SQP 3.0 data

This dataset comprises survey questions administered in general population surveys, mostly from the European Social Survey, from the years 1979 to 2017. Each question is accompanied by detailed codings of its characteristics based on the coding scheme developed by Saris & Gallhofer (2007). Additionally, the dataset provides information on the measurement validity, reliability, and overall quality of each question. This rich collection serves as the foundation for meta-analyses and for training the prediction algorithm in the Survey Quality Predictor (SQP) tool, enabling systematic evaluation and prediction of survey question quality across studies and time periods.
