Knowledge questionnaire on viral hepatitis for drug service staff


This knowledge questionnaire has been developed by the EMCDDA as part of its initiative to increase access to hepatitis C care through drug services. The main aims of the knowledge questionnaire are:

  • to refresh knowledge on hepatitis C virus (HCV) and hepatitis B virus (HBV) transmission, testing and care for people who inject drugs (PWID) among those working in drug treatment settings;
  • to increase awareness of staff of the importance of knowing their own status;
  • to provide a tool for managers of drug treatment facilities, or other actors, who would like to identify the training needs of staff.

The knowledge questionnaire covers a wide range of aspects regarding HCV and HBV such as prevalence, routes of transmission, prevention measures, treatment and testing options, and international recommendations on testing and treatment. It consists of a series of true statements which provide factual information on viral hepatitis and it can be administered as an online survey or on paper. The answer format ‘I knew it already’ or ‘This is new to me’ allows participants to assess their own level of knowledge and refresh it, which facilitates an honest self assessment, avoiding a test situation with true or false statements, that may feel threatening.

An online version of the questionnaire is also available.

PDF files are made available as a convenience. In cases where the EMCDDA is not the originator of the document, please be aware that any PDFs available on this page may not be authoritative or there may be more recent versions available. While we make every effort to ensure that these files are definitive, before using or citing them, we recommend that you consult the publisher's website or contact the author(s) to check for more recent versions.

Additional information

Experiences with the questionnaire during the piloting phase suggest that it can be answered individually or in discussions in a small group, and that it can have a number of other uses, for example supporting better informed discussions with policymakers or to structure a dialogue between staff and clients at drugs services.

  • ‘This questionnaire could be also useful for the staff to discuss the subject of HCV with their clients (sort of checklist).’
  • ‘We prefer the current version of questionnaire (I heard about it/This is new to me) over true and false – to avoid putting pressure on the staff.’

Feedback from about 150 people working in drugs services in four countries who piloted the questionnaire showed that 90% of respondents found the questionnaire interesting, and 76% said that they learned something new. The majority of respondents agreed that the answer format facilitates staff to refresh their knowledge and thought people would answer the questionnaire honestly.

Note: new versions of the original knowledge questionnaire (31 Jan 2020) and additional languages were made avaialbe to mark World Hepatitis Day on 28 Jul 2020.
