Five invitation letters were sent during August 2008 inviting the pharmacy to the study.
Recruitment was done via an e-mail sent to all students of Years 1 3 explaining the purpose and procedure of the study and inviting the students to participate, followed by a reminder e-mail 2 weeks later.
We grew up under scrutiny, the sheer size of our cohort inviting endless study -- from the rise of the "teenager" to the birth of the "midlife crisis" to the so-called "silver tsunami".
Potential participants received a letter of invitation describing the study and inviting their participation.
Study information will be mailed to childcare services inviting participation in the study.
Letters inviting participation in the study were mailed to 90 women from two family practices.
In practice only 11% of eligible women were randomised as 83% did not respond to the initial mailed letter inviting them into the study.
The mailing included a letter, signed by a named member of the practice staff, inviting participation in the study and the SPHERE study information sheet, with telephone numbers to contact the project manager or research nurse if wished.
The remaining 603 families either failed to return questionnaires to schools by the cut-off date (N = 349) or did not reply to letters from clinics inviting participation in the study (N = 254).
All potential participants will receive an invitation letter and a detailed information sheet about the study inviting them to approach the research team if they are interested in taking part.
At universities, the researcher herself informed classes about the study, inviting those interested to make contact.
