The PEN prototype questionnaire forms the basis for data collection in the individual PEN studies. Researchers may, however, add modules to collect additional data for their particular research topic. The questionnaire is the result of a long consultative process among PEN resource persons and partners. The prototype questionnaire gathers the information required in the common data bank (CDB) of PEN. The questionnaire must be used together with the Technical Guidelines, which define key concepts, elaborate and explain the questions, and specify common codes to be used (those in the “code-xxx” format in the questionnaire).
