The important distinction

An unmoderated social group or an AI-generated cohort does not automatically inherit the trial result. Moderator training and safe referral routes matter.

Proactive trained peer support has prevention evidence

Population and setting: High-risk postpartum women in one 701-participant trial.
What was found: At 12 weeks, 14% versus 25% scored above the EPDS threshold; reported NNT 8.8.
Limits and applicability: Telephone support came from trained recovered peers; not equivalent to unmoderated groups or AI companions. Screening endpoint is not diagnosis.

What should a new peer group avoid?

Medical advice from unqualified members, competitive suffering, mandatory disclosure, shaming and claims that the group prevents every crisis.
