Imiquimod: physicians’ awareness, attitudes and experiences
 Design
  Survey design
  The survey was intended for all gynaecologists in the Netherlands who regularly perform colposcopies and treat CIN/VAIN. Because a specific mailing list was not available, all hospitals in the Netherlands were contacted by phone to identify these specialists.
 IRB (Institutional Review Board) approval and informed consent process
 IRB approval
   IRB approval was not necessary for this study.
   Informed consent
  The participants were contacted by email. The introduction email contained information about the purpose of the study, the identity of the investigators, the time investment for the survey and that completing the data was anonymous.
   Data protection
 The following commercial web survey provider was used: www.surveymonkey.com. An e-mail link to the survey was created. E-mail addresses of respondents were automatically stored by the survey provider, for the purpose of sending reminder messages to non- responders. E-mail addresses could not be linked to individual surveys, ensuring anonymity of participants. The survey provider account is only accessible to the main investigator, for data protection purposes.
 Development and pre- testing
  Development and testing
  A non-validated anonymous electronic questionnaire was designed by the authors. The questions were composed by an expert panel of four gynaecological oncologists with experience in colposcopy and treatment of VAIN/CIN. The web survey was tested before the start of the study by colleagues.
 Recruitment process and description of the sample having access to the questionnaire
  Open survey versus closed survey
   The survey was closed: participants could only complete the survey through a link in the invitation e-mail.
   Contact mode
 The target population was contacted by e-mail. A second and third invitation was sent after three and six weeks.
 Advertising the survey
   No advertising was used.
