Outline content of the digital intervention

Content	Description
Reducing and stopping antidepressants	An introduction to the intervention, which addresses motivations behind withdrawal, asking participants to reflect on why they might prefer to discontinue antidepressant treatment. Guidance on when to speak to their GP/nurse and advice on following a tapering regimen.
Thinking about antidepressants	Acknowledging that antidepressant treatment is not necessarily required long term and that the mechanisms are more complex than correcting a serotonin deficiency.
I’m worried about stopping	Addressing participant fears by signposting participants to appropriate resources in ADvisor.
Dealing with withdrawal symptoms	Guidance for dealing with mild withdrawal symptoms (including guided practices for accepting/tolerating unpleasant symptoms). Advice for patients to contact their GP for assistance with moderate or severe withdrawal symptoms.
Keeping well	Relapse prevention techniques grounded in mindfulness-based cognitive therapy.
Thinking about what you value	Reflection on values and committed action to values (through goal setting), based on acceptance and commitment therapy.
Moving forward	Psychoeducation and techniques for managing distress (eg, mindfulness and behaviour activation) provided through a distress-management online intervention, Healthy Paths.
My notes	Where patients can access content from other sections where they have written their own responses (eg, their own reasons for wanting to stop antidepressants and their own warning signs and triggers for relapse).
Resources	Direct links to resources in ADvisor (eg, activity planning and information for family and friends).
