Description of intervention(s) / exposure
BEHAVIORAL - WiserAD
BEHAVIORAL - Attention control

Experimental: Intervention - Participants will be provided with a personal login code for the study web portal via automated email and encouraged to complete the initial components of the intervention which seek to determine participants' current support and management strategies and help them to understand their specific antidepressants. They will then complete the third component which contains three sub-sections to assist in creating a personal plan to help them cease their ADs: i) Management strategies for withdrawal symptoms and opportunities to discuss the plan with their GP or trusted Mental health worker; ii) Selecting a start time to begin tapering; iii) Print out of the personalised action plan to keep and share with supportive family and/or friends. Participants will also be required to complete a daily check-in through the portal which will check current symptoms and highlight any negative changes in emotional wellbeing, they will also receive texts reminders to complete these tasks.

Experimental: Usual care - Attention Control - Participants allocated to the treatment as usual group will receive usual care plus attention control which comprises a link to the AD factsheet within the BeyondBlue website. This provides education material relevant to the participants' enrolment in the study but they will not be advised to cease or continue with their medication. GPs will not be advised of the participants allocated to this treatment arm.
