Overview

Pre-registered experiment shows two digital interventions effectively reduce depression in American adults, suggesting short-term gains may promote behavior change.

Key Points

  • Nearly all digital, self-guided interventions improved feelings of agency and hope after use, with limited long-term impact.
  • Of the 12 tested digital single-session interventions, only two significantly reduced depression at four-week follow-up.
  • Crowdsourced methods were employed to evaluate widely diverse psychological interventions for depression.
  • Findings highlight the potential of short interventions in improving emotional states but reveal challenges in sustaining behavior change.
