Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be recruited from advertisements in the media and from flyers within medical clinics seeing patients suffering from depression. All participants will have voluntarily provided their telephone details before being contacted by the Research Unit. Participants will initially be contacted by telephone by researchers working on the study. They will be assessed with regards to their suitability to be involved in the study. Those who are deemed suitable will be mailed the participant information sheet to read at their leisure. Those patients who wish to participate will be instructed to contact the Trial Co-ordinator to arrange a visit to the Women's Health Research Program, Monash University , The Alfred Centre, for a screening visit.

Allocation concealment will be done by sealed opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
randomization schedule will be computer generated.
