumination, exploring potential moderators.

Key Points:

• Small, significant effects of aPASAT training were observed for both depressive symptoms and rumination immediately post-intervention, with sustained effects at follow-up.
• Subgroup analyses indicated greater efficacy for rumination in non-healthy populations, but not for depressive symptoms.
• Training dosage (number of sessions) did not significantly moderate the observed effects.

Conclusions:

• aPASAT demonstrates a small but significant positive impact on depressive symptoms, with both immediate and lasting effects.
• The training appears most beneficial for individuals who are at-risk, remitted from depression, or currently experiencing clinical depression.
• Future research should focus on dose-response relationships and the synergistic effects of combining aPASAT with other antidepressant interventions.
