Universal automated CBT prevention can fail

Population and setting: 5,017 pregnant users of a Japanese app, without baseline major depression.
What was found: MDE occurred in 2.35% versus 2.91%; HR 0.85 (95% CI 0.61–1.20), not statistically significant.
Limits and applicability: Positive K6 subgroup finding was post hoc. This is a counterweight to extrapolating counseling efficacy to every app.
