Brief summary

This project will test the effectiveness and feasibility of promoting helpful self-help strategies to individuals with depressive symptoms (but not major depression) via regular emails. The effect of these will be compared to receiving emails containing general information about depression. We wish to see whether the emails reduce depressive symptoms in participants, and whether they prevent participants from developing major depression.

Interventions

Participants will receive 12 emails over 6 weeks. Each email will contain a self-help strategy for coping with depressive symptoms. The email will contain information about why the strategy will be effective, tips for implementing the strategy and overcoming barriers, and how to set a goal to implement the strategy. Strategies are based on previous research published by the trial co-ordinators.
