Hypothesis
Does self-guided psychological treatment effectively reduce depressive symptoms?
Conclusion
Self-guided psychological treatment has a small but significant effect on reducing depressive symptoms.
Supporting Evidence

- The NNT for self-guided treatment was 6.41, meaning one in every six patients benefits.
- At follow-up, the effect size remained significant with d=0.23.
Takeaway
This study shows that people can help themselves feel better when they're sad, even without a therapist.

Potential Biases
