The award-winning Survey Quality Predictor (SQP, http://sqp.upf.edu/) software was created by RECSM co-founder Willem Saris and is continuously improved and updated. The development of the next version SQP3.0 is led by Wiebke Weber who collaborates with researchers of the ASQME research group as well as the Sociometric Research Foundation. The new version with many new features is expected for the end of 2019.
SQP is a database of survey questions which allows users consulting existing questions and their measurement quality, adding newly created questions and predict their measurement quality, and consulting translations of survey questions. The SQP database contains a wide range of survey questions concerning many different topics in many different forms and languages.
