The Online Privacy Literacy Scale (OPLIS)

OPLIS is a 20-item instrument designed to measure people's online privacy literacy. We understand online privacy literacy as a combination of factual or declarative ("knowing that") and procedural ("knowing how") knowledge about online privacy and data protection (Trepte et al., 2015). Accordingly, the scale is based on a multidimensional concept of privacy literacy which includes the following aspects:

  • Knowledge about institutional practices
  • Knowledge about technical aspects of data protection
  • Knowledge about data protection law
  • Knowledge about data protection strategies

In the final scale, each dimension is measured with five items respectively. For more information about the overall project and the various steps in the development of the scale, please visit the section "Project description". OPLIS was recently validated with a sample representative of German Internet users. The results of this study are published in the article "Entwicklung und Validierung der Online-Privatheitskompetenz-Skala [engl. Development and validation of the online privacy literacy scale]" in the journal "Diagnostica".
