- Pilot work: The intervention consisted of mailing (to each undergraduate student’s pigeon-hole) a pack of 4 postcards which provided brief information on depression in an attractive format. One postcard summarised information on depression as an illness; one summarised information on the causes of depression; one summarised information on the treatment of depression; and one summarised information on how to seek help for depression. Prior to the trial, the drafts were revised through feedback from a focus group of 5 students, who discussed the design and content of the draft postcards. The focus group participants were recruited from the Queen’s College, as this college did not participate in the trial. The focus group contributed to the revision of the draft questionnaire.
